To determine whether alcohol use disorder (AUD) is associated with increased dementia risk among older women veterans.

Cohort study.

United States.

Women veterans with AUD aged≥55years (n=2207), receiving care from Veterans Health Administration medical centers from October 2004 to September 2015 with one or more follow-up visit and an age-matched sample of women veterans without AUD (n=2207). Women at baseline with prevalent dementia or AUD in remission were excluded.

AUD, substance use disorder (SUD), smoking, psychiatric (depression, anxiety, post-traumatic stress disorder, anxiety) and medical comorbidities (diabetes, hypertension, stroke, chronic obstructive pulmonary disorder, traumatic brain disorder) and dementia determined by the International Classification of Diseases, 9th revision, Clinical Modification codes. Cox proportional hazards models were used to determine the association between AUD and dementia risk during follow-up. Sensitivity analyses were performed by excluding women (n=349) with comorbid SUD and by excluding women (n=1568) currently smoking.

Veteran women had a mean [standard deviation (SD)] age of 65.0 (5.6) years at baseline. During follow-up (median 4years, interquartile range 2-6) 3.7% of women (n=82) with AUD developed dementia compared with 1.1% (n=24) without AUD (P<0.001). After adjustment for demographics, medical and psychiatric conditions and accounting for different Veteran's Integrated Service Networks, the adjusted hazard ratio (aHR) for dementia was 3.12 (95% CI=1.90-5.12) for women with AUD compared with women without AUD. After removing women with SUD (aHR=3.53, 95% CI=2.13-5.85) and women currently smoking (aHR=3.80, 95% CI=2.11-6.84), results were similar.

Alcohol use disorder among female US veterans aged more than 55years appears to be associated with a more than threefold increase of dementia.

Unfortunately, the literature on relational teletherapy is not well developed. link= Selleckchem Ipatasertib This study sought to understand experiences of teletherapy with couples and families as it contrasts with individual clients and in-person therapy. We utilized a hermeneutic phenomenological approach to qualitative inquiry from data collected through open-ended questions on a web-based survey of graduate student trainees (n = 66) in COAMFTE-accredited couple and family therapy programs. Thematic analysis identified the body-of-the-therapist and client as they exist (and are obstructed) due to technology for creating barriers and opportunities in translating CFT intervention to telehealth platforms. Relational teletherapy cultivated therapist creativity and exhaustion. It also made plain the need for systemic interventions with children and adolescents that engages their parents and home environments. Implications for CFT practice, training, and intervention research are outlined.

Parkinson´s disease (PD) has a large phenotypic variability, which may, at least partly, be genetically driven including alterations of gene products. Candidates might not only be proteins associated with disease risk but also pathways that play a role in aging.

To evaluate phenotype-modifying effects of genetic variants in Klotho, a longevity gene.

We analyzed two longitudinal cohorts one local cohort comprising 459 PD patients who underwent genotyping for the KL-VS haplotype in Klotho including a subgroup of 125 PD patients and 50 healthy controls who underwent biochemical cerebrospinal fluid (CSF) analyses of Klotho and fibroblast growth factor 23 as well as vitamin D metabolites. The second cohort comprised 297 patients from the Parkinson's Progression Markers Initiative (PPMI) for validation of genetic-clinical findings.

PD patients carrying the KL-VS haplotype demonstrated a shorter interval between PD onset and onset of cognitive impairment (both cohorts) and higher Unified Parkinson´s Disease Rating Scale part III (UPDRS III) scores (PPMI). Selleckchem Ipatasertib CSF protein levels of Klotho and fibroblast growth factor 23 were lower in PD patients irrespective of gender compared to controls. Moreover, low CSF levels of Klotho were associated with higher scores in the UPDRS III and Hoehn and Yahr Scale.

Our results indicate that genetic variants in Klotho together with its corresponding CSF protein profiles are associated with aspects of disease severity in PD. link2 These findings suggest that pathways associated with aging might be targets for future biomarker research in PD.

Genetic programs underlying preimplantation development and early lineage segregation are highly conserved across mammals. It has been suggested that nonhuman primates would be better model organisms for human embryogenesis, but a limited number of studies have investigated the monkey preimplantation development. In this study, we collect single cells from cynomolgus monkey preimplantation embryos for transcriptome profiling and compare with single-cell RNA-seq data derived from human and mouse embryos.

By weighted gene-coexpression network analysis, we found that cynomolgus gene networks have greater conservation with human embryos including a greater number of conserved hub genes than that of mouse embryos. Consistently, we found that early ICM/TE lineage-segregating genes in monkeys exhibit greater similarity with human when compared to mouse, so are the genes in signaling pathways such as LRP1 and TCF7 involving in WNT pathway. Last, we tested the role of one conserved pre-EGA hub gene, SIN3A, using a morpholino knockdown of maternal RNA transcripts in monkey embryos followed by single-cell RNA-seq. link3 We found that SIN3A knockdown disrupts the gene-silencing program during the embryonic genome activation transition and results in developmental delay of cynomolgus embryos.

Taken together, our study provided new insight into evolutionarily conserved and divergent transcriptome dynamics during mammalian preimplantation development.

Yet a thorough, quantitative investigation of how available standardized and study-specific T1-weighted templates perform in studies on older adults has not been conducted. The purpose of this work was to construct a high-quality standardized T1-weighted template specifically designed for the older adult brain, and systematically compare the new template to several other standardized and study-specific templates in terms of image quality, performance in spatial normalization of older adult data and detection of small inter-group morphometric differences, and representativeness of the older adult brain. The new template was constructed with state-of-the-art spatial normalization of high-quality data from 222 older adults. It was shown that the new template (a) exhibited high image sharpness, (b) provided higher inter-subject spatial normalization accuracy and (c) allowed detection of smaller inter-group morphometric differences compared to other standardized templates, (d) had similar performance to that of study-specific templates constructed with the same methodology, and (e) was highly representative of the older adult brain.

The aim of this study was to investigate if intramuscular injection of sterile water can be used as a human experimental pain model that resembles clinical craniofacial muscle pain and to analyse if the effects differ between sexes.

This randomised, double-blind, placebo-controlled cross-over study included 30 healthy age-matched women and men (23.6±2.4years). link2 At three sessions, with at least one week of washout in between, 0.2mL of either sterile water (test-substance), hypertonic saline (58.5mg/mL; active control) or isotonic saline (0.9mg/mL; passive control) was randomly injected into the right masseter muscle. link3 Pain intensity (VAS) was continuously assessed during 5min whereafter pain duration (s) and pain area (au) were calculated; pressure pain thresholds (PPT;kPa) were recorded every 5minutes during 30minutes.

Sterile water evoked pain of similar intensity (74.5±49.9) as hypertonic saline (74.0±50.5); whereas, isotonic saline evoked low-intensity pain (11.4±23.4). The pain induced by sterile water and hypertonic saline had higher intensity (P<0.001), longer duration (P<0.001) and larger pain area (P<0.001) than isotonic saline. There were no significant differences in any pain variable between sterile water and hypertonic saline. Selleckchem Ipatasertib The PPT did not change significantly after any substance, except for in women 5minutes after sterile water injection (P<0.002). Pain duration was longer in the men for all substances (P<0.006), while the pain area was larger in women after injection of hypertonic saline (P<0.003).

These results indicate that pain evoked by sterile water resembles clinical muscle pain and may offer a novel and simpler alternative to hypertonic saline injections.

The AFP model, which is currently used in France to select LT candidates, was derived from a cohort of LT performed between 1988 and 2001, including a majority of HCV-positive recipients. The emergence of new direct-acting antiviral therapies and subsequent decrease of HCV incidence may change the generalizability of such models. We performed an external validation of the AFP model in a cohort of recipients transplanted between 2005 and 2018. Although multivariable analysis identified all three model's factors (AFP level, largest tumor size, number of nodules) as predictors of tumor recurrence, the AFP model showed poor discrimination and calibration in the present cohort. This poor performance could be related to significant differences between the derivation and the present cohort in terms of etiology, severity of underlying liver disease, tumor burden and differentiation, and use of neoadjuvant treatments. The present findings suggest that the decline of HCV-induced HCC among LT candidates may compromise the generalizability of the AFP model in more recent LT cohorts. Further studies are required for updating or building more robust prognostic models.
