The Development of a Video-based Nutrition Education Curriculum for Patients Undergoing Radical Cystectomy.

BACKGROUND: The treatment for patients with muscle-invasive bladder cancer includes neoadjuvant chemotherapy followed by radical cystectomy. The American Urological Association guidelines stress the optimization of patient performance status in the perioperative setting. Therefore, implementation of nutrition education is critical for the multi-disciplinary care of this vulnerable patient population and wide distribution of information is critical. OBJECTIVE: The goal of our study was to create a nutrition-based video education series for patients undergoing chemotherapy and radical cystectomy for bladder cancer. METHODS: Scripts for the videos were developed through an iterative process by experts in nutrition, urology, and communication. Providers and patient advocates were recruited to perform semi-structured interviews and surveys for additional feedback. Performer facial emotion recognition (Noldus™) was used to assess displayed emotion by the presenters. Mangold VisionPlayer software was used for participant eye movement tracking of the video content. A knowledge survey was created, and Item Content Validity Index (I-CVI) was calculated with a nutrition expert advisory board. Participants were recruited for cognitive interviewing to understand the mental processes and interpretations while answering questions. RESULTS: The video series is available to the public on the Bladder Cancer Advocate Network (BCAN) website at the following URL: https://bcan.org/facing-bladder-cancer/nutrition-bladder-cancer/eating-healthy-bladder-cancer/. Cinematic filming methods, (smaller depth of field, lighting, and camera movement) enhanced message delivery along with music and text on screen to anchor important concepts. CONCLUSIONS: This study can be a framework for the development of a patient education video library accessible through electronic medical records, health care applications, and patient advocacy websites.

Echocardiographic Assessment of Melody Versus Sapien Valves Following Transcatheter Pulmonary Valve Replacement.

OBJECTIVES: The aim of this study was to compare the immediate and midterm echocardiographic performance of the Melody (Medtronic Inc) and Sapien (Edwards Lifesciences Inc) valves after transcatheter pulmonary valve replacement (TPVR) in native and conduit right ventricular outflow tracts (RVOTs). BACKGROUND: TPVR is now a common procedure, but limited data exist comparing postimplantation echocardiographic findings between Melody and Sapien valves. METHODS: This was a single-institution retrospective cohort study of all patients who underwent successful TPVR from 2011 to 2020. Patient demographics, procedural details, and immediate and midterm echocardiographic findings were collected and compared between valve types using the Wilcoxon rank sum, chi-square, or Fisher exact test as appropriate. Subgroups were analyzed individually and were adjusted for multiple comparisons using the Bonferroni method. RESULTS: A total of 328 patients underwent successful TPVR (Melody: n = 202, Sapien: n = 126). The groups had a similar baseline age, weight, and diagnosis. The most common indications for TPVR were pulmonary stenosis (32.2%) or mixed disease (46%) in the Melody group and pulmonary insufficiency in the Sapien group (52.4%) (P < 0.001). Sapien valves were more often placed in native RVOTs (43.7% vs 18.8%; P < 0.001). The discharge and follow-up mean and peak Doppler gradients were similar between the Melody and Sapien groups. Valves implanted in native RVOTs had significantly lower postimplantation gradients at each follow-up period. CONCLUSIONS: Echocardiographic performance after TPVR was generally acceptable and similar when comparing Melody and Sapien valves despite differences in the indication and anatomy in each group. The peak and mean gradients were lower in transcatheter valves implanted in native RVOTs compared with those implanted in conduits or bioprosthetic valves.

Percutaneous transcatheter pulmonary valve replacement in children weighing less than 20 kg.

BACKGROUND: Since FDA approval of the Melody valve, transcatheter pulmonary valve replacement (TPVR) has been offered to an expanding population. Limited data exist regarding the safety and feasibility of TPVR in smaller patients. METHODS: All patients weighing <20 kg who underwent catheterization for percutaneous TPVR at four centers were reviewed. RESULTS: Of the 51 patients reviewed, 43 (84%) had successful valve implantation and 8 (16%) were found not to be candidates due to access veins too small (n = 3), coronary artery/aortic root compression (n = 3), and RVOT too large (n = 2). The 43 patients who underwent successful percutaneous TPVR had a median age and weight of 5.8 years (3.3-10) and 17.7 kg (13.5-19.8), and most had tetralogy of Fallot (TOF). TPVR was performed via femoral vein (FV) access in 24 patients and internal jugular vein (IJV) access in 19 patients. Median weight in patients with IJV implant was 1.1 kg lower than those who underwent transfemoral implant (17.0 vs. 18.1 kg, P = 0.05). There were four adverse events: one iliac vein injury, one contained MPA tear, and two patients with post-procedure femoral vein bleeding. All patients were alive at recent follow-up, a median of 2.0 years (0.1-6.0) after TPVR. There was excellent valve function with mean Doppler gradients of 3-20 mm Hg, and trivial or mild pulmonary regurgitation in all but one patient. There were no RVOT reinterventions and no cases of endocarditis. CONCLUSIONS: Percutaneous TPVR can be safely performed in patients <20 kg. The procedure frequently requires IJV access, and access site/bleeding complications may be more common in this cohort.

The relationship between adult health and childhood maltreatment, as moderated by anger and ethnic background.

Childhood maltreatment, anger, and racial/ethnic background were examined in relation to physical health, psychological well-being, and blood pressure outcomes. This study used data from a diverse sample of African American, Latino, and Caucasian participants (N=198). Results from a series of multiple regressions indicated anger and total childhood maltreatment were robust predictors of poorer health. Although correlational analyses found maltreatment from the mother and father were associated with poorer health outcomes, when considered as part of the regression models, only a relationship between maltreatment from the mother and physical health was found. Greater anger scores were linked with lower blood pressure, particularly systolic blood pressure. Generally, more psychological and physical symptom reporting was found with greater anger scores, and higher levels of total maltreatment also predicted physical symptoms. The pattern of interactions indicated anger was more detrimental for African American participant's (and marginally so for Latino participant's) physical health. Interestingly, interactions also indicated total childhood maltreatment was related to fewer symptoms for Latino participants. Although child maltreatment may be viewed as a moral and/or human rights issue, this study provides evidence that it can also be viewed as a public health issue. Our study demonstrated that known health risk factors such as anger and maltreatment may operate in a different pattern dependent on ethnic/cultural background. The findings suggest health and health disparities research would benefit from greater exploration of the differential impact of certain moderating variables based on racial/ethnic background.

Incorporating wellness into employee benefit strategies--why it makes sense.

By putting together a comprehensive wellness strategy, employers are not only "doing the right thing" but also are able to see, believe and maintain the tangible return on investment (ROI) that wellness programs are capable of delivering. This article discusses employers' ROI from wellness initiatives, as well as innovations that support a culture of wellness and what enhanced opportunities for increasing employee wellness are available under health care reform. It also describes how wellness is a component of population health management, as well as a core component of the health care delivery system.

Food expenditures and food purchasing among low-income, urban, African-American youth.

BACKGROUND: Low-income, urban African-American youth are at higher risk for obesity and less likely to meet dietary recommendations than white, higher-income youth. Patterns of food purchasing among youth likely contribute to these disparities, but little published information is available. PURPOSE: To investigate food purchasing behaviors of low-income, urban African-American youth. METHODS: A total of 242 African-American youth, aged 10-14 years, were recruited from 14 recreation centers in low-income, predominantly African-American neighborhoods in Baltimore MD. Youth reported the amount of money typically spent on food, the source of this money, the place of purchase, and frequency of purchase for 29 foods and beverages. Data were collected in 2008-2009 and analyzed in 2009-2010. RESULTS: Youth reported spending an average of $3.96 on foods and beverages in a typical day. Corner stores were the most frequently visited food source (youth made purchases at these stores an average of 2.0 times per week). Chips, candy, and soda were the most commonly purchased items, with youth purchasing these an average of 2.5, 1.8, and 1.4 times per week, respectively. Older age was associated with more money spent on food in a typical day (p<0.01). CONCLUSIONS: Food purchasing among low-income, urban African-American youth is frequent and substantial. Interventions aimed at preventing and treating obesity in this population should focus on increasing access to healthy foods in their neighborhoods, especially in corner stores.

Changing mechanisms of opiate tolerance and withdrawal during early development: animal models of the human experience.

Human infants may be exposed to opiates through placental transfer from an opiate-using mother or through the direct administration of such drugs to relieve pain (e.g., due to illness or neonatal surgery). Infants of many species show physical dependence and tolerance to opiates. The magnitude of tolerance and the nature of withdrawal differ from those of the adult. Moreover, the mechanisms that contribute to the chronic effects of opiates are not well understood in the infant but include biological processes that are both common to and distinct from those of the adult. We review the animal research literature on the effects of chronic and acute opiate exposure in infants and identify mechanisms of withdrawal and tolerance that are similar to and different from those understood in adults. These mechanisms include opioid pharmacology, underlying neural substrates, and the involvement of other neurotransmitter systems. It appears that brain circuitry and opioid receptor types are similar but that NMDA receptor function is immature in the infant. Intracellular signaling cascades may differ but data are complicated by differences between the effects of chronic versus acute morphine treatment. Given the limited treatment options for the dependent infant patient, further study of the biological functions that are altered by chronic opiate treatment is necessary to guide evidenced-based treatment modalities.

NCLEX fairness and sensitivity review.

The National Council Licensing Examination is an examination that is used for the purpose of licensing registered nurses and practical/vocational nurses. To help ensure that the examination questions (items) are fair and unbiased, all items undergo a fairness and sensitivity review as part of the item development process. This article focuses on the fairness and sensitivity review.

Phase I/II trial of hyperfractionated radiation and chemotherapy followed by surgery in stage III lung cancer.

BACKGROUND: We have previously demonstrated that high-dose chemoradiotherapy followed by resection for patients selected on the basis of mediastinal sterilization was feasible and resulted in excellent outcomes. This study was designed to determine the ability to intensify our prior approach utilizing hyperfractionated radiation and more aggressive consolidative chemotherapy. METHODS: Patients with documented stage IIIA/B nonsmall-cell lung cancer, performance status 0 to 2, and adequate organ function were eligible. A phase I portion utilized escalating doses of carboplatin and vinorelbine, commencing with areas under the curve of 1 and 5 mg/m(2), respectively, and concurrent 69.6 Gy hyperfractionated radiotherapy. A phase II portion utilized the identical radiotherapy with carboplatin/vinorelbine at the maximum tolerated dose established in phase I. Patients for whom mediastinal nodal clearance was demonstrated underwent resection. All patients were to receive consolidation chemotherapy consisting of carboplatin/vinorelbine for three cycles, followed by docetaxel for three cycles. Prophylactic cranial irradiation was offered to patients after completion of therapy. RESULTS: Forty-seven patients participated in the study (33 IIIA, 14 IIIB; 15 men, 32 women; median age, 56 years). The maximum tolerated dose for concurrent carboplatin/vinorelbine and hyperfractionated radiotherapy was established at areas under the curve of 1 and 10 mg/m(2), respectively. Twenty-eight patients completed trimodality treatment including surgery. Median survival time for the entire study cohort (n = 47) is 29.6 months, and it is 55.8 months for patients with mediastinal clearance who underwent resection (n = 28). CONCLUSIONS: Surgical resection of locally advanced stage IIIA and IIIB nonsmall-cell lung cancer after induction hyperfractionated radiation and concurrent chemotherapy is safe and well tolerated. Whether this approach is superior to less aggressive therapy is uncertain and will require comparative studies.

Mid- to late gestational morphine exposure does not alter the rewarding properties of morphine in adult male rats.

Prenatal exposure to drugs of abuse often leads to physiological and neurobiological abnormalities including decreased brain and body weight, cognitive deficits and behavioral alterations. A handful of studies showed increased vulnerability to drug abuse in prenatally drug-exposed offspring. Our work also demonstrated that prenatal exposure to analgesic doses of morphine during gestation days 11-18 increases mu-opioid receptor density in the nucleus accumbens and central amygdala of adult male rats. Both the nucleus accumbens and central amygdala play important roles in modulating drug-induced reward via the mesolimbic dopaminergic system. Therefore, two types of behavioral paradigms were used to test the hypothesis that the same prenatal morphine exposure would enhance the rewarding effects of morphine, making drug-exposed offspring more vulnerable to abuse this drug in adulthood. All experiments were performed with adult male offspring of saline-injected, morphine-injected or non-injected (control) dams. (1) The unbiased conditioned place preference (CPP) paradigm was used to investigate whether prenatal morphine exposure sensitizes adult male rats to non-contingent morphine reward. These adult animals were conditioned with 0.1, 0.3, 1, 3 or 5 mg/kg morphine. All control, prenatally saline- and morphine-exposed male rats preferred the morphine-paired compartment relative to the saline-paired compartment. However, the magnitude of morphine CPP in adult male rats was not dependent on the conditioning dose of morphine or prenatal morphine exposure. (2) Intravenous morphine self-administration was used to assess the behavioral response to contingent morphine reward. Each rat self-administered one of four doses of morphine (0.3, 1, 2 or 3 mg/kg/infusion). Morphine self-administration was not altered in prenatally morphine-exposed adult male offspring. Control males self-administered significantly less morphine at the lowest dose of morphine than both prenatally saline- and morphine-exposed males. Although our data show that prenatal exposure to an analgesic dose of morphine during the time of opioid receptor appearance does not enhance morphine CPP or self-administration, they do not exclude the possibility that this prenatal morphine exposure enhances the rewarding properties of other drugs of abuse.
