Training Students Through a Community Outreach Program to Support Families of Children with Autism Spectrum Disorder

This outreach program involved training eight graduate and 19 undergraduate students to create evidence-based communication supports for families of children with autism spectrum disorder (ASD) within the context of a two-course sequence on ASD. During the training program, ten families in rural Appalachia benefited from our services. Student and family satisfaction data with the outreach program was highly positive. Undergraduate and graduate university students participating in the program met or partially met 97% of their goals set at the beginning of each semester. Undergraduate students’ self-ratings of their own knowledge about material covered in the course were significantly higher than their confidence in applying their knowledge about the materials. Thematic analyses of students’ comments about their experiences revealed that the hands-on experience and opportunities to create materials and collaborate with each other were among the aspects of the program they liked most. The value of outreach programs to foster training of undergraduate and graduate students through community connections will be discussed

The relationship between chronic diseases and number of sexual partners: an exploratory analysis

Background: We investigated sex-specific associations between lifetime number of sexual partners and several health outcomes in a large sample of older adults in England. Methods: We used cross-sectional data from 2,537 men and 3,185 women aged ≥50 years participating in the English Longitudinal Study of Ageing. Participants reported the number of sexual partners they had had in their lifetime. Outcomes were self-rated health and self-reported limiting long-standing illness, cancer, coronary heart disease (CHD), and stroke. We used logistic regression to analyse associations between lifetime number of sexual partners and health outcomes, adjusted for relevant sociodemographic and health-related covariates. Results: Having had 10 or more lifetime sexual partners was associated with higher odds of reporting a diagnosis of cancer than having had 0-1 sexual partners in men (OR=1.69, 95% CI 1.01-2.83) and women (OR=1.91, 95% CI 1.04-3.51), respectively. Women who had 10 or more lifetime sexual partners also had higher odds of reporting a limiting long-standing illness (OR=1.64, 95% CI 1.15 2.35). No other statistically significant associations were observed. Conclusions: A higher lifetime number of sexual partners is associated with increased odds of reported cancer. Longitudinal research is required to establish causality. Understanding the predictive value of lifetime number of sexual partner as a behavioural risk factor may improve clinical assessment of cancer risk in older adults

Associations between sexual activity and weight status: Findings from the English Longitudinal Study of Ageing.

OBJECTIVE: To investigate the association between weight status and sexual activity in middle-aged and older adults. METHODS: Cross-sectional analysis on Wave 6 (2012/13) of the English Longitudinal Study of Ageing. Data were from 2,200 men and 2,737 women aged ≥50 years (mean 68.2 years). The explanatory variable was weight status, defined as normal-weight (BMI: ≤24.9), overweight (BMI: 25.0-29.9) or obese (BMI: ≥30) based on objective measurements of height and weight. Outcome variables were any self-reported sexual activity in the last year (yes/no) and, if yes, frequency of sexual intercourse in the last month. Covariates included a range of sociodemographic, lifestyle, and health-related variables. Associations were analysed using binary (past-year sexual activity) and ordinal (frequency of past-month sexual intercourse) logistic regression models. RESULTS: The majority (73.3%) of men and half (50.0%) of women reported any sexual activity in the last year. The odds of reporting any sexual activity in the last year did not differ significantly by weight status in either men or women. However, among those who were sexually active, men with overweight (OR = 1.45, 95% CI 1.15-1.81, p = 0.002) or obesity (OR = 1.38, 95% CI 1.07-1.77, p = 0.015), and women with overweight (OR = 1.34, 95% CI 1.05-1.71, p = 0.017) reported significantly more frequent sexual intercourse in the last month compared with those who had a BMI in the normal-weight range, after adjustment for covariates. CONCLUSION: Older adults with overweight or obesity who are sexually active engage in more frequent sexual activity than those who are normal weight

Common and heritable components of white matter microstructure predict cognitive function at 1 and 2 y

The integrity or microstructure of white matter as determined by diffusion tensor imaging (DTI) is related to cognitive function. Most studies focus on individual tracts, even though the microstructure of white matter tracts throughout the brain is highly correlated. In older adults, a common property of white matter predicts cognitive function, though it is not known if common factors are present in early childhood development or how they relate to cognitive function. Here, we found that DTI-based common underlying factors that emerge at this age are significantly related to cognitive abilities from birth to age 2 y. These findings indicate that the functional specialization of cognition and the anatomical differentiation of fibers cooccur in the neonatal and infant brain

Harnessing the gatekeepers of glucocorticoids for chemoprevention of non-melanoma skin cancer

Despite effective surgical methods for non-melanoma skin cancer (NMSC), patients suffer from tissue damage, scarring, or even disfigurement; thus, there is a need for chemopreventive approaches. Because of the complex interplay between glucocorticoids (GCs), inflammation, and cancer, we sought to determine the role of 11β-hydroxysteroid dehydrogenase 1 and 2 (11βHSD1 and 2) in regulating GCs during skin cancer development and progression. 11βHSDs modulate the activation of GCs in a tissue-specific manner and have been reported to play a role in development and progression of other types of cancer, but their role has not yet been reported in NMSC. Here, we found a significant upregulation of 11βHSD2 protein in skin cancer cells when compared to normal skin cells, suggesting a role for this enzyme in the multifactorial process of skin cancer development. In addition, inhibition of 11βHSD2 with siRNA resulted in significant reduction in colony formation in vitro. Finally, our in vivo study elucidated that inhibition of 11βHSD2 with pharmacological inhibitor, Glycyrrhetinic acid (GA) could significantly diminish tumorigenesis in a well-studied in vivo mouse model of NMSC. Overall, these studies highlight for the first time a potential novel role for 11βHSD2 in NMSC development and may allow for new GC treatment approaches capable of avoiding deactivation by the enzyme. If 11βHSD2 can be inhibited as we have done here, or circumvented using modified GCs, this may lead to more efficacious outcomes for NMSC patients by preventing deactivation of the GC and minimizing resistance

Sarcopenia in autoimmune and rheumatic diseases: a comprehensive review

Sarcopenia refers to a decrease in skeletal muscle mass and function. Because sarcopenia affects mortality, and causes significant disability, the clinical importance of sarcopenia is emerging. At first, sarcopenia was recognized as an age-related disease but, recently, it has been reported to be prevalent also in younger patients with autoimmune diseases. Specifically, the association of sarcopenia and autoimmune diseases such as rheumatoid arthritis has been studied in detail. Although the pathogenesis of sarcopenia in autoimmune diseases has not been elucidated, chronic inflammation is believed to contribute to sarcopenia, and moreover the pathogenesis seems to be different depending on the respective underlying disease. The definition of sarcopenia differs among studies, which limits direct comparisons. Therefore, in this review, we cover various definitions of sarcopenia used in previous studies and highlight the prevalence of sarcopenia in diverse autoimmune diseases including rheumatoid arthritis, spondyloarthritis, systemic sclerosis, inflammatory bowel disease, and autoimmune diabetes. In addition, we cover the pathogenesis and treatment of sarcopenia in autoimmune and rheumatic diseases. This review provides a comprehensive understanding of sarcopenia in various autoimmune diseases and highlights the need for a consistent definition of sarcopenia

Substituted N -(Biphenyl-4′-yl)methyl ( R )-2-Acetamido-3-methoxypropionamides: Potent Anticonvulsants That Affect Frequency (Use) Dependence and Slow Inactivation of Sodium Channels

We prepared 13 derivatives of N-(biphenyl-4′-yl)methyl (R)-2-acetamido-3-methoxypropionamide that differed in type and placement of a R-substituent in the terminal aryl unit. We demonstrated that the R-substituent impacted the compound’s whole animal and cellular pharmacological activities. In rodents, select compounds exhibited excellent anticonvulsant activities and protective indices (PI = TD50/ED50) that compared favorably with clinical antiseizure drugs. Compounds with a polar, aprotic R-substituent potently promoted Na+ channel slow inactivation and displayed frequency (use) inhibition of Na+ currents at low micromolar concentrations. The possible advantage of affecting these two pathways to decrease neurological hyperexcitability is discussed

Isomeric iminofullerenes as acceptors in bulk heterojunction organic solar cells

Two stable iminofullerene isomers, [5,6]-open azafulleroid (open APCBM) and [6,6]-closed aziridinofullerene (closed APCBM) enable us to scrutinize the use of these new acceptors in polymer bulk heterojunction (BHJ) solar cells and compare the effects of open trans- and closed trans-annlar subunits. When we compared the performance of both isomer devices, the poly(3-hexylthiophene)(P3HT):open APCBM device demonstrates an enhancement in photocurrent in comparison with the P3HT: closed APCBM device. From the comparative study, we attribute the enhanced current to the lower degree of symmetry of open APCBM. The alteration of fullerene structure from closed to open breaks its high degree of symmetry and consequently leads to an improved bulk heterojunction with the electron donating conjugated polymer.close242

Sexual Activity is Associated with Greater Enjoyment of Life in Older Adults

Background: Relationships between sexual activity, problems and concerns and wellbeing among older adults have not been fully explored. Aim: To investigate associations between sexual activity, problems and concerns and experienced wellbeing in a representative sample of older adults. Methods: Cross-sectional analyses from the English Longitudinal Study of Ageing. Sexual behavior, problems and concerns were assessed by self-completion questionnaire. Covariates included age, partnership status, socio-economic status, smoking status, alcohol intake, limiting long-standing illness, and depressive symptoms. Data were analyzed using one-way independent analyses of variance. Main Outcome: Enjoyment of life was assessed with the pleasure subscale from CASP-19, a validated measure of quality of life specific to older age. Results: Data were available on sexual activity and enjoyment of life for a total of 3,045 men and 3,834 women (mean=64.4 in men, 65.3 in women). Men and women who reported any sexual activity in the past year had significantly higher mean enjoyment of life scores than those who were not sexually active (men=9.75 vs. 9.44, p<0.001, women=9.86 vs. 9.67, p=0.003). Among sexually active men, frequent (≥2 times a month) sexual intercourse (p<0.001) and frequent kissing, petting or fondling (p<0.001) were associated with greater enjoyment of life. Among sexually active women, frequent kissing, petting or fondling was also associated with greater enjoyment of life (p<0.001) but there was no significant association with frequent intercourse (p=0.101). Concerns about one’s sex life and problems with sexual function were strongly associated with lower levels of enjoyment of life in men, and to a lesser extent in women. Conclusion: This is among the first studies to show that wellbeing is higher among older adults when they are sexually active. Preferences regarding the expression of sexual activity differed between the sexes. Further longitudinal research is required in order to confirm a causal association between sexual activity and wellbeing
