    The growing obesity pandemic has caused diabetes to become one of the world’s leading health concerns. Diabetic individuals often suffer from peripheral neuropathy, which is nerve death that typically starts at the extremities and moves from the skin inward to deeper tissues. This nerve death causes painful symptoms including tingling, stinging, numbness, and others. Current methods to diagnose peripheral neuropathy by measuring nerve function are invasive and painful since they target large axons of the legs; however, by the time the neuropathy reaches the diagnosable axons, it is often too late for intervention. Although no cures for neuropathy are established, aside from analgesics for pain, there are options for mitigating worsening of the disease if diagnosed early enough (for example, glucose control for diabetic neuropathy). There is a critical need for early detection and diagnosis of peripheral neuropathy as obesity and diabetes continue to plague the world. Microneedle fabrication is a growing research area, especially in transdermal drug delivery due to their minimal invasive, pain-free application. The objective of this project is to design a platform using electrically conductive microneedles for early detection of peripheral neuropathy. Using these needles, neurophysiology can be employed to record electrical signal just below the skin to determine the integrity of the nerves to track neuropathy progression. Thus far, prototypes of the device have been tested on mice to establish protocols and understand the hardware and software, with the goal of eventually developing a usable prototype for a longitudinal study of diseased mice and human clinical studies

    An exploration of the impact of attachment, parental meta-emotion, and emotion regulation in adoptive families

    Due to being at risk for a number of unfavorable environmental factors (Barcons, Abrines, Brun, Sartini, Fumadó, & Marre, 2014), adopted children have an increased likelihood of developing social, emotional, cognitive, and attachment issues (Rushton, 2010). Whether adopted domestically or internationally, adopted children are at risk for experiencing socio-emotional difficulties (Dalen & Theie, 2014; Vandivere, Malm, & Radel, 2009; Vandivere & McKlindon, 2010) that can stunt the child’s ability to effectively regulate their emotions and connect with others. Adoptive parents may find it difficult to emotionally connect with adopted children who are experiencing socio-emotional difficulties (Dalen & Theie, 2014). Adoptive parents can aid their adopted children in learning how to connect emotionally and regulate difficult emotions through emotion coaching (Gottman, Katz, & Hooven, 1996). Emotion coaching is a construct based in a parent’s meta-emotion philosophy (PMEP), which is defined as parents’ thoughts and feelings about their own emotions as well as their child’s emotions. Emotion coaching is one of the four PMEPs and is considered the ideal PMEP. Emotion coaching parents accept and validate all of their children’s emotions, and views their children’s emotional expression as an opportunity to connect with them and teach them how to manage challenging emotions. Researchers (e.g., Ellis, Alisic, Reiss, Dishion, & Fisher, 2013) has shown that children of emotion coaching parents have higher levels of emotion regulation than children of parents with less ideal PMEPs. But how do parents develop their thoughts and feelings about their own emotions and their children’s emotions? Attachment Theory (Bowlby, 1969) may lend some answers to this question. Attachment Theory emphasizes the importance of emotional attunement between the mother and infant when developing secure attachment: the ability to form intimate relationships with others (Bowlby, 1969; Gus, Rose, & Gilbert, 2015). According to Attachment Theory, an individual cannot respond to others with empathic attunement unless they have secure attachment (Bowlby, 1969). The very act of emotion coaching seems to require high levels of emotional attunement between mother and child. Bowlby (1969) emphasized the importance of the mother as a primary attachment figure, and so this study will be looking at the adoptive mother’s attachment and PMEP. Although researchers (e.g., Cowen, 1996; Chen, Lin, & Li, 2012) have made connections between Attachment Theory and PMEP in biological families, they have not yet explored these constructs in adoptive families. Thus, the purpose of this study was to gain a better understanding of how adult attachment may or may not influence adoptive mothers’ PMEP and how adoptive adult attachment and PMEP may or may not influence adopted children’s ability to emotionally regulate and attach to their adoptive parent. Because the ideal PMEP is emotion coaching, the researcher measured this type of PMEP only. Adoptive mothers completed questionnaires assessing their attachment, level of emotion coaching, and their view of their child’s ability to emotionally regulate. Utilizing Pearson’s pairwise correlations, the researcher analyzed the relationships between the adoptive mothers’ level of emotion coaching and her attachment; the relationship between the adoptive mothers’ level of emotion coaching and her child’s emotion regulation skills; and the relationship between the adopted mothers’ attachment and her child’s emotion regulation skills. The researcher discovered that there was a statistically significant negative relationship between emotion coaching and adult attachment; a statistically significant positive relationship between emotion coaching and emotion regulation; and statistically significant positive relationship between attachment and lability. Finally, the researcher utilized a regression analysis to discover that the adoptive mothers’ level of emotion coaching acted as a mediator between the adoptive mothers’ attachment and the adopted child’s level of emotion regulation. These findings indicated that emotion coaching is an effective method of aiding adopted children’s ability to emotionally regulate. Furthermore, the findings indicated that even if an adoptive mother is struggling with attachment, if she is able to learn emotion coaching, she may still have a positive effect on her adopted child’s emotion regulation development

    Evaluation of Nintendo Wii Balance Board as a Tool for Measuring Postural Stability After Sport-Related Concussion

    Get PDF
    Recent changes to postconcussion guidelines indicate that postural-stability assessment may augment traditional neurocognitive testing when making return-to-participation decisions. The Balance Error Scoring System (BESS) has been proposed as 1 measure of balance assessment. A new, freely available software program to accompany the Nintendo Wii Balance Board (WBB) system has recently been developed but has not been tested in concussed patients

    Abstract Serum samples from all twenty-three known living members of the Crocodylia were tested for antibacterial activity against eight bacterial species. These data were used to generate an immune profile for each crocodylian species. Statistical analyses revealed that the three living lineages of crocodylians, Alligatoroidea, Crocodyloidea, and Gavialoidea, were distinguishable by their immunological activities. For instance, species within the Alligatoroidea and Crocodyloidea exhibited remarkable immune activity similarities to others in their own lineages. Comparisons of the members of the different lineages, however, revealed substantial differences in immune profiles. Furthermore, species that are in the same genus were shown to exhibit more immune similarities to each other than to members of other genera within the same family. Finally, our immunological analyses reveal that Tomistoma schlegelii aligns more closely with the Gavialoidea than the Crocodyloidea.

    Transcriptome sequencing identifies SPL7-regulated copper acquisition genes FRO4/FRO5 and the copper dependence of iron homeostasis in Arabidopsis

    24 Pags., 9 Figs., 2 Tabls., with Supplemental Data (15 Figs., 3 Tabls., 1 Method, 1 Data Set).The transition metal copper (Cu) is essential for all living organisms but is toxic when present in excess. To identify Cu deficiency responses comprehensively, we conducted genome-wide sequencing-based transcript profiling of Arabidopsis thaliana wild-type plants and of a mutant defective in the gene encoding SQUAMOSA PROMOTER BINDING PROTEIN-LIKE7 (SPL7), which acts as a transcriptional regulator of Cu deficiency responses. In response to Cu deficiency, FERRIC REDUCTASE OXIDASE5 (FRO5) and FRO4 transcript levels increased strongly, in an SPL7-dependent manner. Biochemical assays and confocal imaging of a Cu-specific fluorophore showed that high-affinity root Cu uptake requires prior FRO5/FRO4-dependent Cu(II)-specific reduction to Cu(I) and SPL7 function. Plant iron (Fe) deficiency markers were activated in Cu-deficient media, in which reduced growth of the spl7 mutant was partially rescued by Fe supplementation. Cultivation in Cu-deficient media caused a defect in root-to-shoot Fe translocation, which was exacerbated in spl7 and associated with a lack of ferroxidase activity. This is consistent with a possible role for a multicopper oxidase in Arabidopsis Fe homeostasis, as previously described in yeast, humans, and green algae. These insights into root Cu uptake and the interaction between Cu and Fe homeostasis will advance plant nutrition, crop breeding, and biogeochemical research.We acknowledge postdoctoral fellowships to M.B. from the Alexander von Humboldt Foundation and the Spanish Ministry of Science and Innovation; a Deutsche Forschungsgemeinshaft Heisenberg fellowship and funding from the FRONTIERS program at the University of Heidelberg, Germany, and the European Union InP Public Health Impact of Long-Term, Low-Level Mixed Element Exposure in Susceptible Population Strata (FOOD-CT-2006-016253) to U.K.; a grant from the National Science Foundation (IOS-0919739) to E.L.C.; a postdoctoral fellowship from the Spanish Foundation of Science and Technology (MEC-FECYT) to D.C.; National Institutes of Health Grant GM42143 to S.S.M.; and support from the University of California, Los Angeles–Department of Energy Institute for Genomics and Proteomics under Contract DE-FC02-02ER63421 to M.P.Peer reviewe

    Comparison of patient comprehension of rapid HIV pre-test fundamentals by information delivery format in an emergency department setting

    <p>Abstract</p> <p>Background</p> <p>Two trials were conducted to compare emergency department patient comprehension of rapid HIV pre-test information using different methods to deliver this information.</p> <p>Methods</p> <p>Patients were enrolled for these two trials at a US emergency department between February 2005 and January 2006. In Trial One, patients were randomized to a no pre-test information or an in-person discussion arm. In Trial Two, a separate group of patients were randomized to an in-person discussion arm or a Tablet PC-based video arm. The video, "Do you know about rapid HIV testing?", and the in-person discussion contained identical Centers for Disease Control and Prevention-suggested pre-test information components as well as information on rapid HIV testing with OraQuick<sup>®</sup>. Participants were compared by information arm on their comprehension of the pre-test information by their score on a 26-item questionnaire using the Wilcoxon rank-sum test.</p> <p>Results</p> <p>In Trial One, 38 patients completed the no-information arm and 31 completed the in-person discussion arm. Of these 69 patients, 63.8% had twelve years or fewer of formal education and 66.7% had previously been tested for HIV. The mean score on the questionnaire for the in-person discussion arm was higher than for the no information arm (18.7 vs. 13.3, p ≤ 0.0001). In Trial Two, 59 patients completed the in-person discussion and 55 completed the video arms. Of these 114 patients, 50.9% had twelve years or fewer of formal education and 68.4% had previously been tested for HIV. The mean score on the questionnaire for the video arm was similar to the in-person discussion arm (20.0 vs. 19.2; p ≤ 0.33).</p> <p>Conclusion</p> <p>The video "Do you know about rapid HIV testing?" appears to be an acceptable substitute for an in-person pre-test discussion on rapid HIV testing with OraQuick<sup>®</sup>. In terms of adequately informing ED patients about rapid HIV testing, either form of pre-test information is preferable than for patients to receive no pre-test information.</p

    A family cognitive-behavioral preventive intervention for parents with a history of depression and their 9–15-year-old children was compared with a self-study written information condition in a randomized clinical trial (n = 111 families). Outcomes were assessed at postintervention (2 months), after completion of 4 monthly booster sessions (6 months), and at 12-month follow-up. Children were assessed by child reports on depressive symptoms, internalizing problems, and externalizing problems; by parent reports on internalizing and externalizing problems; and by child and parent reports on a standardized diagnostic interview. Parent depressive symptoms and parent episodes of major depression also were assessed. Evidence emerged for significant differences favoring the family group intervention on both child and parent outcomes; strongest effects for child outcomes were found at the 12-month assessment with medium effect sizes on most measures. Implications for the prevention of adverse outcomes in children of depressed parents are highlighted

    Correlates of women's cancer screening and contraceptive knowledge among female emergency department patients

    <p>Abstract</p> <p>Background</p> <p>Lack of knowledge regarding preventive health services for women might impede campaigns to expand these services in the emergency department setting. For 18–55-year-old English-speaking women visiting an urban emergency department, we aimed to: (1) Ascertain their knowledge regarding the applicability, purpose, and recommended intervals of three women's cancer screening and three contraceptive methods; and (2) Determine if patient age, race/ethnicity, medical insurance status, and current or recent usage of these methods are associated with greater or lesser knowledge about them.</p> <p>Methods</p> <p>Emergency department-based survey on recent or current usage and knowledge about Pap smears, breast self-examinations, mammograms, condoms, birth control, and emergency contraception. Analyses included calculation of summary statistics and creation of multivariable logistic regression models.</p> <p>Results</p> <p>Of 1,100 patients eligible for the study, 69.9% agreed to participate. Most of the participants were < age 35, white, single (never married and no partner), Catholic, and had private medical insurance. Participant's recent or current usage of a particular cancer screening or contraceptive method varied by type of method: Pap smear within the past year (69.1%), breast self-exam within the past month (45.5%), mammogram within the past year (65.7% for women age 45–55), condom usage during every episode of sexual intercourse (15.4%), current usage of birth control pills (17.8%), and ever use of emergency contraception (9.3%). The participants correctly answered 87.9% of all survey questions about condoms, 82.5% about birth control pills, 78.5% about breast self-exams, 52.9% about Pap smears, 35.4% about mammograms, and 25.0% about emergency contraception. In multivariable logistic regression models, survey participants who had private medical insurance and those who recently or currently used a given screening or contraceptive method had a greater odds of correctly answering all questions about each cancer screening or contraceptive method.</p> <p>Conclusion</p> <p>Although these female ED patients demonstrated strong knowledge on some women's cancer screening and contraceptive methods, there were several areas of knowledge deficit. Women without private medical insurance and those who have not used a particular cancer screening or contraceptive method demonstrated less knowledge. Reduced knowledge about women's cancer screening and contraceptive methods should be considered during clinical encounters and when instituting or evaluating emergency department-based initiatives that assess the need for these methods.</p

    The ENIGMA sports injury working group - an international collaboration to further our understanding of sport-related brain injury

    Get PDF
    Sport-related brain injury is very common, and the potential long-term effects include a wide range of neurological and psychiatric symptoms, and potentially neurodegeneration. Around the globe, researchers are conducting neuroimaging studies on primarily homogenous samples of athletes. However, neuroimaging studies are expensive and time consuming, and thus current findings from studies of sport-related brain injury are often limited by small sample sizes. Further, current studies apply a variety of neuroimaging techniques and analysis tools which limit comparability among studies. The ENIGMA Sports Injury working group aims to provide a platform for data sharing and collaborative data analysis thereby leveraging existing data and expertise. By harmonizing data from a large number of studies from around the globe, we will work towards reproducibility of previously published findings and towards addressing important research questions with regard to diagnosis, prognosis, and efficacy of treatment for sport-related brain injury. Moreover, the ENIGMA Sports Injury working group is committed to providing recommendations for future prospective data acquisition to enhance data quality and scientific rigor

    Objectively measured patterns of sedentary time and physical activity in young adults of the Raine study cohort

    Get PDF
    Background: To provide a detailed description of young adults' sedentary time and physical activity. Methods: 384 young women and 389 young men aged 22.1±0.6 years, all participants in the 22 year old follow-up of the Raine Study pregnancy cohort, wore Actigraph GT3X+ monitors on the hip for 24 h/day over a one-week period for at least one 'valid' day (=10 h of waking wear time). Each minute epoch was classified as sedentary, light, moderate or vigorous intensity using 100 count and Freedson cut-points. Mixed models assessed hourly and daily variation; t-tests assessed gender differences. Results: The average (mean±SD) waking wear time was 15.0±1.6 h/day, of which 61.4±10.1 % was spent sedentary, 34.6±9.1 % in light-, 3.7±5.3 % in moderate- and, 0.3±0.6 % in vigorous-intensity activity. Average time spent in moderate to vigorous activity (MVPA) was 36.2±27.5 min/day. Relative to men, women had higher sedentary time, but also higher vigorous activity time. The 'usual' bout duration of sedentary time was 11.8±4.5 min in women and 11.7±5.2 min in men. By contrast, other activities were accumulated in shorter bout durations. There was large variation by hour of the day and by day of the week in both sedentary time and MVPA. Evenings and Sundays through Wednesdays tended to be particularly sedentary and/or inactive. Conclusion: For these young adults, much of the waking day was spent sedentary and many participants were physically inactive (low levels of MVPA). We provide novel evidence on the time for which activities were performed and on the time periods when young adults were more sedentary and/or less active. With high sedentary time and low MVPA, young adults may be at risk for the life-course sequelae of these behaviours
