Southern Region Produce Safety Alliance Grower Training: Using Pre- and Post-Training Knowledge Assessments to Understand Training Effectiveness.

The Produce Safety Alliance (PSA) grower training was introduced in 2016 as the standardized curriculum to meet the training requirements of the Food and Drug Administration's (FDA) Food Safety Modernization Act's (FSMA) Produce Safety Rule (PSR). The PSR states that at least one supervisor or responsible party from each farm must have successfully completed this food safety training or one equivalent to the standardized curriculum, as recognized by the FDA. This study evaluated the effectiveness of PSA trainings conducted between 2017 and 2019 in the Southern United States by the Southern Regional Center for Food Safety Training, Outreach, and Technical Assistance by analyzing pre- and posttest assessments. Effectiveness was based on a 25-question knowledge assessment administered to participants before (n = 2494) and after (n = 2460) each training. The knowledge assessment indicated the overall effectiveness of the training, with average scores increasing significantly from pretest (15.9/25, 63.4%) to posttest (20.3/25, 81.3%) (P < 0.001). The greatest knowledge gains were seen in the Postharvest Handling and Sanitation, How to Develop a Farm Food Safety Plan, and Agricultural Water modules. Notably, these modules had lower posttest scores compared to the other modules, indicating that the amount of knowledge gained did not necessarily correspond with a sufficient understanding of the material. To ensure that participants understand all aspects of the PSR and best practices to minimize food safety risks, additional or advanced trainings may be needed. Additionally, the current testing instrument (pre-/posttest) used for PSA grower training, while validated, may not be optimal, thus alternative methods to assess the training effectiveness are likely needed.

Novel Digital Workflow for Nasoalveolar Molding and Postoperative Nasal Stent for Infants With Cleft Lip and Palate.

OBJECTIVE: We present a novel digital workflow to provide presurgical infant orthopedic (PSIO) treatment for a patient with a unilateral cleft lip/palate utilizing nasoalveolar molding (NAM) and a custom postsurgical nasal stent. SETTING: Within the US military healthcare system, the Joint Base San Antonio Craniofacial Anomalies Team utilizes dental scanners, predictive 3D modeling software, and 3D printing technology in a digital workflow for NAM appliance fabrication. WORKFLOW: Soft tissue facial scanning, peri-oral scanning, and dental putty impressions are used to facilitate fabrication and measure outcomes. Digital modeling software and 3D resin printing are utilized to manufacture the prescribed devices. MAIN OUTCOME MEASURES AND RESULTS: Extra-oral facial scans and intra-oral impressions are compared between 3 timepoints: pre-treatment, posttreatment with NAM, and postsurgical treatment. CONCLUSIONS: The ability to share workflows, establish outcome standards, and streamline patient care will continue to advance best practices in digital PSIO.

Wiring-up carbon single wall nanotubes to polycrystalline inorganic semiconductor thin films: low-barrier, copper-free back contact to CdTe solar cells.

We have discovered that films of carbon single wall nanotubes (SWNTs) make excellent back contacts to CdTe devices without any modification to the CdTe surface. Efficiencies of SWNT-contacted devices are slightly higher than otherwise identical devices formed with standard Au/Cu back contacts. The SWNT layer is thermally stable and easily applied with a spray process, and SWNT-contacted devices show no signs of degradation during accelerated life testing.

Predictors of change in fruit and vegetable consumption in a faith-based intervention with African American adults.

A majority of African American adults do not eat the recommended daily amount of fruit and vegetables. This study examined baseline demographic, health-related, and psychosocial variables as predictors of change in fruit and vegetable consumption from baseline to postprogram in a sample of church members taking part in a 15-month intervention. Participants who had a greater waist circumference, greater baseline fruit and vegetable consumption, greater leisure time physical activity, higher levels of social support, greater attendance at worship service, were obese, and did not have diabetes at baseline showed higher posttest fruit and vegetable consumption.

Cooks training for Faith, Activity, and Nutrition project with AME churches in SC.

PURPOSE: This study describes the development and evaluation of a participatory training for cooks in African American churches. The 8-h training focused on providing healthy meals within the church food program. It enlisted cooks in hands-on "cooking with the chef" training and menu building exercises, and demonstrated development of flavor in foods through healthy ingredients. Cook ratings from pre- to post-training (possible range: 1-10) were evaluated with the Wilcoxon signed rank test. RESULTS: 114 cooks from 57 churches over the period from 7/21/07 to 3/21/11 participated in trainings. Self-rated cooking skill increased from pre- (6.5±SD) to post-training (7.9±SD), p=0.0001. Self-rated confidence in preparing meals also increased significantly (pre: 7.3±SD; post: 8.3±SD), p=0001. Qualitative feedback from the cooks' training has been positive. Two of the more frequently stated changes cooks report are using less salt and using more vegetables and fruits in menus. Lessons learned include: choosing the right church to host the training, teamwork as a key component, need for support system for church cooks, allocation of time for planning as well as shopping for healthy ingredients, and incorporation of flexibility into the training plan.
