Returning to work following cancer: a qualitative exploratory study into the experience of returning to work following cancer
The experience of returning to work following cancer is a largely unknown area of cancer research. This preliminary study aimed to explore the factors that influence decisions about return to work eitehr during or after cancer treatment and to identify the important aspects of returning to work. Qalitative data were collected using individual interview (n=19) and two focus groups (n=4, n=6), predominantly with breast cancer survivors. Patterns of returning to work were diverse and a variety of reasons influenced work decisions, including financial concerns and regaining normality. Participants also discussed their ability to work, health professionals' advice, side effects, support and adjustments, and attitudes towards work. Although the majority adapted well, a few encountered difficulties on their return. It is evident that more advice is requried from health professionals about returning to work, along with reasonable support and adjustments from employers to ensure that cancer survivors are able to successfully reintegrate back into the workforce
Design Matters in Community Gardens
With increased focus on local foods, food safety, nutrition, and physical health, community gardens are being created by a variety of entities, many of which are seeking assistance from Extension agents and specialists in the fields of horticulture, family consumer science, and 4-H. Extension professionals have expertise in nutrition, health, food safety, and food production, yet have little training in community garden design, which can provide the framework for successful gardens. Based on analysis of landscape elements of 10 professionally designed community gardens, recommendations were developed to help Extension professionals work with garden designers and volunteers
Chess Training Improves Cognition in Children
Systematic training of chess has beenshown to significantly increase the IQ and cognitivefunctioning among children. The study assessed theimpact of chess intervention on the IQ scores ofchildren and analyzed the cognitive functions thatcontributed to the IQ gain. Eighty-six schoolchildren, boys and girls in the age group (4-15)undergoing chess training were assessed using Binet-Kamat Test of Intelligence. Chess interventionconsisted of standardized bi-weekly training sessions of 2hoursā duration over a period of one year.Individual attention was given to every child byassigning one coach for every 4 students. Paired ttests and regression analysis were carried out.Significant increases were observed inIQ.Regression analysis indicated that non-verbalreasoning, language and memory significantlycontributed to the dependent variable IQ. The study hasimportant implications for education
O gene do receptor GABA A- Ī³2 (GABRG2) no transtorno obsessivo-compulsivo
OBJECTIVE: The Ī³-aminobutyric acid type A (GABA A) system may be implicated in obsessive-compulsive disorder, based on its major role in modulation of anxiety and its function as the principal inhibitory neurotransmitter system in the cortex. In addition, glutamatergic/GABAergic mechanisms appear to play a role in the pathophysiology of obsessive-compulsive disorder, making the GABA A receptor-Ī³2 (GABĻĪ³2) gene a good candidate for susceptibility in this disorder. METHOD: 118 probands meeting DSM-IV criteria for primary obsessive-compulsive disorder and their available parents were recruited for participation in this study and informed consent was obtained. An NciI restriction site polymorphism in the second intron was genotyped and data was analyzed using the Transmission Disequilibrium Test. RESULTS: In total, 61 of the participating families were informative (i.e., with at least one heterozygous parent). No biases were observed in the transmission of either of the two alleles (Ļ2 = 0.016, 1 d.f., p = 0.898) to the affected probands in the total sample. CONCLUSION/DISCUSSION: While these results do not provide support for a major role for the GABA A receptor-Ī³2 in obsessive-compulsive disorder, further investigations of this gene in larger samples are warranted
Non-photopic and photopic visual cycles differentially regulate immediate, early and late-phases of cone photoreceptor-mediated vision
Cone photoreceptors in the retina enable vision over a wide range of light intensities. However, the processes enabling cone vision in bright light (i.e. photopic vision) are not adequately understood. Chromophore regeneration of cone photopigments may require the retinal pigment epithelium (RPE) and/or retinal MĆ¼ller glia. In the RPE, isomerization of all-trans-retinyl esters (atRE) to 11-cis-retinol (11cROL) is mediated by the retinoid isomerohydrolase Rpe65. A putative alternative retinoid isomerase, dihydroceramide desaturase-1 (DES1), is expressed in RPE and MĆ¼ller cells. The retinol-isomerase activities of Rpe65 and Des1 are inhibited by emixustat and fenretinide, respectively. Here, we tested the effects of these visual cycle inhibitors on immediate, early and late phases of cone photopic vision. In zebrafish larvae raised under cyclic light conditions, fenretinide impaired late cone photopic vision, whereas emixustat-treated zebrafish unexpectedly had normal vision. In contrast, emixustat-treated larvae raised under extensive dark-adaption displayed significantly attenuated immediate photopic vision concomitant with significantly reduced 11-cis-retinaldehyde (11cRAL). Following 30 minutes of light, early photopic vision recovered, despite 11cRAL levels remaining significantly reduced. Defects in immediate cone photopic vision were rescued in emixustat- or fenretinide-treated larvae following exogenous 9-cis-retinaldehyde (9cRAL) supplementation. Genetic knockout of Des1 (degs1) or retinaldehyde-binding protein 1b (rlbp1b) did not eliminate photopic vision in zebrafish. Our findings define molecular and temporal requirements of the non-photopic or photopic visual cycles for mediating vision in bright light.European Commission Horizon 2020Irish Research CouncilNational Institutes of Health12 month embargo limited to 6 months due to H2020 - A
Novel digital food photos resource enhances knowledge of nutrition and dietetics students
A robust knowledge of food composition, the Australian food supply and cooking methods is integral to dietetics practice. Students learn these concepts across a variety of subjects, however a new dietetics subject in 2009 and a faculty based learning and teaching grant provided a timely opportunity to develop innovative new digital resources for students to enhance their food composition knowledge. One-hundred and sixty high quality digital food photographs were developed and nutrient composition data were added, before making the resource accessible to students via their eLearning sites. The primary aim of this study was to assess the views and experiences of first and fourth year students regarding the usefulness and application of the digital food photos resource in developing their food composition knowledge. The secondary aim was to identify and explore other potential applications of the resource and recommendations for future upgrades. Forty students completed an online survey and six took part in semi-structured qualitative interviews, which were facilitated by the same two researchers, before being digitally recorded and transcribed verbatim. Preliminary findings highlighted that students found the resource to be an interactive and valuable contributor to their knowledge, I loved it. I absolutely loved it. Like I sat on it for hours going through it (S1). All of the fourth year respondents said they would use the resource again, as did 83% of the first year students. A revised edition is currently being developed with 180 additional photographs and student feedback about further nutrients, symbols used and future commercial applications
Thymic output and CD4 T-cell reconstitution in HIV-infected children on early and interrupted antiretroviral treatment: evidence from the CHER trial.
Objectives: Early treatment of HIV-infected children and adults is important for optimal immune reconstitution. Infantsā immune systems are more plastic and dynamic than older childrenās or adultsā, and deserve particular attention. This study aimed to understand the response of the HIV-infected infant immune system to early antiretroviral therapy (ART) and planned ART interruption and re-start. Design: We used linear and nonlinear regression and mixed-effects models to describe childrenās CD4 trajectories and to identify predictors of CD4 count during early and interrupted ART. Methods: Data from HIV-infected children enrolled CHER trial, starting ART aged between 6 and 12 weeks, was used to explore the effect of ART on immune reconstitution. Results: Early treatment arrested the decline in CD4 count but did not fully restore it to the levels observed in HIV-uninfected children. Treatment interruption at 40 or 96 weeks resulted in a rapid decline in CD4 T-cells, which on retreatment returned to levels observed before interruption. NaĆÆve CD4 T-cell count was an important determinant of overall CD4 levels. A strong correlation was observed between thymic output and the stable CD4 count both before and after treatment interruption. Conclusions: Early identification and treatment of HIV-infected infants is important to stabilize CD4 counts at the highest levels possible. Once stabilized, childrenās CD4 counts appear resilient, with good potential for recovery following treatment interruption. The naĆÆve T-cell pool and thymic production of naive cells are key determinants of childrenās CD4 levels
Speciation control during Suzuki-Miyaura cross-coupling of haloaryl and haloalkenyl MIDA boronic esters
Boronic acid solution speciation can be controlled during the Suzuki-Miyaura cross-coupling of haloaryl MIDA boronic esters to enable the formal homologation of boronic acid derivatives. The reaction is contingent upon control of the basic biphase and is thermodynamically driven: temperature control provides highly chemoselective access to either BMIDA adducts at room temperature or BPin products at elevated temperature. Control experiments and solubility analyses have provided some insight into the mechanistic operation of the formal homologation process
