Clean Water for Less Integrated Planning Reduces the Cost of Meeting Water Quality Goals in New Hampshire

Rising populations and increased development in New Hampshire coastal communities have led to a decline in water quality in the Great Bay Estuary. Responding effectively and affordably to new federal permit requirements for treating and discharging stormwater and wastewater will require innovative solutions from communities in the area. The Water Integration for Squamscott-Exeter (WISE) project developed an integrated planning framework through which the coastal communities of Exeter, Stratham, and Newfields could significantly reduce the cost of meeting permit requirements. In this brief, authors Alison Watts, Robert Roseen, Paul Stacey, Renee Bourdeau, and Theresa Walker report that integrated planning could save these communities over $100 million (in fifty-year lifecycle costs) by prioritizing high-impact, low-cost mitigation strategies across permit type and town boundaries. The project, which has received an Environmental Merit award from Environment Protection Agency, also found that attainment of water quality standards in the Exeter–Squamscott River will not be possible without substantial cooperation and investment from upstream communities, which are not currently subject to EPA permit requirements. Collaboration among communities in planning and implementing projects to meet clean water regulations can have significant cost and effectiveness benefits

Clean Water for Less

Rising populations and increased development in New Hampshire coastal communities have led to a decline in water quality in the Great Bay Estuary. Responding effectively and affordably to new federal permit requirements for treating and discharging stormwater and wastewater will require innovative solutions from communities in the area. In March 2015, the Water Integration for Squamscott–Exeter (WISE) project completed an integrated planning framework through which the coastal communities of Exeter, Stratham, and Newfields could more affordably manage permits for wastewater and stormwater. However, meeting maximum goals for nitrogen reduction will require collaboration and commitment from all municipalities in the watershed, whether regulated under the Clean Water Act or not

VCU-UNITE: Identifying Recognition Mechanisms for University-Community Engagement

The aims of the project were to determine what process would be appropriate to recognize significant contributions of university and community partners to joint community engagement projects. Our view was that several different award ceremonies exist in VCU, none of which are well attended and suggesting that this form of recognition may not be a high priority for participants. Thus, we sought to determine the awareness and extent of involvement of VCU faculty, staff and students in community engagement projects, and to find out what format of recognition process would be appealing to both university and community participants. We gathered this information through surveys and focus groups, analyzed the data and determined that university and community partners had differing views on what types of recognition would be desirous. Next, we designed a web portal through which nominations could be made by members of the university and by the community. We propose a streamlined nomination and online review process, leading to a quarterly award consisting of a letter of thanks from the Division of Community Engagement, and a photograph and narrative placed on the VCU website. Recipients of quarterly awards would automatically compete for an annual award, such as P&T credit or additional community leave time (university), or a scholarship, a plaque, or recognition at a VCU event (community)

How AP CS A Matches College Courses

ABSTRACT The Advanced Placement (AP) Program provides a framework for high school students to obtain college credit and/or placement for work done in high school. Toward this end, the College Board outlines course descriptions and organizes examinations in several dozen disciplines, including computer science. To meet its goals, each AP course must align with college courses, so students taking an AP course will master needed content Several approaches are used to monitor this connection between AP courses and collegelevel courses. This session will review these approaches, considering how the AP CS A course matches introductory college computer science courses

The effect of oncoplastic reduction on the incidence of post-operative lymphedema in breast cancer patients undergoing lumpectomy

Purpose: In breast cancer patients with macromastia, breast conservation surgery (BCS) followed by radiation therapy (RT) may be associated with a different complication profile than those without macromastia. Oncoplastic reduction mammoplasty (ORM) aims to reduce breast volume while excising the tumor bed and its margins. Since breast volume was found to be a risk factor for chronic breast lymphedema, this study was performed to determine the impact of ORM on chronic breast lymphedema as well as other complications compared to BCS without ORM. Material & Methods: We performed a retrospective chart review on patients who underwent lumpectomy with RT from 2014 to 2018. Chronic breast lymphedema (CBL) was defined as swelling that persisted \u3e1 year post-RT. Breast volumes (BV) were determined by contoured breast volumes or, if unavailable, estimated by the 95% isodose volumes from the RT treatment planning system. Univariate analysis was used to evaluate patient factors and treatment outcomes in women with BV ≥1300 cc compared to-Evaluate factors associated with ≥1 complication. Identify factors associated with the development of CBL. Results: The total population included 1173 patients: -1122 (95.7%) underwent BCS alone without ORM -51 (4.3%) underwent ORM -733 (62.5%) had a BVcc -440 (37.5%) had BV ≥1300 cc Multivariate regression analysis demonstrated that compared to patients with BV \u3c 1300 cc, patients with BV ≥1300 cc had: -Higher BMI (OR=1.200, P\u3c0.001) -Increased risk of CBL (OR=2.127, P=0.024) -Decreased risk of grade 2 radiation dermatitis (OR=0.457, P=0.002) Conclusion: Our data demonstrates that patients with breast volumes ≥1300 cc were two times more likely to develop CBL. Although patients with ORM had an increased risk for surgical site complications, the ORM procedure may have mitigated their risk for CBL. ORM should be considered at the time of BCS in women with macromastia to reduce their future risk of CBL as there is no cure for this disease.https://scholarlycommons.henryford.com/sarcd2021/1008/thumbnail.jp

Jumping into the deep-end: results from a pilot impact evaluation of a community-based aquatic exercise program

This multi-center quasi-experimental pilot study aimed to evaluate changes in pain, joint stiffness, physical function, and quality of life over 12 weeks in adults with musculoskeletal conditions attending ‘Waves’ aquatic exercise classes. A total of 109 adults (mean age, 65.2 years; range, 24–93 years) with musculoskeletal conditions were recruited across 18 Australian community aquatic centers. The intervention is a peer-led, 45 min, weekly aquatic exercise class including aerobic, strength, flexibility, and balance exercises (n = 67). The study also included a control group of people not participating in Waves or other formal exercise (n = 42). Outcomes were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and EuroQoL five dimensions survey (EQ-5D) at baseline and 12 weeks. Satisfaction with Waves classes was also measured at 12 weeks. Eighty two participants (43 Waves and 39 control) completed the study protocol and were included in the analysis. High levels of satisfaction with classes were reported by Waves participants. Over 90 % of participants reported Waves classes were enjoyable and would recommend classes to others. Waves participants demonstrated improvements in WOMAC and EQ-5D scores however between-group differences did not reach statistical significance. Peer-led aquatic exercise classes appear to improve pain, joint stiffness, physical function and quality of life for people with musculoskeletal conditions. The diverse study sample is likely to have limited the power to detect significant changes in outcomes. Larger studies with an adequate follow-up period are needed to confirm effects

A Transcriptional “Scream” Early Response of E. coli Prey to Predatory Invasion by Bdellovibrio

We have transcriptionally profiled the genes differentially expressed in E. coli prey cells when predatorily attacked by Bdellovibrio bacteriovorus just prior to prey cell killing. This is a brief, approximately 20–25 min period when the prey cell is still alive but contains a Bdellovibrio cell in its periplasm or attached to and penetrating its outer membrane. Total RNA was harvested and labelled 15 min after initiating a semi-synchronous infection with an excess of Bdellovibrio preying upon E. coli and hybridised to a macroarray spotted with all predicted ORFs of E. coli. SAM analysis and t-tests were performed on the resulting data and 126 E. coli genes were found to be significantly differentially regulated by the prey upon attack by Bdellovibrio. The results were confirmed by QRT-PCR. Amongst the prey genes upregulated were a variety of general stress response genes, potentially “selfish” genes within or near prophages and transposable elements, and genes responding to damage in the periplasm and osmotic stress. Essentially, the presence of the invading Bdellovibrio and the resulting damage to the prey cell elicited a small “transcriptional scream”, but seemingly no specific defensive mechanism with which to counter the Bdellovibrio attack. This supports other studies which do not find Bdellovibrio resistance responses in prey, and bodes well for its use as a “living antibiotic”

Genome Degradation in Brucella ovis Corresponds with Narrowing of Its Host Range and Tissue Tropism

Brucella ovis is a veterinary pathogen associated with epididymitis in sheep. Despite its genetic similarity to the zoonotic pathogens B. abortus, B. melitensis and B. suis, B. ovis does not cause zoonotic disease. Genomic analysis of the type strain ATCC25840 revealed a high percentage of pseudogenes and increased numbers of transposable elements compared to the zoonotic Brucella species, suggesting that genome degradation has occurred concomitant with narrowing of the host range of B. ovis. The absence of genomic island 2, encoding functions required for lipopolysaccharide biosynthesis, as well as inactivation of genes encoding urease, nutrient uptake and utilization, and outer membrane proteins may be factors contributing to the avirulence of B. ovis for humans. A 26.5 kb region of B. ovis ATCC25840 Chromosome II was absent from all the sequenced human pathogenic Brucella genomes, but was present in all of 17 B. ovis isolates tested and in three B. ceti isolates, suggesting that this DNA region may be of use for differentiating B. ovis from other Brucella spp. This is the first genomic analysis of a non-zoonotic Brucella species. The results suggest that inactivation of genes involved in nutrient acquisition and utilization, cell envelope structure and urease may have played a role in narrowing of the tissue tropism and host range of B. ovis

Risk Factors for Colorectal Cancer in Patients with Multiple Serrated Polyps: A Cross-Sectional Case Series from Genetics Clinics

Patients with multiple serrated polyps are at an increased risk for developing colorectal cancer (CRC). Recent reports have linked cigarette smoking with the subset of CRC that develops from serrated polyps. The aim of this work therefore was to investigate the association between smoking and the risk of CRC in high-risk genetics clinic patients presenting with multiple serrated polyps. Methods and Findings We identified 151 Caucasian individuals with multiple serrated polyps including at least 5 outside the rectum, and classified patients into non-smokers, current or former smokers at the time of initial diagnosis of polyposis. Cases were individuals with multiple serrated polyps who presented with CRC. Controls were individuals with multiple serrated polyps and no CRC. Multivariate logistic regression was performed to estimate associations between smoking and CRC with adjustment for age at first presentation, sex and co-existing traditional adenomas, a feature that has been consistently linked with CRC risk in patients with multiple serrated polyps. CRC was present in 56 (37%) individuals at presentation. Patients with at least one adenoma were 4 times more likely to present with CRC compared with patients without adenomas (OR = 4.09; 95%CI 1.27 to 13.14; P = 0.02). For females, the odds of CRC decreased by 90% in current smokers as compared to never smokers (OR = 0.10; 95%CI 0.02 to 0.47; P = 0.004) after adjusting for age and adenomas. For males, there was no relationship between current smoking and CRC. There was no statistical evidence of an association between former smoking and CRC for both sexes. Conclusion A decreased odds for CRC was identified in females with multiple serrated polyps who currently smoke, independent of age and the presence of a traditional adenoma. Investigations into the biological basis for these observations could lead to non-smoking-related therapies being developed to decrease the risk of CRC and colectomy in these patients.Daniel D.
