Tanning and Cutaneous Malignancy

DERMATOLOGIC SURGERY, Issue 4 2008
SHERRIF F. IBRAHIM MD
BACKGROUND Exposure to ultraviolet radiation (UVR) results in a darkening of the skin known as tanning. Recently, it has been shown that tanning is a response to UVR-induced DNA damage and represents the skin's efforts to protect itself against further injury. Despite the link between UVR and cutaneous malignancy, people continue to pursue tanning from natural and artificial sources. This trend is reflected in the exponential rise in skin cancer incidence. OBJECTIVE The objective of this study was to review our current understanding of the factors controlling the tanning response and the relationship to cutaneous carcinogenesis, as well as the impact that the multibillion dollar tanning industry has had on the practice of dermatology. MATERIALS AND METHODS Extensive literature review was conducted in subjects related to tanning and the relationship to cutaneous malignancy. RESULTS Our knowledge of tanning and its effects on the skin has increased tremendously. It is clear that tanning contributes to the development of skin cancer. Despite this information, the incidence of skin cancer continues to increase exponentially. CONCLUSIONS Skin cancer poses a major public health concern and tanning remains the most modifiable risk factor in its etiology. Social, economic, and legislative issues have become tightly intertwined with the complex nature of human behavior in the continued pursuit of an activity that clearly has detrimental effects on one's health.

Diagnosis and management of geriatric insomnia: A guide for nurse practitioners

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 12 2008
MN (Nurse Practitioner), Preetha Krishnan RN
Abstract Purpose: To discuss the assessment, diagnosis, and management of geriatric insomnia, a challenging clinical condition of older adults frequently seen by primary care providers. Data sources: Extensive literature review of the published research articles and textbooks. Conclusions: Complaints of insomnia among older adults are frequently ignored, considered a part of the normal aging process or viewed as a difficult to treat condition. Geriatric insomnia remains a challenge for primary care providers because of the lack of evidence-based clinical guidelines and limited treatment options available. Effective management of this condition is necessary for improved quality of life, which is a primary issue for the elderly and their families. Therefore, geriatric insomnia warrants thorough attention from the nurse practitioners (NPs) who provide care for older adults. Implications for practice: Undiagnosed or under treated insomnia can cause increased risk for falls, motor vehicle accidents, depression, and shorter survival. Insomniacs double their risk for cardiovascular disease, stroke, cancer, and suicide compared to their counterparts. Insomnia is also associated with increased healthcare utilization and institutionalization. NPs could play a central role in reducing the negative consequences of insomnia through a systematic approach for diagnosis, evaluation, and management. [source]


Primary care health issues among men who have sex with men

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2006
Royal Gee MSN
Abstract Purpose: The purpose of the article is to examine "appropriate" health care for men who have sex with men (MSM), which is not to suggest "special" health care. As a group, MSM are at increased risk for sexually transmitted infections, anal cancer, and mental health disorders. Focus areas in this article will address health issues that the primary care nurse practitioner (NP) may encounter in clinical practice: anal carcinoma, sexually transmitted diseases (STDs), high-risk sexual practices, depression, and substance abuse were topics chosen for inclusion in this article. These topics were among those highlighted in the Healthy People 2010 Companion Document for LGBT Health, which served to examine the healthcare disparities and lack of access to needed services related to sexual orientation. Data source: Extensive literature review of research articles, journals, clinical practice guidelines, books, and public health department Internet Web sites. Conclusions: There are unique health disparities that exist for MSM related to social, emotional, and mental health factors, in addition to physical issues such as STDs. There is an increasing need for primary care providers to be aware of these disparities, as well as the factors that influence these disparities, in order to provide multidimensional care and health counseling that is unique to NP practice. Implications for practice: Both the primary care NP and the patient should be aware of the unique healthcare issues among MSM that should be incorporated into the patient's routine health maintenance program. As primary care providers, it is within the standards of practice for NPs to provide culturally competent care, along with health promotion and disease prevention for MSM. [source]


Benefits of Swim Training for Children and Adolescents with Asthma

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 6 2003
Cherri Rosimini ARNP
PURPOSE To r eview scientific evidence related to the benefits of swimming and present an evidence-based approach to prescribing swim training for children and adolescents with asthma. DATA SOURCES Extensive literature review of all research that has been done on swim training in asthmatic children and adolescents, using the databases CINAHL, Medline, and ProQuest. CONCLUSIONS When swimming is compared to other sports in the scientific literature, it has been found to have a lower asthmogenicity. It has also been shown to decrease the severity of asthma symptoms. Swimming may be an effective nonpharma-cological intervention for the child or adolescent with asthma. IMPLICATIONS FOR PRACTICE Research findings are summarized regarding the benefits of swim training on children and adolescents with asthma, and a stepped three-level approach to swim prescription is outlined along with safety recommendations.

Motivating Health: Strategies for the Nurse Practitioner

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 5 2003
Lynne S. Duran ARNP
Purpose To provide the nurse practitioner (NP) with a practical prescription for acquiring expertise in health behavior change using integrated principles from the transtheoretical model of change and motivational interviewing. Data Sources Extensive literature review of current theory and research on health behavior change. Conclusion Expertise in motivating health behavior change is essential to effective health promotion and to the NP role. Implications for Practice Lifestyle choices are principal contributors to the leading causes of death and most chronic diseases in the United States. Traditional health behavior interventions are often ineffective in motivating and sustaining lifestyle change. [source]


Cultivating problem-solving skills through problem-based approaches to professional development

HUMAN RESOURCE DEVELOPMENT QUARTERLY, Issue 3 2002
Margaret C. Lohman
An extensive literature review was conducted of four problem-based approaches to professional development: (1) case study, (2) goal-based scenario, (3) problem-based learning, and (4) action learning. The review comparatively analyzed the training designs of these four approaches and found key differences in the nature of their case problems and training strategies. Specifically, the analysis found that case problems are ill structured in action learning and problem-based learning, are moderately structured in a goal-based scenario, and are fairly well structured in the case study approach. In addition, it was found that prototypical problems are used to a much greater extent in the problem-based learning and goal-based scenario approaches than they are in the other two approaches. Furthermore, the analysis found that the case study approach uses the most expert-oriented training strategy, the goal-based scenario approach uses a more learner-oriented strategy than the case study approach, and the problem-based learning and action learning approaches use strongly learner-oriented strategies. These design differences suggest that the case study and goal-based scenario approaches are more likely to result in single-loop learning and to foster the ability to solve well-structured problems, whereas the problem-based learning and action learning approaches are more likely to lead to double-loop learning and to promote the ability to solve ill-structured problems. Implications of these findings for the design and research of problem-based approaches to professional development are discussed. [source]


Evaluating outpatient pharmacy services: a literature review of specialist heart failure services

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 1 2006
Tracey-Lea Hargraves Pharmacist (formerly)
Objective To identify appropriate methods to evaluate a specialist pharmacy service for heart failure patients in an ambulatory care setting. Method An extensive literature review was undertaken to identify the published data on evaluative studies of specialist pharmacy services, including those directed at heart failure patients in an ambulatory care model of service provision. Key findings Six studies were identified evaluating outpatient pharmacy services for heart failure. The pharmacy services provided in these settings were not well defined. The impact of the pharmacist was compared to ,usual care', that is care delivered without a pharmacist, by either a prospective randomised controlled trial (RCT), or before and after studies. In most cases the service was delivered by one pharmacist at one site. Services were primarily targeted at patients and focused on medication and lifestyle education, adverse drug reaction monitoring, and compliance/adherence. In all studies, there was a trend for improvement in the outcomes measured. Different study endpoints were examined, including process indicators such as compliance and outcome measures such as morbidity (clinical), quality of life (humanistic), and hospital admissions (economic). The ideal evaluative study would be an adequately powered, prospective, randomised controlled trial, comparing the effect of the pharmacist service to usual care (without the specified pharmacy service). Appropriate study endpoints including process indicators and outcome measures are needed. Identification of specific components and the extent of the service that would provide the most benefit to selected patient groups would be of interest. Conclusions Specialist ambulatory care pharmacy services have not been well defined or evaluated in the literature. Limited randomised controlled data exist. [source]


Does service failure influence customer loyalty?

JOURNAL OF CONSUMER BEHAVIOUR, Issue 3 2002
Francis Buttle
Abstract There is a general consensus that customer loyalty to service providers is not solely dependent upon their level of satisfaction or dissatisfaction. However, the identified antecedents of loyalty remain, at best, highly speculative. The aim of this extensive literature review is to give some understanding of the nature of customer loyalty and the antecedent effects of service dissatisfaction. The research reviewed suggests that customer loyalty is an attitudinal state, reflecting value, trust and commitment within supplier,customer relationships. Satisfaction is one of several antecedents of loyalty. A key influence on loyalty is the offer of unique value-delivering advantages not provided by competitors. Thus firms need to develop positive value-based exit barriers to achieve loyalty. When service failures occur, the recovery process is likely to have a greater impact on loyalty than the original service failure. The key to successful recoveries was found to be the customer's perception of ,fairness'. Recovery programmes must get it right first time. Customers who remain dissatisfied after a complaint has been handled are more dissatisfied than if no recovery attempt had been made. Dissatisfaction and customer satiation are major causes of a customer's exit. The solution to customer satiation is dynamic value creation. Collection and monitoring of customer data is needed for success and two-way communication is vital. Copyright © 2002 Henry Stewart Publications. [source]


HEALTH POLICY AND SYSTEMS: Critical Thinking of Nurse Managers Related to Staff RNs' Perceptions of the Practice Environment

JOURNAL OF NURSING SCHOLARSHIP, Issue 3 2010
NEA-BC, Susan Zori RN
Abstract Background Information and Significance: Critical thinking (CT) skills and the inclination to engage in critical thinking are essential for nurse managers to function as transformational leaders capable of influencing staff to align with organizational goals. In an extensive literature review, numerous studies were found examining the concept of CT in students and no studies were found exploring CT in nurse managers. Identifying the attributes, such as CT, that lead to success in the nurse manager role is useful when preparing nurse managers to lead effectively in the current healthcare climate. Research Question: Is there a difference between nurse managers' CT dispositions and their respective staff nurses' perceptions of the practice environment? Design: A convenience sample of 12 nurse managers and a random sample of 132 of their respective staff registered nurses (RNs) participated in this descriptive study. CT in nurse managers was measured by the California Critical Thinking Disposition Inventory (CCTDI). Staff RNs' perceptions of the practice environment were measured by the Practice Environment Scale (PES). The research question was answered using a t test. Findings: Significant (p < .001) differences were found between specific nurse managers' CCTDI scores for open-mindedness, analyticity, and critical thinking confidence, and significant differences (p < .01) were found for systematicity when compared with their respective staff RNs' mean subscale and overall PES scores. Conclusions: Results of the study support the positive relationship between strength in critical thinking dispositions of nurse managers and their respective staff RNs' perceptions of the practice environment. Nurse managers with stronger CT dispositions may be better able to create positive practice environments that are conducive to job satisfaction and thus the retention of staff RNs. Inclusion of strategies to support the development and use of CT in nurse managers is recommended. CT and other leadership attributes and skills including emotional and social intelligence and management of change through an appreciative inquiry process may provide opportunities to improve leadership effectiveness in nurse managers. Clinical Relevance: Enhancing critical thinking skills and dispositions of nurse managers may help to create positive work environments for staff RNs. Staff RNs who work in an environment perceived to be positive may be in a better position to deliver high quality, safe patient care. [source]


A Conceptual Framework for Hispanic Oral Health Care

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 1 2008
Gloria C. Mejia DDS
Abstract The need to study the health and health care determinants of US Hispanics is mandated by their rapid population growth. Nonetheless, it is challenging to study such a diverse population that incorporates many similarities and differences in values and experiences. This paper aims to highlight the factors that should be considered in Hispanic oral health research in the United States, and presents, in a theoretical framework, the relationships between these factors. The proposed ecological framework is supported by an extensive literature review, with an emphasis on the factors that are reported to differ among ethnic groups. It has a foundation in social science and is based on existing models from different fields of knowledge. To be comprehensive, the framework simultaneously addresses individual and environmental constructs. Within these, antecedent factors shape the intention to seek oral health care, while empowerment factors play a mediating role between intention and actual receipt of care. Individual antecedent factors incorporate risk markers, need, and predisposing factors. Environmental antecedent factors are represented by social constructs that allude to the population's health culture. Empowerment factors explain the level of control that a person perceives or the environment provides in receiving care. A thorough consideration of the factors that drive Hispanics' oral health care usage will aid US researchers and practitioners in improving this population's health and access to care. [source]


Pediatric systemic lupus erythematosus: Management issues in primary practice

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 6 2006
FNP (Instructor), Tiwaporn Pongmarutani MSN
Abstract Purpose: To provide nurse practitioners (NPs) with an update on pediatric systemic lupus erythematosus (SLE) with an emphasis on management considerations for primary care practitioners. Data sources: An extensive literature review was conducted using both Medline and CINAHL databases. Research articles reflecting the most compelling findings were included in this review. Conclusions: NPs who care for children with SLE may be able to prevent or delay the morbidities associated with this disease and its treatments, if they keep abreast of the new information evolving in this realm of rheumatologic diseases. Implications for practice: As more is learned about pediatric SLE, better treatments have evolved such that the survival rates have increased. The primary care of pediatric SLE patients that is focused on preventing or delaying SLE morbidities may help to restore, maintain, or improve the quality of life for these patients. [source]


Exploring the Appeal of Product Design: A Grounded, Value-Based Model of Key Design Elements and Relationships,

THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 5 2010
Charles H. Noble
Product design is increasingly being recognized as an important source of sustainable competitive advantage. Until recently, the domain of design has been loosely categorized as "form and function" issues. However, as this paper will explore, product design deals with a much richer range of issues, many of which have not been considered in the marketing literature. To explore the domain and elements of design, the paper begins with two major goals: (1) to elicit the key dimensions of design and to develop an enriched language for the understanding and study of design; and (2) to integrate the design dimensions within a broader model that ties initial design goals to eventual psychological and behavioral responses from consumers. To achieve these ends, grounded theory development is used by conducting an extensive literature review, in-depth interviews, and an interactive object elicitation technique. Drawing from this rich source of qualitative information as well as diverse literature fields, a framework is proposed for the creation of design value in consumer products. This framework not only explores the domain of design but also highlights the important elements of design that go well beyond the clichéd form and function issues. The resulting model reflects specific marketplace and organizational constraints that may help or impede the conversion of designer goals to so-called design levers. These levers are used to convey three types of values to consumers: rational, kinesthetic, and emotional. The framework then explains how and when these different values may be perceived by the consumer. Within this framework, testable research propositions and specific directions for future design-based research are also offered. Beyond its potential to spur marketing and new product development (NPD) management thought, the framework offered here represents a significant contribution to the field of design, which has historically been represented as a highly fragmented body of knowledge. Formalizing this framework should help overcome perhaps the largest obstacle to date to marketing-related and NPD-related research in this area,the lack of a detailed and consistent nomological view of the scope of design dimensions including testable linkages. Design has become an important tool that can be used by managers to develop dominant brands with lasting advantages. This research lends the NPD manager and the marketing manager better insights in into how this increasingly popular focus can be used to influence consumer behavior and firm success. "Design may be our top unexploited competitive edge." Tom Peters, 2004 (cover review of Norman, 2004) "We don't have a good language to talk about [design]. In most people's vocabularies, design means veneer., But to me, nothing could be further from the meaning of design. Design is the fundamental soul of a man-made creation."

Interspecific Competition and Niche Separation in Primates: A Global Analysis

BIOTROPICA, Issue 3 2009
Brian M. Schreier
ABSTRACT Primates are an extraordinarily well-known tropical forest, mammalian taxon. We investigated potential modes of niche separation in primates by identifying sympatric species with putatively similar niche characteristics and assessing potential competition using data gleaned from an extensive literature review. We defined competing species-pairs as (a) sympatric species in which (b) the body mass of the larger species was within 30 percent of the smaller species' mass and (c) the species had the same category of diet. A sample of 43 well-studied forests (7,20 per continent) provided 673 pairs of sympatric primate species. Of these, 45 pairs (7%) are potential competitors by our definition. Africa has the largest number of competing pairs (17 pairs), while Asia might have the highest percentage of competitors in each forest site (17%). Niche separation was investigated for each pair by examining them for each of eight possible modes of separation: detailed differences in diets (28% of potential competitors), use of different heights in the forest (25%), use of different types of forest (14%), use of different locations within the forest (11%), use of support branches of different diameters (7%), different ranging behavior (6%), different techniques of prey capture (4%), and differential timing of activity (4%). The use of different heights in the forest is the dominant form of potential separation in Africa (31% of competing species-pairs) and Asia (38%), while detailed differences in diet appears to be the primary mode of niche separation in the Americas (26%) and Madagascar (32%).

Single median maxillary central incisor: New data and mutation review

BIRTH DEFECTS RESEARCH, Issue 8 2007
Kênia B. El-Jaick
Abstract BACKGROUND: Single median maxillary central incisor (SMMCI) is a rare anomaly that may occur alone or associated with other conditions, frequently as part of the holoprosencephaly (HPE) spectrum. However, it has been suggested that SMMCI alone, or associated with some midline defects, may be considered a different entity from HPE (OMIM: 147250). Families with SMMCI, without HPE cases, are difficult to counsel for the risk of HPE in future generations because the same midline defects described as part of the "SMMCI syndrome" can also be part of the HPE spectrum. METHODS: We screened five cases of SMMCI for mutations in three HPE genes, SHH, TGIF, and SIX3. RESULTS: A missense mutation c.686C>T was found in the gene SIX3 of one patient, which did not differ from the accepted 20% of known HPE gene mutations among all HPE cases. Our results and an extensive literature review of gene mutations in patients with SMMCI showed that 27/28 of them were in HPE genes: SHH (n = 21), SIX3 (n = 3), TGIF (n = 1), GLI2 (n = 1), and PTCH (n = 1), and only one in the SALL4 gene. CONCLUSIONS: The clinical findings in patients with SMMCI without HPE in families with mutations in HPE genes cannot be distinguished from the findings reported in the SMMCI syndrome. Therefore, persons with SMMCI and their relatives should be carefully investigated for related midline disorders, especially of the HPE spectrum, and all known HPE genes screened.

Critical Aspects of Organizational Learning Research and Proposals for Its Measurement

BRITISH JOURNAL OF MANAGEMENT, Issue 2 2001
Satu Lähteenmäki
Based on an extensive literature review, this paper reveals several gaps in organizational learning (OL) research that need filling before we can really talk about a theory of organizational learning or verify the traits and very existence of learning organizations (LO) as a phenomenon. The critique, however, is not targeted at any single model or theory of organizational learning, but at theory building, which constantly drifts away with new definitions and approaches that break up rather than construct a theory. Despite the fact that numerous consultation tools for turning organizations into learning models have been developed and applied, the concept of organizational learning itself still remains vague and there is an urgent need for a holistic model of OL. Too much emphasis is put on studying the learning of individuals instead of concentrating on the learning of organizations. Since the theory is highly dispersed and does not really build on earlier findings, rich empirical studies are needed in order to validate measures of organizational learning. Modelling of the organizational learning process and clarification of how learning of individuals is turned into learning of organizations is needed. This paper introduces one set of OL measures developed to study whether organizational learning occurred during the operational and business culture change process of a single case company. Suggestions for further OL research are made on the basis of experiences gained when empirically testing this model. [source]


Phylogenetic relationships of the genera of Theaceae based on morphology

CLADISTICS, Issue 3 2004
Isolda Luna
This work represents the first phylogenetic analysis of all genera belonging to the plant family Theaceae (sensu lato). The study is based on 60 morphological characters derived from herbarium specimens and an extensive literature review of 37 genera (including the outgroup). In contrast to the results from molecular data, Theaceae is here found to consist of one clade in which the recognition of two families or subfamilies would leave Theaceae s.s. paraphyletic. Within that clade, Ternstroemiaceae is supported as monophyletic and includes Adinandra, Anneslea, Archboldiodendron, Balthasaria, Cleyera, Eurya, Euryodendron, Ficalhoa, Freziera, Symplococarpon, Ternstroemia and Visnea. The paraphyletic Theaceae s.s. includes Apterosperma, Camellia, Dankia, Gordonia, Pyrenaria, Schima, and Stewartia. Tetrameristaceae (Pentamerista and Tetramerista) are supported as a monophyletic family, with Pellicieraceae (Pelliciera) as sister group, and that clade is sister to the rest of the taxa. Bonnetiaceae (Archytaea and Bonnetia) and Kielmeyeroideae of the Clusiaceae (Caraipa, Haploclathra, Kielmeyera, Mahurea, Marila, and Neotatea) are also supported as monophyletic. Given the differences between the results obtained from morphological and molecular data, we consider that there is still a need for further research, including combined analyses. [source]
