We conclude that phenotypic selection of individuals from the S1 population is feasible for improving fitness and stress resistance in novel inbred lines of tall fescue for development of new turf cultivars with the desired ecophysiological traits.Immune sensitization, defined as the presence of alloreactive donor-specific antibodies (DSA), is associated with increased wait-times and inferior transplant outcomes. Identifying pretransplant DSA with a physical cell-based assay is critical in defining immunological risk. However, improved solid phase antibody detection has provided the potential to forgo this physical assay. Here, we evaluated the association between DSA mean fluorescence intensity (MFI) and the recently introduced Halifaster Flow cytometry crossmatch (FXM) to determine if MFI could predict the outcome of FXM and whether a virtual crossmatch (VXM) would provide an accurate risk assessment. Sera from 134 waitlisted lung patients was retrospectively assessed by Halifaster FXM against lymphocytes preparations from 32 donors, resulting in 265 FXMs. HLA typing was performed to 2-field allelic level and Luminex single antigen beads (SAB) used to identify DSA. The association between FXM and Luminex MFI was calculated using ROC analysis. MFI threshold accuracy was confirmed using a separate validation cohort (174 recipient sera and 34 donors), whereby both VXM and FXMs were compared. From the 265 FXM performed, 48 (18%) T-cell (TFXM) and 56 (21%) B-cell (BFXM) were positive. In the evaluation cohort, MFI thresholds of 2000 for HLA-A, B, DRB1, and > 4000 for DQB1, were predictive of a positive FXM. The validation cohort of 233 paired FXM and VXM confirmed these MFI thresholds for both TFXM and BFXM with an accuracy of 91.4% and 89.3%, respectively. A positive VXM, defined with HLA-specific MFI thresholds predicts Halifaster FXM reactivity, and can potentially expedite organ allocation, by minimizing the need for the more time-consuming FXM.
Our objective was to describe and compare the occurrence of neurological outcomes and neurosyphilis in people living with HIV with incident syphilis and no neurological symptoms who underwent early screening for asymptomatic neurosyphilis (ANS) or regular clinical management without a lumbar puncture.

This was a retrospective cohort study in a single referral centre of Sao Paulo, Brazil. Patients with incident syphilis diagnosed between January 2000 and August 2016 and meeting the adapted criteria for ANS investigation suggested by Marra et al. (CD4
T-cell counts ≤350 cells/mm³ and/or venereal disease research laboratory test results ≥116) were identified. Those with no neurological symptoms and immediately referred for lumbar puncture were categorized as group 1, and those not referred for cerebrospinal fluid collection were categorized as group 2. We compared the occurrence of neurological symptoms and neurosyphilis diagnoses between the groups using incidence rates and Kaplan-Meier curves.

We included 425 participants with a median follow-up of 6years. The incidence rate of neurological symptoms was 36.5/1000 person-years in group 1 and 40.6/1000 person-years in group 2 (incidence rate ratio [IRR] 0.90; 95% confidence interval [CI] 0.57-1.39; p=0.62). The incidence rate of neurosyphilis was 15.0 cases/1000 person-years in group 1 and 6.7 cases/1000 person-years in group 2 (IRR 2.26; 95% CI 0.93-5.68; p=0.05).

We found no statistically significant differences between groups in the incidence rates of neurological symptoms and neurosyphilis. Our findings support the current guidelines, which suggest a less invasive approach regarding ANS investigation among people living with HIV with incident syphilis.

Itching is an irritating and uncomfortable sensation that has a profound effect on patients' physical and mental health. It is a major under-recognised problem in older patients who cannot express their pain due to advanced cognitive impairment. Therefore, objective itch-assessment tools that do not rely on patients' reports of itching may be of value for this patient group.

To summarise the characteristics of validated objective itch-assessment tools for patients with advanced cognitive impairment.

This scoping review was conducted according to the PRISMA extension for scoping reviews checklist. The PubMed, CINAHL and Cochrane Library databases were searched, via database-specific search strategies, for articles published in English between January 1, 1990 and March 11, 2020. Based on the eligibility criteria, two authors independently screened the articles for inclusion. Thereafter, the lead author performed data extraction and analysis.

Three validated scratch-monitoring using accelerometers and a ristics and validity of each objective itch-assessment tool and select the optimal tool for patients with advanced cognitive impairment who cannot express their discomfort caused due to itching.

Enteroviruses can cause severe infections, including viral myocarditis, meningitis, acute flaccid myelitis, and viral myositis.

We report a 3-year-old female renal transplant recipient who presented to a tertiary care hospital with elevated serum liver aminotransferases and subsequently developed proximal muscle pain, weakness, and respiratory distress during the first week of hospitalization. Imaging of the lower extremities revealed diffuse myositis of the proximal thigh and pelvic muscles. TEN010 A muscle biopsy was obtained and revealed necrotizing myositis with immunostaining positive for enterovirus, consistent with a diagnosis of enterovirus necrotizing myositis. She had complete resolution of symptoms with steroids, intravenous immune globulin, reduced tacrolimus dose, and physical therapy.

Enterovirus myositis should be included in the differential diagnosis for necrotizing myositis following renal transplantation in children.

Melasma is an acquired pigmentation disorder with a complex multifactorial etiopathogenesis. Oral tranexamic acid (TA) is a promising drug for its treatment and may enhance outcomes when used in combination.

To provide evidence of the efficacy and safety of oral TA as a monotherapy, and in combination with a triple combination cream, for treating melasma in the Hispanic population.

Forty-four female Hispanic patients with melasma were randomly assigned to receive 325mg of oral TA every 12h plus f-TCC (fluocinolone-based triple combination cream) every 24h (group A) or 325mg of oral TA every 12h (group B) for 8weeks, after which both groups were crossed-over, and treated for an additional 8weeks. Evaluations of the mMASI score, the melanin index, and the MelasQoL were made at baseline and Weeks 4, 8, 12, and 16.

There was a 50.04% and 65.45% improvement in mMASI at Weeks 4 and 8, respectively, in group A, compared to baseline, while for Week 16, an improvement of 76.85% was achieved in group B compared to baseline. Highest scores were consistent with the use of the combined treatment modality in both groups, and were evidenced by the values of the melanin index obtained. There was no significant difference in MelasQoL scores between the 2groups. No serious side effects were observed.

The combination of oral TA and f-TCC is more effective than oral TA alone in the treatment of severe melasma in Hispanic patients.

Infections with the zoonotic HEV genotype 3, which can be transmitted from infected wild boar and deer to humans, are increasingly detected in Europe. To investigate the spatiotemporal HEV infection dynamics in wild animal populations, a study involving 3572 samples of wild boar and three deer species from six different geographic areas in Germany over a 4-year period was conducted. The HEV-specific antibody detection rates increased between 2013-2014 and 2016-2017 in wild boar from 9.5% to 22.8%, and decreased in deer from 1.1% to 0.2%. At the same time, HEV-RNA detection rates increased in wild boar from 2.8% to 13.3% and in deer from 0.7% to 4.2%. Marked differences were recorded between the investigated areas, with constantly high detection rates in one area and new HEV introductions followed by increasing detection rates in others. Molecular typing identified HEV subtypes 3c, 3f, 3i and a putative new subtype related to Italian wild boar strains. In areas, where sufficient numbers of positive samples were available for further analysis, a specific subtype dominated over the whole observation period. Phylogenetic analysis confirmed the close relationship between strains from the same area and identified closely related human strains from Germany. The results suggest that the HEV infection dynamics in wild animals is dependent on the particular geographical area where area-specific dominant strains circulate over a long period. The virus can spread from wild boar, which represent the main wild animal reservoir, to deer, and generally from wild animals to humans.
Although millions or even billions of sperm are deposited in the female genital tract, only very few sperm reach the oocyte, and only one single spermatozoon will successfully fertilize. During the journey of the sperm within the female genital tract, the interactions between spermatozoa and fallopian tube are critical for sperm selection, sperm survival, and maintenance of sperm fertilizing capacity.

This review will provide a comprehensive overview of the latest findings regarding sperm transport and behavior of sperm within the oviduct, sperm selection in the oviduct, the formation of the sperm reservoir, and the release of sperm in the presence of the oocyte. It will primarily focus on recent novel insights on sperm-oviduct interactions, which have been obtained by cutting-edge technologies under in vivo or near in vivo conditions.

The comprehensive analysis of the findings to date will elucidate the complex molecular changes in the tubal epithelium, which are induced by the presence of the sperm and will highlight how the epithelial cells of this organ affect transport, behavior, and function of sperm. This knowledge is essential for scientists and clinicians involved in assisted reproductive technologies.
