Parental strategies used in the family meal session of Family-Based Treatment adolescent anorexia nervosa : links with treatment outcomes

Examine relationships between parental mealtime strategies used in the family meal session of Family-Based Treatment (FBT) and adolescent outcomes at EOT (session 20). Method: Eighteen families with an adolescent receiving FBT-AN participated. Parental strategies during videoed family meals were assessed using a family mealtime coding system. Change scores were calculated for both adolescent %EBW and EDE scores. Results: Increased use of parental direct and non-direct eating prompts during the family meal was associated with greater adolescent weight gain at EOT. Use of parental mealtime strategies was not associated with any significant change in adolescent eating psychopathology at EOT. Discussion: Parental verbal eating prompts during the family meal may be effective in promoting short-term weight gain. During the family meal session, parents should be encouraged to maintain a direct focus on their adolescent child’s eating behaviour which may assist their child with food consumption and potential weight gain. Further research examining food-based interactions among parents and their adolescent child with AN is needed

How do parents of adolescent patients with anorexia nervosa interact with their child at mealtimes? A study of parental strategies used in the family meal session of family-based treatment

Objective: To examine the range and frequency of parental mealtime strategies used during the family meal session of Family-Based Treatment (FBT) for adolescent anorexia nervosa, and to explore the relationships between parental mealtime strategies, mealtime emotional tone and parental 'success' at encouraging adolescent food consumption. Method: Participants were 21 families with a child aged between 12 and 18 years receiving FBT for adolescent anorexia nervosa. Video recordings of the family meal session (FBT session two) were coded using the Family Mealtime Coding System adapted in this study for use with adolescents (FMCS-A) to identify frequency of parental strategies, emotional tone of the meal (measured by adolescent positive and negative vocalisations) and frequency of prompted mouthfuls consumed by the adolescent (measured by the number of mouthfuls consumed by the adolescent immediately following parental interactions). Results: A range of parental mealtime strategies were in use. Those used repeatedly included direct eating prompts, non-direct eating prompts, physical prompts, and providing information or food-related choices. Several parental mealtime strategies (direct and non-direct eating prompts) were found to be consistently associated with the tone of adolescents' vocalisations and the number of mouthfuls consumed in response to a parental prompt. Discussion: Despite associations with negativity from the adolescent, the use of food-related prompts (both verbal and physical) seems to be associated with increased eating. This indicates the potentially important role of parental control of eating. Following replication, these findings might provide a focus for therapists when supporting and coaching parents during the family meal session. © 2014 Wiley Periodicals, Inc

Development of the Mealtime Emotions Measure for adolescents (MEM-A): Gender differences in emotional responses to family mealtimes and eating psychopathology

This study aimed to examine the factor structure of the Mealtime Emotions Measure for adolescents (MEM-A), a novel measure of emotional responses experienced during family mealtimes. Additionally, it examined gender differences in mealtime emotions and also the relationships between mealtime emotions and levels of eating psychopathology, when controlling for anxiety or depression. Adolescent participants (N = 527; 282 girls, 245 boys) with a mean age of 15.9 years completed the new mealtime measure for adolescents (MEM-A), in addition to questions about family mealtime atmosphere, and measures assessing symptoms of anxiety, depression, and eating psychopathology. Factor analysis produced a three factor solution for the MEM-A with two subscales relating to different types of negative mealtime emotions (Anxiety-related mealtime emotions and Anger-related mealtime emotions) and one subscale relating to Positive mealtime emotions. Generally, girls reported experiencing more Anxiety-related mealtime emotions compared to boys. Having conducted separate analyses controlling for levels of either anxiety or depression, there were several significant associations for both girls and boys between mealtime emotions, particularly Anxiety-related emotions, and eating psychopathology. The findings suggest that some mealtime emotions are associated with increased eating psychopathology. Replication and detailed examination of these emotional responses is required.

Opposing roles of primate areas 25 and 32 and their putative rodent homologs in the regulation of negative emotion

Disorders of dysregulated negative emotion such as depression and anxiety also feature increased cardiovascular mortality and decreased heart-rate variability (HRV). These disorders are correlated with dysfunction within areas 25 and 32 of the ventromedial prefrontal cortex (vmPFC), but a causal relationship between dysregulation of these areas and such symptoms has not been demonstrated. Furthermore, cross-species translation is limited by inconsistent findings between rodent fear extinction and human neuroimaging studies of negative emotion. To reconcile these literatures, we applied an investigative approach to the brain–body interactions at the core of negative emotional dysregulation. We show that, in marmoset monkeys (a nonhuman primate that has far greater vmPFC homology to humans than rodents), areas 25 and 32 have causal yet opposing roles in regulating the cardiovascular and behavioral correlates of negative emotion. In novel Pavlovian fear conditioning and extinction paradigms, pharmacological inactivation of area 25 decreased the autonomic and behavioral correlates of negative emotion expectation, whereas inactivation of area 32 increased them via generalization. Area 25 inactivation also increased resting HRV. These findings are inconsistent with current theories of rodent/primate prefrontal functional similarity, and provide insight into the role of these brain regions in affective disorders. They demonstrate that area 32 hypoactivity causes behavioral generalization relevant to anxiety, and that area 25 is a causal node governing the emotional and cardiovascular symptomatology relevant to anxiety and depression.This research was funded by Medical Research Council Career Development Award RG62920 (to H.F.C.).

Active Terahertz Modulator and Slow Light Metamaterial Devices with Hybrid Graphene-Superconductor Photonic Integrated Circuits.

Metamaterial photonic integrated circuits with arrays of hybrid graphene-superconductor coupled split-ring resonators (SRR) capable of modulating and slowing down terahertz (THz) light are introduced and proposed. The hybrid device's optical responses, such as electromagnetic-induced transparency (EIT) and group delay, can be modulated in several ways. First, it is modulated electrically by changing the conductivity and carrier concentrations in graphene. Alternatively, the optical response can be modified by acting on the device temperature sensitivity by switching Nb from a lossy normal phase to a low-loss quantum mechanical phase below the transition temperature (Tc) of Nb. Maximum modulation depths of 57.3% and 97.61% are achieved for EIT and group delay at the THz transmission window, respectively. A comparison is carried out between the Nb-graphene-Nb coupled SRR-based devices with those of Au-graphene-Au SRRs, and significant enhancements of the THz transmission, group delay, and EIT responses are observed when Nb is in the quantum mechanical phase. Such hybrid devices with their reasonably large and tunable slow light bandwidth pave the way for the realization of active optoelectronic modulators, filters, phase shifters, and slow light devices for applications in chip-scale future communication and computation systems

The Office

This newsletter was created by the Fall 2016 Honors English Class from Stephen F. Austin State University. Throughout the semester students were asked to define and interpret the terms work and labor. Through our individual research on different aspects of work and labor, we hope to expand the general spectrum of what encompasses these topics. Works and labor are two important aspects of our culture. They are umbrella terms that encompass many occupational fields and serve as a uniting factor in modern-day society. Aspects of work and labor are observable in an assortment of environments, whether it be through schoolwork as children or salary-paying jobs as adults. Because the global employment industry as a whole has such strong relations to work and labor ingrained in how duties are completed, there is a wide range of areas where they are applicable. Here, in this newsletter, many different aspects of these terms will be discussed. There are more elements to work and labor than many realize. Through the works included in our newsletter, we hope to expand the general understanding of work, labor, and the components that make them what they are

Clinical and Molecular Features of Renal and Pheochromocytoma/Paraganglioma Tumor Association Syndrome (RAPTAS): Case Series and Literature Review.

CONTEXT: The co-occurrence of pheochromocytoma (PC) and renal tumors was linked to the inherited familial cancer syndrome von Hippel-Lindau (VHL) disease more than six decades ago. Subsequently, other shared genetic causes of predisposition to renal tumors and to PC, paraganglioma (PGL), or head and neck paraganglioma (HNPGL) have been described, but case series of non-VHL-related cases of renal tumor and pheochromocytoma/paraganglioma tumor association syndrome (RAPTAS) are rare. OBJECTIVE: To determine the clinical and molecular features of non-VHL RAPTAS by literature review and characterization of a case series. DESIGN: A review of the literature was performed and a retrospective study of referrals for investigation of genetic causes of RAPTAS. RESULTS: Literature review revealed evidence of an association, in addition to VHL disease, between germline mutations in SDHB, SDHC, SDHD, TMEM127, and MAX genes and RAPTAS [defined here as the co-occurrence of tumors from both classes (PC/PGL/HNPGL and renal tumors) in the same individual or in first-degree relatives]. In both the literature review and our case series of 22 probands with non-VHL RAPTAS, SDHB mutations were the most frequent cause of non-VHL RAPTAS. A genetic cause was identified in 36.3% (8/22) of kindreds. CONCLUSION: Renal tumors and PC/PGL/HNPGL tumors share common molecular features and their co-occurrence in an individual or family should prompt genetic investigations. We report a case of MAX-associated renal cell carcinoma and confirm the role of TMEM127 mutations with renal cell carcinoma predisposition
