Abstract

Background: Patients with diffuse pulmonary arteriovenous malformations (PAVM), a small but important subset of the PAVM population, have significant morbidity and mortality rates. Methods: Thirty-six patients (21 female and 15 male) with diffuse PAVM from a cohort of 821 consecutive patients with PAVM were evaluated. Diffuse PAVM were categorized angiographically: involvement of one or more segmental pulmonary arteries in one or both lungs. Hereditary hemorrhagic telangiectasia (HHT) status, gender, presence or absence of large (≥ 3-mm diameter artery) focal PAVM, oxygen saturations, complications including hemoptysis, years of follow-up, and survival were tabulated. Results: HHT was present in 29 of 36 patients (81%), and diffuse PAVM were more commonly bilateral (26 of 36 patients, 72%) than unilateral (10 of 36 patients, 28%) [p = 0.02]. Female gender was associated with bilateral diffuse PAVM (19 of 26 patients, 73%) [p = 0.01]. Focal PAVM were present in both groups but more commonly in patients with bilateral involvement (16 of 26 patients, 62%) [p = 0.02]. Initial oxygen saturations (pulse oximetry, standing) of patients with unilateral and bilateral diffuse PAVM were 87 ± 7% and 79 ± 8% (mean ± SD), respectively (p = 0.02). The last or current values for patients with unilateral and bilateral involvement are 95 ± 3% and 85 ± 7%, respectively (p < 0.0001). Nine deaths occurred, and all were in patients with bilateral involvement. Deaths were due to hemoptysis of bronchial artery origin (n = 2), hemorrhage from duodenal ulcer (n = 1), spontaneous liver necrosis (n = 3), brain hemorrhage (n = 1), brain abscess (n = 1), and operative death during attempted lung transplant (n = 1). Conclusions: Patients with diffuse PAVM are a high-risk group, and yearly follow-up is recommended.

Whether it's already touching your facility or its impact is still to come, this crisis will test your skills as a manager. Understanding what's driving the shortage and what's predicted will help you choose the best strategies for addressing its causes and dealing with its consequences.

Abstract

Countries across the globe are experiencing nursing shortages. In hospitals, supportive practice environments have positive effects on both nurse and patient outcomes. However, these relationships have been established primarily in the US. International studies of the effects of nurse staffing levels and the practice environment on nurse outcomes and the quality of care mirror the findings from the US, thus raising these issues to the international level. The solutions that have been successful in the US for improving the practice environment and patient outcomes are solutions that should be successful in any country, thus putting them on a global scale. The Magnet hospital program is one model that has been shown to improve nurse and patient outcomes and is one solution to the shortage of hospital nurses.

Abstract

This article reports the results of a study carried out with 30 Mexican-origin immigrants in drug user treatment in the United States-Mexico Border city of El Paso, Texas during 2007. Qualitative, semi-structured interviews were implemented to assess the dynamic social and economic factors that affect the delivery and utilization of treatment services, with emphasis on the impact of recent immigration-related laws and policies. The research provides initial data for evidence-based intervention and reinforces the need for culturally and gender appropriate treatment services for poor immigrants and their families. The study's limitations are noted.

Abstract

Purpose: In a sample of family caregivers (FCs) of patients with prostate cancer who were to begin radiation therapy (RT), the purposes were to determine the prevalence and severity of depression, anxiety, pain, sleep disturbance, and fatigue; determine the relationships among these symptoms and between these symptoms and functional status and quality of life (QOL); evaluate for differences in functional status and QOL between FCs with low and high levels of these symptoms; and determine which factors predicted FCs' functional status and QOL. Patients and Methods: FCs were recruited before patients initiated RT and completed self-report questionnaires that evaluated demographic characteristics, symptoms, functional status, and QOL. Results: Sixty female FCs participated in the study. On the basis of established cut point scores for each symptom questionnaire, 12.2% of the FCs had clinically meaningful levels of depression, 40.7% anxiety, 15.0% pain, 36.7% sleep disturbance, 33.3% morning fatigue, and 30.0% evening fatigue. FCs who were older and who had lower levels of state anxiety and higher levels of depression, morning fatigue, and pain reported significantly poorer functional status (R2 = 38.7%). FCs who were younger, had more years of education, were working, and who had higher levels of depression, morning fatigue, sleep disturbance, and lower levels of evening fatigue reported significantly lower QOL scores (R2 = 70.1%). Conclusion: A high percentage of FCs experienced clinically meaningful levels of a variety of symptoms. These symptoms have a negative impact on the FCs' functional status and QOL.

Abstract

Objectives: Difficulties with diagnosis and aggressive, long-term treatment may result in lower quality of life (QOL), including high levels of anxiety, depression, and uncertainty, greater symptom distress, and lower overall QOL among women with avarian cancer. The purpose of this study was to describe demographic, clinical, and other risk factors associated with compromised QOL among women who have undergone surgery for avarian malignancies. Methods: Subjects were recruited to participate in a clinical trial that tested a specialized nursing intervention addressing psychological and physical care among women post-surgical for avarian cancer. QOL was measured using five standardized self-report measures: the State-Trait Anxiety Scale (SAS), the Center for Epidemiological Studies Depression Scale (CES-D), the Mishel Uncertainty in Illness Scale (MUIS), the Symptom Distress Scale (SDS), and the Short-Form Health Survey (SF-12). Baseline data were collected while women were hospitalized following surgery. Results: The sample (n=145) included women with avarian cancer (58%) and other cancers metastasized to the avaries and abdomen (42%). Mean scores on the measures were consistent with or higher than previously reported means for similar populations. Women reporting the lowest QOL were more likely to be younger, more educated, and have early stage disease. Significance of results: Women who have undergone surgery for ovarian malignancies have psychological needs that are often considered secondary to physical needs. Interventions should include routine screening for distress and referral to appropriate psychological and social services, thereby facilitating quality cancer care.

Abstract

Objectives. To explore the association between implicit rationing of nursing care and selected patient outcomes in Swiss hospitals, adjusting for major organizational variables, including the quality of the nurse practice environment and the level of nurse staffing. Rationing was measured using the newly developed Basel Extent of Rationing of Nursing Care (BERNCA) instrument. Additional data were collected using an adapted version of the International Hospital Outcomes Study questionnaire. Design. Multi-hospital cross-sectional surveys of patients and nurses. Setting. Eight Swiss acute care hospitals Participants. Nurses (1338) and patients (779) on 118 medical, surgical and gynecological units. Main outcome measures. Patient satisfaction, nurse-reported medication errors, patient falls, nosocomial infections, pressure ulcers and critical incidents involving patients over the previous year. Results. Generally, nurses reported rarely having omitted any of the 20 nursing tasks listed in the BERNCA over their last 7 working days. However, despite relatively low levels, implicit rationing of nursing care was a significant predictor of all six patient outcomes studied. Although the adequacy of nursing resources was a significant predictor for most of the patient outcomes in unadjusted models, it was not an independent predictor in the adjusted models. Low nursing resource adequacy ratings were a significant predictor for five of the six patient outcomes in the unadjusted models, but not in the adjusted ones. Conclusion. As a system factor in acute general hospitals, implicit rationing of nursing care is an important new predictor of patient outcomes and merits further study.

Abstract

Little attention has been given to the effects of registered nurse (RN) staffing and processes of nursing care on patient outcomes in hemodialysis units. This research examined the effects of patient-to-RN ratios and necessary tasks left undone by RNs on the likelihood of nurse-reported frequent occurrences of adverse patient events in chronic hemodialysis units. Study findings revealed that high patient-to-RN ratios and increased numbers of tasks left undone by RNs were associated with an increased likelihood of frequent occurrences of dialysis hypotension, skipped dialysis treatments, shortened dialysis treatments, and patient complaints in hemodialysis units. These findings indicate that federal, state, and dialysis organization policies must foster staffing structures and processes of care in dialysis units that effectively utilize the invaluable skills and services of professional, registered nurses.

Abstract

▶ Background: Although religion and spirituality are prominent in the lives of Black women with type 2 diabetes (T2DM), there is little research on the relationships of religion and spirituality to glycemic control (GC) in this population. ▶ Objective: To examine the relations of religion and spirituality to GC. ▶ Methods: Using a cross-sectional, descriptive, correlational design, a convenience sample of 109 Black women with T2DM was recruited. Measures of demographic (age, income, and education), clinical (body mass index and use of diabetes medications), psychosocial (emotional distress and social support), religion and spirituality (religious and existential well-being), and GC (hemoglobin A1c) factors were collected. A theoretical model, based on the work of Koenig, McCullough, and Larson (2001), informed linear regression analyses to examine the relations of religion and spirituality to GC, with psychosocial factors as putative mediators. ▶ Results: With age (β = -.133, SE = .020, p = .145), income (β =.020, SE = .139, p = .853), education (β = -.221, SE = .204, p = .040), body mass index (β= - .237, SE = .031, p = .011), and diabetes medications (β = .338, SE = .216, p < .001) held constant, religion and spirituality demonstrated significant relations with GC (β = .289, SE = .032, p = .028 and β = -.358, SE = .030, p = .006, respectively). Evidence of emotional distress and social support as mediators in the relationships of religion and spirituality to GC was lacking. ▶ Discussion: Religion and spirituality were related to GC, with evidence of psychosocial mediation lacking, thereby forcing revision of the model for the study population. Research is warranted to validate the findings, with further examination of theoretical mediators linking religion and spirituality to GC. Findings suggest that religion and spirituality be addressed in diabetes care to improve GC in Black women with T2DM.

Abstract

Aims: Recent large association studies have revealed associations between genetic polymorphisms and myocardial infarction and coronary heart disease (CHD). We performed a replication study of 10 polymorphisms and CHD in a population with familial hypercholesterolemia (FH), individuals at extreme risk of CHD. Methods and results: We genotyped 10 polymorphisms in 2145 FH patients and studied the association between these polymorphisms and CHD in Cox proportional hazards models. We confirmed the associations between four polymorphisms and CHD, the rs1151640 polymorphism in the olfactory receptor family 13 subfamily G member 1 (OR13G1) gene (HR 1.14, 95% CI 1.01-1.28, P = 0.03), the rs11881940 polymorphism in the heterogeneous nuclear ribonucleoprotein U-like 1 (HNRPUL1) gene (HR 1.27, 95% CI 1.07-1.51, P = 0.007), the rs3746731 polymorphism in the complement component 1 q subcomponent receptor 1 (CD93) gene (HR 1.26, 95% CI 1.06-1.49, P = 0.01), and the rs10757274 polymorphism near the cyclin-dependent kinase N2A and N2B (CDKN2A and CDKN2B) genes (HR 1.39, 95% CI 1.15-1.69, P < 0.001). Conclusion: We confirmed previously found associations between four polymorphisms and CHD, but refuted associations for six other polymorphisms in our large FH population. These findings stress the importance of replication before genetic information can be implemented in the prediction of CHD.

Abstract

This article describes the role of a committee in the Graduate School of Nursing at the University of Massachusetts, Worcester, that is referred to as the research advisory committee. It was developed to sustain the research mission, to facilitate faculty scholarship, and to provide a venue for presubmission grant review (hence called mock review) in a graduate school of nursing that is not considered "research intensive." We present its historical framework, the development of a mock review process, faculty accomplishments thus far, and our plans for the future. It is hoped that our experiences of building and supporting faculty research efforts in a research dynamic environment may provide guidance for others working in similar institutions.

Abstract

There is a real danger that measurable tasks and procedures can be misconstrued for nursing practice in contemporary healthcare organizations focused on the measurement of quality, safety, and productivity. This study uses the work of Patricia Benner to address the complex nature of nursing practice and discusses why the chief nursing officer must create an environment within the organization for the practice to be fully lived out if he or she is to be successful as the leader of the discipline.

Abstract

Purpose/Objectives: To apply the Hanahan and Weinberg conceptual framework for tumor development to the specific biomarkers observed or expressed in ovarian cancer. Data Sources: Data-based publications, topical reviews, and book chapters. Data Synthesis: Articles specific to ovarian cancer were reviewed to examine whether the six rules from the Hanahan and Weinberg conceptual framework were applicable to biomarkers of ovarian cancer. This approach allows for the application of a general framework for the development of solid tumors to the development of ovarian cancer. Conclusions: The six rules for tumor cell development outlined in the Hanahan and Weinberg conceptual framework are applicable to biomarkers expressed or observed in patients with ovarian cancer. Implications for Nursing: Oncology nurses can enhance their clinical teaching by integrating this information into their practice. Nurses who conduct research on ovarian cancer can use this framework to guide the selection of biomarker(s) for these studies. Finally, nurse educators can use this framework when teaching students key concepts in the care of patients with cancer.

Abstract

Reducing sex risk behaviors among high-risk injection drug users (IDUs) and crack smokers is a continuing challenge for HIV prevention. Based on a longitudinal study of sexually active Puerto Rican IDUs and crack smokers in New York (n=573) and Puerto Rico (n=264), baseline predictors of changes in sex risk (number of unprotected sex acts) at 6- and 36-month follow-up interviews were examined. In New York, predictors of higher sex risk were being younger, having primary partners, having more other sex partners, never exchanging sex, having lower self-efficacy for reducing sex risk behaviors and being HIV-negative, and these predictors were significant at both postbaseline periods. In Puerto Rico, short-term predictors included being male, having primary partners, never exchanging sex, lower sex risk norms and lower self-efficacy. However, only having primary partners was significant in longer-term behaviors. Results indicated the need for enhancing self-efficacy and for developing risk reduction strategies related to community differences.

Abstract

Objective. To analyze corporate governance arrangements and quality and financial performance outcomes among large multi-facility nursing home corporations (chains) that pursue stakeholder value (profit maximization) strategies. Study Design. To establish a foundation of knowledge about the focal phenomenon and processes, we conducted an historical (1993-2005) case study of one of the largest chains (Sun Helathcare Inc.) that triangulated qualitative and quantitative data sources. Data Sources. Two main sets of information were compared: (1) corporate sources including Sun's Security Exchange Commission (SEC) Form 10-K annual reports, industry financial reports, and the business press; and (2) external sources including, legal documents, press reports, and publicly available California facility cost reports and quality data. Principal Findings. Shareholder value was pursued at Sun through three inter-linked strategies: (1) rapid growth through debt-financed mergers; (2) labor cost constraint through low nurse staffing levels; and (3) a model of corporate governance that views sanctions for fraud and poor quality as a cost of business. Conclusions. Study findings and evidence from other large nursing home chains underscore calls from the Institute of Medicine and other bodies for extended oversight of the corporate governance and performance of large nursing home chains.

Abstract

Heart failure, a common syndrome in developed countries worldwide, is associated with poor quality of life, frequent rehospitalizations, and early death. Self-care is essential to improving outcomes in this patient population. The purpose of this article is to describe a situation-specific theory of heart failure self-care in which self-care is defined as a naturalistic decision-making process involving the choice of behaviors that maintain physiologic stability (maintenance) and the response to symptoms when they occur (management). Self-care maintenance is further defined to encompass routine symptom monitoring and treatment adherence. Self-care management is characterized as a process initiated by symptom recognition and evaluation, which stimulates the use of self-care treatments and treatment evaluation. Confidence in self-care is thought to moderate and/or mediate the effect of self-care on various outcomes. Four propositions were derived from the self-care of heart failure conceptual model: (1) symptom recognition is the key to successful self-care management; (2) self-care is better in patients with more knowledge, skill, experience, and compatible values; (3) confidence moderates the relationship between self-care and outcomes; and (4) confidence mediates the relationship between self-care and outcomes. These propositions were tested and supported using data obtained in previous research. Support of these propositions provides early evidence for this situation-specific theory of heart failure self-care.

Abstract

Recent epidemiological, biological, and behavioral evidence suggests that sleep disorders may contribute to the development of diabetes; conversely, diabetes itself may contribute to sleep disorders. Sleep appears to moderate the neurohormones that regulate blood glucose. Sleep deprivation and sleep disorders contribute to pathophysiological changes associated with the development of type 2 diabetes. In people who already have diabetes, sleep deprivation contributes to elevations of hemoglobin A1c. Symptoms that occur as a result of diabetes, such as nocturia and neuropathic pain, may in turn contribute to sleep disturbance and exacerbate sleep deprivation. The purposes of this article are to examine the scientific basis for the associations between diabetes and sleep, identify gaps in the understanding of the empirical underpinnings of these relationships, and propose directions for future research.
