Image-Guided Thermal Ablation for Colorectal Liver Metastases.

Image-guided percutaneous thermal ablation is a widely acceptable local therapy for patients with colorectal liver metastases who are noneligible for surgery or present with recurrence after hepatectomy. The increasing knowledge of factors that affect oncologic outcomes has allowed selected patients with resectable small volume colorectal liver metastases to be treated by thermal ablation with curative intent. The continuous technological evolutions in imaging and image-guidance and the wide implementation of microwave ablation that overcomes most of the limitations of radiofrequency ablation have contributed to this paradigm shift. The importance of patient selection, ablation margin evaluation, and confirmation of complete tumor ablation (A0) are discussed in this article.

Survey of Dental Researchers' Perceptions of Sexual Harassment at AADR Conferences: 2015 to 2018.

The American Association for Dental Research (AADR) is committed to providing a collegial, safe, and welcoming environment for all. As part of this effort, we assessed perceptions and experiences related to sexual, gender-based, and non-gender-based harassment among registrants at AADR annual meetings from 2015 to 2018 (n = 10,495); examined demographic factors associated with reported experiences; and identified facilitators and potential solutions concerning these types of harassment. Registrants were emailed an invitation to an anonymous online survey. Demographics were assessed categorically, and response distributions to close-ended survey items were evaluated by these variables. Bivariate analyses of participant demographics were conducted with 8 types of perceived harassment. To determine the demographic distribution of reporters, along with bivariate associations among them, restricted analyses were performed among individuals reporting any type of harassment. Qualitative data analysts conducted content analysis of the open-ended responses to questions asking participants to reflect on the topic. Peer debriefing was used to refine the coding schema. A total of 824 responses were received, of which 172 individuals reported experiencing ≥1 of the 8 types of harassment surveyed. Among those, reports of condescending remarks occurred most frequently (70%). Reported harassment of a more sexual nature was less common by comparison. Reporters of harassment were more likely to be women, members of the AADR/CADR (Canadian Association for Dental Research) divisions, and/or frequent meeting attendees. A total of 229 respondents answered at least 1 of the open-ended questions. While the majority of survey respondents reported no personal experience with harassment at AADR meetings, the fact that 1 in 5 did should be cause for concern. In 2018, AADR introduced a "Professional Conduct at Meetings Policy" delineating unacceptable behaviors, including intimidating or harassing speech and actions. Results of this survey form an important baseline from which its impact may be monitored to ensure that future AADR meetings are respectful, supportive, and safe environments for all.

Healthy eating index is a predictor of early childhood caries.

Early childhood caries (ECC) is a preventable form of dental caries that affects very young children, particularly among low-income families and certain racial/ethnic minorities. The current study examined the relationship of dietary quality, as measured by the Healthy Eating Index (HEI), to the prevalence of ECC in 2- to 5-year-old children. Data from the Third National Health and Nutrition Examination Survey (NHANES III) were used for the study. We used logistic regression to compute adjusted odds ratios (OR) for ECC and 95% confidence intervals (CI). Children with the best dietary practices (uppermost tertile of the HEI) were 44% less likely to exhibit severe ECC compared with children with the worst dietary practices (lowest tertile of the HEI). A healthy eating pattern geared for promotion of optimal child development and prevention of chronic disease in later life may also reduce the risk of early childhood caries, particularly severe early childhood caries.
