Clinical Care Plan, Interprofessional Course

Evidence suggests interprofessional collaborative practice significantly improves patient outcomes, reduces mortality and enhances quality-of-life.1 Person-focused care demands collaboration among professions in a team approach to address multiple issues including illness, prevention, and health promotion activities. Key elements of successful implementation of interprofessional education are supported in Thomas Jefferson University’s Clinical Care Plan, Interprofessional Course (CCPIC) that includes increasing knowledge of the roles, responsibilities, and competencies of other health professions, collaborating in teams, recognizing the patient as the expert, and communicating effectively

The Effect of Supplemental Medical and Prescription Drug Coverage on Health Care Spending for Medicare Beneficiaries with Cancer

AbstractObjectivesTo examine whether patients with newly diagnosed cancer respond differently to supplemental coverage than the general Medicare population.MethodsA cohort of newly diagnosed cancer patients (n = 1,799) from the 1997-2007 Medicare Current Beneficiary Survey and a noncancer cohort (n = 9,726) were identified and matched by panel year. Two-year total medical care spending was estimated by using generalized linear models with gamma distribution and log link—including endogeneity-corrected models. Interactions between cancer and type of insurance allowed testing for differential effects of a cancer diagnosis.ResultsThe cancer cohort spent an adjusted $15,605 more over 2 years than did the noncancer comparison group. Relative to those without supplemental coverage, beneficiaries with employer-sponsored insurance, other private with prescription drug coverage, and public coverage had significantly higher total spending ($3,510, $2,823, and$4,065, respectively, for main models). For beneficiaries with cancer, supplemental insurance effects were similar in magnitude yet negative, suggesting little net effect of supplemental insurance for cancer patients. The endogeneity-corrected models produced implausibly large main effects of supplemental insurance, but the Cancer × Insurance interactions were similar in both models.ConclusionsMedicare beneficiaries with cancer are less responsive to the presence and type of supplemental insurance than are beneficiaries without cancer. Proposed restrictions on the availability of supplemental insurance intended to reduce Medicare spending would be unlikely to limit expenditures by beneficiaries with cancer, but would shift the financial burden to those beneficiaries. Policymakers should consider welfare effects associated with coverage restrictions

Reduced Sympathetic Innervation Underlies Adjacent Noninfarcted Region Dysfunction During Left Ventricular Remodeling

AbstractObjectives. We examined the association of sympathetic denervation and reduced blood flow with mechanical dysfunction in adjacent noninfarcted regions late after myocardial infarction (MI).Background. Using a well characterized ovine model of left ventricular (LV) remodeling after transmural anteroapical MI, we previously showed that histologically normal adjacent noninfarcted regions demonstrate mechanical dysfunction.Methods. Ten sheep underwent coronary ligation. Magnetic resonance imaging was performed before and 8 weeks after infarction for measurement of LV mass, volumes, ejection fraction and regional intramyocardial circumferential shortening (%S). Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and fluorescent microspheres before and after administration of adenosine were infused before death for measurement of sympathetic innervation, blood flow and blood flow reserve from matched postmortem regions.Results. From baseline to 8 weeks after infarction, LV end-diastolic volume increased from (mean ± SD) 1.5 ± 0.3 to 2.6 ± 0.5 ml/kg (p < 0.001), and LV mass increased from 2.0 ± 0.3 to 2.6 ± 0.5 g/kg (p = 0.001). Regionally, the decline in subendocardial %S was greater in adjacent (19 ± 5% to 8 ± 5%) than in remote noninfarcted regions (20 ± 6% to 19 ± 6%, p < 0.002). No difference in regional blood flow or blood flow reserve was found between adjacent and remote regions, whereas I-123 MIBG uptake was lower in adjacent than in remote myocardium (1.09 ± 0.30 vs. 1.31 ± 0.40 nmol/g, p < 0.003). Topographically, from apex to base at 8 weeks after infarction, %S correlated closely with I-123 MIBG uptake (r = 0.93, p = 0.003).Conclusions. In mechanically dysfunctional noninfarcted regions adjacent to chronic transmural myocardial infarction in the remodeled left ventricle, blood flow and blood flow reserve are preserved, yet sympathetic innervation is reduced. Chronic sympathetic denervation in adjacent noninfarcted regions, in association with regional mechanical dysfunction, may contribute to LV remodeling after infarction

Community and service provider views to inform the 2013 WHO consolidated antiretroviral guidelines:key findings and lessons learnt

Objective:The objective was to evaluate community and healthcare worker (HCW) values and preferences on key topics to inform the development of the 2013 WHO consolidated guidelines for antiretroviral therapy in low and middle income countries. Design:Cross-sectional e-survey and e-forum discussion; focus group discussions (FGDs) Methods:Data were collected on community perspectives regarding a range of potential clinical and operational recommendations in the 2013 guidelines between November 2012 and January 2013 through an e-survey (n = 1088) and e-forum (n = 955). Additional FGDs were held with people living with HIV (PLHIV) in Malawi and Uganda (n = 88) on antiretroviral therapy (ART) use among pregnant women. Two surveys were also undertaken on similar topics covered in the e-survey for health care workers caring for adults (n = 98) and children (n = 348). Results:There were 1088 e-survey respondents from 117 countries: of whom 37.7% (298/791) were females, 49.9% (431/864) PLHIV, and 20.9% (174/831) from low-income countries. The proportion of e-survey respondents who supported raising the CD4 T-cell threshold for ART initiation in adults from 350 to 500 cells/μl was 51.0% (355/696), and regardless of CD4 T-cell count for all pregnant females 89.8% (607/676), HIV serodiscordant partners 71.9% (486/676), and all children on diagnosis of infection 47.4% (212/447). E-survey respondents strongly supported discontinuing use of stavudine (72.7%, 416/572), task-shifting/sharing from doctors to nurses (75.2%, 275/365) and from nurses to community health workers (71.1%, 261/367) as strategies to expand access to HIV testing, care, and treatment. Focus group discussion respondents identified service capacity, and social and legal concerns as key considerations influencing the decisions of women living with HIV to continue ART after the risk of vertical transmission has passed. Key lessons learnt in these consultations included the need for piloting and validation of questions; sufficient time to adequately disseminate the survey; and consideration of using FGDs and mobile phone technology to improve participation of people with limited internet access. Conclusion:Community participation in guideline development processes is important to ensure that their perspectives are considered in the resulting recommendations. Communities should be actively involved in the adaptation, implementation, and accountability processes related to the guidelines

Maximizing the impact of HIV prevention efforts: Interventions for couples

Despite efforts to increase access to HIV testing and counseling services, population coverage remains low. As a result, many people in sub-Saharan Africa do not know their own HIV status or the status of their sex partner(s). Recent evidence, however, indicates that as many as half of HIV-positive individuals in ongoing sexual relationships have an HIV-negative partner and that a significant proportion of new HIV infections in generalized epidemics occur within serodiscordant couples. Integrating couples HIV testing and counseling (CHTC) into routine clinic- and community-based services can significantly increase the number of couples where the status of both partners is known. Offering couples a set of evidence-based interventions once their HIV status has been determined can significantly reduce HIV incidence within couples and if implemented with sufficient scale and coverage, potentially reduce population-level HIV incidence as well. This article describes these interventions and their potential benefits

Optimizing management of invasions in an uncertain world using dynamic spatial models

Dispersal drives invasion dynamics of nonnative species and pathogens. Applying knowledge of dispersal to optimize the management of invasions can mean the difference between a failed and a successful control program and dramatically improve the return on investment of control efforts. A common approach to identifying optimal management solutions for invasions is to optimize dynamic spatial models that incorporate dispersal. Optimizing these spatial models can be very challenging because the interaction of time, space, and uncertainty rapidly amplifies the number of dimensions being considered. Addressing such problems requires advances in and the integration of techniques from multiple fields, including ecology, decision analysis, bioeconomics, natural resource management, and optimization. By synthesizing recent advances from these diverse fields, we provide a workflow for applying ecological theory to advance optimal management science and highlight priorities for optimizing the control of invasions. One of the striking gaps we identify is the extremely limited consideration of dispersal uncertainty in optimal management frameworks, even though dispersal estimates are highly uncertain and greatly influence invasion outcomes. In addition, optimization frameworks rarely consider multiple types of uncertainty (we describe five major types) and their interrelationships. Thus, feedbacks from management or other sources that could magnify uncertainty in dispersal are rarely considered. Incorporating uncertainty is crucial for improving transparency in decision risks and identifying optimal management strategies. We discuss gaps and solutions to the challenges of optimization using dynamic spatial models to increase the practical application of these important tools and improve the consistency and robustness of management recommendations for invasions

Differential Pulmonary Effects of CoO and La2O3 Metal Oxide Nanoparticle Responses During Aerosolized Inhalation in Mice

Background: Although classified as metal oxides, cobalt monoxide (CoO) and lanthanum oxide (La2O3) nanoparticles, as representative transition and rare earth oxides, exhibit distinct material properties that may result in different hazardous potential in the lung. The current study was undertaken to compare the pulmonary effects of aerosolized whole body inhalation of these nanoparticles in mice. Results: Mice were exposed to filtered air (control) and 10 or 30 mg/m3 of each particle type for 4 days and then examined at 1 h, 1, 7 and 56 days post-exposure. The whole lung burden 1 h after the 4 day inhalation of CoO nanoparticles was 25 % of that for La2O3 nanoparticles. At 56 days post exposure, \u3c 1 % of CoO nanoparticles remained in the lungs; however, 22–50 % of the La2O3 nanoparticles lung burden 1 h post exposure was retained at 56 days post exposure for low and high exposures. Significant accumulation of La2O3 nanoparticles in the tracheobronchial lymph nodes was noted at 56 days post exposure. When exposed to phagolysosomal simulated fluid, La nanoparticles formed urchin-shaped LaPO4 structures, suggesting that retention of this rare earth oxide nanoparticle may be due to complexation of cellular phosphates within lysosomes. CoO nanoparticles caused greater lactate dehydrogenase release in the bronchoalveolar fluid (BALF) compared to La2O3 nanoparticles at 1 day post exposure, while BAL cell differentials indicate that La2O3 nanoparticles generated more inflammatory cell infiltration at all doses and exposure points. Histopathological analysis showed acute inflammatory changes at 1 day after inhalation of either CoO or La2O3 nanoparticles. Only the 30 mg/m3 La2O3 nanoparticles exposure caused chronic inflammatory changes and minimal fibrosis at day 56 post exposure. This is in agreement with activation of the NRLP3 inflammasome after in vitro exposure of differentiated THP-1 macrophages to La2O3 but not after CoO nanoparticles exposure. Conclusion: Taken together, the inhalation studies confirmed the trend of our previous sub-acute aspiration study, which reported that CoO nanoparticles induced more acute pulmonary toxicity, while La2O3 nanoparticles caused chronic inflammatory changes and minimal fibrosis
