- Background/Aims Traumatic dental injuries (TDI) are complex problems where lack of proper care may result in serious complications. The need to improve the management of TDI is a frequently addressed concern. Methods of improvement in their diagnosis and management are continuously evolving. The interactive Internet tool, the Dental Trauma Guide (DTG), helps to simplify diagnostic and management dilemmas. However, it is not a freely available tool. The aim of the current study was to assess the knowledge and diagnostic skills of undergraduate dental students with access to the DTG compared with students without such access, in order to validate and promote this tool in dental education. Materials and Methods Two groups of students were randomly selected where one group of final year dental undergraduate students were exposed to lectures, demonstrations, discussions and tutorials on the management of TDI according to the standard undergraduate curriculum in Sri Lanka. Another test group of 21 students were provided with access to DTG during their training in paediatric dentistry. At the end of the study period, students were assessed on their knowledge of TDI using MCQs (Multiple Choice Questions) and OSCEs (Objective Structured Clinical Examination), based on the DTG. Results The students with access to the DTG were more knowledgeable in providing the correct answers to three out of the seven OSCE questions. Evaluation based on the MCQs did not reveal a significant difference (p = .913). However, users of the DTG showed a statistically significant difference with better overall knowledge based on their answers (p = .028). Following this period of evaluation, all of the students were provided with access to the DTG to supplement their learning experience. Conclusion The Dental Trauma Guide is a useful supplementary tool for undergraduate students to arrive at a correct diagnosis and treatment plan for TDI.

- Nanostructure modification of dental implants has long been sought as a means to improve osseointegration through enhanced biomimicry of host structures. Several methods have been proposed and demonstrated for creating nanotopographic features; here we describe a nanoscale hydroxyapatite (HA)-coated implant surface and hypothesize that it will hasten osseointegration and improve its quality relative to that of non-coated implants. Twenty threaded titanium alloy implants, half prepared with a stable HA nanoparticle surface and half grit-blasted, acid-etched, and heat-treated (HT), were inserted into rabbit femurs. Pre-operatively, the implants were morphologically and topographically characterized. After 3 weeks of healing, the samples were retrieved for histomorphometry. The nanomechanical properties of the surrounding bone were evaluated by nanoindentation. While both implants revealed similar bone-to-implant contact, the nanoindentation demonstrated that the tissue quality was significantly enhanced around the HA-coated implants, validating the postulated hypothesis.

- A key developmental period for alcohol misuse is emerging adulthood (roughly ages 18–25). Personalized Feedback Interventions (PFI) are effective in reducing alcohol-related harmin college populations, however little research has evaluated PFIs given during high school.Moreover, cultural differences influence both alcohol misuse and response to interventions. The purpose of this study is to evaluate the efficacy of a web-based PFI given to high school seniors (ages 17-19) in the USA and Sweden. 1181 participants (42.3%male; 28.3%risky drinkers based on AUDIT-C) in the USA and 2171 in Sweden (44.1%male; 52.3% risky drinkers based on AUDIT-C) were assessed during their high school senior year. Approximately 1/3 were randomized to receive PFI. Approximately 1 week after viewing the PFI, participants were asked to complete a post-feedback satisfaction survey (3 subscales: information motivated change, shared information with friends, information was educational), and their “stage” on the readiness to change scale. Results showed 1) information motivated change subscale was associated with increases in contemplation and action stages of change and decreases in precontemplation; Swedish participants and those with higher AUDIT-C scores had lower scores; (2) USA sample was less likely to share information with friends; those with higher AUDIT-C scores were more likely to share information with friends; and (3) those with higher AUDIT-C scores were less likely to find information educational. Participants completed 6- and 12- month follow up surveys. After controlling for key baseline variables and using appropriate distributions for analyses, 6 month outcomes from 2236 participants (852 in USA; 1384 in Sweden; 731 received PFI), found those who received PFI drank significantly less alcohol per occasion (typical and peak), had lower blood alcohol concentration (typical and peak) and drank on fewer occasions than those who did not receive the PFI (effect size range: d = .12 to d = .22). There were no significant effects of PFI on alcohol-related problems or readiness to change and no significant interactions between country of residence and intervention on drinking outcomes. Results suggest web-based PFIs given during senior year of high school are efficacious in reducing alcohol use during transition to adulthood. Twelve-month outcomes and mediators will also be presented. This research was supported by NIAAA # 5R01AA018276 awarded to Drs. Larimer & Berglund.

- This observational study sought to improve our understanding of factors that contribute to risky sexual behavior among women seeking treatment for alcohol and other substance use disorders. Women were recruited at the start of outpatient (n=236) or inpatient (n=166) treatment. At intake, a Timeline Follow-back interview was used to obtain retrospective reports of daily drinking, drug use, and sexual behavior for a 90-day pre-treatment baseline period. Additional interview and questionnaire measures also were obtained. Measures were re- administered at four 90-day follow-up interviews. Among women who reported sex with a primary partner during baseline (n=261), 15% reported consistent condom use for all events with this partner, whereas 80% reported no condom use with this partner. Among women who reported sex with a non-primary partner (n=159; doesn’t include commercial sex trading), 26% reported consistent condom use and 45% reported no condom use with such partners. Significant correlates of non-use of condoms included negative beliefs and attitudes and low self-efficacy regarding condom use and AIDS prevention, as well as psychological distress, sexual impulsiveness and sensation seeking, history of severe assault by a male partner, and (with primary partners) negative partner attitudes toward condom use. Some of these correlates also predicted unprotected sex with a primary partner during the first 90 days after treatment entry, after controlling for baseline. However, unsafe sex with a non-primary partner during follow-up was most notably associated with follow-up levels of substance use, i.e., more drinks per drinking day and greater frequency of alcohol, marijuana, and cocaine use. In sum, preliminary analyses of baseline and follow-up data indicate a high prevalence of unprotected sex in this population. Identification of factors related to baseline and follow-up levels of risky behavior may suggest targets for future intervention development.

- The present study includes baseline data from 2867 students (77.8% from Sweden, 22.2% from US) and evaluates the relationships among self-reported disabilities, alcohol use, other substance use, and psychosocial adjustment. There were 114 (4.6%) ‘‘hard-of-hearing’’ (HH) students, 129 (5.2%) reported visual disabilities, 33 (1.3%) reported motor disabilities, 223 (9.0%) reported a reading/writing disability, and 97 (3.6%) reported they had ‘‘other’’ disabilities. Of these, 70 (14.1%) reported more than one disability. Presence of a disability was significantly higher among Sweden students (2 (1)=19.93, p< 0.001), with 19.1% of Sweden students and 11.5% of US students reporting at least one disability. Reporting any type of disability was associated with significantly greater alcohol use frequency, intensity, and related problems (all p < 0.02), significantly more mental health symptoms and conduct problems (p < 0.005), and significantly greater likelihood of illicit and prescription drug use (all p < 0.001). With respect to specific disabilities, individuals with motor disabilities reported the highest levels of alcohol use and mental health symptoms, whereas individuals who reported ‘‘other’’ disabilities had higher rates of illicit drug use and conduct problems. Further, there was a significantly positive correlation between the number of disabilities and intensity of alcohol use, mental health symptoms, conduct problems, illicit and prescription drug use, and alcohol related problems (all p < 0.001). The association between conduct problems and disability (any disability and number of disabilities) was moderated by country of origin, gender, and drinking for coping reasons on the Drinking Motives Questionnaire. Participants in Sweden, males, and those who drank for coping reasons were more likely to report a relationship between disability and conduct problems (p < 0.001). Participants who drank for coping reasons were also more likely to report a relationship between disability and alcohol related problems (p=0.001). These findings indicate students with disabilities are an important risk group for preventive interventions for alcohol, substance, and mental health problems, and may benefit from interventions which target healthy coping skills.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: The aim of this study was to evaluate the feasibility of using a person-centred ICT based intervention (F@CE) within multidisciplinary teams to increase the clients’ participation in everyday life after stroke in terms of study design and outcomes. The F@CE intervention was developed in collaboration with web developers and future users based on the Medical Research Council guidelines. A web-platform was created to provide a structure for the rehabilitation process and facilitate change by integrating a global problem solving strategy with SMS-reminders. Methods: 3 teams consisting of occupational therapists and physiotherapists working in neurological rehabilitation took part in 3 workshops including lectures, discussions and practical exercises. The participating teams then enrolled 10 clients with stroke that participated in the intervention. Goals were set using COPM and the clients scored their 3 goals each day during 8 weeks. Data was collected at inclusion, at 4 and 8 weeks using COPM, SIS, Self-Efficacy, LISAT-11, follow-up survey, daily ratings in the web-platform and by logbooks. Results: Response rates were 44–100% (mean 78%). Improvement was shown by COPM on both performance and satisfaction. In SIS 3.0 the items strength and ADL were those were the largest proportion of participants had improved at follow-up were strength and ADL/IADL (80 %) followed by memory, communication and mobility (70 %). Conclusion: All were satisfied with F@CE and the benefits of daily reminders of the goals which encouraged them to be more active. The only downside described was that they felt obligated to practice, although described as “a positive must”.

Effect of beta-to-alpha phase transition rate on corrosion behaviour of Zircaloy
- 2006

Tidskriftsartikel (refereegranskat)abstract
- The effect of β → α phase transition rate employed at the late stages of the fabrication process of Zircaloy-2 cladding tubes on the in-reactor corrosion behaviour is investigated. A cladding tube manufactured with a slower quenching exhibits a superior uniform corrosion resistance in boiling water reactors than the tube manufactured with a faster quenching. Scanning and transmission electron microscopy observations show that the slow β quench material has larger second phase particles and smaller particle number densities than the fast β quench material. It is argued that the larger SPPs with the lower number density survive the neutron irradiation field longer than the smaller ones. We have related the effective β quenching rate to the mean lamella grain size width, formed upon β quenching.
