Pilot Study to Assess the Effectiveness of the Sustainable Culturally Adaptive Nutrition Program (SCAN) to Improve Adherence to the National Diabetes Prevention Program.

PURPOSE: The Sustainable Culturally Adapted Nutrition Program (SCAN) is a novel adaptation to the National Diabetes Prevention Program (NDPP) that aims to improve attendance and effectiveness. This paper presents its feasibility and impact through the initial 6-month outcomes. DESIGN: A pragmatic quasi-experimental pilot study with intervention (DPP plus SCAN) and control (DPP only) groups. SAMPLES AND INCLUSION CRITERIA: Sustainable Culturally Adapted Nutrition Program participants were recruited from federally qualified health center (FQHC) clinic patients enrolled in a NDPP in Houston, Texas. Participants needed to be (1) ≥18 years old, (2) body mass index >25, (3) no prior diagnosis of diabetes, and (4) not pregnant. INTERVENTION: Sustainable Culturally Adapted Nutrition Program cooking classes were designed to teach skills to prepare fresh produce, and utilized Motivational Interviewing (MI) techniques to encourage participants to adapt these skills for foods that were culturally important to them. OUTCOME MEASURES: (1) National Diabetes Prevention Program attendance, (2) BMI and (3) percent weight loss. ANALYSIS: We used linear mixed models to test the association between weights and NDPP attendance. RESULTS: 22 intervention and 15 control participants completed the program to the 6-month point. Intervention participants had increased DPP attendance over controls (7.14 vs 6.87 session). Intervention participants also demonstrated on average, 1.5% weight loss for each additional SCAN class attended (P = .144). CONCLUSIONS: The SCAN adaptation shows promising results for effectively increasing both NDPP attendance and weight loss.

Application of implementation mapping to develop strategies for integrating the National Diabetes Prevention Program into primary care clinics.

Background: Diabetes is considered one of the most prevalent and preventable chronic health conditions in the United States. Research has shown that evidence-based prevention measures and lifestyle changes can help lower the risk of developing diabetes. The National Diabetes Prevention Program (National DPP) is an evidence-based program recognized by the Centers for Disease Control and Prevention; it is designed to reduce diabetes risk through intensive group counseling in nutrition, physical activity, and behavioral management. Factors known to influence this program's implementation, especially in primary care settings, have included limited awareness of the program, lack of standard clinical processes to facilitate referrals, and limited reimbursement incentives to support program delivery. A framework or approach that can address these and other barriers of practice is needed. Objective: We used Implementation Mapping, a systematic planning framework, to plan for the adoption, implementation, and maintenance of the National DPP in primary care clinics in the Greater Houston area. We followed the framework's five iterative tasks to develop strategies that helped to increase awareness and adoption of the National DPP and facilitate program implementation. Methods: We conducted a needs assessment survey and interviews with participating clinics. We identified clinic personnel who were responsible for program use, including adopters, implementers, maintainers, and potential facilitators and barriers to program implementation. The performance objectives, or sub-behaviors necessary to achieve each clinic's goals, were identified for each stage of implementation. We used classic behavioral science theory and dissemination and implementation models and frameworks to identify the determinants of program adoption, implementation, and maintenance. Evidence- and theory-based methods were selected and operationalized into tailored strategies that were executed in the four participating clinic sites. Implementation outcomes are being measured by several different approaches. Electronic Health Records (EHR) will measure referral rates to the National DPP. Surveys will be used to assess the level of the clinic providers and staff's acceptability, appropriateness of use, feasibility, and usefulness of the National DPP, and aggregate biometric data will measure the level of the clinic's disease management of prediabetes and diabetes. Results: Participating clinics included a Federally Qualified Health Center, a rural health center, and two private practices. Most personnel, including the leadership at the four clinic sites, were not aware of the National DPP. Steps for planning implementation strategies included the development of performance objectives (implementation actions) and identifying psychosocial and contextual implementation determinants. Implementation strategies included provider-to-provider education, electronic health record optimization, and the development of implementation protocols and materials (e.g., clinic project plan, policies). Conclusion: The National DPP has been shown to help prevent or delay the development of diabetes among at-risk patients. Yet, there remain many challenges to program implementation. The Implementation Mapping framework helped to systematically identify implementation barriers and facilitators and to design strategies to address them. To further advance diabetes prevention, future program, and research efforts should examine and promote other strategies such as increased reimbursement or use of incentives and a better billing infrastructure to assist in the scale and spread of the National DPP across the U.S.

Association of receiving opioid medication-assisted treatment with sexual identity and mental health/substance use disorder symptoms in a nationally representative sample of adults.

Background: Although the literature suggests that medication-assisted treatment (MAT) is an effective treatment for opioid use disorder, limited studies have assessed the prevalence or the association between MAT use and sexual identity, mental health, or substance use disorder among a nationally representative sample. We assessed the prevalence and association of opioid MAT use between sexual identity, depressive disorder symptoms, alcohol use dependence, and marijuana use dependence in the United States. Methods: We used the 2019 National Survey on Drug Use and Health public-use data on adults aged 18-64 years (N = 38,841) to conduct a weighted multivariable logistic regression analysis. Results: A total of 4.80% and 2.32% of the population identified as bisexual and lesbian/gay, respectively. About 0.31% (612,750 people) of the population reported receiving opioid MAT, 3.73% had alcohol use dependence, 1.42% had marijuana use dependence, and 9.13% had major depressive episode (MDE) symptoms. Of those who had received opioid MAT, 0.57% were bisexuals and 1.07% were lesbians/gays, 0.65% were people with alcohol use dependence, 2.32% with marijuana use dependence, and 1.59% with MDE symptoms. Lesbian/gay individuals were more likely to receive opioid MAT (AOR = 3.43, 95% CI = 1.42, 8.25) compared to heterosexual individuals. The odds were higher for people with marijuana use dependence (AOR = 3.44, 95% CI = 1.47, 8.06) and MDE symptoms (AOR = 5.22, 95% CI = 3.46, 7.89) than their counterparts. Conclusions: In this study, sexual minorities, people with MDE symptoms, and those dependent on marijuana use were more likely to receive opioid MAT, suggesting the need to investigate further opioid use disorder symptoms and their risk factors among these populations.

Performance of endoscopic ultrasound in staging rectal adenocarcinoma appropriate for primary surgical resection.

BACKGROUND & AIMS: Endoscopic ultrasound (EUS) often is used to stage rectal cancer and thereby guide treatment. Prior assessments of its accuracy have been limited by small sets of data collected from tumors of varying stages. We aimed to characterize the diagnostic performance of EUS analysis of rectal cancer, paying particular attention to determining whether patients should undergo primary surgical resection. METHODS: We performed a retrospective observational study using procedural databases and electronic medical records from 4 academic tertiary-care hospitals, collecting data on EUS analyses from 2000 through 2012. Data were analyzed from 86 patients with rectal cancer initially staged as T2N0 by EUS. The negative predictive value (NPV) was calculated by comparing initial stages determined by EUS with those determined by pathology analysis of surgical samples. Logistic regression models were used to assess variation in diagnostic performance with case attributes. RESULTS: EUS excluded advanced tumor depth with an NPV of 0.837 (95% confidence interval [CI], 0.742-0.908), nodal metastasis with an NPV of 0.872 (95% CI, 0.783-0.934), and both together with an NPV of 0.767 (95% CI, 0.664-0.852) compared with pathology analysis. Incorrect staging by EUS affected treatment decision making for 20 of 86 patients (23.3%). Patient age at time of the procedure correlated with the NPV for metastasis to lymph node, but no other patient features were associated significantly with diagnostic performance. CONCLUSIONS: Based on a multicenter retrospective study, EUS staging of rectal cancer as T2N0 excludes advanced tumor depth and nodal metastasis, respectively, with an approximate NPV of 85%, similar to that of other modalities. EUS has an error rate of approximately 23% in identifying disease appropriate for surgical resection, which is lower than previously reported.

Accuracy of endoscopic ultrasound in the diagnosis of T2N0 esophageal cancer.

BACKGROUND: Accurate staging of esophageal carcinoma (EC) is important since it directs further management. Endoscopic ultrasound (EUS) is the best tool available in the locoregional staging of EC; however, differentiating depth of tumor invasion (T) and nodal involvement (N) can be challenging. Accurate staging is particularly important to differentiate T1-2 N0 cancers, which can proceed directly to surgical resection versus TXN1 or T3N0/1 cancers, which benefit from induction chemoradiation prior to surgery. We report the accuracy of EUS staging for cT2N0 lesions. PATIENTS AND INTERVENTIONS: Six hundred six patients underwent EUS for staging of EC between October 2003 and February 2013 by a single interventional endoscopist specially trained in endoscopic ultrasound. Thirty-eight patients were diagnosed with T2N0 tumors and underwent surgical resection without preoperative chemoradiation. EUS staging was compared to surgical pathology to evaluate accuracy. Patient follow-up was obtained from a retrospective chart review. RESULTS: Thirty-eight patients (34 men, mean age 65.8 ± 10.5 years) with cT2N0 tumors by EUS underwent surgical resection of EC without chemoradiation after a mean of 22.4 ± 13.7 days post-EUS. When compared with final pathologic outcomes, 12 (32%) were understaged by EUS and 18 (47%) were overstaged. Understaging occurred due to tumor depth (T) in two patients (17%), nodal disease (N) in six (50%), and both in four (33%). Overstaging occurred due to pathology consistent with pT1b tumors instead of T2 tumors in all 17 cases. Based on EUS, 74% were referred for appropriate therapy. CONCLUSION: While EUS is highly accurate in staging EC, it is less accurate in staging tumors which are not on either ends of the spectrum (mucosally based or clearly transmural). In this challenging group of patients, EUS understaged EC in 32% of cases resulting in surgical resection when neoadjuvant chemoradiation may have been beneficial. We suspect that newer generation EUS systems, which provide better imaging, will result in improved accuracy in staging this group of patients.

The antibacterial effect of 2-octyl cyanoacrylate (Dermabond®) skin adhesive.

Dermabond® is a tissue adhesive commonly used for wound or surgical incision closure. Its use has previously been associated with a reduction in wound infection, and it has been thought to act as a physical barrier to bacteria accessing the wound. This study aimed to establish whether the Dermabond® adhesive demonstrated any intrinsic antimicrobial properties. Solidified pellets of Dermabond® were placed on standardised Agar plates cultured with a variety of pathogens. Inhibition of growth was demonstrated against Gram-positive bacteria. Culture swabs taken from the inhibition rings demonstrated no growth, suggesting that Dermabond has a bactericidal mechanism of action. Based on the design of this study, the results suggest that Dermabond® demonstrates bactericidal properties against Gram-positive bacteria. Its use for wound closure following surgical intervention may reduce postoperative wound infection by Gram-positive organisms.

Quadrilateral plate fractures of the acetabulum: an update.

Acetabular fractures with quadrilateral plate involvement form a heterogeneous group of fractures, which are not specifically defined by any current classification system. Their incidence is increasing due to the rising number of elderly osteoporotic fractures. They have always been notoriously difficult fractures to treat. We present a systematic review of conservative and operative management and their respective outcomes over the last century.

Comparison between endoscopic ultrasound and magnetic resonance imaging for the staging of pancreatic cancer.

OBJECTIVE: Preoperative staging of pancreatic cancer is crucial for proper therapy. Through this study, we aimed to compare the ability of endoscopic ultrasound (EUS) and magnetic resonance imaging (MRI) to effectively detect and stage pancreatic cancer. METHODS: One hundred twenty-seven patients undergoing EUS-fine-needle aspiration and MRI for the workup of pancreatic cancer were captured in a prospective database for comparison. The final surgical stage was recorded in patients who went to surgery. RESULTS: Of 127 patients, 48 were surgically explored, and of these, 22 (46%) underwent pancreaticoduodenectomy. Agreement in the patients' staging between EUS and MRI was 94 (74%) of 127. Magnetic resonance imaging was more likely to report metastatic disease or arterial involvement. The overall correlation between EUS and MRI was marginal (κ = 0.42; 95% CI, 0.26-0.58). Of the 48 surgically explored patients, 12 (25%) were understaged by MRI, 13 (27%) were understaged by EUS, and 1 (2%) were overstaged. Endoscopic US and MRI had a sensitivity of 34 (97.2%) of 35 for stage II tumors and 35 (100%) of 35 for lower-stage tumors, respectively. CONCLUSION: Endoscopic US and MRI had marginal correlation for staging, especially the more advanced tumors. Although EUS has the added advantage of tissue acquisition for confirmation, the tumors understaged by both the modalities were different. Therefore, both tests should be performed for accurate staging.

Presence of lymph node vasculature: a new EUS criterion for benign nodes?

OBJECTIVES: Lymph nodes normally have prominent centrally located blood vessels, which may become obliterated with tumor infiltration. The presence of intranodal vasculature has been noted to coincide with benign cytology. We sought to determine the test characteristics of the presence of intranodal mediastinal vasculature during endoscopic ultrasound (EUS). METHODS: 67 mediastinal lymph nodes evaluated by EUS in 66 patients over a 1-year period were evaluated for the presence of intranodal vasculature, which was considered benign when it traversed through the node without disruption. RESULTS: Of the 67 lymph nodes evaluated, 29 (43%) were found to be malignant on cytopathologic review. Benign vascular markings were present in 15/67 (22.4%) lymph nodes evaluated. All 15 (100%) of these nodes were found to have benign fine-needle aspiration (FNA) results. The presence of benign vasculature had a negative predictive value of 100%. CONCLUSIONS: The presence of intranodal vasculature was universally associated with a benign diagnosis. The addition of this EUS finding improves the ability to characterize lymph nodes and predict the likelihood of malignant involvement.

Does FDG-PET add information to EUS and CT in the initial management of esophageal cancer? A prospective single center study.

PURPOSE: There is no algorithm for the initial staging of esophageal cancer that is considered standard of care. This prospective blinded study analyzes the utility of FDG-PET as an adjunct to EUS and CT for the management of patients with esophageal cancer. METHODS: Between December 2003 and October 2006, patients diagnosed with esophageal carcinoma underwent EUS, CT, and FDG-PET at their initial evaluation. Two thoracic surgeons were given staging EUS results and CT scan reports. They were asked if the patient needed surgical resection, neoadjuvant chemotherapy followed by resection, or palliation. With each case, one surgeon was unblinded to the FDG-PET results. The treatment decisions of each surgeon were compared to determine if PET altered clinical management. RESULTS: A total of 50 patients (45 male, 5 female) were enrolled and data were prospectively collected. Forty-three (86%) had adenocarcinoma and 7 (14%) had squamous cell carcinoma. EUS was completed in 88% (44) of cases while 6 (12%) were incomplete secondary to tight stenosis. Nineteen were treated with surgery, 25 with neoadjuvant chemotherapy and surgery, and 6 with palliative chemoradiation. In 49 of 50 patients, the surgeons came to identical management decisions independent of PET results. In the one case that the treatment decision differed, the EUS was incomplete. The agreement on treatment strategy was 98% (kappa= 0.97, 95% CI 0.93-0.99). CONCLUSION: This study shows that the addition of FDG-PET to EUS and CT offers little information to the initial treatment stratification of patients with esophageal cancer. However, in patients with incomplete EUS, FDG-PET may have some clinical utility.

EUS-FNA as the initial diagnostic modality in centrally located primary lung cancers.

BACKGROUND AND AIMS: The need to safely and accurately diagnose lung neoplasms is crucial as the only prospect for a cure is surgical resection. A small amount of data exists on the use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) as the initial diagnostic modality of primary lung cancer. METHODS: We performed a retrospective review of an established prospective database of all patients undergoing EUS-FNA of a primary lung neoplasm adjacent to the esophagus during January 2001 to August 2005 in one tertiary care center. The indications for the procedure, diagnostic accuracy, and complications were reviewed. RESULTS: A total of 17 cases (9 females, 8 males) were identified. The mean age was 66 (SD 10.6). There were 9 lesions within the hilum and 8 lesions within the upper lobes. The median size of the lung lesions was 5 (range 2 to 12)x4 (range 2 to 9) cm. The median and mean number of FNA passes was 3. All the procedures provided an accurate diagnosis of the primary lung lesion without need for further intervention. One patient with active hemoptysis was transiently hospitalized for aspiration pneumonia postprocedure. CONCLUSIONS: EUS-FNA is a safe, relatively cost-effective, and accurate initial diagnostic modality for the diagnosis of lung lesions adjacent to the esophagus or invading the mediastinum. Although further randomized prospective trials are warranted, this modality should be considered as a first step in the diagnostic armamentarium in centrally located lung lesions.

The level of carcinoembryonic antigen and the presence of mucin as predictors of cystic pancreatic mucinous neoplasia.

OBJECTIVES: Characterization of pancreatic cysts using endoscopic ultrasound-guided fine-needle aspiration includes cytological interpretation and chemical analysis. We prospectively analyzed the contribution of carcinoembryonic antigen (CEA) and cytological identification of extracellular mucin as predictors of mucinous neoplasia and malignancy. METHODS: From January 2003 to October 2005, all patients referred to the University of Virginia with cystic lesions of the pancreas underwent endoscopic ultrasound-guided fine-needle aspiration with cytological evaluation and CEA level analysis. Data were collected prospectively and confirmed by resection or tissue biopsy. Univariate and multivariate analyses were performed on the following variables with regard to their ability to predict mucinous neoplasia: age (<55 or >55 years), sex, CEA level (<300 or >300 ng/mL), and cytological appreciation of extracellular mucin (positive or negative). P values less than 0.05 were considered significant. RESULTS: A total of 43 patients were included in this study. There were 19 men and 24 women with a mean age of 63 +/- 14 years. The only complication was pancreatitis secondary to cyst leak in one patient. Multivariate analysis confirmed CEA level greater than 300 ng/mL (P= 0.007) and the identification of mucin (P < 0.001) as significant predictors. CONCLUSIONS: With pancreatic cyst fluid analysis, the strongest predictor of mucinous neoplasia is the presence of identifiable mucin, followed by a CEA level greater than 300 ng/mL. The workup of cystic lesions of the pancreas should include chemical analysis for the CEA level and cytological examination with particular attention to extracellular mucin.
