DEVELOPING A MEASURE OF AMBIVALENCE ABOUT DRINKING LESS ALCOHOL: PSYCHOMETRIC PROPERTIES AND CONSTRUCT VALIDITY

The resolution of ambivalence is an appealing explanation of how at-risk drinkers make changes in their alcohol consumption; however, limited research about this potential mechanism of change exists due to the lack of a specific measure of ambivalence about drinking less alcohol. An initial item pool measuring ambivalence was assessed in two different samples of at-risk drinkers, undergraduate college students participating in the study for research participation credit (N1 = 129) and participants recruited from online sources (N2 = 128) using an online web survey. Three different methods of measuring ambivalence were tested: a double-barreled items method, a difference score method calculated from the sum of items measuring both motivation to change as well as motivation to maintain the status quo, and an Emotion items method. Exploratory Factor Analyses (EFAs) revealed a single factor structure for all three scales, and internally-consistent scales were formed from a subset of well-performing items based on item-scale and factor analytic results. Convergent and discriminant validity correlations were also examined. This study introduces the Change, Ambivalence, Sustain, and Emotion Scales (CASES) for eventual use in investigating if the resolution of ambivalence is a mechanism of change in at-risk drinkers. Limitations and directions for future research are also discussed

Lower Extremity Salvage in the Setting of Bullous Pemphigoid Exacerbation: A Case Report

Bullous pemphigoid is an autoimmune blistering disease where patients suffer from painful bullae, often covering large portions of the skin and requiring management with immune-suppression. Our case report of recurring bullous pemphigoid illustrates the importance of considering immunosuppressive perioperative management in patients with a history of autoimmune blistering even when the disease has been quiescent for some time. With multidisciplinary care and immune suppressive therapies in the perioperative period, a free flap complicated by recurrent bullous pemphigoid can be salvaged

Life after lockdown: Zooming out on perceptions in the post-videoconferencing era

Background: The COVID-19 pandemic has deeply disrupted daily life across the globe, with profound effects on mental and physical health. After more than a year of isolation and communication via videoconferencing, people are returning to in-person activities. Objective: This study aimed to investigate worsening self-perception, mental health, and anxiety with the return to in-person activities, with a focus on the influence of videoconferencing, social media, and the use of filters. Methods: An anonymous survey was distributed online through social media platforms and student network pages. Results: A total of 7295 participants responded to the survey. Seventy-one precent reported anxiety or stress related to returning to in-person activities, and nearly 64% sought mental health support services. Thirty-percent stated they plan to invest in their appearance as a coping strategy to deal with the anxiety of returning to in-person, and \u3e 30% plan to take action in changing their appearance. The most reported dermatologic concerns were skin discoloration (32.36%), wrinkles (24.45%), and acne (14.85%). The prevalence of anxiety and mental health services increased relative to the use of filters in 18- to 24 year-olds. Conclusion: This survey study of \u3e 7000 participants across the country elucidates worsening self-perception, anxiety, and mental health as we return to in-person activities in relation to increased videoconferencing, social media usage, and the use of filters. Physicians should be aware of these effects to better serve their patients

Dying neurons in thalamus of asphyxiated term newborns and rats are autophagic.

OBJECTIVE: Neonatal hypoxic-ischemic encephalopathy (HIE) still carries a high burden by its mortality and long-term neurological morbidity in survivors. Apart from hypothermia, there is no acknowledged therapy for HIE, reflecting the lack of mechanistic understanding of its pathophysiology. (Macro)autophagy, a physiological intracellular process of lysosomal degradation, has been proposed to be excessively activated in excitotoxic conditions such as HIE. The present study examines whether neuronal autophagy in the thalamus of asphyxiated human newborns or P7 rats is enhanced and related to neuronal death processes. METHODS: Neuronal autophagy and cell death were evaluated in the thalamus (frequently injured in severe HIE) of both human newborns who died after severe HIE (n = 5) and P7 hypoxic-ischemic rats (Rice-Vannuci model). Autophagic (LC3, p62), lysosomal (LAMP1, cathepsins), and cell death (TUNEL, caspase-3) markers were studied by immunohistochemistry in human and rat brain sections, and by additional methods in rats (immunoblotting, histochemistry, and electron microscopy). RESULTS: Following severe perinatal asphyxia in both humans and rats, thalamic neurons displayed up to 10-fold (p < 0.001) higher numbers of autophagosomes and lysosomes, implying an enhanced autophagic flux. The highly autophagic neurons presented strong features of apoptosis. These findings were confirmed and elucidated in more detail in rats. INTERPRETATION: These results show for the first time that autophagy is enhanced in severe HIE in dying thalamic neurons of human newborns, as in rats. Experimental neuroprotective strategies targeting autophagy could thus be a promising lead to follow for the development of future therapeutic approaches. Ann Neurol 2014;76:695-711

The learning style preferences of chiropractic students : a cross-sectional study

Objective: The aims of our study were to measure the learning style preferences of chiropractic students and to assess whether they differ across the 5 years of chiropractic study. Methods: A total of 407 (41.4% females) full-degree, undergraduate, and postgraduate students enrolled in an Australian chiropractic program agreed to participate in a cross-sectional survey comprised of basic demographic information and the Visual, Aural, Read/Write, Kinesthetic (VARK) questionnaire, which identifies learning preferences on four different subscales: visual, aural, reading/writing, and kinesthetic. Multivariate analysis of variance and the X² test were used to check for differences in continuous (VARK scores) and categorical (VARK category preference) outcome variables. Results: The majority of chiropractic students (56.0%) were found to be multimodal learners. Compared to the other learning styles preferences, kinesthetic learning was preferred by a significantly greater proportion of students (65.4%, p < .001) and received a significantly greater mean VARK score (5.66 ± 2.47, p < .001). Conclusions: To the best of our knowledge, this is the first time chiropractic students have been shown to be largely multimodal learners with a preference for kinesthetic learning. While this knowledge may be beneficial in the structuring of future curricula, more thorough research must be conducted to show any beneficial relationship between learning style preferences and teaching methods7 page(s
