Leading Nursing Excellence Through a System Magnet® Program Director Council.

American Nurses Credentialing Center Magnet® designation is prestigious to healthcare institutions. Setting the expectation for all hospitals within a system to be Magnet designated is a lofty but achievable goal. Nursing leaders at the University of Pittsburgh Medical Center set organization-wide designation as a goal in 2010. A robust system-wide Magnet Program Directors Council facilitated this effort by standardizing practices and supporting members through the journey.

"A Judgment-Free Zone": Adaptation and Pilot Study of a Virtual Wellness Group for African American Mothers with Young Children.

The COVID-19 pandemic has been particularly challenging for the mental health of African American (AA) birthing people. The pandemic necessitated shifting mental health care to online interventions. The goals of this study were to (1) describe an adapted evidence-based group preventive intervention for AA mothers with young children within a pediatric setting and (2) evaluate the feasibility, acceptability, and preliminary effectiveness of this virtual intervention. Phase 1 describes the adaptation of the HealthySteps Mom's Virtual Wellness Group, including eight weekly sessions based on the Mothers and Babies Course. Phase 2 was a mixed-methods, pre-post intervention design. Six AA mothers with young children completed questionnaires related to depression, anxiety, and parenting competence at three time points: pre-intervention (T1), post-intervention (T2), and 3 months post-intervention (T3). The participants also completed a focus group post-T2 to gather qualitative feedback regarding the intervention. The median scores for depression were lower at T2 and increased at T3, and for anxiety, they increased at T2 and decreased at T3. The median scores for parenting competence increased across the three time points. The participants attended a mean of 7.2 sessions (SD = 0.74). The qualitative results indicate that the participants gained a sense of empowerment, enjoyed connecting with other mothers, and acquired information. This pilot study suggests that a virtual intervention is feasible, acceptable, and can increase parenting competence and support among AA mothers with young children.

Patient expectations from implantable defibrillators to prevent death in heart failure.

BACKGROUND: Indications for implantable cardioverter-defibrillators (ICDs) in heart failure (HF) are expanding and may include more than 1 million patients. This study examined patient expectations from ICDs for primary prevention of sudden death in HF. METHODS AND RESULTS: Study participants (n = 105) had an EF <35% and symptomatic HF, without history of ventricular tachycardia/fibrillation or syncope. Subjects completed a written survey about perceived ICD benefits, survival expectations, and circumstances under which they might deactivate defibrillation. Mean age was 58, LVEF 21%, 40% were New York Heart Association Class III-IV, and 65% already had a primary prevention ICD. Most patients anticipated more than10 years survival despite symptomatic HF. Nearly 54% expected an ICD to save >or=50 lives per 100 during 5 years. ICD recipients expressed more confidence that the device would save their own lives compared with those without an ICD (P < .001). Despite understanding the ease of deactivation, 70% of ICD recipients indicated they would keep the ICD on even if dying of cancer, 55% even if having daily shocks, and none would inactivate defibrillation even if suffering constant dyspnea at rest. CONCLUSIONS: HF patients anticipate long survival, overestimate survival benefits conferred by ICDs, and express reluctance to deactivate their devices even for end-stage disease.

The antitumor activity of an anti-CD54 antibody in SCID mice xenografted with human breast, prostate, non-small cell lung, and pancreatic tumor cell lines.

We have previously described the development and testing of a monoclonal anti-human CD54 antibody (UV3) in SCID mice xenografted with human multiple myeloma, lymphoma, and melanoma cell lines. In all 3 cases, UV3 was highly effective at slowing the growth of tumors and/or prolonging survival. Since CD54 (ICAM-1) is up-regulated on many different types of cancer cells, we have now investigated the anti-tumor activity of UV3 in several other CD54(+) epithelial tumors. A panel of 16 human breast, prostate, non-small cell (NSC) lung, and pancreatic tumor cell lines was examined for reactivity with UV3, and 13 were positive. A representative CD54(+) cell line from each cancer was grown subcutaneously in SCID mice. Once the tumors were established, UV3 was administered using different dose regimens. UV3 slowed the growth of all 4 tumors, although it was not curative. When UV3 or gemcitabine were administered to SCID mice xenografted with a NSC lung tumor cell line or a pancreatic tumor cell line, UV3 was as effective as the chemotherapy alone. When gemcitabine and UV3 were administered together, the best anti-tumor responses were observed. UV3 has been chimerized (cUV3) and both toxicology studies and clinical trials are planned to assess the safety and activity of cUV3 in patients with one or more of these tumors.

Thresholds of physical activity and life expectancy for patients considering destination ventricular assist devices.

BACKGROUND: Current implantable left ventricular assist devices (LVAD) improve survival and function for patients with very late stage heart failure (HF) but may also offer benefit before inotrope dependence. Debate continues about selection of HF patients for LVAD therapy. We sought to determine what level of personal risk and disability HF patients thought would warrant LVAD therapy. METHODS: The study included 105 patients with symptomatic HF and an LV ejection fraction (EF) < 35% who were given a written paragraph about LVADs and asked about circumstances under which they would consider such a device. New York Heart Association (NYHA) functional class, time trade-off utility, and patient-assessed functional score were determined. RESULTS: Participants (mean age, 58 years) had an LVEF of 21%. The median duration of HF was 5 years, and 65% had a primary prevention implantable cardioverter defibrillator. Presented with a scenario of bed-ridden HF, 81% stated they would definitely or probably want an LVAD; 50% would consider LVAD to prolong survival if HF survival were predicted to be < 1 year and 75% if < 6 months. Meanwhile, 44% would consider LVAD if they could only walk < 1 block and 64% if they could not dress without stopping. Anticipated thresholds did not differ by NYHA class, time trade-off, or functional score. CONCLUSIONS: Patient thresholds for LVAD insertion parallel objective survival and functional data. HF patients would be receptive to referral for discussion of LVAD by the time expected mortality is within 6 to 12 months and activity remains limited to less than 1 block.

The Fc portion of UV3, an anti-CD54 monoclonal antibody, is critical for its antitumor activity in SCID mice with human multiple myeloma or lymphoma cell lines.

UV3 is a monoclonal antibody that recognizes human CD54 (intercellular adhesion molecule-1), and it was generated for the therapy of human multiple myeloma. In a severe combined immunodeficient (SCID) xenograft model of human multiple myeloma, UV3 significantly prolonged the survival of mice with either early or advanced stages of disease. However, the mechanism by which UV3 exerted its antitumor effect remained unknown. As reported previously UV3 could mediate antibody-dependent cell-mediated cytotoxicity or complement-dependent cytotoxicity in vitro. F(ab)'2 fragments of UV3 had therapeutic efficacy in vivo, suggesting that effector functions were not critical. The purpose of this study was to further define the importance of the Fc portion of UV3 for its antitumor activity in vivo. To this end, we examined the effect of an "ultrapure" preparation of UV3 F(ab)'2 to treat SCID mice xenografted with either ARH-77 cells, a human multiple myeloma cell line, or Daudi cells, a human Burkitt's lymphoma cell line. In addition, we evaluated different doses of UV3 immunoglobulin G (IgG) in these mice to determine the minimum amount of IgG that would produce a therapeutic effect. Data obtained from this study suggest that (1) the Fc portion of UV3 is critical for its antitumor activity in vivo, (2) low levels of UV3 IgG in a preparation of F(ab)'2 fragments account for all of its in vivo activity in multiple myeloma and most of its activity in lymphoma, and (3) UV3 IgG significantly prolongs the survival of SCID/ARH-77 mice as well as SCID/Daudi mice.

Effect of an anti-CD54 (ICAM-1) monoclonal antibody (UV3) on the growth of human uveal melanoma cells transplanted heterotopically and orthotopically in SCID mice.

We have shown that administration of a novel anti-CD54 monoclonal antibody (UV3) results in long-term survival of SCID mice bearing human myeloma xenografts. Previous studies have demonstrated a link between the expression of CD54 and the progression of uveal melanoma. Our study assessed the expression of CD54 on 7 human uveal melanoma cell lines and 3 cell lines established from uveal melanoma metastases. In vivo studies examined the efficacy of systemic and local administration of UV3 antibody on the progression of uveal melanoma cells transplanted either heterotopically or orthotopically into SCID mice. Five of the 7 primary uveal melanoma cell lines and all 3 of the metastases cell lines expressed CD54. Intraperitoneal injection of either IgG or F(ab')2 fragments of UV3 significantly inhibited the growth of subcutaneous and intraocular melanomas. Subconjunctival injection of either IgG or F(ab')2 fragments of UV3 produced a significant reduction in the growth of intraocular melanomas, even if the antibody was administered after the appearance of intraocular tumors. The results indicate that both primary and metastatic human uveal melanoma cells express CD54. The marked inhibition of intraocular and subcutaneous uveal melanoma progression suggests that UV3 antibody is a promising therapeutic agent for further evaluation in patients with uveal melanoma. This is especially noteworthy, as no existing therapeutic modality prevents metastasis of uveal melanoma or prolongs the survival of patients with uveal melanoma.
