ABSTRACT Objective: To develop a middle range nursing theory of impaired knowledge in individuals with heart failure. Methods: Descriptive study of the cross type developed through the theoretical-causal validity method, which used six steps for theory building: Definition of the construction approach; Definition of theoretical-conceptual models; Definition of main concepts; Development of a pictorial scheme; Construction of propositions; and Establishment of causal relations and evidence for practice. Results: Twenty-four articles were found, which identified two attributes, eight antecedents, and seven consequences, which gave rise to the pictogram, which schematized the concepts by relating them to cardiac physiology. Finally, 11 propositions and four causal relationships were created. Conclusion: The constructed theory enables a targeted driving of nurses’ clinical judgment regarding impaired knowledge in individuals with heart failure, culminating in individualized interventions to improve quality of life.

Care Deficit

A middle-range theory of heart failure self-care, derived from the self-care deficit theory of nursing, was tested among 175 Arab American older adults with heart failure. The middle-range theory achieved good statistical fit, but not all hypothesized relationships were supported. Specifically, conceptualizing basic conditioning factors as a single latent variable was not supported. However, individual factors of depression, social support, and time living with heart failure had a direct effect on both self-care agency and quality of life. Understanding predictors and outcomes of self-care within a theoretical framework is essential in caring for patients with heart failure.

В статье рассмотрены вопросы изменения качества жизни лиц пожилого и старческого возраста с ХСН и промежуточной ФВ (ХСНпрФВ) в процессе длительной (12 мес) фармакотерапии. Были обследованы 377 больных, из них 129 - 45-59 лет (средний возраст), 128 - 60-74 лет (пожилой возраст), 120 - 75 лет и старше (старческого возраста). Диагноз устанавливали в соответствии с Рекомендациями по диагностике и лечению ХСН (2013, 2016 г.) Проведена оценка качества жизни по опроснику MLHFQ. Установлено улучшение качества жизни через 12 мес терапии во всех группах больных, но наиболее выраженные результаты получены в старческом возрасте. Максимальное снижение уровня тревоги наблюдали у мужчин средней возрастной категории, у женщин - в пожилом возрасте. В пожилом и старческом возрасте отмечено сопоставимое снижение баллов по шкале депрессии Цунга как у мужчин, так и у женщин. The article deals with the issues of changing the quality of life of elderly and senile people with chronic heart failure with middle range ejection fraction (CHFmrHF) during long-term (12 months) pharmacotherapy. 377 patients were examined, including 129 people aged 45 to 59 years (middle age), 128 people aged 60 to 74 years (elderly), and 120 people aged over 75 years (senile age). The diagnosis was made in accordance with the Recommendations for the diagnosis and treatment of CHF (2013, 2016). The quality of life was assessed according to the MLHFQ questionnaire. There was an improvement in the quality of life after 12 months of therapy in all groups of patients, but the most pronounced results were obtained in old age. The maximum decrease in the level of anxiety was observed in men in the middle age group, in women - in the elderly. In the elderly and senile age, there was a comparable decrease in the scores on the Zung depression scale in both men and women.

Futility is defined as something unimportant, useless, ineffective, without value or purpose, frivolousness, unable to solve problems. The definition of futility is clear and simple; the difficultly is its clinical application in the management of complex cases. The implications are different when dealing with medical or surgical patients. It is radically different when the decision of not doing any other efforts for the treatment of intractable heart failure or disseminated carcinomatosis or when we are dealing with surgical patients whose diseases carry very low opportunity of survival or of improvement in his general wellbeing. It is in the medical cases that the strategy of hanging the Crepe is used when trying to communicate to the relatives the gravity of their beloved ones illness. At times the physicians exaggerate the seriousness of the disease to lessen the suffering if eventually the patient dies. Crepe is a black piece of cloth forming a bow that used to be placed in the front door of the house to indicate the death and mourning of the relatives. This custom has been abandoned in almost all countries. Physicians undertake the utmost efforts in trying to preserve the life of their patients as well as to provide quality of life no matter the economic circumstances. In recent years I had two patients who were so sick that their condition gave the impression that their lives were close to an end. Nevertheless, after an operation deemed by some other physicians as futile, both patients recovered and are leading a normal lives for the past six and five years respectively.

This article discusses the processes and implications of going beyond environment to context. The article (a) provides an operational definition of context; (b) describes a multidimensional model of context that views context as being multilevel, multifactorial, and interactive; (c) describes how conceptual models of quality of life, human rights, and human functioning can be used in conjunction with the multidimensional model of context to identify opportunities and develop context-based change strategies that improve quality of life, human rights, and human functioning outcomes; and (d) describes a four-step approach to leveraging an understanding of context to produce change. The article concludes with a discussion of the advantages of and barriers to moving beyond environment to context.

Background: There has been growing interest in meditation techniques as an intervention in chronic disease populations. Little is known of the effect meditation practice has on outcomes among patients with heart failure. Purpose: To identify and examine current literature on meditation interventions on heart failure outcomes. Method: The review utilized methods described by Whittemore and Knafl. Three electronic databases were searched through March 2018. Terms used were “mindfulness OR meditation” and “heart failure” in combination, generating 58 articles after duplicates were removed. After inclusion and exclusion criteria were applied, six studies qualified for review, including four articles with samples from the United States and two with samples from Brazil and Sweden, respectively. Results: Among the six studies in the final sample, the total number of participants was 320 heart failure patients. Interventional design and length varied among the studies, and 20 different dependent variables were identified. This study distinguished four categories of outcome measures with significant findings: psychosocial, biophysical, quality of life and heart failure symptom burden. Compared with controls meditation practice significantly improved depression ( p<.05), social support ( p<.05), biophysical factors and quality of life ( p<.05), in addition to reducing heart failure symptom burden. Across-study comparisons were limited due to variation in intervention definitions and designs. Additionally, the intervention dose and reporting method varied, limiting comparisons. The sample size in five out of six studies was fewer than 50 participants. Over 20 different measures were used across the six studies to measure outcome variables. Conclusion: Meditation may offer a patient-driven practice to reduce heart failure symptoms as well as improve psychosocial wellness and quality of life. Future research among heart failure patients should include the following: rigorous definition of meditation interventions, consistency in intervention characteristics, larger controlled trials, and standardized outcome instruments.

The Impact

Inequalities with respect to the distribution of societal resources can predispose people to vulnerability, which has led to a growing concern across America. The Federal Government has taken a leadership role and has launched several initiatives to combat health inequalities experienced by vulnerable populations. The National Institute of Health and all of its institutes, including the National Institute of Nursing Research, have written strategic plans to reduce, and ultimately, eliminate such health disparities. Nursing research has been conducted in the setting of vulnerable populations; several theoretical models for studying vulnerability have been created; and interventional studies designed to reduce health disparities have been implemented. This introduction includes the following: (a) a definition of the concept of vulnerability and health disparities; (b) a discussion of the conceptual models of vulnerability and health disparity and their applications; (c) a description of the impact of federal funding on vulnerable populations research; (d) a synopsis of the contributions made by nurse researchers in the field of vulnerable populations research; and (e) an overview of the volume.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).
