The Impact of an Education Intervention to Improve Blood Pressure Control among Black Non-Hispanic Patients and Hispanic Patients with Chronic Kidney Disease.

This project examined the effect of an educational intervention on blood pressure control among minority patients with chronic kidney disease (CKD). Adherence to a low-sodium diet is crucial for blood pressure control. It is also vital to assess food insecurity to improve diet adherence, especially among high-risk underrepresented populations. Participants were recruited from a public hospital renal clinic. Knowledge and food access was assessed using CKD and food insecurity questionnaires. Food frequency and 24-hour 3-day food diaries were completed and analyzed. Eighteen patients were enrolled (Black, non-Hispanic = 66.6%, Hispanic = 27.7%, uninsured = 33.3%, and Medicaid recipients = 27.7%). Eighty-nine percent of participants screened positive for food insecurity and received vouchers for healthy food from a food depository. Paired t tests showed statistically significant increase in knowledge (p < 0.00) and self-efficacy, and systolic blood pressure improved post-intervention. This study suggests that Black non-Hispanic and Hispanic patients with CKD have limited access to healthy food and consume higher sodium. Patient education, screening for food insecurity, and access to a food depository enhanced adherence to low sodium diet and improved blood pressure control.

Concordance of breast cancer biomarker testing in core needle biopsy and surgical specimens: A single institution experience.

BACKGROUND: Accurate diagnostic biomarker testing is crucial to treatment decisions in breast cancer. Biomarker testing is performed on core needle biopsies (CNB) and is often repeated in the surgical specimen (SS) after resection. As differences between CNB and SS testing may alter treatment decisions, we evaluated concordance between CNB and SS as well as associated changes in treatment and clinical outcomes. METHODS: We performed a retrospective analysis of breast cancer patients at our institution between January 2010 and May 2020. Concordance between CNB and SS was assessed for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Survival in patients, including recurrence, metastatic recurrence, and death, were assessed using chi-squared likelihood ratio. RESULTS: In total, 961 patients met eligibility criteria. Concordance, minor discordance, total concordance (concordance plus minor discordance), and major discordance between CNB and SS were reported for ER (87.7%, 9.2%, 90.8%, and 2.9%), PR (58.1%, 29.1%, 87.2%, and 12.8%), and HER2 IHC (52.5%, 20.9%, 73.4%, 26.6%), respectively. HER2 FISH concordance and major discordance were 58.5% and 1.2%, respectively. Of major discordance, ER (48.2%, p < 0.001) and HER2 FISH (50.0%) led to more management changes than HER2 IHC (2.4%, p = 0.04) and PR (1.6%, p = 0.10). Patients with ER major discordance had increased risk of death (6.7% concordance vs. 22.2% major discordance, p = 0.004). CONCLUSION: Overall, retesting ER and HER2 was more clinically beneficial than retesting PR. To aid decision-making and minimize healthcare costs, we propose patient-centered guidelines on retesting biomarker profiles.

Impact of a nutrition education program on health behaviors in a university workplace wellness program.

BACKGROUND: Obesity is a complex health issue associated with the leading causes of preventable chronic diseases, such as heart disease and type 2 diabetes. As part of an interprofessional team, nurse practitioners can play an integral role in leading worksite interventions to enhance health behavior change. Although worksite nutrition interventions have existed for many years, effective weight management programs are needed in the workplace. PURPOSE: The purpose of this study was to determine the effect of a novel nutrition education program implemented in the workplace on health behaviors (dietary habits and physical activity), motivators and barriers, emotional eating, confidence, and biometrics (body mass index and lipid levels). METHODS: A total of 96 university employees participated in a one-group pre- and postintervention from 2017 to 2019. The intervention included eight weekly face-face education sessions. We assessed dietary habits, physical activity, motivators and barriers of a healthy lifestyle, emotional eating, confidence levels, body mass index, and lipid levels. Descriptive statistics, chi-square test, one-way analysis of variance, and Wilcoxon rank test were performed. RESULTS: The consumption of fruits, vegetables, beans, grains, and physical activity increased significantly. Barriers, body mass index, and triglycerides significantly decreased. There was no significant difference in emotional eating and motivators after the intervention. IMPLICATIONS FOR PRACTICE: Nurse practitioners are positioned to lead an interprofessional team to provide nutrition education to help mitigate risk factors for obesity in various settings, including the workplace.

Heart dose and coronary artery calcification in patients receiving thoracic irradiation for lung cancer.

BACKGROUND: Thoracic irradiation (TIR) is associated with an increased risk of coronary artery disease (CAD) and coronary-related death. Lung cancer patients receive considerable doses of TIR, making them a high-risk population that may benefit from post-therapy surveillance. Coronary artery calcium (CAC) is a known biomarker of CAD development and may serve as a useful indicator of disease progression in this population. We hypothesized greater CAC progression in lung cancer patients subjected to higher whole heart radiation doses. METHODS: CAC progression (pre- and >2 years post-TIR) from chest CT scans of lung cancer patients were evaluated. A 2:1 matched control population was established controlling for age, gender, race, and CT scan interval. Vessel-specific CAC presence, progression, and extension in pre- and post-interval CT studies was evaluated by two blinded reviewers using the ordinal method. Dosimetric treatment files were restored and contours of the whole heart and proximal left anterior descending artery (LAD) were created within existing plans to compute radiation doses (Pinnacle Treatment Planning Software). Binary logistic regression analysis identified factors predictive for CAC development. Multiple logistic regression analysis with hierarchal method was used to assess covariates. RESULTS: Thirty-five patients and 65 controls (50% female) were evaluated; mean age 57 years, mean follow-up post-radiation 4.9±2.2 years. Average mean and maximum left anterior descending coronary artery (LAD) radiation doses were 19.9 Gy (95% CI, 14.1-25.7) and 30.7 Gy (95% CI, 23.8-37.5), respectively; 91.6% inter-observer variability. There was greater incidence of coronary calcification in irradiated patients (48.6% vs. 24.6%; P=0.01). In interval CT scans, a greater proportion of radiated patients demonstrated new coronary calcification (P=0.007) and extension within the LAD (P=0.003). Radiation exposure was the only independent predictor of new calcification (OR 3.1; 95% CI: 1.09-9.2). CONCLUSIONS: We identified both an increase in the development and progression of CAC in lung cancer patients receiving TIR. Future studies utilizing alternative cancer populations and larger sample sizes are necessary to further correlate radiographic and dosimetric observations to cardiovascular events.

Delivery of a community-based nutrition education program for minority adults.

BACKGROUND AND PURPOSE: Chronic diseases such as heart disease, type 2 diabetes, and obesity disproportionately affect minority adults, including African Americans. Engaging in lifestyle changes such as improving dietary habits and increasing physical activity can decrease the incidence and severity of these chronic diseases. The purpose of this research study was to explore the impact of a nutrition education program on health behaviors, lifestyle barriers, emotional eating, and body mass index (BMI) in a community-based setting with a minority sample. METHODS: A convenience sample of 47 primarily African American adults participated in two similar Full Plate Diet nutrition interventions for 6 weeks (group I) and 8 weeks (group II). Participants completed pre-assessment and post-assessment of fruit, vegetable, and fat intake, as well as pre-assessment and post-assessment on physical activity, healthy lifestyle barriers, emotional eating, and BMI. CONCLUSIONS: After intervention, there was a significant increase in intake of fruits and vegetables and decreased fat intake. No significant differences were found in physical activity, healthy lifestyle barriers, emotional eating, or BMI after the intervention. IMPLICATIONS FOR PRACTICE: A structured, community-based nutrition education program may result in improved dietary habits among African Americans.

Vibratory sense deficits in patients with symptomatic femoroacetabular impingement.

OBJECTIVE: Sensory deficits, measured through vibratory perception threshold (VPT), have been recognized in hip and knee osteoarthritis (OA), but have not been evaluated in femoroacetabular impingement (FAI), thought to be a pre-OA condition. This study aimed to assess VPT in symptomatic FAI pre- and 6-months post-arthroscopy vs. METHODS: FAI patients and controls were assessed for VPT at the first metatarsophalangeal joint. Pain was assessed using a visual analog pain scale. FAI participants were evaluated again 6-months after surgery for FAI. Differences between groups and pre- and post- surgery were evaluated with independent and paired sample t-tests, respectively. Secondary analysis was performed using repeated-measures ANOVA to evaluate the effect of pain and time since surgery on VPT pre- and post-operatively. RESULTS: No differences in age and BMI were seen between groups (p>0.05). Reduced VPT (higher value is worse) was evident in the pre- (8.0±3.9V, t=2.81, p=0.009) and post-operative (6.8±2.8V, t=2.34, p=0.027) patients compared to controls (4.7±1.3V). After hip arthroscopy, there was a trend toward improved VPT (t=1.97, p=0.068). Preoperative and 6-months postoperative pain and time since surgery were not found to influence VPT (F-ratio⋝0.00, p⋝0.427). CONCLUSION: Sensory deficits were observed in FAI patients both before and 6-months after hip arthroscopy.

Effect of hospice nonprofessional caregiver barriers to pain management on adherence to analgesic administration recommendations and patient outcomes.

Nonprofessional caregivers frequently experience barriers to using analgesics for pain in patients in home hospice settings, and patients in pain may suffer needlessly. For example, caregiver adherence to the administration of analgesics is lower for as-needed (PRN) regimens than for standard around-the-clock regimens. But little is known about the barriers caregivers experience and the effects of those barriers. Accordingly, we determined caregiver barriers to using analgesics to manage the pain of patients in the home hospice care setting, and how such barriers affected caregiver adherence and patient quality of life. To this end, we measured barriers, caregiver adherence to PRN analgesic regimens, and patient health outcomes (pain, depression, quality of life [QoL]). A 3-day longitudinal design was used. We recruited 46 hospice nonprofessional caregiver-patient dyads from a local community hospice agency. Barriers were measured with the Barrier Questionnaire II. Adherence to the PRN analgesic regimen was obtained with a 3-day pain and medication diary. Patient outcome measures included pain intensity, the Hospital Depression Scale, and the Brief Hospice Inventory for QoL. Barrier scores were moderate to low. Caregivers adhered to PRN analgesic regimens approximately 51% of the time. Higher caregiver adherence to PRN analgesic regimens was associated with lower patient pain intensity and higher patient QoL, but not, surprisingly, with barriers to pain management. Longitudinal studies are now needed to identify factors besides caregiver barriers that may unduly lower caregiver adherence to PRN analgesic regimens.

NBME subject examination in surgery scores correlate with surgery clerkship clinical experience.

OBJECTIVE: Most medical schools in the United States use the National Board of Medical Examiners Subject Examinations as a method of at least partial assessment of student performance, yet there is still uncertainty of how well these examination scores correlate with clinical proficiency. Thus, we investigated which factors in a surgery clerkship curriculum have a positive effect on academic achievement on the National Board of Medical Examiners Subject Examination in Surgery. DESIGN: A retrospective analysis of 83 third-year medical students at our institution with 4 unique clinical experiences on the general surgery clerkship for the 2007-2008 academic year was conducted. Records of the United States Medical Licensing Examination Step 1 scores, National Board of Medical Examiners Subject Examination in Surgery scores, and essay examination scores for the groups were compared using 1-way analysis of variance testing. SETTING: Rush University Medical Center, Chicago IL, an academic institution and tertiary care center. RESULTS: Our data demonstrated National Board of Medical Examiners Subject Examination in Surgery scores from the group with the heavier clinical loads and least time for self-study were statistically higher than the group with lighter clinical services and higher rated self-study time (p = 0.036). However, there was no statistical difference of National Board of Medical Examiners Subject Examination in Surgery scores between the groups with equal clinical loads (p = 0.751). CONCLUSIONS: Students experiencing higher clinical volumes on surgical services, but less self-study time demonstrated statistically higher academic performance on objective evaluation, suggesting clinical experience may be of higher value than self-study and reading.

Frequency of adjustments and weight loss after laparoscopic adjustable gastric banding.

Laparoscopic adjustable gastric banding is an effective procedure for weight loss. Long-term follow-up and band adjustments are crucial to achieve sustained weight loss, but the optimal frequency is unknown. We compare the weight loss of two patient groups adjusted at different frequencies. A 24-month analysis was conducted to 280 patients (156 from an academic center and 124 from an outpatient surgery center). Each center's patients were stratified into 6-month groups according to the length of follow-up. These groups were compared between the settings for average adjustments per month and percent excess weight loss (%EWL). Patient subgroup 0-6 months had 0.6 adjustments/month (adj/mo) and 18.3% EWL at AC compared to 0.7 adj/mo and 19.1% EWL at OC. Subgroup 6-12 months had 0.4 adj/mo and 27.2% EWL at AC compared to 0.5 adj/mo and 33.4% EWL at OC. Subgroup 12-18 months had 0.3 adj/mo and 25.3% EWL at AC compared to 0.5 adj/mo and 45.6% EWL at OC. Subgroup 18-24 months had 0.3 adj/mo and 30.9% EWL at AC compared to 0.3 adj/mo and 42.2% EWL at OC. Analysis of variance crossing 6-month groups with facility produced significant effects for groups (F = 15.52, df = 4.290, p < 0.001), center (F = 14.28, df = 1.290, p < 0.001), and the center-by-group interaction (F = 3.01, df = 4.290, p < 0.02). Our data suggest that more frequent adjustments result in increased EWL, but optimal frequency remains unknown. We believe that the difference noted between the clinics stems from accessibility to adjustments. Additional data, such as %EWL at smaller monthly intervals and the point of diminishing results, should be investigated in future studies.

Factors of breast cancer screening among Korean immigrants in the United States.

The purpose of this paper is to assess breast cancer screening rates and explore factors related to all three measures of breast cancer screening, mammography, clinical breast examination (CBE), and breast self-examination (BSE), among Korean immigrants in the United States. A telephone survey was conducted with 189 Korean women aged 40 and older in Cook County, Illinois. Of this group, 78% had had a mammogram at some point, and 38.6% had had one within the previous year. Fifty-three percent had had a CBE, while 26.1% had had one within the previous year. Whereas 58.1% had examined their breasts before, 46.3% did monthly BSE. Korean women's breast cancer screening rates are improving even though the rates are still lower than screening rates in the United States. Having a regular check-up and being married were strongly related to all three measures of cancer screening. Further in-depth research is suggested to understand KA women's perspectives on having access to care.

Morning melatonin has limited benefit as a soporific for daytime sleep after night work.

Exogenous melatonin administration in humans is known to exert both chronobiotic (phase shifting) and soporific effects. In a previous study in our lab, young, healthy, subjects worked five consecutive simulated night shifts (23:00 to 07:00 h) and slept during the day (08:30 to 15:30 h). Large phase delays of various magnitudes were produced by the study interventions, which included bright light exposure during the night shifts, as assessed by the dim light melatonin onset (DLMO) before (baseline) and after (final) the five night shifts. Subjects also ingested either 1.8 mg sustained-release melatonin or placebo before daytime sleep. Although melatonin at this time should delay the circadian clock, this previous study found that it did not increase the magnitude of phase delays. To determine whether melatonin had a soporific effect, we controlled the various magnitudes of phase delay produced by the other study interventions. Melatonin (n=18) and placebo (n=18) groups were formed by matching a melatonin participant with a placebo participant that had a similar baseline and final DLMO (+/-1 h). Sleep log measurements of total sleep time (TST) and actigraphic measurements of sleep latency, TST, and three movement indices for the two groups were examined. Although melatonin was associated with small improvements in sleep quality and quantity, the differences were not statistically significant by analysis of variance. However, binomial analysis indicated that melatonin participants were more likely to sleep better than their placebo counterparts on some days with some measures. It was concluded that, the soporific effect of melatonin is small when administered prior to 7 h daytime sleep periods following night shift work.
