Many roads may lead to Rome: Selected features of quality control within environmental assessment systems in the US, NL, CA, and UK

DOE Office of Scientific and Technical Information (OSTI.GOV)

Günther, Markus, E-mail: markus.guenther@tu-berlin.de; Geißler, Gesa; Köppel, Johann

As there is no one-and-only concept on how to precisely define and establish quality control (QC) or quality assurance (QA) in the making of environmental assessments (EA), this paper presents selected features of international approaches that address quality in EA systems in the USA, the Netherlands, Canada, and the United Kingdom. Based on explanative case studies, we highlight the embedding of specific quality control features within the EA systems, the objectives and processes, and relevant transparency challenges. Such features of QC/QA approaches can be considered in cases where substantial quality control and assurance efforts are still missing. Yet further researchmore » needs to be conducted on the efficacy of these approaches, which remains beyond the scope of this study. - Highlights: • We present four tools for quality control and assurance from different EA systems. • Approaches vary in institutional setting, objectives, procedures, and transparency. • Highlighted features might provide guidance in cases where QC/QA is still lacking.« less

Observational evidence and strength of evidence domains: case examples

PubMed Central

2014-01-01

Background Systematic reviews of healthcare interventions most often focus on randomized controlled trials (RCTs). However, certain circumstances warrant consideration of observational evidence, and such studies are increasingly being included as evidence in systematic reviews. Methods To illustrate the use of observational evidence, we present case examples of systematic reviews in which observational evidence was considered as well as case examples of individual observational studies, and how they demonstrate various strength of evidence domains in accordance with current Agency for Healthcare Research and Quality (AHRQ) Evidence-based Practice Center (EPC) methods guidance. Results In the presented examples, observational evidence is used when RCTs are infeasible or raise ethical concerns, lack generalizability, or provide insufficient data. Individual study case examples highlight how observational evidence may fulfill required strength of evidence domains, such as study limitations (reduced risk of selection, detection, performance, and attrition); directness; consistency; precision; and reporting bias (publication, selective outcome reporting, and selective analysis reporting), as well as additional domains of dose-response association, plausible confounding that would decrease the observed effect, and strength of association (magnitude of effect). Conclusions The cases highlighted in this paper demonstrate how observational studies may provide moderate to (rarely) high strength evidence in systematic reviews. PMID:24758494

Berardinelli–Seip syndrome: highlight of treatment challenge

PubMed Central

Ferraria, Nélia; Pedrosa, Cristina; Amaral, Daniela; Lopes, Lurdes

2013-01-01

Berardinelli–Seip congenital lipodystrophy (BSCL) syndrome is a rare autosomal-recessive disease characterised by lipoatrophy and associated with deregulations of glycidic and lipid metabolism. We report three BSCL cases with its typical clinical picture and complications. Clinically, they all show marked atrophy of adipose tissue, acromegaly, acanthosis nigricans and tall stature. Two cases present attention deficit hyperactivity and developmental learning disorders; another patient has hypertrophic myocardiopathy and polycystic ovary syndrome. In all the cases AGPAT2 was the identified mutation. All the cases present hypertriglyceridemia. One case has developed hyperinsulinism controlled with metformin and another case already has type 2 diabetes with a difficult clinical control. There is no curative treatment and the current treatment options are based only on symptomatic control of the complications. Recently, published studies showed that leptin-replacement therapy appears a promising tool in the metabolic correction of BSCL complications, highlighting the importance of further investigations in BSCL treatment.

Re-defining one's occupational self 2 years after breast cancer: a case study.

PubMed

Newman, Robin M

2013-01-01

Margaret*, a 56 year-old Caucasian Stage III breast cancer survivor, participated in a 5 week occupational therapy pilot program, called Take Action. This program was designed for breast cancer survivors who self-reported changes in cognitive function following completion of chemotherapy. The goals of the program were to improve participants' knowledge and use of strategies to enhance occupational performance and to improve satisfaction and performance of meaningful daily activities or occupations. Through a client-centered and evidence-based approach, this case study highlights the importance of incorporating the survivors' sense of self into an occupation-based intervention. Occupational therapists play an important role in facilitating exploration of sense of self in the survivorship phase of care to support occupational performance in self care, productivity, work, leisure and social participation. This case study highlights the important work of redefining oneself in the survivorship phase of care. (*denotes name change).

2016-04-05

This analysis estimates the economic impacts of a wide variety of ecosystem restoration projects associated with U.S. Department of the Interior (DOI) lands and programs. Specifically, the report provides estimated economic impacts for 21 DOI restoration projects associated with Natural Resource Damage Assessment and Restoration cases and Bureau of Land Management lands. The study indicates that ecosystem restoration projects provide meaningful economic contributions to local economies and to broader regional and national economies, and, based on the case studies, we estimate that between 13 and 32 job-years4 and between $2.2 and $3.4 million in total economic output5 are contributed to the U.S. economy for every $1 million invested in ecosystem restoration. These results highlight the magnitude and variability in the economic impacts associated with ecosystem restoration projects and demonstrate how investments in ecosystem restoration support jobs and livelihoods, small businesses, and rural economies. In addition to providing improved information on the economic impacts of restoration, the case studies included with this report highlight DOI restoration efforts and tell personalized stories about each project and the communities that are positively affected by restoration activities. Individual case studies are provided in appendix 1 of this report and are available from an online database at https://www.fort.usgs.gov/economic-impacts-restoration.

Patterns of trauma induced by motorboat and ferry propellers as illustrated by three known cases from Rhode Island.

PubMed

Semeraro, Dominique; Passalacqua, Nicholas V; Symes, Steven; Gilson, Thomas

2012-11-01

Understanding patterns of trauma is important to determining cause and manner of death. A thorough evaluation of taphonomy, trauma, and bone fracture mechanisms is necessary to reconstruct the circumstances of the death. This study examines the skeletal trauma caused by boat propeller strikes in terms of wound characteristics and location based on three cases from Rhode Island. These case studies review the traumatic characteristics caused by propeller injuries and highlight the anatomic regions most likely to sustain skeletal trauma. With this information, investigators may be able to identify propeller trauma even in severely decomposed remains. The discussion of boat propeller trauma also raises issues regarding how forensic anthropologists and forensic pathologists classify trauma (specifically blunt force vs. sharp) and highlights semantic issues arising in trauma classification. The study also discusses why these propeller cases should be classified as blunt trauma rather than sharp or chop/hack trauma. Ultimately, the authors urge consistency and communication between pathologist and forensic anthropologists performing trauma analyses. © 2012 American Academy of Forensic Sciences.

2017-10-01

Objectives With the widespread use of DNA testing, police, death investigators, and attorneys need to be aware of the capabilities of this technology. This review provides an overview of scenarios where DNA evidence has played a major role in homicide investigations in order to highlight important educational issues for police, death investigators, forensic pathologists, and attorneys. Methods This was a nonrandom, observational, retrospective study. Data were obtained from the collective files of the authors from casework during a 15-year period, from 2000 through 2014. Results A series of nine scenarios, encompassing 11 deaths, is presented from the standpoint of the police and death investigation, the forensic pathology autopsy performance, the subsequent DNA testing of evidence, and, ultimately, the final adjudication of cases. Details of each case are presented, along with a discussion that focuses on important aspects of sample collection for potential DNA testing, especially at the crime scene and the autopsy. The presentation highlights the diversity of case and evidence types in which DNA testing played a valuable role in the successful prosecution of the case. Conclusions By highlighting homicides where DNA testing contributed to the successful adjudication of cases, police, death investigators, forensic pathologists, and attorneys will be better informed regarding the types of evidence and situations where such testing is of potential value.

The Interacting Axes of Environmental, Health, and Social Justice Cumulative Impacts: A Case Study of the Blueberry River First Nations

PubMed Central

Gislason, Maya K; Andersen, Holly K

2016-01-01

We consider the case of intensive resource extractive projects in the Blueberry River First Nations in Northern British Columbia, Canada, as a case study. Drawing on the parallels between concepts of cumulative environmental and cumulative health impacts, we highlight three axes along which to gauge the effects of intensive extraction projects. These are environmental, health, and social justice axes. Using an intersectional analysis highlights the way in which using individual indicators to measure impact, rather than considering cumulative effects, hides the full extent by which the affected First Nations communities are impacted by intensive extraction projects. We use the case study to contemplate several mechanisms at the intersection of these axes whereby the negative effects of each not only add but also amplify through their interactions. For example, direct impact along the environmental axis indirectly amplifies other health and social justice impacts separately from the direct impacts on those axes. We conclude there is significant work still to be done to use cumulative indicators to study the impacts of extractive industry projects—like liquefied natural gas—on peoples, environments, and health.

2015-01-01

Broad international guidelines and studies in the context of individual clinical trials highlight the centrality of community stakeholder engagement in conducting ethically rigorous HIV prevention trials. We explored and identified challenges and facilitators for community stakeholder engagement in biomedical HIV prevention trials in diverse global settings. Our aim was to assess and deepen the empirical foundation for priorities included in the GPP guidelines and to highlight challenges in implementation that may merit further attention in subsequent GPP iterations. From 2008-2012 we conducted an embedded, multiple case study centered in Thailand, India, South Africa and Canada. We conducted in-depth interviews and focus groups with respondents from different trial-related subsystems: civil society organization representatives, community advocates, service providers, clinical trialists/researchers, former trial participants, and key HIV risk populations. Interviews/focus groups were recorded, and coded using thematic content analysis. After intra-case analyses, we conducted cross-case analysis to contrast and synthesize themes and sub-themes across cases. Lastly, we applied the case study findings to explore and assess UNAIDS/AVAC GPP guidelines and the GPP Blueprint for Stakeholder Engagement. Across settings, we identified three cross-cutting themes as essential to community stakeholder engagement: trial literacy, including lexicon challenges and misconceptions that imperil sound communication; mistrust due to historical exploitation; and participatory processes: engaging early; considering the breadth of "community"; and, developing appropriate stakeholder roles. Site-specific challenges arose in resource-limited settings and settings where trials were halted. This multiple case study revealed common themes underlying community stakeholder engagement across four country settings that largely mirror GPP goals and the GPP Blueprint, as well as highlighting challenges in the implementation of important guidelines. GPP guidance documents could be strengthened through greater focus on: identifying and addressing the community-specific roots of mistrust and its impact on trial literacy activities; achieving and evaluating representativeness in community stakeholder groups; and addressing the impact of power and funding streams on meaningful engagement and independent decision-making.

Objectives Broad international guidelines and studies in the context of individual clinical trials highlight the centrality of community stakeholder engagement in conducting ethically rigorous HIV prevention trials. We explored and identified challenges and facilitators for community stakeholder engagement in biomedical HIV prevention trials in diverse global settings. Our aim was to assess and deepen the empirical foundation for priorities included in the GPP guidelines and to highlight challenges in implementation that may merit further attention in subsequent GPP iterations. Methods From 2008–2012 we conducted an embedded, multiple case study centered in Thailand, India, South Africa and Canada. We conducted in-depth interviews and focus groups with respondents from different trial-related subsystems: civil society organization representatives, community advocates, service providers, clinical trialists/researchers, former trial participants, and key HIV risk populations. Interviews/focus groups were recorded, and coded using thematic content analysis. After intra-case analyses, we conducted cross-case analysis to contrast and synthesize themes and sub-themes across cases. Lastly, we applied the case study findings to explore and assess UNAIDS/AVAC GPP guidelines and the GPP Blueprint for Stakeholder Engagement. Results Across settings, we identified three cross-cutting themes as essential to community stakeholder engagement: trial literacy, including lexicon challenges and misconceptions that imperil sound communication; mistrust due to historical exploitation; and participatory processes: engaging early; considering the breadth of “community”; and, developing appropriate stakeholder roles. Site-specific challenges arose in resource-limited settings and settings where trials were halted. Conclusions This multiple case study revealed common themes underlying community stakeholder engagement across four country settings that largely mirror GPP goals and the GPP Blueprint, as well as highlighting challenges in the implementation of important guidelines. GPP guidance documents could be strengthened through greater focus on: identifying and addressing the community-specific roots of mistrust and its impact on trial literacy activities; achieving and evaluating representativeness in community stakeholder groups; and addressing the impact of power and funding streams on meaningful engagement and independent decision-making.

Histopathologic Findings in Autopsies with Emphasis on Interesting and Incidental Findings-A Pathologist's Perspective.

PubMed

Patel, Sapna; Rajalakshmi, B R; Manjunath, G V

2016-11-01

Autopsy aids to the knowledge of pathology by unveiling the rare lesions which are a source of learning from a pathologist's perspective Some of them are only diagnosed at autopsy as they do not cause any functional derangement. This study emphasizes the various incidental lesions which otherwise would have been unnoticed during a person's life. The aim of this study was to determine the spectrum of histopathological findings including neoplastic lesions related or unrelated to the cause of death. It was also aimed to highlight various incidental and interesting lesions in autopsies. A retrospective study of medicolegal autopsies for six years was undertaken in a tertiary care centre to determine the spectrum of histopathological findings including neoplastic lesions related or unrelated to the cause of death and to highlight various incidental and interesting lesions in autopsies. Statistical Analysis: Individual lesions were described in numbers and incidence in percentage. The study consisted of a series of 269 autopsy cases and histopathological findings were studied only in 202 cases. The commonest cause of death was pulmonary oedema. The most common incidental histopathological finding noted was atherosclerosis in 55 (27.2%) cases followed by fatty liver in 40 (19.8%) cases. Neoplastic lesions accounted for 2.47% of cases. This study has contributed a handful of findings to the pool of rare lesions in pathology. Some of these lesions encountered which served as feast to a pathologist are tumour to tumour metastasis, a case with coexistent triple lesions, Dubin Johnson syndrome, von Meyenburg complex, Multilocular Cystic Renal Cell Carcinoma (MCRCC), Autosomal Dominant Polycystic Kidney Disease (ADPKD), liver carcinod and an undiagnosed vaso-occlusive sickle cell crisis. Autopsy studies help in the detection of unexpected findings significant enough to have changed patient management had they been recognized before death.

Using the Advocacy Coalition Framework and Multiple Streams policy theories to examine the role of evidence, research and other types of knowledge in drug policy.

PubMed

Ritter, Alison; Hughes, Caitlin Elizabeth; Lancaster, Kari; Hoppe, Robert

2018-04-17

The prevailing 'evidence-based policy' paradigm emphasizes a technical-rational relationship between alcohol and drug research evidence and subsequent policy action. However, policy process theories do not start with this premise, and hence provide an opportunity to consider anew the ways in which evidence, research and other types of knowledge impact upon policy. This paper presents a case study, the police deployment of drug detection dogs, to highlight how two prominent policy theories [the Advocacy Coalition Framework (ACF) and the Multiple Streams (MS) approach] explicate the relationship between evidence and policy. The two theories were interrogated with reference to their descriptions and framings of evidence, research and other types of knowledge. The case study methodology was employed to extract data concerned with evidence and other types of knowledge from a previous detailed historical account and analysis of drug detection dogs in one Australian state (New South Wales). Different types of knowledge employed across the case study were identified and coded, and then analysed with reference to each theory. A detailed analysis of one key 'evidence event' within the case study was also undertaken. Five types of knowledge were apparent in the case study: quantitative program data; practitioner knowledge; legal knowledge; academic research; and lay knowledge. The ACF highlights how these various types of knowledge are only influential inasmuch as they provide the opportunity to alter the beliefs of decision-makers. The MS highlights how multiple types of knowledge may or may not form part of the strategy of policy entrepreneurs to forge the confluence of problems, solutions and politics. Neither the Advocacy Coalition Framework nor the Multiple Streams approach presents an uncomplicated linear relationship between evidence and policy action, nor do they preference any one type of knowledge. The implications for research and practice include the contestation of evidence through beliefs (Advocacy Coalition Framework), the importance of venues for debate (Advocacy Coalition Framework), the way in which data and indicators are transformed into problem specification (Multiple Streams) and the importance of the policy ('alternatives') stream (Multiple Streams). © 2018 Society for the Study of Addiction.

Team science research has indicated that trust is a critical variable of teamwork, contributing greatly to a team's performance. Trust has long been examined in health care with research focusing on the development of trust by patients with their health care practitioners. Studies have indicated that trust is linked to patient satisfaction, adherence to treatment, continuity of care, and improved outcomes. We explore the construct of trust using a case example of a patient who received a surgical procedure for a precancerous polyp. We apply the principle of trust to the case as well as present the literature on trust and key definitions for understanding trust. Additionally, we apply the definitions presented to the specific case example by highlighting moments where trust is developed or violated. Lastly, we offer insights to health care practitioners on the development of trust in their own patient interactions to improve care.

Enhancing Schistosomiasis Control Strategy for Zimbabwe: Building on Past Experiences

PubMed Central

Chimbari, Moses J.

2012-01-01

Schistosoma haematobium and Schistosoma mansoni are prevalent in Zimbabwe to levels that make schistosomiasis a public health problem. Following three national surveys to map the disease prevalence, a national policy on control of schistosomiasis and soil transmitted helminths is being developed. This paper reviews the experiences that Zimbabwe has in the area of schistosomiasis control with a view to influence policy. A case study approach to highlight key experiences and outcomes was adopted. The benefits derived from intersectoral collaboration that led to the development of a model irrigation scheme that incorporates schistosomiasis control measures are highlighted. Similarly, the benefits of using plant molluscicides and fish and duck biological agents (Sargochromis codringtonii and Cairina moschata) are highlighted. Emphasis was also placed on the importance of utilizing locally developed water and sanitation technologies and the critical human resource base in the area of schistosomiasis developed over years. After synthesis of the case studies presented, it was concluded that while there is a need to follow the WHO recommended guidelines for schistosomiasis control it is important to develop a control strategy that is informed by work already done in the country. The importance of having a policy and local guidelines for schistosomiasis control is emphasized. PMID:22655171

2014-09-01

The energy of patients and members of the public worldwide who care about improving health is a huge, but still largely unrecognized and untapped, resource. The aim of patient engagement is to shift the clinical paradigm from determining "what is the matter?" to discovering "what matters to you?" This article presents four case studies from around the world that highlight the proven and potential abilities of increased patient engagement to improve health outcomes and reduce costs, while extending the reach of treatment and diagnostic programs into the community. The cases are an online mental health community in the United Kingdom, a genetic screening program in the United Arab Emirates, a World Health Organization checklist for new mothers, and a hospital-based patient engagement initiative in the United States. Evidence from these and similar endeavors suggests that closer collaboration on the part of patients, families, health care providers, health care systems, and policy makers at multiple levels could help diverse nations provide more effective and population-appropriate health care with fewer resources.

American tegumentary leishmaniasis is endemic in the State of Paraná, with 99.3% of the cases reported in the South of Brazil. Spatial distribution of the disease in northern Paraná was verified, identifying the most relevant geographic areas in epidemiological terms. The study used data recorded on epidemiological forms from the Teaching and Research Clinical Test Laboratory of the State University in Maringá, from 1987 to 2004. The study only included individuals that were infected in the municipalities (counties) in northern Paraná. Identification of the epidemiological units (poles and circuits) was based on spatial density of cases, according to the model proposed by the National Health Foundation, considering the most likely infection sites. Considering 1,933 reported cases, 1,611 were infected in northern Paraná. American tegumentary leishmaniasis distribution in Paraná State suggests two circuits for production of the disease: Paraná-Paranapanema, highlighting the Cinzas-Laranjinha, Tibagi, Ivaí-Pirapó, Piquiri, and Baixo Iguaçu poles, and Ribeira, highlighting the Alto Ribeira pole.

Case Studies in Modelling, Control in Food Processes.

PubMed

Glassey, J; Barone, A; Montague, G A; Sabou, V

This chapter discusses the importance of modelling and control in increasing food process efficiency and ensuring product quality. Various approaches to both modelling and control in food processing are set in the context of the specific challenges in this industrial sector and latest developments in each area are discussed. Three industrial case studies are used to demonstrate the benefits of advanced measurement, modelling and control in food processes. The first case study illustrates the use of knowledge elicitation from expert operators in the process for the manufacture of potato chips (French fries) and the consequent improvements in process control to increase the consistency of the resulting product. The second case study highlights the economic benefits of tighter control of an important process parameter, moisture content, in potato crisp (chips) manufacture. The final case study describes the use of NIR spectroscopy in ensuring effective mixing of dry multicomponent mixtures and pastes. Practical implementation tips and infrastructure requirements are also discussed.

PubMed

Moll, Sandra

2012-01-01

The purpose of this paper is to examine key challenges associated with conducting politically sensitive research within a workplace setting, and to highlight strategic partnerships that can be developed to address these challenges. The author's research on employee mental health issues within a large healthcare facility serves as the foundation for identification and description of "political minefields" that investigators may encounter when conducting organizational case study research. Key methodological principles from the literature on qualitative case study research will frame discussion of how to understand and address political sensitivities in the research process. The benefits of conducting organizational case study research will be outlined, followed by discussion of methodological challenges that can emerge in negotiating entry, collecting data (gatekeepers, researcher reflexivity, participant authenticity and non-maleficence), and communicating research findings. Courage, collaboration and clear communication with stakeholders at all levels of the organization are critical to the success of workplace based case study research.

Hair highlights and severe acute irritant dermatitis ("burn") of the scalp.

PubMed

Chan, Heidi P; Maibach, Howard I

2010-12-01

These days, most celebrities--young and old--have their hair highlighted. That is why it is not surprising that even the youth have their hair highlighted as they emulate their favorite actors, unaware of the harmful consequences of this unsafe procedure. Hair highlighting involves decolorizing melanin pigments of select hair strands through an oxidation reaction under alkaline conditions by the active ingredients of the highlighting mixture--hydrogen peroxide, persulfates, and metasilicate. Hydrogen peroxide and the persulfates are flammable, necessitating that regulatory bodies (namely, the U.S. Food and Drug Administration [FDA] and the Cosmetic Ingredient Review [CIR] Expert Panel, the European Union's (EU), European Economic Community [EEC] directives, the Australian government's National Industrial Chemicals Notification and Assessment Scheme [NICNAS], and the Association of Southeast Asian Nations [ASEAN]) to regulate the permissible amounts of these chemicals in hair highlighting products. To review published case reports of resulting in severe acute irritant dermatitis ("burns") of the scalp caused by hair highlighting, to explain why these scalp burns happen, to identify preventive measures to avoid such occurrences, and to discuss the implications for society. We searched medical and scientific search engines and used keywords such as hair highlights, scalp burn, and other related terms.. Six articles were obtained, yielding 8 reported cases (2 of the 6 articles had 2 cases each) of hair highlighting resulting in scalp burns; these 8 cases were reviewed and analyzed. Five of the 8 patients belonged to the pediatric age group. The causes of scalp burn were classified into 2 categories: chemical (caustic nature of the highlighting mixture, spillage of the hot mixture, toxic reaction to the dyes) and thermal (by contact of the scalp with overheated aluminum foil and by the blow dryer). The 5 pediatric patients in the group unnecessarily suffered pain and embarrassment caused by this procedure, as well as the risk of developing malignancy in the future. Hairstylists play a large role in the occurrence of scalp burns. Thus, they need to be careful and knowledgeable of the caustic nature of the highlighting mixture and the potential harm these chemicals may cause. The authors strongly propose that the relevant regulatory bodies review the permissible levels of the caustic chemicals, and that this unsafe procedure should be performed only on adults.

Splenic manifestations of chronic autoimmune disorder: a report of five cases with histiocytic necrotizing change in four cases.

PubMed

Auerbach, Aaron; Summers, Thomas A; Zhang, Binxue; Aguilera, Nadine S

2013-07-01

Autoimmune diseases (AD) are associated with lymphadenopathy and splenomegaly. Changes in the spleen have not been characterized completely in AD; we describe splenectomy specimens from five patients with chronic AD, highlighting the presence of necrotizing histiocytosis. Of the patients (three males and two females; mean 40 years), four had systemic lupus erythematosus; one had rheumatoid arthritis. All had moderate splenomegaly (213-803 g, mean 421 g). Four cases exhibited necrosis with apoptosis and karyorrhectic debris occurring in the white pulp and minimal acute inflammation; one showed florid follicular hyperplasia. Splenic involvement ranged from focal to extensive. Plasma cells were negative for IgG4. Haematoxylin bodies were not identified. Stains for infectious organisms were negative. Immunohistochemical studies showed that lymphocytes surrounding the necrosis were a mixture of CD4(+) and CD8(+) T cells; CD123-positive plasmacytoid dendritic cells were not present, and staining for kappa and lambda light chains showed no clonality. 16S rDNA PCR was performed; no amplification was seen in three of four cases tested for bacteria specific rDNA. Epstein-Barr virus-encoded RNA (EBER) in situ hybridization studies highlighted rare positive cells in four cases. Splenomegaly in AD is thought to be hyperplasic, but we present four cases showing histiocytic necrosis, a finding which should be considered part of the spectrum of AD in the spleen. © 2013 John Wiley & Sons Ltd.

Dyadic heart failure care types: qualitative evidence for a novel typology.

PubMed

Buck, Harleah G; Kitko, Lisa; Hupcey, Judith E

2013-01-01

Compared with other chronic illness populations, relatively little is known about heart failure (HF) patient and caregiver spousal/partner dyads and what effect dyadic interactions have on self-care. The aim of this study was to present a new typology of patient and caregiver dyadic interdependence in HF care, presenting exemplar cases of each type: patient oriented, caregiver oriented, collaboratively oriented, complementarily oriented. Stake's instrumental case study methodology was used. Interviews were unstructured, consisting of open-ended questions exploring dyad's experiences with HF, audiorecorded, and transcribed. Cases were selected because they exhibited the necessary characteristics and also highlighted a unique, little understood variation in self-care practice. Each case represents a dyad's discussion of caring for HF in their normal environment. From 19 dyads, 5 exemplar case studies illustrate the 4 dyadic types. A fifth, incongruent case, defined as a case where the patient and caregiver indicated incongruent dyadic types, was included to highlight that not all dyads agree on their type. A major theme of Sharing Life infused all of the dyad's narratives. This typology advances the science of dyadic interdependence in HF self-care, explains possible impact on outcomes, and is an early theoretical conceptualization of these complex and dynamic phenomena. The cases illustrate how long-term dyads attempt to share the patient's HF care according to established patterns developed over the trajectory of their relationship. In keeping with the interdependence theory, these couples react to the patient's declining ability to contribute to his/her own care by maintaining their habitual pattern until forced to shift. This original pattern may or may not have involved the dyad working together. As the patient's dependence on the caregiver increases, the caregiver must decide whether to react out of self-interest or the patient's interest. Continued study of the typology is needed in nonspousal/partner dyads.

Histopathologic Findings in Autopsies with Emphasis on Interesting and Incidental Findings-A Pathologist’s Perspective

PubMed Central

Rajalakshmi, B.R.; Manjunath, G.V.

2016-01-01

Introduction Autopsy aids to the knowledge of pathology by unveiling the rare lesions which are a source of learning from a pathologist’s perspective Some of them are only diagnosed at autopsy as they do not cause any functional derangement. This study emphasizes the various incidental lesions which otherwise would have been unnoticed during a person’s life. Aim The aim of this study was to determine the spectrum of histopathological findings including neoplastic lesions related or unrelated to the cause of death. It was also aimed to highlight various incidental and interesting lesions in autopsies. Materials and Methods A retrospective study of medicolegal autopsies for six years was undertaken in a tertiary care centre to determine the spectrum of histopathological findings including neoplastic lesions related or unrelated to the cause of death and to highlight various incidental and interesting lesions in autopsies. Statistical Analysis: Individual lesions were described in numbers and incidence in percentage. Results The study consisted of a series of 269 autopsy cases and histopathological findings were studied only in 202 cases. The commonest cause of death was pulmonary oedema. The most common incidental histopathological finding noted was atherosclerosis in 55 (27.2%) cases followed by fatty liver in 40 (19.8%) cases. Neoplastic lesions accounted for 2.47% of cases. Conclusion This study has contributed a handful of findings to the pool of rare lesions in pathology. Some of these lesions encountered which served as feast to a pathologist are tumour to tumour metastasis, a case with coexistent triple lesions, Dubin Johnson syndrome, von Meyenburg complex, Multilocular Cystic Renal Cell Carcinoma (MCRCC), Autosomal Dominant Polycystic Kidney Disease (ADPKD), liver carcinod and an undiagnosed vaso-occlusive sickle cell crisis. Autopsy studies help in the detection of unexpected findings significant enough to have changed patient management had they been recognized before death. PMID:28050373

We present results from life history interviews with 60 young adults from southern Uganda. Using a novel qualitative case-control design, we compared newly HIV-positive cases with HIV-negative controls matched on age, gender, marital status, and place of residence. Relationship context was the most salient theme differentiating cases from controls. Compared with HIV-negative respondents, recent seroconverters described relationships marked by poorer communication, greater suspicion and mistrust, and larger and more transitory sexual networks. Results highlight the importance of dyadic approaches to HIV and possibly of couple-based interventions. Using HIV-matched pairs allowed additional understanding of the factors influencing transmission. This hybrid methodological approach holds promise for future studies of sexual health.

The European politics of animal experimentation: From Victorian Britain to 'Stop Vivisection'.

PubMed

Germain, Pierre-Luc; Chiapperino, Luca; Testa, Giuseppe

2017-08-01

This paper identifies a common political struggle behind debates on the validity and permissibility of animal experimentation, through an analysis of two recent European case studies: the Italian implementation of the European Directive 2010/63/EC regulating the use of animals in science, and the recent European Citizens' Initiative (ECI) 'Stop Vivisection'. Drawing from a historical parallel with Victorian antivivisectionism, we highlight important threads in our case studies that mark the often neglected specificities of debates on animal experimentation. From the representation of the sadistic scientist in the XIX century, to his/her claimed capture by vested interests and evasion of public scrutiny in the contemporary cases, we show that animals are not simply the focus of the debate, but also a privileged locus at which much broader issues are being raised about science, its authority, accountability and potential misalignment with public interest. By highlighting this common socio-political conflict underlying public controversies around animal experimentation, our work prompts the exploration of modes of authority and argumentation that, in establishing the usefulness of animals in science, avoid reenacting the traditional divide between epistemic and political fora.

Health for All? Sexual Orientation, Gender Identity, and the Implementation of the Right to Access to Health Care in South Africa.

PubMed

Müller, Alexandra

2016-12-01

The framework of health and human rights provides for a comprehensive theoretical and practical application of general human rights principles in health care contexts that include the well-being of patients, providers, and other individuals within health care. This is particularly important for sexual and gender minority individuals, who experience historical and contemporary systematical marginalization, exclusion, and discrimination in health care contexts. In this paper, I present two case studies from South Africa to (1) highlight the conflicts that arise when sexual and gender minority individuals seek access to a heteronormative health system; (2) discuss the international, regional, and national human rights legal framework as it pertains to sexual orientation, gender identity, and health; and (3) analyze the gap between legislative frameworks that offer protection from discrimination based on sexual orientation and gender identity and their actual implementation in health service provision. These case studies highlight the complex and intersecting discrimination and marginalization that sexual and gender minority individuals face in health care in this particular context. The issues raised in the case studies are not unique to South Africa, however; and the human rights concerns illustrated therein, particularly around the right to health, have wide resonance in other geographical and social contexts.

Abstract The framework of health and human rights provides for a comprehensive theoretical and practical application of general human rights principles in health care contexts that include the well-being of patients, providers, and other individuals within health care. This is particularly important for sexual and gender minority individuals, who experience historical and contemporary systematical marginalization, exclusion, and discrimination in health care contexts. In this paper, I present two case studies from South Africa to (1) highlight the conflicts that arise when sexual and gender minority individuals seek access to a heteronormative health system; (2) discuss the international, regional, and national human rights legal framework as it pertains to sexual orientation, gender identity, and health; and (3) analyze the gap between legislative frameworks that offer protection from discrimination based on sexual orientation and gender identity and their actual implementation in health service provision. These case studies highlight the complex and intersecting discrimination and marginalization that sexual and gender minority individuals face in health care in this particular context. The issues raised in the case studies are not unique to South Africa, however; and the human rights concerns illustrated therein, particularly around the right to health, have wide resonance in other geographical and social contexts.

The Use of Case Studies in Teaching Undergraduate Neuroscience

PubMed Central

Meil, William M.

2007-01-01

Case studies have been the cornerstone of many discoveries in neurology and continue to be an indispensable source of knowledge. Attaching a name, face, and story to the study of neurological disorders makes them more “real” and memorable. This article describes the value of the case study methodology and its advantages as a pedagogical approach. It also illustrates how the seminal case of H.M. can be used to highlight the advantages and disadvantages of the case study methodology. Three exercises are described for incorporating case studies into neuroscience courses. The first exercise requires students to conduct a literature review regarding their assigned case and then design an experiment to address a lingering question regarding that neurological disorder. Survey results of 90 students provide quantitative and qualitative support for this approach. The vast majority of students indicated this exercise was a valuable learning experience; sparked interest in the topic and in biopsychology; increased their knowledge and stimulated critical thinking. The second exercise discusses how students might conduct their own case studies. The third exercise emphasizes the use of case studies as a platform to examine competing hypotheses regarding neurological conditions and their treatment. A table listing case studies appropriate for undergraduate neuroscience courses is included. Cases are categorized by the type of neurological disorder and notes regarding the nature of and content of each case are provided. PMID:23493154

Wilson, James C; Thorne, Michael C; Towler, George; Norris, Simon

2011-12-01

Many countries have a programme for developing an underground geological disposal facility for radioactive waste. A case study is provided herein on the illustrative assessment of human health issues arising from the potential release of chemotoxic and radioactive substances from a generic geological disposal facility (GDF) for radioactive waste. The illustrative assessment uses a source-pathway-receptor methodology and considers a number of human exposure pathways. Estimated exposures are compared with authoritative toxicological assessment criteria. The possibility of additive and synergistic effects resulting from exposures to mixtures of chemical contaminants or a combination of radiotoxic and chemotoxic substances is considered. The case study provides an illustration of how to assess human health issues arising from chemotoxic species released from a GDF for radioactive waste and highlights potential difficulties associated with a lack of data being available with which to assess synergistic effects. It also highlights how such difficulties can be addressed.

Seagrass meadows globally as a coupled social-ecological system: implications for human wellbeing.

Cullen-Unsworth, Leanne C; Nordlund, Lina Mtwana; Paddock, Jessica; Baker, Susan; McKenzie, Len J; Unsworth, Richard K F

2014-06-30

Seagrass ecosystems are diminishing worldwide and repeated studies confirm a lack of appreciation for the value of these systems. In order to highlight their value we provide the first discussion of seagrass meadows as a coupled social-ecological system on a global scale. We consider the impact of a declining resource on people, including those for whom seagrass meadows are utilised for income generation and a source of food security through fisheries support. Case studies from across the globe are used to demonstrate the intricate relationship between seagrass meadows and people that highlight the multi-functional role of seagrasses in human wellbeing. While each case underscores unique issues, these examples simultaneously reveal social-ecological coupling that transcends cultural and geographical boundaries. We conclude that understanding seagrass meadows as a coupled social-ecological system is crucial in carving pathways for social and ecological resilience in light of current patterns of local to global environmental change.

Eichel, Paul H.; Ghiglia, Dennis C.; Jakowatz, Jr., Charles V.

1990-01-01

A phase gradient autofocus system for use in synthetic aperture imaging accurately compensates for arbitrary phase errors in each imaged frame by locating highlighted areas and determining the phase disturbance or image spread associated with each of these highlight areas. An estimate of the image spread for each highlighted area in a line in the case of one dimensional processing or in a sector, in the case of two-dimensional processing, is determined. The phase error is determined using phase gradient processing. The phase error is then removed from the uncorrected image and the process is iteratively performed to substantially eliminate phase errors which can degrade the image.

Modalities of Generalization Through Single Case Studies.

PubMed

Zittoun, Tania

2017-06-01

The value of case studies for theory building is still doubted in psychology. The paper argues for the importance of case studies and the possibility of generalizing from these for a specific sociocultural understanding of human development. The paper first clarifies the notion of abduction within case studies, drawing on pragmatists James and Peirce and expanding it with the work of Lewin, and argues that it is the core mechanism that allows generalization from case studies. The second section presents the possibility of generalizing from individual single case studies, for which not only the subjective perspective, but also the dynamics by which the social and cultural environment guide and enable the person's development, have to be accounted for. The third section elaborates the question of institutional case studies, where the challenge is to account both for institutional dynamics, and for persons' trajectories within; this is exemplified with an ongoing study on the process of obtaining citizenship in Switzerland. The paper briefly concludes by highlighting two possible implications of the paper, one concerning the process of theoretical reasoning, the other, the fact that sociocultural psychology could itself be seen as an institution in-the-making.

User and researcher collaborations in mental health in low and middle income countries: a case study of the EMPOWER project

PubMed Central

2014-01-01

Background Increasing recognition has been given to the interaction of users and researchers in shaping the perspective and practice of mental health care. However, there remains very little evidence exploring how this interaction works, particularly in low and middle income countries. The aim of this study was to explore experiences of how users and researchers worked together to communicate research, using a case study of the EMPOWER project. Methods The study followed a case-study approach. EMPOWER was a project that sought to strengthen the capacity of user organizations in India, Kenya, Nepal and Zambia by encouraging user-researcher collaborations to communicate research findings in the four countries. A qualitative research method was applied for this study, with semi-structured interviews conducted with seven people: two researchers, one communications developer, and four user group members (one from each of the four countries). Data were analyzed using thematic analysis. Results The findings indicated positive perceptions of the collaboration between researchers and users. Key themes were partnership and support, the value of the personal experience of users and their knowledge of the target audiences, and empowerment. Key challenges related to differences in levels of education and technical knowledge and the lack of payments to users. Conclusions This exploratory study provides insight to help understand collaborative processes for communicating mental health research. It highlights many positive outcomes from the EMPOWER collaboration but also highlights the need for more in-depth research on this issue. PMID:24423150

Enhancing the hermeneutic single-case efficacy design: Bridging the research-practice gap.

PubMed

Wall, Jessie M; Kwee, Janelle L; Hu, Monica; McDonald, Marvin J

2017-09-01

Systematic case study designs are emerging as alternative paradigm strategies for psychotherapy and social science research. Through enhanced sensitivity to context, these designs examine idiographic profiles of causal processes. We specifically advocate the use of the hermeneutic single-case efficacy design (HSCED). HSCED has recently been used to investigate the efficacy of an existing therapy with a new population (Observed and Experiential Integration for athlete performance barriers) and an emerging therapy (Lifespan Integration Therapy). We describe innovations in HSCED that were implemented for these studies. These developments include (a) integrating psychotherapists as case developers, (b) incorporating multiple cases in one investigation, and (c) tailoring the repertoire of assessment tools. These extensions strategically incorporated principles of contextual paradigms in HSCED, thus complementing single-case designs that neglect idiographic contexts. We discuss recommendations for using HSCED in practice-based research, highlighting its potential as a bridge to address the research-practice gap.

The Republic of Djibouti is an African country that exhibits one of the highest incidence rate of tuberculosis in the world. The aim of this study was to evaluate the prevalence of multidrug-resistant tuberculosis among new cases. We studied retrospectively every tuberculosis case diagnosed over a 12-month period in patients hospitalized at the French Military Hospital of Bouffard. During this period, 1,274 samples from 675 patients were tested. We isolated 266 mycobacteria corresponding to 180 cases of tuberculosis. Thirty-three were fully susceptible and 57% met the tuberculosis criteria, with 46% primary resistance. No extensively-drug-resistant tuberculosis was found. Our results highlight a major concern about the situation in this part of the world.

Different factors have been shown to influence the development of models of advanced nursing practice (ANP) in primary-care settings. Although ANP is being developed in hospitals in Hong Kong, China, it remains undeveloped in primary care and little is known about the factors determining the development of such a model. The aims of the present study were to investigate the contribution of different models of nursing practice to the care provided in primary-care settings in Hong Kong, and to examine the determinants influencing the development of a model of ANP in such settings. A multiple case study design was selected using both qualitative and quantitative methods of data collection. Sampling methods reflected the population groups and stage of the case study. Sampling included a total population of 41 nurses from whom a secondary volunteer sample was drawn for face-to-face interviews. In each case study, a convenience sample of 70 patients were recruited, from whom 10 were selected purposively for a semi-structured telephone interview. An opportunistic sample of healthcare professionals was also selected. The within-case and cross-case analysis demonstrated four major determinants influencing the development of ANP: (1) current models of nursing practice; (2) the use of skills mix; (3) the perceived contribution of ANP to patient care; and (4) patients' expectations of care. The level of autonomy of individual nurses was considered particularly important. These determinants were used to develop a model of ANP for a primary-care setting. In conclusion, although the findings highlight the complexity determining the development and implementation of ANP in primary care, the proposed model suggests that definitions of advanced practice are appropriate to a range of practice models and cultural settings. However, the findings highlight the importance of assessing the effectiveness of such models in terms of cost and long-term patient outcomes.

Medical technologies: flows, frictions and new socialities

PubMed Central

Hardon, Anita; Moyer, Eileen

2014-01-01

While social scientists often highlight the way medical technologies mediate biomedical hegemony, this special issue focuses on the creative and often unexpected ways in which medical technologies are appropriated by diverse actors in homes, clinics and communities. The authors highlight key insights from twelve ethnographic case studies conducted in North and South America, Western Europe, Sub-Saharan Africa and Southeast Asia. The case studies focus on, among other issues, how sperm donors in Denmark, despite being subjugated to medical surveillance, experience the act of donating sperm as liberating; how sex workers in Indonesia turn to psychoactive painkillers to feel confident when approaching clients; why some anorexic patients in the United States resist prescribed antidepressant drugs; and how adolescent sex education workshops in Ecuador are appropriated by mothers to monitor their daughters and shame their ‘lying husbands’. Hardon and Moyer conclude that studies of medical technology need to be sensitive to the micro-dynamics of power, the specificities of local markets in which medical technologies generate value, the social and intergenerational relations in which they are embedded, and their intersections with class hierarchies.

2016-11-21

Spinal accessory nerve (SAN) injury can be an overlooked cause of scapular winging and shoulder dysfunction. The most common etiology is iatrogenic injury following surgical procedures at the posterior triangle of the neck. We present three cases of isolated injury to the SAN following trauma. To improve detection of SAN injuries through highlighting the clinical presentation, diagnosis and treatment via three cases in which the injuries were initially missed. Clinical case series and narrative review. Three (3) patients were evaluated by history, physical exam and electrodiagnostic study (EMG). Clinical symptoms included, a painful, droopy shoulder and difficulties with overhead activities. Clinical signs included the observation of scapular winging, and focal atrophy of the trapezius and in some cases the sternocleidomastoid (SCM). Novel clinical signs such as the active elevation lag sign and triangle sign were also helpful clinically to highlight the SAN as the site of pathology. EMG revealed denervation and reduced motor unit recruitment in the trapezius and SCM. Early detection of SAN injuries can be improved through appropriate clinical suspicion, a detailed history and careful physical exam. EMG testing can help guide prognosis, direct conservative and surgical treatment, and reduce patient morbidity.

Nodal marginal zone lymphoma (NMZL) represents a rare and heterogeneous group that lacks markers specific for the diagnosis. We evaluated morphologic and immunoarchitectural features of 51 NMZLs, and the following immunostains were performed: CD20, CD21, CD23, CD5, CD3, CD43, CD10, Ki-67, BCL1, BCL2, BCL6, HGAL, and LMO2. Four immunoarchitectural patterns were evident: diffuse (38 [75%]), well-formed nodular/follicular (5 [10%]), interfollicular (7 [14%]), and perifollicular (1 [2%]). Additional features included a monocytoid component (36 [71%]), admixed large cells (20 [39%]), plasma cells (24 [47%]), compartmentalizing stromal sclerosis (13 [25%]), and prominent blood vessel sclerosis (10 [20%]). CD21 highlighted disrupted follicular dendritic cell meshwork in 35 (71%) of 49 cases, and CD43 coexpression was present in 10 (24%) of 42 cases. A panel of germinal center-associated markers was helpful in eliminating cases of diffuse follicle center lymphoma. Our results highlight the histologic and immunoarchitectural spectrum of NMZL and the usefulness of immunohistochemical analysis for CD43, CD23, CD21, BCL6, HGAL, and LMO2 in the diagnosis of NMZL.

Bioethics education often includes the study of short stories, novels, plays, and films, because such materials present case examples that can highlight relevant issues and questions especially vividly for a wide range of students. In addition, creative writing is widely used in the education of health professional students and in continuing education settings for health professionals. There are very few academic or professional disciplines that do not use case studies, but the case study in dialogic form has not been standard practice for thousands of years. Dramatic arts casuistry-the creation and performance of short case studies designed specifically to raise bioethics issues for discussion-represents an application of literature and the medical humanities that is both unique and uniquely valuable. This essay describes the development and history of a course that has been successfully taught to medical students and graduate bioethics students, in which the class researches, writes, and performs a case study designed to elicit reflection and discussion about a topic and set of bioethics issues of current interest to both academic and general audiences. The model is also suited to the presentation and discussion of existing case studies, both live and via on-demand audio.

2017-11-01

We aim to highlight the importance of using a process-level view in analyzing distributed healthcare tasks through a case study analysis of medication management (MM). MM during older adults' hospital-to-skilled-home-healthcare (SHHC) transitions is a healthcare process with tasks distributed across people, organizations, and time. MM has typically been studied at the task level, but a process-level is needed to fully understand and improve MM during transitions. A process-level view allows for a broader investigation of how tasks are distributed throughout the work system through an investigation of interactions and the resultant emergent properties. We studied MM during older adults' hospital-to-SHHC transitions through interviews and observations with 60 older adults, their 33 caregivers, and 79 SHHC providers at 5 sites associated with 3 SHHC agencies. Study findings identified key cross-system characteristics not observable at the task-level: (1) identification of emergent properties (e.g., role ambiguity, loosely-coupled teams performing MM) and associated barriers; and (2) examination of barrier propagation across system boundaries. Findings highlight the importance of a process-level view of healthcare delivery occurring across system boundaries. Copyright © 2017 Elsevier Ltd. All rights reserved.

PubMed

Nathan, Deeepa; Shukla, Lekhansh; Kandasamy, Arun; Benegal, Vivek

2016-06-01

Background Problematic Internet use (PIU) is an emerging entity with varied contents. Behavioral addictions have high comorbidity of attention deficit hyperactivity disorder and obsessive-compulsive spectrum disorders. Social networking site (SNS) addiction and role playing game (RPG) addiction are traditionally studied as separate entities. We present a case with excessive Internet use, with a particular focus on phenomenology and psychiatric comorbidities. Case presentation Fifteen-year-old girl with childhood onset attention deficit disorder, obsessive-compulsive disorder, adolescent onset trichotillomania, and disturbed family environment presented with excessive Facebook use. Main online activity was creating profiles in names of mainstream fictional characters and assuming their identity (background, linguistic attributes, etc.). This was a group activity with significant socialization in the virtual world. Craving, salience, withdrawal, mood modification, and conflict were clearly elucidated and significant social and occupational dysfunction was evident. Discussion This case highlights various vulnerability and sociofamilial factors contributing to behavioral addiction. It also highlights the presence of untreated comorbidities in such cases. The difference from contemporary RPGs and uniqueness of role playing on SNS is discussed. SNS role playing as a separate genre of PIU and its potential to reach epidemic proportions are discussed. Conclusions Individuals with temperamental vulnerability are likely to develop behavioral addictions. Identification and management of comorbid conditions are important. The content of PIU continues to evolve and needs further study.

Sowash, Madeleine G.; Uhlemann, Anne-Catrin

2014-01-01

Over the past decade, the emergence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has changed the landscape of S. aureus infections around the globe. Initially recognized for its ability to cause disease in young and healthy individuals without healthcare exposures as well as for its distinct genotype and phenotype, this original description no longer fully encompasses the diversity of CA-MRSA as it continues to expand its niche. Using four case studies, we highlight a wide range of the clinical presentations and challenges of CA-MRSA. Based on these cases we further explore the globally polygenetic background of CA-MRSA with a special emphasis on generally less characterized populations. PMID:24085688

Two interesting cases highlighting an oblivious specialty of psychoneuroendocrinology.

PubMed

Hari Kumar, K V S; Dhull, Pawan; Somasekharan, Manoj; Seshadri, K

2012-01-01

Psychoneuroendocrinology deals with the overlap disorders pertaining to three different specialties. Awareness about the somatic manifestations of psychiatric diseases and vice versa is a must for all the clinicians. The knowledge of this interlinked specialty is essential because of the obscure presentation of certain disorders. Our first case was treated as depressive disorder, whereas the diagnosis was hypogonadism with empty sella. Our second patient was managed as schizophrenia and the evaluation revealed bilateral basal ganglia calcification and a diagnosis of Fahr's disease. We report these cases for their unusual presentation and to highlight the importance of this emerging specialty.

Use of Comparative Case Study Methodology for US Public Health Policy Analysis: A Review.

PubMed

Dinour, Lauren M; Kwan, Amy; Freudenberg, Nicholas

There is growing recognition that policies influence population health, highlighting the need for evidence to inform future policy development and reform. This review describes how comparative case study methodology has been applied to public health policy research and discusses the methodology's potential to contribute to this evidence. English-language, peer-reviewed articles published between 1995 and 2012 were sought from 4 databases. Articles were included if they described comparative case studies addressing US public health policy. Two researchers independently assessed the 20 articles meeting review criteria. Case-related characteristics and research design tactics utilized to minimize threats to reliability and validity, such as the use of multiple sources of evidence and a case study protocol, were extracted from each article. Although comparative case study methodology has been used to analyze a range of public health policies at all stages and levels, articles reported an average use of only 3.65 (out of 10) research design tactics. By expanding the use of accepted research design tactics, public health policy researchers can contribute to expanding the evidence needed to advance health-promoting policies.

The distribution and redistribution of fentanyl & norfentanyl in post mortem samples.

PubMed

Chatterton, C N; Scott-Ham, M

2018-03-01

This article compares 249 post mortem case reports that were positive for fentanyl/norfentanyl. All the cases were submitted to, and analyzed by, the toxicology department of the Office of the Chief Medical Examiner, Edmonton, Alberta, Canada. This study highlights the varied distribution of fentanyl in the body after death as a result of misadventure, i.e., these are accidental drug overdose cases as opposed to a study of analytical data resulting from fentanyl use/administration in a clinical environment and/or death as a result of suicide. Post mortem samples were collected from more than one anatomical site and analyzed for fentanyl and norfentanyl using liquid chromatography-tandem mass spectrometry. Ante-mortem samples were available in 4 of these cases and were also analyzed. Post mortem mean blood fentanyl concentrations were found to be 13.2ng/mL (femoral), 19.1ng/mL (iliac) and 42.0ng/mL (subclavian). For norfentanyl the mean concentrations were 4.6ng/mL (femoral), 4.6ng/mL (iliac) and 7.4ng/mL (subclavian). Mean vitreous fentanyl and norfentanyl concentrations were 10.8ng/mL and 3.5ng/mL respectively. Mean liver fentanyl and norfentanyl concentrations were found to be 185.5ng/g and 18.8ng/g respectively. This study demonstrates the importance of multi-site sample collection and subsequent analysis for a thorough post mortem toxicological investigation. The study also highlights the risks and limitations associated with the interpretation of post mortem analytical results concerning fentanyl. Copyright © 2018 Elsevier B.V. All rights reserved.

Case-Control Studies of Sporadic Enteric Infections: A Review and Discussion of Studies Conducted Internationally from 1990 to 2009

2015-01-01

Epidemiologists have used case-control studies to investigate enteric disease outbreaks for many decades. Increasingly, case-control studies are also used to investigate risk factors for sporadic (not outbreak-associated) disease. While the same basic approach is used, there are important differences between outbreak and sporadic disease settings that need to be considered in the design and implementation of the case-control study for sporadic disease. Through the International Collaboration on Enteric Disease “Burden of Illness” Studies (the International Collaboration), we reviewed 79 case-control studies of sporadic enteric infections caused by nine pathogens that were conducted in 22 countries and published from 1990 through to 2009. We highlight important methodological and study design issues (including case definition, control selection, and exposure assessment) and discuss how approaches to the study of sporadic enteric disease have changed over the last 20 years (e.g., making use of more sensitive case definitions, databases of controls, and computer-assisted interviewing). As our understanding of sporadic enteric infections grows, methods and topics for case-control studies are expected to continue to evolve; for example, advances in understanding of the role of immunity can be used to improve control selection, the apparent protective effects of certain foods can be further explored, and case-control studies can be used to provide population-based measures of the burden of disease.

Lesbians still face job discrimination.

PubMed

Ryniker, Margaret R

2008-01-01

This article examines continued discrimination against lesbians in the workplace. A number of cases from various jurisdictions in the United States are highlighted. The paper studies two common forms of discrimination: denial of employment benefits to same sex partners, and sexual harassment. On the first front, the case law suggests that health insurance coverage for one's partner is becoming the norm. On the question of sexual harassment in the workplace, the case law did not provide protection for lesbians. Finally, U.S. employment policies related to sexual orientation are contrasted with those in Israel, which provides much greater protection from discrimination.

Costa, Carolina; Araujo, Alberto; Brasil, Marco; Cruz, Marcelo

2015-01-01

Alert for the risk of oral bupropion addiction in patients with cocaine dependence. Single-case study. After a period of cocaine and alcohol abstinence, a 42-year-old patient started taking oral bupropion to relieve the symptoms of cocaine craving. He increased the bupropion dose up to 2250 mg/d without seizures. This case highlights the possibility of oral bupropion addiction after cocaine dependence. To our knowledge, it is the first case in the literature and emphasizes the risk of bupropion's misuse. Therefore, physicians should carefully examine the patient's profile before prescribing it, as well as follow appropriate measures.

Li, Jie; Kolivras, Korine N.; Hong, Yili; Duan, Yuanyuan; Seukep, Sara E.; Prisley, Stephen P.; Campbell, James B.; Gaines, David N.

2014-01-01

The emergence of infectious diseases over the past several decades has highlighted the need to better understand epidemics and prepare for the spread of diseases into new areas. As these diseases expand their geographic range, cases are recorded at different geographic locations over time, making the analysis and prediction of this expansion complicated. In this study, we analyze spatial patterns of the disease using a statistical smoothing analysis based on areal (census tract level) count data of Lyme disease cases in Virginia from 1998 to 2011. We also use space and space–time scan statistics to reveal the presence of clusters in the spatial and spatiotemporal distribution of Lyme disease. Our results confirm and quantify the continued emergence of Lyme disease to the south and west in states along the eastern coast of the United States. The results also highlight areas where education and surveillance needs are highest. PMID:25331806

The Dynamical Core Model Intercomparison Project (DCMIP-2016): Results of the Supercell Test Case

NASA Astrophysics Data System (ADS)

Zarzycki, C. M.; Reed, K. A.; Jablonowski, C.; Ullrich, P. A.; Kent, J.; Lauritzen, P. H.; Nair, R. D.

2016-12-01

The 2016 Dynamical Core Model Intercomparison Project (DCMIP-2016) assesses the modeling techniques for global climate and weather models and was recently held at the National Center for Atmospheric Research (NCAR) in conjunction with a two-week summer school. Over 12 different international modeling groups participated in DCMIP-2016 and focused on the evaluation of the newest non-hydrostatic dynamical core designs for future high-resolution weather and climate models. The paper highlights the results of the third DCMIP-2016 test case, which is an idealized supercell storm on a reduced-radius Earth. The supercell storm test permits the study of a non-hydrostatic moist flow field with strong vertical velocities and associated precipitation. This test assesses the behavior of global modeling systems at extremely high spatial resolution and is used in the development of next-generation numerical weather prediction capabilities. In this regime the effective grid spacing is very similar to the horizontal scale of convective plumes, emphasizing resolved non-hydrostatic dynamics. The supercell test case sheds light on the physics-dynamics interplay and highlights the impact of diffusion on model solutions.

[The impact of AIDS on the organizational development of nongovernmental organizations: a case study on Casa de Assistência Filadélfia].

PubMed

Bochio, Ieda Maria Siebra; Fortes, Paulo Antonio de Carvalho

2008-11-01

AIDS has been a unique event due not only to its devastating effects, but also to the ways in which it has stimulated solidarity and mobilization of society in the defense of the rights of persons living with HIV/AIDS and their families, friends, and contacts. Beginning as initiatives to ensure dignity in death, AIDS NGOs have undergone structural changes to respond to the demands raised by the epidemic. The current study describes the history of the Brazilian AIDS NGO "Casa de Assistência Filadélfia" in relation to the evolution of the AIDS epidemic, highlighting the issue of organizational development. A qualitative case study methodology was used, and the data were collected from document analysis and semi-structured interviews with key informants identified by the organization. Data analysis was based on the theoretical premises of organizational development and shows how the organization made the transition from the pioneering phase marked by improvisation and expanded to a phase of regulation until reaching flexibility and innovation by diversifying its projects. The study highlights the importance of organizational development as an essential element in building healthy, agile organizations in the response to their demands.

Given the sparse information on the burden of influenza in Lebanon, the Ministry of Public Health established a sentinel surveillance for severe acute respiratory infections (SARI) to identify the attribution of influenza to reported cases. We aim to highlight the proportion of influenza-associated SARI from September 1st, 2015 to August 31st, 2016 in 2 Lebanese hospitals. The study was conducted in 2 sentinel sites located in Beirut suburbs and southern province of Lebanon. WHO's 2011 standardized SARI case definition was used. Data from September 1, 2015 to August 31, 2016 were reviewed, and all-cause hospital admission numbers were obtained. Nasopharyngeal swabs were collected and tested by RT-PCR. Descriptive and bivariate analyses were conducted using STATA 13. The 2 sentinel sites reported 746 SARI cases during the studied time frame: 467 from the southern province site and 279 from the Beirut suburbs site. SARI reports peaked between January and March 2016. All, except 4, cases were sampled, and a co-dominance of influenza B (43%) and influenza A (H1N1) (41%) was evident. A high proportion of cases was reported in children <2 years 274 (37%). The proportional contribution of influenza-associated SARI to all-cause hospital admissions was high in children <2 years in the south (4.5% [95% CI: 3.1-6.5]) and in children <5 years in Beirut (0.7% [95% CI: 0.6-0.8]). This is the first study to highlight the proportion of influenza-associated SARI in 2 hospitals in Lebanon. The findings will be beneficial for supporting respiratory prevention and immunization program policies. © 2017 The Authors.

Using national surveillance data for 120,111 human anthrax cases recorded during 1955−2014, we analyzed the temporal, seasonal, geographic, and demographic distribution of this disease in China. After 1978, incidence decreased until 2013, when it reached a low of 0.014 cases/100,000 population. The case-fatality rate, cumulatively 3.6% during the study period, has also decreased since 1990. Cases occurred throughout the year, peaking in August. Geographic distribution decreased overall from west to east, but the cumulative number of affected counties increased during 2005−2014. The disease has shifted from industrial to agricultural workers; 86.7% of cases occurred in farmers and herdsmen. Most (97.7%) reported cases were the cutaneous form. Although progress has been made in reducing incidence, this study highlights areas that need improvement. Adequate laboratory diagnosis is lacking; only 7.6% of cases received laboratory confirmation. Geographic expansion of the disease indicates that livestock control programs will be essential in eradicating anthrax. PMID:27983489

Gastrointestinal helminthiasis in developing countries contributes to malnutrition and anemia. Diagnosis and treatment of helminthiasis, especially with low worm load is an unmet public health need in such settings. The infection may sometimes become manifest when a second pathology leads to purgation of the gastrointestinal tract. Two cases of helminthiasis are presented in which the infections only became amenable to diagnosis due to acute diarrhoea caused by giardiasis and lactulose administration. In the first case, acute giardiasis revealed Ascaris lumbricoides infestation, and in the second case primary helminthiasis (strongyloidiasis) was revealed by lactulose, and also led to Vibrio cholera bacteremia. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes.

As nebulous as the details of the German diagnosis-oriented case reimbursement rate (G-DRGs) might be, one thing is obvious: rapid and accurate diagnostics will be vital in future to the reimbursement of standard cases that reflect the actual outlay. The laboratory that up to now has always been categorized as a potential for savings, now becomes a source of revenue for hospitals. A study initiated by the VDGH provides evidence for this (Clinical Laboratory 2002, 48, 327).

2011-08-01

Odorous vaginal discharge is a common presentation to general practitioners, and a frequent presentation for bacterial infections and sexually transmissible diseases. Busy GPs may be tempted to make a diagnosis from the clinical history and symptoms, and prescribe antibiotics as a first line treatment. This case highlights an unusual cause of persistent odorous vaginal discharge. If a thorough examination had not been conducted, the cause would have been overlooked, first line antibiotics would most likely have been ineffective, and potentially life threatening consequences may have occurred.

Child sexual abuse (CSA) is a global problem that has significant consequences for public health; it has been a prominent topic of public concern for more than a decade, but many basic facts about the problem remain unclear or in dispute. We conducted a study of 311 cases of CSA in order to highlight the epidemiological features and negative impact on victims' well-being and to emphasize the need for a multidisciplinary approach to the primary prevention and management of CSA. We noted an increase in cases number with male predominance. Most of our patients came from lower socioeconomic classes. The perpetrators were male in 100% of cases; acquaintances in 70% of cases and family members in 22 cases. Physical examination were normal in 61% of cases, however, a range of psychological and physical effects were identified with dramatic health consequences: three cases of attempted suicide, five pregnancies and one case of HIV virus infection.

Many biological, hydrological, and geological processes are interactively linked in ecosystems. These ecological phenomena normally vary within bounded ranges, but rapid, nonlinear changes to markedly different conditions can be triggered by even small differences if threshold values are exceeded. Intrinsic and extrinsic ecological thresholds can lead to effects that cascade among systems, precluding accurate modeling and prediction of system response to climate change. Ten case studies from North America illustrate how changes in climate can lead to rapid, threshold-type responses within ecological communities; the case studies also highlight the role of human activities that alter the rate or direction of system response to climate change. Understanding and anticipating nonlinear dynamics are important aspects of adaptation planning since responses of biological resources to changes in the physical climate system are not necessarily proportional and sometimes, as in the case of complex ecological systems, inherently nonlinear.

This article will focus on a hypothetical case study to highlight comprehensive assessment and treatment for adolescent children who stutter. Assessment and treatment are laid out with a literature review utilizing the components of the International Classification of Functioning, Disability and Health model. Specific assessment and treatment strategies and approaches are discussed. Using the International Classification of Functioning, Disability and Health model can help guide clinicians through the assessment and treatment process to ensure that all areas of stuttering are considered. Comprehensive assessment and treatment helps clinicians address all relevant elements of a stuttering disorder, rather than focusing exclusively on reducing speech disruptions.

The importance of the verbal shift handover report: a multi-site case study.

PubMed

Randell, Rebecca; Wilson, Stephanie; Woodward, Peter

2011-11-01

Shift handover is seen as a key tool in ensuring continuity of care yet a number of studies have highlighted the role of shift handovers in adverse events. This, combined with the increased frequency of shift handovers, has led to interest in providing technological support for handover to enhance safety. The aim of this paper is to describe current practices for the conduct of shift handovers and to use this as a basis for considering the role that technology could play in supporting handover. A multi-site case study of handover was conducted. Data included observations of 15 medical shift handovers and 33 nursing shift handovers across three case sites. The findings highlight the way in which the verbal shift handover report is practically focused, displaying the healthcare professional's ability to know what information is required and where further explanation is needed. As well as supporting teaching and team cohesion, shift handover can provide an opportunity to reflect on the previous shift and for discussion with patients and their families. The benefits provided by a face to face handover suggest that technology should focus on supporting rather than replacing the verbal shift handover report, providing a flexible solution that allows handover participants to gather more information as it is required.

Faith without answers: the use of religion among cold case homicide survivors.

PubMed

Wellman, Ashley R P

2014-01-01

Through data gathered from interviews with cold case homicide survivors, this article reveals the important role of religion and faith in the aftermath of an unsolved murder. Using qualitative methodology, the author highlights the lived experiences and personal journeys of cold case homicide surviving family members, who are often a forgotten and an overlooked segment of victims. Qualitative data suggests that these cold case homicide survivors found religion to be critical in the aftermath of their loved one's murder. Specifically, survivors indicated their faith was fundamental in coping with the homicide and provided hope for anticipating a resolution in their cases. From these intimate, personal survivor accounts, scholars and practitioners can begin to develop future research and programs that are specifically designed to highlight the role of religion in moving forward after an unsolved murder.

Landsat and agriculture—Case studies on the uses and benefits of Landsat imagery in agricultural monitoring and production

USGS Publications Warehouse

Leslie, Colin R.; Serbina, Larisa O.; Miller, Holly M.

2017-03-29

Executive SummaryThe use of Landsat satellite imagery for global agricultural monitoring began almost immediately after the launch of Landsat 1 in 1972, making agricultural monitoring one of the longest-standing operational applications for the Landsat program. More recently, Landsat imagery has been used in domestic agricultural applications as an input for field-level production management. The enactment of the U.S. Geological Survey’s free and open data policy in 2008 and the launch of Landsat 8 in 2013 have both influenced agricultural applications. This report presents two primary sets of case studies on the applications and benefits of Landsat imagery use in agriculture. The first set examines several operational applications within the U.S. Department of Agriculture (USDA) and the second focuses on private sector applications for agronomic management.  Information on the USDA applications is provided in the U.S. Department of Agriculture Uses of Landsat Imagery for Global and Domestic Agricultural Monitoring section of the report in the following subsections:Estimating Crop Production.—Provides an overview of how Landsat satellite imagery is used to estimate crop production, including the spectral bands most frequently utilized in this application.Monitoring Consumptive Water Use.—Highlights the role of Landsat imagery in monitoring consumptive water use for agricultural production. Globally, a significant amount of agricultural production relies on irrigation, so monitoring water resources is a critical component of agricultural monitoring. National Agricultural Statistics Service—Cropland Data Layer.—Highlights the use of Landsat imagery in developing the annual Cropland Data Layer, a crop-specific land cover classification product that provides information on more than 100 crop categories grown in the United States. Foreign Agricultural Service—Global Agricultural Monitoring.—Highlights Landsat’s role in monitoring global agricultural production. The USDA has been using Landsat imagery to monitor global agricultural production since the launch of Landsat 1 in 1972. Landsat imagery provides objective, global input for a number of USDA agricultural programs and plays an important role in economic and food security forecasting.U.S. Department of Agriculture—Satellite Imagery Archive.—Highlights a number of the experiences of the USDA in acquiring, sharing, and managing moderate resolution imagery to support the diversity of USDA operational programs. Private sector applications using Landsat imagery for agricultural management are discussed in the Landsat Imagery Use and Benefits in Field-Level Agricultural Production Management section of the report in the following subsections:Field-Level Management.—Provides an introduction to what field-level production management is and how it can be applied to agricultural management. This section explores the concept of zone mapping and how Landsat imagery can be used to identify different conditions within a field. The section also provides a case study of zone-mapping software, developed by GK Technology, Inc., that is used by numerous agricultural consultants.Putting Zone Maps to Work.—Highlights several case studies of private agricultural consultants who have been using Landsat imagery to develop zone maps for farmers. Landsat imagery is helping consultants and farmers optimize agricultural inputs, including fertilizer and seed, which leads to higher yield and economic return for the farmer.Increasing Yield.—Highlights the primary benefit of zone mapping using Landsat imagery. Using 5-year market average prices for a number of commodities, this section provides examples of how yield increases translate into higher returns for farmers.

Heterogeneous Risk Perceptions: The Case of Poultry Meat Purchase Intentions in Finland

PubMed Central

Heikkilä, Jaakko; Pouta, Eija; Forsman-Hugg, Sari; Mäkelä, Johanna

2013-01-01

This study focused on the heterogeneity of consumer reactions, measured through poultry meat purchase intentions, when facing three cases of risk. The heterogeneity was analysed by latent class logistic regression that included all three risk cases. Approximately 60% of the respondents belonged to the group of production risk avoiders, in which the intention to purchase risk food was significantly lower than in the second group of risk neutrals. In addition to socio-demographic variables, the purchase intentions were statistically associated with several attitude-based variables. We highlighted some policy implications of the heterogeneity. Overall, the study demonstrated that risk matters to consumers, not all risk is equal, and consumer types react somewhat differently to different types of risk. PMID:24157513

Using Family-Based Exposure With Response Prevention to Treat Obsessive-Compulsive Disorder in Young Children: A Case Study.

PubMed

Herren, Jenny; Freeman, Jennifer; Garcia, Abbe

2016-11-01

Cognitive-behavioral therapy (CBT) using exposure with response prevention (ERP) is the treatment of choice for obsessive-compulsive disorder (OCD); however, developmental modifications should be considered when treating young children. This article presents a case study illustrating family-based CBT using ERP with a 7-year-old boy. The delivery of ERP for this case was guided by 3 main principles: (a) family involvement with a focus on reducing family accommodation, (b) understanding the functional relation between the client's obsessions and compulsions, and (c) creating conditions to facilitate habituation during exposure. Outcomes for this case indicate significant improvement in functioning and OCD symptoms. Results highlight the importance of family involvement and the applicability of using a function-based habituation framework when delivering ERP to this unique population. © 2016 Wiley Periodicals, Inc.

Gastric heterotopia of the intestinal tract can have a diverse clinicopathologic presentation, resulting in a diagnostic dilemma. We present a series of four cases, two male and two female patients with age range of 31-82 years, found in the duodenum, jejunum, and transverse colon. The most common and rather unusual clinical presentation was iron deficiency anemia, seen in three cases, while one patient presented with abdominal pain. Endoscopically, two cases were visualized as pedunculated polyps and two as sessile/plaque-like lesions. Polypectomy was performed in three patients, and one patient underwent biopsy followed by resection. Two cases showed oxyntic-type epithelium, and two cases exhibited pyloric-type gastric epithelium. Three patients were relieved of their presenting symptoms after therapeutic procedures with no evidence of recurrence noted on follow-up. Follow-up was not available on one patient. This case series highlights a diverse clinicopathologic spectrum of gastric heterotopia. Accurate diagnosis is essential for proper management. Copyright © 2018. Published by Elsevier Inc.

2008-07-01

In Tanzania sleeping sickness presents a serious threat to human health with a country-wide average of 400 cases reported annually. Both wild and domestic animals have been found to play a significant role in the epidemiology of sleeping sickness. Serengeti National Park in northern Tanzania, has experienced a number of sleeping sickness epidemics since 1922. The epidemics were associated with abundant game animals in the areas and Glossina swynnertoni was incriminated as the main vector. However since 2001 there has been no case of sleeping sickness reported from the park. This case report highlights on the possibility of resurgence and challenges in the diagnosis and management of sleeping sickness in Serengeti. A 38 years old Tanzanian man working in the Serengeti National Park who had experienced various tsetse bites was presented with a febrile condition and history of unsuccessful case management at different health facilities. Blood and cerebrospinal fluid (CSF) samples were examined for the presence oftrypanosomes using wet film, Field's stain and concentration techniques. Typanosoma brucei rhodesiense were detected in both the blood and CSF samples. The patient was treated successfully with melarsoprol. The results of this case study highlight the possibility of resurgence of sleeping sickness in the park hence calls for the need to create more awareness among the community and clinicians. There is need for early reporting to health facility and strengthening the diagnostic capacity of healthcare facilities in and around national parks endemic for sleeping sickness.

The impact of hospitalisation on a visiting family member: A case study and discussion.

PubMed

Rückholdt, Monica; Tofler, Geoffrey H; Buckley, Thomas

2017-05-01

Evidence suggests that when an immediate family member of a spouse is hospitalised, the partner's risk of death significantly increases. Hospitalisation can represent a time of great vulnerability and imposed stress for both the patient and their family members. Family members have been reported to give priority to the welfare of their ill relative and in their heightened emotional state, often adversely put their own health at risk. The paper presents a case study highlighting how an intensive care hospitalisation and discharge to rehabilitation experience for a patient's mother triggered an episode of myocardial infarction for her adult son. Discussion focuses on the caregiving burden and potential mechanisms for how hospitalisation may contribute to the health risk of immediate family members of hospitalised patients. Discussion also highlights the importance of family members receiving clear, continuous and consistent information from a limited number of clinicians to help reduce the stress associated with caregiving during acute hospitalisation.

Specialty hospitals emulating focused factories: a case study.

PubMed

Kumar, Sameer

2010-01-01

For 15 years general hospital managers faced new competition from for-profit specialty hospitals that operate on a "focused factory" model, which threaten to siphon-off the most profitable patients. This paper aims to discuss North American specialty hospitals and to review rising costs impact on general hospital operations. The focus is to discover whether specialty hospitals are more efficient than general hospitals; if so, how significant is the difference and also what can general hospitals do in light of the rising specialty hospitals. The case study involves stochastic frontier regression analysis using Cobb-Douglas and Translog cost functions to compare Minnesota general and specialty hospital efficiency. Analysis is based on data from 117 general and 19 specialty hospitals. The results suggest that specialty hospitals are significantly more efficient than general hospitals. Overall, general hospitals were found to be more than twice as inefficient compared with specialty hospitals in the sample. Some cost-cutting factors highlighted can be implemented to trim rising costs. The case study highlights some managerial levers that general hospital operational managers might use to control rising costs. This also helps them compete with specialty hospitals by reducing overheads and other major costs. The study is based on empirical modeling for an important healthcare operational challenge and provides additional in-depth information that has health policy implications. The analysis and findings enable healthcare managers to guide their institutions in a new direction during a time of change within the industry.

2015-03-01

Clinical commissioning groups (CCGs) are required to demonstrate meaningful patient and public engagement and involvement (PPEI). Recent health service reforms have included financial incentives for general practices to develop patient reference groups (PRGs). To explore the impact of the patient participation direct enhanced service (DES) on development of PRGs, the influence of PRGs on decision making within general practice, and their interface with CCGs. A mixed-methods approach within three case study sites in England. Three case study sites were tracked for 18 months as part of an evaluation of PPEI in commissioning. A sub-study focused on PRGs utilising documentary and web-based analysis; results were mapped against findings of the main study. Evidence highlighted variations in the establishment of PRGs, with the number of active PRGs via practice websites ranging from 27% to 93%. Such groups were given a number of descriptions such as patient reference groups, patient participation groups, and patient forums. Data analysis highlighted that the mode of operation varied between virtual and tangible groups and whether they were GP- or patient-led, such analysis enabled the construction of a typology of PRGs. Evidence reviewed suggested that groups functioned within parameters of the DES with activities limited to practice level. Data analysis highlighted a lack of strategic vision in relation to such groups, particularly their role within an overall patient and PPEI framework). Findings identified diversity in the operationalisation of PRGs. Their development does not appear linked to a strategic vision or overall PPEI framework. Although local pragmatic issues are important to patients, GPs must ensure that PRGs develop strategic direction if health reforms are to be addressed. © British Journal of General Practice 2015.

MELAS syndrome presenting as an acute surgical abdomen.

Dindyal, S; Mistry, K; Angamuthu, N; Smith, G; Hilton, D; Arumugam, P; Mathew, J

2014-01-01

MELAS (mitochondrial cytopathy, encephalomyopathy, lactic acidosis and stroke-like episodes) is a syndrome in which signs and symptoms of gastrointestinal disease are uncommon if not rare. We describe the case of a young woman who presented as an acute surgical emergency, diagnosed as toxic megacolon necessitating an emergency total colectomy. MELAS syndrome was suspected postoperatively owing to persistent lactic acidosis and neurological symptoms. The diagnosis was later confirmed with histological and genetic studies. This case highlights the difficulties in diagnosing MELAS because of its unpredictable presentation and clinical course. We therefore recommend a high index of suspicion in cases of an acute surgical abdomen with additional neurological features or raised lactate.

Acute generalized exanthematous pustulosis (AGEP) is an uncommon pustular eruption characterized by small nonfollicular pustules on an erythematous background, sometimes associated with fever and neutrophilia. Over 90% of cases are drug-induced; however, it can be caused in rare cases by other agents. We report two cases of AGEP secondary to ingestion of Pistacia lentiscus essential oil, the first two such cases to our knowledge. The cutaneous morphology, disease course and histological findings were consistent with a definite diagnosis of AGEP, based on the criteria of the EuroSCAR study group. These two cases highlight the need to consider herbal extracts as a potential rare cause of AGEP and to ensure the safety of herbal medicines. © The Author(s).

To determine risk factors associated with the occurrence of sporadic cases of Salmonella enteritidis infections among children in France, we conducted a matched case-control study. Cases were identified between 1 March and 30 September 1995. One hundred and five pairs of cases and controls matched for age and place of residence were interviewed. In the 1-5 years age group, illness was associated with the consumption of raw eggs or undercooked egg-containing foods (OR 2.4, 95% CI 1.2-4.8). Storing eggs more than 2 weeks after purchase was associated with Salmonella enteritidis infection (OR 3.8, 95% CI 1.4-10.2), particularly during the summer period (OR 6.0, 95% CI 1.3-26.8). Cases were more likely to report a case of diarrhoea in the household 10-3 days before the onset of symptoms, particularly in the age group < or = 1 year (P = 0.01). This study confirms the link between eggs and the occurrence of sporadic cases of Salmonella enteritidis among children, highlights the potential role of prolonged egg storage and underlines the role of person-to-person transmission in infants.

Wells, Melissa; Mitchell, Kimberly J; Ji, Kai

2012-01-01

This exploratory analysis examines the role of the Internet in juvenile prostitution cases coming to the attention of law enforcement. The National Juvenile Prostitution Study (N-JPS) collected information from a national sample of law enforcement agencies about the characteristics of juvenile prostitution cases. In comparison to non-Internet juvenile prostitution cases, Internet juvenile prostitution cases involved younger juveniles and police were more likely to treat juveniles as victims rather than offenders. In addition, these cases were significantly more likely to involve a family or acquaintance exploiter. This analysis suggests that the role of the Internet may impact legal and social service response to juveniles involved in prostitution. In addition, it highlights the need for interventions that acknowledge the vulnerabilities of youth involved in this type of commercial sexual exploitation.

Helu, Moneer; Weiss, Brian

2017-01-01

The development of digital technologies for manufacturing has been challenged by the difficulty of navigating the breadth of new technologies available to industry. This difficulty is compounded by technologies developed without a good understanding of the capabilities and limitations of the manufacturing environment, especially within small-to-medium enterprises (SMEs). This paper describes industrial case studies conducted to identify the needs, priorities, and constraints of manufacturing SMEs in the areas of performance measurement, condition monitoring, diagnosis, and prognosis. These case studies focused on contract and original equipment manufacturers with less than 500 employees from several industrial sectors. Solution and equipment providers and National Institute of Standards and Technology (NIST) Hollings Manufacturing Extension Partnership (MEP) centers were also included. Each case study involved discussions with key shop-floor personnel as well as site visits with some participants. The case studies highlight SME's strong need for access to appropriate data to better understand and plan manufacturing operations. They also help define industrially-relevant use cases in several areas of manufacturing operations, including scheduling support, maintenance planning, resource budgeting, and workforce augmentation.

The genetic basis of sporadic colorectal cancer (CRC) is not well explained by known risk polymorphisms. Here we perform a meta-analysis of two genome-wide association studies in 2,627 cases and 3,797 controls of Japanese ancestry and 1,894 cases and 4,703 controls of African ancestry, to identify genetic variants that contribute to CRC susceptibility. We replicate genome-wide statistically significant associations (P < 5×10−8) in 16,823 cases and 18,211 controls of European ancestry. This study reveals a new pan-ethnic CRC risk locus at 10q25 (rs12241008, intronic to VTI1A; P=1.4×10−9), providing additional insight into the etiology of CRC and highlighting the value of association mapping in diverse populations.

HSPF Modeling for Compliance and Enforcement: An Urban Case Study

NASA Astrophysics Data System (ADS)

Marshalonis, D.

2017-12-01

Stormwater runoff is one of the most significant challenges to water quality facing surface waters globally. In the United States, the Environmental Protection Agency (EPA) regulates stormwater flows through its National Pollutant Discharge Elimination System (NPDES) program permits. When egregious violations occur, EPA may develop its case and prove those violations through the legal dispute process. However, evidence in stormwater-related cases is ephemeral, difficult to collect due to unpredictable weather dynamics, and there are usually no witnesses. The work presented here illustrates an approach EPA takes for certain wet weather cases: introduce results from hydrologic and hydraulic models as evidence to meet legal burden of proof standards. The challenges and opportunities of using models in stormwater discharge modeling are highlighted.

The clinical course was prolonged, with minimal spontaneous improvement at onset, and a period of fluctuating motor weakness and nasogastric feeding dependence afterward. Neurophysiologic studies produced normal results. Human botulism immune globulin was administered empirically on day 23 of presentation, with rapid full recovery. This case highlights the importance of pursuing diagnoses of infant botulism despite normal results of neurophysiologic testing and no history of honey-feeding. Our case also demonstrates a favorable response to human botulism immune globulin, despite the relatively late treatment.

Handa, Uma; Chhabra, Seema; Mohan, Harsh

2007-10-01

This study was undertaken to highlight the use of fine needle aspiration cytology (FNAC) to distinguish tumours metastatic to the breast from primary breast malignancies. A total of 1866 fine needle aspirates of the breast were performed during a period of 7 years. Three hundred and fourteen cases of breast malignancies were diagnosed and 5 (1.5%) out of these cases were metastatic in origin. The metastatic tumors included, 2 cases of malignant melanoma (chest wall and left arm), 1 case each of haematolymphoid malignancy, adenocarcinoma of the ovary, and squamous cell carcinoma (left leg). FNA diagnosis of metastasis to the breast is essential in order to avoid unnecessary mastectomy and to ensure appropriate chemotherapy and/or irradiation treatment.

Joint perceptual decision-making: a case study in explanatory pluralism

Traditionally different approaches to the study of cognition have been viewed as competing explanatory frameworks. An alternative view, explanatory pluralism, regards different approaches to the study of cognition as complementary ways of studying the same phenomenon, at specific temporal and spatial scales, using appropriate methodological tools. Explanatory pluralism has been often described abstractly, but has rarely been applied to concrete cases. We present a case study of explanatory pluralism. We discuss three separate ways of studying the same phenomenon: a perceptual decision-making task (Bahrami et al., 2010), where pairs of subjects share information to jointly individuate an oddball stimulus among a set of distractors. Each approach analyzed the same corpus but targeted different units of analysis at different levels of description: decision-making at the behavioral level, confidence sharing at the linguistic level, and acoustic energy at the physical level. We discuss the utility of explanatory pluralism for describing this complex, multiscale phenomenon, show ways in which this case study sheds new light on the concept of pluralism, and highlight good practices to critically assess and complement approaches.

2015-01-01

The purpose of the present study was to re-examine diagnostic data from a state-wide autism prevalence study (n = 489) conducted in the 1980s to investigate the impact of broader diagnostic criteria on autism spectrum disorder (ASD) case status. Sixty-four (59 %) of the 108 originally “Diagnosed Not Autistic” met the current ASD case definition. The average IQ estimate in the newly identified group (IQ = 35.58; SD = 23.01) was significantly lower than in the original group (IQ = 56.19 SD = 21.21; t = 5.75; p < .0001). Today’s diagnostic criteria applied to participants ascertained in the 1980s identified more cases of autism with intellectual disability. The current analysis puts this historic work into context and highlights differences in ascertainment between epidemiological studies performed decades ago and those of today. PMID:22696195

Geo-Distinctive Comorbidity Networks of Pediatric Asthma.

Shin, Eun Kyong; Shaban-Nejad, Arash

2018-01-01

Most pediatric asthma cases occur in complex interdependencies, exhibiting complex manifestation of multiple symptoms. Studying asthma comorbidities can help to better understand the etiology pathway of the disease. Albeit such relations of co-expressed symptoms and their interactions have been highlighted recently, empirical investigation has not been rigorously applied to pediatric asthma cases. In this study, we use computational network modeling and analysis to reveal the links and associations between commonly co-observed diseases/conditions with asthma among children in Memphis, Tennessee. We present a novel method for geo-parsed comorbidity network analysis to show the distinctive patterns of comorbidity networks in urban and suburban areas in Memphis.

Asperger's syndrome is an autistic spectrum disorder, which has engendered lesser attention in comparison to autism. Recent literature has focused on the involvement of cortical areas of the brain in this syndrome. We report a case of Asperger′s syndrome in which an extensive work-up, including neuropsychological, neurophysiological and neuroimaging procedures, were undertaken. The findings of the various investigative procedures are discussed and literature supporting the neurobiological basis of Asperger's syndrome is highlighted. Finally, we briefly touch upon the ‘Theory of Mind’ construct in autistic spectrum disorders. PMID:21407867

We study, computationally, the sedimentation of a sphere of higher mass in a steady, gravity-driven granular flow of otherwise identical spheres, on a rough inclined plane. Taking a hydrodynamic approach at the scale of the particle, we find the drag force to be given by a modified Stokes law and the buoyancy force by the Archimedes principle, with excluded volume effects taken into account. We also find significant differences between the hydrodynamic case and the granular case, which are highlighted.

Structural parallels between terrestrial microbialites and Martian sediments: are all cases of `Pareidolia'?

NASA Astrophysics Data System (ADS)

Rizzo, Vincenzo; Cantasano, Nicola

2017-10-01

The study analyses possible parallels of the microbialite-known structures with a set of similar settings selected by a systematic investigation from the wide record and data set of images shot by NASA rovers. Terrestrial cases involve structures both due to bio-mineralization processes and those induced by bacterial metabolism, that occur in a dimensional field longer than 0.1 mm, at micro, meso and macro scales. The study highlights occurrence on Martian sediments of widespread structures like microspherules, often organized into some higher-order settings. Such structures also occur on terrestrial stromatolites in a great variety of `Microscopic Induced Sedimentary Structures', such as voids, gas domes and layer deformations of microbial mats. We present a suite of analogies so compelling (i.e. different scales of morphological, structural and conceptual relevance), to make the case that similarities between Martian sediment structures and terrestrial microbialites are not all cases of `Pareidolia'.

Evaluating landfill aftercare strategies: A life cycle assessment approach.

PubMed

Turner, David A; Beaven, Richard P; Woodman, Nick D

2017-05-01

This study investigates the potential impacts caused by the loss of active environmental control measures during the aftercare period of landfill management. A combined mechanistic solute flow model and life cycle assessment (LCA) approach was used to evaluate the potential impacts of leachate emissions over a 10,000year time horizon. A continuum of control loss possibilities occurring at different times and for different durations were investigated for four different basic aftercare scenarios, including a typical aftercare scenario involving a low permeability cap and three accelerated aftercare scenarios involving higher initial infiltration rates. Assuming a 'best case' where control is never lost, the largest potential impacts resulted from the typical aftercare scenario. The maximum difference between potential impacts from the 'best case' and the 'worst case', where control fails at the earliest possible point and is never reinstated, was only a fourfold increase. This highlights potential deficiencies in standard life cycle impact assessment practice, which are discussed. Nevertheless, the results show how the influence of active control loss on the potential impacts of landfilling varies considerably depending on the aftercare strategy used and highlight the importance that leachate treatment efficiencies have upon impacts.

Championing telemedicine adoption and utilization in healthcare organizations in New Zealand.

PubMed

Al-Qirim, Nabeel

2007-01-01

This research explored the adoption and the utilisation of telemedicine (TM) in two healthcare organizations (HCOs) in New Zealand (NZ). The research utilised the technological innovation theories, as a guiding theoretical framework, to develop a set of potential determinants which could assist in understanding the adoption and the depth of the TM phenomenon in the two HCOs. Using case studies design, the findings across the two cases revealed that TM was adopted according to its cost-benefit analysis. Although this approach was found to be important in assessing the adoption of TM, not considering the importance of other factors, highlighted in this research, such as the compatibility and the trialability aspects of the TM technology had a detrimental impact on the success of TM in both cases. This research stressed the need for the tight coupling between the roles of both the administrative and the clinical managers in HCOs in order to champion TM adoption and diffusion and to overcome many of the barriers that could hinder telemedicine success in HCOs in NZ. The research points to other implications with respect to the literature and highlights further research in this important area.

Comparison of different interpolation operators including nonlinear subdivision schemes in the simulation of particle trajectories

Bensiali, Bouchra; Bodi, Kowsik; Ciraolo, Guido; Ghendrih, Philippe; Liandrat, Jacques

2013-03-01

In this work, we compare different interpolation operators in the context of particle tracking with an emphasis on situations involving velocity field with steep gradients. Since, in this case, most classical methods give rise to the Gibbs phenomenon (generation of oscillations near discontinuities), we present new methods for particle tracking based on subdivision schemes and especially on the Piecewise Parabolic Harmonic (PPH) scheme which has shown its advantage in image processing in presence of strong contrasts. First an analytic univariate case with a discontinuous velocity field is considered in order to highlight the effect of the Gibbs phenomenon on trajectory calculation. Theoretical results are provided. Then, we show, regardless of the interpolation method, the need to use a conservative approach when integrating a conservative problem with a velocity field deriving from a potential. Finally, the PPH scheme is applied in a more realistic case of a time-dependent potential encountered in the edge turbulence of magnetically confined plasmas, to compare the propagation of density structures (turbulence bursts) with the dynamics of test particles. This study highlights the difference between particle transport and density transport in turbulent fields.

Understanding the epidemiology of human H5N1 cases in Indonesia is important. The question of whether cases are clustered or not is unclear. An increase in clustered cases suggests greater transmissibility. In the present study, 107 confirmed and 302 suspected human H5N1 cases in Indonesia during 2005-2007 were analyzed for spatial and temporal distribution. Most confirmed cases (97.2%) occurred on two main islands (Java and Sumatera). There were no patterns of disease occurrence over time. There were also no correlations between occurrence patterns in humans and poultry. Statistical analysis showed confirmed cases were clustered within an area on Java island covered by 8 districts along the border of three neighboring provinces (Jakarta, West Java, and Banten). This study shows human H5N1 cases in Indonesia were clustered at two sites where there was a high rate of infection among poultry. These findings are important since they highlight areas of high risk for possible human H5N1 infection in Indonesia, thus, preventive measures may be taken.

Sodium fluoride PET (18F-NaF) has recently reemerged as a valuable method for detection of osseous metastasis, with recent work highlighting the potential of coadministered 18F-NaF and 18F-FDG PET/CT in a single combined imaging examination. We further examined the potential of such combined examinations by comparing dual tracer 18F-NaF18/F-FDG PET/CT with CT alone for detection of osseous metastasis. Seventy-five participants with biopsy-proven malignancy were consecutively enrolled from a single center and underwent combined 18F-NaF/18F-FDG PET/CT and diagnostic CT scans. PET/CT as well as CT only images were reviewed in blinded fashion and compared with the results of clinical, imaging, or histological follow-up as a truth standard. Sensitivity of the combined 18F-NaF/18F-FDG PET/CT was higher than that of CT alone (97.4% vs 66.7%). CT and 18F-NaF/18F-FDG PET/CT were concordant in 73% of studies. Of 20 discordant cases, 18F-NaF/18F-FDG PET/CT was correct in 19 (95%). Three cases were interpreted concordantly but incorrectly, and all 3 were false positives. A single case of osseous metastasis was detected by CT alone, but not by 18F-NaF/18F-FDG PET/CT. Combined 18F-NaF/18F-FDG PET/CT outperforms CT alone and is highly sensitive and specific for detection of osseous metastases. The concordantly interpreted false-positive cases demonstrate the difficulty of distinguishing degenerative from malignant disease, whereas the single case of metastasis seen on CT but not PET highlights the need for careful review of CT images in multimodality studies.

Patient-reported outcomes (PROs) are gaining recognition as key measures for improving the quality of patient care in clinical care settings. Three factors have made the implementation of PROs in clinical care more feasible: increased use of modern measurement methods in PRO design and validation, rapid progression of technology (eg, touchscreen tablets, Internet accessibility, and electronic health records), and greater demand for measurement and monitoring of PROs by regulators, payers, accreditors, and professional organizations. As electronic PRO collection and reporting capabilities have improved, the challenges of collecting PRO data have changed. To update information on PRO adoption considerations in clinical care, highlighting electronic and technical advances with respect to measure selection, clinical workflow, data infrastructure, and outcomes reporting. Five practical case studies across diverse health care settings and patient populations are used to explore how implementation barriers were addressed to promote the successful integration of PRO collection into the clinical workflow. The case studies address selecting and reporting of relevant content, workflow integration, previsit screening, effective evaluation, and electronic health record integration. These case studies exemplify elements of well-designed electronic systems, including response automation, tailoring of item selection and reporting algorithms, flexibility of collection location, and integration with patient health care data elements. They also highlight emerging logistical barriers in this area, such as the need for specialized technological and methodological expertise, and design limitations of current electronic data capture systems.

Chronic gastritis has a high incidence in adults, causing progressive destruction of glandular structures, favoring the development of gastric atrophy. The association of chronic gastritis with intestinal type metaplasia of gastric mucosa has a poor outcome as intestinal metaplasia is regarded as a precancerous lesion. Metaplasia is common in patients with Helicobacter pylori infection and also heavy smokers. The aim of our study was to evaluate the relationship between chronic gastritis and intestinal metaplasia. The study was conducted on a total of 1218 patients, aged between 5 and 90 years, who presented for dyspeptic disorders in the period 2007-2010 and were examined clinically and endoscopically. During the gastroscopic examination, fragments of gastric mucosa were collected for the histopathological study and for highlighting the H. pylori infection. For the histopathological study, the Hematoxylin-Eosin and PAS-Alcian Blue stains were performed, while for the immunohistochemical study the anti-TAG72 and anti-PCNA antibodies were used. A diagnosis of gastritis was established in 615 patients, representing approximately 50.5% of all cases. Most cases with gastritis were found in people of middle age. Gastritis was present in almost all age groups, from teenagers to the elders. Of the 615 cases of gastritis, urease test was positive in 353 patients, representing approximately 57.40% of all patients with gastritis. Histopathological examination identified the presence of intestinal metaplasia in 61.60% of patients with chronic gastritis, mostly complete metaplasia. PCNA immunohistochemistry revealed that cell proliferation processes are intensified in intestinal metaplasia. This study highlights the importance of chronic gastritis, intestinal metaplasia, and H. pylori infection in the etiopathogeny of gastric cancer.

In adopting a whole-of-society (WoS) approach that engages multiple stakeholders in public health policies across contexts, the authors propose that effective governance presents a challenge. The purpose of this paper is to highlight a case for how polycentric governance underlying the WoS approach is already functioning, while outlining an agenda to enable adaptive learning for improving such governance processes. Drawing upon a case study from Quebec, Canada, we employ empirically developed concepts from extensive, decades-long work of the 2009 Nobel laureate Elinor Ostrom in the governance of policy in nonhealth domains to analyze early efforts at polycentric governance in policies around overnutrition, highlighting interactions between international, domestic, state and nonstate actors and processes. Using information from primary and secondary sources, we analyze the emergence of the broader policy context of Quebec's public health system in the 20th century. We present a microsituational analysis of the WoS approach for Quebec's 21st century policies on healthy lifestyles, emphasizing the role of governance at the community level. We argue for rethinking prescriptive policy analysis of the 20th century, proposing an agenda for diagnostic policy analysis, which explicates the multiple sets of actors and interacting variables shaping polycentric governance for operationalizing the WoS approach to policymaking in specific contexts. © 2014 New York Academy of Sciences.

To characterize multiple evanescent white dot syndrome (MEWDS)-like lesions as diagnosed by clinical exam and fluorescein angiography (FA) to build an epidemiological profile of this disease and highlight the most common angiographical aspects. It is important to emphasize the existence of this syndrome and improve patients' information about the natural good course of this disease. A cross-sectional study including all FA performed from July 2006 to October 2012 (6,111 exams analyzed) in patients at our ophthalmic emergency department, with analysis of the different angiographic aspects of the MEWDS-diagnosed cases. Among the 6,111 angiographies analyzed, 15 MEWDS cases were detected; the patients ranged in age from 13 to 42 years old, and the male/female ratio was 60% to 40% (nine male and six female). The most common FA aspects included hyperfluorescent dots, dots and spots in the retinal mid-periphery, and foveal granularity in 46% of the cases. MEWDS has a good prognosis, with spontaneous involution, which makes it difficult to diagnose because of the delayed access to ophthalmological assistance, in special FA examination, which highlights the lesions. This study was possible due to the quick access facility at a private ophthalmic emergency department and examination by an experienced ophthalmologist, along with complementary diagnosis by FA and better perception of the patients, thus ensuring good prognosis.

Understanding Market Size and Reporting Gaps for Paediatric TB in Indonesia, Nigeria and Pakistan: Supporting Improved Treatment of Childhood TB in the Advent of New Medicines

PubMed Central

2015-01-01

Objective of the Study We sought to understand gaps in reporting childhood TB cases among public and private sector health facilities (dubbed “non-NTP” facilities) outside the network of national TB control programmes, and the resulting impact of under-reporting on estimates of paediatric disease burden and market demand for new medicines. Methodology Exploratory assessments were carried out in Indonesia, Nigeria and Pakistan, reaching a range of facility types in two selected areas of each country. Record reviews and interviews of healthcare providers were carried out to assess numbers of unreported paediatric TB cases, diagnostic pathways followed and treatment regimens prescribed. Main Findings A total of 985 unreported diagnosed paediatric TB cases were identified over a three month period in 2013 in Indonesia from 64 facilities, 463 in Pakistan from 35 facilities and 24 in Nigeria from 20 facilities. These represent an absolute additional annualised yield to 2013 notifications reported to WHO of 15% for Indonesia, 2% for Nigeria and 7% for Pakistan. Only 12% of all facilities provided age and sex-disaggregated data. Findings highlight the challenges of confirming childhood TB. Diagnosis patterns in Nigeria highlight a very low suspicion for childhood TB. Providers note the need for paediatric medicines aligned to WHO recommendations. Conclusion: How Market Data Can Support Better Public Health Interventions This study emphasises the impact of incomplete reporting on the estimation of disease burden and potential market size of paediatric TB medicines. Further studies on “hubs” (facilities treating large numbers of childhood TB cases) will improve our understanding of the epidemic, support introduction efforts for new treatments and better measure markets for new paediatric medicines.

2016-10-01

Critical digital ischemia is a rare, but serious complication of systemic sclerosis (SSc) and is not always due solely to the non-inflammatory angiopathy that characterizes the SSc disease process. Our objective was to illustrate the range of presentations and causes of critical digital ischemia in patients with SSc in order to highlight how optimal management is dependent upon establishing the correct diagnosis. Five cases exemplifying differential diagnoses were identified and their case notes reviewed in order to extract clinically relevant data and images. A review of the literature was performed in PubMed in English. Causes of critical digital ischemia included typical micro-angiopathic changes and proximal (large vessel) disease. One case highlighted the difficulty of ascertaining whether an inflammatory cause is also present in SSc/SLE overlap syndrome. Two cases demonstrated embolic causes (thromboembolism due to atrial fibrillation and septic emboli). Critical digital ischemia in patients with SSc requires thorough investigation in order to avoid missing additional potentially modifiable causes including large vessel disease, inflammation, embolism, infection, and paraneoplastic syndromes. A firm evidence base for current medical and surgical interventions is lacking, highlighting the need for further research into the optimum management of this rare, but painful, debilitating, and limb-threatening complication of SSc.

2014-03-01

Single-case research allows for an examination of behavior and can demonstrate the functional relation between intervention and outcome in pediatric psychology. This review highlights key assumptions, methodological and design considerations, and options for data analysis. Single-case methodology and guidelines are reviewed with an in-depth focus on visual and statistical analyses. Guidelines allow for the careful evaluation of design quality and visual analysis. A number of statistical techniques have been introduced to supplement visual analysis, but to date, there is no consensus on their recommended use in single-case research design. Single-case methodology is invaluable for advancing pediatric psychology science and practice, and guidelines have been introduced to enhance the consistency, validity, and reliability of these studies. Experts generally agree that visual inspection is the optimal method of analysis in single-case design; however, statistical approaches are becoming increasingly evaluated and used to augment data interpretation.

In the absence of any other conclusive forensic evidence, DNA profiling is the method of choice for body identification. This study focuses on the case of a carbonized corpse whose complete autosomal short tandem repeat (STR) profile could not lead to direct identification by the investigators. To assist in the progress of investigation, we endeavoured to determine the biogeographical origin and eye colour of the deceased individual. Along with Y chromosome and mitochondrial DNA analyses, we applied a next-generation sequencing (NGS) approach to the study of ancestry informative markers (AIMs) using the HID-Ion AmpliSeq™ Ancestry Panel launched by Thermo Fisher Scientific. This work gave us the opportunity to test this new technology in a real forensic case. Although this study highlights the benefits of such a combined approach, as it markedly improves the specificity of the biogeographical profile, it also underlines the need for the accurate characterization of a larger collection of reference populations and the necessity of caution in data interpretation.

Consumer attitudes and behaviours--key risk factors in an outbreak of Salmonella typhimurium phage type 12 infection sourced to chicken nuggets.

To identify the source and intervention methods for an outbreak of Salmonella Typhimurium phage type 12 in South Australia. Ten cases of S. Typhimurium phage type (PT) 12 infection were notified in South Australia in a four-week period from 7 May 1998. Nine cases and 27 controls were included in a case control study to test the hypothesis that illness was associated with the consumption of chicken nuggets. A significant association between illness and the consumption of one brand of chicken nuggets was determined, odds ratio undefined (95% CI undefined; p = undefined). Nine of nine cases and one of 27 controls reported eating these chicken nuggets. S. Typhimurium PT 12 was isolated from an opened sample of this particular brand of nuggets which had been retrieved from the home of one case. The implicated nuggets were essentially a raw product which had been 'flash fried' in contrast with other brands which were fully cooked. The investigation highlighted issues of inadequate labelling and consumer responses to labelling information which affect food safety. A media release to highlight to the consumer the need to cook frozen food properly and a voluntary recall of the 'flash fried' product was instigated as a result of these conclusions. Further action is needed to eliminate the potential hazard that consumers will perceive and handle 'flash fried' nuggets as if they are a cooked chicken product.

Proteinuria is common after renal transplantation and affects between 35%-45% of patients during the same year as their transplant. We report a case of dual pathology in the renal allograft as a cause of severe proteinuria. A 38-year-old male presented with end-stage renal disease. He underwent live related renal allograft transplant. His immediate post-transplant period was unremarkable. He developed rise in serum creatinine (2.1 mg/dl) 6 months after transplant and was biopsied. He was diagnosed as a case of acute cellular rejection type Ib with suspicion for antibody mediated rejection. He was treated with methylprednisolone to which he showed a good response with return of serum creatinine to 1.6 mg/dl. Subsequently, he developed a nephrotic range proteinuria 6 months after this episode of rejection. Repeat biopsy was performed. He was diagnosed as a case of immune complex mediated glomerulonephritis (GN) (morphologically consistent with pattern of membranoproliferative glomerulonephritis) with chronic humoral rejection in the form of transplant glomerulopathy (TG). IHC for C4d and immunofluorescence studies were instrumental making the diagnosis. He was treated with steroids and rituximab to which he showed a good response with remission of proteinuria. This case highlights the importance of picking up dual pathology in an allograft biopsy to ensure appropriate therapy. The role of C4d and its correct interpretation is further highlighted, especially with regard to pattern (granular versus linear) and location (glomerular capillaries versus peritubular capillaries).

Highlights: • Waste management opportunities in small and medium companies were highlighted. • Pilot scale program for windrow co-composting of natural casings was investigated. • Compost preparation, characterization and application phases were discussed. • Natural casings co-composting has proved more viable and cost effective solution. - Abstract: After studying the waste management opportunities in small and medium companies of natural casings, composting has proved more viable and cost effective solution for the valorization of these types of waste, but its feasibility depends on the final product value. This paper investigated a pilot scale program for the windrow co-composting of naturalmore » casings waste with sheep manure and dead leaves incorporation. Processing, characterization and application of the final compost were described and the final compost was analyzed for pathogens, metals, nutrients, maturity, and agronomic parameters. The results showed that all test result levels were below the limits specified in the EPA regulations published in Title 40, Section 503, of the Code of Federal Regulations (40 CFR 503). Moreover, the agronomic value tests which include nutrients, organic matter, pH, electrical conductivity, etc. showed that the compost had high organic-matter content and low salt content, all of which indicate good compost characteristics. The ratio of nitrogen (N), phosphorus (P), and potassium (K), or NPK ratio, was measured at 1.6–0.9–0.7. Reported units are consistent with those found on fertilizer formulations.« less

MELAS (mitochondrial cytopathy, encephalomyopathy, lactic acidosis and stroke-like episodes) is a syndrome in which signs and symptoms of gastrointestinal disease are uncommon if not rare. We describe the case of a young woman who presented as an acute surgical emergency, diagnosed as toxic megacolon necessitating an emergency total colectomy. MELAS syndrome was suspected postoperatively owing to persistent lactic acidosis and neurological symptoms. The diagnosis was later confirmed with histological and genetic studies. This case highlights the difficulties in diagnosing MELAS because of its unpredictable presentation and clinical course. We therefore recommend a high index of suspicion in cases of an acute surgical abdomen with additional neurological features or raised lactate. PMID:24417855

Routine clinical and pathological evaluations to determine the relationship between different lesions are often not completely conclusive. Interestingly, detailed genetic analysis of tumor samples may provide important additional information and identify second primary lung cancers. In the present study, we report cases of two synchronous lung adenocarcinomas composed of two distinct pathological subtypes with different EGFR gene mutations: a homozygous deletion in exon 19 of the papillary adenocarcinoma subtype and a point mutation of L858R in exon 21 of the tubular adenocarcinoma. The present report highlights the clinical importance of molecular cancer biomarkers to guide management decisions in cases involving multiple lung tumors. PMID:29090842

Nanomaterial Case Study: Nanoscale Silver in Disinfectant ...

EPA Pesticide Factsheets

EPA announced the release of the final report, Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray. This report represents a case study of engineered nanoscale silver (nano-Ag), focusing on the specific example of nano-Ag as possibly used in disinfectant sprays. This case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. The document does not draw conclusions about potential risks. Instead, it is intended to be used as part of a process to identify what is known and unknown about nano-Ag in a selected application. In turn, the external review draft of the document provided a starting point to identify and prioritize possible research directions to support future assessments of nanomaterials. The information presented in the case study and the questions raised in this document are a foundation for a process to determine priorities among various research topics and directions. After that process has been completed, a final chapter will be added to this document to summarize highlights from preceding chapters and the major research issues that have emerged.

Feeding raw meat-based diets (RMBD) to companion animals raises public health concerns for both animals and humans. While considerable attention has been paid to bacterial contamination of commercial pet food, few literature studies have investigated foodborne disease in companion animals. Salmonellosis is reported to be infrequent in cats but no known data or studies estimating feline salmonellosis are available or large-scale epidemiological studies assessing Salmonella risk factors. Two highly suspected cases of salmonellosis in two cats fed with a commercial frozen poultry RMBD are presented, for the first time from the same household. The clinical presentation, diagnostics, treatment and follow-up are reported and the zoonotic implications are discussed. This case highlights the health risks posed to both animals and owners by feeding RMBD to pets, and suggests that these risks should be considered by veterinary practitioners.

This article aims to provide a review of music sponsorship to market cigarettes in sub-Saharan Africa. Using analysis of previously secret corporate documents from British American Tobacco (BAT) and focusing on two separate case studies of sponsorship in Africa, Nigeria and South Africa, the paper illustrates how tobacco companies have sought to undermine health legislation from 1990 to 2001. Both case studies suggest that music is an important marketing tool in Africa because it can effectively target young consumers; has a universal appeal; transcends barriers to communication imposed by limited literacy and language barriers; has a long-term appeal and can be successful in undermining tobacco control measures. The case studies highlight the limitations of national regulatory efforts and reinforce the significance of the implementation of the WHO’s Framework Convention on Tobacco Control in Africa, a critical region for the convention’s success.

Communicating with scientific graphics: A descriptive inquiry into non-ideal normativity.

2017-06-01

Scientists' graphical practices have recently become a target of inquiry in the philosophy of science, and in the cognitive sciences. Here I supplement our understanding of graphical practices via a case study of how researchers crafted the graphics for scientific publication in the field of circadian biology. The case highlights social aspects of graphical production which have gone understudied - especially concerning the negotiation of publication. I argue that it also supports a challenge to the claim that empirically-informed "cognitive design principles" offer an apt understanding of the norms of success which govern good scientific graphic design to communicate data and hypotheses to other experts. In this respect, the case-study also illustrates how "descriptive" studies of scientific practice can connect with normative issues in philosophy of science, thereby addressing a central concern in recent discussions of practice-oriented philosophy of science.

Bringing 'Light, Life and Happiness': British American Tobacco and musicsponsorship in sub-Saharan Africa.

PubMed

Patel, Preeti; Okechukwu, Cassandra A; Collin, Jeff; Hughes, Belinda

This article aims to provide a review of music sponsorship to market cigarettes in sub-Saharan Africa. Using analysis of previously secret corporate documents from British American Tobacco (BAT) and focusing on two separate case studies of sponsorship in Africa, Nigeria and South Africa, the paper illustrates how tobacco companies have sought to undermine health legislation from 1990 to 2001. Both case studies suggest that music is an important marketing tool in Africa because it can effectively target young consumers; has a universal appeal; transcends barriers to communication imposed by limited literacy and language barriers; has a long-term appeal and can be successful in undermining tobacco control measures. The case studies highlight the limitations of national regulatory efforts and reinforce the significance of the implementation of the WHO's Framework Convention on Tobacco Control in Africa, a critical region for the convention's success.

Governance: Blending Bureaucratic Rules with Day to Day Operational Realities Comment on "Governance, Government, and the Search for New Provider Models".

Richard Saltman and Antonio Duran take up the challenging issue of governance in their article "Governance, Government and the Search for New Provider Models," and use two case studies of health policy changes in Sweden and Spain to shed light on the subject. In this commentary, I seek to link their conceptualization of governance, especially its interrelated roles at the macro, meso, and micro levels of health systems, with the case studies on which they report. While the case studies focus on the shifts in governance between the macro and meso levels and their impacts on achievement of desired policy outcomes, they also highlight the need to better integrate the dynamics of day to day operations within micro organizations into the overall governance picture. © 2016 by Kerman University of Medical Sciences.

  The purpose of the present study was to evaluate the correlation between clinical and histopathological diagnoses of periapical inflammatory lesions, focusing mainly on cystic conditions.   Files dating from 1998 to 2006 at the Oral Pathology Laboratory, School of Dentistry, Alfenas Federal University, Brazil, were reviewed to identify cases with histopathological diagnoses of periapical inflammatory lesions. A total of 1788 files were analyzed, and 255 cases were identified with clinical diagnoses of periapical inflammatory lesions.   The most prevalent clinical diagnosis was apical periodontal cyst (59%), followed by periapical granuloma (20%), and dentoalveolar abscess (2%). After histopathological analysis, 53% of the cases represented apical periodontal cyst, 42% periapical granuloma, and 5% dentoalveolar abscess.   The outcomes of the present study show a high prevalence of periapical cysts among periapical inflammatory lesions. Moreover, this study highlights the importance of histopathological evaluation for the correct diagnosis of periapical inflammatory lesions. © 2011 Blackwell Publishing Asia Pty Ltd.

Faces of integration

PubMed Central

Williams, Paul; Sullivan, Helen

2009-01-01

Theme Two central themes permeate this paper—the interplay between structure and agency in integration processes and the extent to which this is mediated through sensemaking by individual actors. Case study The empirical base for the paper is provided by case study research from Wales which draws on examples of different types of integration in health and social care. The individual case studies highlight different interpretations of integration set against a background of the resources involved, processes employed and outcomes achieved. Discussion A wide ranging discussion exposes the complex interplay and dynamics between structural factors and the manner in which they enable or constrain integration, and individual actors realising their potential agency through leadership, professionalism and boundary spanning to influence outcomes. The importance of structure and agency complementing each other to determine effective integration is emphasised, together with the scope that is available for interpretation and meaning by individual actors within the contested discourse of integration.

The case studies presented here illustrate the poignant reality of life for mothers and children in rural India. We highlight the challenges of achieving millennium development goals (MDGs) 4 and 5, by exploring the reasons behind maternal and childhood mortality using the three-delays model as a framework. Gender disparities, lack of empowerment of women, poor understanding of life-threatening illness, the inability to know when and where to seek help, security issues, deficiencies in understanding cultural perceptions, poorly equipped health facilities and a lack of skilled personnel are all highlighted. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

Chikungunya virus (CHIKV) appeared for the first time in the Western Hemisphere--the French West Indies--in December of 2013. From there, the virus has spread to other Caribbean islands. Following the diagnosis of first autochthonous CHIKV cases in the Caribbean island of Saint Martin, a large outbreak is ongoing in the Americas. As of September 12, 2014, a total of 706,093 suspected and 9803 confirmed CHIKV cases have been reported in the Americas. This case study highlights the possibility of false-negative immunochromatographic CHIKV immunoglobulin M (IgM) tests and the need of confirmatory tests for suspected cases. Moreover, a greater spread of virus together with the presence of a mosquito vector (Aedes albopictus) enhances the risk of autochthonous transmission in Europe.

Alternative approaches to analytical designs in occupational injury epidemiology.

Mittleman, M A; Maldonado, G; Gerberich, S G; Smith, G S; Sorock, G S

1997-08-01

In this paper, we discuss the theoretical framework upon which observational studies of occupational injuries are based. Following a general description of how causal effects are estimated, the challenges faced by researchers working in this area are outlined, with an emphasis on case-control studies. These challenges include defining the at-risk period for workers whose tasks change over time and whose hazard period may be very brief, evaluating the underreporting of both exposures and injuries, and considering the effects of multiple injuries per individual on study design and data analysis. We review both the theoretical and practical considerations in the design and conduct of traditional case-control studies, based on the collection of individual level data, as well as other approaches, such as using information culled from administrative and descriptive databases, and case-control studies in which the plant or work site is the unit of analysis. The case-crossover design is also reviewed and its utility for reducing confounding due to differences between individuals by self-matching is highlighted. While this design has not yet been applied to the work setting, its potential for increasing our understanding of the causes of acute-onset occupational injuries seems promising. Finally, a variety of hybrid designs are discussed, including combinations of case-control, case-crossover, and cohort designs.

Beyond Compliance Checking: A Situated Approach to Visual Research Ethics.

PubMed

Lenette, Caroline; Botfield, Jessica R; Boydell, Katherine; Haire, Bridget; Newman, Christy E; Zwi, Anthony B

2018-03-19

Visual research methods like photography and digital storytelling are increasingly used in health and social sciences research as participatory approaches that benefit participants, researchers, and audiences. Visual methods involve a number of additional ethical considerations such as using identifiable content and ownership of creative outputs. As such, ethics committees should use different assessment frameworks to consider research protocols with visual methods. Here, we outline the limitations of ethics committees in assessing projects with a visual focus and highlight the sparse knowledge on how researchers respond when they encounter ethical challenges in the practice of visual research. We propose a situated approach in relation to visual methodologies that encompasses a negotiated, flexible approach, given that ethical issues usually emerge in relation to the specific contexts of individual research projects. Drawing on available literature and two case studies, we identify and reflect on nuanced ethical implications in visual research, like tensions between aesthetics and research validity. The case studies highlight strategies developed in-situ to address the challenges two researchers encountered when using visual research methods, illustrating that some practice implications are not necessarily addressed using established ethical clearance procedures. A situated approach can ensure that visual research remains ethical, engaging, and rigorous.

Teleoperated medical robotic systems allow procedures such as surgeries, treatments, and diagnoses to be conducted across short or long distances while utilizing wired and/or wireless communication networks. This study presents a systematic review of the relevant literature between the years 2004 and 2015, focusing on medical teleoperated robotic systems which have witnessed tremendous growth over the examined period. A thorough insight of telerobotics systems discussing design concepts, enabling technologies (namely robotic manipulation, telecommunications, and vision systems), and potential applications in clinical practice is provided, while existing limitations and future trends are also highlighted. A representative paradigm of the short-distance case is the da Vinci Surgical System which is described in order to highlight relevant issues. The long-distance telerobotics concept is exemplified through a case study on diagnostic ultrasound scanning. Moreover, the present review provides a classification into short- and long-distance telerobotic systems, depending on the distance from which they are operated. Telerobotic systems are further categorized with respect to their application field. For the reviewed systems are also examined their engineering characteristics and the employed robotics technology. The current status of the field, its significance, the potential, as well as the challenges that lie ahead are thoroughly discussed.

The delivery of a macrosomic infant is a relatively common situation. It can put mother and fetus at high risk. The main maternal complications are the increase in cesarean rates, postpartum hemorrhage and cervicovaginal traumatic lacerations. The main fetal complication is shoulder dystocia increasing the risk of brachial plexus. The objective was to identify risk factors and maternal-fetal complications associated with fetal macrosomia. Comparative retrospective study conducted at Kairouan University Hospital maternity unit in 2010. We compared a group of 820 cases of macrosomic infants to a control group of 800 cases of infants born in the same period of time. During the study period we collected clinical data of 820 macrosomic cases on a total of 7.495 deliveries, corresponding to a total incidence of 10.94%. Several factors predisposing to fetal macrosomia were highlighted: Maternal age> 35 years was present in 28.5% of cases; Maternal obesity was found in 45% of cases; A personal history of macrosomia was noted in 28,8% of cases; Prolonged pregnancies > 41 weeks of amenorrhoea was noted in 35.6% of cases; Multiparity was found in 47% of cases. Maternal complications were essentially postpartum hemorrhage: 71 cases and genital traumas: 24 cases. Perinatal complications were dominated by shoulder dystocia: 27 cases (3.3%). Traumatic postpartum complications were found in 11.6%.

The United Arab Emirates is a rapidly developing country with recent expansion in construction and manufacturing. To investigate the occurrence and outcomes following occupational traumatic brain injury (TBI) requiring hospital admission. Records for all TBI cases admitted to an Abu Dhabi hospital between 2005 and 2009 were reviewed. Data on mechanisms of occupational injuries, Glasgow Coma Scale (GCS) on admission and Glasgow Outcome Scale (GOS) on follow-up, were analysed. Of 581 TBI cases reviewed, 56 (10%) cases were reported as occupational by either the patient or the informant accompanying the patient. All cases were male migrants, and 63% were aged 25-44. Falls accounted for 63% of cases, falling objects 34% and motor vehicle collisions 4%. Median GCS score was 13 for all cases. Median hospital stay was 7.5 days. Intensive care unit admission data were available in 47 cases, of which 34% (16) were admitted with a median stay of 5 days. GOS data were available in 95% (53) of cases, with good recovery in 81% cases, moderate-to-severe disability in 11% of cases and death in 8% (4) cases. Occupational TBI requiring hospitalization is most frequently due to falls and falling objects, with potentially grave consequences. This study further highlights the urgent need to implement preventative measures to improve construction worker safety.

Previous research highlights barriers to clinical psychologists conducting research, but has rarely examined U.K. clinical psychologists. The study investigated U.K. clinical psychologists' self-reported research output and tested part of a theoretical model of factors influencing their intention to conduct research. Questionnaires were mailed to 1,300 U.K. clinical psychologists. Three hundred and seventy-four questionnaires were returned (29% response-rate). This study replicated in a U.K. sample the finding that the modal number of publications was zero, highlighted in a number of U.K. and U.S. studies. Research intention was bimodally distributed, and logistic regression classified 78% of cases successfully. Outcome expectations, perceived behavioral control and normative beliefs mediated between research training environment and intention. Further research should explore how research is negotiated in clinical roles, and this issue should be incorporated into prequalification training. © 2012 Wiley Periodicals, Inc.

POLIPHON (POlarization-LIdar PHOtometer Networking) retrieval consists in the vertical separation of two/three particle components in aerosol mixtures, highlighting their relative contributions in terms of the optical properties and mass concentrations. This method is based on the specific particle linear depolarization ratio given for different types of aerosols, and is applied to the new polarized Micro-Pulse Lidar (P-MPL). Case studies of specific climate-relevant aerosols (dust particles, fire smoke, and pollen aerosols, including a clean case as reference) observed over Barcelona (Spain) are presented in order to evaluate firstly the potential of P-MPLs measurements in combination with POLIPHON for retrieving the vertical separation of those particle components forming aerosol mixtures and their properties.

This case report highlights an unusual osseous spinal presentation of a well described disease, hydatidosis. A 59-year-old woman presented with increasing back pain and bilateral radiculopathy. Examination disclosed symptoms of spinal stenosis and urinary incontinence. Radiographs showed an expansive lytic lesion affecting the pelvic bones with destruction of the bone cortex. Laboratory analyses were performed and the patient underwent CT and MRI studies. Serology for Echinococcus was positive. When assessing sciatica, low back pain or lower limb weakness the pelvic cavity should be examined for hidden disease that might explain the neurological symptoms. Hydatid disease of bone should be considered in the differential diagnosis of any bone mass discovered in the human body. Diagnosis was delayed in this case because the pelvic cavity was not studied when radiculopathy symptoms started and there was no coexisting visceral involvement.

Both genetic and non-genetic environmental factors are involved in the etiology of neural tube defects (NTD) which affect 0.5-2/1000 pregnancies worldwide. This study aimed to explore the risk factors for the development of NTD in Saudi population, and highlight identifiable and preventable causes. Similar studies are scarce in similar populations ofthe Arabian Peninsula and North Africa. This is an unmatched concurrent case-control study including NTD cases born at King Khalid University Hospital, Riyadh during a 4-year period (2002-2006). The case-control study included 25 cases and 125 controls (case: control ratio of 1:5). Years of formal education, employment, household environment (including availability of air conditioning) and rate of parental consanguinity did not differ between mothers of cases and controls. Significantly higher proportion of mothers of cases had history of stillbirth compared to control mothers (16% vs 4.1%, P=0.02). Also family history of hydrocephalus and congenital anomalies were more prevalent in cases than controls (P values=0.0000 and 0.003, respectively). There was significant protective effect of periconceptional folic acid consumption both prior to conception (OR 0.02, 95% CI 0.00-0.07) and during the first 6 weeks of conception (OR 0.13, 95% CI 0.04-0.39). Further research, including a larger cohort, is required to enable ascertainment of gene-nutrient and gene environment interactions associated with NTD in Saudi Arabia.

Technologic advances in health care have often outpaced our ability to integrate the technology efficiently, establish best practices for its use, and develop policies to regulate and evaluate its effectiveness. However, these may be insufficient reasons to put the brakes on innovation-particularly those "disruptive innovations" that challenge the status quo and have the potential to produce better outcomes in a number of important areas. This article discusses the concept of disruptive innovation and highlights data supporting its necessity within health care in general and nursing in particular. Focusing on telehealth as a case study in disruptive innovation, the author provides examples of its application and reviews literature that examines its effectiveness in both nursing practice and education.

Orrell, Alice C.; Homer, Juliet S.; Bender, Sadie R.

This document presents a case study of energy policies in Texas related to power system transformation, renewable energy and distributed energy resources (DERs). Texas has experienced a dramatic increase in installed wind capacity, from 116 MW in 2000 to over 15,000 MW in 2015. This achievement was enabled by the designation of Competitive Renewable Energy Zones (CREZs) and new transmission lines that transmit wind to load centers. This report highlights nascent efforts to include DERs in the ERCOT market. As costs decline and adoption rates increase, ERCOT expects distributed generation to have an increasing effect on grid operations, while bringingmore » potentially valuable new resources to the wholesale markets.« less

There is no adequate profile of domestic violence in Pakistan although this issue is frequently highlighted by the media. This case study used qualitative and quantitative methods to explore the nature and forms of domestic violence, circumstances, impact and coping mechanisms amongst selected women victims in Karachi. Violence was a continuum: all the women reported verbal abuse, often escalating into physical, emotional, sexual and economic abuse. The husband was the most common perpetrator. Women suffered in silence due to sociocultural norms, misinterpretation of religious beliefs, subordinate status, economic dependence and lack of legal redress. Besides short-term local measures, public policy informed by correct interpretation of religion can bring about a change in prevailing societal norms.

To gain an in-depth understanding of the decision-making processes involved in the discharge of older people admitted to hospital from home and discharged to a care home, as described in the case records. The decision for an older person to move into a care home is significant and life-changing. The discharge planning literature for older people highlights the integral role of nurses in supporting and facilitating effective discharge. However, little research has been undertaken to explore the experiences of those discharged from hospital to a care home or the processes involved in decision-making. A purposive sample of 10 cases was selected from a cohort of 100 individuals admitted to hospital from home and discharged to a care home. Cases were selected to highlight important personal, relational and structural factors thought to affect the decision-making process. Narrative case studies were created and were thematically analysed to explore the perspectives of each stakeholder group and the conceptualisations of risk which influenced decision-making. Care home discharge decision-making is a complex process involving stakeholders with a range of expertise, experience and perspectives. Decisions take time and considerable involvement of families and the multidisciplinary team. There were significant deficits in documentation which limit the understanding of the process and the patient's voice is often absent from case records. The experiences of older people, families and multidisciplinary team members making care home decisions in the hospital setting require further exploration to identify and define best practice. Nurses have a critical role in the involvement of older people making discharge decisions in hospital, improved documentation of the patient's voice is essential. Health and social care systems must allow older people time to make significant decisions about their living arrangements, adapting to changing medical and social needs. © 2018 John Wiley & Sons Ltd.

The Prototheca species is achlorophyllic algae and rarely causes human infection. Human protothecosis presents clinically as a cutaneous infection, olecranon bursitis, and disseminated systemic disease. We report a case of human cutaneous protothecosis involving the left wrist. A 68-year-old man presented with an ill-defined erythematous lesion with crust at the dorsal aspect of his left wrist. A punch biopsy was performed to reveal the histologic features of granulomatous inflammation with necrosis at the upper dermis, containing Prototheca organisms, of which, the characteristic features were highlighted by special staining. Through a molecular study, the Prototheca zopfii species was identified.

Angiolymphoid hyperplasia with eosinophilia is a rare and benign vascular tumor whose etiology remains uncertain. It clinically presents itself by angiomatous papules or nodules located on the head and neck. Many controversies in the literature are found in relation to angiolymphoid hyperplasia with eosinophilia and Kimura's disease - its main differential diagnosis - due to their clinical and histopathological similarities. However, currently, most studies agree that they are distinct diseases. The present case illustrates a characteristic description of angiolymphoid hyperplasia with eosinophilia and also highlights the main differences with Kimura's disease. PMID:29186256

Hymenoptera stings lead to a myriad of neurologic manifestations by the mechanism of immediate or delayed hypersensitivity reactions. The more common form of polyneuropathy associated with these stings is the acute inflammatory demyelinating type. We describe a 6-year-old girl, who developed progressive, symmetrical, ascending weakness within 3 days after a bee sting. Serial nerve conduction studies confirmed acute, motor-predominant axonal polyneuropathy. Use of intravenous immunoglobulin induced halt of progression, prompt stabilization and a gradual recovery. This case highlights that even a single honey-bee sting can result in acute-onset axonal variety of polyneuropathy in children.

Various diagnostic characteristics associated with neurocysticercosis have been well studied; however, their potential to be implicated in other differential diagnoses has not been well demonstrated. We report the case of a 55-year-old Hispanic man who underwent a Chiari decompression surgery, which was complicated with hydrocephalus. Despite a ventriculoperitoneal shunt placement, he continued to have headaches and was soon found to have several skull base subarachnoid lesions, which were later diagnosed as the sequelae of an active neurocysticercosis infection.

Few studies have been conducted to investigate drug effects on spontaneous abortion risk. The objective of the present study was to evaluate the potential association between first trimester drug exposure and spontaneous abortion occurrence. The authors performed a nested case-control study using data from TERAPPEL, a French medical database. Cases were the women who had a spontaneous abortion (before the 22nd week of amenorrhea) and controls were women who gave birth to a child. Analyzed variables were: maternal age, obstetric history, tobacco, and alcohol and drug consumption during the first trimester of pregnancy. For comparison of drug exposures between cases and controls, the authors calculated odds ratios (ORs) by means of multivariate logistic regressions adjusted on age and on other drug exposures. The study included 838 cases and 4,508 controls that were identified in the database. In adjusted analyses, cases were more exposed than controls to "non-selective monoamine reuptake inhibitors" [OR=2.2 (CI 95% 1.5-3.3)], "antiprotozoals" [OR = 1.6 (CI 95% 1.1 - 2.5)] and "centrally acting antiobesity products" [OR = 3.4 (CI 95% 1.9 - 6.2)]. Conversely, controls were more exposed than cases to H1 antihistamines [OR = 0.6 (CI 95% 0.4 - 0.9)]. This exploratory study highlights some potential associations between first trimester drug exposure and risk of spontaneous abortion. Further studies have to be carried out to investigate these findings.

To illustrate an approach to data analysis in qualitative case study methodology. There is often little detail in case study research about how data were analysed. However, it is important that comprehensive analysis procedures are used because there are often large sets of data from multiple sources of evidence. Furthermore, the ability to describe in detail how the analysis was conducted ensures rigour in reporting qualitative research. The research example used is a multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Data analysis was conducted using a framework guided by the four stages of analysis outlined by Morse ( 1994 ): comprehending, synthesising, theorising and recontextualising. The specific strategies for analysis in these stages centred on the work of Miles and Huberman ( 1994 ), which has been successfully used in case study research. The data were managed using NVivo software. Literature examining qualitative data analysis was reviewed and strategies illustrated by the case study example provided. Discussion Each stage of the analysis framework is described with illustration from the research example for the purpose of highlighting the benefits of a systematic approach to handling large data sets from multiple sources. By providing an example of how each stage of the analysis was conducted, it is hoped that researchers will be able to consider the benefits of such an approach to their own case study analysis. This paper illustrates specific strategies that can be employed when conducting data analysis in case study research and other qualitative research designs.

INTRODUCTION: Tuberculosis (TB) in the developing countries presents with both pulmonary and extrapulmonary manifestations. Breast TB, however, remains a rare presentation. Its importance lies in the fact that it may mimic malignancy or present as inflammatory lump/abscess. AIMS AND OBJECTIVE: The aim of the present study is to highlight the importance of breast TB and its diagnostic challenges. MATERIALS AND METHODS: It was a retrospective study conducted at a tertiary care hospital, over 2 years between 2013 and 2015 during which eight cases of breast lesions were diagnosed as of tubercular origin. RESULTS: Granulomas were seen in five cases while three cases revealed only few epithelioid cells, and necrosis was seen in all cases on fine-needle aspiration cytology. Histopathological evaluation was available in six out of the eight cases, while acid–fast bacilli were positive in three cases, the characteristic granulomas were seen in all the six cases evaluated. CONCLUSION: Significance of TB breast lies in the fact that it may masquerade as breast malignancy or pyogenic abscess. India is a developing country where TB is endemic, a high index of suspicion should be expressed in evaluating breast masses, and TB should be considered in the differential diagnosis. PMID:29692584

Fisheries industry in India is an unorganized sector of occupation where considerable proportion of workers is female. However, the prevalent gender inequality in terms of task allocation, wages, and other welfare facilities makes the men as dominant workforce. Furthermore, there are occasions when incidents of workplace violence take place. The present study was conducted to find the prevalence of workplace violence at worksite and study gender bias in such events. In a cross-sectional study 171 fishermen and fisherwomen were interviewed to collect information about workplace violence. The overall prevalence of workplace violence reported was 14.6%. This included 2 (8%) cases of physical assault, 1 (4%) case of sexual harassment of fisherwoman by her colleague and 22 (88%) cases of verbal abuse. A significant (p=0.002) association was found between gender and verbal abuse at the workplace. In conclusion, this study highlighted the occurrence of workplace violence among fishery workers in India. There was a gender bias towards females that can be attributed to male dominance in this occupation.
