The rural weekly newspaper industry rooted in traditional geographically bounded U.S. communities was long thought to have been shielded from industry dilemmas—revenue and circulation—at larger mainstream daily newspapers. However, recent data show a shift in these rural community journalism trends, particularly since the COVID-19 pandemic. Using normative theory and diffusion of innovations, this study examines how rural weekly newspaper publishers perceived, nearly 18 months after the onset of the pandemic, how COVID-19 impacted their newspapers' advertising, news, technology, and community involvement. Survey results reveal short-term and long-term content and financial challenges plague U.S. rural grassroots information sources with circulation less than 3,000—indicating the end of the "golden era" of weekly newspapers. Despite the constraints, publishers remain optimistic and dedicated to their audiences, albeit reluctant to swift change, as they perceive themselves as the only reliable information source for their rural communities.

Background: Nordic walking (NW) is a potentially beneficial exercise strategy for overweight and obese people. To date, no reviews have synthesized the existing scientific evidence regarding the effects of NW on this population. This systematic review and meta-analysis aimed to identify the characteristics, methodological quality, and results of the investigations that have studied the effects of NW in overweight and obese individuals. Methods: Six electronic databases were searched up to June 2019 for studies that examined the effects of NW on people with a body mass index ≥ 25 kg/m2. The methodological quality of the included randomized controlled trials was retrieved from the physiotherapy evidence database or evaluated using the physiotherapy evidence database scale. Results: Twelve studies were included in the review. The investigations were mostly good-to-fair methodological quality. NW groups had a significant improvement on parameters such as fasting plasma glucose, abdominal adiposity, and body fat compared with the baseline, but no significant improvements were found when compared with control groups. Conclusions: NW can potentially lead to improvements in parameters related to major health outcomes in overweight and obese people. The lack of control for confounding variables in the analyzed studies prevents further elaboration on its potential benefits. [ABSTRACT FROM AUTHOR]

Globally daily news podcasts have exponentially grown in popularity. To build on the increased interest in this podcast format, this study examines three distinct programmes in this genre. The focus of our research specifically highlights the significant news events during the summer of 2020: the killing of George Floyd, and subsequent Black Lives Matter protests, and the COVID-19 pandemic. Using a set of genre conventions adapted and expanded from previous podcast and radio news scholarship, this research analyses the impact podcasting has on daily audio news production. Our findings indicate the podcast host's empathy and intimacy, coalesced into powerful, immersive deep dive discussions. Those kinds of conversations have strongly influenced and transformed daily news production, while still maintaining journalistic ethics and aesthetics. [ABSTRACT FROM AUTHOR]

Social connections are crucial for an individual's health, wellbeing, and overall effective functioning. During the COVID-19 pandemic, one major preventative effort for reducing the spread of COVID-19 involved restricting people's typical social interactions through physical distancing and isolation. The current cross-sectional study, conducted during the COVID-19 pandemic, explored the relationship among fear of COVID-19, social connectedness, resilience, depressive symptomologies, and self-perceived stress. Participants (N = 174) completed an anonymous, online questionnaire, and results indicated that social connectedness mediated the relationship between fear of COVID-19 and psychological wellbeing. In contrast, the relationship between fear of COVID-19 and psychological wellbeing was not mediated by resilience. These findings highlight the important role that social connections and resilience play in buffering against negative psychological wellbeing outcomes, especially during a pandemic.

Two children with achondroplasia who developed an abnormal bony outgrowth at the distal radioulnar joint (DRUJ), indistinguishable from an osteochondroma on histology, but the radiographic appearance, location, and asymmetry suggested the rare diagnosis of dysplasia epiphysealis hemimelica (DEH or "Trevor's disease"). One child experienced symptomatic relief with surgical excision and one was observed clinically due to lack of significant symptoms. These are the first presented cases of DEH in achondroplasia, both affecting the DRUJ. Due to the infrequency of DEH, more research is needed to better understand the potential connection to achondroplasia. For management, we suggest shared surgical decision making based on symptoms.

Background: Depression is a chronic condition that affects up to 15% of older adults. The healthogenic effects of regular exercise are well established, but it is still unclear which exercise-related variables characterise the antidepressant effects of exercise. Thus, the purpose of this study was to examine the extent to which exercise-related variables (exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support) can predict depressive symptoms in a cohort of community-dwelling older adults. Methods: This study employed a cross-sectional analysis of questionnaire data from a sample of 586 community-dwelling older Australians aged 65 to 96 years old. Participants completed the Center for Epidemiologic Studies Depression Scale, modified CHAMPS Physical Activity Questionnaire for Older Adults, Four-Dimension Mood Scale, Self-Efficacy for Exercise Scale, and Social Provisions Scale – Short Form. Bivariate correlations were performed, and hierarchical multiple regression was subsequently used to test the regression model. Results: Exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support were all negatively associated with depressive symptoms (r = −0.20 to −0.56). When the variables were entered as predictors into the hierarchical multiple regression model, social support was the strongest predictor of depressive symptoms (β = −0.42), followed by exercise-induced mood (β = −0.23), and exercise self-efficacy (β = −0.07). Exercise behaviour did not explain any additional variance in depressive symptoms. A modest interaction effect was also observed between exercise-induced mood and social support. Conclusion: These findings indicate that social support is the strongest predictor of depressive symptomology in community-dwelling older adults, particularly when combined with positive exercise-induced mood states. When addressing the needs of older adults at risk of depression, healthcare professionals should consider the implementation of exercise programmes that are likely to benefit older adults by improving mood, enhancing self-efficacy, and building social support.

Structural shifts behind the rise of podcasting have led to programming aimed at sustaining audience attention, a development coinciding with the sharp increase in engaged time with digital longform content among mobile users. This study industrially and culturally situates 3 case studies: True Murder (a pioneering precursor to This American Life producers' Serial), S-Town (Serial's successor that far exceeded its listenership), and Ear Hustle (Radiotopia's experiment in subject-produced content made by two inmates at San Quentin State Prison). Each case illustrates how distinct sectors of the podcasting industry approach the production of absorbing nonfiction through transparent journalism featuring self-reflexive metanarrative.

We describe a lithographic approach--nanocrystal plasma polymerization-based lithography--in which colloidal nanocrystal assemblies (CNAs) are used as the inorganic resist and, potentially, the active material. The patterning process is based on a change in the dispersibility of the CNAs in solvents as a result of the exposure to plasmas. Plasmas can etch the capping ligands from the exposed area. During the development step, the unexposed area of CNAs is redispersed, leaving behind the patterned area, similar to what is expected from negative photoresist. [ABSTRACT FROM AUTHOR]

Hypertrophic scar (HSc) occurs in 40–70% of patients treated for third degree burn injuries. Current burn therapies rely upon the use of bioengineered skin equivalents (BSEs), which assist in wound healing but do not prevent HSc contraction. HSc contraction leads to formation of a fixed, inelastic skin deformity. We propose that BSEs should maintain their architecture in the wound bed throughout the remodeling phase of repair to prevent HSc contraction. In this work we study a degradable, elastomeric, randomly oriented, electrospun micro-fibrous scaffold fabricated from the copolymer poly( l -lactide-co-ε-caprolactone) (PLCL). PLCL scaffolds displayed appropriate elastomeric and tensile characteristics for implantation beneath a human skin graft. In vitro analysis using human dermal fibroblasts demonstrated that PLCL scaffolds decreased myofibroblast formation as compared to an in vitro HSc contraction model. Using a validated immune-competent murine HSc contraction model, we found that HSc contraction was significantly greater in animals treated with standard of care, Integra, as compared to those treated with collagen coated-PLCL (ccPLCL) scaffolds. Finally, wounds treated with ccPLCL were significantly less stiff than control wounds at d30 in vivo. Together, these data suggest that scaffolds which persist throughout the remodeling phase of repair may represent a clinically translatable method to prevent HSc contraction. [ABSTRACT FROM AUTHOR]

There are currently limited investigations that have examined the relationship between personality traits and exercise dependence. The purpose of the present study was to explore the relationship between exercise dependence, narcissism and perfectionism. Ninety regular exercisers were recruited from various gyms, fitness centres and sporting events to complete the Narcissistic Personality Inventory [Raskin, R. N., & Terry, H. (1988). A principal-components analysis of the Narcissistic Personality Inventory and further evidence of its construct validity.Journal of Personality and Social Psychology,54(5), 890–902], Multidimensional Perfectionism Scale [Hewitt, P. L., & Flett, G. L. (1991). Perfectionism in the self and social contexts: Conceptualization, assessment, and association with psychopathology.Journal of Personality and Social Psychology,60(3), 456–470] and Exercise Dependence Scale-Revised [Symons Down, D., Hausenblas, H. A., & Nigg, C. R. (2004). Factorial validity and psychometric examination of the Exercise Dependence Scale-Revised.Measurement in Physical Education and Exercise Science,8(4), 183–201] either online or in person. Exercise dependence was positively related to narcissism, self-orientated perfectionism and socially prescribed perfectionism. Gender differences between these relationships were also found. Hierarchical regression analysis indicated that a combination of narcissism and self-orientated perfectionism uniquely predicted a greater degree of exercise dependence. These findings indicate that both narcissism and perfectionism may be important antecedents of exercise dependence, and that a combination of these personality traits is associated with exercise dependence. Future research should continue to determine which personality traits contribute to the personality profile of individuals with exercise dependence. [ABSTRACT FROM PUBLISHER]

Hypertrophic scar ( HSc) contraction following burn injury causes contractures. Contractures are painful and disfiguring. Current therapies are marginally effective. To study pathogenesis and develop new therapies, a murine model is needed. We have created a validated immune-competent murine HSc model. A third-degree burn was created on dorsum of C57 BL/6 mice. Three days postburn, tissue was excised and grafted with ear skin. Graft contraction was analyzed and tissue harvested on different time points. Outcomes were compared with human condition to validate the model. To confirm graft survival, green fluorescent protein ( GFP) mice were used, and histologic analysis was performed to differentiate between ear and back skin. Role of panniculus carnosus in contraction was analyzed. Cellularity was assessed with 4′,6-diamidino-2-phenylindole. Collagen maturation was assessed with Picro-sirius red. Mast cells were stained with Toluidine blue. Macrophages were detected with F4/80 immune. Vascularity was assessed with CD31 immune. RNA for contractile proteins was detected by quantitative real-time polymerase chain reaction (q RT- PCR). Elastic moduli of skin and scar tissue were analyzed using a microstrain analyzer. Grafts contracted to ∼45% of their original size by day 14 and maintained their size. Grafting of GFP mouse skin onto wild-type mice, and analysis of dermal thickness and hair follicle density, confirmed graft survival. Interestingly, hair follicles disappeared after grafting and regenerated in ear skin configuration by day 30. Radiological analysis revealed that panniculus carnosus doesn't contribute to contraction. Microscopic analyses showed that grafts show increase in cellularity. Granulation tissue formed after day 3. Collagen analysis revealed increases in collagen maturation over time. CD31 stain revealed increased vascularity. Macrophages and mast cells were increased. q RT- PCR showed up-regulation of transforming growth factor beta, alpha smooth muscle actin, and rho-associated protein kinase 2 in HSc. Tensile testing revealed that human skin and scar tissues are tougher than mouse skin and scar tissues. [ABSTRACT FROM AUTHOR]

Adult-onset spontaneous osteonecrosis of the tarsal navicular joint, or Mueller-Weiss syndrome (MWS), is an uncommon debilitating disease characterized by a painful clinical course with progressive midfoot deformity. Treatment options include nonoperative management and/or operative intervention, including percutaneous decompression of the navicular bone, stabilization of existing structures, and cancellous bone grafting from the tibia or iliac crest. To our knowledge, there have been no reported cases of treatment of MWS with a vascularized bone graft. We report an unusual case of unilateral MWS in a 25-year-old male who failed nonoperative therapy and was successfully treated with a novel operative approach using debridement followed by a free medial femoral condyle vascularized bone graft. At 18-month follow-up, the patient demonstrated an excellent outcome with return to previous level of function, including work-related and recreational activities.Level Of Evidence: Therapeutic, Level IV: Case study.

A variety of terminal chain modifications ( Y ) were made on the diacetylenes in which X =C n H 2 n +1 , C 12 H 25 O and F, and Y =CH 2 CH(Me)C 2 H 5 , COCH 3 , C≡CC 5 H 11 , C n F 2 n +1 C n H 2 n +1 and CH=CHCO 2 C 3 H 7 . Mesomorphic properties were determined by hot stage polarizing microscopy and DSC. These were compared with those for the dialkyl analogues ( X =C m H 2 m +1 , Y =C n H 2 n +1 ) and a series of 1- and 2-olefins ( Y =CH=CHC n H 2 n +1 and CH 2 CH=CHC n H 2 n +1 ). The 1-olefin series showed wider range nematics than the dialkyl compounds, whereas the above modifications showed either narrow range nematic phases, no mesophase or higher melting temperatures. New transition temperature and enthalpy data are provided for some of the dialkyl and F-alkyl compounds previously reported, for comparisons. Preliminary birefringence data are also included along with the results of some heat and UV stability studies. [ABSTRACT FROM AUTHOR]

A limited selection of ring modified diphenyldiacetylenes of the type where A = , Y =C n H 2 n +1 , CF 3 , F, COMe, NH 2 , and NMe 2 , and A = , trans and cis with Y =F and trans with Y =C 3 H 7 , were synthesized. Mesomorphic properties were determined by hot stage polarizing microscopy and DSC. These properties were generally poorer than those found in the parent benzene compounds. This was also true of some pyrimidine analogues reported earlier. Birefringence values also decreased as expected. [ABSTRACT FROM AUTHOR]

• Older adults can benefit from either aerobic, resistance, or mind-body exercise. • Exercise is a therapeutic ally to pharmacological treatment of clinical depression. • Pooled NMA evidence demonstrates high compliance and tolerance of exercise. • There is opportunity for patients to select their preferred type(s) of exercise. • Clinicians should facilitate exercise prescription based on patient preference. Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults. We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception – September 12th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire. A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = −0.87 to −1.38), followed by aerobic exercise (g = −0.51 to −1.02), and resistance exercise (g = −0.41 to −0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = −0.10, PrI = −2.23, 2.03), mind-body versus aerobic (g = −0.36, PrI = −2.69, 1.97), or mind-body versus resistance (g = −0.46, PrI = −2.75, 1.83). These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression.
