People with disabilities have not been adequately represented in strengths-based research. This study is the first to examine strengths and positive influences of young children with fetal alcohol ...spectrum disorder (FASD). Thirty adoptive and relative caregivers of children with FASD reported their children's strengths and positive influences and completed measures on family functioning. Using a conversion mixed design, we described themes in strengths and influences, degree of caregiver positivity and relationships with child and family functioning. Caregivers reported wide-ranging strengths and positive influences. Frequency of adaptive strengths correlated with measures of family functioning, but thematic strengths and positive influences did not. Strengths and positive influences are distinct from measures of functioning and are not well captured in deficit-focused research.
Resident stem/progenitor cells within the secretory salivary glands offer a potential therapeutic resource for use in the regeneration of salivary glands needed to restore saliva production in ...patients with chronic xerostomia, or dry mouth. Methods were developed previously to isolate human stem/progenitor cells (hS/PCs) from major salivary glands (parotid/submandibular). Abundant minor salivary glands located in readily accessible locations in the oral cavity and lip could provide an additional valuable therapeutic resource. An advantage of this cell resource is that these minor glands about the size of grape seeds can be harvested from healthy donors using minimally invasive surgical procedures. The disadvantage of using minor glands is that they contain many fewer cells than do major glands, and thus harvested cells need to be expanded in the lab to create a therapeutic resource. While earlier work has described isolation of proliferative cell populations from minor salivary glands that could be used in regenerative medicine, most of these expanded cells possess properties of mesenchymal cells rather than the epithelial population that secretes salivary products.Here, we describe in detail our recently established methods to isolate and expand hS/PCs isolated from human labial minor salivary glands. Expanded hS/PC populations are epithelial assessed by their expression of epithelial progenitor markers K5 and K14. Like expandable cell populations previously isolated from the major salivary glands, these cells also express nuclear p63, consistent with their ability to be expanded after explant culture. When hS/PCs with these properties are encapsulated into a customized 3D biomimetic hyaluronic acid-based hydrogel, they will assemble into microstructures that retain some progenitor markers while also beginning to differentiate. The increased expression of secreted mucin MUC-7 was used to demonstrate differentiation and secretory potential in assembled hS/PC microstructures. Compared to hS/PCs from major glands, those from minor salivary glands tend to be more heterogeneous in early passage; thus, use of K5/K14/p63 as an early quality assessment tool is highly recommended. Additionally, hS/PCs from minor glands are sensitive to stress and if mishandled will demonstrate a stress response that leads to their transitioning to a flat, squamous cell-like appearance that is of limited utility in regenerative medicine applications. We conclude that properly handled hS/PCs from minor salivary glands represent a powerful new source of therapeutic cells for applications including treating patients with chronic xerostomia.
Abstract The Princeton Consensus (Expert Panel) Conference is a multispecialty collaborative tradition dedicated to optimizing sexual function and preserving cardiovascular health. The third ...Princeton Consensus met November 8 to 10, 2010, and had 2 primary objectives. The first objective focused on the evaluation and management of cardiovascular risk in men with erectile dysfunction (ED) and no known cardiovascular disease (CVD), with particular emphasis on identification of men with ED who may require additional cardiologic work-up. The second objective focused on reevaluation and modification of previous recommendations for evaluation of cardiac risk associated with sexual activity in men with known CVD. The Panel's recommendations build on those developed during the first and second Princeton Consensus Conferences, first emphasizing the use of exercise ability and stress testing to ensure that each man's cardiovascular health is consistent with the physical demands of sexual activity before prescribing treatment for ED, and second highlighting the link between ED and CVD, which may be asymptomatic and may benefit from cardiovascular risk reduction.
Antimicrobial-resistant (AMR) bacteria are a threat to public health as they can resist treatment and pass along genetic material that allows other bacteria to become drug-resistant. To assess ...foodborne AMR risk, the Codex Guidelines for Risk Analysis of Foodborne AMR provide a framework for risk profiles and risk assessments. Several elements of a risk profile may benefit from a scoping review (ScR). To contribute to a larger risk profile structured according to the Codex Guidelines, our objective was to conduct a ScR of the current state of knowledge on the distribution, frequency and concentrations of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in salmon and shrimp. Articles were identified via a comprehensive search of five bibliographic databases. Two reviewers screened titles and abstracts for relevance and characterised full-text articles with screening forms developed a priori. Sixteen relevant studies were identified. This review found that there is a lack of Canadian data regarding ESBL-producing Enterobacteriaceae in salmon and shrimp. However, ESBL- producing Escherichia coli, Klebsiella pneumoniae and other Enterobacteriaceae have been isolated in multiple regions with a history of exporting seafood to Canada. The literature described herein will support future decision-making on this issue as research/surveillance and subsequent assessments are currently lacking.
The super Pioneering High Energy Nuclear Interaction eXperiment (sPHENIX) at the Relativistic Heavy Ion Collider will perform high-precision measurements of jets and heavy flavor observables for a ...wide selection of nuclear collision systems, elucidating the microscopic nature of strongly interacting matter ranging from nucleons to the strongly coupled quark-gluon plasma. A prototype of the sPHENIX calorimeter system was tested at the Fermilab Test Beam Facility as experiment T-1044 in the spring of 2016. The electromagnetic calorimeter (EMCal) prototype is composed of scintillating fibers embedded in a mixture of tungsten powder and epoxy. The hadronic calorimeter (HCal) prototype is composed of tilted steel plates alternating with the plastic scintillator. Results of the test beam reveal the energy resolution for electrons in the EMCal is <inline-formula> <tex-math notation="LaTeX">2.8\%\oplus 15.5\%/\sqrt {E} </tex-math></inline-formula> and the energy resolution for hadrons in the combined EMCal plus HCal system is <inline-formula> <tex-math notation="LaTeX">13.5\%\oplus 64.9\%/\sqrt {E} </tex-math></inline-formula>. These results demonstrate that the performance of the proposed calorimeter system satisfies the sPHENIX specifications.
Background
Obesity is highly prevalent in African American women, especially those in the rural southern USA, resulting in persistent health disparities.
Objective
To test the effectiveness of an ...evidence‐based behavioural weight loss intervention delivered by community health advisors to African American women in the rural south.
Design and Methods
Overweight or obese African American women (30–70 years) from eight counties in Mississippi and Alabama participated in a 24‐month randomized controlled trial of an evidence‐based behavioural weight loss programme augmented with community strategies to support healthy lifestyles (Weight Loss Plus, N = 154) compared to the weight loss programme alone (Weight Loss Only, N = 255). This study reports on 6‐month outcomes on primary (weight change) and secondary (waist circumference, blood pressure, lipids, fasting blood glucose) outcomes, coinciding with the completion of the intensive weight loss phase.
Results
Weight Loss Only participants lost an average of 2.2 kg (P < 0.001). Weight Loss Plus participants lost an average of 3.2 kg (P < 0.001). The proportion of the total sample that lost at least 5% of their body weight was 27.1% with no difference between treatment groups. Similarly, we observed statistically significant reductions in blood pressure, waist circumference and triglycerides in each treatment group, with no statistical differences between groups.
Conclusion
Trained lay health staff and volunteers from the rural southern USA were able to deliver a translation of a high‐intensity behavioural intervention targeted to African American women, resulting in clinically meaningful weight loss and improvement in other metabolic outcomes in a significant proportion of participants.
Background
Few studies have investigated the partner's influence on risk factors such as alcohol consumption and depression during pregnancy. Partner substance use and lower relationship satisfaction ...predict higher maternal alcohol use and depressive symptoms. Because prenatal alcohol use and maternal depression affect infant outcomes, it is imperative to examine how the partner affects these maternal risk factors. The current study examined the effect of a latent construct of partner influence on maternal alcohol use and depressive symptoms, and the effects on infant development of these maternal factors.
Methods
Participants were 246 pregnant women from 2 sites in Western Ukraine from whom longitudinal data were collected as part of a multisite study. In the first trimester, mothers reported on relationship satisfaction, partner substance use, and socioeconomic status (SES). In the third trimester, they reported on alcohol use and depressive symptoms. Infants were assessed using the Bayley Scale of Infant Development (average age = 6.93 months). A latent construct titled partner influence was formed using partner substance use and measures of relationship satisfaction, including the frequency of quarreling, happiness in the relationship, and the ease of talking with the partner. Using structural equation modeling, a model was specified in which partner influence and SES predicted maternal alcohol use and depressive symptoms, which in turn predicted infant neurodevelopmental outcomes.
Results
Higher partner influence significantly predicted lower prenatal alcohol use and lower depressive symptoms, controlling for the effect of SES. Higher maternal prenatal alcohol use significantly predicted lower infant mental and psychomotor development. Maternal depressive symptoms did not predict infant development over and above the effect of alcohol use.
Conclusions
Partner influence is an important contributor to prenatal alcohol use and maternal depressive symptoms, over and above the effect of SES. The significant paths from prenatal alcohol exposure to infant neurodevelopmental outcomes underscore the importance of partner influence during pregnancy.
We used structural equation modeling to understand the influence of the partner on maternal prenatal alcohol use and depressive symptoms, and the effect of these prenatal risk factors on the infant at six months. Partner influence was a latent construct made up of three relationship variables and two partner substance use variables. Controlling for socioeconomic status, partner influence significantly predicted alcohol use and depressive symptoms during the third trimester. Further, higher alcohol use predicted lower infant development at six months.
B cell chronic lymphocytic leukemia (CLL) is characterized by an accumulation of mature, functionally incompetent B cells. Wnts are a large family of secreted glycoproteins involved in cell ...proliferation, differentiation, and oncogenesis. The classical Wnt signaling cascade inhibits the activity of the enzyme glycogen synthase kinase-3β, augmenting β-catenin translocation to the nucleus, and the transcription of target genes. Little is known about the potential roles of Wnt signaling in CLL. In this study, we quantified the gene expression profiles of the Wnt family, and their cognate frizzled (Fzd) receptors in primary CLL cells, and determined the role of Wnt signaling in promoting CLL cell survival. Wnt3, Wnt5b, Wnt6, Wnt10a, Wnt14, and Wnt16, as well as the Wnt receptor Fzd3, were highly expressed in CLL, compared with normal B cells. Three lines of evidence suggested that the Wnt signaling pathway was active in CLL. First, the Wnt/β-catenin-regulated transcription factor lymphoid-enhancing factor-1, and its downstream target cyclin D1, were overexpressed in CLL. Second, a pharmacological inhibitor of glycogen synthase kinase-3β, SB-216763, activated β-catenin-mediated transcription, and enhanced the survival of CLL lymphocytes. Third, Wnt/β-catenin signaling was diminished by an analog of a nonsteroidal antiinflammatory drug (R-etodolac), at concentrations that increased apoptosis of CLL cells. Taken together, these results indicate that Wnt signaling genes are overexpressed and are active in CLL. Uncontrolled Wnt signaling may contribute to the defect in apoptosis that characterizes this malignancy.
