1% vs 34.1%, P < 0.001). Propensity score matching produced 51 matched pairs, and the 3-year OS was still better in the NSM(+) compared with the NSM(-) group (66.7% vs 40.0%, P = 0.025). Multivariable Cox analysis confirmed NSM(+) as an independent factor favouring OS in patients with MT-OSCC.

NSM usually occurs at pN1 stage in patients with MT-OSCC, and is associated with a favourable prognosis.

This study investigated macrovascular and microcirculation changes and inflammatory markers during repetitive sleep restriction. Sex differences were also explored. Forty-five participants completed a 22-day in-hospital protocol. Participants were assigned to 1) Eight-hour sleep per night (control), or 2) Sleep restriction (SR) condition participants slept from 0300-0700 hours for three nights followed by a recovery night of 8-h sleep, repeated four times. Flow mediated dilation (FMD) and microcirculation reactivity tests were performed at baseline, last day of each experimental block and during recovery at the end. Cell adhesion molecules and inflammatory marker levels were measured in blood samples. No duration of deprivation (SR block) by condition interaction effects were found for FMD, microcirculation, norepinephrine, cell adhesion molecules, IL-6 or IL-8. However, when men and women were analyzed separately, there was a statistical trend (p=0.08) for increased IL-6 across SR blocks in women, but not in men. Interestingly, men showed a significant progressive (dose dependent) increase in skin vasodilatation (p=0.02). A novel and unexpected finding was that during the recovery period, men that had been exposed to repeated SR blocks had elevated IL-8 and decreased norepinephrine. Macrocirculation, microcirculation, cell adhesion molecules and markers of inflammation appeared to be resistant to this model of short-term repetitive exposures to the blocks of shortened sleep in healthy sleepers. However, men and women responded differently, with women showing mild inflammatory response and men showing more vascular system sensitivity to the repetitive SR.Optimal contributions approaches to parental selection in closed breeding populations aim to maximize genetic gains, while restraining long-term inbreeding. Compstatin Complement System inhibitor The adoption of optimal contribution selection (OCS) in highly fecund outcrossing species presents a number of challenges not applicable to species of low fecundity (e.g., livestock) for which they were developed. This is particularly true if overlapping-generations or rolling-front breeding strategies are applied, in which case the number of individuals per family in juvenile (i.e., sexually immature) age groups is not necessarily known but is likely to be large. In these circumstances, conventional OCS procedures must be modified or a large number of dummy individuals defined, making computations onerous. Here, an approach to OCS is presented that involves the use of "between-family relationship matrices" instead of "between-individual relationship matrices." The method is applicable to breeding programs involving highly fecund outcrossing species with overlapping generations, including circumstances where the number of juveniles per family is unknown but large.
The hands-on surgical training course utilizes 3-dimensional (3D)-printed heart models to simulate complex congenital heart operations. This study aimed to validate a model and assessment tool in the simulation of 2 techniques of the Norwood operation and investigate whether technical performance improves following rehearsal with or without proctor presence.

Five 'experienced' and 5 'junior' surgeons performed 2 techniques of the Norwood operation on 3D-printed models of hypoplastic left heart syndrome. Performances were retrospectively assessed by 10 raters with varying experience in congenital heart surgery (CHS) (Medical Doctorate versus non-Medical Doctorate). Assessments were made with the procedure-specific Hands-On Surgical Training-CHS tool. Results were analysed for technical performance and rater consistency. Following validation, 30 surgeons (24 with proctor guidance and 6 with training videos and objective feedback only) simulated the Norwood operation twice.

Performance scores were consisteRehearsal both under supervision and independently leads to technical skill improvement further supporting its value in CHS training.
Procedure-specific assessment tools can be developed to evaluate technical performance for complex CHS simulation and be performed reliably by non-expert raters. Rehearsal both under supervision and independently leads to technical skill improvement further supporting its value in CHS training.
Extraction of cardiovascular implantable electronic devices in low-volume medical centres with limited clinical experience and an evolving lead extraction programme may be challenging. We aimed to evaluate the safety and efficacy of stepwise transvenous lead extraction (TLE) using a novel type of hand-powered rotational sheath as a first-line tool for extraction of chronically implanted devices in a single, low-volume centre.

Sixty-seven consecutive patients undergoing a TLE procedure using the novel Evolution® RL rotational sheath as the first-line extraction tool between 2015 and 2019 at our institution were enrolled in the study. Their short-term and 30-day outcomes were observed.

Sixty-nine devices and 131 leads were explanted. Procedural and clinical success rates were 92.4% and 98.5%, respectively. Two procedures were classified as failures due to lead remnants >4 cm remaining in patients' vascular systems. One major (1.5%) and 3 minor (4.4%) adverse events and no deaths were observed.

TLE prvolving TLE programmes, a stepwise extraction strategy using the Evolution RL sheath by skilled operator may provide the optimal scheme with an excellent ratio between clinical and/or procedural success and complications.
Human cytochrome P450 24 subfamily A member 1 (CYP24A1) loss-of-function mutations result in impaired activity of the 24-hydroxylase involved in vitamin D catabolism, thus inducing a vitamin D-dependent hypercalcemia. Homozygotes often present an overt clinical phenotype named idiopathic infantile hypercalcemia (IIH), whereas it is debated whether heterozygotes display an abnormal phenotype.

To compare the clinical and biochemical features of heterozygous carriers of CYP24A1 variant and healthy wild-type controls sharing the same genetic and environmental exposure.

A large family harboring the nonsense c.667A>T, p.Arg223* pathogenic variant in the CYP24A1 gene was evaluated. All subjects underwent clinical and biochemical evaluation and complete analysis of vitamin D metabolites using mass spectroscopy including 1,24,25(OH)3D3. Subjects were divided into 2 groups according to their genotype heterozygotes and wild-type for the CYP24A1 variant.

The proband, a 40-year-old man, homozygous for p.Arg223*nce because of the potential risk of developing hypercalcemia and related clinical manifestations if exposed to triggering factors.
For the growing population of older immigrants in the United States, both age at immigration and familial relationships are important factors affecting psychological well-being. This study explores how age at immigration and contemporary relationships with adult children combine to explain older immigrants' depressive symptoms.

This study uses 2014 Health and Retirement Study data from a sample of 759 immigrants age 65 and older who have at least one adult child age 21 or older. A series of ordinary least squares regressions and mediational analyses were conducted.

Findings indicate that structural solidarity significantly mediates the association between age at immigration and depressive symptoms. Specifically, immigrating in later life was associated with a lower level of depressive symptoms through its relationship with structural solidarity. In addition, giving monetary support to children and providing care for grandchildren may alleviate depressive symptoms for older immigrants.

This study suggests that relationships with adult children may differ with age at immigration. The types of support that older immigrants provide to their adult children may be crucial because such support may instill a sense of obligation and reciprocity that may be beneficial to the psychological well-being of older immigrants.

Failure of glioblastoma (GBM) therapy is often ascribed to different types of glioblastoma stem-like cells (GSLCs) niche, in particularly, a hypoxic perivascular niche (HPVN) is involved in GBM progression. However, the responsible cells for HPVN remained unclear.

Immunostaining was performed to determine the cells that are responsible for HPVN. A hypoxic chamber and 3D microfluidic chips were designed to simulate HPVN based on the pathological features of GBM. The phenotype of GSLCs was evaluated by fluorescence scanning in real-time and proliferation and apoptotic assays. The expression of JAG1, DLL4 and Hes1 was determined by immunostaining, ELISA, western-blotting, and q-PCR. Their clinical progonostic significance in GBM HPVN and total tumor tissues were verified by clinical data and TCGA databases.

Nestin +/CD31 + cells and pericytes constitute the major part of microvessels in HPVN and high ratio of nestin +/CD31 + cells rather than pericytes were responsible for poor prognosis of GBM. A more real HPVN was simulated by hypoxic coculture system in vitro, which was assembled by 3D microfluidic chips and hypoxic chamber. Nestin +/CD31 + cells in HPVN were derived from GSLCs transdifferentiation and could promote GSLCs chemoresistance by providing more JAG1 and DLL4 to induce down-stream Hes1 overexpression. Poor prognosis of GBM was correlated to Hes1 expression of tumor cells in GBM HPVN, and not correlated with total Hes1 expression in GBM tissues.

These results hightlighted the critical role of nestin +/CD31 + cells in HPVN that acts in GBM chemoresistance and revealed the distinctive prognostic value of these molecular markers in HPVN.

Human papillomavirus (HPV) vaccination programs achieve substantial population-level impact, with effects extending beyond protection of vaccinated individuals. We assessed trends in HPV prevalence up to 8 years postvaccination among men and women in the Netherlands, where bivalent HPV vaccination, targeting HPV types 16/18, has been offered to (pre)adolescent girls since 2009 with moderate vaccination coverage.

We used data from the PASSYON study, a survey initiated in 2009 (prevaccination) and repeated biennially among 16- to 24-year-old visitors of sexual health centers. We studied genital HPV positivity from 2009 to 2017 among women, heterosexual men, and unvaccinated women using Poisson generalized estimating equation models, adjusted for individual- and population-level confounders. link2 Trends were studied for 25 HPV types detected by the SPF10-LiPA25 platform.

A total of 6354 women (64.7% self-reported unvaccinated) and 2414 heterosexual men were included. link3 Percentual declines in vaccine types HPV-16/18 were observed for all women (12.
