The spectra were analyzed using the Bruker biotyper and the Autof ms1000 systems. The results were confirmed by 16/18S rRNA sequencing. Results reveal that the accuracies of isolates identification by Bruker biotyper successfully identified 83.8%, 96.0%, and 95.3% after performing the DCTM, OTEM, and ITEM, respectively, while the Autof ms1000 identified 97.5%, 100%, and 99.7%. These data suggested that the identification rates are comparable among the three preparation methods using the Autof ms1000 and Bruker microflex LT systems but the OTEM is more suitable and necessary for clinical application, owing to its key advantages of simplicity and accuracy.
Intravenous azithromycin (AZM) has been widely used in children worldwide, but there still remains much concern regarding its off-label use, which urgently needs to be regulated. Therefore, we developed a rapid advice guideline in China to give recommendations of rational use of intravenous AZM in children.

This guideline focuses on antimicrobial therapy with intravenous AZM in children. The Delphi research method was used to select questions. A systematic literature review was also conducted. Data were pooled and ranked according to the GRADE system. Recommendations were developed based on expert clinical experience, patients' values and preferences, and evidence availability. After an external review, the recommendations were revised and approved.

This guideline included eighteen recommendations that covered four domains (a) Indications the treatment of pneumonia caused by atypical but common pathogens, such as Mycoplasma pneumoniae, Chlamydia trachomatis or Chlamydophila pneumoniae and Legionella pne-designed researches should be conducted on the off-label use of intravenous AZM in children.
Following banning of the pesticide lindane in most counties, wireworms (i.e., the soil-living larval stages of click beetles) have become major pests of a variety of economically important field crops. Hypnoidus bicolor is a common pest species in the Canadian Prairies. However, little is known about its life history, which impedes the development of effective integrated pest management (IPM) strategies. Population genetic approaches have the potential to assist in the development of IPM.

We sequenced a 622-bp fragment of the COX1 gene from 326 H. bicolor wireworm and click beetles collected from 13 localities on the Canadian Prairies. Two genetically distinct (>4.66% sequence divergence) clades were identified, suggesting that they may be part of a species complex. Clade A predominated and increased in prevalence the further east samples were collected, whereas the opposite was true for clade B. Clade B appears to be comprised of two mitochondrial DNA groups, however, one group was represented by onlyl patterns and population dynamics. © 2021 Society of Chemical Industry.Nonalcoholic fatty liver disease (NAFLD) occurs in patients with type 2 diabetes mellitus (T2DM). Trelagliptin is an important member of the Gliptins family, which has been recently licensed for the treatment of T2DM. However, the pharmacological function of trelagliptin in NAFLD has not been previously reported. In this study, we aimed to investigate the roles of trelagliptin in the development of NAFLD in a mouse model. To induce NAFLD disease, C57BL/6 mice were fed a high-fat diet for 10 weeks. Our results indicate that trelagliptin reduced plasma lipid levels in NAFLD mice by reducing triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Treatment with trelagliptin exhibited an improvement in insulin resistance. More important, trelagliptin improved liver function by reducing alanine transaminase, aspartate transaminase, lactate dehydrogenase, and total bile acid. In addition, trelagliptin ameliorated oxidative stress in the liver of NAFLD mice by reducing malondialdehyde and increasing the levels of reduced glutathione and superoxide dismutase activity. Also, the enzyme-linked immunosorbent assay results indicate that trelagliptin-treated mice displayed anti-inflammatory properties by reducing the levels of interleukin 1β (IL-1β), IL-6, and tumor necrosis factor-α. Hematoxylin and eosin and Oil red O staining show that trelagliptin treatment ameliorates liver tissue damage and hepatic lipid deposition. Mechanistically, we found that the administration of trelagliptin reduced the activity of hepatic nuclear factor-κB but increased the activity of AMP-activated protein kinase. These findings suggest that trelagliptin might become a promising therapeutic agent for the treatment of NAFLD.
The study aimed to estimate the prevalence of active or previous SARS-CoV-2 infection in asymptomatic adults admitted for elective surgery in Australian hospitals. This surveillance activity was established as part of the National Pandemic Health Intelligence Plan.

Participants (n = 3037) were recruited from 11 public and private hospitals in four states (NSW, Vic, SA and WA) between 2 June and 17 July 2020, with an overall 66% participation rate. Presence of SARS-CoV-2 viral RNA was assessed by Reverse Transcriptase - Polymerase Chain Reaction (RT-PCR) analysis of nasopharyngeal swabs taken after induction of anaesthesia. Presence of anti-SARS-CoV-2 antibodies was assessed by analysis of serum collected at the same time using a novel dual-antigen ELISA assay.

No patient (0/3010) returned a positive RT-PCR result. The Bayesian estimated prevalence of active infection of 0.02% (95% probability interval 0.00-0.11%), with the upper endpoint being 1 in 918. Positive serology (IgG) was observed in 15 of 2991 patients, with a strong positive in five of those individuals (Bayesian estimated seroprevalence 0.16%; 95% probability interval 0.00-0.47%).

These results confirm that during periods of low community prevalence of SARS-CoV-2 elective surgery patients without fever or respiratory symptoms had a very low prevalence of active SARS-CoV-2 infection.

Quercetin, a bioactive component of Solanum muricatum extracts, promotes the osteogenic differentiation of BMSCs and ameliorates the symptoms of osteoporosis in vivo. However, the detailed mechanism underlying this process remains unclear. The study aims to reveal the regulatory mechanism of quercetin in BMSCs. Mouse BMSCs (mBMSCs) were isolated from the bone marrow and characterized by flow cytometry. QRT-PCR and western blot assays were performed to evaluate the expression levels of related genes and proteins. Alkaline phosphatase (ALP) staining and Oil Red O staining of lipids were used to estimate the osteogenesis and adipogenesis levels of mBMSCs, respectively. Quercetin treatment (2 and 5 μM) induced significant upregulation of antioxidant enzymes, SOD1 and SOD2, in mBMSCs. Quercetin promoted osteogenic differentiation and inhibited adipogenic differentiation of mBMSCs. Quercetin treatment enhanced the phosphorylation of AMPK protein and upregulated the expression of SIRT1, thus activating the AMPK/SIRT1 signaling pathway in mBMSCs. Quercetin promoted osteogenic differentiation and antioxidant responses of mBMSCs by activating the AMPK/SIRT1 signaling pathway.Procrastination is a prevalent and universal problematic behavior, largely impairing individual's health, wealth and well-being. Substantial studies have confirmed that conscientiousness, one of the big five personality, showed markedly inverse relation with procrastination. However, it is hitherto unknown about the neural basis underlying the impact of conscientiousness on procrastination. To address this issue, we employed the voxel-based morphometry (VBM) and resting-state functional connectivity (RSFC) methods to explore the neural substrates of conscientiousness responsible for procrastination (N = 330). In line with previous findings, the behavioral results showed a strong negative correlation between conscientiousness and procrastination (r = -.75). The VBM analysis found that conscientiousness was positively correlated with gray matter (GM) volumes in the left dorsal-lateral prefrontal cortex (dlPFC), right orbital frontal cortex (OFC) and right putamen, but negatively correlated with that in the left insula. Moreover, the RSFC results revealed that both dlPFC-IPL (inferior parietal lobule) and dlPFC-PCC (posterior cingulate gyrus) functional connectivity were positively associated with conscientiousness, while the functional connectivity of parahippocampal gyrus (PHC)-putamen and insula-IPL were negatively associated with conscientiousness. More importantly, the structural equation modeling (SEM) integrating RSFC results were well fitted for the influence process of conscientiousness on procrastination by both self-control (i.e., dlPFC-IPL, dlPFC-PCC) and motivation pathways (i.e., PHC-putamen, insula-IPL). The current findings suggest that self-control and motivation could be the two neural pathways underlying the impact of conscientiousness on procrastination, which provides a new perspective to understand the relationship between conscientiousness and procrastination.HIV-infected patients have a higher risk of developing cutaneous reactions to drugs than the general population. Severe cutaneous adverse reactions (SCARs) are not uncommon in patients taking antiretroviral therapy (HAART]. To evaluate HLA class I and II allele frequencies in HIV patients on HAART who develop SCARs due to nevirapine (NVP] or efavirenz (EFZ] containing regime and compare this genotype composition with HAART tolerant patients and healthy organ donors. A case-control study for 4 years was conducted with four subsets of patients hailing from north-east IndiaCohort 1- HIV seropositive patients who developed SCARs due to EFZ (n = 8];Cohort 2 - HIV seropositive patients who developed SCARs due to NVP (n = 15]; Cohort 3 -HIV seropositive NVP/EFZ-tolerant patients (n = 18]; Cohort 4 - Healthy HIV seronegative organ donors (n = 169].Cohort 3 & 4 acted as control-group. These patients were genotyped for the HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA-DQB1, and HLA-DPB1 by a sequence-based HLA typing method. HLA-DRB1*0301 allele revealed a significant association with EFZ regimen-induced SCARs in 62.5% patients compared with only 5.56% observed in HAART-tolerant patients and 4.14% in healthy organ. HLA-B*3505was found to be significantly associated with NVP induced SCARs. We found significant novel association of HLA-DRB1*0301 with EFZ induced SCARs in North-East Indian HIV patients. Thus, HLA-DRB*0301 may be useful as a genetic marker to avoid EFZ induced serious cutaneous rashes. The molecular HLA characterization of these alleles may provide a novel insight into the immunological basis of the antiretroviral drug reactions.

Microclimates are a particularly important consideration in topographically heterogeneous landscapes, while in some habitats, such as forests and woodlands, microclimates are also extremely labile and affected by management practices that could consequently be used to offset climate change impact. This study explored a conservation priority guild-cyanolichen epiphytes in temperate rainforest-quantifying the niche response to macroclimate, and landscape or woodland stand structures that determine the microclimate. Based on epiphyte survey in a core region of European temperate rainforest (western Scotland), a 'random forest' machine-learning model confirmed a strong cyanolichen response to summer dryness, as well as the effects of distance to running water, topographic heatload and tree species identity, which modify the local moisture regime and/or lichen growth rates. By quantifying this response to macroclimate, landscape and stand structures, it was possible to estimate an extent to which woodland may be expanded in the future, to offset a negative effect of increasing summer dryness projected through to the 2080s. Using current policy as a yardstick, sufficient woodland expansion could be delivered relatively quickly for median impacted sites, but with times to woodland delivery extending over 10, 20 and 25 years for sites at the 75th, 90th and 95th percentiles of cyanolichen decline. Furthermore, the extent of new woodland required, and delivery times, increase almost threefold on average, as new woodland becomes distributed over wider riparian zones. These contrasting implications emphasize an urgent need for afforestation that achieves targeted spatial planning responsive to microclimates as refugia.
Online prostate cancer communities (OPCaCs) have emerged as a new source of support, not bounded by geographic barriers, for men living with prostate cancer. This scoping review mapped the existing literature to explore the characteristics and benefits of OPCaCs, identify knowledge gaps, and direct future research.

A six-step methodological framework for scoping reviews was followed. Four electronic databases were searched for relevant studies. Two authors independently screened titles and abstracts, and full texts, against predefined criteria empirical research, post 1990, in English-language peer-reviewed journals; participants included prostate cancer survivors; and research explored online peer support. Data were extracted from the studies and quality assessed.

The search yielded 905 studies, with 21 selected for synthesis. Despite significant increases in online forum membership, in the last decade, nearly half of the research was conducted over a decade ago. Three studies were rated high quality, the rest moderate. All but one of the studies were observational and cross-sectional. Men reported that sharing information helped them deal with their diagnosis and treatment side effects. They also gained a sense of camaraderie with men who shared similar experiences. Due to divergent methodologies and reporting standards, assessment regarding OPCaC efficacy is not possible.

OPCaCs may be a cost-effective and accessible resource for delivering peer support to men living with prostate cancer. While self-reported evidence as to the benefits of OPCaCs exists, more longitudinal comparative studies, utilising consistent measurement approaches, are needed to support the claims.

In particular, GT4r subtype has demonstrated high rates of treatment failure. In the absence of routine viral sequencing in sub-Saharan Africa, it is important to identify sociodemographic, epidemiologic, and clinical characteristics that may be associated with GT4r infection. Methods A secondary analysis was performed on data from 300 adults with HCV GT4 enrolled in a prospective trial assessing the safety and efficacy of sofosbuvir-ledipasvir in Rwanda in 2017. The association between characteristics at enrolment and GT subtype was assessed by chi-square analysis and logistic regression. In multivariate analysis, there were a higher proportion of participants with GT4r subtype with age 1 million IU/ml (OR 3.4, 95% CI 1.6-6.9, p = 0.001). Rwandan adults with GT4r are more likely to be younger, have a history of hospital admissions and surgeries and have more active or advanced liver disease compared to those with other GT4 subtypes. In the absence of advanced diagnostics to assess GT subtype, patients with these characteristics may warrant closer monitoring for treatment failure or alternative DAA regimens. More treatment experience with diverse DAA regimens is urgently needed for GT subtypes particular to this region.Alternative methods for restoring tropical forests influence the ecological processes that shape recruitment of understory species. In turn, the traits of species recruited will influence the ecological processes the forests provide now and over the long term. We assess the phylogenetic and functional structure of seedlings beneath monoculture plantations, mixed-species plantations (both active restoration) and regenerating selectively logged native forests (passive restoration), considering traits of specific leaf area (SLA, including within-species variation), leaf nitrogen and phosphorus content, life-form, potential plant height, and dispersal type. Monoculture plantations comprised seedlings that were more closely related then would be expected by chance (i.e., phylogenetically clustered), and regenerating forest contained species more distantly related then would be expected by chance (i.e., phylogenetically overdispersed). This suggests that seedlings beneath monocultures assemble through environmentalegeneration capacity, many of which are of conservation significance (under the IUCN Red List). Reforestation projects should maximize desired ecological services (including conservation value) by actively managing for the recruitment of species that are phylogenetically and functionally (including intraspecifically) distinct. This management aim will increase the probability of fulfilling a wider array of niche spaces and potentially increase the diversity of ecosystem services provided.
Calcium (Ca
)-binding proteins in the saliva of herbivorous insects function as effectors to attenuate host plant defenses and thus improve insect feeding performance. Silencing these genes via transgenic plant-mediated RNAi is thus a promising pest control strategy. However, their sequences and functions in the small brown planthopper Laodelphax striatellus (SBPH) remain to be investigated.

We identified a putative EF-hand Ca
-binding protein (LsECP1) in SBPH watery saliva. LsECP1 was expressed extremely high in the salivary glands but at a low level during the egg stage. Transient LsECP1 expression in rice cells indicated its cytoplasm and nucleus localization. The bacterially expressed recombinant LsECP1 protein exhibited Ca
-binding activity. Rice plants fed by SBPH nymphs with knocked down LsECP1 exhibited higher levels of cytosolic Ca
, jasmonic acid (JA), jasmonoyl-isoleucine (JA-Ile) and hydrogen peroxide (H
O
). Consistently, application of heterogeneously expressed LsECP1 protein suppressed wound-induced JA, JA-Ile and H
O
accumulation in rice. Thus, LsECP1 knockdown by dsRNA injection resulted in reduced feeding, fecundity and survival rates of SBPH reared on rice plants. Transgenic rice plants constitutively expressing LsECP1 dsRNA were produced, and plant-mediated LsECP1 knockdown enhanced rice resistance to SBPH.

SBPH LsECP1 acts as an effector to impair host rice defense responses and promotes SBPH performance. This discovery provides a potential gene target for plant-mediated RNAi-based pest management. © 2021 Society of Chemical Industry.

It mainly occurs in patients with advanced chronic kidney disease and sometimes leads to complications with a fatal outcome. In this report, we describe the case of a 67-year-old male patient with end stage renal disease presenting painful skin ulcers on his lower limbs. The lesions had progressively grown and were associated to severe pain and decreased quality of life. The ulcers did not respond to conventional treatments and the patient underwent skin biopsy of these lesions obtaining anatomopathological findings compatible with calciphylaxis. In this report, we present an innovative treatment for skin ulcers secondary to calciphylaxis using cryopreserved amniotic membrane (AM) as a dressing in order to promote epithelialization of the wounds. After four applications, healing of the main ulcer and reduction in pain was achieved. In summary, applying cryopreserved AM probed to be a promising strategy to reduce pain and to enhance epithelialization and healing of chronic non-responsive ulcers in calciphylaxis.
To assess the clinical and survival features of nasopharyngeal carcinoma (NPC) with consistently negative Epstein-Barr virus (EBV) DNA level.

Propensity score matching (PSM) method was used to create well-balanced cohorts. Kaplan-Meier method and Cox proportional hazards models were performed to conduct survival analysis.

Four hundred and eighty patients were enrolled. Patients with consistently negative plasma EBV DNA level had a greater chance to present a relatively earlier T and N classification compared with those with positive EBV DNA level (p < .001; p = .015). And patients with consistently negative EBV level were significantly associated with preferable 3-year DFS (95.0% vs. 84.4%, p = .004), DMFS (98.3% vs. 89.4%, p = .009), and OS (100% vs. 97.6%, p = .004).

NPC patients with consistently negative EBV DNA level performed an earlier clinical stage and negative EBV DNA level was related to preferable survival outcomes.

Recent advances in transcatheter procedures and improved outcomes after valve surgery mean that intervention can (and should) be considered in all patients - even the elderly and those with multiple comorbidities - at earlier stages of the natural history of primary VHD, before the onset of irreversible left ventricular dysfunction (and frequently before the onset of symptoms). All patients with known VHD should be monitored carefully in the setting of a heart valve clinic and those who meet guideline criteria for surgical or transcatheter intervention referred for intervention without delay. High quality evidence for the use of medical therapy in VHD is limited and achieving target doses in an elderly and comorbid population frequently challenging. Furthermore, determining whether the valve or ventricle is the principal disease driver is crucial (although the distinction is not always binary, and often unclear). Guideline-directed medical therapy remains the mainstay of treatment for secondary mitral regurgitation - although up to 50% of patients may fail to respond and should be considered for cardiac resynchronization, transcatheter or surgical valve intervention. Early and definitive management strategies are essential and should be overseen by a specialist Heart Team that includes a Heart Failure specialist. In this article, we provide an evidence-based summary of approaches to the medical treatment of VHD and clinical guidance for the best management of patients in situations where high quality evidence is lacking.
To investigate the impact of expression mode electric breast pump or hand expression, and timing of sample collection pre- and post-milk ejection on human milk (HM) bacterial DNA profiles.

Three HM samples from the same breast were collected from 30 breastfeeding mothers a pre-milk ejection pump-expressed sample (pre-pump), a post-milk ejection pump-expressed sample (post-pump) and a post-milk ejection hand-expressed sample (post-hand). Full-length 16S rRNA gene sequencing was used to assess milk bacterial DNA profiles. Bacterial profiles did not differ significantly based on mode of expression nor timing of sample collection. No significant differences were detected in the relative abundance of any OTUs based on expression condition (pre-pump/ post-pump and post-pump/post-hand) with univariate linear mixed-effects regression analyses (all P-values>0·01; α=0·01). Similarly, no difference in richness was observed between sample types (number of observed OTUs post-pump/post-hand P=0·13; pre-pump/post-pump P=0. 45).

Bacterial DNA profiles of HM did not differ according to either expression method or timing of sample collection.

Hand or pump expression can be utilized to collect samples for microbiome studies. This has implications for the design of future HM microbiome studies.

Such a scenario also applies to mycotoxins, fungal secondary metabolites with a pre-eminent role in plant infection. In this work, we aimed to describe the effect of the interplay between Zea mays (maize) and aflatoxin B1 (AFB1) at the tissue and organ level. To address this challenge, we used atmospheric pressure scanning microprobe matrix-assisted laser desorption/ionization mass spectrometry imaging (AP-SMALDI MSI) to investigate the biotransformation, localization and subsequent effects of AFB1 on primary and secondary metabolism of healthy maize plants, both in situ and from a metabolomics standpoint. High spatial resolution (5 µm) provided fine localization of AFB1, which was located within the root intercellular spaces, and co-localized with its phase-I metabolite aflatoxin M2. We provided a parallel visualization of maize metabolic changes, induced in different organs and tissues by an accumulation of AFB1. According to our untargeted metabolomics investigation, anthocyanin biosynthesis and chlorophyll metabolism in roots are most affected. The biosynthesis of these metabolites appears to be inhibited by AFB1 accumulation. On the other hand, metabolites found in above-ground organs suggest that the presence of AFB1 may also activate the biochemical response in the absence of an actual fungal infection; indeed, several plant secondary metabolites known for their antimicrobial or antioxidant activities were localized in the outer tissues, such as phenylpropanoids, benzoxazinoids, phytohormones and lipids.Cine magnetic resonance imaging (MRI) is an emerging modality for evaluating left ventricular (LV) motion/deformation patterns, which may have potential to identify LV dysfunctions underlying postcapillary pulmonary hypertension (PH). The aim of this study was to test the hypothesis that cine MRI-derived LV motion/deformation indices can be used to identify an elevated left heart pressure in PH. This was a retrospective study, which included 26 precapillary and 28 postcapillary PH patients (23 males, 58.9 ± 13.5 years old). All patients underwent right heart catheterization (the "reference standard") and cardiac MRI. Balanced steady-state free precession cine sequence acquired at 1.5 T was used. Cine MRI datasets were analyzed by using heart deformation analysis. LV motion/deformation indices were measured through 25 phases within a cardiac cycle. Peak LV displacement, velocity, strain, and strain rates at systole, early and late diastole were compared between the two patient groups using t-tests. The Pearsonestimate elevated left heart pressure in PH. LEVEL OF EVIDENCE 3 TECHNICAL EFFICACY STAGE 1.Teledermoscopy is a novel diagnostic tool for the prevention, diagnosis, and treatment of skin disease when direct visualization of lesions is difficult. It is an economically viable option that can complement telehealth visits and that providers can utilize to identify melanocytic lesions and optimize care with diagnostic accuracy comparable to face-to-face (FTF) diagnosis. Teledermoscopy is invaluable in monitoring chronic conditions that require frequent follow-up and treatment optimization. Inclusion of clinical and dermoscopic images has been shown to improve the diagnostic accuracy of teledermatology services, thereby reducing healthcare costs. Teledermoscopy is also non-discriminatory, as diagnostic accuracy is similar in lighter and darker skin types. It has been shown to improve patient access to specialty services and reduce the number of "no-shows" at FTF clinics and length of surgery waiting times. Mobile teledermoscopy is user-friendly, feasible, and economically viable, as inexpensive mobile dermatoscopes have emerged on the market to reduce consumer out-of-pocket costs. Research is limited on teledermoscopy's utility in diagnosing pre-cancerous and cancerous skin lesions in adults, particularly complex pigmented lesions. Further research is recommended to investigate the role of dermoscopic expertise and artificial intelligence on the evaluation of teledermoscopic images.Population genomic approaches can characterize dispersal across a single generation through to many generations in the past, bridging the gap between individual movement and intergenerational gene flow. These approaches are particularly useful when investigating dispersal in recently altered systems, where they provide a way of inferring long-distance dispersal between newly established populations and their interactions with existing populations. Human-mediated biological invasions represent such altered systems which can be investigated with appropriate study designs and analyses. Here we apply temporally restricted sampling and a range of population genomic approaches to investigate dispersal in a 2004 invasion of Aedes albopictus (the Asian tiger mosquito) in the Torres Strait Islands (TSI) of Australia. We sampled mosquitoes from 13 TSI villages simultaneously and genotyped 373 mosquitoes at genome-wide single nucleotide polymorphisms (SNPs) 331 from the TSI, 36 from Papua New Guinea (PNG) and four incursive mosquitoes detected in uninvaded regions. Within villages, spatial genetic structure varied substantially but overall displayed isolation by distance and a neighbourhood size of 232-577. Close kin dyads revealed recent movement between islands 31-203 km apart, and deep learning inferences showed incursive Ae. albopictus had travelled to uninvaded regions from both adjacent and nonadjacent islands. Private alleles and a co-ancestry matrix indicated direct gene flow from PNG into nearby islands. Outlier analyses also detected four linked alleles introgressed from PNG, with the alleles surrounding 12 resistance-associated cytochrome P450 genes. By treating dispersal as both an intergenerational process and a set of discrete events, we describe a highly interconnected invasive system.
Oral sucrosomial iron (SI) combines enhanced bioavailability and tolerance compared to conventional oral iron along with similar efficacy compared to intravenous iron in several conditions associated with iron deficiency (ID).

In this non-randomized, open-label study, we sought to evaluate prospectively the effects of SI on clinical parameters, exercise capacity and quality of life in 25 patients with heart failure (HF) with reduced ejection fraction (HFrEF) and ID, treated with SI 28 mg daily for 3months, in comparison to 25 matched HFrEF controls. All patients were on optimal stable HF therapy. Patients were followed for 6months for death or worsening HF episodes. There were no differences in baseline characteristics between groups. At 3months, SI was associated with a significant increase in haemoglobin, serum iron and serum ferritin levels (all P≤ 0.001) along with a significant improvement in 6-min walked distance and Kansas City Cardiomyopathy Questionnaire (all P< 0.01), even after adjustment for baseline parameters; these differences persisted at 6months. Over the study period, there were no deaths, while 10 patients (20%) in total (four in the SI group and six in the control group), experienced worsening HF (odds ratio 0.51, 95% confidence interval 0.41-6.79, P= 0.482). Drug-associated diarrhoea was reported by one patient in the SI group and led to drug discontinuation; no other adverse events were reported.

In this proof-of-concept study, SI was well tolerated and improved exercise capacity and quality of life in HFrEF patients with ID. Randomized studies are required to further investigate the effects of this therapy.

Schizophrenia (SCZ) is a serious psychiatric disorder. Metabolite disturbance is an important pathogenic factor in schizophrenic patients. In this study, we aim to identify plasma lipid and amino acid biomarkers for SCZ using targeted metabolomics.

Plasma from 76 SCZ patients and 50 matched controls were analyzed using the LC/MS-based multiple reaction monitoring (MRM) metabolomics approach. A total of 182 targeted metabolites, including 22 amino acids and 160 lipids or lipid-related metabolites were observed. We used binary logistic regression analysis to determine whether the lipid and amino acid biomarkers could discriminate SCZ patients from controls. The area under the curve (AUC) from receiver operation characteristic (ROC) curve analysis was conducted to evaluate the diagnostic performance of the biomarkers panel.

We identified 19 significantly differentially expressed metabolites between the SCZ patients and the controls (false discovery rate < 0.05), including one amino acid and 18 lipids or lipid-related metabolites. The binary logistic regression-selected panel showed good diagnostic performance in the drug-naïve group (AUC = 0.936) and all SCZ patients (AUC = 0.948), especially in the drug-treated group (AUC = 0.963).

Plasma lipids and amino acids showed significant dysregulation in SCZ, which could effectively discriminate SCZ patients from controls. The LC/MS/MS-based approach provides reliable data for the objective diagnosis of SCZ.

For those who yearn to create a family despite these circumstances, assisted reproductive technology (ART) is an often-utilised resource. Though faith-based institutions have been referenced as a source of support for involuntarily childless adults, it is unclear how religious doctrine, especially that which prizes 'traditional' gender roles and genetic parenthood, may be a catalyst for distress. More research is needed to understand how the socio-cultural environment affects those who are unable to conceive without assistance. Therefore, the purpose of this research study was to understand the lived experiences of women who have utilised assisted reproduction in a particularly pronatalist, religious cultural context in the United States. From March to September 2017, in-depth interviews were conducted with 10 cisgender women who had utilised ART. Daty as such, in counselling would be beneficial.
To develop a robust, accurate, and accelerated T
quantification solution for submillimeter in vivo whole-brain imaging.

A multislice T
mapping solution (MS-T
) was developed based on a two-acquisition scheme using turbo spin echo with RF cycling to allow for whole-brain coverage with 0.8-mm in-plane resolution. A compressed sensing-based fast imaging method, SCOPE, was used to accelerate the MS-T
acquisition time to a total scan time of 3 minutes 31 seconds. A phantom experiment was conducted to assess the accuracy of MS-T
by comparing the T
value obtained using MS-T
with the reference value obtained using the standard single-slice T
mapping method. In vivo scans of 13 volunteers were acquired prospectively to validate the robustness of MS-T
.

In the phantom study, the T
values obtained with MS-T
were in good agreement with the reference T
values (R
= 0.9991) and showed high consistency throughout all slices (coefficient of variation = 2.2 ± 2.43%). In the in vivo experiments, T
maps were successfully acquired for all volunteers with no visually noticeable artifacts. There was no significant difference in T
values between MS-T
acquisitions and fully sampled acquisitions for all brain tissues (p-value > .05). In the intraclass correlation coefficient and Bland-Altman analyses, the accelerated T
measurements show moderate to good agreement to the fully sampled reference values.

The proposed MS-T
solution allows for high-resolution whole-brain T
mapping within 4 minutes and may provide a potential tool for investigating neural diseases.

Here, we investigated naturally-occurring variation in DNA methylation in a wild avian species, the white-throated sparrow (Zonotrichia albicollis). This species offers exceptional opportunities for studying the link between genetic differentiation and phenotypic traits because of a nonrecombining chromosome pair linked to both plumage and behavioural phenotypes. Using novel single-nucleotide resolution methylation maps and gene expression data, we show that DNA methylation and the expression of DNA methyltransferases are significantly higher in adults than in nestlings. Genes for which DNA methylation varied between nestlings and adults were implicated in development and cell differentiation and were located throughout the genome. In contrast, differential methylation between plumage morphs was concentrated in the nonrecombining chromosome pair. Interestingly, a large number of CpGs on the nonrecombining chromosome, localized to transposable elements, have undergone dramatic loss of DNA methylation since the split of the ZAL2 and ZAL2m chromosomes. Changes in methylation predicted changes in gene expression for both chromosomes. In summary, we demonstrate changes in genome-wide DNA methylation that are associated with development and with specific functional categories of genes in white-throated sparrows. Moreover, we observe substantial DNA methylation reprogramming associated with the suppression of recombination, with implications for genome integrity and gene expression divergence. These results offer an unprecedented view of ongoing epigenetic reprogramming in a wild population.
The population with intellectual disabilities (ID) has been reported to be a vulnerable population in terms of oral health. The aims of this study were to evaluate the oral condition and treatment needs of Special Olympics (SO) athletes from Greece, Italy and Spain.

A cross-sectional study was performed with data collected in annual SO events held in Greece, Italy and Spain, between 2010 and 2012. The recorded parameters were the presence/absence of edentulism, untreated decay, filled or missing teeth, sealants, tooth injury and signs of gingival disease. Among the main findings, the prevalence of untreated decay was 57.0% in Greece, 48.8% in Italy and 41.7% of the Spanish athletes. The prevalence of signs of gingival disease was 61.1% in Greece, 60.6% in Italy and 66.1% in Spain. While the majority of the athletes were in need of dental treatment.

Oral disease is an unresolved problem among athletes with ID in these Mediterranean countries. Therefore efforts should be directed to meet their treatment needs and to prevent oral disease.

To investigate the amplitude and spatial distribution of errors in wall shear stress (WSS) values derived from 4D flow measurements caused by displacement artifacts intrinsic to the 4D flow acquisition.

Phase-contrast MRI velocimetry was performed in a model of a stenotic aorta using two different timing schemes, both of which are commonly applied in vivo but differ in their resulting displacement artifacts. Whereas one scheme is optimized to minimize the duration of the encoding gradients (herein called FAST), the other aims to specifically minimize displacement artifacts by synchronizing all three spatial-encoding time points (called ECHO). WSS estimates were calculated and compared to unbiased WSS values obtained by a 5-hour single-point imaging acquisition. In addition, MRI simulations based on computational fluid dynamics data were carried out to investigate the impact of gradient timings corresponding to different spatial resolutions.

4D flow displacement artifacts were found to have an impact on , particularly when conducting inter-site studies or studies between vendors. The timing scheme should thus be explicitly mentioned in publications.
4D flow displacement artifacts can significantly impact the WSS estimates and depend on the timing scheme as well as potentially the image orientation. Whereas FAST might allow correct WSS estimation for lower resolutions, ECHO is recommended especially when spatial resolutions of 1 mm and smaller are used. Users need to be aware of this nonnegligible effect, particularly when conducting inter-site studies or studies between vendors. The timing scheme should thus be explicitly mentioned in publications.Italy is one of the countries on track with the WHO's agenda to eliminate hepatitis C virus (HCV) by 2030. Healthcare facilities play a crucial role in seeking patients who are infected but have not yet been treated. We assessed the effectiveness of a recall strategy, named 'Telepass' project, for patients exposed to HCV infection who have not yet been linked to care in a large tertiary care centre. The 'Telepass' project was structured in two phases (a) a retrospective analysis first identified all anti-HCV-positive subjects among patients who underwent pre-operative assessment in the facility in the course of one year; (b) a following prospective phase, aimed to recall patients in need either of further diagnostic tests (ie HCV-RNA) or treatment. A total of 12246 records of patients tested for HCV antibodies were reviewed. The overall prevalence of anti-HCV-positive subjects was 1.83% (224/12246) with a male/female ratio of 2.07. Out of the 224 anti-HCV-positive patients, 123 (54.91%) did not have documented HCV-RNA tests and were therefore selected for recall. Of these, 123 were reachable and 26 (21.13%) were successfully linked to care. Ten patients (38.46%) tested HCV-RNA positive and initiated treatment with direct-acting antivirals (DAAs). The Telepass study highlights that a recall strategy starting from internal hospital databases can help identify patients with chronic HCV infection who have not yet been linked to care, and provides an epidemiological insight into the prevalence of HCV infection in Italy in the late DAAs era.Many studies have assessed the potential of agricultural practices to sequester carbon (C). A comprehensive evaluation of impacts of agricultural practices requires not only considering C storage but also direct and indirect emissions of greenhouse gases (GHG) and their side effects (e.g., on the water cycle or agricultural production). We used a high-resolution modeling approach with the Simulateur mulTIdisciplinaire pour les Cultures Standard soil-crop model to quantify soil organic C (SOC) storage potential, GHG balance, biomass production and nitrogen- and water-related impacts for all arable land in France for current cropping systems (baseline scenario) and three mitigation scenarios (i) spatial and temporal expansion of cover crops, (ii) spatial insertion and temporal extension of temporary grasslands (two sub-scenarios) and (iii) improved recycling of organic resources as fertilizer. In the baseline scenario, SOC decreased slightly over 30 years in crop-only rotations but increased significantly in crop/temporary grassland rotations. Results highlighted a strong trade-off between the storage rate per unit area (kg C ha-1 year-1 ) of mitigation scenarios and the areas to which they could be applied. As a result, while the most promising scenario at the field scale was the insertion of temporary grassland (+466 kg C ha-1 year-1 stored to a depth of 0.3 m compared to the baseline, on 0.68 Mha), at the national scale, it was by far the expansion of cover crops (+131 kg C ha-1 year-1 , on 17.62 Mha). Side effects on crop production, water irrigation and nitrogen emissions varied greatly depending on the scenario and production situation. At the national scale, combining the three mitigation scenarios could mitigate GHG emissions of current cropping systems by 54% (-11.2 from the current 20.5 Mt CO2 e year-1 ), but the remaining emissions would still lie far from the objective of C-neutral agriculture.
Neutropenia is an adverse effect of vincristine when used in multidrug chemotherapy protocols.

To determine the incidence of neutropenia, identify potential risk factors for neutropenia, and determine the effect of neutropenia on outcome, in dogs receiving vincristine for treatment of immune-mediated thrombocytopenia (ITP).

One hundred twenty-seven client-owned dogs presumptively diagnosed with ITP.

In this retrospective cohort study, medical records were reviewed to identify dogs presumptively diagnosed with ITP, and treated with vincristine, over a 15-year period. Logistic regression was used to identify risk factors for the development of neutropenia in dogs receiving vincristine. Time to platelet count ≥40 000 platelets/μL, survival, and duration of hospitalization were compared between neutropenic and non-neutropenic dogs.

Vincristine was administered to 127 dogs with presumptive ITP; 19 became neutropenic. Administration of cyclosporine was significantly (P < .001) associated with the develceiving vincristine treatment for ITP, particularly if administered in conjunction with cyclosporine.Genes involved in the homologous recombination repair pathway-as exemplified by BRCA1, BRCA2, PALB2, ATM, and CHEK2-are frequently associated with hereditary breast and ovarian cancer syndrome. Germline mutations in the loci of these genes with loss of heterozygosity or additional somatic truncation at the WT allele lead to the development of breast cancers with characteristic clinicopathological features and prominent genomic features of homologous recombination deficiency, otherwise referred to as "BRCAness." Although clinical genetic testing for these and other genes has increased the chances of identifying pathogenic variants, there has also been an increase in the prevalence of variants of uncertain significance, which poses a challenge to patient care because of the difficulties associated with making further clinical decisions. To overcome this challenge, we sought to develop a methodology to reclassify the pathogenicity of these unknown variants using statistical modeling of BRCAness. The model was developed with Lasso logistic regression by comparing 116 genomic attributes derived from 37 BRCA1/2 biallelic mutant and 32 homologous recombination-quiescent breast cancer exomes. The model showed 95.8% and 86.7% accuracies in the training cohort and The Cancer Genome Atlas validation cohort, respectively. Through application of the model for variant reclassification of homologous recombination-associated hereditary breast and ovarian cancer causal genes and further assessment with clinicopathological features, we finally identified one likely pathogenic and five likely benign variants. As such, the BRCAness model developed from the tumor exome was robust and provided a reasonable basis for variant reclassification.Endemics co-occur because they evolved in situ and persist regionally or because they evolved ex situ and later dispersed to shared habitats, generating evolutionary or ecological endemicity centres, respectively. We investigate whether different endemicity centres can intertwine in the region ranging from Alps to Sicily, by studying their butterfly fauna. We gathered an extensive occurrence data set for butterflies of the study area (27,123 records, 269 species, in cells of 0.5 × 0.5 degrees of latitude-longitude). We applied molecular-based delimitation methods (GMYC model) to 26,557 cytochrome c oxidase subunit 1 (COI) sequences of Western Palearctic butterflies. We identified entities based on molecular delimitations and/or the checklist of European butterflies and objectively attributed occurrences to their most probable entity. We obtained a zoogeographic regionalisation based on the 69 endemics of the area. Using phylogenetic ANOVA we tested if endemics from different centres differ from each other and from nonendemics for key ecological traits and divergence time.
