Access to primary health care services for Indigenous peoples: A framework synthesis.
Davy, Carol; Harfield, Stephen; McArthur, Alexa; Munn, Zachary; Brown, Alex
2016-09-30
Indigenous peoples often find it difficult to access appropriate mainstream primary health care services. Securing access to primary health care services requires more than just services that are situated within easy reach. Ensuring the accessibility of health care for Indigenous peoples who are often faced with a vast array of additional barriers including experiences of discrimination and racism, can be complex. This framework synthesis aimed to identify issues that hindered Indigenous peoples from accessing primary health care and then explore how, if at all, these were addressed by Indigenous health care services. To be included in this framework synthesis papers must have presented findings focused on access to (factors relating to Indigenous peoples, their families and their communities) or accessibility of Indigenous primary health care services. Findings were imported into NVivo and a framework analysis undertaken whereby findings were coded to and then thematically analysed using Levesque and colleague's accessibility framework. Issues relating to the cultural and social determinants of health such as unemployment and low levels of education influenced whether Indigenous patients, their families and communities were able to access health care. Indigenous health care services addressed these issues in a number of ways including the provision of transport to and from appointments, a reduction in health care costs for people on low incomes and close consultation with, if not the direct involvement of, community members in identifying and then addressing health care needs. Indigenous health care services appear to be best placed to overcome both the social and cultural determinants of health which hamper Indigenous peoples from accessing health care. Findings of this synthesis also suggest that Levesque and colleague's accessibility framework should be broadened to include factors related to the health care system such as funding.

Background Routinely conducting case finding (also commonly referred to as screening) in patients with chronic illness for depression in primary care appears to have little impact. We explored the views and experiences of primary care nurses, doctors and managers to understand how the implementation of case finding/screening might impact on its effectiveness. Methods Two complementary qualitative focus group studies of primary care professionals including nurses, doctors and managers, in five primary care practices and five Community Health Partnerships, were conducted in Scotland. Results We identified several features of the way case finding/screening was implemented that may lead to systematic under-detection of depression. These included obstacles to incorporating case finding/screening into a clinical review consultation; a perception of replacing individualised care with mechanistic assessment, and a disconnection for nurses between management of physical and mental health. Far from being a standardised process that encouraged detection of depression, participants described case finding/screening as being conducted in a way which biased it towards negative responses, and for nurses, it was an uncomfortable task for which they lacked the necessary skills to provide immediate support to patients at the time of diagnosis. Conclusion The introduction of case finding/screening for depression into routine chronic illness management is not straightforward. Routinized case finding/screening for depression can be implemented in ways that may be counterproductive to engagement (particularly by nurses), with the mental health needs of patients living with long term conditions. If case finding/screening or engagement with mental health problems is to be promoted, primary care nurses require more training to increase their confidence in raising and dealing with mental health issues and GPs and nurses need to work collectively to develop the relational work required to promote cognitive participation in case finding/screening.

This paper focuses mainly on explanations and lessons from a research-based programme for identifying undiagnosed type 2 diabetes and high risk. In addition to outlining key quantitative findings, we specifically aim to explore reasons for low uptake from the perspective of primary care staff involved. The MY-WAIST study was conducted in UK primary care and included the use of oral glucose tolerance tests (OGTTs) and waist measurement. Qualitative data from interviews with healthcare providers and records of meetings were analysed thematically. The key quantitative finding was low uptake of the assessments offered (8.6% overall, 2.6% in inner-city locations with high South Asian residency). In addition to confirming patient-reported barriers including those associated with OGTTs, qualitative findings highlighted a number of primary care provider barriers, including limited staff capacity. Interviewees suggested that those who attended were typically the 'worried well' rather than those from hard-to-reach groups. Implications discussed include the impact of low uptake on the usefulness of the quantitative data obtained, and lessons relevant to research design. Relevance to current guidance regarding early identification strategies is discussed and the importance of addressing the needs of less accessible groups is highlighted.

Primary central nervous system (CNS) lymphomas are uncommon and their management differs significantly from that of other malignant tumors involving the CNS. This article explains how the imaging findings often suggest the diagnosis early. The typical findings in immunocompetent patients consist of a supratentorial intraaxial mass that enhances homogeneously. Other findings to evaluate include multifocality and incomplete ring enhancement. The differential diagnosis of primary CNS lymphomas should consider mainly other malignant tumors of the CNS such as glioblastomas or metastases. Primary CNS lymphomas tend to have less edema and less mass effect; they also tend to spare the adjacent cortex. Necrosis, hemorrhage, and calcification are uncommon in primary CNS lymphomas. Although the findings in morphologic sequences are characteristic, they are not completely specific and atypical types are sometimes encountered. Advanced imaging techniques such as diffusion or especially perfusion provide qualitative and quantitative data that play an important role in differentiating primary CNS lymphomas from other brain tumors.

Family physicians' perspectives on interprofessional teamwork: Findings from a qualitative study.
Szafran, Olga; Torti, Jacqueline M I; Kennett, Sandra L; Bell, Neil R
2018-03-01
The aim of this study was to describe family physicians' perspectives of their role in the primary care team and factors that facilitate and hinder teamwork. A qualitative study was conducted employing individual interviews with 19 academic/community-based family physicians who were part of interprofessional primary care teams in Edmonton, Alberta, Canada. Professional responsibilities and roles of physicians within the team and the facilitators and barriers to teamwork were investigated. Interviews were audiotaped, transcribed and analysed for emerging themes. The study findings revealed that family physicians consistently perceived themselves as having the leadership role on in the primary care team. Facilitators of teamwork included: communication; trust and respect; defined roles/responsibilities of team members; co-location; task shifting to other health professionals; and appropriate payment mechanisms. Barriers to teamwork included: undefined roles/responsibilities; lack of space; frequent staff turnover; network boundaries; and a culture of power and control. The findings suggest that moving family physicians toward more integrative and interdependent functioning within the primary care team will require overcoming the culture of traditional professional roles, addressing facilitators and barriers to teamwork, and providing training in teamwork.

The radiologic evaluation of Hirschsprung disease is well described in the literature. However, there is a paucity of literature describing the appearance of the neo-rectum and colon after repair, specifically describing findings in patients with poor functional outcome, which would suggest the need for reoperation. We describe findings on contrast enema and correlate them with surgical findings at reoperation in children with poor functional outcome after primary repair for Hirschsprung disease who suffer from bowel dysfunction that can manifest with either soiling or obstructive symptoms such as enterocolitis. Children were identified from our colorectal surgery database. At the time of abstract submission, 35 children had contrast enemas prior to reoperation. Additional children continue to present for evaluation. The majority of children included in the study had their primary repair performed elsewhere. The initial procedures included: Duhamel (n = 11), Soave (n = 20) or Swenson (n = 3). One child had undergone a primary Soave repair and subsequently had a Swenson-type reoperation but continued to have a poor outcome. One child's initial surgical repair could not be determined. Images were reviewed by a staff pediatric radiologist and a pediatric radiology fellow. Findings encountered on contrast enema in these children include a distal narrowed segment due to stricture or aganglionic/transitional zone segment (8), dilated/hypomotile distal segment (7), thickened presacral space due to compressing Soave cuff (11), dilated Duhamel pouch (8), active enterocolitis (3) and partially obstructing twist of the pull-through segment (1). Multiple anatomical and pathological complications exist that can lead to bowel dysfunction in children after repair of Hirschsprung disease. Little recent literature exists regarding the radiographic findings in children. We had the opportunity to review a substantial series of these children, describe the contrast enema findings in these difficult cases and correlate them with operative findings. Radiologic evaluation is key to assessing such patients; it defines the potential anatomical problem with the pull-through and facilitates surgical planning.

The study aimed to develop primary school science lesson plan based on inquiry cycle (5Es) through lesson study. The study focused on the development of 4 primary school science lesson plans of force and motion for Grade 3 students in KKU Demonstration Primary School (Suksasart), first semester of 2015 academic year. The methodology is mixed method. The Inthaprasitha (2010) lesson study cycle was implemented in group of KKU Demonstration Primary School. Instruments of reflection of lesson plan developing included participant observation, meeting and reflection report, lesson plan and other document. The instruments of examining students' learning include classroom observation and achievement test. Data was categorized from these instruments to find the issues of changing and improving the good lesson plan of Thai primary school science learning. The findings revealed that teachers could develop the lesson plans through lesson study. The issues of changing and improving were disused by considering on engaging students related to societal issues, students' prior knowledge, scientific concepts for primary school students, and what they learned from their changing. It indicated that the Lesson Study allowed primary school science teachers to share ideas and develop ideas to improve the lesson. The study may have implications for Thai science teacher education through Lesson Study.

Primary care research conducted in networks: getting down to business.
Mold, James W
2012-01-01
This seventh annual practice-based research theme issue of the Journal of the American Board of Family Medicine highlights primary care research conducted in practice-based research networks (PBRNs). The issue includes discussion of (1) theoretical and methodological research, (2) health care research (studies addressing primary care processes), (3) clinical research (studies addressing the impact of primary care on patients), and (4) health systems research (studies of health system issues impacting primary care including the quality improvement process). We had a noticeable increase in submissions from PBRN collaborations, that is, studies that involved multiple networks. As PBRNs cooperate to recruit larger and more diverse patient samples, greater generalizability and applicability of findings lead to improved primary care processes.

Increasing the attractiveness of primary care careers is a key step in addressing the growing shortage of primary care physicians. The purpose of this review was to (1) identify interventions aimed at increasing the proportion of undergraduate medical students choosing a primary care specialty, (2) describe the characteristics of these interventions, (3) assess the quality of the studies, and (4) compare the findings to those of a previous literature review within a global context. We searched MEDLINE, EMBASE, ERIC, CINAHL, PsycINFO, The Cochrane Library, and Dissertations & Theses A&I for articles published between 1993 and February 20, 2015. We included quantitative and qualitative studies reporting on primary care specialty choice outcomes of interventions in the undergraduate medical curriculum, without geographic restrictions. Data extracted included study characteristics, intervention details, and relevant outcomes. Studies were assessed for quality and strength of findings using a five-point scale. The review included 72 articles reporting on 66 different interventions. Longitudinal programs were the only intervention consistently associated with an increased proportion of students choosing primary care. Successful interventions were characterized by diverse teaching formats, student selection, and good-quality teaching. Study quality had not improved since recommendations were published in 1995. Many studies used cross-sectional designs and non-validated surveys, did not include control groups, and were not based on a theory or conceptual framework. Our review supports the value of longitudinal, multifaceted, primary care programs to increase the proportion of students choosing primary care specialties. Isolated modules or clerkships did not appear to be effective. Our results are in line with the conclusions from previous reviews and add an international perspective, but the evidence is limited by the overall low methodological quality of the included studies. Future research should use more rigorous evaluation methods and include long-term outcomes.

Prediction of primary vs secondary hypertension in children.
Baracco, Rossana; Kapur, Gaurav; Mattoo, Tej; Jain, Amrish; Valentini, Rudolph; Ahmed, Maheen; Thomas, Ronald
2012-05-01
Despite current guidelines, variability exists in the workup of hypertensive children due to physician preferences. The study evaluates primary vs secondary hypertension diagnosis from investigations routinely performed in hypertensive children. This retrospective study included children 5 to 19 years with primary and secondary hypertension. The proportions of abnormal laboratory and imaging tests were compared between primary and secondary hypertension groups. Risk factors for primary vs secondary hypertension were evaluated by logistic regression and likelihood function analysis. Patients with secondary hypertension were younger (5-12 years) and had a higher proportion of abnormal creatinine, renal ultrasound, and echocardiogram findings. There was no significant difference in abnormal results of thyroid function, urine catecholamines, plasma renin, and aldosterone. Abnormal renal ultrasound findings and age were predictors of secondary hypertension by regression and likelihood function analysis. Children aged 5 to 12 years with abnormal renal ultrasound findings and high diastolic blood pressures are at higher risk for secondary hypertension that requires detailed evaluation. © 2012 Wiley Periodicals, Inc.

Chinese perspectives on primary care for common mental disorders: Barriers and policy implications.
Sun, Kai Sing; Lam, Tai Pong; Wu, Dan
2018-05-01
The World Health Organization (WHO) has called for integration of mental health into primary care for a decade. In Western countries, around 15% to 25% of patients with common mental disorders including mood and anxiety disorders seek help from primary care physicians (PCPs). The rate is only about 5% in China. This article reviews the Chinese findings on the barriers to primary care for common mental disorders and how they compared with Western findings. A narrative literature review was conducted, focusing on literature published from mid-1990s in English or Chinese. Patient, PCP and health system factors were reviewed. Although Chinese and Western findings show similar themes of barriers, the Chinese have stronger barriers in most aspects, including under-recognition of the need for treatment, stigma on mental illness, somatization, worries about taking psychiatric drugs, uncertainties in the role, competency and legitimacy of PCPs in mental health care and short consultation time. Current policies in China emphasize enhancement of mental health facilities and workforce in the community. Our review suggests that patients' intention to seek help and PCPs' competency in mental health care are other fundamental factors to be addressed.

Barriers to primary care responsiveness to poverty as a risk factor for health.
Bloch, Gary; Rozmovits, Linda; Giambrone, Broden
2011-06-29
Poverty is widely recognized as a major determinant of poor health, and this link has been extensively studied and verified. Despite the strong evidentiary link, little work has been done to determine what primary care health providers can do to address their patients' income as a risk to their health. This qualitative study explores the barriers to primary care responsiveness to poverty as a health issue in a well-resourced jurisdiction with near-universal health care insurance coverage. One to one interviews were conducted with twelve experts on poverty and health in primary care in Ontario, Canada. Participants included family physicians, specialist physicians, nurse practitioners, community workers, advocates, policy experts and researchers. The interviews were analysed for anticipated and emergent themes. This study reveals provider- and patient-centred structural, attitudinal, and knowledge-based barriers to addressing poverty as a risk to health. While many of its findings reinforce previous work in this area, this study's findings point to a number of areas front line primary care providers could target to address their patients' poverty. These include a lack of provider understanding of the lived reality of poverty, leading to a failure to collect adequate data about patients' social circumstances, and to the development of inappropriate care plans. Participants also pointed to prejudicial attitudes among providers, a failure of primary care disciplines to incorporate approaches to poverty as a standard of care, and a lack of knowledge of concrete steps providers can take to address patients' poverty. While this study reinforces, in a well-resourced jurisdiction such as Ontario, the previously reported existence of significant barriers to addressing income as a health issue within primary care, the findings point to the possibility of front line primary care providers taking direct steps to address the health risks posed by poverty. The consistent direction and replicability of these findings point to a refocusing of the research agenda toward an examination of interventions to decrease the health impacts of poverty.

3D-TOF-MRA and DSA are 2 available tools to demonstrate neurovascular involvement in primary central nervous system vasculitis. We aimed to compare the diagnostic concordance of vessel imaging using 3D-TOF-MRA and DSA in patients with primary central nervous system vasculitis. We retrospectively identified all patients included in the French primary central nervous system vasculitis cohort of 85 patients who underwent, at baseline, both intracranial 3D-TOF-MRA and DSA in an interval of no more than 2 weeks and before treatment initiation. Two neuroradiologists independently reviewed all 3D-TOF-MRA and DSA imaging. Brain vasculature was divided into 25 arterial segments. Concordance between 3D-TOF-MRA and DSA for the identification of arterial stenosis was assessed by the Cohen κ Index. Thirty-one patients met the inclusion criteria, including 20 imaged with a 1.5T MR unit and 11 with a 3T MR unit. Among the 25 patients (81%) with abnormal DSA findings, 24 demonstrated abnormal 3D-TOF-MRA findings, whereas all 6 remaining patients with normal DSA findings had normal 3D-TOF-MRA findings. In the per-segment analysis, concordance between 1.5T 3D-TOF-MRA and DSA was 0.82 (95% CI, 0.75-0.93), and between 3T 3D-TOF-MRA and DSA, it was 0.87 (95% CI, 0.78-0.91). 3D-TOF-MRA shows a high concordance with DSA in diagnostic performance when analyzing brain vasculature in patients with primary central nervous system vasculitis. In patients with negative 3T 3D-TOF-MRA findings, the added diagnostic value of DSA is limited. © 2017 by American Journal of Neuroradiology.

The objective of this systematic review was to identify primary health-care or aged-care strategies that have or could support the well-being of older Indigenous peoples. A search was undertaken of primary databases including Medical Literature Analysis and Retrieval System Online and Cumulative Index to Nursing and Allied Health Literature. Papers which reported on the perspectives of older Indigenous peoples, community members and provider participants were included. Findings were pooled using a meta-aggregative approach. Three high-level synthesised findings - maintaining Indigenous identity, promoting independence and delivering culturally safe care - were believed to be important for supporting the well-being of older Indigenous peoples. As physical independence often diminishes with age, having the support of culturally safe primary health-care and aged-care services that understand the importance of maintaining an Indigenous identity and promoting independence will be crucial for the well-being of older Indigenous peoples. © 2016 AJA Inc.

Barriers to the Treatment of Mental Illness in Primary Care Clinics in Israel.
Ayalon, Liat; Karkabi, Khaled; Bleichman, Igor; Fleischmann, Silvia; Goldfracht, Margalit
2016-03-01
The present study examined physicians' perceived barriers to the management of mental illness in primary care settings in Israel. Seven focus groups that included a total of 52 primary care Israeli physicians were conducted. Open coding analysis was employed, consisting of constant comparisons within and across interviews. Three major themes emerged: (a) barriers to the management of mental illness at the individual-level, (b) barriers to the management of mental illness at the system-level, and (c) the emotional ramifications that these barriers have on physicians. The findings highlight the parallelism between the experiences of primary care physicians and their patients. The findings also stress the need to attend to physicians' emotional reactions when working with patients who suffer from mental illness and to better structure mental health treatment in primary care.

Researching primary engineering education: UK perspectives, an exploratory study
NASA Astrophysics Data System (ADS)
Clark, Robin; Andrews, Jane
2010-10-01
This paper draws attention to the findings of an exploratory study that critically identified and analysed relevant perceptions of elementary level engineering education within the UK. Utilising an approach based upon grounded theory methodology, 30 participants including teachers, representatives of government bodies and non-profit providers of primary level engineering initiatives were interviewed. Three main concepts were identified during the analysis of findings, each relevant to primary engineering education. These were pedagogic issues, exposure to engineering within the curriculum and children's interest. The paper concludes that the opportunity to make a real difference to children's education by stimulating their engineering imagination suggests this subject area is of particular value.

Background Systematic reviews provide clinical practice recommendations that are based on evaluation of primary evidence. When systematic reviews with the same aims have different conclusions, it is difficult to ascertain which review reported the most credible and robust findings. Methods This study examined five systematic reviews that have investigated the effectiveness of Pilates exercise in people with chronic low back pain. A four-stage process was used to interpret findings of the reviews. This process included comparison of research questions, included primary studies, and the level and quality of evidence of systematic reviews. Two independent reviewers assessed the level of evidence and the methodological quality of systematic reviews, using the National Health and Medical Research Council hierarchy of evidence, and the Revised Assessment of Multiple Systematic Reviews respectively. Any disagreements were resolved by a third researcher. Results A high level of consensus was achieved between the reviewers. Conflicting findings were reported by the five systematic reviews regarding the effectiveness of Pilates in reducing pain and disability in people with chronic low back pain. Authors of the systematic reviews included primary studies that did not match their questions in relation to treatment or population characteristics. A total of ten primary studies were identified across five systematic reviews. Only two of the primary studies were included in all of the reviews due to different inclusion criteria relating to publication date and status, definition of Pilates, and methodological quality. The level of evidence of reviews was low due to the methodological design of the primary studies. The methodological quality of reviews varied. Those which conducted a meta-analysis obtained higher scores. Conclusion There is inconclusive evidence that Pilates is effective in reducing pain and disability in people with chronic low back pain. This is due to the small number and poor methodological quality of primary studies. The Revised Assessment of Multiple Systematic Reviews provides a useful method of appraising the methodological quality of systematic reviews. Individual item scores, however, should be examined in addition to total scores, so that significant methodological flaws of systematic reviews are not missed, and results are interpreted appropriately.

We assessed the plain radiographic characteristics of 10 cases of osteosarcomas during the initial painful period that had been overlooked by a primary physician. In addition, we evaluated chronologic changes in radiographic findings from initial symptomatic period to the time of accurate diagnosis. The clinical records were reviewed for clinical parameters including age, sex, location, presenting symptoms, initial diagnosis, duration from initial symptoms to definite diagnosis, and initial and follow-up plain radiographic findings of the lesion. Initial clinical diagnoses included a sprain in 6, growing pain in 2, stress fracture in 1, and infection in 1 patient. Initial plain radiographic findings were trabecular destruction (100%), cortical disruption (60%), periosteal reaction (60%), and soft tissue mass (10%). Intramedullary matrix changes were osteosclerosis in 6 and osteolysis in 4 patients. On progression, 4 cases with minimal sclerosis changed to osteoblastic lesion in 3 patients and osteolytic lesion in 1. Four cases with faint osteolytic foci transformed into osteolytic lesion in 3 and mixed pattern in 1. Notable plain radiologic findings of incipient-stage osteosarcoma include trabecular disruption along with faint osteosclerosis or osteolysis. In symptomatic patients with trabecular destruction, additional imaging study including magnetic resonance imaging should be performed to exclude osteosarcoma in the incipient phase, even without radiologic findings suggesting malignant tumor, such as cortical destruction or periosteal reaction.

Adenoid cystic carcinoma is a very rare primary pulmonary neoplasm. Cytologic findings of pulmonary washing and brushing in 2 cases of primary bronchial adenoid cystic carcinoma with special histologic features are described, with an emphasis on some points that have not been reported previously, together with the diagnostic pitfalls. Two cases of primary adenoid cystic carcinoma of the lung were diagnosed on exfoliative cytology. The patients' ages were 55 and 65 years old. Cytologic findings included large and small clusters of small cells in both 2 and 3 dimensions with occasional cystlike spaces containing mucoid material. The cells were arranged in spherical, cylindrical, basaloid and rosettelike arrangements. There were also abundant small and large mucoid globules, cylinders of homogeneous, acellular, mucous material and "cannon balls." Cytoplasmic and intranuclear round inclusions were noted in case 1. Rare findings of nuclear molding were noted. In case 2, chondromyxoid material and a bimorphic population of tumor cells caused diagnostic confusion with other salivary gland-type tumors of the lung. These cases showed characteristic cytologic findings of adenoid cystic carcinoma together with rare findings of intracellular and extracellular inclusionlike bodies, myxochondroid material, bimorphic populations and nuclear molding, which can cause diagnostic confusion with other lung tumors.

During the last decade, teamwork has been addressed under the rationale of interprofessional practice or collaboration, highlighted by the attributes of this practice such as: interdependence of professional actions, focus on user needs, negotiation between professionals, shared decision making, mutual respect and trust among professionals, and acknowledgment of the role and work of the different professional groups. Teamwork and interprofessional collaboration have been pointed out as astrategy for effective organization of health care services as the complexity of healthcare requires integration of knowledge and practices from differente professional groups. This integration has a qualitative dimension that can be identified through the experiences of health professionals and to the meaning they give to teamwork. The objective of this systematic review was to synthesize the best available evidence on the experiences of health professionals regarding teamwork and interprofessional collaboration in primary health care settings. The populations included were all officially regulated health professionals that work in primary health settings: dentistry, medicine, midwifery, nursing, nutrition, occupational therapy, pharmacy, physical education, physiotherapy, psychology, social work and speech therapy. In addition to these professionals, community health workers, nursing assistants, licensed practical nurses and other allied health workers were also included. The phenomena of interest were experiences of health professionals regarding teamwork and interprofessional collaboration in primary health care settings. The context was primary health care settings that included health care centers, health maintenance organizations, integrative medicine practices, integrative health care, family practices, primary care organizations and family medical clinics. National health surgery as a setting was excluded. The qualitative component of the review considered studies that focused on qualitative data including designs such as phenomenology, grounded theory, ethnography, action research and feminist research. A three-step search strategy was utilized. Ten databases were searched for papers published from 1980 to June 2015. Studies published in English, Portuguese and Spanish were considered. Methodological quality was assessed using the Qualitative Assessment and Review Instrument developed by the Joanna Briggs Institute. All included studies received a score of at least 70% the questions in the instrument, 11 studies did not address the influence of the researcher on the research or vice-versa, and six studies did not present a statement locating the researcher culturally or theoretically. Qualitative findings were extracted using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Qualitative research findings were pooled using a pragmatic meta-aggregative approach and the Joanna Briggs Institute Qualitative Assessment and Review Instrument software. This review included 21 research studies, representing various countries and healthcare settings. There were 223 findings, which were aggregated into 15 categories, and three synthesized findings: CONCLUSIONS: This review shows that health professionals experience teamwork and interprofessional collaboration as a process in primary health care settings; its conditions, consequences (benefits and barriers), and finally shows its determinants. Health providers face enormous ideological, organizational, structural and relational challenges while promoting teamwork and interprofessional collaboration in primary health care settings. This review has identified possible actions that could improve implementation of teamwork and interprofessional collaboration in primary health care.

The computed tomography (CT) findings of ovarian metastases from colon cancer were evaluated and were compared with those of primary malignant ovarian tumors. Sixteen patients with 21 masses from colon cancer and 20 patients with 31 primary malignant ovarian tumors were included in this study. The CT findings (laterality, size, margin, shape, mass characteristic, strong enhancement of cyst wall, enhancement of solid portion, amount of ascites, peritoneal seeding, lymph node enlargement, and metastasis) and ages of the patients in both groups were compared. Univariate analysis, the Pearson chi test, and the independent-samples t test were used to distinguish them. A smooth margin of the tumor (odds ratio=24.3, 95% confidence interval: 2.9-204.2) and cystic nature of the mass (Pearson chi=12.96, P=0.005) were strong predictors of ovarian metastasis from colon cancer. Ovarian metastases from colon cancer show a smooth margin and more cystic nature on CT compared with primary malignant ovarian tumors.

Extreme drought is increasing globally in frequency and intensity, with uncertain consequences for the resistance and resilience of key ecosystem functions, including primary production. Primary production resistance, the capacity of an ecosystem to withstand change in primary production following extreme climate, and resilience, the degree to which primary production recovers, vary among and within ecosystem types, obscuring global patterns of resistance and resilience to extreme drought. Past syntheses on resistance have focused climatic gradients or individual ecosystem types, without assessing interactions between the two. Theory and many empirical studies suggest that forest production is more resistant but less resilient than grassland production to extreme drought, though some empirical studies reveal that these trends are not universal. Here, we conducted a global meta-analysis of sixty-four grassland and forest sites, finding that primary production resistance to extreme drought is predicted by a common continuum of mean annual precipitation (MAP). However, grasslands and forests exhibit divergent production resilience relationships with MAP. We discuss the likely mechanisms underlying the mixed production resistance and resilience patterns of forests and grasslands, including different plant species turnover times and drought adaptive strategies. These findings demonstrate the primary production responses of forests and grasslands to extreme drought are mixed, with far-reaching implications for Earth System Models, ecosystem management, and future studies of extreme drought resistance and resilience.

Severe hyponatraemia in foals: clinical findings, primary diagnosis and outcome.
Collins, N M; Axon, J E; Carrick, J B; Russell, C M; Palmer, J E
2016-06-01
To evaluate severe hyponatraemia in foals presenting as medical emergencies to an intensive care unit (ICU) in order to determine the prevalence, clinical findings, primary diagnosis and outcome. Retrospective case study of records from Thoroughbred foals aged less than 3 months presenting to an ICU as medical emergencies in 2002-12; foals with severe hyponatraemia (serum sodium <122 mmol/L) on admission laboratory data were identified. Data retrieved included signalment, clinical findings, laboratory results, primary diagnosis, treatment and outcome. Severe hyponatraemia was identified in 69/1718 Thoroughbred foals (4%) presenting to the ICU during the study period. Of the 69 foals, 11 (15.9%) presented with neurological signs attributable to hyponatraemic encephalopathy and 7 of these foals had seizures; other neurological signs included obtundation, ataxia and apparent blindness. The three most common primary diagnoses of the 69 foals with severe hyponatraemia were renal disease (18/69, 26.1%), enterocolitis (16/69, 23.2%) and uroperitoneum (15/69, 21.7%). Treatment was directed at the primary disease and correction of the hyponatraemia. A total of 50 of the 69 foals (72.5%) with severe hyponatraemia survived to hospital discharge and 38 of them (76%) survived at least 12 months following discharge. The prevalence of severe hyponatraemia in this study population was 4%. The majority of foals with severe hyponatraemia did not demonstrate direct clinical manifestations as a result of the low serum sodium concentration. The outcome of foals with severe hyponatraemia was mostly favourable. © 2016 Australian Veterinary Association.

Tridimensional endoanal ultrasonography (3D-EAUS) has been used for the assessment of various anorectal lesions. Previous studies have reported good accuracy of 3D-EAUS in preoperative assessment of fistula-in-ano (FIA). This study aimed to assess the diagnostic utility of 3D-EAUS in preoperative evaluation of primary and recurrent FIA and its role in detection of associated anal sphincter (AS) defects. Prospectively collected data of patients with FIA who were investigated with 3D-EAUS were reviewed. The findings of EAUS were compared with the intraoperative findings, the reference standard, to find the degree of agreement regarding the position of the internal opening (IO) and primary tract (PT), and presence of secondary tracts using kappa (k) coefficient test. A subgroup analysis was performed to compare the accuracy and sensitivity of EAUS for primary and recurrent FIA. Of the patients, 131 were included to the study. EAUS had an overall accuracy of 87, 88.5, and 89.5% in detection of IO, PT, and AS defects, respectively. There was very good concordance between the findings of EAUS and intraoperative findings for the investigated parameters (kappa = 0.748, 0.83, 0.935), respectively. Accuracy and sensitivity of EAUS in recurrent FIA were insignificantly lower than primary cases. EAUS detected occult AS defects in 5.3% of the patients studied. The diagnostic utility of 3D-EAUS was comparable in primary and recurrent FIA. 3D-EAUS was able to detect symptomatic and occult AS defects with higher accuracy than clinical examination.

To find out different causes of female infertility with diagnostic laparoscopy and their comparative frequency in primary and secondary infertility. A case series. Department of Obstetric and Gynaecology, Liaquat University Hospital (LUH), Hyderabad, rom January 2006 to December 2007. All infertile women underwent diagnostic laparoscopy for primary and secondary infertility during the study period were included. Couples who had not lived together for at least 12 months, and those with male factor infertility were excluded. Data were collected on a proforma, and analysed on SPSS package for windows version 10. Frequencies were calculated for laparoscopic findings regarding primary and secondary infertility. Fifty infertile women underwent laparoscopy during the study period, 32 (64%) had primary infertility while 18 (36%) secondary infertility. Eight (25.0%) patients with primary and 2 (11.1%) patients with secondary infertility had no visible abnormality. The common finding was tubal blockage in 7 (21.9%) and 6 (33.3%) cases of primary and secondary infertility respectively. Five (15.6%) cases of primary infertility were detected as polycystic ovaries (PCO) which was not found in cases of secondary infertility. Endometriosis was found in 4 (12.5%) cases with primary infertility and 2 (11.1%) cases with secondary infertility. Pelvic inflammatory disease (PID) was found in 1 (3.1%) and 2 (16.7%) cases of primary and secondary infertility respectively. Peritubal and periovarian adhesions were detected in 2 (6.3%) cases with primary infertility and 4 (22.2%) cases with secondary infertility. Fibriod was found in 2 (6.3%) and 1 (5.6%) cases of primary and secondary infertility respectively. Ovarian cyst detected in 2 (6.3%) cases with primary infertility while none was found in cases of secondary infertility. Most common causes responsible for infertility were tubal occlusion, endometriosis, peritubal and periovarian adhesions. Ovarian causes were seen in primary infertility only.

2011-03-01
In this article, we discuss findings from an ethnographic study in which we explored experiences of access to primary care services from the perspective of Aboriginal people seeking care at an emergency department (ED) located in a large Canadian city. Data were collected over 20 months of immersion in the ED, and included participant observation and in-depth interviews with 44 patients triaged as stable and nonurgent, most of whom were living in poverty and residing in the inner city. Three themes in the findings are discussed: (a) anticipating providers' assumptions; (b) seeking help for chronic pain; and (c) use of the ED as a reflection of social suffering. Implications of these findings are discussed in relation to the role of the ED as well as the broader primary care sector in responding to the needs of patients affected by poverty, racialization, and other forms of disadvantage.

We report on a longitudinal study designed to assess possible sex differences in math achievement, math ability, and math-related tasks during the primary school age years. Participants included over 200 children from one public school district. Annual assessments included measures of math ability, math calculation achievement scores, rapid naming and decoding tasks, visual perception tests, visual motor tasks, and reading skills. During select years of the study we also administered tests of counting and math facts skills. We examined whether girls or boys were overrepresented among the bottom or top performers on any of these tasks, relative to their peers, and whether growth rates or predictors of math-related skills differed for boys and girls. Our findings support the notion that sex differences in math are minimal or nonexistent on standardized psychometric tests routinely given in assessments of primary school age children. There was no persistent finding suggesting a male or female advantage in math performance overall, during any single year of the study, or in any one area of math or spatial skills. Growth rates for all skills, and early correlates of later math performance, were comparable for boys and girls. The findings fail to support either persistent or emerging sex differences on non-specialized math ability measures during the primary school age years. PMID:20463851

Emergency admission risk prediction models are increasingly used to identify patients, typically with one or more chronic conditions, for proactive management in primary care to avoid admissions, save costs and improve patient experience. To identify and review the published evidence on the costs, effects and implementation of emergency admission risk prediction models in primary care for patients with, or at risk of, chronic conditions. We shall search for studies of healthcare interventions using routine data-generated emergency admission risk models. We shall report: the effects on emergency admissions and health costs; clinician and patient views; and implementation findings. We shall search ASSIA, CINAHL, the Cochrane Library, HMIC, ISI Web of Science, MEDLINE and Scopus from 2005, review references in and citations of included articles, search key journals and contact experts. Study selection, data extraction and quality assessment will be performed by two independent reviewers. No ethical permissions are required for this study using published data. Findings will be disseminated widely, including publication in a peer-reviewed journal and through conferences in primary and emergency care and chronic conditions. We judge our results will help a wide audience including primary care practitioners and commissioners, and policymakers. CRD42015016874; Pre-results. Published by the BMJ Publishing Group Limited.

Clinical managers in the primary care sector: do the benefits stack up?
O'Riordan, Chris; McDermott, Aoife
2012-01-01
The purpose of this paper is to explore the nature and value of the clinical management role undertaken by primary care doctors in Ireland. To date, a majority of research has focused on clinical management roles in the acute sector. The paper presents a sub-set of data from a mixed methods study. In total, 14 semi-structured interviews are drawn upon to identify the nature and value of the clinical management role in primary care. Comparison with acute sector research identifies considerable differences in the nature of the clinical management role across sectors--and in the associated value proposition. Structural and role-related contingencies affecting the potential value of clinical management roles in Irish primary care are discussed. Structural influences include the private ownership structure, low complexity and limited requirement for cross-professional coordination. Role-related influences include the primacy of the clinical identity, time constraints and lack of managerial training. The findings provide a limited basis for generalisation, premised on 14 interviews in one national context. However, given the international shift towards the provision of health services in primary care, they provide a research agenda for an important healthcare context. The findings draw attention to the need for policy consideration of the value of the clinical manager role in primary care; how policy can support effective primary care management; and the need for specialised management training, which takes account of the small-firm context. The paper identifies that primary-care clinical-management roles focus on operational management and oversight and discusses the structural and role-related factors which affect their efficacy.

Canine soft tissue sarcomas (STS), primary brain tumours and intranasal tumours are commonly treated with radiotherapy (RT). Given the low metastatic potential of these tumours, recommendations regarding imaging tests as staging are variable among institutions. The purpose of our study was to describe thoracic radiographic and abdominal ultrasonographic findings in dogs with these neoplasms and to investigate association of abnormal findings with alterations in recommended treatment. Medical records from 101 dogs, each having thoracic radiographs and abdominal ultrasound performed as part of their staging, were reviewed. In 98 of 101 (97%), imaging abnormalities were detected, 27% of which were further investigated with fine needle aspiration cytology or biopsy. Nine percent of the detected abnormalities were considered serious comorbidities that altered treatment recommendations, including 3 (3%) which were confirmed as synchronous primary neoplasms. These findings may influence recommendations regarding the decision to perform thoracic radiographs and abdominal ultrasound prior to initiation of RT. © 2013 John Wiley & Sons Ltd.

The purpose of this study was to examine the challenges of integrating an asthma disease management (DM) program into a primary care setting from the perspective of primary care practitioners. A second goal was to examine whether barriers differed between urban-based and nonurban-based practices. Using a qualitative design, data were gathered using focus groups in primary care pediatric practices. A purposeful sample included an equal number of urban and nonurban practices. Participants represented all levels in the practice setting. Important themes that emerged from the data were coded and categorized. A total of 151 individuals, including physicians, advanced practice clinicians, registered nurses, other medical staff, and nonmedical staff participated in 16 focus groups that included 8 urban and 8 nonurban practices. Content analyses identified 4 primary factors influencing the implementation of a DM program in a primary care setting. They were related to providers, the organization, patients, and characteristics of the DM program. This study illustrates the complexity of the primary care environment and the challenge of changing practice in these settings. The results of this study identified areas in a primary care setting that influence the adoption of a DM program. These findings can assist in identifying effective strategies to change clinical behavior in primary care practices.

[Differences and similarities of primary care in the German and Spanish health care systems].
Salvador Comino, María Rosa; Krane, Sibylla; Schelling, Jörg; Regife García, Víctor

An efficient primary care is of particular importance for any countries' health care system. Many differences exist on how distinctive countries try to obtain the goal of an efficient, cost-effective primary care for its population. In this article we conducted a selective literature review, which includes both scientific and socio-political publications. The findings are complemented with the experience of a Spanish physician from Seville in her last year of training in family medicine, who completed a four months long rotation in the German health care system. We highlighted different features by comparing both countries, including their health care expenditure, the relation between primary and secondary care, the organization in the academic field and the training of future primary care physicians. It is clear that primary care in both countries plays a central role, have to deal with shortcomings, and in some points one system can learn from the other. Copyright © 2015 Elsevier España, S.L.U.

The Mouse Genetics Project (MGP) at the Wellcome Trust Sanger Institute aims to generate and phenotype over 800 genetically modified mouse lines over the next 5 years to gain a better understanding of mammalian gene function and provide an invaluable resource to the scientific community for follow-up studies. Phenotyping includes the generation of a standardized biobank of paraffin-embedded tissues for each mouse line, but histopathology is not routinely performed. In collaboration with the Pathology Core of the Centre for Modeling Human Disease (CMHD) we report the utility of histopathology in a high-throughput primary phenotyping screen. Histopathology was assessed in an unbiased selection of 50 mouse lines with (n=30) or without (n=20) clinical phenotypes detected by the standard MGP primary phenotyping screen. Our findings revealed that histopathology added correlating morphological data in 19 of 30 lines (63.3%) in which the primary screen detected a phenotype. In addition, seven of the 50 lines (14%) presented significant histopathology findings that were not associated with or predicted by the standard primary screen. Three of these seven lines had no clinical phenotype detected by the standard primary screen. Incidental and strain-associated background lesions were present in all mutant lines with good concordance to wild-type controls. These findings demonstrate the complementary and unique contribution of histopathology to high-throughput primary phenotyping of mutant mice. PMID:24652767

Primary healthcare researchers are under increasing pressure to demonstrate measurable and lasting improvement in clinical practice and healthcare policy as a result of their work. It is therefore important to understand the effectiveness of the research dissemination strategies used. The aim of this paper is to describe the pathways for research impact that have been achieved across several government-funded primary healthcare projects, and the effectiveness of these methods as perceived by their Chief Investigators. The project used an online survey to collect information about government-funded primary healthcare research projects. Chief Investigators were asked how they disseminated their findings and how this achieved impact in policy and practice. They were also asked to express their beliefs regarding the most effective means of achieving research impact and describe how this occurred. Chief Investigators of 17 projects indicated that a number of dissemination strategies were used but that professional networks were the most effective means of promoting uptake of their research findings. Utilisation of research findings for clinical practice was most likely to occur in organisations or among individual practitioners who were most closely associated with the research team, or when research findings were included in educational programmes involving clinical practice. Uptake of both policy- and practice-related research was deemed most successful if intermediary organisations such as formal professional networks were engaged in the research. Successful primary healthcare researchers had developed critical relationships with intermediary organisations within primary healthcare before the initiation of the research and had also involved them in the design. The scale of research impact was influenced by the current policy environment, the type and significance of the results, and the endorsement (or lack thereof) of professional bodies. Chief Investigators believed that networks were the most effective means of research dissemination. Researchers who were embedded in professional, clinical or policy-focussed intermediary organisations, or had developed partnerships with clinical services, which had a vested interest in the research findings, were more able to describe a direct impact of their research. This suggests that development of these relationships and engagement of these stakeholders by primary healthcare researchers is a vital step for optimal research utilisation in the primary healthcare setting.

Concern in patients with bladder exstrophy after reconstruction regarding potential injury to pelvic neurourological anatomy and a resultant functional deficit prompted combined (simultaneous) cystometrography and electromyography after complete primary repair of bladder exstrophy. We determined whether complete primary repair of bladder exstrophy would adversely affect the innervation controlling bladder and external urethral sphincter function. Complete primary repair of bladder exstrophy was performed via a modified Mitchell technique in newborns without osteotomy. Postoperative evaluation included combined cystometrography and needle electrode electromyography via the perineum, approximating the external urethral sphincter muscle complex. Electromyography was done to evaluate the external urethral sphincter response to sacral reflex stimulation and during voiding. Nine boys and 4 girls underwent combined cystometrography/electromyography after complete primary repair of bladder exstrophy. Age at study and time after complete primary repair of bladder exstrophy was 3 months to 10 years (median 11.5 months). Cystometrography revealed absent detrusor overactivity and the presence of a sustained detrusor voiding contraction in all cases. Electromyography showed universally normal individual motor unit action potentials of biphasic pattern, amplitude and duration. The external urethral sphincter sacral reflex response was intact with a normal caliber with respect to Valsalva, Credé, bulbocavernosus and anocutaneous (bilateral) stimulation. Synergy was documented by abrupt silencing of external urethral sphincter electromyography activity during voiding. After complete primary repair of bladder exstrophy combined cystometrography/electromyography in patients with bladder exstrophy showed normal neurourological findings, including sacral reflex responses, sustained detrusor voiding contraction and synergic voiding, in all patients postoperatively. These findings confirm the safety of complete primary repair of bladder exstrophy. Based on our results we have discontinued routine electromyography in these patients.

Interprofessional online learning for primary healthcare: findings from a scoping review
Reeves, Scott; Fletcher, Simon; McLoughlin, Clodagh; Yim, Alastair; Patel, Kunal D
2017-01-01
Objectives This article presents the findings from a scoping review which explored the nature of interprofessional online learning in primary healthcare. The review was informed by the following questions: What is the nature of evidence on online postgraduate education for primary healthcare interprofessional teams? What learning approaches and study methods are used in this context? What is the range of reported outcomes for primary healthcare learners, their organisations and the care they deliver to patients/clients? Setting The review explored the global literature on interprofessional online learning in primary healthcare settings. Results The review found that the 23 included studies employed a range of different e-learning methods with contrasting course durations, use of theory, participant mix, approaches to accreditation and assessment of learning. Most of the included studies reported outcomes associated with learner reactions and positive changes in participant attitudes/perceptions and improvement in knowledge/skills as a result of engagement in an e-learning course. In contrast, fewer studies reported changes in participant behaviours, changes in organisational practice and improvements to patients/clients. Conclusions A number of educational, methodological and outcome implications are be offered. E-learning can enhance an education experience, support development, ease time constraints, overcome geographic limitations and can offer greater flexibility. However, it can also contribute to the isolation of learners and its benefits can be negated by technical problems. PMID:28780560

This study reviewed the use in primary care of national surveillance data for children to determine the data's potential utility to inform policy and practice decisions on how to prevent and treat childhood obesity. We reviewed the 28 countries identified by the World Obesity Federation as having high-quality comparable body mass index data for children. Literature published from any period up to December 2013 was included. Peer review literature was searched using Web of Science (Core Collection, MEDLINE). Grey literature was searched using the Internet by country name, programme name and national health and government websites. We included studies that (i) use national surveillance obesity data in primary care, or (ii) explore practitioner or parent perspectives about the use of such data. The main uses of national surveillance data in primary care were to identify and recruit obese children and their parents to participate in school and general practice-based research and/or interventions, and to inform families of children's measurements. Findings indicate a need for school staff and practitioners to receive additional training and support to sensitively communicate with families. Translation of these findings into policy and practice could help to improve current uses of national child obesity surveillance data in primary care. © 2015 The Authors.

Examine whether children with a primary diagnosis of generalized anxiety disorder (GAD) differ from children with a secondary diagnosis of GAD on clinician, parent, teacher, and youth-report measures. Based on consensus diagnoses, 64 youth referred to a general outpatient assessment clinic were categorized as having either a primary or secondary diagnosis of GAD. A semi-structured diagnostic interview was used to guide diagnostic decisions and assign primary versus secondary diagnostic status. We predicted that youth with a primary GAD diagnosis would present with greater anxiety symptomatology and symptom impairment on a variety of anxiety-related measures than youth with a secondary GAD diagnosis. Contrary to our hypotheses, no differences were found between those with primary versus secondary GAD diagnoses on measures of symptom severity and clinical impairment, comorbid diagnoses, or youth and teacher-report measures. Our findings have potential implications for the current practice of requiring primary anxiety diagnostic status as an inclusion criterion in clinical research and treatment outcome studies. Assuming our findings are confirmed in larger samples and with other anxiety disorders, future clinical trials and basic psychopathology research might not exclude youth based on absence of a particular anxiety disorder as the primary disorder but rather include individuals for whom that anxiety disorder is secondary as well.

This study explores the perceived barriers to primary health care as identified among a sample of Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) identified individuals and health care providers in Nova Scotia, Canada. These findings, based on a province-wide anonymous online survey, suggest that additional efforts are needed to improve pathways to primary health among LGBTQ populations and in deepening our understanding of how to advance the unique primary health needs of these populations. Data were collected from the LGBTQ community through an online, closed-ended anonymous survey. Inclusion criteria for participation were self-identifying as LGBTQ, offering primary health care to LGBTQ patients, being able to understand English, being 16 years of age or older, and having lived in Nova Scotia for at least one year. A total of 283 LGBTQ respondents completed the online survey which included sociodemographic questions, perceptions of respondents' health status, and their primary health care experiences. In addition, a total of 109 health care providers completed the survey based on their experiences providing care in Nova Scotia, and in particular, their experiences and perceptions regarding LGBTQ access to primary health care and physician-patient interactions. Our results indicate that, in several key areas, the primary health care needs of LGBTQ populations in Nova Scotia are not being met and this may in turn contribute to their poor health outcomes across the life course. A framework of intersectionality and health equity was used to interpret and analyze the survey data. The key findings indicate the need to continue improving pathways to primary health care among LGBTQ populations, specifically in relation to additional training and related supports for health care providers who work with these populations.

Primary bone marrow oedema syndromes.
Patel, Sanjeev
2014-05-01
MRI scanning in patients with rheumatological conditions often shows bone marrow oedema, which can be secondary to inflammatory, degenerative, infective or malignant conditions but can also be primary. The latter condition is of uncertain aetiology and it is also uncertain whether it represents a stage in the progression to osteonecrosis in some patients. Patients with primary bone marrow oedema usually have lower limb pain, commonly the hip, knee, ankle or feet. The diagnosis is one of exclusion with the presence of typical MRI findings. Treatment is usually conservative and includes analgesics and staying off the affected limb. The natural history is that of gradual resolution of symptoms over a number of months. Evidence for medical treatment is limited, but open-label studies suggest bisphosphonates may help in the resolution of pain and improve radiological findings. Surgical decompression is usually used as a last resort.

Considerable expectations have been placed on information and communication technology (ICT) in improving the processes and quality of healthcare. Our purpose was to find out which element is found positive in healthcare ICT implementation. An online questionnaire on e-Health implementation submitted to all Finnish public health service providers and a sample from the private sector included an open question about which the electronic working methods, systems, or applications have most positively influenced the fluency or quality of service processes. The electronic health record was mentioned as an item that has positive influence by 52% of the respondents from the hospital districts, 27% of those from the primary healthcare centers, and 38% of those from the private providers. Digital radiology systems (including teleradiology) were mentioned by 52% of the hospital districts and 27% of the primary healthcare centers. The figures for digital laboratory systems (including telelaboratory) were 5% and 11%, respectively. The figures for teleradiology itself were 5% for the hospital districts and 15% for the primary healthcare centers; the figures for telelaboratory systems were 5% and 9%, respectively. The specialized healthcare seem to experience intraorganizational electronic services integrated to the electronic health record, such as digital radiology and laboratory services as exerting a positive influence, whereas the primary healthcare find such influence from different functions such as interorganizational data exchange and telemedicine services. These might indicate where the efforts should be focused when implementing ICT in healthcare.

Increasing interest has been shown in shared decision making (SDM) to improve mental health care communication between underserved immigrant minorities and their providers. Nonetheless, very little is known about this process. The following is a qualitative study of fifteen primary care providers at two Federally Qualified Health Centers in New York and their experience during depression treatment decision making. Respondents described a process characterized in between shared and paternalistic models of treatment decision making. Barriers to SDM included discordant models of illness, stigma, varying role expectations and decision readiness. Respondents reported strategies used to overcome barriers including understanding illness perceptions and the role of the community in the treatment process, dispelling stigma using cultural terms, orienting patients to treatment and remaining available regarding the treatment decision. Findings from this study have implications for planning SDM interventions to guide primary care providers through treatment engagement for depression.

Zhang, J J; Yang, X T; Du, X S; Zhang, J X; Hou, L N; Niu, J L
2018-01-23
Objective: To investigate the magnetic resonance imaging (MRI) findings and clinicopathological features of primary lesions in patients with occult breast cancer (OBC). Methods: The imaging reports from the Breast Imaging Reporting and Data System in 2013 were retrospectively analyzed to investigate the morphology and the time signal intensity curve (TIC) of breast lesions in patients with OBC. The clinical and pathological characteristics of these patients were also included. Results: A total of 34 patients were enrolled. Among these patients, 24 patients underwent modified radical mastectomy and 18 of them had primary breast carcinoma in pathological sections. MRI detected 17 cases of primary lesions, including six masse lesions with a diameter of 0.6-1.2 cm (average 0.9 cm), and 11 non-mass lesions with four linear distributions, three segmental distributions, three focal distributions, and one regions distribution. Five patients had TIC typeⅠprimary lesions, ten had TIC type Ⅱ primary lesions, and two had TIC type Ⅲ primary lesions. Among all 34 cases, 23 of them had complete results of immunohistochemistry: 11 estrogen receptor (ER) positive lesions (47.8%), tenprogesterone receptor (PR) positive lesions (43.5%), seven human epidermal growth factor receptor 2 (HER-2) positive lesions (30.4%), and 20high expression(>14%) of Ki-67 (87.0%). The proportion of type luminal A was 4.3%, type luminal B was 43.5%, triple negative breast cancer (TNBC) was 30.4%, and HER-2 over expression accounted for 21.7%. Conclusions: The primary lesions of OBC usually manifested as small mass lesions, or focal, linear or segmental distribution of non-mass lesions. The positive rate of ER and PR was low, but the positive rate of HER-2 and the proliferation index of Ki-67 was high. Type luminal B is the most common molecular subtype.

A little thing called love: Condom use among high-risk primary heterosexual couples
Corbett, A. Michelle; Dickson-Gómez, Julia; Hilario, Helena; Weeks, Margaret R.
2010-01-01
Introduction Research shows that condoms are least likely to be used in primary relationships. A deeper understanding of the expectations women and men hold when entering into these relationships, as well as how decisions related to condom use and other prevention behaviors are made, is essential if we are to curb the spread of HIV. Methodology Qualitative in-depth interviews were conducted with 25 high-risk heterosexual couples, including HIV sero-discordant couples, in Hartford, CT. Qualitative data were coded and analyzed in an iterative inductive and deductive process using Atlas.ti. Results Participants employed non-use of condoms as a strategy to find and maintain a primary relationship, establish trust and increase intimacy. Many did so while recognizing their risk of HIV/STI illustrating the importance of love and the other emotional needs primary relationships satisfy. Second, several couples described practicing negotiated safety or similar strategies as a way to minimize their HIV/STI risk. These strategies varied in potential effectiveness and included sharing sexual and/or drug use history, disclosure of prior HIV test results, and using condoms until it was decided that this was a monogamous relationship, among others. Discussion Findings suggest that men and women may choose not to use condoms as they pursue and attempt to maintain a primary relationship. HIV prevention approaches must recognize the importance of love and the needs primary relationships satisfy if they are to be considered relevant by those at greatest risk. Negotiated safety may be an important risk reduction tool for heterosexuals, particularly those in HIV-affected relationships. PMID:20444176

Synopsis Primary lateral sclerosis (PLS) is characterized by insidious onset of progressive upper motor neuron dysfunction in the absence of clinical signs of lower motor neuron involvement. Patients experience stiffness, decreased balance and coordination, and mild weakness, and if the bulbar region is affected, difficulty speaking and swallowing, and emotional lability. The diagnosis is made based on clinical history, typical exam findings, and diagnostic testing negative for other causes of upper motor neuron dysfunction. EMG is normal, or only shows mild neurogenic findings in a few muscles, not meeting El Escorial criteria. Although no test is specific for PLS, some neurodiagnostic tests are supportive: including absent or delayed central motor conduction times; and changes in the precentral gyrus or corticospinal tracts on MRI, DTI or MR Spectroscopy. Treatment is largely supportive, and includes medications for spasticity, baclofen pump, and treatment for pseudobulbar affect. The prognosis in PLS is more benign than ALS, making this a useful diagnostic category. PMID:26515619

Research based on functional imaging and neuronal recordings in the barrel cortex subdivision of primary somatosensory cortex (SI) of the adult rat has revealed novel aspects of structure-function relationships in this cortex. Specifically, it has demonstrated that single whisker stimulation evokes subthreshold neuronal activity that spreads symmetrically within gray matter from the appropriate barrel area, crosses cytoarchitectural borders of SI and reaches deeply into other unimodal primary cortices such as primary auditory (AI) and primary visual (VI). It was further demonstrated that this spread is supported by a spatially matching underlying diffuse network of border-crossing, long-range projections that could also reach deeply into AI and VI. Here we seek to determine whether such a network of border-crossing, long-range projections is unique to barrel cortex or characterizes also other primary, unimodal sensory cortices and therefore could directly connect them. Using anterograde (BDA) and retrograde (CTb) tract-tracing techniques, we demonstrate that such diffuse horizontal networks directly and mutually connect VI, AI and SI. These findings suggest that diffuse, border-crossing axonal projections connecting directly primary cortices are an important organizational motif common to all major primary sensory cortices in the rat. Potential implications of these findings for topics including cortical structure-function relationships, multisensory integration, functional imaging, and cortical parcellation are discussed.

Interprofessional online learning for primary healthcare: findings from a scoping review.
Reeves, Scott; Fletcher, Simon; McLoughlin, Clodagh; Yim, Alastair; Patel, Kunal D
2017-08-04
This article presents the findings from a scoping review which explored the nature of interprofessional online learning in primary healthcare. The review was informed by the following questions: What is the nature of evidence on online postgraduate education for primary healthcare interprofessional teams? What learning approaches and study methods are used in this context? What is the range of reported outcomes for primary healthcare learners, their organisations and the care they deliver to patients/clients? The review explored the global literature on interprofessional online learning in primary healthcare settings. The review found that the 23 included studies employed a range of different e-learning methods with contrasting course durations, use of theory, participant mix, approaches to accreditation and assessment of learning. Most of the included studies reported outcomes associated with learner reactions and positive changes in participant attitudes/perceptions and improvement in knowledge/skills as a result of engagement in an e-learning course. In contrast, fewer studies reported changes in participant behaviours, changes in organisational practice and improvements to patients/clients. A number of educational, methodological and outcome implications are be offered. E-learning can enhance an education experience, support development, ease time constraints, overcome geographic limitations and can offer greater flexibility. However, it can also contribute to the isolation of learners and its benefits can be negated by technical problems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Persistent hyperplastic primary vitreous is a spectrum of congenital ocular abnormalities characterized by leukocoria, microphthalmia, cataracts, extensive intravitreal hemorrhage, persistence of the hyaloid artery, glaucoma, and retinal detachment. It might be isolated or associated with congenital syndromes such as trisomy 13, Walker-Warburg syndrome, and Norrie disease. We present 2 cases of persistent hyperplastic primary vitreous diagnosed by prenatal sonography in the early third trimester. Bilateral hyperechoic lenses and retinal nonattachment were detected in the sonographic examination of the first case, whereas irregular echogenic bands between the lenses and posterior walls of the eyes were prominent in the second case. In both of the cases, ocular findings were accompanied by intracranial findings, including severe hydrocephalus, an abnormal gyral pattern, and cerebellar hypoplasia, suggesting the diagnosis of Walker-Warburg syndrome. We also present a review of the literature regarding the prenatal diagnosis of this malformation.

Every cancer survivor and his/her primary care provider should receive an individualized survivorship care plan (SCP) following curative treatment. Little is known regarding point-of-care utilization at primary care visits. We assessed SCP utilization in the clinical context of primary care visits. Primary care physicians and advanced practice providers (APPs) who had seen survivors following provision of an SCP were identified. Eligible primary care physicians and APPs were sent an online survey, evaluating SCP utilization and influence on decision-making at the point-of-care, accompanied by copies of the survivor's SCP and the clinic note. Eighty-eight primary care physicians and APPs were surveyed November 2016, with 40 (45%) responding. Most respondents (60%) reported discussing cancer or related issues during the visit. Information needed included treatment (66%) and follow-up visits, and the cancer team was responsible for (58%) vs primary care (58%). Respondents acquired this information by asking the patient (79%), checking oncology notes (75%), the SCP (17%), or online resources (8%). Barriers to SCP use included being unaware of the SCP (73%), difficulty locating it (30%), and finding needed information faster via another mechanism (15%). Despite largely not using the SCP for the visit (90%), most respondents (61%) believed one would be quite or very helpful for future visits. Most primary care visits included discussion of cancer or cancer-related issues. SCPs may provide the information necessary to deliver optimal survivor care but efforts are needed to reduce barriers and design SCPs for primary care use.

AimWe sought to examine strength of primary care service delivery as measured by selected process indicators by general practitioners from 31 European countries plus Australia, Canada, and New Zealand. We explored the relation between strength of service delivery and healthcare expenditures. The strength of a country's primary care is determined by the degree of development of a combination of core primary care dimensions in the context of its healthcare system. This study analyses the strength of service delivery in primary care as measured through process indicators in 31 European countries plus Australia, New Zealand, and Canada. A comparative cross-sectional study design was applied using the QUALICOPC GP database. Data on the strength of primary healthcare were collected using a standardized GP questionnaire, which included 60 questions divided into 10 dimensions related to process, structure, and outcomes. A total of 6734 general practitioners participated. Data on healthcare expenditure were obtained from World Bank statistics. We conducted a correlation analysis to analyse the relationship between strength and healthcare expenditures.FindingsOur findings show that the strength of service delivery parameters is less than optimal in some countries, and there are substantial variations among countries. Continuity and comprehensiveness of care are significantly positively related to national healthcare expenditures; however, coordination of care is not.

What is knowledge and when should it be implemented?
O'Grady, Laura
2012-10-01
A primary purpose of research is to generate new knowledge. Scientific advances have progressively identified optimal ways to achieve this purpose. Included in this evolution are the notions of evidence-based medicine, decision aids, shared decision making, measurement and evaluation as well as implementation. The importance of including qualitative and quantitative methods in our research is now understood. We have debated the meaning of evidence and how to implement it. However, we have yet to consider how to include in our study findings other types of information such as tacit and experiential knowledge. This key consideration needs to take place before we translate new findings or 'knowledge' into clinical practice. This article critiques assumptions regarding the nature of knowledge and suggests a framework for implementing research findings into practice. © 2012 Blackwell Publishing Ltd.

AIM To explore primary care physicians’ perspectives on possible barriers to the use of insulin. METHODS This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eight electronic databases were searched (between January 1, 1994 and August 31, 2014) for relevant studies. A search for grey literature and a review of the references in the retrieved studies were also conducted. Studies that focused on healthcare providers’ perspectives on possible barriers to insulin initiation with type 2 diabetic patients were included, as well as articles suggesting solutions for these barriers. Review articles and studies that only considered patients’ perspectives were excluded. RESULTS A total of 19 studies met the inclusion criteria and were therefore included in this study: 10 of these studies used qualitative methods, 8 used quantitative methods and 1 used mixed methods. Studies included a range of different health care settings. The findings are reported under four broad categories: The perceptions of primary care physicians about the barriers to initiate insulin therapy for type 2 diabetes patients, how primary care physicians assess patients prior to initiating insulin, professional roles and possible solutions to overcome these barriers. The barriers described were many and covered doctor, patient, system and technological aspects. Interventions that focused on doctor training and support, or IT-based decision support were few, and did not result in significant improvement. CONCLUSION Primary care physicians’ known delay in insulin initiation is multifactorial. Published reports of attempts to find solutions for these barriers were limited in number. PMID:28138362

In the UK, more patients go to primary care than other parts of the health service. Therefore it is important for research into primary care to include the insights and views of people who receive these services. To explore the extent, quality and impact of patient and public involvement (PPI) in primary care research, we examined documents of 200 projects and surveyed 191 researchers.We found that about half of studies included PPI to develop research ideas and during the study itself. Common activities included designing study materials, advising on methods, and managing the research. Some studies did not undertake the PPI activities initially planned and funded for. PPI varied by study design, health condition and study population. We found pockets of good practice: having a PPI budget, supporting PPI contributors, and PPI informing recruitment issues. However, good practice was lacking in other areas. Few projects offered PPI contributors training, used PPI to develop information for participants about study progress and included PPI to advise on publishing findings.Researchers reported beneficial impacts of PPI. Most impact was reported when the approach to PPI included more indicators of good practice. The main cost of PPI for researchers was their time. Many reported difficulties providing information about PPI.In partnership with PPI contributors, we have used these findings to develop:a new Cost and Consequences Framework for PPI highlighting financial and non-financial costs, benefits and harms of PPIFifteen co-produced recommendations to improve the practice and delivery of PPI. Background: To improve the lives of patients in primary care requires the involvement of service users in primary care research. We aimed to explore the extent, quality and impact of patient and public involvement (PPI) in primary care research. Methods: We extracted information about PPI from grant applications, reports and an electronic survey of researchers of studies funded by the NIHR School for Primary Care Research (SPCR). We applied recognised quality indicators to assess the quality of PPI and assessed its impact on research. Results: We examined 200 grant applications and reports of 181 projects. PPI was evident in the development of 47 (24%) grant applications. 113 (57%) grant applications included plans for PPI during the study, mostly in study design, oversight, and dissemination. PPI during projects was reported for 83 (46%) projects, including designing study materials and managing the research. We identified inconsistencies between planned and reported PPI. PPI varied by study design, health condition and study population.Of 46 (24%) of 191 questionnaires completed, 15 reported PPI activity. Several projects showed best practice according to guidelines, in terms of having a PPI budget, supporting PPI contributors, and PPI informing recruitment issues. However few projects offered PPI contributors training, used PPI to develop information for participants about study progress, and had PPI in advising on dissemination.Beneficial impacts of PPI in designing studies and writing participant information was frequently reported. Less impact was reported on developing funding applications, managing or carrying out the research. The main cost of PPI for researchers was their time. Many researchers found it difficult to provide information about PPI activities.Our findings informed:a new Cost and Consequences Framework for PPI in primary care research highlighting financial and non-financial costs, plus the benefits and harms of PPIFifteen co-produced recommendations to improve PPI in research and within the SPCR. Conclusions: The extent, quality and impact of PPI in primary care research is inconsistent across research design and topics. Pockets of good practice were identified making a positive impact on research. The new Cost and Consequences Framework may help others assess the impact of PPI.

Primary care models for treating opioid use disorders: What actually works? A systematic review
Klasa, Katarzyna; Bush, Christopher; Heisler, Michele; Chopra, Vineet; Bohnert, Amy
2017-01-01
Background Primary care-based models for Medication-Assisted Treatment (MAT) have been shown to reduce mortality for Opioid Use Disorder (OUD) and have equivalent efficacy to MAT in specialty substance treatment facilities. Objective The objective of this study is to systematically analyze current evidence-based, primary care OUD MAT interventions and identify program structures and processes associated with improved patient outcomes in order to guide future policy and implementation in primary care settings. Data sources PubMed, EMBASE, CINAHL, and PsychInfo. Methods We included randomized controlled or quasi experimental trials and observational studies evaluating OUD treatment in primary care settings treating adult patient populations and assessed structural domains using an established systems engineering framework. Results We included 35 interventions (10 RCTs and 25 quasi-experimental interventions) that all tested MAT, buprenorphine or methadone, in primary care settings across 8 countries. Most included interventions used joint multi-disciplinary (specialty addiction services combined with primary care) and coordinated care by physician and non-physician provider delivery models to provide MAT. Despite large variability in reported patient outcomes, processes, and tasks/tools used, similar key design factors arose among successful programs including integrated clinical teams with support staff who were often advanced practice clinicians (nurses and pharmacists) as clinical care managers, incorporating patient “agreements,” and using home inductions to make treatment more convenient for patients and providers. Conclusions The findings suggest that multidisciplinary and coordinated care delivery models are an effective strategy to implement OUD treatment and increase MAT access in primary care, but research directly comparing specific structures and processes of care models is still needed.

To assess the value of positive immunoglobulin (Ig) M serum antibody (Ab) findings in uveitis patients. We reviewed medical records of patients who had a positive serological test for Toxoplasma gondii-specific IgM Ab. Their clinical data, including history, demographic characteristics, laboratory findings, clinical findings, treatment outcomes, and recurrences, were reviewed retrospectively. Of 2919 uveitis patients who underwent a serological test for suspected ocular toxoplasmosis (OT), 18 presented with positive Ig M results. All 18 patients (100.0% specificity) were clinically diagnosed with OT. None had any retinochoroidal scar at the initial visit, indicating the OT was a recent and primary infection. However, 15 patients (83.3%) had no history suspected to account for the Toxoplasma transmission. The T. gondii IgM serum Ab is a specific biomarker for diagnosis of primary OT. Epidemiological studies are warranted to investigate the non-classic transmission routes of T. gondii in OT.

Facial recognition in primary focal dystonia.
Rinnerthaler, Martina; Benecke, Cord; Bartha, Lisa; Entner, Tanja; Poewe, Werner; Mueller, Joerg
2006-01-01
The basal ganglia seem to be involved in emotional processing. Primary dystonia is a movement disorder considered to result from basal ganglia dysfunction, and the aim of the present study was to investigate emotion recognition in patients with primary focal dystonia. Thirty-two patients with primary cranial (n=12) and cervical (n=20) dystonia were compared to 32 healthy controls matched for age, sex, and educational level on the facially expressed emotion labeling (FEEL) test, a computer-based tool measuring a person's ability to recognize facially expressed emotions. Patients with cognitive impairment or depression were excluded. None of the patients received medication with a possible cognitive side effect profile and only those with mild to moderate dystonia were included. Patients with primary dystonia showed isolated deficits in the recognition of disgust (P=0.007), while no differences between patients and controls were found with regard to the other emotions (fear, happiness, surprise, sadness, and anger). The findings of the present study add further evidence to the conception that dystonia is not only a motor but a complex basal ganglia disorder including selective emotion recognition disturbances.

Shoulder arthroplasty is being performed in the United States with increasing frequency. We describe the medium-term findings from a large integrated healthcare system shoulder arthroplasty registry. Shoulder arthroplasty cases registered between January 2005 and June 2013 were included for analysis. The registry included patient characteristics, surgical information, implant data, attrition, and patient outcomes such as surgical site infections, venous thromboembolism, and revision procedures. During the study period, 6,336 primary cases were registered. Median follow-up time for all primaries was 3.3 years; 461 cases were lost to follow-up by ending of health plan membership. Primary cases were predominantly female (56%) and white (81%), with an average age of 70 years. The most common reason for surgery was osteoarthritis in 60% of cases, followed by acute fracture (17%) and rotator cuff tear arthropathy (15%). In elective shoulder arthroplasty procedures, 200 all-cause revisions (4%) were reported, with glenoid wear being the most common reason. Most arthroplasties were elective procedures: over half performed for osteoarthritis. Glenoid wear was the most common reason for revision of primary shoulder arthroplasty in elective cases.

Key elements of high-quality practice organisation in primary health care: a systematic review.
Crossland, Lisa; Janamian, Tina; Jackson, Claire L
2014-08-04
To identify elements that are integral to high-quality practice and determine considerations relating to high-quality practice organisation in primary care. A narrative systematic review of published and grey literature. Electronic databases (PubMed, CINAHL, the Cochrane Library, Embase, Emerald Insight, PsycInfo, the Primary Health Care Research and Information Service website, Google Scholar) were searched in November 2013 and used to identify articles published in English from 2002 to 2013. Reference lists of included articles were searched for relevant unpublished articles and reports. Data were configured at the study level to allow for the inclusion of findings from a broad range of study types. Ten elements were most often included in the existing organisational assessment tools. A further three elements were identified from an inductive thematic analysis of descriptive articles, and were noted as important considerations in effective quality improvement in primary care settings. Although there are some validated tools available to primary care that identify and build quality, most are single-strategy approaches developed outside health care settings. There are currently no validated organisational improvement tools, designed specifically for primary health care, which combine all elements of practice improvement and whose use does not require extensive external facilitation.

Recognizing Binge-Eating Disorder in the Clinical Setting: A Review of the Literature.
Kornstein, Susan G; Kunovac, Jelena L; Herman, Barry K; Culpepper, Larry
2016-01-01
Review the clinical skills needed to recognize, diagnose, and manage binge-eating disorder (BED) in a primary care setting. A PubMed search of English-language publications (January 1, 2008-December 11, 2014) was conducted using the term binge-eating disorder . Relevant articles known to the authors were also included. Publications focusing on preclinical topics (eg, characterization of receptors and neurotransmitter systems) without discussing clinical relevance were excluded. A total of 101 publications were included in this review. Although BED is the most prevalent eating disorder, it is underdiagnosed and undertreated. BED can be associated with medical (eg, type 2 diabetes and metabolic syndrome) and psychiatric (eg, depression and anxiety) comorbidities that, if left untreated, can impair quality of life and functionality. Primary care physicians may find diagnosing and treating BED challenging because of insufficient knowledge of its new diagnostic criteria and available treatment options. Furthermore, individuals with BED may be reluctant to seek treatment because of shame, embarrassment, and a lack of awareness of the disorder. Several short assessment tools are available to screen for BED in primary care settings. Pharmacotherapy and psychotherapy should focus on reducing binge-eating behavior, thereby reducing medical and psychiatric complications. Overcoming primary care physician- and patient-related barriers is critical to accurately diagnose and appropriately treat BED. Primary care physicians should take an active role in the initial recognition and assessment of suspected BED based on case-finding indicators (eg, eating habits and being overweight), the initial treatment selection, and the long-term follow-up of patients who meet DSM-5 BED diagnostic criteria.

Antimalarial activity of compounds comprising a primary benzene sulfonamide fragment.
Andrews, Katherine T; Fisher, Gillian M; Sumanadasa, Subathdrage D M; Skinner-Adams, Tina; Moeker, Janina; Lopez, Marie; Poulsen, Sally-Ann
2013-11-15
Despite the urgent need for effective antimalarial drugs with novel modes of action no new chemical class of antimalarial drug has been approved for use since 1996. To address this, we have used a rational approach to investigate compounds comprising the primary benzene sulfonamide fragment as a potential new antimalarial chemotype. We report the in vitro activity against Plasmodium falciparum drug sensitive (3D7) and resistant (Dd2) parasites for a panel of fourteen primary benzene sulfonamide compounds. Our findings provide a platform to support the further evaluation of primary benzene sulfonamides as a new antimalarial chemotype, including the identification of the target of these compounds in the parasite.

Breast cancer metastasis to the pituitary gland.
Magalhães, Julia Fragoso; Bacchin, Renata Prota; Costa, Priscila Scatena; Alves, Gisele Malavazi; Fraige Filho, Fadlo; Stella, Lenira Cristina
2014-11-01
Metastatic tumors to the pituitary gland are an unusual complication typically seen in elderly patients with diffuse malignant disease. Breast and lung are the commonest sites of the primary tumor. Prognosis of patients with breast cancer metastasis is poor and depends on the primary neoplastic extension. We report a 54 year-old woman with breast cancer metastasis to the pituitary stalk first diagnosed because of visual disturbance with no other symptoms. Pituitary gland stalk metastasis is a very uncommon find and this case report includes a literature review.

Anxiety Outcomes after Physical Activity Interventions: Meta-Analysis Findings
Conn, Vicki S.
2011-01-01
Background Although numerous primary studies have documented the mental health benefits of physical activity (PA), no previous quantitative synthesis has examined anxiety outcomes of interventions to increase PA. Objectives This meta-analysis integrates extant research about anxiety outcomes from interventions to increase PA among healthy adults. Method Extensive literature searching located published and unpublished PA intervention studies with anxiety outcomes. Eligible studies reported findings from interventions designed to increase PA delivered to healthy adults without anxiety disorders. Data were coded from primary studies. Random-effects meta-analytic procedures were completed. Exploratory moderator analyses using meta-analysis ANOVA and regression analogues were conducted to determine if report, methods, sample, or intervention characteristics were associated with differences in anxiety outcomes. Results Data were synthesized across 3,289 subjects from 19 eligible reports. The overall mean anxiety effect size (d-index) for two-group comparisons was 0.22 with significant heterogeneity (Q = 32.15). Exploratory moderator analyses found larger anxiety improvement effect sizes among studies that included larger samples, used random allocation of subjects to treatment and control conditions, targeted only PA behavior instead of multiple health behaviors, included supervised exercise (vs. home-based PA), used moderate or high-intensity instead of low-intensity PA, and suggested subjects exercise at a fitness facility (vs. home) following interventions. Discussion These findings document that some interventions can decrease anxiety symptoms among healthy adults. Exploratory moderator analyses suggest possible directions for future primary research to compare interventions in randomized trials to confirm causal relationships. PMID:20410849

Embracing value co-creation in primary care services research: a framework for success.
Janamian, Tina; Crossland, Lisa; Jackson, Claire L
2016-04-18
Value co-creation redresses a key criticism of researcher-driven approaches to research - that researchers may lack insight into the end users' needs and values across the research journey. Value co-creation creates, in a step-wise way, value with, and for, multiple stakeholders through regular, ongoing interactions leading to innovation, increased productivity and co-created outcomes of value to all parties - thus creating a "win more-win more" environment. The Centre of Research Excellence (CRE) in Building Primary Care Quality, Performance and Sustainability has co-created outcomes of value that have included robust and enduring partnerships, research findings that have value to end users (such as the Primary Care Practice Improvement Tool and the best-practice governance framework), an International Implementation Research Network in Primary Care and the International Primary Health Reform Conference. Key lessons learned in applying the strategies of value co-creation have included the recognition that partnership development requires an investment of time and effort to ensure meaningful interactions and enriched end user experiences, that research management systems including governance, leadership and communication also need to be "co-creative", and that openness and understanding is needed to work across different sectors and cultures with flexibility, fairness and transparency being essential to the value co-creation process.

We assessed the associations between FDG uptake in primary papillary thyroid carcinomas (PTCs) and clinicopathological features, including the BRAF V600E mutation, using quantitative and qualitative analyses of preoperative PET/CT data. This was a retrospective review of 106 patients with PTC who underwent PET/CT scans between February 2009 and January 2011 before undergoing total thyroidectomy. Data collected from surgical specimens were compared with FDG uptake in the primary tumour using quantitative and qualitative analyses of preoperative PET/CT data. Clinicopathological data included the primary tumour size, subtype, capsular invasion, extrathyroid extension, multifocality, BRAF V600E mutation status, lymph node metastasis and distant metastasis. The SUVmax of the primary tumour was significantly higher in patients with a primary tumour >1 cm, extrathyroid extension or the BRAF V600E mutation than in patients without these features (P<.001, .049 and <.001). Univariate analyses showed that primary tumour size, extrathyroid extension and BRAF V600E mutation status were associated with the SUVmax of the PTC. Multivariate analysis indicated that primary tumour size and the BRAF V600E mutation were associated with the SUVmax of the PTC. In a visual assessment, the primary tumour size was larger in FDG-avid than in non-FDG-avid PTCs (P<.001). There was no significant difference in the presence of multifocality, thyroid capsular invasion, extrathyroid extension, BRAF V600E mutation, lymph node metastasis or distant metastasis between FDG-avid and non-FDG-avid PTCs. Primary tumour size and the BRAF V600E mutation are significant factors associated with the SUVmax on preoperative PET/CT in patients with PTC. © 2017 John Wiley & Sons Ltd.

Effective recruitment strategies in primary care research: a systematic review.
Ngune, Irene; Jiwa, Moyez; Dadich, Ann; Lotriet, Jaco; Sriram, Deepa
2012-01-01
Patient recruitment in primary care research is often a protracted and frustrating process, affecting project timeframes, budget and the dissemination of research findings. Yet, clear guidance on patient recruitment strategies in primary care research is limited. This paper addresses this issue through a systematic review. Articles were sourced from five academic databases - AustHealth, CINAHL, the Cochrane Methodology Group, EMBASE and PubMed/Medline; grey literature was also sourced from an academic library and the Primary Healthcare Research & Information Service (PHCRIS) website. Two reviewers independently screened the articles using the following criteria: (1) published in English, (2) reported empirical research, (3) focused on interventions designed to increase patient recruitment in primary care settings, and (4) reported patient recruitment in primary care settings. Sixty-six articles met the inclusion criteria. Of these, 23 specifically focused on recruitment strategies and included randomised trials (n = 7), systematic reviews (n = 8) and qualitative studies (n = 8). Of the remaining articles, 30 evaluated recruitment strategies, while 13 addressed the value of recruitment strategies using descriptive statistics and/or qualitative data. Among the 66 articles, primary care chiefly included general practice (n = 30); nursing and allied health services, multiple settings, as well as other community settings (n = 30); and pharmacy (n = 6). Effective recruitment strategies included the involvement of a discipline champion, simple patient eligibility criteria, patient incentives and organisational strategies that reduce practitioner workload. The most effective recruitment in primary care research requires practitioner involvement. The active participation of primary care practitioners in both the design and conduct of research helps to identify strategies that are congruent with the context in which patient care is delivered. This is reported to be the optimal recruitment strategy.

Primary perivascular epithelioid cell tumors of the liver: CT/MRI findings and clinical outcomes.
O'Malley, Martin E; Chawla, Tanya P; Lavelle, Lisa P; Cleary, Sean; Fischer, Sandra
2017-06-01
The purpose of our study was to describe the CT and MRI features of primary PEComas of the liver and to document the associated clinical outcomes. Retrospective study included 20 patients with primary hepatic perivascular epithelioid cell tumors (PEComa) with pathology and clinical outcomes for correlation. Study group included 20 patients: 16 women, 4 men; mean age 53 (range 35-77) years. Initial pathology diagnoses were classic angiomyolipoma (AML) (n = 11), epithelioid AML (n = 7), and PEComa not otherwise specified (n = 2). Mean tumor size was 5.1 (range 1.3-15.0) cm. CT/MRI features included well-defined margins 20/20 (100%), arterial enhancement 18/19 (95%), subcapsular location 17/20 (85%), heterogeneous 16/20 (80%), dysmorphic vessels 14/20 (70%), fat 13/20 (65%), hemorrhage 4/20 (20%), cystic components 4/20 (20%), and calcification 1/20 (5%). At the time of discovery, 18 patients were asymptomatic and their tumors were incidentally detected on imaging, and 2 patients were symptomatic. Ultimately, 18 tumors were benign and 2 developed metastases. On CT/MRI, most primary hepatic PEComas were well-defined, arterial enhancing, subcapsular, heterogeneous masses that often had dysmorphic vessels and contained fat. Most tumors were benign but complications included local symptoms, bleeding, and malignant change.

Primary angiitis of the central nervous system remains challenging. To report an overview and pictorial review of brain magnetic resonance imaging findings in adult primary angiitis of the central nervous system and to determine the distribution of parenchymal, meningeal, and vascular lesions in a large multicentric cohort. Adult patients from the French COVAC cohort (Cohort of Patients With Primary Vasculitis of the Central Nervous System), with biopsy or angiographically proven primary angiitis of the central nervous system and brain magnetic resonance imaging available at the time of diagnosis were included. A systematic imaging review was performed blinded to clinical data. Sixty patients met inclusion criteria. Mean age was 45 years (±12.9). Patients initially presented focal deficit(s) (83%), headaches (53%), cognitive disorder (40%), and seizures (38.3%). The most common magnetic resonance imaging finding observed in 42% of patients was multiterritorial, bilateral, distal acute stroke lesions after small to medium artery distribution, with a predominant carotid circulation distribution. Hemorrhagic infarctions and parenchymal hemorrhages were also frequently found in the cohort (55%). Acute convexity subarachnoid hemorrhage was found in 26% of patients and 42% demonstrated pre-eminent leptomeningeal enhancement, which is found to be significantly more prevalent in biopsy-proven patients (60% versus 28%; P =0.04). Seven patients had tumor-like presentations. Seventy-seven percent of magnetic resonance angiographic studies were abnormal, revealing proximal/distal stenoses in 57% and 61% of patients, respectively. Adult primary angiitis of the central nervous system is a heterogenous disease, with multiterritorial, distal, and bilateral acute stroke being the most common pattern of parenchymal lesions found on magnetic resonance imaging. Our findings suggest a higher than previously thought prevalence of hemorrhagic transformation and other hemorrhagic manifestations. © 2017 American Heart Association, Inc.

How to conduct a qualitative meta-analysis: Tailoring methods to enhance methodological integrity.
Levitt, Heidi M
2018-05-01
Although qualitative research has long been of interest in the field of psychology, meta-analyses of qualitative literatures (sometimes called meta-syntheses) are still quite rare. Like quantitative meta-analyses, these methods function to aggregate findings and identify patterns across primary studies, but their aims, procedures, and methodological considerations may vary. This paper explains the function of qualitative meta-analyses and their methodological development. Recommendations have broad relevance but are framed with an eye toward their use in psychotherapy research. Rather than arguing for the adoption of any single meta-method, this paper advocates for considering how procedures can best be selected and adapted to enhance a meta-study's methodological integrity. Through the paper, recommendations are provided to help researchers identify procedures that can best serve their studies' specific goals. Meta-analysts are encouraged to consider the methodological integrity of their studies in relation to central research processes, including identifying a set of primary research studies, transforming primary findings into initial units of data for a meta-analysis, developing categories or themes, and communicating findings. The paper provides guidance for researchers who desire to tailor meta-analytic methods to meet their particular goals while enhancing the rigor of their research.

Physician-patient communication in the primary care office: a systematic review.
Beck, Rainer S; Daughtridge, Rebecca; Sloane, Philip D
2002-01-01
The physician-patient interview is the key component of all health care, particularly of primary medical care. This review sought to evaluate existing primary-care-based research studies to determine which verbal and nonverbal behaviors on the part of the physician during the medical encounter have been linked in empirical studies with favorable patient outcomes. We reviewed the literature from 1975 to 2000 for studies of office interactions between primary care physicians and patients that evaluated these interactions empirically using neutral observers who coded observed encounters, videotapes, or audiotapes. Each study was reviewed for the quality of the methods and to find statistically significant relations between specific physician behaviors and patient outcomes. In examining nonverbal behaviors, because of a paucity of clinical outcome studies, outcomes were expanded to include associations with patient characteristics or subjective ratings of the interaction by observers. We found 14 studies of verbal communication and 8 studies of nonverbal communication that met inclusion criteria. Verbal behaviors positively associated with health outcomes included empathy, reassurance and support, various patient-centered questioning techniques, encounter length, history taking, explanations, both dominant and passive physician styles, positive reinforcement, humor, psychosocial talk, time in health education and information sharing, friendliness, courtesy, orienting the patient during examination, and summarization and clarification. Nonverbal behaviors positively associated with outcomes included head nodding, forward lean, direct body orientation, uncrossed legs and arms, arm symmetry, and less mutual gaze. Existing research is limited because of lack of consensus of what to measure, conflicting findings, and relative lack of empirical studies (especially of nonverbal behavior). Nonetheless, medical educators should focus on teaching and reinforcing behaviors known to be facilitative, and to continue to understand further how physician behavior can enhance favorable patient outcomes, such as understanding and adherence to medical regimens and overall satisfaction.

Effect of a Diagram on Primary Students' Understanding About Electric Circuits
NASA Astrophysics Data System (ADS)
Preston, Christine Margaret
2017-09-01
This article reports on the effect of using a diagram to develop primary students' conceptual understanding about electric circuits. Diagrammatic representations of electric circuits are used for teaching and assessment despite the absence of research on their pedagogical effectiveness with young learners. Individual interviews were used to closely analyse Years 3 and 5 (8-11-year-old) students' explanations about electric circuits. Data was collected from 20 students in the same school providing pre-, post- and delayed post-test dialogue. Students' thinking about electric circuits and changes in their explanations provide insights into the role of diagrams in understanding science concepts. Findings indicate that diagram interaction positively enhanced understanding, challenged non-scientific views and promoted scientific models of electric circuits. Differences in students' understanding about electric circuits were influenced by prior knowledge, meta-conceptual awareness and diagram conventions including a stylistic feature of the diagram used. A significant finding that students' conceptual models of electric circuits were energy rather than current based has implications for electricity instruction at the primary level.

Using collective argumentation to engage students in a primary mathematics classroom
NASA Astrophysics Data System (ADS)
Brown, Raymond
2017-02-01
This article focuses on using sociocultural theory to support student engagement with mathematics. The sociocultural approach used, collective argumentation (CA), is based on interactive principles necessary for coordinating student engagement in the discourse of the classroom. A goal of the research was to explore the affordances and constraints of using CA to enrich student engagement with mathematics. The design of the research was based on a teaching experiment that sought to capture the influence of social and cultural processes on learning and development. Participants included primary and secondary school teachers and their mathematics classes. This article focuses on the practice of one female primary school teacher. Data sources included interview transcripts, report writings, journal entries and observational records. Data were analysed using a participation framework. Findings suggest that aspects of CA such as students explaining and justifying ideas and presenting ideas to the whole class can be used by teachers to promote student engagement with mathematics.

Use of the internet for health information among primary care patients in rural West Texas.
Zhang, Yan; Jones, Betsy; Spalding, Mary; Young, Rodney; Ragain, Mike
2009-06-01
Little is known about how primary care patients in rural, remote or border areas use the internet for their health information. This study examined the factors related to internet use for medical information among primary care clinic patients in such areas of West Texas. A convenience sample was drawn from nine clinics that serve low-income rural area populations. Surveys were distributed to the patients during a 6-week period in the winter of 2006. The analytical sample included 1890 participants. Logistic regressions were conducted. Of 1890 subjects, 699 (37%) reported having used the internet for medical information. Among those who reported using the internet for health information, respondents' primary usage pattern was to request more health information (29.9%), followed by the purchase of health supplies (13.4%). Most internet users (78.8%) agreed that the online medical/health information had improved their understanding of a specific condition, disease, or treatment. Almost 60% of the internet users thought the information was reliable. The correlates of internet use included health insurance, self-rated health, health confidence, and number of worried days as well as age, education level, ethnicity, and language. Our findings showed a much lower rate of internet use for medical/health information compared with a 2006 nationwide survey. This finding suggests that promoting health/medical information through websites or other on-line resources might not be the most effective way to reach a majority of patients in remote, rural or border areas.

Role of computed tomography angiography in detection and staging of small bowel carcinoid tumors
Bonekamp, David; Raman, Siva P; Horton, Karen M; Fishman, Elliot K
2015-01-01
Small-bowel carcinoid tumors are the most common form (42%) of gastrointestinal carcinoids, which by themselves comprise 70% of neuroendocrine tumors. Although primary small bowel neoplasms are overall rare (3%-6% of all gastrointestinal neoplasms), carcinoids still represent the second most common (20%-30%) primary small-bowel malignancy after small bowel adenocarcinoma. Their imaging evaluation is often challenging. State-of-the-art high-resolution multiphasic computed tomography together with advanced postprocessing methods provides an excellent tool for their depiction. The manifold interactive parameter choices however require knowledge of when to use which technique. Here, we discuss the imaging appearance and evaluation of duodenal, jejunal and ileal carcinoid tumors, including the imaging features of the primary tumor, locoregional mesenteric nodal metastases, and distant metastatic disease. A protocol for optimal lesion detection is presented, including the use of computed tomography enterography, volume acquisition, computed tomography angiography and three-dimensional mapping. Imaging findings are illustrated with a series of challenging cases which illustrate the spectrum of possible disease in the small bowel and mesentery, the range of possible appearances in the bowel itself on multiphase data and extraluminal findings such as the desmoplastic reaction in mesentery and hypervascular liver metastases. Typical imaging pitfalls and pearls are illustrated. PMID:26435774

Long non-coding RNAs may serve as biomarkers in breast cancer combined with primary lung cancer
Mao, Weimin; Chen, Bo; Yang, Shifeng; Ding, Xiaowen; Zou, Dehong; Mo, Wenju; He, Xiangming; Zhang, Xiping
2017-01-01
Long non-coding RNAs (lncRNAs) have been shown to play important regulatory role in certain type of cancers biology, including breast and lung cancers. However, the lncRNA expression in breast cancer combined with primary lung cancer remains unknown. In this study, databases of the Cancer Genome Atlas (TCGA) and the lncRNA profiler of contained candidate 192 lncRNAs were utilized. 11 lncRNAs were differentially expressed in breast cancer, 9 candidate lncRNAs were differentially expressed in lung cancer. In order to find the aberrant expression of lncRNAs in breast cancer combined with primary lung cancer, seven samples of primary breast cancer and lung cancer were studied for the expression of selected lncRNAs. The results showed that SNHG6 and NEAT1 were reversely expressed in breast cancer combined with primary lung cancer compared with primary breast or lung cancer. In addition, a significant correlation of lncRNAs was found in the patients whose age was above 56 in breast cancer. What's more, PVT1 expression was negatively correlated with the pathological stage, and the level of ER, PR, HER2, p53 in breast cancer. Furthermore, lncRNA expression did not have significant relationship with the 5-year survival of patients with breast cancer combined with primary lung cancer. The findings revealed that PVT1, SNHG6, NEAT1 may serve as a prognostic marker for breast cancer combined with primary lung cancer. Therefore, these lncRNAs are potential molecular indicators in the diagnosis and prognosis of cancer in the future. PMID:28938549

This systematic review and meta-regression analysis aimed to calculate a combined prevalence estimate and evaluate the prevalence of different Treponema species in primary and secondary endodontic infections, including symptomatic and asymptomatic cases. The MEDLINE/PubMed, Embase, Scielo, Web of Knowledge, and Scopus databases were searched without starting date restriction up to and including March 2014. Only reports in English were included. The selected literature was reviewed by 2 authors and classified as suitable or not to be included in this review. Lists were compared, and, in case of disagreements, decisions were made after a discussion based on inclusion and exclusion criteria. A pooled prevalence of Treponema species in endodontic infections was estimated. Additionally, a meta-regression analysis was performed. Among the 265 articles identified in the initial search, only 51 were included in the final analysis. The studies were classified into 2 different groups according to the type of endodontic infection and whether it was an exclusively primary/secondary study (n = 36) or a primary/secondary comparison (n = 15). The pooled prevalence of Treponema species was 41.5% (95% confidence interval, 35.9-47.0). In the multivariate model of meta-regression analysis, primary endodontic infections (P < .001), acute apical abscess, symptomatic apical periodontitis (P < .001), and concomitant presence of 2 or more species (P = .028) explained the heterogeneity regarding the prevalence rates of Treponema species. Our findings suggest that Treponema species are important pathogens involved in endodontic infections, particularly in cases of primary and acute infections.

There is a pressing need for greater attention to patient-centered health behavior and psychosocial issues in primary care, and for practical tools, study designs and results of clinical and policy relevance. Our goal is to design a scientifically rigorous and valid pragmatic trial to test whether primary care practices can systematically implement the collection of patient-reported information and provide patients needed advice, goal setting, and counseling in response. This manuscript reports on the iterative design of the My Own Health Report (MOHR) study, a cluster randomized delayed intervention trial. Nine pairs of diverse primary care practices will be randomized to early or delayed intervention four months later. The intervention consists of fielding the MOHR assessment--addresses 10 domains of health behaviors and psychosocial issues--and subsequent provision of needed counseling and support for patients presenting for wellness or chronic care. As a pragmatic participatory trial, stakeholder groups including practice partners and patients have been engaged throughout the study design to account for local resources and characteristics. Participatory tasks include identifying MOHR assessment content, refining the study design, providing input on outcomes measures, and designing the implementation workflow. Study outcomes include the intervention reach (percent of patients offered and completing the MOHR assessment), effectiveness (patients reporting being asked about topics, setting change goals, and receiving assistance in early versus delayed intervention practices), contextual factors influencing outcomes, and intervention costs. The MOHR study shows how a participatory design can be used to promote the consistent collection and use of patient-reported health behavior and psychosocial assessments in a broad range of primary care settings. While pragmatic in nature, the study design will allow valid comparisons to answer the posed research question, and findings will be broadly generalizable to a range of primary care settings. Per the pragmatic explanatory continuum indicator summary (PRECIS) framework, the study design is substantially more pragmatic than other published trials. The methods and findings should be of interest to researchers, practitioners, and policy makers attempting to make healthcare more patient-centered and relevant. Clinicaltrials.gov: NCT01825746.

Paying for Primary Care: The Factors Associated with Physician Self-selection into Payment Models.
Rudoler, David; Deber, Raisa; Barnsley, Janet; Glazier, Richard H; Dass, Adrian Rohit; Laporte, Audrey
2015-09-01
To determine the factors associated with primary care physician self-selection into different payment models, we used a panel of eight waves of administrative data for all primary care physicians who practiced in Ontario between 2003/2004 and 2010/2011. We used a mixed effects logistic regression model to estimate physicians' choice of three alternative payment models: fee for service, enhanced fee for service, and blended capitation. We found that primary care physicians self-selected into payment models based on existing practice characteristics. Physicians with more complex patient populations were less likely to switch into capitation-based payment models where higher levels of effort were not financially rewarded. These findings suggested that investigations aimed at assessing the impact of different primary care reimbursement models on outcomes, including costs and access, should first account for potential selection effects.

Wenjing decoction is a well-accepted traditional Chinese medicine for the treatment of primary dysmenorrhea in East Asia, but its clinical effectiveness and risk have not been adequately assessed. In this paper, we conducted a systematic review and meta-analysis to evaluate the efficacy of Wenjing decoction for the treatment of primary dysmenorrhea. Eight databases were used in our research: the Cochrane Library, the Web of Science, PubMed, EMBASE, the Chinese Biomedical Literature Database (CBM), the Chinese National Knowledge Infrastructure (CNKI), the Chinese Scientific Journal Database, and the Wan-fang Database. The following search terms were used: (Wenjing decoction OR Wenjing formula OR Wenjing tang) AND (primary dysmenorrhea OR dysmenorrhea OR painful menstruation) AND (randomized controlled trial). No language limitation was used. A total of 18 studies, including 1736 patients, were included in the meta-analysis. Wenjing decoction was shown to be significantly better than nonsteroidal anti-inflammatory drugs for the improvement of primary dysmenorrhea according to the clinical effective rate (RR 1.41, 95% CI 1.24-1.61), the visual analogue scale (MD -1.77, 95% CI -2.69 to -0.84), and the pain scale for dysmenorrhea (MD -1.81, 95% CI -2.41 to -1.22). The results supported the clinical use of Wenjing decoction for the treatment of primary dysmenorrhea. However, the quality of the evidence for this finding was low due to a high risk of bias in the included studies. Therefore, well-designed randomized controlled trials are still needed to further evaluate the efficacy of Wenjing decoction for the treatment of primary dysmenorrhea.

Non-surgical treatment of dentin caries in preschool children--systematic review.
Duangthip, Duangporn; Jiang, Ming; Chu, Chun Hung; Lo, Edward C M
2015-04-03
Untreated dentin caries in primary teeth is commonly found in preschool children worldwide. Recently, the use of simple non-surgical approaches to manage the situation has been advocated. The aim of the study was to systematically review and evaluate the literature on effectiveness of non-surgical methods in arresting or slowing down the progression of active dentin caries in primary teeth in preschool children. A systematic search of the main electronic databases (Pubmed, Cochrane Collaboration, EMBASE) was conducted to identify peer reviewed papers published in English in the years 1947-2014. Keywords and MeSH terms used in the search were "dental caries", "primary dentition" and various non-surgical treatments (fluoride, sealant, resin infiltration, xylitol, chlorhexidine, CPP-ACP, ozone, etc.). The inclusion criteria were clinical studies conducted in children under 6 years old, and reported findings on caries arrest or caries progression in primary teeth. Retrieved papers were read by two reviewers independently to assess suitability for inclusion, and the final decision was made by consensus. Quality of the included studies was assessed and data were extracted for analysis. The search identified 323 papers for screening. Among these, 290 papers did not satisfy the study inclusion criteria. Consequently, 33 full papers were retrieved and reviewed. Finally, 4 studies were included. Three studies reported that topical applications of silver diammine fluoride (SDF) solution could arrest dentin caries in preschool children. One study supported that having a daily toothbrushing exercise in kindergarten using toothpaste with 1000 ppm fluoride could stabilize the caries situation in young children. There is limited evidence to support the effectiveness of SDF applications or daily toothbrushing with fluoride toothpaste in arresting or slowing down the progression of active dentin caries in primary teeth in preschool children. More well-designed randomized controlled trials are required to confirm these findings.

Recognizing Binge-Eating Disorder in the Clinical Setting: A Review of the Literature
Kornstein, Susan G.; Kunovac, Jelena L.; Herman, Barry K.; Culpepper, Larry
2016-01-01
Objective: Review the clinical skills needed to recognize, diagnose, and manage binge-eating disorder (BED) in a primary care setting. Data Sources: A PubMed search of English-language publications (January 1, 2008–December 11, 2014) was conducted using the term binge-eating disorder. Relevant articles known to the authors were also included. Study Selection/Data Extraction: Publications focusing on preclinical topics (eg, characterization of receptors and neurotransmitter systems) without discussing clinical relevance were excluded. A total of 101 publications were included in this review. Results: Although BED is the most prevalent eating disorder, it is underdiagnosed and undertreated. BED can be associated with medical (eg, type 2 diabetes and metabolic syndrome) and psychiatric (eg, depression and anxiety) comorbidities that, if left untreated, can impair quality of life and functionality. Primary care physicians may find diagnosing and treating BED challenging because of insufficient knowledge of its new diagnostic criteria and available treatment options. Furthermore, individuals with BED may be reluctant to seek treatment because of shame, embarrassment, and a lack of awareness of the disorder. Several short assessment tools are available to screen for BED in primary care settings. Pharmacotherapy and psychotherapy should focus on reducing binge-eating behavior, thereby reducing medical and psychiatric complications. Conclusions: Overcoming primary care physician– and patient-related barriers is critical to accurately diagnose and appropriately treat BED. Primary care physicians should take an active role in the initial recognition and assessment of suspected BED based on case-finding indicators (eg, eating habits and being overweight), the initial treatment selection, and the long-term follow-up of patients who meet DSM-5 BED diagnostic criteria.

Barriers and facilitators in the integration of oral health into primary care: a scoping review
Harnagea, Hermina; Couturier, Yves; Shrivastava, Richa; Girard, Felix; Lamothe, Lise; Bedos, Christophe Pierre
2017-01-01
Objective This scoping study has been conducted to map the literature and provide a descriptive synthesis on the barriers and facilitators of the integration of oral health into primary care. Methods Grounded in the Rainbow conceptual model and using the Levac et al six-stage framework, we performed a systematic search of electronic databases, organisational websites and grey literature from 1978 to April 2016. All publications with a focus on the integration of oral health into primary care were included except commentaries and editorials. Thematic analyses were performed to synthesise the results. Results From a total of 1619 citations, 58 publications were included in the review. Barrier-related themes included: lack of political leadership and healthcare policies; implementation challenges; discipline-oriented education; lack of continuity of care and services and patients’ oral healthcare needs. The facilitators of integration were supportive policies and resources allocation, interdisciplinary education, collaborative practices between dental and other healthcare professionals, presence of local strategic leaders and geographical proximity. Discussion and public health implications This work has advanced the knowledge on the barriers and facilitators at each integration domain and level, which may be helpful if the healthcare organisations decide to integrate oral health and dental services into primary care. The scoping review findings could be useful for both dental and medical workforce and allied primary healthcare providers. They could also guide the development of healthcare policies that support collaborative practices and patient-centred care in the field of primary care. PMID:28951405

Why practice yoga? Practitioners' motivations for adopting and maintaining yoga practice.
Park, Crystal L; Riley, Kristen E; Bedesin, Elena; Stewart, V Michelle
2016-06-01
We examined motives for adopting and maintaining yoga practice in a national survey of yoga practitioners (360 yoga students, 156 yoga teachers). Both students and teachers adopted yoga practice primarily for exercise and stress relief, but reported many other reasons, including flexibility, getting into shape, and depression/anxiety relief. Over 62 percent of students and 85 percent of teachers reported having changed their primary reason for practicing or discovering other reasons; for both, the top changed primary reason was spirituality. Findings suggest that most initiate yoga practice for exercise and stress relief, but for many, spirituality becomes their primary reason for maintaining practice. © The Author(s) 2014.

The purpose of this study was to examine the social validity of the Social Skills Improvement System-Classwide Intervention Program (SSIS-CIP) for teachers in the primary grades. Participants included 45 first and second grade teachers who completed a 16-item social validity questionnaire during each year of the SSIS-CIP efficacy trial. Findings indicated that teachers generally perceived the SSIS-CIP as a socially valid and feasible intervention for primary grades; however, teachers' ratings regarding ease of implementation and relevance and sequence demonstrated differences across grade levels in the second year of implementation.

Background Research on gay and other men who have sex with men's (G/MSM) preferences for sexual healthcare services focuses largely on HIV testing and to some extent on sexually transmitted infections (STI). This research illustrates the frequency and location of where G/MSM interface with the healthcare system, but it does not speak to why men seek care in those locations. As HIV and STI prevention strategies evolve, evidence about G/MSM's motivations and decision-making can inform future plans to optimize models of HIV/STI prevention and primary care. Methods We conducted a phenomenological study of gay men's sexual health seeking experiences, which included 32 in-depth interviews with gay and bisexual men. Interviews were transcribed verbatim and entered into Atlas.ti. We conducted a Framework Analysis. Findings We identified a continuum of sexual healthcare seeking practices and their associated drivers. Men differed in their preferences for separating sexual healthcare from other forms of healthcare (“fragmentation”) versus combining all care into one location (“consolidation”). Fragmentation drivers included: fear of being monitored by insurance companies, a desire to seek non-judgmental providers with expertise in sexual health, a desire for rapid HIV testing, perceiving sexual health services as more convenient than primary care services, and a lack of healthcare coverage. Consolidation drivers included: a comfortable and trusting relationship with a provider, a desire for one provider to oversee overall health and those with access to public or private health insurance. Conclusions Men in this study were likely to separate sexual healthcare from primary care. Based on this finding, we recommend placing new combination HIV/STI prevention interventions within sexual health clinics. Furthermore, given the evolution of the financing and delivery of healthcare services and in HIV prevention, policymakers and clinicians should consider including more primary care services within sexual healthcare settings.

This article presents results from a mixed-method evaluation of a structured cooking and gardening program in Australian primary schools, focusing on program impacts on the social and learning environment of the school. In particular, we address the Stephanie Alexander Kitchen Garden Program objective of providing a pleasurable experience that has a positive impact on student engagement, social connections, and confidence within and beyond the school gates. Primary evidence for the research question came from qualitative data collected from students, parents, teachers, volunteers, school principals, and specialist staff through interviews, focus groups, and participant observations. This was supported by analyses of quantitative data on child quality of life, cooperative behaviors, teacher perceptions of the school environment, and school-level educational outcome and absenteeism data. Results showed that some of the program attributes valued most highly by study participants included increased student engagement and confidence, opportunities for experiential and integrated learning, teamwork, building social skills, and connections and links between schools and their communities. In this analysis, quantitative findings failed to support findings from the primary analysis. Limitations as well as benefits of a mixed-methods approach to evaluation of complex community interventions are discussed.

How, what, and why of sleep apnea. Perspectives for primary care physicians.
Chung, Sharon A; Jairam, Shani; Hussain, Mohamed R G; Shapiro, Colin M
2002-06-01
To review the need for primary care physicians to screen for patients with obstructive sleep apnea (OSA). Literature was reviewed via MEDLINE from 1993 to 2000, inclusive, using the search term "sleep apnea" combined with "epidemiology," "outcome," and "diagnosis and treatment." Citations in this review favour more recent, well controlled and randomized studies, but findings of pilot studies are included where other research is unavailable. Obstructive sleep apnea is a disorder with serious medical, socioeconomic, and psychological morbidity, yet most patients with OSA remain undetected. Primary care physicians have a vital role in screening for these patients because diagnosis can be made only through overnight (polysomnographic) studies at sleep clinics. Physicians should consider symptoms of excessive or loud snoring, complaints of daytime sleepiness or fatigue, complaints of unrefreshing sleep, and an excess of weight or body fat distribution in the neck or upper chest area as possible indications of untreated OSA. Current research findings indicate that treating OSA patients substantially lowers morbidity and mortality rates and reduces health care costs. Primary care physicians need more information about screening for patients with OSA to ensure proper diagnosis and treatment of those with the condition.

To 1) describe patterns of specialty choice; 2) investigate relationships between career selection and selected demographic indicators; and 3) identify salary perception, factors that influence career choice in primary care, and factors that influence desired location of future medical practice. The study used a mixed-methods approach that included a cross-sectional questionnaire survey applied to 234 last-year medical students in Honduras (September 2014), and semi-structured interviews with eight key informants (October 2014). Statistical analysis included chi-square and factor analysis. An alpha level of 0.05 was used to determine significance. In the qualitative analysis, several codes were associated with each other, and five major themes emerged. Primary care careers were the preferred choice for 8.1% of students, who preferred urban settings for future practice location. The perceived salary of specialties other than primary care was significantly higher than those of general practitioners, family practitioners, and pediatricians (P < 0.001). Participants considered "making a difference," income, teaching, prestige, and challenging work the most important factors influencing career choice. Practice in ambulatory settings was significantly associated with a preference for primary care specialties (P = < 0.05). Logistic regression analysis found that factors related to patient-based care were statistically significant for selecting primary care (P = 0.006). The qualitative analysis further endorsed the survey findings, identifying additional factors that influence career choice (future work option; availability of residency positions; and social factors, including violence). Rationales behind preference of a specialty appeared to be based on a combination of ambition and prestige, and on personal and altruistic considerations. Most factors that influence primary care career choice are similar to those found in the literature. There are several factors distinctive to medical students in Honduras-most of them barriers to primary care career choice.

To evaluate the efficacy of bilateral selective neck dissection of levels II-IV in elective and therapeutic management of the neck as a part of primary surgical treatment of patients with supraglottic laryngeal cancer and clinically negative cervical findings (N0). Institutional, observational, case-control study with historic control of patients who underwent primary supraglottic tumour surgery, and a prospective cohort of patient, who underwent, besides the operation of primary tumour, bilateral selective neck dissection (level II-IV). University, tertiary level hospital, national referral centre. The study included 193 patients with supraglottic cancer and without palpable or ultrasound positive cervical findings who were surgically treated from 1988 to 2005. Besides the operation of primary tumour, all patients in the study group underwent bilateral selective neck dissection (level II-IV). Patients in the control group (N = 51) underwent primary tumour operation only and were followed up regularly. In cases with postoperative regional recurrences, the radical neck dissection was performed. All patients with histopathological confirmation of occult metastases were administered radiotherapy treatment (60 Gy) in the postoperative period. Five-year overall survival rate. Occult cervical metastases were found in 18% of patients. They were present in level II in 77.5%, in level III in 20% of cases and in one patient in level IV (2.5%); the extracapsular spread was observed in 20% of cases. Postoperative regional metastases were found in 4.15% of cases in the study group, and in 11.8% in the control group, which proved to be significantly higher. The five-year overall survival rate showed no significant difference between the study group and the control group. The incidence of postoperative regional recurrences could be reduced by performing bilateral selective neck dissection simultaneously with primary tumour operation, but with no influence on the survival rate. © 2015 John Wiley & Sons Ltd.

Primary health care reform, dilemmatic space and risk of burnout among health workers.
Freeman, Toby; Baum, Fran; Labonté, Ronald; Javanparast, Sara; Lawless, Angela
2018-05-01
Health system changes may increase primary health care workers' dilemmatic space, created when reforms contravene professional values. Dilemmatic space may be a risk factor for burnout. This study partnered with six Australian primary health care services (in South Australia: four state government-managed services including one Aboriginal health team and one non-government organisation and in Northern Territory: one Aboriginal community-controlled service) during a period of change and examined workers' dilemmatic space and incidence of burnout. Dilemmatic space and burnout were assessed in a survey of 130 staff across the six services (58% response rate). Additionally, 63 interviews were conducted with practitioners, managers, regional executives and health department staff. Dilemmatic space occurred across all services and was associated with higher rates of self-reported burnout. Three conditions associated with dilemmatic space were (1) conditions inherent in comprehensive primary health care, (2) stemming from service provision for Aboriginal and Torres Strait Islander peoples and (3) changes wrought by reorientation to selective primary health care in South Australia. Responses to dilemmatic space included ignoring directives or doing work 'under the radar', undertaking alternative work congruent with primary health care values outside of hours, or leaving the organisation. The findings show that comprehensive primary health care was contested and political. Future health reform processes would benefit from considering alignment of changes with staff values to reduce negative effects of the reform and safeguard worker wellbeing.

Registered nurses are under-represented in the primary health care setting both internationally and in Australia, and this shortage is predicted to worsen. To address the increasingly complex healthcare needs of an ageing population, it is vital to develop and sustain a primary health care nursing workforce, yet attracting nurses is challenging. In Australia, registered nurses graduating from university typically commence their careers in hospital-based transition to professional practice programs. Similar programs in primary health care settings may be a valuable strategy for developing the primary health care nursing workforce, yet little is known about nursing students desire to work in this setting, factors that influence this, or their expectations of primary health care-focused transition to professional practice programs. This study sought to identify factors associated with final year nursing students' desire to work in primary health care setting including demographic factors, expectations of future employment conditions, and job content. It also explored expectations of graduate transition programs based in primary health care. A cross-sectional survey design comprising a quantitative online survey. 14 Australian universities from all states/territories, both rural and urban. 530 final-year nursing students. Binary logistic regression identifying factors contributing to desire to work in primary health care. The desire of nursing students to work in primary health care is associated with older age, greater perceived value of employment conditions including flexibility, and less perceived importance of workplace support. Collaborative efforts from primary health care nurses, health professionals, academics and policy makers are needed to attract new graduate nurses to primary health care. Crown Copyright © 2017.

The Patient Health Questionnaire (PHQ) is the most commonly used measure to screen for depression in primary care but there is still lack of clarity about its accuracy and optimal scoring method. To determine via meta-analysis the diagnostic accuracy of the PHQ-9-linear, PHQ-9-algorithm and PHQ-2 questions to detect major depressive disorder (MDD) among adults. We systematically searched major electronic databases from inception until June 2015. Articles were included that reported the accuracy of PHQ-9 or PHQ-2 questions for diagnosing MDD in primary care defined according to standard classification systems. We carried out a meta-analysis, meta-regression, moderator and sensitivity analysis. Overall, 26 publications reporting on 40 individual studies were included representing 26 902 people (median 502, s.d.=693.7) including 14 760 unique adults of whom 14.3% had MDD. The methodological quality of the included articles was acceptable. The meta-analytic area under the receiver operating characteristic curve of the PHQ-9-linear and the PHQ-2 was significantly higher than the PHQ-9-algorithm, a difference that was maintained in head-to-head meta-analysis of studies. Our best estimates of sensitivity and specificity were 81.3% (95% CI 71.6-89.3) and 85.3% (95% CI 81.0-89.1), 56.8% (95% CI 41.2-71.8) and 93.3% (95% CI 87.5-97.3) and 89.3% (95% CI 81.5-95.1) and 75.9% (95% CI 70.1-81.3) for the PHQ-9-linear, PHQ-9-algorithm and PHQ-2 respectively. For case finding (ruling in a diagnosis), none of the methods were suitable but for screening (ruling out non-cases), all methods were encouraging with good clinical utility, although the cut-off threshold must be carefully chosen. The PHQ can be used as an initial first step assessment in primary care and the PHQ-2 is adequate for this purpose with good acceptability. However, neither the PHQ-2 nor the PHQ-9 can be used to confirm a clinical diagnosis (case finding). None. © The Royal College of Psychiatrists 2016.

Patients with potentially ischemic chest pain are commonly admitted to the hospital or observed after a negative evaluation in the emergency department (ED) owing to concern about adverse events. Previous studies have looked at 30-day mortality, but no current large studies have examined the most important information regarding ED disposition: the short-term risk for a clinically relevant adverse cardiac event (including inpatient ST-segment elevation myocardial infarction, life-threatening arrhythmia, cardiac or respiratory arrest, or death). To determine the incidence of clinically relevant adverse cardiac events in patients hospitalized for chest pain with 2 troponin-negative findings, nonconcerning initial ED vital signs, and nonischemic, interpretable electrocardiographic findings. We conducted a blinded data review of 45,416 encounters obtained from a prospectively collected database enrolling adult patients admitted or observed with the following inclusion criteria: (1) primary presenting symptom of chest pain, chest tightness, chest burning, or chest pressure and (2) negative findings for serial biomarkers. Data were collected and analyzed from July 1, 2008, through June 30, 2013, from the EDs of 3 community teaching institutions with an aggregate census of more than 1 million visits. We analyzed data extracted by hypothesis-blinded abstractors. The primary outcome was a composite of life-threatening arrhythmia, inpatient ST-segment elevation myocardial infarction, cardiac or respiratory arrest, or death during hospitalization. Of the 45,416 encounters, 11,230 met criteria for inclusion. Mean patient age was 58.0 years. Of the 11 230 encounters, 44.83% of patients arrived by ambulance and 55.00% of patients were women. Relevant history included hypertension in 46.00%, diabetes mellitus in 19.72%, and myocardial infarction in 13.16%. The primary end point occurred in 20 of the 11 230 patients (0.18% [95% CI, 0.11%-0.27%]). After excluding patients with abnormal vital signs, electrocardiographic ischemia, left bundle branch block, or a pacemaker rhythm, we identified a primary end point event in 4 of 7266 patients (0.06% [95% CI, 0.02%-0.14%]). Of these events, 2 were noncardiac and 2 were possibly iatrogenic. In adult patients with chest pain admitted with 2 negative findings for serial biomarkers, nonconcerning vital signs, and nonischemic electrocardiographic findings, short-term clinically relevant adverse cardiac events were rare and commonly iatrogenic, suggesting that routine inpatient admission may not be a beneficial strategy for this group.

This article presents qualitative research findings of Section 8 landlord perceptions regarding healthy housing practices to inform landlord-focused initiatives. Approach or Design: Five focus groups were conducted with landlords. Boston, Massachusetts. Section 8 landlords participated in focus groups (n = 39). Focus group transcripts were coded for key themes using a grounded theory approach. Landlords' primary challenges to creating a healthy housing environment included tenant behavior, financial burden, and policy enforcement; tenant safety and cost savings were seen as primary benefits. Landlords play a critical role in implementing healthy housing practices. Several opportunities exist to reduce barriers and capitalize on perceived benefits of implementing these practices, including increasing access to educational and financial resources.

Previous studies exploring the prevalence of depression among South Asians reported inconsistent findings. Research artefacts due to sampling bias, measurements errors and a failure to include ethnographic methods may all explain this. We estimated the prevalence of depression, and variations of prevalence with culture, cultural adaptation, somatic symptoms and physical disability in a cross-sectional primary care survey of Punjabi and English attendees. We included a culture specific screening instrument, culturally adapted the instruments and offered bilingual interviews. We found that, compared with their English counterparts, depressive diagnoses were more common among Punjabis, Punjabi women, Punjabis with physical complaints and, contrary to expectation, even Punjabis with low scores for somatic symptoms.

Traumatic injury caused by explosive or blast events is traditionally divided into four mechanisms: primary, secondary, tertiary, and quaternary blast injury. The mechanisms of blast-induced traumatic brain injury (bTBI) are biomechanically distinct and can be modeled in both in vivo and in vitro systems. The primary bTBI injury mechanism is associated with the response of brain tissue to the initial blast wave. Among the four mechanisms of bTBI, there is a remarkable lack of information regarding the mechanism of primary bTBI. On the other hand, 30 years of research on the medical application of shock waves (SWs) has given us insight into the mechanisms of tissue and cellular damage in bTBI, including both air-mediated and underwater SW sources. From a basic physics perspective, the typical blast wave consists of a lead SW followed by shock-accelerated flow. The resultant tissue injury includes several features observed in primary bTBI, such as hemorrhage, edema, pseudo-aneurysm formation, vasoconstriction, and induction of apoptosis. These are well-described pathological findings within the SW literature. Acoustic impedance mismatch, penetration of tissue by shock/bubble interaction, geometry of the skull, shear stress, tensile stress, and subsequent cavitation formation are all important factors in determining the extent of SW-induced tissue and cellular injury. In addition, neuropsychiatric aspects of blast events need to be taken into account, as evidenced by reports of comorbidity and of some similar symptoms between physical injury resulting in bTBI and the psychiatric sequelae of post-traumatic stress. Research into blast injury biophysics is important to elucidate specific pathophysiologic mechanisms of blast injury, which enable accurate differential diagnosis, as well as development of effective treatments. Herein we describe the requirements for an adequate experimental setup when investigating blast-induced tissue and cellular injury; review SW physics, research, and the importance of engineering validation (visualization/pressure measurement/numerical simulation); and, based upon our findings of SW-induced injury, discuss the potential underlying mechanisms of primary bTBI.

Getting the results of research implemented into routine healthcare is often a challenge. The disconnect between the development and implementation of evidence into practice is called the 'second translational gap' and is particularly apparent in primary care. To address this gap, we plan to identify, summarise and synthesise currently available evidence by undertaking a systematic review of reviews to: (1) explore barriers and facilitators of implementation of research evidence or complex interventions, and (2) assess the effectiveness of strategies in facilitating implementation of complex interventions in primary care. This is a protocol for a systematic review of reviews. We will search MEDLINE, EMBASE, the Cochrane Library, CINAHL and PsycINFO up until December 2013. We will check reference lists of included studies for further studies. Two authors will independently screen the titles and abstracts identified from the search; any discrepancies will be resolved by discussion and consensus. Full-text papers will be obtained and relevant reviews will be selected against inclusion criteria. Eligible reviews have to be based on predominantly primary care in developed countries and examine either factors to implementation or, the effectiveness of strategies to optimise implementation. Data from eligible reviews will be extracted using standardised data abstraction forms. For barriers and facilitators, data will be synthesised using an interpretative meta-synthesis approach. For implementation strategies, findings will be summarised and described narratively and synthesised using a framework approach. All findings will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Ethical approval is not required. The review findings will inform the work of the design and implementation of future studies and will be of interest to a wide audience including health professionals, researchers, health service or commissioning managers and policymakers.

Many people with clinically significant chronic obstructive pulmonary disease (COPD) remain undiagnosed worldwide. There are a number of small studies which have examined possible methods of case finding through primary care, but no large RCTs that have adequately assessed the most cost-effective approach. In this study, using a cluster randomised controlled trial (RCT) in 56 general practices in the West Midlands, we plan to investigate the effectiveness and cost-effectiveness of a Targeted approach to case finding for COPD compared with routine practice. Using an individual patient RCT nested in the Targeted arm, we plan also to compare the effectiveness and cost-effectiveness of Active case finding using a postal questionnaire (with supplementary opportunistic questionnaires), and Opportunistic-only case finding during routine surgery consultations.All ever-smoking patients aged 40-79 years, without a current diagnosis of COPD and registered with participating practices will be eligible. Patients in the Targeted arm who report positive respiratory symptoms (chronic cough or phlegm, wheeze or dyspnoea) using a brief questionnaire will be invited for further spirometric assessment to ascertain whether they have COPD or not. Post-bronchodilator spirometry will be conducted to ATS standards using an Easy One spirometer by trained research assistants.The primary outcomes will be new cases of COPD and cost per new case identified, comparing targeted case finding with routine care, and two types of targeted case finding (active versus opportunistic). A multilevel logistic regression model will be used to model the probability of detecting a new case of COPD for each treatment arm, with clustering of patients (by practice and household) accounted for using a multi-level structure.A trial-based analysis will be undertaken using costs and outcomes collected during the trial. Secondary outcomes include the feasibility, efficiency, long-term cost-effectiveness, patient and primary care staff views of each approach. This will be the largest RCT of its kind, and should inform how best to identify undiagnosed patients with COPD in the UK and other similar healthcare systems. Sensitivity analyses will help local policy-makers decide which sub-groups of the population to target first. Current controlled trials ISRCTN14930255.

Models of clinical reasoning with a focus on general practice: A critical review.
Yazdani, Shahram; Hosseinzadeh, Mohammad; Hosseini, Fakhrolsadat
2017-10-01
Diagnosis lies at the heart of general practice. Every day general practitioners (GPs) visit patients with a wide variety of complaints and concerns, with often minor but sometimes serious symptoms. General practice has many features which differentiate it from specialty care setting, but during the last four decades little attention was paid to clinical reasoning in general practice. Therefore, we aimed to critically review the clinical reasoning models with a focus on the clinical reasoning in general practice or clinical reasoning of general practitioners to find out to what extent the existing models explain the clinical reasoning specially in primary care and also identity the gaps of the model for use in primary care settings. A systematic search to find models of clinical reasoning were performed. To have more precision, we excluded the studies that focused on neurobiological aspects of reasoning, reasoning in disciplines other than medicine decision making or decision analysis on treatment or management plan. All the articles and documents were first scanned to see whether they include important relevant contents or any models. The selected studies which described a model of clinical reasoning in general practitioners or with a focus on general practice were then reviewed and appraisal or critics of other authors on these models were included. The reviewed documents on the model were synthesized. Six models of clinical reasoning were identified including hypothetic-deductive model, pattern recognition, a dual process diagnostic reasoning model, pathway for clinical reasoning, an integrative model of clinical reasoning, and model of diagnostic reasoning strategies in primary care. Only one model had specifically focused on general practitioners reasoning. A Model of clinical reasoning that included specific features of general practice to better help the general practitioners with the difficulties of clinical reasoning in this setting is needed.

Is hypertension predictive of clinical recurrence in posterior reversible encephalopathy syndrome?
Li, Richard; Mitchell, Peter; Dowling, Richard; Yan, Bernard
2013-02-01
Posterior reversible encephalopathy syndrome (PRES) has a distinctive clinical presentation and typical neuroimaging findings. However, data on its clinical course and recurrence are scarce. This study aims to investigate its clinical profile and factors that predict recurrence. We included patients diagnosed with PRES between 2005 and 2010 and collected data on demographics, presenting symptoms, co-morbidities, risk factors, clinical parameters, MRI findings, complications and recurrence. Patients were categorized into two groups: PRES due to primary hypertension and PRES due to secondary causes. Correlation with presenting symptoms, radiological features, and recurrence were analyzed. PRES was identified in 28 patients. Fourteen (50%) had primary hypertension. Secondary causes included immunosuppression-related (39%), preeclampsia/eclampsia (7%), and marijuana-intake-related (4%) causes. Patients presented with altered mental status (79%), headache (75%), seizure (68%), visual disturbance (39%) and hemiparesis (21%). On MRI 93% had the typical parietal-occipital involvement. The frontal lobe was affected in 64%, cerebellum in 29%, brainstem in 21%, and basal ganglia in 11%. About 36% had cortical involvement; 21% had diffusion-restricted lesions. Non-aneurysmal subarachnoid haemorrhage was found in 18% of patients and intracerebral hemorrhage in 14% of patients. No significant difference existed in presenting symptoms and the MRI distribution of vasogenic edema between the primary hypertension group and the secondary causes group. Recurrence occurred in four patients (14.3%, 95% confidence interval 4.2-33.7) and was significantly associated (p=0.05) with primary hypertension as the etiology. Intensive monitoring and treatment of hypertension is recommended for reducing morbidity. Copyright © 2012 Elsevier Ltd. All rights reserved.

Sclerosing cholangitis is a spectrum of chronic progressive cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts, which can be classified as primary and secondary sclerosing cholangitis. Primary sclerosing cholangitis is a chronic progressive liver disease of unknown cause. On the other hand, secondary sclerosing cholangitis has identifiable causes that include immunoglobulin G4-related sclerosing disease, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndrome-related cholangitis, and eosinophilic cholangitis. In this review, we suggest a systemic approach to the differential diagnosis of sclerosing cholangitis based on the clinical and laboratory findings, as well as the typical imaging features on computed tomography and magnetic resonance (MR) imaging with MR cholangiography. Familiarity with various etiologies of sclerosing cholangitis and awareness of their typical clinical and imaging findings are essential for an accurate diagnosis and appropriate management.

This study investigates the relationship, if any, between teacher participation in a targeted professional development programme and changes in participants' instructional practice and their pupils' attitudes to learning primary science. The programme took place over a 2-year period in 15 small rural schools in the West of Ireland. Data sources include teacher and pupil questionnaires, semi-structured interviews and informal classroom observations. The findings reveal that as a result of their involvement in the programme, (a) teachers' instructional practice in science lessons became more inquiry-based and they were engaging their pupils in substantially more hands-on activities in science lessons and (b) pupils developed more positive attitudes towards learning science. The findings from this study add to what is known about delivering effective professional development.

Background Mutations in the glucocerebrosidase (GBA) gene are associated with Lewy body (LB) disorders. Objective To determine the relationship of GBA mutations and APOE4 genotype to LB and Alzheimer disease (AD) pathological findings. Design Case-control study. Setting Academic research. Participants The 187 subjects included patients with primary neuropathological diagnoses of LB disorders with or without AD changes (95 cases), randomly selected patients with AD (without significant LB pathological findings; 60 cases), and controls with neither LB nor AD pathological findings (32 cases). Main Outcome Measures GBA mutation status, APOE4 genotype, LB pathological findings (assessed according to the third report of the Dementia With Lewy Body Consortium), and Alzheimer plaque and tangle pathological findings (rated by criteria of Braak and Braak, the Consortium to Establish a Registry for Alzheimer Disease, and the National Institute on Aging–Reagan Institute). Results GBA mutations were found in 18% (34 of 187) of all subjects, including 28% (27 of 95) of those with primary LB pathological findings compared with 10% (6 of 60) of those with AD pathological findings and 3% (1 of 32) of those without AD or LB pathological findings (P=.001). GBA mutation status was significantly associated with the presence of cortical LBs (odds ratio, 6.48; 95% confidence interval, 2.45–17.16; P<.001), after adjusting for sex, age at death, and presence of APOE4. GBA mutation carriers were significantly less likely to meet AD pathological diagnostic (National Institute on Aging–Reagan Institute intermediate or high likelihood) criteria (odds ratio, 0.35; 95% confidence interval, 0.15–0.79; P=.01) after adjustment for sex, age at death, and APOE4. Conclusion GBA mutations may be associated with pathologically “purer” LB disorders, characterized by more extensive (cortical) LB, and less severe AD pathological findings and may be a useful marker for LB disorders.

Background We summarize the findings of assessments of projects, programs, and research studies (collectively referred to as projects) included in a larger review of the effectiveness of community–based primary health care (CBPHC) in improving maternal, neonatal and child health (MNCH). Findings on neonatal and child health are reported elsewhere in this series. Methods We searched PUBMED and other databases through December 2015, and included assessments that underwent data extraction. Data were analyzed to identify themes in interventions implemented, health outcomes, and strategies used in implementation. Results 152 assessments met inclusion criteria. The majority of assessments were set in rural communities. 72% of assessments included 1–10 specific interventions aimed at improving maternal health. A total of 1298 discrete interventions were assessed. Outcome measures were grouped into five main categories: maternal mortality (19% of assessments); maternal morbidity (21%); antenatal care attendance (50%); attended delivery (66%) and facility delivery (69%), with many assessments reporting results on multiple indicators. 15 assessments reported maternal mortality as a primary outcome, and of the seven that performed statistical testing, six reported significant decreases. Seven assessments measured changes in maternal morbidity: postpartum hemorrhage, malaria or eclampsia. Of those, six reported significant decreases and one did not find a significant effect. Assessments of community–based interventions on antenatal care attendance, attended delivery and facility–based deliveries all showed a positive impact. The community–based strategies used to achieve these results often involved community collaboration, home visits, formation of participatory women’s groups, and provision of services by outreach teams from peripheral health facilities. Conclusions This comprehensive and systematic review provides evidence of the effectiveness of CBPHC in improving key indicators of maternal morbidity and mortality. Most projects combined community– and facility–based approaches, emphasizing potential added benefits from such holistic approaches. Community–based interventions will be an important component of a comprehensive approach to accelerate improvements in maternal health and to end preventable maternal deaths by 2030. PMID:28685040

The molecular alterations of pancreatic acinar cell carcinomas (ACCs) are poorly understood and have been reported as being different from those in ductal adenocarcinomas. Loss of TP53 gene function in the pathogenesis of ACCs is controversial since contradictory findings have been published. A comprehensive analysis of the different possible genetic and epigenetic mechanisms leading to TP53 alteration in ACC has never been reported and hence the role of TP53 in the pathogenesis and/or progression of ACC remains unclear. We investigated TP53 alterations in 54 tumor samples from 44 patients, including primary and metastatic ACC, using sequencing analysis, methylation-specific multiplex ligation probe amplification, fluorescence in situ hybridization, and immunohistochemistry. TP53 mutations were found in 13 % of primary ACCs and in 31 % of metastases. Primary ACCs and metastases showed the same mutational profile, with the exception of one case, characterized by a wild-type sequence in the primary carcinoma and a mutation in the corresponding metastasis. FISH analysis revealed deletion of the TP53 region in 53 % of primary ACCs and in 50 % of metastases. Promoter hypermethylation was found in one case. The molecular alterations correlated well with the immunohistochemical findings. A statistically significant association was found between the combination of mutation of one allele and loss of the other allele of TP53 and worse survival.

Ultrasonography (USG) and technetium-99m sestamibi (MIBI) scintigraphy are commonly used imaging modalities in the era of minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism (pHPT). However, their relative importance and actual contribution to MIP have not been prospectively assessed. A total of 100 consecutive pHPT patients planning for MIP were recruited. Both USG and MIBI findings were correlated with intraoperative findings and postoperative outcome. Clinicopathologic factors were examined for potential association with a correct localizing result. Thirty men and 70 women (age range 13 to 93 years [median 55.5]) were included in the study. The final pathology included 98 patients with solitary adenoma and 2 patients with multiglandular disease. The sensitivities, accuracies, and positive predicted values for USG and MIBI alone were 57% vs 89%, 56% vs 85%, and 97% vs 94%, respectively. Correctly localized adenomas were significantly heavier than incorrectly localized ones. MIBI is preferred over USG in pHPT patients planning for MIP. Weight of adenoma appeared to be the only clinicopathologic factor determining localization accuracy.

Breathlessness in the primary care setting.
Baxter, Noel
2017-09-01
Breathlessness is a high-volume problem with 10% of adults experiencing the symptom daily placing a heavy burden on the health and wider economy. As it worsens, they enter the specialist and hospital-based symptom services where costs quickly escalate and people may find themselves in a place not of their choosing. For many, their care will be delivered by a disease or organ specialist and can find themselves passing between physicians without coordination for symptom support. General practitioners (GPs) will be familiar with this scenario and can often feel out of their depth. Recent advances in our thinking about breathlessness symptom management can offer opportunities and a sense of hope when the GP is faced with this situation. Original research, reviews and other findings over the last 12-18 months that pertain to the value that general practice and the wider primary care system can add, include opportunities to help people recognize they have a problem that can be treated. We present systems that support decisions made by primary healthcare professionals and an increasingly strong case that a solution is required in primary care for an ageing and frail population where breathlessness will be common. Primary care practitioners and leaders must start to realize the importance of recognizing and acting early in the life course of the person with breathlessness because its impact is enormous. They will need to work closely with public health colleagues and learn from specialists who have been doing this work usually with people near to the end of life translating the skills and knowledge further upstream to allow people to live well and remain near home and in their communities.

Measuring value for money: a scoping review on economic evaluation of health information systems.
Bassi, Jesdeep; Lau, Francis
2013-01-01
To explore how key components of economic evaluations have been included in evaluations of health information systems (HIS), to determine the state of knowledge on value for money for HIS, and provide guidance for future evaluations. We searched databases, previously collected papers, and references for relevant papers published from January 2000 to June 2012. For selection, papers had to: be a primary study; involve a computerized system for health information processing, decision support, or management reporting; and include an economic evaluation. Data on study design and economic evaluation methods were extracted and analyzed. Forty-two papers were selected and 33 were deemed high quality (scores ≥ 8/10) for further analysis. These included 12 economic analyses, five input cost analyses, and 16 cost-related outcome analyses. For HIS types, there were seven primary care electronic medical records, six computerized provider order entry systems, five medication management systems, five immunization information systems, four institutional information systems, three disease management systems, two clinical documentation systems, and one health information exchange network. In terms of value for money, 23 papers reported positive findings, eight were inconclusive, and two were negative. We found a wide range of economic evaluation papers that were based on different assumptions, methods, and metrics. There is some evidence of value for money in selected healthcare organizations and HIS types. However, caution is needed when generalizing these findings. Better reporting of economic evaluation studies is needed to compare findings and build on the existing evidence base we identified.

Care in the country: a historical case study of long-term sustainability in 4 rural health centers.
Wright, D Brad
2009-09-01
From 1978 to 1983, researchers at the University of North Carolina conducted a National Evaluation of Rural Primary Care Programs. Thirty years later, many of the programs they studied have closed, but the challenges of providing rural health care have persisted. I explored the histories of 4 surviving rural primary care programs and identified factors that contributed to their sustainability. These included physician advocates, innovative practices, organizational flexibility, and community integration. As rural health programs look ahead, identifying future generations of physician advocates is a crucial next step in developing the rural primary care workforce. It is also important for these programs to find ways to cope with high rates of staff turnover.

To evaluate whole body computed tomography (CT) for staging canine appendicular osteosarcoma. Retrospective case series. Client-owned dogs diagnosed with appendicular osteosarcoma (n=39). Medical records for client-owned dogs diagnosed with appendicular osteosarcoma from August 2008 to July 2014 were reviewed. Dogs were included if they had a confirmed diagnosis of appendicular osteosarcoma and were staged using whole body CT. Data collected included signalment, body weight, primary tumor location, serum alkaline phosphatase (ALP) activity, findings on 3-view thoracic radiographs, cytologic or histologic results, and findings on CT. Thirty-nine dogs (median age 8.5 years; median body weight 37 kg) had osteosarcoma of the distal radius (n=17), proximal humerus (11) and other sites. Serum ALP activity was elevated in 14 dogs. Bone metastasis was not detected in any dog on whole body CT. Pulmonary metastasis was considered definitive on CT based on board certified radiologist assessment in 2/39 dogs (5%). Two additional dogs (2/39, 5%) had soft tissue masses diagnosed on CT, consistent with concurrent, non-metastatic malignancies. Bone metastases were not identified in any dog with whole body CT. Thoracic and abdominal CT detected lung lesions and concurrent neoplasia in dogs with primary appendicular osteosarcoma. Whole body CT may be a useful adjunct to other screening tests for disseminated malignancy. © 2016 The American College of Veterinary Surgeons.

Recently it has been recommended that all cirrhotic patients without previous variceal hemorrhage undergo endoscopic screening to detect varices and that those with large varices should be treated with beta-blockers (American College of Gastroenterology guidelines). However, endoscopic screening only of patients at highest risk for varices may be the most cost effective. Ninety-eight patients without a history of variceal hemorrhage underwent esophagogastroduodenoscopy as part of a liver transplant evaluation. Univariate/multivariate analysis was used to evaluate associations between the presence of varices and patient characteristics including etiology of liver disease, Child-Pugh class, physical findings (spider angiomata, splenomegaly, and ascites), encephalopathy, laboratory parameters (prothrombin time, albumin, bilirubin, BUN, creatinine, and platelets), and abdominal ultrasound findings (portal vein diameter/flow, splenomegaly, and ascites). The causes of cirrhosis among the 67 men and 31 women (mean age, 48 yr) included 28% Hepatitis C/alcoholism, 25% Hepatitis C, 13% alcoholism, 9% primary sclerosing cholangitis/primary biliary cirrhosis, 9% cryptogenic, 6% Hepatitis B, 1% Hepatitis B and C, and 9% other. Patients were Child-Pugh class A 34%, B 51%, and C 15%. Endoscopic findings included esophageal varices in 68% of patients (30% were large), gastric varices in 15%, and portal hypertensive gastropathy in 58%. Platelet count <88,000 was the only parameter identified by univariate/multivariate analysis (p < 0.05) as associated with the presence of large esophageal varices (odds ratio 5.5; 95% confidence interval 1.8-20.6) or gastric varices (odds ratio 5; 95% confidence interval 1.4-23). Platelet count <88,000 is associated with the presence of esophagogastric varices. A large prospective study is needed to verify and validate these findings and may allow identification of a group of patients who would most benefit from endoscopic screening for varices.

The decision to make protocols of phase III randomized controlled trials (RCTs) publicly accessible by leading journals was a landmark event in clinical trial reporting. Here, we compared primary outcomes defined in protocols with those in publications describing the trials and in trial registration. We identified phase III RCTs published between January 1, 2012, and June 30, 2015, in The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, and The BMJ with available protocols. Consistency in primary outcomes between protocols and registries (articles) was evaluated. We identified 299 phase III RCTs with available protocols in this analysis. Out of them, 25 trials (8.4%) had some discrepancy for primary outcomes between publications and protocols. Types of discrepancies included protocol-defined primary outcome reported as nonprimary outcome in publication (11 trials, 3.7%), protocol-defined primary outcome omitted in publication (10 trials, 3.3%), new primary outcome introduced in publication (8 trials, 2.7%), protocol-defined nonprimary outcome reported as primary outcome in publication (4 trials, 1.3%), and different timing of assessment of primary outcome (4 trials, 1.3%). Out of trials with discrepancies in primary outcome, 15 trials (60.0%) had discrepancies that favored statistically significant results. Registration could be seen as a valid surrogate of protocol in 237 of 299 trials (79.3%) with regard to primary outcome. Despite unrestricted public access to protocols, selective outcome reporting persists in a small fraction of phase III RCTs. Only studies from four leading journals were included, which may cause selection bias and limit the generalizability of this finding. Copyright © 2017 Elsevier Inc. All rights reserved.

The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a quality of life (QOL) assessment tool that was originally developed for use in patients with primary brain tumors. However, the tool has also been used to assess QOL in patients with metastatic brain tumors. The purpose of this study is to compare the differences in QOL responses as assessed by the FACT-Br in patients with primary and metastatic brain neoplasms. A systematic literature search was conducted using the OvidSP platform in MEDLINE (1946 to July Week 2 2012) and EMBASE (1980 to 2012 Week 28). Articles in which the FACT-Br was used as a QOL assessment for patients with malignant brain tumors (both primary and metastatic) were included in the study. The weighted means of FACT-Br subscale and overall scores were calculated for the studies. To compare these scores, weighted analysis of variance was conducted and PROC GLM was performed for the data. A P-value of < 0.05 was considered statistically significant. A total of 23 studies (four in brain metastases, 18 in primary brain tumors and 1 in a mixed sample) using the FACT-Br for assessment of QOL were identified. Social and functional well-being were significantly better in patients with primary brain tumors (weighted mean score of 22.2 vs. 10.7, P = 0.0026, 16.9 vs. 6.2, P = 0.0025, respectively). No other scale of the FACT-Br was significantly different between the two groups and the performance status of patients included in both groups was similar. Patients with primary brain cancer seemed to have better social and functional well-being scores than those with metastatic brain tumors. Other QOL domains were similar between these two groups. However, the heterogeneity in the included studies and the low sample size of included samples in patients with metastatic brain tumors could have confounded our findings.

While some research has been conducted examining recruitment methods to engage physicians and practices in primary care research, further research is needed on recruitment methodology as it remains a recurrent challenge and plays a crucial role in primary care research. This paper reviews recruitment strategies, common challenges, and innovative practices from five recent primary care health services research studies in Ontario, Canada. We used mixed qualitative and quantitative methods to gather data from investigators and/or project staff from five research teams. Team members were interviewed and asked to fill out a brief survey on recruitment methods, results, and challenges encountered during a recent or ongoing project involving primary care practices or physicians. Data analysis included qualitative analysis of interview notes and descriptive statistics generated for each study. Recruitment rates varied markedly across the projects despite similar initial strategies. Common challenges and creative solutions were reported by many of the research teams, including building a sampling frame, developing front-office rapport, adapting recruitment strategies, promoting buy-in and interest in the research question, and training a staff recruiter. Investigators must continue to find effective ways of reaching and involving diverse and representative samples of primary care providers and practices by building personal connections with, and buy-in from, potential participants. Flexible recruitment strategies and an understanding of the needs and interests of potential participants may also facilitate recruitment.

Promoting physical activity among older people in primary care using peer mentors.
Stevens, Zoe; Barlow, Cate; Iliffe, Steve
2015-04-01
The home-based Otago Exercise Programme has been shown to increase sustained physical-activity levels in older people recruited through primary care, when supported by health professionals. The ProAct65+ trial is testing this programme using volunteer peer mentors to support behaviour change. This qualitative study explored how these peer mentors experienced their role. Ten peer mentors from the ProAct65+ trial were interviewed. Semi-structured interviews were audio-recorded, transcribed verbatim and thematically analysed. Peer mentors reported positive experiences including meeting new people, watching mentees progress, developing friendships and being shown gratitude for their support. Key barriers and facilitators to the mentoring process included the home and telephone as settings for support, geography and making contact with mentees. Findings from this study can help the development of peer mentor programmes in primary care for older people. Future programmes should recruit peer mentors who are local to where mentoring is needed to reduce travel difficulties.

Yates, Lucy R.; Gerstung, Moritz; Knappskog, Stian
Sequencing cancer genomes may enable tailoring of therapeutics to the underlying biological abnormalities driving a particular patient's tumor. However, sequencing-based strategies rely heavily on representative sampling of tumors. To understand the subclonal structure of primary breast cancer, we applied whole-genome and targeted sequencing to multiple samples from each of 50 patients' tumors (303 samples in total). The extent of subclonal diversification varied among cases and followed spatial patterns. No strict temporal order was evident, with point mutations and rearrangements affecting the most common breast cancer genes, including PIK3CA, TP53, PTEN, BRCA2 and MYC, occurring early in some tumors and latemore » in others. In 13 out of 50 cancers, potentially targetable mutations were subclonal. Landmarks of disease progression, such as resistance to chemotherapy and the acquisition of invasive or metastatic potential, arose within detectable subclones of antecedent lesions. These findings highlight the importance of including analyses of subclonal structure and tumor evolution in clinical trials of primary breast cancer.« less

This paper describes development of a prototype data analytics portal for analysis of accumulated screening results from eCHAT (electronic Case-finding and Help Assessment Tool). eCHAT allows individuals to conduct a self-administered lifestyle and mental health screening assessment, with usage to date chiefly in the context of primary care waiting rooms. The intention is for wide roll-out to primary care clinics, including secondary school based clinics, resulting in the accumulation of population-level data. Data from a field trial of eCHAT with sexual health questions tailored to youth were used to support design of a data analytics portal for population-level data. The design process included user personas and scenarios, screen prototyping and a simulator for generating large-scale data sets. The prototype demonstrates the promise of wide-scale self-administered screening data to support a range of users including practice managers, clinical directors and health policy analysts.

Existing literature on the marketing of primary healthcare services was reviewed to determine the role of registered nurses in this regard. The systematic review included five searches and ensured wide coverage of the results of available primary research studies on the topic. The results were summarised and the role of registered nurses in the marketing of primary healthcare services was identified. Primary research sources on the topic included textbooks on marketing by experts in the field and relevant journal articles by authorities on healthcare marketing. The data were analysed and four main categories identified. To ensure the trustworthiness of the research, Lincoln and Guba's (1981: 215-216) criteria, as explained by Krefting (1991: 217), were applied. Because the population consisted of only literature, ethical considerations concerning human subjects were irrelevant. Results indicated that the basic commercial marketing principles (the so-called 4Ps--product, price, place, and promotion) could be adapted for the health sector. The conclusion was that registered nurses could contribute to the marketing of primary healthcare services by communicating with the community (promotion) and by ensuring effective service (product) delivery at the right price and place. Registered nurses could influence the community's perceptions of health care and facilitate behaviour changes, thereby promote health. The implementation of the findings and recommendations of this research could create a new awareness among registered nurses of their role in the marketing of primary healthcare services in South Africa and improve their skills in this regard.

This study explored whether valproic acid (VPA, a histone deacetylase inhibitor) could radiosensitize osteosarcoma and primary-culture tumor cells, and determined the mechanism of VPA-induced radiosensitization. The working system included osteosarcoma cells (U2OS) and primary-culture cells from chemical carcinogen (DMBA)-induced breast cancer in rats; and clonogenic survival, immunofluorescence, fluorescent in situ hybridization (FISH) for chromosome aberrations, and comet assays were used in this study. It was found that VPA at the safe or critical safe concentration of 0.5 or 1.0 mM VPA could result in the accumulation of more ionizing radiation (IR)-induced DNA double strand breaks, and increase the cell radiosensitivity. VPA-induced radiosensitivity was associated with the inhibition of DNA repair activity in the working systems. In addition, the chromosome aberrations including chromosome breaks, chromatid breaks, and radial structures significantly increased after the combination treatment of VPA and IR. Importantly, the results obtained by primary-culture cells from the tissue of chemical carcinogen-induced breast cancer in rats further confirmed our findings. The data in this study demonstrated that VPA at a safe dose was a radiosensitizer for osteosarcoma and primary-culture tumor cells through suppressing DNA-double strand breaks repair function.

Few studies have been published reporting risk factors for flap necrosis after primary palatoplasty in patients with cleft palate. This complication is rare, and the event is a disaster for both the patient and the surgeon. This study was performed to explore the associations between different risk factors and the development of flap necrosis after primary palatoplasty in patients with cleft palate. This is a case-control study. A 20 years retrospective analysis (1994-2015) of patients with nonsyndromic cleft palate was identified from medical records and screening day registries). Demographical and risk factor data were collected using a patient´s report, including information about age at surgery, gender, cleft palate type, and degree of severity. Odds ratios and 95% confident intervals were derived from logistic regression analysis. All cases with diagnoses of flap necrosis after primary palatoplasty were included in the study (48 patients) and 156 controls were considered. In multivariate analysis, female sex, age (older than 15 years), cleft type (bilateral and incomplete), and severe cleft palate index were associated with significantly increased risk for flap necrosis. The findings suggest that female sex, older age, cleft type (bilateral and incomplete), and severe cleft palatal index may be associated with the development of flap necrosis after primary palatoplasty in patients with cleft palate.

Freshwaters in the Athabasca Oil Sands Region (AOSR) are vulnerable to the atmospheric emissions and land disturbances caused by the local oil sands industry; however, they are also affected by climate change. Recent observations of increases in aquatic primary production near the main development area have prompted questions about the principal drivers of these limnological changes. Is the enhanced primary production due to deposition of nutrients (nitrogen and phosphorus) from local industry or from recent climatic changes? Here, we use downcore, spectrally-inferred chlorophyll-a (VRS-chla) profiles (including diagenetic products) from 23 limnologically-diverse lakes with undisturbed catchments to characterize the pattern of primary production increases in the AOSR. Our aim is to better understand the relative roles of the local oil sands industry versus climate change in driving aquatic primary production trends. Nutrient deposition maps, generated using geostatistical interpolations of spring-time snowpack measurements from a grid pattern across the AOSR, demonstrate patterns of elevated total phosphorus, total nitrogen, and bioavailable nitrogen deposition around the main area of industrial activity. However, this pattern is not observed for bioavailable phosphorus. Our paleolimnological findings demonstrate consistently greater VRS-chla concentrations compared to pre-oil sands development levels, regardless of morphological and limnological characteristics, landscape position, bioavailable nutrient deposition, and dibenzothiophene (DBT)-inferred industrial impacts. Furthermore, breakpoint analyses on VRS-chla concentrations across a gradient of DBT-inferred industrial impact show limited evidence of a contemporaneous change among lakes. Despite the contribution of bioavailable nitrogen to the landscape from industrial activities, we find no consistency in the spatial pattern and timing of VRS-chla shifts with an industrial fertilizing signal. Instead, significant positive correlations were observed between VRS-chla and annual and seasonal temperatures. Our findings suggest warmer air temperatures and likely decreased ice covers are important drivers of enhanced aquatic primary production across the AOSR. PMID:27135946

Background: Childhood obesity is a world-wide health problem and development of interventions to prevent or control it is a priority. Obesity is prevalent and on the increase among school-students in Iran, too. As the first step for development of an intervention, the current study was designed to complete our understanding of ideas, attitudes, beliefs, and preferences of primary school children in Tehran, Iran. Methods: Twenty-seven primary school-students (11 boys, 16 girls) in grade-five, most of whom were overweight or obese, participated in four focus-group discussions (FGDs). All FGD notes were analyzed to find the main themes. Results: Nine themes in three main categories emerged after analysis. The themes in the category of barriers of losing weight included environmental, psychological and physiological barriers. Category of intervention components included nutrition improvement, physical activity promotion, social support and education. Setting and deliverer of the intervention were included in the intervention conditions category. The children proposed a multi-component approach for development of an intervention. They mentioned nutrition and physical activity improvement, social support and education as the main elements of an effective intervention. Conclusions: The findings indicate that obese children need to be supported against different barriers of losing weight, mainly social barriers, especially humiliation by the community. PMID:25489443

From favours to entitlements: community voice and action and health service quality in Zambia

Abstract Social accountability is increasingly invoked as a way of improving health services. This article presents a theory-driven qualitative study of the context, mechanisms and outcomes of a social accountability program, Citizen Voice and Action (CVA), implemented by World Vision (WV) in Zambia. Primary data were collected between November 2013 and January 2014. It included in-depth interviews and focus group discussions with program stakeholders. Secondary data were used iteratively—to inform the process for primary data collection, to guide primary data analysis and to contextualize findings from the primary data. CVA positively impacted the state, society, state–society relations and development coordination at the local level. Specifically, sustained improvements in some aspects of health system responsiveness, empowered citizens, the improved provision of public goods (health services) and increased consensus on development issues appeared to flow from CVA. The central challenge described by interviewees and FGD participants was the inability of CVA to address problems that required central level input. The mechanisms that generated these outcomes included productive state–society communication, enhanced trust, and state–society co-production of priorities and the provision of services. These mechanisms were activated in the context of existing structures for state–society interaction, willing political leaders, buy-in by traditional leaders, and WV’s strong reputation and access to resources. Prospective observational research in multiple contexts would shed more light on the context, mechanisms and outcomes of CVA programs. In addition to findings that are intuitive and well supported in the literature we identified new areas that are promising areas for future research. These include (1) the context of organizational reputation by the organization(s) spearheading social accountability efforts; (2) the potential relationship between social accountability efforts and making ambitious national programs operational at the frontlines of the health system and (3) the feasibility of scale up for certain types of local level responsiveness.

Changes in healthcare practice toward more proactive clinical, organizational and interprofessional working require primary healthcare professionals to learn continuously from each other through collaboration. This systematic review uses realist methodology to consolidate knowledge on the characteristics of workplace learning (WPL) through collaboration by primary healthcare professionals. Following several scoping searches, five electronic bibliographic databases were searched from January 1990 to December 2015 for relevant gray and published literature written in English, French, German and Dutch. Reviewers worked in pairs to identify relevant articles. A set of statements, based on the findings of our scoping searches, was used as a coding tree to analyze the papers. Interpretation of the results was done in alternating pairs, discussed within the author group and triangulated with stakeholders' views. Out of 6930 references, we included 42 publications that elucidated who, when, how and what primary healthcare professionals learn through collaboration. Papers were both qualitative and quantitative in design, and focused largely on WPL of collaborating general practitioners and nurses. No striking differences between different professionals within primary healthcare were noted. Professionals were often unaware of the learning that occurs through collaboration. WPL happened predominantly through informal discussions about patient cases and modeling for other professionals. Any professionals could both learn and facilitate others' learning. Outcomes were diverse, but contextualized knowledge seemed to be important. Primary care professionals' WPL is multifaceted. Existing social constructivist and social cognitivist learning theories form a framework from which to interpret these findings. Primary care policy makers and managers should ensure that professionals have access to protected time, earmarked for learning. Time is required for reflection, to learn new ways of interaction and to develop new habits within clinical practice.

Performance of primary repair on colon injuries sustained from low-versus high-energy projectiles.
Lazovic, Ranko; Radojevic, Nemanja; Curovic, Ivana
2016-04-01
Among various reasons, colon injuries may be caused by low- or high-energy firearm bullets, with the latter producing a temporary cavitation phenomenon. The available treatment options include primary repair and two-stage management, but recent studies have shown that primary repair can be widely used with a high success rate. This paper investigates the differences in performance of primary repair on these two types of colon injuries. Two groups of patients who sustained colon injuries due to single gunshot wounds, were retrospectively categorized based on the type of bullet. Primary colon repair was performed in all patients selected based on the inclusion and exclusion criteria (Stone and Fabian's criteria). An almost absolute homogeneity was attained among the groups in terms of age, latent time before surgery, and four trauma indexes. Only one patient from the low-energy firearm projectile group (4%) developed a postsurgical complication versus nine patients (25.8%) from the high-energy group, showing statistically significant difference (p = 0.03). These nine patients experienced the following postsurgical complications: pneumonia, abscess, fistula, suture leakage, and one multiorgan failure with sepsis. Previous studies concluded that one-stage primary repair is the best treatment option for colon injuries. However, terminal ballistics testing determined the projectile's path through the body and revealed that low-energy projectiles caused considerably lesser damage than their high-energy counterparts. Primary colon repair must be performed definitely for low-energy short firearm injuries but very carefully for high-energy injuries. Given these findings, we suggest that the treatment option should be determined based not only on the bullet type alone but also on other clinical findings.

Comparison between the skeletal remains of Homo floresiensis and the auxological and roentgenological findings in a large Israeli cohort of patients with Laron Syndrome (LS, primary or classical GH insensitivity or resistance) revealed striking morphological similarities, including extremely small stature and reduced cranial volume. LS is an autosomal recessive disease caused by a molecular defect of the Growth Hormone (GH) receptor or in the post-receptor cascades. Epidemiological studies have shown that LS occurs more often in consanguineous families and isolates, and it has been described in several countries in South East Asia. It is our conclusion that the findings from the island of Flores, which were attributed to a new species of the genus Homo, may in fact represent a local, highly inbred, Homo sapiens population in whom a mutation for the GH receptor had occurred.

Coping with Chronic Illness in Childhood and Adolescence
Compas, Bruce E.; Jaser, Sarah S.; Dunn, Madeleine J.; Rodriguez, Erin M.
2012-01-01
Chronic illnesses and medical conditions present millions of children and adolescents with significant stress that is associated with risk for emotional and behavioral problems and interferes with adherence to treatment regimens. We review research on the role of child and adolescent coping with stress as an important feature of the process of adaptation to illness. Recent findings support a control-based model of coping that includes primary control or active coping (efforts to act on the source of stress or one’s emotions), secondary control or accommodative coping (efforts to adapt to the source of stress), and disengagement or passive coping (efforts to avoid or deny the stressor). Evidence suggests the efficacy of secondary control coping in successful adaptation to chronic illness in children and adolescents, disengagement coping is associated with poorer adjustment, and findings for primary control coping are mixed. Avenues for future research are highlighted. PMID:22224836

[Surgical therapy of segmental jejunal, primary intestinal lymphangiectasia].
Kneist, W; Drescher, D G; Hansen, T; Kreitner, K F; Lang, H
2013-06-01
Primary intestinal lymphangiectasia (PIL) is a protein-losing, exsudative gastroenteropathy causing lymphatic obstruction. Diagnosis depends on clinical examination and histological findings. Conservative treatment modalities include a low-fat diet and enteral nutritional therapy in order to reduce enteric protein loss and to improve fat metabolism. Other treatment options consist of administration of antiplasmin or octreotide to lower lymph flow and secretion. We report on a 58-year-old patient who underwent exploratory laparotomy due to a worsening physical status, recurrent chylaskos and leg oedema under conservative dietary therapy. Intraoperative findings showed a typical PIL of the jejunum about 20 cm distal to the Treitz's ligament. Histological examinations confirmed this diagnosis. One year after segmental small bowel resection (105 cm) with end-to-end anastomosis the patient is healthy, free of symptoms, has gained weight and his serum protein level has increased. Intraabdominal ascites and leg oedema have not reoccurred since.

To evaluate the presence of dry eye and primary Sjögren syndrome (SS) in patients with migraine. In total, 46 eyes of 46 patients with migraine (group 1) and 50 eyes of 50 healthy subjects (group 2) were included in this study. Detailed ophthalmologic, neurologic and rheumatologic examination were performed on all participants. Ocular surface disease index questionnaire, tear function tests, visual analog scale for pain, serologic analysis were also performed. Dry eye symptoms and findings were significantly higher and more severe in group 1 when compared with group 2. Primary SS was not found in any of the participants. The migraine lifetime duration was negatively correlated with the tear function tests while it was positively correlated with the ocular surface disease index scores. Dry eye symptoms and findings are higher in migraine patients when compared with the healthy subjects without the presence of Sjögren syndrome.

Abstract Universal health coverage provides a framework to achieve health services coverage but does not articulate the model of care desired. Comprehensive primary health care includes promotive, preventive, curative, and rehabilitative interventions and health equity and health as a human right as central goals. In Australia, Aboriginal community-controlled health services have pioneered comprehensive primary health care since their inception in the early 1970s. Our five-year project on comprehensive primary health care in Australia partnered with six services, including one Aboriginal community-controlled health service, the Central Australian Aboriginal Congress. Our findings revealed more impressive outcomes in several areas—multidisciplinary work, community participation, cultural respect and accessibility strategies, preventive and promotive work, and advocacy and intersectoral collaboration on social determinants of health—at the Aboriginal community-controlled health service compared to the other participating South Australian services (state-managed and nongovernmental ones). Because of these strengths, the Central Australian Aboriginal Congress’s community-controlled model of comprehensive primary health care deserves attention as a promising form of implementation of universal health coverage by articulating a model of care based on health as a human right that pursues the goal of health equity.

Orbitofacial Metastatic Basal Cell Carcinoma: Report of 10 Cases.
Branson, Sara V; McClintic, Elysa; Ozgur, Omar; Esmaeli, Bita; Yeatts, R Patrick
To explore the clinical features, management, and prognosis of metastatic basal cell carcinoma originating in the orbitofacial region. Ten cases of orbitofacial metastatic basal cell carcinoma were identified by searching databases at 2 institutions from 1995 to 2015. A retrospective chart review was performed. Main outcome measures included patient demographics, lesion size, location of metastases, histologic subtype, recurrence rate, time between primary tumor diagnosis and metastasis, perineural invasion, treatment modalities, and survival from time of metastasis. The median tumor size at largest dimension was 3.3 cm (range, 1.9-11.5 cm), and 6 of 10 patients had at least 1 local recurrence before metastasis (range, 0-2 recurrences). The most common sites of metastasis included the ipsilateral parotid gland (n = 6) and cervical lymph nodes (n = 5). Histologic subtypes included infiltrative (n = 5), basosquamous (n = 2), nodular (n = 1), and mixed (n = 1). The median time from primary tumor diagnosis to metastasis was 7.5 years (range, 0-13). The median survival time from diagnosis of metastasis to last documented encounter or death was 5.3 years (range, 7 months-22.8 years). Treatment regimens included surgical excision, radiotherapy, and hedgehog inhibitors. Based on our findings, the following features may be markers of high risk orbitofacial basal cell carcinoma: 1) increasing tumor size, 2) local recurrence of the primary tumor, 3) aggressive histologic subtype, and 4) perineural invasion. Screening should include close observation of the primary site and tissues in the distribution of regional lymphatics, particularly the parotid gland and cervical lymph nodes.

Purpose To describe women’s preferences for reproductive health providers as sources of primary and mental health care. Methods Secondary data analysis of the Women’s Health Care Experiences and Preferences Study, an internet survey conducted in September 2013 of 1,078 women aged 18–55 randomly sampled from a U.S. national probability panel. We estimated women’s preferred and usual sources of care (reproductive health providers, generalists, other) for various primary care and mental health care services using weighted statistics and multiple logistic regression. Main Findings Among women using healthcare in the past five years (n=981), 88% received primary and/or mental health care, including routine medical check-up (78%), urgent/acute (48%), chronic disease (27%), depression/anxiety (21%), stress (16%), and IPV (2%) visits. Of those, reproductive health providers were the source of check-up (14%), urgent/acute (3%), chronic disease (6%), depression/anxiety (6%), stress (11%), and intimate partner violence (3%) services. Preference for specific reproductive health-provided primary/mental health care services ranged from 7–20%. Among women having used primary/mental health care services (N=894), more women (1–17%) preferred than had received primary/mental health care from reproductive health providers. Nearly a quarter (22%) identified reproductive health providers as their single most preferred source of care. Contraceptive use was the strongest predictor of preference for reproductive health-provided primary/mental health care (Odds Ratios range 2.11–3.30). Conclusions Reproductive health providers are the sole source of healthcare for a substantial proportion of reproductive-aged women – the same groups at risk for unmet primary and mental health care needs. Findings have implications for reproductive health providers’ role in comprehensive women’s healthcare provision and potentially for informing patient-centered, integrated models of care in current health systems.

Working memory impairment and cardiovascular hyperarousal in young primary insomniacs.
Cellini, Nicola; de Zambotti, Massimiliano; Covassin, Naima; Sarlo, Michela; Stegagno, Luciano
2014-02-01
We investigated memory performance and cardiovascular activity in 13 primary insomniacs (PI) compared to 13 good sleepers (GS). Cardiovascular and hemodynamic measures, including heart rate, pre-ejection period, and blood pressure, were continuously recorded at rest and during two memory tasks. PI showed working memory impairment under high cognitive load, but performed as well as GS in an easy memory task. In addition, PI exhibited markers of hyperarousal both at rest and during the execution of the two tasks. However, we failed to find a clear-cut relationship between cardiovascular hyperarousal and cognitive performance in insomniacs. Our data provide further evidence of both cognitive impairment and cardiovascular hyperarousal in primary insomnia, while not supporting the hypothesis of hyperarousal as a compensatory mechanism to overcome cognitive challenges.

This paper presents perceptions of four primary school teachers from two Victorian government primary schools about the barriers and catalyst for effective practices with ICT. Findings of the semi-structured qualitative interviews confirm results of previous studies indicating that access to reliable infrastructure, adequate technical support, and time pressures are still considered to be some of the most significant barriers to successful ICT integration in public schools. Teacher interviews however also reveal that the challenges of integrating ICT in teaching and learning can be counterbalanced by a number of variables, which include: owning a laptop, having access to ongoing professional learning, sharing effective practices, drawing on student expertise and being supported by a whole-school approach to teaching and learning with ICT.

Feasibility of two modes of treatment delivery for child anxiety in primary care.
Chavira, Denise A; Drahota, Amy; Garland, Ann F; Roesch, Scott; Garcia, Maritza; Stein, Murray B
2014-09-01
In this study, we examine the feasibility of cognitive behavior therapy (CBT) for children with anxiety in primary care, using two modes of treatment delivery. A total of 48 parents and youth (8-13) with anxiety disorders were randomly assigned to receive 10-sessions of CBT either delivered by a child anxiety specialist in the primary care clinic or implemented by the parent with therapist support by telephone (i.e., face-to-face or therapist-supported bibliotherapy). Feasibility outcomes including satisfaction, barriers to treatment participation, safety, and dropout were assessed. Independent evaluators, blind to treatment condition, administered the Anxiety Disorders Interview Schedule for Children (ADIS) and the Clinical Global Impression of Improvement (CGI-I) at baseline, post-treatment and 3-month follow-up; clinical self-report questionnaires were also administered. Findings revealed high satisfaction, low endorsement of barriers, low drop out rates, and no adverse events across the two modalities. According to the CGI-I, 58.3%-75% of participants were considered responders (i.e., much or very much improved) at the various time points. Similar patterns were found for remission from "primary anxiety disorder" and "all anxiety disorders" as defined by the ADIS. Clinically significant improvement was seen on the various parent and child self-report measures of anxiety. Findings suggest that both therapy modalities are feasible and associated with significant treatment gains in the primary care setting. (clinicaltrials.gov unique identifier: NCT00769925).

Supporting Primary Care Practices in Building Capacity to Use Health Information Data
Fernald, Douglas; Wearner, Robyn; Dickinson, W. Perry
2014-01-01
Introduction: Our objective was to describe essential support resources and strategies in order to advance the pace and scope of the use of health information technology (HIT) data. Background and Context: Primary data were collected between January 2011 and October 2012. The primary study population comprised 51 primary care practices enrolled in the Colorado Beacon Consortium in western Colorado. Methods: We used qualitative methods embedded in a mixed-method evaluation: monthly narrative reports from practices; interviews with providers and staff; and focused, group discussions with quality improvement (QI) advisors and staff from the Health Information Technology Regional Extension Center. Findings: Practices valued effective support strategies to assist with using HIT, including the following: translating rules and regulations into individual practice settings; facilitating peer-to-peer connections; providing processes and tools for practice improvement; maintaining accountability and momentum; and providing local electronic health record (EHR) technical expertise. Benefits of support included improved quality measures, operational improvements, increased provider and staff engagement, and deeper understanding of EHR data. Discussion: The findings affirm the utility of practice facilitation for HIT-focused aims with personalized attention and cross-fertilization among practices for improvements. Facilitation to sustain ongoing improvements and prepare for future HIT-intensive improvement activities was highly valued. In addition to the general practice facilitator, an EHR technical expert was critical to improving practice capacity to use electronic clinical data. Collaborative learning expands the pool of mentors and teachers, who can further translate their own lessons into practical advice for their peers, yielding the emergence of a stronger sense of community among the practices. Conclusions: Using HIT more effectively in primary care will require sustained, focused efforts by practices as regulations, incentives and HIT evolve. Ongoing support for community-based practice facilitators; collaborative learning; and local, personalized EHR advisors will help practices care for patients while more effectively deploying HIT to improve care.

Barriers and facilitators in the integration of oral health into primary care: a scoping review.
Harnagea, Hermina; Couturier, Yves; Shrivastava, Richa; Girard, Felix; Lamothe, Lise; Bedos, Christophe Pierre; Emami, Elham
2017-09-25
This scoping study has been conducted to map the literature and provide a descriptive synthesis on the barriers and facilitators of the integration of oral health into primary care. Grounded in the Rainbow conceptual model and using the Levac et al six-stage framework, we performed a systematic search of electronic databases, organisational websites and grey literature from 1978 to April 2016. All publications with a focus on the integration of oral health into primary care were included except commentaries and editorials. Thematic analyses were performed to synthesise the results. From a total of 1619 citations, 58 publications were included in the review. Barrier-related themes included: lack of political leadership and healthcare policies; implementation challenges; discipline-oriented education; lack of continuity of care and services and patients' oral healthcare needs. The facilitators of integration were supportive policies and resources allocation, interdisciplinary education, collaborative practices between dental and other healthcare professionals, presence of local strategic leaders and geographical proximity. This work has advanced the knowledge on the barriers and facilitators at each integration domain and level, which may be helpful if the healthcare organisations decide to integrate oral health and dental services into primary care. The scoping review findings could be useful for both dental and medical workforce and allied primary healthcare providers. They could also guide the development of healthcare policies that support collaborative practices and patient-centred care in the field of primary care. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Progestogens have been evaluated in numerous trials and meta-analyses, many of which concluded they were effective. However, two large trials PROMISE and OPPTIMUM have recently concluded that progesterone was ineffective. This raises the possibility that earlier studies and reviews had been biased by either selective publication or selective choice of outcomes, so called "P-hacking". To compare the findings all progestogen trials and systematic reviews with those of trials with pre-registered primary outcomes which avoided selective outcome reporting. Search of PubMed, the Cochrane Library and trial registries. Registration PROSPERO CRD42016035303. Systematic reviews of randomised trials comparing progestogen with placebo in pregnancy and the individual trials included in those reviews. The subset of trials reporting a pre-registered primary outcome were compared with the totality of trials and reviews. For reviews all outcomes were included. For individual trials all outcomes reported in the systematic reviews were included. For the comparison group we recorded the registered primary outcome from trials that were either registered before they started, or registered during the recruitment phase and also double blind. Nineteen of twenty-nine meta-analyses concluded that progestogens were effective. Twenty-two trials reported their pre-registered primary outcomes. There was no effect of progesterone on primary registered dichotomous outcome RR 1.00 (95% CI 0.94-1.07). Only one of the 22 showed a nominally statistically significant benefit. When evaluated in registered double-blind trials with analysis restricted to predefined primary outcomes, progestational agents in pregnancy are ineffective.

Measuring value for money: a scoping review on economic evaluation of health information systems
Bassi, Jesdeep; Lau, Francis
2013-01-01
Objective To explore how key components of economic evaluations have been included in evaluations of health information systems (HIS), to determine the state of knowledge on value for money for HIS, and provide guidance for future evaluations. Materials and methods We searched databases, previously collected papers, and references for relevant papers published from January 2000 to June 2012. For selection, papers had to: be a primary study; involve a computerized system for health information processing, decision support, or management reporting; and include an economic evaluation. Data on study design and economic evaluation methods were extracted and analyzed. Results Forty-two papers were selected and 33 were deemed high quality (scores ≥8/10) for further analysis. These included 12 economic analyses, five input cost analyses, and 16 cost-related outcome analyses. For HIS types, there were seven primary care electronic medical records, six computerized provider order entry systems, five medication management systems, five immunization information systems, four institutional information systems, three disease management systems, two clinical documentation systems, and one health information exchange network. In terms of value for money, 23 papers reported positive findings, eight were inconclusive, and two were negative. Conclusions We found a wide range of economic evaluation papers that were based on different assumptions, methods, and metrics. There is some evidence of value for money in selected healthcare organizations and HIS types. However, caution is needed when generalizing these findings. Better reporting of economic evaluation studies is needed to compare findings and build on the existing evidence base we identified. PMID:23416247

To identify and appraise study findings on the use of mobile devices, in particular for what purposes and how, in nursing student-nurse teacher cooperation during the clinical practicum. A systematic literature search was conducted using the PubMed/Medline, CINAHL, PsycINFO and ERIC for primary empirical studies published in English. An integrative literature review was undertaken. Quality appraisal of the included studies was conducted using design-specific standardized checklists. Studies were thematically analyzed. Based on the inclusion and exclusion criteria, eleven studies were included in the review. Weaknesses in designs, samples, questionnaires and results, compromised comparison and/or generalization of the findings of the studies. Three main themes were identified: (1) features of mobile devices (2) utility of mobile devices and (3) barriers to the use of mobile devices. Problems of connectivity were the main challenges reported in the use of mobile devices. Participants used mobile devices primarily as reference tools, but less frequently as tools for reflection, assessment or cooperation during the clinical practicum. Interest in mobile device use during the clinical practicum was reported, but training and ongoing support are needed. As only a small number of eligible primary empirical studies were found, it is not possible to draw firm conclusions on the results. In the future, rigorous primary empirical studies are needed to explore the potential of mobile devices in providing a supplementary pedagogical method in nursing student-nurse teacher cooperation during the clinical practicum. Robust study designs, including experimental ones, are clearly needed to assess the effectiveness of mobile devices in nursing student-nurse teacher cooperation during the clinical practicum.

Background and Objectives: In 2007, the Québec Ministry of Health issued a policy document that specifically mandated the development of addiction treatment services including screening, brief interventions and referral (SBIR) to be delivered by primary healthcare clinics throughout Québec. The current study examined the level of implementation of SBIR one year following the end of the mandate (2007–2012). Approach: Semi-structured interviews were conducted with 45 participants from 21 primary health and social service centres throughout the province. Qualitative analysis was used to evaluate the level of success each centre had in implementing SBIR and to identify organizational measures that contributed to successful implementation. Results: The results show that Québec primary health and social service centres had limited success in their efforts to integrate SBIR into their services. A comparative analysis of the centres, categorized according to their level of implementation, revealed the presence of significant organizational- and staff-level factors, including the creation of formal action plans that were conducive to the successful implementation of SBIR in primary care. Conclusion: The findings highlight the importance of offering support and guidance, as well as a menu of specific practices that are likely to assist primary health and social services centres to implement SBIR. At the organizational level, the adoption of local action plans and formal service trajectories offers a framework that allows for horizontal and vertical integration of new practices. PMID:26742118

Background Diagnostic imaging is often the first step in evaluating patients with back pain and likely functions as a “gateway” to a subsequent cascade of interventions. However, lumbar spine imaging frequently reveals incidental findings among normal, pain-free individuals suggesting that treatment of these “abnormalities” may not be warranted. Our prior work suggested that inserting the prevalence of imaging findings in patients without back pain into spine imaging reports may reduce subsequent interventions. We are now conducting a pragmatic cluster randomized clinical trial to test the hypothesis that inserting this prevalence data into lumbar spine imaging reports for studies ordered by primary care providers will reduce subsequent spine-related interventions. Methods/Design We are using a stepped wedge design that sequentially randomizes 100 primary care clinics at four health systems to receive either standard lumbar spine imaging reports, or reports containing prevalence data for common imaging findings in patients without back pain. We capture all outcomes passively through the electronic medical record. Our primary outcome is spine-related intervention intensity based on Relative Value Units (RVUs) during the following year. Secondary outcomes include subsequent prescriptions for opioid analgesics and cross-sectional lumbar spine re-imaging. Discussion If our study shows that adding prevalence data to spine imaging reports decreases subsequent back-related RVUs, this intervention could be easily generalized and applied to other kinds of testing, as well as other conditions where incidental findings may be common. Our study also serves as a model for cluster randomized trials that are minimal risk and highly pragmatic. PMID:26493088

Magnetic resonance imaging findings of paracoccidioidomycosis in the musculoskeletal system.
Savarese, Leonor G; Monsignore, Lucas M; de Andrade Hernandes, Mateus; Martinez, Roberto; Nogueira-Barbosa, Marcello H
2015-10-01
To describe magnetic resonance imaging (MRI) findings in musculoskeletal paracoccidioidomycosis (PCM). Retrospective case series study after IRB approval. Two musculoskeletal radiologists reviewed in consensus the MRI findings of 11 patients with microbiologically and/or pathologically proven osteoarticular PCM. The MRI evaluation included discrimination of abnormalities in joints, bones and soft tissues. Mean age of patients was 29 years (10-55 years), eight men and three women. Musculoskeletal involvement was the only or the primary presentation of the disease in seven patients (63%). Osteomyelitis was the most common presentation, with seven cases (63%). Primary arthritis was found in one patient (9%). Isolated extra-articular soft tissue PCM was found in three patients: myositis (2) and subcutaneous infection (1). All cases showed regions with signal intensity higher than or similar to the signal of muscle on T1-weighted images. Penumbra sign was present in five cases (45%). T2-weighted images showed reactive soft tissue oedema in eight cases (72%). Post-gadolinium images showed peripheral (8/9) or heterogeneous (1/9) enhancement. Synovial enhancement was present in all cases of joint involvement (6/6). Lipomatosis arborescens was documented in one case of chronic knee involvement. To our knowledge, this is the first case series describing MRI findings of musculoskeletal PCM. Musculoskeletal involvement was the primary presentation of the disease in most cases, and therefore, neoplasms were initially in the differential diagnosis. Osteomyelitis was the most common presentation, often with secondary involvement of joint and or soft tissue. © 2015 John Wiley & Sons Ltd.

Analysis of street drugs in seized material without primary reference standards.
Laks, Suvi; Pelander, Anna; Vuori, Erkki; Ali-Tolppa, Elisa; Sippola, Erkki; Ojanperä, Ilkka
2004-12-15
A novel approach was used to analyze street drugs in seized material without primary reference standards. Identification was performed by liquid chromatography/time-of-flight mass spectrometry (LC/TOFMS), essentially based on accurate mass determination using a target library of 735 exact monoisotopic masses. Quantification was carried out by liquid chromatography/chemiluminescence nitrogen detection (LC/CLND) with a single secondary standard (caffeine), utilizing the detector's equimolar response to nitrogen. Sample preparation comprised dilution, first with methanol and further with the LC mobile phase. Altogether 21 seized drug samples were analyzed blind by the present method, and results were compared to accredited reference methods utilizing identification by gas chromatography/mass spectrometry and quantification by gas chromatography or liquid chromatography. The 31 drug findings by LC/TOFMS comprised 19 different drugs-of-abuse, byproducts, and adulterants, including amphetamine and tryptamine designer drugs, with one unresolved pair of compounds having an identical mass. By the reference methods, 27 findings could be confirmed, and among the four unconfirmed findings, only 1 apparent false positive was found. In the quantitative analysis of 11 amphetamine, heroin, and cocaine findings, mean relative difference between the results of LC/CLND and the reference methods was 11% (range 4.2-21%), without any observable bias. Mean relative standard deviation for three parallel LC/CLND results was 6%. Results suggest that the present combination of LC/TOFMS and LC/CLND offers a simple solution for the analysis of scheduled and designer drugs in seized material, independent of the availability of primary reference standards.

Abstract Objective This study examined women's perceptions and reported effects of routine, primary care-based interventions to increase breastfeeding. Subjects and Methods A subsample (n=67) of participants in randomized controlled trials (RCTs) completed semistructured exit interviews at 6 months postpartum. RCT arms included the following: (a) routine pre-/postnatal lactation consultant (LC) support (LC group); (b) electronic prompts (EP) guiding providers to discuss breastfeeding during prenatal care visits (EP group); (c) a combined intervention (LC+EP group); and (d) controls. Interview transcripts were coded and analyzed in MAX.qda. Results Key findings included the following: (1) Brief, non-directive assessment of feeding via postpartum interviews focused attention upon feeding practices. When coupled with breastfeeding promotion interventions, interviews promoted breastfeeding. (2) The EP and LC interventions were complementary: EPs influenced initiation, while LCs helped overcome barriers and sustain breastfeeding. (3) Prenatal intent to feed both breastmilk and formula was associated with the greatest receptivity to study messages. Conclusions Findings underscore the need for interventions across the continuum of care. Trained LCs in prenatal/postpartum settings and prenatal care providers play important complementary roles that, when coupled with brief telephone feeding assessments, may improve breastfeeding rates.

Chloroplast evolution, structure and functions
Jensen, Poul Erik
2014-01-01
In this review, we consider a selection of recent advances in chloroplast biology. These include new findings concerning chloroplast evolution, such as the identification of Chlamydiae as a third partner in primary endosymbiosis, a second instance of primary endosymbiosis represented by the chromatophores found in amoebae of the genus Paulinella, and a new explanation for the longevity of captured chloroplasts (kleptoplasts) in sacoglossan sea slugs. The controversy surrounding the three-dimensional structure of grana, its recent resolution by tomographic analyses, and the role of the CURVATURE THYLAKOID1 (CURT1) proteins in supporting grana formation are also discussed. We also present an updated inventory of photosynthetic proteins and the factors involved in the assembly of thylakoid multiprotein complexes, and evaluate findings that reveal that cyclic electron flow involves NADPH dehydrogenase (NDH)- and PGRL1/PGR5-dependent pathways, both of which receive electrons from ferredoxin. Other topics covered in this review include new protein components of nucleoids, an updated inventory of the chloroplast proteome, new enzymes in chlorophyll biosynthesis and new candidate messengers in retrograde signaling. Finally, we discuss the first successful synthetic biology approaches that resulted in chloroplasts in which electrons from the photosynthetic light reactions are fed to enzymes derived from secondary metabolism.

This study examined women's perceptions and reported effects of routine, primary care-based interventions to increase breastfeeding. A subsample (n=67) of participants in randomized controlled trials (RCTs) completed semistructured exit interviews at 6 months postpartum. RCT arms included the following: (a) routine pre-/postnatal lactation consultant (LC) support (LC group); (b) electronic prompts (EP) guiding providers to discuss breastfeeding during prenatal care visits (EP group); (c) a combined intervention (LC+EP group); and (d) controls. Interview transcripts were coded and analyzed in MAX.qda. Key findings included the following: (1) Brief, non-directive assessment of feeding via postpartum interviews focused attention upon feeding practices. When coupled with breastfeeding promotion interventions, interviews promoted breastfeeding. (2) The EP and LC interventions were complementary: EPs influenced initiation, while LCs helped overcome barriers and sustain breastfeeding. (3) Prenatal intent to feed both breastmilk and formula was associated with the greatest receptivity to study messages. Findings underscore the need for interventions across the continuum of care. Trained LCs in prenatal/postpartum settings and prenatal care providers play important complementary roles that, when coupled with brief telephone feeding assessments, may improve breastfeeding rates.

Background The Commission on the Social Determinants of Health and the World Health Organization have called for action to address the social determinants of health. This paper considers the extent to which primary health care services in Australia are able to respond to this call. We report on interview data from an empirical study of primary health care centres in Adelaide and Alice Springs, Australia. Methods Sixty-eight interviews were held with staff and managers at six case study primary health care services, regional health executives, and departmental funders to explore how their work responded to the social determinants of health and the dilemmas in doing so. The six case study sites included an Aboriginal Community Controlled Organisation, a sexual health non-government organisation, and four services funded and managed by the South Australian government. Results While respondents varied in the extent to which they exhibited an understanding of social determinants most were reflexive about the constraints on their ability to take action. Services’ responses to social determinants included delivering services in a way that takes account of the limitations individuals face from their life circumstances, and physical spaces in the primary health care services being designed to do more than simply deliver services to individuals. The services also undertake advocacy for policies that create healthier communities but note barriers to them doing this work. Our findings suggest that primary health care workers are required to transverse “dilemmatic space” in their work. Conclusions The absence of systematic supportive policy, frameworks and structure means that it is hard for PHC services to act on the Commission on the Social Determinants of Health’s recommendations. Our study does, however, provide evidence of the potential for PHC services to be more responsive to social determinants given more support and by building alliances with communities and social movements. Further research on the value of community control of PHC services and the types of policy, resource and managerial environments that support action on social determinants is warranted by this study’s findings.

Primary cerebral lymphoma: clinical and aeromedical considerations.
Storms, Patrick R
2007-04-01
Cancer, and the complications of cancer therapy, can present significant obstacles to the airman wishing to return to flying status. If found to be free of recurrent lymphoma and to be neurologically intact after completion of therapy, applicants can be considered for a time-limited medical certificate, provided that they are otherwise qualified. Long-term follow up of patients must include not only disease-free survival time, but also serial neuropsychometric evaluation and quality-of-life assessments. This case illustrates the aeromedical considerations and certification issues for a patient presenting with performance issues progressing to discreet neurological findings, culminating in the diagnosis and treatment of primary central nervous system (CNS) lymphoma.

Objective To explore the experiences of primary care dentists following training to enhance endodontic skills and their views on the implications for the NHS.Design Qualitative study using anonymised free text questionnaires.Setting Primary care general dental services within the National Health Service (NHS) in London, United Kingdom.Subjects and methods Eight primary care dentists who completed this training were asked about factors affecting participant experience of the course, perceived impact on themselves, their organisation, their patients and barriers/facilitators to providing endodontic treatment in NHS primary care. Data were transferred verbatim to a spreadsheet and thematically analysed.Intervention 24-month part-time educational and service initiative to provide endodontics within the NHS, using a combination of training in simulation lab and treatment of patients in primary care.Results Positive impacts were identified at individual (gains in knowledge, skills, confidence, personal development), patient (more teeth saved, quality of care improved) and system levels (access, value for money). Suggested developments for future courses included more case discussions, teaching of practical skills earlier in the course and refinement of the triaging processes. Barriers to using the acquired skills in providing endodontic treatment in primary care within the NHS were perceived to be resources (remuneration, time, skills) and accountability. Facilitators included appropriately remunerated contracts, necessary equipment and time.Conclusion This novel pilot training programme in endodontics combining general practice experience with education/training, hands-on experience and a portfolio was perceived by participants as beneficial for extending skills and service innovation in primary dental care. The findings provide insight into primary dental care practitioners' experience with education/training and have implications for future educational initiatives in support of systems innovation within the NHS.

Primary biliary cirrhosis is associated with other autoimmune diseases including Sjögren's syndrome, and scleroderma. Esophageal dysmotility is well known in scleroderma, and Sjögren's syndrome. The aim of this study is to investigate whether any esophageal motor dysfunction exists in patients with primary biliary cirrhosis. The study was performed in 37 patients (36 women, mean age: 56.29 ± 10.01 years) who met diagnostic criteria for primary biliary cirrhosis. Thirty-seven functional dyspepsia patients, were also included as a control group. Patients entering the study were asked to complete a symptom questionnaire. Distal esophageal contraction amplitude, and lower esophageal sphincter resting pressure were assessed. Manometric findings in primary biliary cirrhosis patients vs. controls were as follows: Median lower esophageal sphincter resting pressure (mmHg): (24 vs 20, p=0.033); median esophageal contraction amplitude (mmHg): (71 vs 56, p=0.050); mean lower esophageal sphincter relaxation duration (sc, x ± SD): (6.10 ± 1.18 vs 8.29 ± 1.92, p<0.001); and median lower esophageal sphincter relaxation (%) (96 vs 98, p=0.019); respectively. No significant differences were evident in median peak velocity (sc) (3.20 vs 3.02, p=0.778) between patients with primary biliary cirrhosis and the functional dyspepsia patients. Esophageal dysmotility was found in 17 (45.9%) primary biliary cirrhosis patients (non-specific esophageal motor disorder in ten patients, hypomotility of esophagus in five patients, nutcracker esophagus in one patient and hypertensive lower esophageal sphincter in one patient). Esophageal dysmotility was detected in 45.9% of patients. The study suggests that subclinic esophageal dysmotility is frequent in patients with primary biliary cirrhosis. Crown Copyright © 2014.

Recent studies, including genome-wide association studies, have identified several putative low-penetrance susceptibility loci for melanoma. We sought to determine their generalizability to genetic predisposition for multiple primary melanoma in the international population-based Genes, Environment, and Melanoma (GEM) Study. GEM is a case-control study of 1,206 incident cases of multiple primary melanoma and 2,469 incident first primary melanoma participants as the control group. We investigated the odds of developing multiple primary melanoma for 47 SNPs from 21 distinct genetic regions previously reported to be associated with melanoma. ORs and 95% confidence intervals were determined using logistic regression models adjusted for baseline features (age, sex, age by sex interaction, and study center). We investigated univariable models and built multivariable models to assess independent effects of SNPs. Eleven SNPs in 6 gene neighborhoods (TERT/CLPTM1L, TYRP1, MTAP, TYR, NCOA6, and MX2) and a PARP1 haplotype were associated with multiple primary melanoma. In a multivariable model that included only the most statistically significant findings from univariable modeling and adjusted for pigmentary phenotype, back nevi, and baseline features, we found TERT/CLPTM1L rs401681 (P = 0.004), TYRP1 rs2733832 (P = 0.006), MTAP rs1335510 (P = 0.0005), TYR rs10830253 (P = 0.003), and MX2 rs45430 (P = 0.008) to be significantly associated with multiple primary melanoma, while NCOA6 rs4911442 approached significance (P = 0.06). The GEM Study provides additional evidence for the relevance of these genetic regions to melanoma risk and estimates the magnitude of the observed genetic effect on development of subsequent primary melanoma. ©2015 American Association for Cancer Research.

The contribution of Physician Assistants in primary care: a systematic review
2013-01-01
Background Primary care provision is important in the delivery of health care but many countries face primary care workforce challenges. Increasing demand, enlarged workloads, and current and anticipated physician shortages in many countries have led to the introduction of mid-level professionals, such as Physician Assistants (PAs). Objective: This systematic review aimed to appraise the evidence of the contribution of PAs within primary care, defined for this study as general practice, relevant to the UK or similar systems. Methods Medline, CINAHL, PsycINFO, BNI, SSCI and SCOPUS databases were searched from 1950 to 2010. Eligibility criteria: PAs with a recognised PA qualification, general practice/family medicine included and the findings relevant to it presented separately and an English language journal publication. Two reviewers independently identified relevant publications, assessed quality using Critical Appraisal Skills Programme tools and extracted findings. Findings were classified and synthesised narratively as factors related to structure, process or outcome of care. Results 2167 publications were identified, of which 49 met our inclusion criteria, with 46 from the United States of America (USA). Structure: approximately half of PAs are reported to work in primary care in the USA with good support and a willingness to employ amongst doctors. Process: the majority of PAs’ workload is the management of patients with acute presentations. PAs tend to see younger patients and a different caseload to doctors, and require supervision. Studies of costs provide mixed results. Outcomes: acceptability to patients and potential patients is consistently found to be high, and studies of appropriateness report positively. Overall the evidence was appraised as of weak to moderate quality, with little comparative data presented and little change in research questions over time. Limitations: identification of a broad range of studies examining ‘contribution’ made meta analysis or meta synthesis untenable. Conclusions The research evidence of the contribution of PAs to primary care was mixed and limited. However, the continued growth in employment of PAs in American primary care suggests that this professional group is judged to be of value by increasing numbers of employers. Further specific studies are needed to fill in the gaps in our knowledge about the effectiveness of PAs’ contribution to the international primary care workforce. PMID:23773235

Primary Prevention of Sexual Violence in Aotearoa New Zealand.
Dickson, Sandra; Willis, Gwenda M
2017-03-01
The extensive and sometimes profoundly damaging effects of sexual violence and large numbers of victims necessitate dedicated attention to primary prevention efforts. Few studies have examined the scope of current prevention activities or their fit with empirical research into effective prevention strategies. The current article presents findings from a survey of primary prevention activities in non-Māori and bicultural communities within Aotearoa New Zealand. Forty-four respondents representing 42 agencies responded to a comprehensive survey that canvased types of sexual violence primary prevention activities undertaken, sexual violence primary prevention programs, and barriers and supports to sexual violence prevention work. Consistent with findings from previous international surveys, the focus of primary prevention work in New Zealand was on sexual violence education and increasing awareness. Findings are discussed in the context of the sexual violence prevention literature and what works in prevention more broadly to help identify promising initiatives as well as gaps in current practices. Recommendations for advancing sexual violence primary prevention research are also provided.

Primary bacterial peritonitis in dogs and cats: 24 cases (1990-2006).
Culp, William T N; Zeldis, Tracy E; Reese, Michael S; Drobatz, Kenneth J
2009-04-01
To determine clinical characteristics of primary bacterial peritonitis (infection of the peritoneal cavity with no identifiable intraperitoneal source of infection) and compare characteristics of primary and secondary peritonitis in dogs and cats. Retrospective case series. 24 (primary peritonitis) and 60 (secondary peritonitis) client-owned dogs and cats. Data from medical records of dogs and cats with primary and secondary peritonitis were reviewed for descriptive information regarding primary peritonitis and for comparison between the 2 forms of peritonitis. 15 dogs and 9 cats met inclusion criteria for primary peritonitis, and 49 dogs and 11 cats met inclusion criteria for secondary peritonitis. The most common historical findings in dogs and cats with primary and secondary peritonitis were lethargy, vomiting, and anorexia. Dogs with secondary peritonitis more often developed peritoneal exudates than those with primary peritonitis, and dogs with primary peritonitis were more often infected with gram-positive bacteria than those with secondary peritonitis. No difference in outcome was detected between all animals with primary versus secondary peritonitis; however, dogs with secondary peritonitis treated with surgery were more commonly discharged than those with primary peritonitis treated with surgery. Differences in primary and secondary peritonitis related to historical, physical examination, and clinical laboratory findings; bacteriologic findings; peritoneal effusion characteristics; and outcome were detected. However, larger case numbers are needed before alternative recommendations, such as avoidance of surgery, can be made.

Patient-centered variables in primary and team nursing.
Hamera, E; O'Connell, K A
1981-03-01
Patient-centered variables and their relationship to primary and team nursing have rarely been studied. In the present study the investigation focused on the following patient-centered variables: nurturance received, patient involvement, and frequency of nurse-patient contacts. Baseline observational data were collected on 12 adult medical patients experiencing team nursing care. A primary nursing care approach was then implemented on the same nursing unit, and 6 months later 12 patients were observed under this system. Patients were directly observed 24 hours a day for 5 days of hospitalization and audiotaped, using a specimen record method. This method produced transcripts that were coded for nurturance, involvement, and nurse-patient contacts. Results of the study showed that there were no differences between primary and team nursing care groups in the number of contacts, nurturance, or patient involvement with all nursing personnel or with professional nurses. However, when the primary group was adjusted to include only those patients for whom primary nursing care was fully implemented, the primary group received more nurturance (p less than .05) and had a tendency to be more active involved than did the team group (p less than .10). These findings indicate that the institution of primary nursing care is related to increased quality of nursing care.

Few morphological differences have been identified so far that distinguish the human brain from the brains of our closest relatives, the apes. Comparative analyses of the spatial organization of cortical neurons, including minicolumns, can aid our understanding of the functionally relevant aspects of microcircuitry. We measured horizontal spacing distance and gray-level ratio in layer III of 4 regions of human and ape cortex in all 6 living hominoid species: frontal pole (Brodmann area [BA] 10), and primary motor (BA 4), primary somatosensory (BA 3), and primary visual cortex (BA 17). Our results identified significant differences between humans and apes in the frontal pole (BA 10). Within the human brain, there were also significant differences between the frontal pole and 2 of the 3 regions studied (BA 3 and BA 17). Differences between BA 10 and BA 4 were present but did not reach significance. These findings in combination with earlier findings on BA 44 and BA 45 suggest that human brain evolution was likely characterized by an increase in the number and width of minicolumns and the space available for interconnectivity between neurons in the frontal lobe, especially the prefrontal cortex.

Corticotropin-releasing hormone, or factor, (CRH or CRF) exerts important biological effects in multiple peripheral tissues via paracrine/autocrine actions. The aim of our study was to assess the effects of endogenous CRH in the biology of mouse and human skin fibroblasts, the primary cell type involved in wound healing. We show expression of CRH and its receptors in primary fibroblasts, and we demonstrate the functionality of fibroblast CRH receptors by induction of cAMP. Fibroblasts genetically deficient in Crh (Crh−/−) had higher proliferation and migration rates and compromised production of IL-6 and TGF-β1 compared to the wildtype (Crh+/+) cells. Human primary cultures of foreskin fibroblasts exposed to the CRF1 antagonist antalarmin recapitulated the findings in the Crh−/− cells, exhibiting altered proliferative and migratory behavior and suppressed production of IL-6. In conclusion, our findings show an important role of fibroblast-expressed CRH in the proliferation, migration, and cytokine production of these cells, processes associated with the skin response to injury. Our data suggest that the immunomodulatory effects of CRH may include an important, albeit not explored yet, role in epidermal tissue remodeling and regeneration and maintenance of tissue homeostasis.

The current financial crisis has seen severe austerity measures imposed on the Spanish health care system, including reduced public spending, copayments, salary reductions, and reduced services for undocumented migrants. However, the impacts have not been well-documented. We present findings from a qualitative study that explores the perceptions of primary health care physicians in Madrid, Spain. This article discusses the effects of austerity measures implemented in the public health care system and their potential impacts on access and utilization of primary health care services. This is the first study, to our knowledge, exploring the health care experiences during the financial crisis of general practitioners in Madrid, Spain. The majority of participating physicians disapproved of austerity measures implemented in Spain. The findings of this study suggest that undocumented migrants should regain access to health care services; copayments should be minimized and removed for patients with low incomes; and health care professionals should receive additional help to avoid burnout. Failure to implement these measures could result in the quality of health care further deteriorating and could potentially have long-term negative consequences on population health. © The Author(s) 2016.

Much research does not address the practical needs of stakeholders responsible for introducing health care delivery interventions into organizations working to achieve better outcomes. In this article, we present an approach to using the Consolidated Framework for Implementation Research (CFIR) to guide systematic research that supports rapid-cycle evaluation of the implementation of health care delivery interventions and produces actionable evaluation findings intended to improve implementation in a timely manner. To present our approach, we describe a formative cross-case qualitative investigation of 21 primary care practices participating in the Comprehensive Primary Care (CPC) initiative, a multi-payer supported primary care practice transformation intervention led by the Centers for Medicare and Medicaid Services. Qualitative data include observational field notes and semi-structured interviews with primary care practice leadership, clinicians, and administrative and medical support staff. We use intervention-specific codes, and CFIR constructs to reduce and organize the data to support cross-case analysis of patterns of barriers and facilitators relating to different CPC components. Using the CFIR to guide data collection, coding, analysis, and reporting of findings supported a systematic, comprehensive, and timely understanding of barriers and facilitators to practice transformation. Our approach to using the CFIR produced actionable findings for improving implementation effectiveness during this initiative and for identifying improvements to implementation strategies for future practice transformation efforts. The CFIR is a useful tool for guiding rapid-cycle evaluation of the implementation of practice transformation initiatives. Using the approach described here, we systematically identified where adjustments and refinements to the intervention could be made in the second year of the 4-year intervention. We think the approach we describe has broad application and encourage others to use the CFIR, along with intervention-specific codes, to guide the efficient and rigorous analysis of rich qualitative data.

Comparing and improving chronic illness primary care in Sweden and the USA.
Øvretveit, John; Ramsay, Patricia; Shortell, Stephen M; Brommels, Mats
2016-06-13
Purpose - The purpose of this paper is to identify opportunities for improving primary care services for people with chronic illnesses by comparing how Sweden and US services use evidence-based practices (EBPs), including digital health technologies (DHTs). Design/methodology/approach - A national primary healthcare center (PHCC) heads surveys in 2012-2013 carried out in both countries in 2006. Findings - There are large variations between the two countries. The largest, regarding effective DHT use in primary care centers, were that few Swedish primary healthcare compared to US heads reported having reminders or prompts at the point of care (38 percent Sweden vs 84 percent USA), despite Sweden's established electronic medical records (EMR). Swedish heads also reported 30 percent fewer centers receiving laboratory results (67 percent Sweden vs 97 percent USA). Regarding following other EBPs, 70 percent of Swedish center heads reported their physicians had easy access to diabetic patient lists compared to 14 percent in the USA. Most Swedish PHCC heads (96 percent) said they offered same day appointment compared to 36 percent in equivalent US practices. Practical implications - There are opportunities for improvement based on significant differences in effective practices between the countries, which demonstrates to primary care leaders that their peers elsewhere potentially provide better care for people with chronic illnesses. Some improvements are under primary care center control and can be made quickly. There is evidence that people with chronic illnesses in these two countries are suffering unnecessarily owing to primary care staff failing to provide proven EBP, which would better meet patient needs. Public finance has been invested in DHT, which are not being used to their full potential. Originality/value - The study shows the gaps between current and potential proven effective EBPs for services to patients with chronic conditions. Findings suggest possible explanations for differences and practical improvements by comparing the two countries. Many enhancements are low cost and the proportionate reduction in suffering and costs they bring is high.

Primary squamous cell carcinomas of the thyroid gland are extremely rare, comprising about 1% of thyroid malignancies. Although squamous cell carcinomas are readily identified as such on aspiration cytology in the majority of cases, the differentiation of primary versus metastatic tumour might not always be easy. Herein, we report three cases of squamous cell carcinomas involving the thyroid gland. Fine needle aspiration cytology (FNAC) was performed in three patients with a thyroid mass using standard guidelines. Smears were stained with Diff-Quik and Papanicolaou stains. Two patients were male and one was female, aged 59, 45 and 35 years, respectively. In all three patients a thyroid mass was present. FNAC smears in all cases showed cytological features of squamous cell carcinoma including keratinization and necrosis. After clinical and cytological correlation, one case appeared to be primary, one case metastatic, and in the third case no additional clinical information or biopsy follow-up was available for further characterization. Because primary squamous cell carcinoma of the thyroid is a rare finding, metastatic squamous cell carcinoma should always be excluded first. Metastatic disease usually presents in the setting of widespread malignancy, therefore a dedicated clinical and radiological investigation is necessary in these cases. In both clinical scenarios the patient's prognosis is poor. © 2010 Blackwell Publishing Ltd.

Diabetes Mellitus is one of the major public health challenges, affecting more than 347 million adults worldwide. The impact of diabetes necessitates assessing the quality of care received by people with diabetes, especially in countries with a significant diabetes burden such as Kuwait. This paper aimed at piloting an approach for measuring Type II diabetes care performance through the use of a diabetes quality indicator set (DQIS) in primary health care. The DQIS for Kuwait was adapted from that developed by the National Diabetes Quality Improvement Alliance and the International Diabetes Federation. Five key care domains/measures were employed: (1) Blood glucose level measurement, (2) Cholesterol level measurement, (3) Blood pressure measurement, (4) Kidney function testing and (5) Smoking status check. The sample included the four major primary health care centers with the highest case load in Kuwait City, 4,241 patients in 2012 and 3,211 in 2010. Findings revealed the applicability and utility of employing performance indicators for diabetes care in Kuwait. Furthermore, findings revealed that many of the primary health care centers have achieved noteworthy improvement in diabetes care between 2010 and 2012, with the exception of smoking status check. The DQIS can help policymakers identify performance gaps and investigate key system roadblocks related to diabetes care in Kuwait.

To report a clinical, histopathological and immunohistochemical findings in a case of primary extranodal marginal zone lymphoma of the uvea associated with massive diffuse extraocular episcleral extension and focal infiltration of the optic nerve and meninges, clinically presented as longstanding uveitis masquerade syndrome. Interventional case reports with histopathological correlation. We describe a 80-year-old male patient with a 3-year history of chronic recurrent hypertensive (pan) uveitis associated with ocular pain, unresponsive to topical and systemic anti-inflammatory, immunosuppressive, antibiotic/antiviral and antiglaucomatous therapy. Because the eye was not salvageable with conservative treatment, enucleation of blind and painful eye was performed. Findings from histopathological and immunohistochemistry examination of the enucleated eye showed an extranodal marginal zone lymphoma of the uveal tract with massive epibulbar extension and optic nerve and meningeal penetration. During almost 3 years of clinical course and 6 months after the enucleation, there were no systemic manifestations of lymphoma, and patient has not required subsequent treatment. Primary lymphoproliferative lesions of the uvea, comprising the iris, ciliary body and choroid are very rare, associated with epibulbar extension extremely and with optic nerve and menigeal penetration exceptionally. Despite its rarity, primary lymphoma of the uvea should be included in the differential diagnosis particularly in older patients with longstanding recurrent uveitis.

Health disparities persist among morbidity and mortality rates in the United States. Contributing significantly to these disparities are the ability to pay for health care (largely, access to health insurance) and access to, and capacity of, the primary care health workforce. This article examines key determinants of health (DOH) including demographics, public and regulatory policies, health workforce capacity, and primary health outcomes of four states of the United States. The context of this study is the potential association among health care disparities and myriad DOH, among them, the restrictive nurse practitioner (NP) scope of practice (SOP) regulatory environment, which are documented to influence access to care and health outcomes. This descriptive study explores current NP SOP regulations, access to primary care, and health outcomes of key chronic disease indicators-diabetes, hypertension, and obesity in Alabama, Colorado, Mississippi, and Utah. These states represent both the greatest disparity in chronic disease health outcomes (obesity, diabetes, and hypertension) and the greatest difference in modernization of their NP SOP laws. The Affordable Care Act has greatly expanded access to health care. However, it is estimated that 23 million Americans, 7% of its total population, will remain uninsured by 2019. Restrictive and inconsistent NP SOP policies may continue to contribute to health workforce capacity and population health disparities across the country, with particular concern for primary care indicators. The study findings bring into question whether states with more restrictive NP SOP regulations impact access to primary care, which may in turn influence population health outcomes. These findings suggest the need for further research. NPs are essential for meeting the increasing demands of primary care in the United States, and quality-of-care indicator research supports their use. Copyright © 2016 Elsevier Inc.

Opportunities for social workers in the patient centered medical home.
Hawk, Mary; Ricci, Edmund; Huber, George; Myers, Marcella
2015-01-01
The Patient Centered Medical Home (PCMH) has been hailed as one method of improving chronic care outcomes in the United States. A number of studies have underscored the importance of the social work role within the PCMH, yet little existing research explores the social worker as a driver of improved patient care. The Pennsylvania Chronic Care Initiative was created with a primary goal of increasing the number of practices that were recognized as PCMH by the National Committee for Quality Assurance. This article describes findings from in-depth qualitative interviews with representatives from seven primary care practices, in which the authors examined barriers and facilitators to implementation of the initiative. Barriers to implementation included small practice size, payer-driven care, not having a strong physician champion, variability within patient populations, and high implementation costs. Facilitators included having a social worker coordinate behavioral health services, clinical nurse case managers, preexisting models of outcomes-driven care, and being part of an integrated health delivery and financing system. Recommendations strengthening the role of medical social workers in primary care practices are discussed.

Medication safety programs in primary care: a scoping review.
Khalil, Hanan; Shahid, Monica; Roughead, Libby
2017-10-01
Medication safety plays an essential role in all healthcare organizations; improving this area is paramount to quality and safety of any wider healthcare program. While several medication safety programs in the hospital setting have been described and the associated impact on patient safety evaluated, no systematic reviews have described the impact of medication safety programs in the primary care setting. A preliminary search of the literature demonstrated that no systematic reviews, meta-analysis or scoping reviews have reported on medication safety programs in primary care; instead they have focused on specific interventions such as medication reconciliation or computerized physician order entry. This scoping review sought to map the current medication safety programs used in primary care. The current scoping review sought to examine the characteristics of medication safety programs in the primary care setting and to map evidence on the outcome measures used to assess the effectiveness of medication safety programs in improving patient safety. The current review considered participants of any age and any condition using care obtained from any primary care services. We considered studies that focussed on the characteristics of medication safety programs and the outcome measures used to measure the effectiveness of these programs on patient safety in the primary care setting. The context of this review was primary care settings, primary healthcare organizations, general practitioner clinics, outpatient clinics and any other clinics that do not classify patients as inpatients. We considered all quantitative studied published in English. A three-step search strategy was utilized in this review. Data were extracted from the included studies to address the review question. The data extracted included type of medication safety program, author, country of origin, aims and purpose of the study, study population, method, comparator, context, main findings and outcome measures. The objectives, inclusion criteria and methods for this scoping review were specified in advance and documented in a protocol that was previously published. This scoping review included nine studies published over an eight-year period that investigated or described the effects of medication safety programs in primary care settings. We classified each of the nine included studies into three main sections according to whether they included an organizational, professional or patient component. The organizational component is aimed at changing the structure of the organization to implement the intervention, the professional component is aimed at the healthcare professionals involved in implementing the interventions, and the patient component is aimed at counseling and education of the patient. All of the included studies had different types of medication safety programs. The programs ranged from complex interventions including pharmacists and teams of healthcare professionals to educational packages for patients and computerized system interventions. The outcome measures described in the included studies were medication error incidence, adverse events and number of drug-related problems. Multi-faceted medication safety programs are likely to vary in characteristics. They include educational training, quality improvement tools, informatics, patient education and feedback provision. The most likely outcome measure for these programs is the incidence of medication errors and reported adverse events or drug-related problems.

Clinical examination findings are used in primary care to give an initial diagnosis to patients with low back pain and related leg symptoms. The purpose of this study was to develop best evidence Clinical Diagnostic Rules (CDR] for the identification of the most common patho-anatomical disorders in the lumbar spine; i.e. intervertebral discs, sacroiliac joints, facet joints, bone, muscles, nerve roots, muscles, peripheral nerve tissue, and central nervous system sensitization. A sensitive electronic search strategy using MEDLINE, EMBASE and CINAHL databases was combined with hand searching and citation tracking to identify eligible studies. Criteria for inclusion were: persons with low back pain with or without related leg symptoms, history or physical examination findings suitable for use in primary care, comparison with acceptable reference standards, and statistical reporting permitting calculation of diagnostic value. Quality assessments were made independently by two reviewers using the Quality Assessment of Diagnostic Accuracy Studies tool. Clinical examination findings that were investigated by at least two studies were included and results that met our predefined threshold of positive likelihood ratio ≥ 2 or negative likelihood ratio ≤ 0.5 were considered for the CDR. Sixty-four studies satisfied our eligible criteria. We were able to construct promising CDRs for symptomatic intervertebral disc, sacroiliac joint, spondylolisthesis, disc herniation with nerve root involvement, and spinal stenosis. Single clinical test appear not to be as useful as clusters of tests that are more closely in line with clinical decision making. This is the first comprehensive systematic review of diagnostic accuracy studies that evaluate clinical examination findings for their ability to identify the most common patho-anatomical disorders in the lumbar spine. In some diagnostic categories we have sufficient evidence to recommend a CDR. In others, we have only preliminary evidence that needs testing in future studies. Most findings were tested in secondary or tertiary care. Thus, the accuracy of the findings in a primary care setting has yet to be confirmed.

Building effective service linkages in primary mental health care: a narrative review part 2
2011-01-01
Background Primary care services have not generally been effective in meeting mental health care needs. There is evidence that collaboration between primary care and specialist mental health services can improve clinical and organisational outcomes. It is not clear however what factors enable or hinder effective collaboration. The objective of this study was to examine the factors that enable effective collaboration between specialist mental health services and primary mental health care. Methods A narrative and thematic review of English language papers published between 1998 and 2009. An expert reference group helped formulate strategies for policy makers. Studies of descriptive and qualitative design from Australia, New Zealand, UK, Europe, USA and Canada were included. Data were extracted on factors reported as enablers or barriers to development of service linkages. These were tabulated by theme at clinical and organisational levels and the inter-relationship between themes was explored. Results A thematic analysis of 30 papers found the most frequently cited group of factors was "partnership formation", specifically role clarity between health care workers. Other factor groups supporting clinical partnership formation were staff support, clinician attributes, clinic physical features and evaluation and feedback. At the organisational level a supportive institutional environment of leadership and change management was important. The expert reference group then proposed strategies for collaboration that would be seen as important, acceptable and feasible. Because of the variability of study types we did not exclude on quality and findings are weighted by the number of studies. Variability in local service contexts limits the generalisation of findings. Conclusion The findings provide a framework for health planners to develop effective service linkages in primary mental health care. Our expert reference group proposed five areas of strategy for policy makers that address organisational level support, joint clinical problem solving, local joint care guidelines, staff training and supervision and feedback.

BMI1 Is Expressed in Canine Osteosarcoma and Contributes to Cell Growth and Chemotherapy Resistance
Gandour-Edwards, Regina; Withers, Sita S.; Holt, Roseline; Rebhun, Robert B.
2015-01-01
BMI1, a stem cell factor and member of the polycomb group of genes, has been shown to contribute to growth and chemoresistance of several human malignancies including primary osteosarcoma (OSA). Naturally occurring OSA in the dog represents a large animal model of human OSA, however the potential role of BMI1 in canine primary and metastatic OSA has not been examined. Immunohistochemical staining of canine primary and metastatic OSA tumors revealed strong nuclear expression of BMI1. An identical staining pattern was found in both primary and metastatic human OSA tissues. Canine OSA cell lines (Abrams, Moresco, and D17) expressed high levels of BMI1 compared with canine osteoblasts and knockdown or inhibition of BMI1 by siRNA or by small molecule BMI1-inhibitor PTC-209 demonstrated a role for BMI1 in canine OSA cell growth and resistance to carboplatin and doxorubicin chemotherapy. These findings suggest that inhibition of BMI1 in primary or metastatic OSA may improve response to chemotherapy and that the dog may serve as a large animal model to evaluate such therapy.

Use of optical tweezers to probe epithelial mechanosensation
NASA Astrophysics Data System (ADS)
Resnick, Andrew
2010-01-01
Cellular mechanosensation mechanisms have been implicated in a variety of disease states. Specifically in renal tubules, the primary cilium and associated mechanosensitive ion channels are hypothesized to play a role in water and salt homeostasis, with relevant disease states including polycystic kidney disease and hypertension. Previous experiments investigating ciliary-mediated cellular mechanosensation have used either fluid flow chambers or micropipetting to elicit a biological response. The interpretation of these experiments in terms of the ``ciliary hypothesis'' has been difficult due the spatially distributed nature of the mechanical disturbance-several competing hypotheses regarding possible roles of primary cilium, glycocalyx, microvilli, cell junctions, and actin cytoskeleton exist. I report initial data using optical tweezers to manipulate individual primary cilia in an attempt to elicit a mechanotransduction response-specifically, the release of intracellular calcium. The advantage of using laser tweezers over previous work is that the applied disturbance is highly localized. I find that stimulation of a primary cilium elicits a response, while stimulation of the apical surface membrane does not. These results lend support to the hypothesis that the primary cilium mediates transduction of mechanical strain into a biochemical response in renal epithelia.

Ubuz, Behiye; Yayan, Betül
2010-09-01
The main objective of this study was to investigate primary teachers' subject matter knowledge in the domain of decimals and more elaborately to investigate their performance and difficulties in reading scale, ordering numbers, finding the nearest decimal and doing operations, such as addition and subtraction. The difficulties in these particular areas are analysed and suggestions are made regarding their causes. Further, factors that influence this knowledge were explored. The sample of the study was 63 primary teachers. A decimal concepts test including 18 tasks was administered and the total scores for the 63 primary teachers ranged from 3 to 18 with a mean and median of 12. Fifty per cent of the teachers were above the mean score. The detailed investigation of the responses revealed that the primary teachers faced similar difficulties that students and pre-service teachers faced. Discrepancy on teachers' knowledge revealed important differences based on educational level attained, but not the number of years of teaching experience and experience in teaching decimals. Some suggestions have been made regarding the implications for pre- and in-service teacher training.

Models of clinical reasoning with a focus on general practice: A critical review
YAZDANI, SHAHRAM; HOSSEINZADEH, MOHAMMAD; HOSSEINI, FAKHROLSADAT
2017-01-01
Introduction: Diagnosis lies at the heart of general practice. Every day general practitioners (GPs) visit patients with a wide variety of complaints and concerns, with often minor but sometimes serious symptoms. General practice has many features which differentiate it from specialty care setting, but during the last four decades little attention was paid to clinical reasoning in general practice. Therefore, we aimed to critically review the clinical reasoning models with a focus on the clinical reasoning in general practice or clinical reasoning of general practitioners to find out to what extent the existing models explain the clinical reasoning specially in primary care and also identity the gaps of the model for use in primary care settings. Methods: A systematic search to find models of clinical reasoning were performed. To have more precision, we excluded the studies that focused on neurobiological aspects of reasoning, reasoning in disciplines other than medicine decision making or decision analysis on treatment or management plan. All the articles and documents were first scanned to see whether they include important relevant contents or any models. The selected studies which described a model of clinical reasoning in general practitioners or with a focus on general practice were then reviewed and appraisal or critics of other authors on these models were included. The reviewed documents on the model were synthesized. Results: Six models of clinical reasoning were identified including hypothetic-deductive model, pattern recognition, a dual process diagnostic reasoning model, pathway for clinical reasoning, an integrative model of clinical reasoning, and model of diagnostic reasoning strategies in primary care. Only one model had specifically focused on general practitioners reasoning. Conclusion: A Model of clinical reasoning that included specific features of general practice to better help the general practitioners with the difficulties of clinical reasoning in this setting is needed.

Background Chronic disease management requires input from multiple health professionals, both specialist and primary care providers. This study sought to assess the impact of co-ordinated multidisciplinary care in primary care, represented by the delivery of formal care planning by primary care teams or shared across primary-secondary teams, on outcomes in stroke, relative to usual care. Methods A Systematic review of Medline, EMBASE, CINAHL (all 1990–2006), Cochrane Library (Issue 1 2006), and grey literature from web based searching of web sites listed in the CCOHA Health Technology Assessment List Analysis used narrative analysis of findings of randomised and non-randomised trials, and observational and qualitative studies of patients with completed stroke in the primary care setting where care planning was undertaken by 1) a multi-disciplinary primary care team or 2) through shared care by primary and secondary providers. Results One thousand and forty-five citations were retrieved. Eighteen papers were included for analysis. Most care planning took part in the context of multidisciplinary team care based in hospitals with outreach to community patients. Mortality rates are not impacted by multidisciplinary care planning. Functional outcomes of the studies were inconsistent. It is uncertain whether the active engagement of GPs and other primary care professionals in the multidisciplinary care planning contributed to the outcomes in the studies showing a positive effect. There may be process benefits from multidisciplinary care planning that includes primary care professionals and GPs. Few studies actually described the tasks and roles GPs fulfilled and whether this matched what was presumed to be provided. Conclusion While multidisciplinary care planning may not unequivocally improve the care of patients with completed stroke, there may be process benefits such as improved task allocation between providers. Further study on the impact of active GP involvement in multidisciplinary care planning is warranted. PMID:18681977

Primary care renewal: regional faculty development and organizational change.
Quirk, Mark E; Haley, Heather-Lyn; Hatem, David; Starr, Susan; Philbin, Mary
2005-03-01
Many reports, including the Future of Family Medicine, have called for change in primary care, but few have defined, implemented, and evaluated mechanisms to address such change. The regional, interdisciplinary Primary Care Renewal Project was designed to address problems in primary care practice and teaching related to practice management, compensation, increasing responsibility for teaching, and faculty development. Twelve northeastern US medical schools assembled a conference attended by teams of key stakeholders representing both clinical and educational missions. Teams developed and implemented an institutional plan to address identified needs. Outcome data was collected during, and for 1 year after, the conference. Findings demonstrate novel ways of improving learning experiences, coordinating and centralizing planning efforts, and addressing faculty needs. The magnitude of organizational change ranged from establishing new administrative units with significant institutional authority (eg, restructuring dean's office) to enhancing the strategic planning process and refining mission statements to reflect emphasis on primary care. A well-planned, regional interdisciplinary effort that fosters the development of concrete plans can be associated with significant change in medical education. A central theme emerged--that primary care medicine will survive only if institutions align their educational and clinical missions and foster system-wide change.

The objective of this study was to compare the clinical and radiographic effects of Allium sativum oil and formocresol in nonvital pulpotomy in primary teeth. Twenty children ranging in age from 4 to 8 years were included in the study. In every one of those children, pulpotomy was indicated for the primary molars. Pulpotomy procedure was performed and the radicular pulp tissue of one molar was capped with A. sativum oil in a cotton pellet while the other molar was capped with formocresol. The teeth were evaluated clinically and radiographically before and after 6 months using standard clinical and radiographic criteria. Statistically, these results revealed significant difference between the radiographic findings of nonvital pulpotomy in primary molars with the two medicaments. Statistical analysis was performed using independent t-test and paired t-test at the significance level of α = 0.05. A. sativum oil has potent antibacterial properties that enable it to combat intracanal microbes in the infected pulp of primary molars. Better results were obtained when A. sativum oil was used. A. sativum oil had more powerful effects than formocresol on the infected pulp of primary nonvital molars.

Introduction The purpose of this qualitative study was to understand the feasibility and acceptability of implementing eHealth Familias Unidas, an Internet-based, family-based, preventive intervention for Hispanic adolescents, in primary care. Methods Semistructured individual interviews with clinic personnel and facilitators (i.e., physicians, nurse practitioners, administrators, and mental health workers; n = 9) and one focus group with parents (n = 6) were audiorecorded, transcribed verbatim, and analyzed using a general inductive approach. Results Nine major themes emerged, including recommendations to minimize disruption to clinic flow, improve collaboration and training of clinic personnel and the research team, promote the clinic as a trusted setting for improving children’s behavioral health, and highlight the flexibility and convenience of the eHealth format. Discussion This study provides feasibility and acceptability findings, along with important considerations for researchers and primary care personnel interested in collaborating to implement an eHealth preventive intervention in pediatric primary care.

We aimed to investigate the effects of febuxostat on IR and the expression of high-sensitivity C-reactive protein (hs-CRP) in patients with primary gout. Forty-two cases of primary gout patients without uric acid-lowering therapy were included in this study. After a physical examination, 20 age- and sex-matched patients were included as normal controls. The levels of fasting insulin (INS), fasting blood glucose (FBG), and hs-CRP were determined. IR was assessed using the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). Gout patients had higher levels of UA, INS, HOMA-IR, and hs-CRP than normal controls (P < 0.05). After 4-, 12-, and 24-week febuxostat treatments, UA and hs-CRP concentrations were significantly lower than baseline (P < 0.05). INS and HOM-IR decreased slightly after a 4-week treatment with febuxostat but declined significantly after 12 and 24 weeks of treatment. Importantly, hs-CRP values positively correlated with those of HOMA-IR (r = 0.353, P = 0.018) and INS (r = 0.426, P = 0.034). Our findings confirm that IR exists in gout patients and implicate that febuxostat can effectively control the level of serum UA and increase insulin sensitivity in primary gout patients.

Objective Studies of patient safety in health care have traditionally focused on hospital medicine. However, recent years have seen more research located in primary care settings which have different features compared to secondary care. This study set out to synthesize published qualitative research concerning patient safety in primary care in order to build a conceptual model. Method Meta-ethnography, an interpretive synthesis method whereby third order interpretations are produced that best describe the groups of findings contained in the reports of primary studies. Results Forty-eight studies were included as 5 discrete subsets where the findings were translated into one another: patients’ perspectives of safety, staff perspectives of safety, medication safety, systems or organisational issues and the primary/secondary care interface. The studies were focused predominantly on issues seen to either improve or compromise patient safety. These issues related to the characteristics or behaviour of patients, staff or clinical systems and interactions between staff, patients and staff, or people and systems. Electronic health records, protocols and guidelines could be seen to both degrade and improve patient safety in different circumstances. A conceptual reading of the studies pointed to patient safety as a subjective feeling or judgement grounded in moral views and with potentially hidden psychological consequences affecting care processes and relationships. The main threats to safety appeared to derive from ‘grand’ systems issues, for example involving service accessibility, resources or working hours which may not be amenable to effective intervention by individual practices or health workers, especially in the context of a public health system. Conclusion Overall, the findings underline the human elements in patient safety primary health care. The key to patient safety lies in effective face-to-face communication between patients and health care staff or between the different staff involved in the care of an individual patient. Electronic systems can compromise safety when they override the opportunities for face-to-face communication. The circumstances under which guidelines or protocols are seen to either compromise or improve patient safety needs further investigation. PMID:26244494

Thakur, Shruti; Jhobta, Anupam; Kumar, Suresh; Thakur, Charu Smita
2014-01-01
Craniosynostosis means premature closure of calvarial sutures. It may be primary or secondary. The patient presents with unexplained neuropsychological impairment and radiological imaging clinches the diagnosis. We present a case of 31-year-old female having primary isolated craniosynostosis who survived into adulthood without any surgical intervention. The imaging findings of such a case are rarely described in the literature.

We analyzed the utility of repeated sestambi scans in patients with primary hyperparathyroidism and its effects on operative referral. We carried out a retrospective review of patients with primary hyperparathyroidism who underwent repeated sestambi scans exclusively within our health system between 1996-2015. Patient demographic, presentation, laboratory, imaging, operative, and pathologic data were reviewed. Univariate analysis with JMP Pro v12 was used to identify factors associated with conversion from an initial negative to a subsequent positive scan. After exclusion criteria (including reoperations), we identified 49 patients in whom 59% (n = 29) of subsequent scans remained negative and 41% (n = 20) converted to positive. Factors associated with an initial negative to a subsequent positive scan included classic presentation and second scans with iodine subtraction (P = .04). Nonsurgeons were less likely to order an iodine-subtraction scan (P < .05). Fewer patients with negative imaging were referred to surgery (33% vs 100%, P = .005), and median time to operation after the first negative scan was 25 months (range 1.4-119). Surgeon-performed ultrasonography had greater sensitivity and positive predictive value than repeated sestamibi scans. Negative sestambi scans decreased and delayed operative referral. Consequently, we identified several process improvement initiatives, including education regarding superior institutional imaging. Combining all findings, we created an algorithm for evaluating patients with primary hyperparathyroidism after initially negative sestamibi scans, which incorporates surgeon-performed ultrasonography.

Breast US as primary imaging modality for diagnosing gynecomastia.
Telegrafo, M; Introna, T; Coi, L; Cornacchia, I; Rella, L; Stabile Ianora, A A; Angelelli, G; Moschetta, M
2016-01-01
To assess the role of breast US in diagnosing and classifying gynecomastia as the primary imaging modality and to compare US findings and classification system with the mammographic ones. 48 patients suspected of having gynecomastia underwent mammography and US. Two radiologists in consensus retrospectively evaluated mammograms and sonograms. Both US and mammographic images were evaluated categorizing gynecomastia into non-mass, nodular and flame shaped patterns. The two category assignations were compared in order to find any difference. The reference standard for both the classification systems was represented by the cytological examination in 18 out of 44 cases (41%) and the six-month US follow-up in the remaining cases. The US examination revealed pseudo-gynecomastia in 4/48 (8%) and true gynecomastia in the remaining 44 (92%). Gynecomastia was bilateral in 25/44 cases (57%) and unilateral in the remaining 19 (43%). The cases of true gynecomastia included non mass shape in 26/44 cases (59%), nodular shape in 12 (27%) and flame shape in 6 (14%). The mammographic examination revealed the same results as compared with US findings. 18/44 (41%) patients affected by nodular or dendritic gynecomastia underwent cytological examination confirming the presence of glandular tissue and the benign nature of the clinical condition. US could be proposed as the primary imaging tool for diagnosing and classifying gynecomastia, avoiding unnecessary Xray examinations or invasive procedures in case of diffuse gynecomastia. In case of nodular or dendritic patterns, biopsy remains mandatory for a definitive diagnosis.

RESOLVE Projects: Lunar Water Resource Demonstration and Regolith Volatile Characterization
NASA Technical Reports Server (NTRS)
2008-01-01
To sustain affordable human and robotic space exploration, the ability to live off the land at the exploration site will be essential. NASA calls this ability in situ resource utilization (ISRU) and is focusing on finding ways to sustain missions first on the Moon and then on Mars. The ISRU project aims to develop capabilities to technology readiness level 6 for the Robotic Lunar Exploration Program and early human missions returning to the Moon. NASA is concentrating on three primary areas of ISRU: (1) excavating, handling, and moving lunar regolith, (2) extracting oxygen from lunar regolith, and (3) finding, characterizing, extracting, separating, and storing volatile lunar resources, especially in the permanently shadowed polar craters. To meet the challenges related to technology development for these three primary focus areas, the Regolith and Environment Science and Oxygen and Lunar Volatile Extraction (RESOLVE) project was initiated in February 2005, through funding by the Exploration Systems Mission Directorate. RESOLVE's objectives are to develop requirements and conceptual designs and to perform breadboard concept verification testing of each experiment module. The final goal is to deliver a flight prototype unit that has been tested in a relevant lunar polar environment. Here we report progress toward the third primary area creating ways to find, characterize, extract, separate, and store volatile lunar resources. The tasks include studying thermal, chemical, and electrical ways to collect such volatile resources as hydrogen, water, nitrogen, methane, and ammonia. We approached this effort through two subtasks: lunar water resource demonstration (LWRD) and regolith volatile characterization (RVC).

After more than a decade of the AIDS epidemic in Thailand, the number of children whose parents are living with HIV or have died from AIDS is increasing significantly and it has been reported that these children are often discriminated against by their peers. In order to better understand the current situation and to explore possible strategies to support HIV-affected children, this study examined children's attitudes towards HIV and AIDS using questionnaires and focus group discussions with children in Grades three-six in five primary schools in a northern province in Thailand. A total of 513 children (274 boys and 239 girls) answered the questionnaire and five focus groups were organised. The findings showed a strong positive correlation between children's belief that HIV could be transmitted through casual contact and their negative attitudes towards their HIV-affected peers. Most children overestimated the risk of HIV transmission through casual contact and this made their attitudes less tolerant and less supportive. After HIV prevention education (which included information on HIV transmission routes) was given in three of the study schools, the same questionnaire and focus groups were repeated and the findings showed that children's attitudes had become more supportive. These findings suggest that HIV prevention education delivered through primary schools in Thailand can be an effective way to help foster a more supportive and inclusive environment and reduce the stigma and discrimination that decrease educational access and attainment for HIV-affected schoolchildren.

Recent studies have shown an improvement in prostate cancer diagnosis with the use of 3.0-Tesla magnetic resonance imaging. We retrospectively assessed the ability of this imaging technique to predict side-specific extracapsular extension of prostate cancer. From October 2007 to August 2011, prostatectomy was carried out in 396 patients after preoperative 3.0-Tesla magnetic resonance imaging. Among these, 132 (primary sample) and 134 patients (validation sample) underwent 12-core prostate biopsy at the National Cancer Center Hospital of Tokyo, Japan, and at other institutions, respectively. In the primary dataset, univariate and multivariate analyses were carried out to predict side-specific extracapsular extension using variables determined preoperatively, including 3.0-Tesla magnetic resonance imaging findings (T2-weighted and diffusion-weighted imaging). A prediction model was then constructed and applied to the validation study sample. Multivariate analysis identified four significant independent predictors (P < 0.05), including a biopsy Gleason score of ≥8, positive 3.0-Tesla diffusion-weighted magnetic resonance imaging findings, ≥2 positive biopsy cores on each side and a maximum percentage of positive cores ≥31% on each side. The negative predictive value was 93.9% in the combination model with these four predictors, meanwhile the positive predictive value was 33.8%. Good reproducibility of these four significant predictors and the combination model was observed in the validation study sample. The side-specific extracapsular extension prediction by the biopsy Gleason score and factors associated with tumor location, including a positive 3.0-Tesla diffusion-weighted magnetic resonance imaging finding, have a high negative predictive value, but a low positive predictive value. © 2013 The Japanese Urological Association.

Non-specialist healthcare providers, including primary and community healthcare workers, in low- and middle-income countries can effectively treat mental illness. However, scaling-up mental health services within existing health systems has been limited by barriers such as stigma against people with mental illness. Therefore, interventions are needed to address attitudes and behaviors among non-specialists. Aimed at addressing this gap, RE ducing S tigma among H ealthc A re P roviders to Improv E mental health services (RESHAPE) is an intervention in which social contact with mental health service users is added to training for non-specialist healthcare workers integrating mental health services into primary healthcare. This protocol describes a mixed methods pilot and feasibility study in primary care centers in Chitwan, Nepal. The qualitative component will include key informant interviews and focus group discussions. The quantitative component consists of a pilot cluster randomized controlled trial (c-RCT), which will establish parameters for a future effectiveness study of RESHAPE compared to training as usual (TAU). Primary healthcare facilities (the cluster unit, k = 34) will be randomized to TAU or RESHAPE. The direct beneficiaries of the intervention are the primary healthcare workers in the facilities ( n = 150); indirect beneficiaries are their patients ( n = 100). The TAU condition is existing mental health training and supervision for primary healthcare workers delivered through the Programme for Improving Mental healthcarE (PRIME) implementing the mental health Gap Action Programme (mhGAP). The primary objective is to evaluate acceptability and feasibility through qualitative interviews with primary healthcare workers, trainers, and mental health service users. The secondary objective is to collect quantitative information on health worker outcomes including mental health stigma (Social Distance Scale), clinical knowledge (mhGAP), clinical competency (ENhancing Assessment of Common Therapeutic factors, ENACT), and implicit attitudes (Implicit Association Test, IAT), and patient outcomes including stigma-related barriers to care, daily functioning, and symptoms. The pilot and feasibility study will contribute to refining recommendations for implementation of mhGAP and other mental health services in primary healthcare settings in low-resource health systems. The pilot c-RCT findings will inform an effectiveness trial of RESHAPE to advance the evidence-base for optimal approaches to training and supervision for non-specialist providers.

A narrative systematic review of factors affecting diabetes prevention in primary care settings
Eyles, Emily
2017-01-01
Background Type 2 diabetes is impacting millions of people globally; however, many future cases can be prevented through lifestyle changes and interventions. Primary care is an important setting for diabetes prevention, for at-risk populations, because it is a patient’s primary point of contact with the health care system and professionals can provide lifestyle counselling and support, as well as monitoring health outcomes. These are all essential elements for diabetes prevention for at-risk adults. Aim To understand the factors related to the delivery and uptake of type 2 diabetes prevention interventions within primary care in higher income countries. Methods For this narrative systematic review, we combined qualitative and quantitative studies of diabetes prevention within a primary care setting for patients at-risk of developing the condition. We used an iterative approach for evidence collection, which included using several databases (MEDLINE, Embase, Pysch info, BNI, SSCI, CINAHL, ASSIA), where we combined diabetes terms with primary care terms. Narrative and thematic synthesis were utilised to identify the prominent themes emerging from the data. Results A database of 6646 records was screened by the research team, and 18 papers were included. Three major themes were identified in this review. The first theme of context and setting of diabetes progression includes the risk and progression of diabetes, primary care as a setting, and where the responsibility for change is thought to lie. This review also found mixed views on the value of preventative services within primary care. The second theme focused on the various patient factors associated with diabetes prevention such as a patient’s motivation to modify their current lifestyle, perceptions and knowledge (or lack thereof) of the impacts of diabetes, lack of follow-up in healthcare settings, and trust in healthcare professionals. The third theme was centred on professional factors impacting on diabetes prevention which included workload, time constraints, resources, self-efficacy and knowledge as well as professionals’ perception of patient motivations towards change. Conclusion This review explored the factors influencing diabetes prevention in primary care, and identified the context of prevention, as well as patient and professional factors related to preventative services being offered in primary care. This systematic review complements previous reviews of real-world settings by exploring the significant factors in prevention, and the findings are relevant to academics, policymakers, patients and practitioners interested in understanding the factors associated with the delivery and uptake of diabetes prevention interventions.

Clinical features presented by a patient with primary macroglobulinemia over a four-year period included cachexia, weight loss, bleeding tendency, anemia, lymphadenopathy, hepatosplenomegaly and recurrent pulmonary bacterial infections. Immunoelectrophoresis demonstrated the presence of a β2 macroglobulin which, on ultracentrifugation, was found to have a sedimentation constant of 14.9 S20, w; this macroglobulin constituted over 40% of the total serum protein. Postmortem findings included the typical “naked” lymphocyte infiltration of the reticuloendothelial system, with septic embolization from a terminal Gram-negative bacteremia, associated with a mesenteric vascular occlusion. A feature of particular interest was the antemortem appearance of gas in the portal venous system, shown on two abdominal scout radiographs taken one and two hours before death. The diagnostic significance of this rare radiologic sign is discussed. ImagesFig. 1Fig. 2Fig. 3Fig. 4Fig. 5Fig. 6Fig. 7Fig. 8Fig. 9Fig. 10Fig. 11Fig. 12Fig. 13Fig. 14Fig. 15 PMID:14226112

Lymphoproliferative lung disorders: a radiologic-pathologic overview. Part II: Neoplastic disorders.
Restrepo, Carlos S; Carrillo, Jorge; Rosado de Christenson, Melissa; Ojeda Leon, Paulina; Lucia Rivera, Aura; Koss, Micheal N
2013-12-01
Lymphoproliferative pulmonary neoplasms can occur as primary pulmonary lymphomas or because of secondary pulmonary involvement. Neoplastic disorders may be difficult to differentiate from reactive pulmonary lymphoproliferative disorders, and immunohistochemical evaluation is often required to differentiate the 2 types of lesions. Neoplastic lymphoproliferative disorders are monoclonal lesions. Most affected patients present with systemic complaints, and imaging findings typically include nodules, masses, and lymphadenopathy. Primary pulmonary lymphomas are rare and account for less than 4% of the lymphomas that arise in extranodal sites. Secondary pulmonary lymphomas can affect the lung via hematogenous dissemination or by secondary involvement from tumor in adjacent or contiguous sites. Neoplastic lymphoproliferative lesions also include leukemia and plasma cell neoplasms. Posttransplantation lymphoproliferative disorders constitute a special type of lymphoid proliferation occurring in the setting of the chronic immunosuppression required for solid organ and bone marrow transplantation.

The prevalence of BRAF, NRAS, and p16CDKN2A mutations during melanoma progression remains inconclusive. We investigated the prevalence and distribution of mutations in these genes in different melanoma tissues. In all, 291 tumor tissues from 132 patients with melanoma were screened. Paired samples of primary melanomas (n = 102) and synchronous or asynchronous metastases from the same patients (n = 165) were included. Tissue samples underwent mutation analysis (automated DNA sequencing). Secondary lesions included lymph nodes (n = 84), and skin (n = 36), visceral (n = 25), and brain (n = 44) sites. BRAF/NRAS mutations were identified in 58% of primary melanomas (43% BRAF; 15% NRAS); 62% in lymph nodes, 61% subcutaneous, 56% visceral, and 70% in brain sites. Mutations were observed in 63% of metastases (48% BRAF; 15% NRAS), a nonsignificant increase in mutation frequency after progression from primary melanoma. Of the paired samples, lymph nodes (93% consistency) and visceral metastases (96% consistency) presented a highly similar distribution of BRAF/NRAS mutations versus primary melanomas, with a significantly less consistent pattern in brain (80%) and skin metastases (75%). This suggests that independent subclones are generated in some patients. p16CDKN2A mutations were identified in 7% and 14% of primary melanomas and metastases, with a low consistency (31%) between secondary and primary tumor samples. In the era of targeted therapies, assessment of the spectrum and distribution of alterations in molecular targets among patients with melanoma is needed. Our findings about the prevalence of BRAF/NRAS/p16CDKN2A mutations in paired tumor lesions from patients with melanoma may be useful in the management of this disease.

Homeless youth are a growing, vulnerable population with specific primary health care (PHC) requirements. There are no systematic reviews of evidence to guide the delivery of PHC interventions to best address the needs of homeless youth in Australia. We present a narrative synthesis of peer reviewed research designed to determine: (1) the PHC services homeless youth access; (2) experiences of services, reported outcomes and barriers to use; and, (3) the PHC service needs of homeless youth. Findings show that homeless youth access a variety of services and delivery approaches. Increased PHC use is associated with youth who recognise they need help. Street-based clinic linked services and therapy and case management alongside improved housing can positively impact upon mental health and substance use outcomes. Barriers to service use include knowledge; provider attitudes, financial constraints and inappropriate environments. Findings support targetted, co-ordinated networks of PHC and housing services with nurses working alongside community workers.

A persistent finding is that assisted reproductive technology (ART) is associated with compromised birth outcomes, including higher risks for prematurity, low birthweight, and congenital malformations, even among singletons. Over the past decade, our research group, the Massachusetts Outcome Study of Assisted Reproductive Technology (MOSART), has evaluated pregnancy and birth outcomes among three groups of women, those women treated with ART, those with indicators of subfertility but without ART treatment, and fertile women. We have also explored the influence of infertility-related diagnoses on outcomes for women and infants. Over the course of our research, we have changed our perspective from an original focus on ART treatment parameters as the primary cause of excess morbidity to one centered instead on the underlying infertility-related diagnoses. This paper summarizes the research findings from our group that support this change in focus for infertility-based research from a primary emphasis on ART treatment to greater attention to the contribution of preexisting pathology underlying the infertility and suggests directions for future analyses.

Acute primary hyperparathyroidism and parathyroid crisis are characterized by life-threatening hypercalcemia, a rare disorder. A 69-year-old female patient presented at our hospital’s neurology clinic with weakness, nausea, vomiting, depression, and hypercalcemia. Treatment of hypercalcemia resulted in no improvement in neurological symptoms, indicating resistance to treatment. Thyroid ultrasonography and parathyroid scintigraphy revealed hypoechoic nodules in the right lobe, pieces of nodules in the left lobe, and high serum calcium and parathyroid hormone levels. After provision of intensive medical treatment including hydration, diuresis, and bisphosphonate infusion resulted in only minimal decrease in the calcium level, urgent surgical treatment was performed. Frozen biopsy of the right intrathyroidal giant parathyroid adenoma in the right lobe confirmed initial diagnosis of primary hyperparathyroidism. Based on the biopsy findings, right parathyroidectomy and right total and left subtotal thyroidectomy were performed. Histopathologic examination revealed a parathyroid adenoma localized inside large thyroid nodules. Review of the findings resulted in diagnosis of intrathyroidal parathyroid adenoma. Symptoms of hypercalcemia improved rapidly during the postoperative period. PMID:25785164

To synthesize new findings from the THRIVE Research Collaborative (The Research Initiative Valuing Eldercare) related to the Green House (GH) model of nursing home care and broadly consider their implications. Interviews and observations conducted in GH and comparison homes, Minimum Data Set (MDS) assessments, Medicare data, and Online Survey, Certification and Reporting data. Critical integration and interpretation of findings based on primary data collected 2011-2014 in 28 GH homes (from 16 organizations), and 15 comparison nursing home units (from 8 organizations); and secondary data derived from 2005 to 2010 for 72 GH homes (from 15 organizations) and 223 comparison homes. Implementation of the GH model is inconsistent, sometimes differing from design. Among residents of GH homes, adoption lowers hospital readmissions, three MDS measures of poor quality, and Part A/hospice Medicare expenditures. Some evidence suggests the model is associated with lower direct care staff turnover. Recommendations relate to assessing fidelity, monitoring quality, capitalizing opportunities to improve care, incorporating evidence-based practices, including primary care providers, supporting high-performance workforce practices, aligning Medicare financial incentives, promoting equity, informing broad culture change, and conducting future research. © Health Research and Educational Trust.

Craniosynostosis means premature closure of calvarial sutures. It may be primary or secondary. The patient presents with unexplained neuropsychological impairment and radiological imaging clinches the diagnosis. We present a case of 31-year-old female having primary isolated craniosynostosis who survived into adulthood without any surgical intervention. The imaging findings of such a case are rarely described in the literature. PMID:24753669

To examine a local primary health care infrastructure and the reality of primary health care from the perspective of residents of a small, urban community in the southern United States. Data derive from 13 semi-structured focus groups, plus three semi-structured interviews, and were analyzed inductively consistent with a grounded theory approach. Structural barriers to the local primary health care infrastructure include transportation, clinic and appointment wait time, and co-payments and health insurance. Hidden barriers consist of knowledge about local health care services, non-physician gatekeepers, and fear of medical care. Community residents have used home remedies and the emergency department at the local academic medical center to manage these structural and hidden barriers. Findings might not generalize to primary health care infrastructures in other communities, respondent perspectives can be biased, and the data are subject to various interpretations and conceptual and thematic frameworks. Nevertheless, the structural and hidden barriers to the local primary health care infrastructure have considerably diminished the autonomy community residents have been able to exercise over their decisions about primary health care, ultimately suggesting that efforts concerned with increasing the access of medically underserved groups to primary health care in local communities should recognize the centrality and significance of power. This study addresses a gap in the sociological literature regarding the impact of specific barriers to primary health care among medically underserved groups.

Divisions of general practice in Australia: how do they measure up in the international context?
Smith, Judith; Sibthorpe, Beverly
2007-01-01
Background Since the late 1980s, there has been evidence of an international trend towards more organised primary care. This has taken a number of forms including the emergence of primary care organisations. Underpinning such developments is an inherent belief in evidence that suggests that well-developed primary care is associated with improved health outcomes and greater cost-effectiveness within health systems. In Australia, primary care organisations have emerged as divisions of general practice. These are professionally-led, regionally-based, and largely government-funded voluntary associations of general practitioners that seek to co-ordinate local primary care services, and improve the quality of care and health outcomes for local communities. Discussion In this paper, we examine and debate the development of divisions in the international context, using six roles of primary care organisations outlined in published research. The six roles that are used as the basis for the critique are the ability of primary care organisations to: improve health outcomes; manage demand and control costs; engage primary care physicians; enable greater integration of health services; develop more accessible services in community and primary care settings; and enable greater scrutiny and assurance of quality of primary care services. Summary We conclude that there has been an evolutionary approach to divisions' development and they now appear embedded as geographically-based planning and development organisations within the Australian primary health care system. The Australian Government has to date been cautious in its approach to intervention in divisions' direction and performance. However, options for the next phase include: making greater use of contracts between government and divisions; introducing and extending proposed national quality targets for divisions, linked with financial or other incentives for performance; government sub-contracting with state-based organisations to act as purchasers of care; pursuing a fund-holding approach within divisions; and developing divisions as a form of health maintenance organisation. The challenge for the Australian Government, should it wish to see divisions' role expand, is to find mechanisms to enable this without compromising the relatively strong GP engagement that increasingly distinguishes divisions of general practice within the international experience of primary care organisations.

External supervision of primary healthcare facilities in low- and middle-income countries often has a managerial main purpose in which the role of support for professional development is unclear. To explore how Rwandan primary healthcare supervisors and providers (supervisees) perceive evaluative and formative functions of external supervision. Qualitative, exploratory study. Focus group discussions: three with supervisors, three with providers, and one mixed (n = 31). Findings were discussed with individual and groups of supervisors and providers. Evaluative activities occupied providers' understanding of supervision, including checking, correcting, marking and performance-based financing. These were presented as sources of motivation, that in self-determination theory indicate introjected regulation. Supervisors preferred to highlight their role in formative supervision, which may mask their own and providers' uncontested accounts that systematic performance evaluations predominated supervisors' work. Providers strongly requested larger focus on formative and supportive functions, voiced as well by most supervisors. Impact of performance evaluation on motivation and professional development is discussed. While external supervisors intended to support providers' professional development, our findings indicate serious problems with this in a context of frequent evaluations and performance marking. Separating the role of supporter and evaluator does not appear as the simple solution. If external supervision is to improve health care services, it is essential that supervisors and health centre managers are competent to support providers in a way that transparently accounts for various performance pressures. This includes delivery of proper formative supervision with useful feedback, maintaining an effective supervisory relationship, as well as ensuring providers are aware of the purpose and content of evaluative and formative supervision functions.

The Chronic Care Model (CCM) is a framework developed to redesign care delivery for individuals living with chronic diseases in primary care. The CCM and its various components have been widely adopted and evaluated, however, little is known about different primary care experiences with its implementation, and the factors that influence its successful uptake. The purpose of this review is to synthesize findings of studies that implemented the CCM in primary care, in order to identify facilitators and barriers encountered during implementation. This study identified English-language, peer-reviewed research articles, describing the CCM in primary care settings. Searches were performed in three data bases: Web of Knowledge, Pubmed and Scopus. Article abstracts and titles were read based on whether they met the following inclusion criteria: 1) studies published after 2003 that described or evaluated the implementation of the CCM; 2) the care setting was primary care; 3) the target population of the study was adults over the age of 18 with chronic conditions. Studies were categorized by reference, study design and methods, participants and setting, study objective, CCM components used, and description of the intervention. The next stage of data abstraction involved qualitative analysis of cited barriers and facilitators using the Consolidating Framework for Research Implementation. This review identified barriers and facilitators of implementation across various primary care settings in 22 studies. The major emerging themes were those related to the inner setting of the organization, the process of implementation and characteristics of the individual healthcare providers. These included: organizational culture, its structural characteristics, networks and communication, implementation climate and readiness, presence of supportive leadership, and provider attitudes and beliefs. These findings highlight the importance of assessing organizational capacity and needs prior to and during the implementation of the CCM, as well as gaining a better understanding of health care providers' and organizational perspective.

Research needs for an improved primary care response to chronic non-communicable diseases in Africa.
Maher, D; Sekajugo, J; Harries, A D; Grosskurth, H
2010-02-01
With non-communicable diseases (NCDs) projected to become leading causes of morbidity and mortality in developing countries, research is needed to improve the primary care response, especially in sub-Saharan Africa. This region has a particularly high double burden of communicable diseases and NCDs and the least resources for an effective response. There is a lack of good quality epidemiological data from diverse settings on chronic NCD burden in sub-Saharan Africa, and the approach to primary care of people with chronic NCDs is currently often unstructured. The main primary care research needs are therefore firstly, epidemiological research to document the burden of chronic NCDs, and secondly, health system research to deliver the structured, programmatic, public health approach that has been proposed for the primary care of people with chronic NCDs. Documentation of the burden and trends of chronic NCDs and associated risk factors in different settings and different population groups is needed to enable health system planning for an improved primary care response. Key research issues in implementing the programmatic framework for an improved primary care response are how to (i) integrate screening and prevention within health delivery; (ii) validate the use of standard diagnostic protocols for NCD case-finding among patients presenting to the local health facilities; (iii) improve the procurement and provision of standardised treatment and (iv) develop and implement a data collection system for standardised monitoring and evaluation of patient outcomes. Important research considerations include the following: selection of research sites and the particular NCDs targeted; research methodology; local research capacity; research collaborations; ethical issues; translating research findings into policy and practice and funding. Meeting the research needs for an improved health system response is crucial to deliver effective, affordable and equitable care for the millions of people with chronic NCDs in developing countries in Africa.

Primary cilia are non-motile sensory cytoplasmic organelles that are involved in cell cycle progression. Ultrastructurally, the primary cilium region is complex, with normal ciliogenesis progressing through five distinct morphological stages in human astrocytes. Defects in early stages of ciliogenesis are key features of astrocytoma/glioblastoma cell lines and provided the impetus for the current study which describes the morphology of primary cilia in molecularly characterized human glioblastoma multiforme (GBM) tumors. Seven surgically resected human GBM tissue samples were molecularly characterized according to IDH1/2 mutation status, EGFR amplification status and MGMT promoter methylation status and were examined for primary cilia expression and structure using indirect immunofluorescence and electron microscopy. We report for the first time that primary cilia are disrupted in the early stages of ciliogenesis in human GBM tumors. We confirm that immature primary cilia and basal bodies/centrioles have aberrant ciliogenesis characteristics including absent paired vesicles, misshaped/swollen vesicular hats, abnormal configuration of distal appendages, and discontinuity of centriole microtubular blades. Additionally, the transition zone plate is able to form in the absence of paired vesicles on the distal end of the basal body and when a cilium progresses beyond the early stages of ciliogenesis, it has electron dense material clumped along the transition zone and a darkening of the microtubules at the proximal end of the cilium. Primary cilia play a role in a variety of human cancers. Previously primary cilia structure was perturbed in cultured cell lines derived from astrocytomas/glioblastomas; however there was always some question as to whether these findings were a cell culture phenomena. In this study we confirm that disruptions in ciliogenesis at early stages do occur in GBM tumors and that these ultrastructural findings bear resemblance to those previously observed in cell cultures. This is the first study to demonstrate that defects in cilia expression and function are a true hallmark of GBM tumors and correlate with their unrestrained growth. A review of the current ultrastructural profiles in the literature provides suggestions as to the best possible candidate protein that underlies defects in the early stages of ciliogenesis within GBM tumors.

Abstract Objective The purpose of this study was to determine psychiatrists' barriers, attitudes, and practices regarding cardiac screening prior to initiating stimulants in children with attention-deficit/hyperactivity disorder. Background Professional and federal oversight organizations recently have debated the evidence regarding sudden cardiac death (SCD) risk with stimulants, and have published guidelines recommending cardiac screening. It is not known how psychiatrists have responded. Methods This study was a cross-sectional survey of 1,600 randomly-selected U.S. members of the American Academy of Child and Adolescent Psychiatry. Analyses included descriptive statistics and logistic regression. Results Response rate was 40%; 96% met eligibility criteria. Barriers to identifying cardiac disorders in general included ability to perform a routine physical examination (74%) and care coordination with primary care providers (35%). Only 27% agreed that SCD risk warranted cardiac assessment. Prior to starting a patient on stimulants, 95% of psychiatrists obtained a routine history. The majority either conducted (9%), or relied on primary care providers to conduct (67%) a physical examination; 26% did not obtain a physical examination. Nineteen percent of psychiatrists ordered an electrocardiogram (ECG), of those, non-mutually exclusive reasons for ordering an ECG included standard practice procedure (62%), clinical findings (27%), medicolegal considerations (25%), and guideline adherence (24%). On multivariate modeling, psychiatrists were less likely to conduct cardiac screening themselves if in private practice (referent: academic medical center), if >50% of their patients had private insurance, or if they believed their ability to perform a physical examination to be a barrier. When modeling cardiac screening performed by any healthcare professional (e.g., psychiatrist, primary care practitioner), screening was less likely if the psychiatrist was practicing in a community mental health center (referent: academic medical center), was male, or if >50% of that psychiatrist's patients had private insurance. Conclusion Findings suggest the tacit interplay between primary care and psychiatry for the assessment and management of medical risks associated with psychotropic medications should be improved, and solutions prioritized.

Background The burden of non-communicable diseases, including type 2 diabetes, is growing in South Africa. This country has a complex mix of over- and under-nutrition, especially in low-income communities, and concerning levels of physical inactivity in children and youth. This paper describes HealthKick, a school-based nutrition and physical activity intervention in primary schools in these settings aimed at reducing diabetes risk factors. Methods/Design This study includes schools within historically disadvantaged, low-income communities from an urban area close to the city of Cape Town and from two rural areas outside of Cape Town, South Africa. The three Educational Districts involved are Metropole North, Cape Winelands and the Overberg. The study has three phases: intervention mapping and formative assessment, intervention development, and outcome and process evaluation. Sixteen schools were purposively selected to participate in the study and randomly allocated as intervention (eight schools) and control (eight schools). The primary aims of HealthKick are to promote healthful eating habits and increase regular participation in health-enhancing physical activity in children, parents and teachers, to prevent overweight, and reduce risk of chronic diseases (particularly type 2 diabetes); as well as to promote the development of an environment within the school and community that facilitates the adoption of healthy lifestyles. The components of HealthKick are: action planning, toolkit (resource guide, a resource box and physical activity resource bin), and an Educators' Manual, which includes a curriculum component. Discussion This study continues to highlight the key role that educators play in implementing a school-based intervention, but that developing capacity within school staff and stakeholders is not a simple or easy task. In spite of the challenges experienced thus far, valuable findings are being produced from this study, especially from Phase 1. Materials developed could be disseminated to other schools in low-income settings both within and outside of South Africa. Owing to the novelty of the HealthKick intervention in low-income South African primary schools, the findings of the evaluation phase have the potential to impact on policy and practice within these settings.

Son, Hee Jung; Rhee, Poong Lyul; Kim, Jae-Jun; Koh, Kwang Choel; Paik, Seong Woon; Rhee, Jong Chul; Koh, Young Hae
1997-01-01
A 40-year-old woman had been diagnosed with Crohns disease in September 1994, but later examinations revealed a primary T-cell lymphoma of the colon. Colonoscopic and histological examination showed ulcerative lesions simulating Crohns disease involving the entire colon and the terminal ileum, and she was first diagnosed as having Crohns disease. Differential therapeutic strategies, including corticosteroid, had improved the symptoms which were dominated by abdominal pain. When she visited our institute in April 1995, she presented with bloody stool twice a day, 7kg weight loss in a period of six months and a slightly painful abdomen. Colonoscopic finding showed geographic ulceration on the entire colon, especially rectum and terminal ileum. The histologic examination of specimens from colonoscopic biopsy showed primary peripheral T-cell lymphoma of the colon. Any dense lymphocyte infiltrates seen in the biopsy specimens obtained from lesions simulating ulcerative colitis or Crohns disease should be assessed to exclude intestinal lymphoma PMID:9439161

Learning organisations: the challenge of finding a safe space in a climate of accountability.
McKee, Anne
2017-03-01
The effects of health policy reforms over a twenty-five year period have changed the NHS as a place in which to work and learn. Some of these changes have had unintentional consequences for learning in the workplace. A recent King's Fund contribution to quality improvement debates included an extensive review of NHS policies encouraging change 'from within' the NHS and renewed calls to develop learning organisations there. I draw upon an action research project designed to develop learning organisations in primary care to locate quality improvement debates amid the realities of practice. The project identified key challenges primary care practices encountered to protect time and space for this form of work based learning, even when they recognised the need for it and wanted to engage in it. Implications for policy makers, primary care practices and health professional educationalists are identified.

Metals and Disease: A Global Primary Health Care Perspective
Mamtani, Ravinder; Stern, Penny; Dawood, Ismail; Cheema, Sohaila
2011-01-01
Metals are an important and essential part of our daily lives. Their ubiquitous presence and use has not been without significant consequences. Both industrial and nonindustrial exposures to metals are characterized by a variety of acute and chronic ailments. Underreporting of illnesses related to occupational and environmental exposures to chemicals including metals is of concern and presents a serious challenge. Many primary care workers rarely consider occupational and environmental exposures to chemicals in their clinical evaluation. Their knowledge and training in the evaluation of health problems related to such exposures is inadequate. This paper presents documented research findings from various studies that have examined the relationship between metal exposures and their adverse health effects both in developing and developed countries. Further, it provides some guidance on essential elements of a basic occupational and environmental evaluation to health care workers in primary care situations. PMID:22007209

A subjective evaluation of high-chroma color with wide color-gamut display
NASA Astrophysics Data System (ADS)
Kishimoto, Junko; Yamaguchi, Masahiro; Ohyama, Nagaaki
2009-01-01
Displays tends to expand its color gamut, such as multi-primary color display, Adobe RGB and so on. Therefore displays got possible to display high chroma colors. However sometimes, we feel unnatural some for the image which only expanded chroma. Appropriate gamut mapping method to expand color gamut is not proposed very much. We are attempting preferred expanded color reproduction on wide color gamut display utilizing high chroma colors effectively. As a first step, we have conducted an experiment to investigate the psychological effect of color schemes including highly saturated colors. We used the six-primary-color projector that we have developed for the presentation of test colors. The six-primary-color projector's gamut volume in CIELAB space is about 1.8 times larger than the normal RGB projector. We conducted a subjective evaluation experiment using the SD (Semantic Differential) technique to find the quantitative psychological effect of high chroma colors.

Cochrane Systematic Reviews of Chinese Herbal Medicines: An Overview
Hu, Jing; Zhang, Junhua; Zhao, Wei; Zhang, Yongling; Zhang, Li; Shang, Hongcai
2011-01-01
Objectives Our study had two objectives: a) to systematically identify all existing systematic reviews of Chinese herbal medicines (CHM) published in Cochrane Library; b) to assess the methodological quality of included reviews. Methodology/Principal Findings We performed a systematic search of the Cochrane Database of Systematic Reviews (CDSR, Issue 5, 2010) to identify all reviews of CHM. A total of fifty-eight reviews were eligible for our study. Twenty-one of the included reviews had at least one Traditional Chinese Medicine (TCM) practitioner as its co-author. 7 reviews didn't include any primary study, the remaining reviews (n = 51) included a median of 9 studies and 936 participants. 50% of reviews were last assessed as up-to-date prior to 2008. The questions addressed by 39 reviews were broad in scope, in which 9 reviews combined studies with different herbal medicines. For OQAQ, the mean of overall quality score (item 10) was 5.05 (95% CI; 4.58-5.52). All reviews assessed the methodological quality of primary studies, 16% of included primary studies used adequate sequence generation and 7% used adequate allocation concealment. Of the 51 nonempty reviews, 23 reviews were reported as being inconclusive, while 27 concluded that there might be benefit of CHM, which was limited by the poor quality or inadequate quantity of included studies. 58 reviews reported searching a median of seven electronic databases, while 10 reviews did not search any Chinese database. Conclusions Now CDSR has included large numbers of CHM reviews, our study identified some areas which could be improved, such as almost half of included reviews did not have the participation of TCM practitioners and were not up-to-date according to Cochrane criteria, some reviews pooled the results of different herbal medicines and ignored the searching of Chinese databases.

A metastatic glomus jugulare tumor. A temporal bone report
DOE Office of Scientific and Technical Information (OSTI.GOV)
El Fiky, F.M.; Paparella, M.M.
The clinicopathologic findings in the temporal bone of a patient with a highly malignant metastasizing glomus jugulare tumor are reported. The patient exhibited all the symptoms of primary malignant tumors of the ear, including facial paralysis, otorrhea, pain, hearing loss, tinnitus, dizziness, and vertigo. He was treated with cobalt irradiation followed by radium implant in the ear canal for a residual tumor; then a left-sided radical mastoidectomy was performed.

Polypoid lesions of the gallbladder: disease spectrum with pathologic correlation.
Mellnick, Vincent M; Menias, Christine O; Sandrasegaran, Kumar; Hara, Amy K; Kielar, Ania Z; Brunt, Elizabeth M; Doyle, Maria B Majella; Dahiya, Nirvikar; Elsayes, Khaled M

Gallbladder polyps are seen on as many as 7% of gallbladder ultrasonographic images. The differential diagnosis for a polypoid gallbladder mass is wide and includes pseudotumors, as well as benign and malignant tumors. Tumefactive sludge may be mistaken for a gallbladder polyp. Pseudotumors include cholesterol polyps, adenomyomatosis, and inflammatory polyps, and they occur in that order of frequency. The most common benign and malignant tumors are adenomas and primary adenocarcinoma, respectively. Polyp size, shape, and other ancillary imaging findings, such as a wide base, wall thickening, and coexistent gallstones, are pertinent items to report when gallbladder polyps are discovered. These findings, as well as patient age and risk factors for gallbladder cancer, guide clinical decision making. Symptomatic polyps without other cause for symptoms, an age over 50 years, and the presence of gallstones are generally considered indications for cholecystectomy. Incidentally noted pedunculated polyps smaller than 5 mm generally do not require follow-up. Polyps that are 6-10 mm require follow-up, although neither the frequency nor the length of follow-up has been established. Polyps that are larger than 10 mm are typically excised, although lower size thresholds for cholecystectomy may be considered for patients with increased risk for gallbladder carcinoma, such as patients with primary sclerosing cholangitis.

Background: Chemical toxicity testing is being transformed by advances in biology and computer modeling, concerns over animal use and the thousands of environmental chemicals lacking toxicity data. EPA's ToxCast program aims to address these concerns by screening and prioritizing chemicals for potential human toxicity using in vitro assays and in silico approaches. Objectives: This project aims to evaluate the use of in vitro assays for understanding the types of molecular and pathway perturbations caused by environmental chemicals and to build initial prioritization models of in vivo toxicity. Methods: We tested 309 mostly pesticide active chemicals in 467 assays across 9 technologies, including high-throughput cell-free assays and cell-based assays in multiple human primary cells and cell lines, plus rat primary hepatocytes. Both individual and composite scores for effects on genes and pathways were analyzed. Results: Chemicals display a broad spectrum of activity at the molecular and pathway levels. Many expected interactions are seen, including endocrine and xenobiotic metabolism enzyme activity. Chemicals range in promiscuity across pathways, from no activity to affecting dozens of pathways. We find a statistically significant inverse association between the number of pathways perturbed by a chemical at low in vitro concentrations and the lowest in vivo dose at which a chemical causes toxicity. We also find associations between a small set in vitro ass

Background. Psychosocial stressors in the workplace are a cause of anxiety and depressive illnesses, suicide and family disruption. Methods. The present review synthesizes the evidence from existing systematic reviews published between 1990 and July 2011. We assessed the effectiveness of individual, organisational and mixed interventions on two outcomes: mental health and absenteeism. Results. In total, 23 systematic reviews included 499 primary studies; there were 11 meta-analyses and 12 narrative reviews. Meta-analytic studies found a greater effect size of individual interventions on individual outcomes. Organisational interventions showed mixed evidence of benefit. Organisational programmes for physical activity showed a reduction in absenteeism. The findings from the meta-analytic reviews were consistent with the findings from the narrative reviews. Specifically, cognitive-behavioural programmes produced larger effects at the individual level compared with other interventions. Some interventions appeared to lead to deterioration in mental health and absenteeism outcomes.Gaps in the literature include studies of organisational outcomes like absenteeism, the influence of specific occupations and size of organisations, and studies of the comparative effectiveness of primary, secondary and tertiary prevention. Conclusions. Individual interventions (like CBT) improve individuals' mental health. Physical activity as an organisational intervention reduces absenteeism. Research needs to target gaps in the evidence. PMID:22496705

Clonal architecture in myeloproliferative neoplasms (MPNs) is poorly understood. Here we report genomic analyses of a patient with primary myelofibrosis (PMF) transformed to secondary acute myeloid leukemia (sAML). Whole genome sequencing (WGS) was performed on PMF and sAML diagnosis samples, with skin included as a germline surrogate. Deep sequencing validation was performed on the WGS samples and an additional sample obtained during sAML remission/relapsed PMF. Clustering analysis of 649 validated somatic single-nucleotide variants revealed four distinct clonal groups, each including putative driver mutations. The first group (including JAK2 and U2AF1), representing the founding clone, included mutations with high frequency at all three disease stages. The second clonal group (including MYB) was present only in PMF, suggesting the presence of a clone that was dispensable for transformation. The third group (including ASXL1) contained mutations with low frequency in PMF and high frequency in subsequent samples, indicating evolution of the dominant clone with disease progression. The fourth clonal group (including IDH1 and RUNX1) was acquired at sAML transformation and was predominantly absent at sAML remission/relapsed PMF. Taken together, these findings illustrate the complex clonal dynamics associated with disease evolution in MPNs and sAML.

A Cascade of Wnt, Eda, and Shh Signaling Is Essential for Touch Dome Merkel Cell Development.
Xiao, Ying; Thoresen, Daniel T; Miao, Lingling; Williams, Jonathan S; Wang, Chaochen; Atit, Radhika P; Wong, Sunny Y; Brownell, Isaac
2016-07-01
The Sonic hedgehog (Shh) signaling pathway regulates developmental, homeostatic, and repair processes throughout the body. In the skin, touch domes develop in tandem with primary hair follicles and contain sensory Merkel cells. The developmental signaling requirements for touch dome specification are largely unknown. We found dermal Wnt signaling and subsequent epidermal Eda/Edar signaling promoted Merkel cell morphogenesis by inducing Shh expression in early follicles. Lineage-specific gene deletions revealed intraepithelial Shh signaling was necessary for Merkel cell specification. Additionally, a Shh signaling agonist was sufficient to rescue Merkel cell differentiation in Edar-deficient skin. Moreover, Merkel cells formed in Fgf20 mutant skin where primary hair formation was defective but Shh production was preserved. Although developmentally associated with hair follicles, fate mapping demonstrated Merkel cells primarily originated outside the hair follicle lineage. These findings suggest that touch dome development requires Wnt-dependent mesenchymal signals to establish reciprocal signaling within the developing ectoderm, including Eda signaling to primary hair placodes and ultimately Shh signaling from primary follicles to extrafollicular Merkel cell progenitors. Shh signaling often demonstrates pleiotropic effects within a structure over time. In postnatal skin, Shh is known to regulate the self-renewal, but not the differentiation, of touch dome stem cells. Our findings relate the varied effects of Shh in the touch dome to the ligand source, with locally produced Shh acting as a morphogen essential for lineage specification during development and neural Shh regulating postnatal touch dome stem cell maintenance.

Introduction Respiratory tract infections (RTIs) are the most common reason for primary care (PC) consultations and for antibiotic prescribing and use. The majority of RTIs have a viral aetiology however, and antibiotic consumption is ineffective and unnecessary. Inappropriate antibiotic use contributes greatly to antibiotic resistance (ABR) leading to complications, increased adverse events, reconsultations and costs. Improving antibiotic consumption is thus crucial to containing ABR, which has become an urgent priority worldwide. We will systematically review the evidence about interventions aimed at improving the quality of antibiotic prescribing and use for acute RTI. Methods and analysis We will include primary peer-reviewed and grey literature of studies conducted on in-hours and out-of-hours PC patients (adults and children): (1) randomised controlled trials (RCTs), quasi-RCTs and/or cluster-RCTs evaluating the effectiveness, feasibility and acceptability of patient-targeted and clinician-targeted interventions and (2) RCTs and other study designs evaluating the effectiveness of public campaigns and regulatory interventions. We will search MEDLINE (EBSCOHost), EMBASE (Elsevier), the Cochrane Library (Wiley), CINHAL (EBSCOHost), PsychINFO (EBSCOHost), Web of Science, LILACS (Latin American and Caribbean Literature on Health Sciences), TRIP (Turning Research Into Practice) and opensgrey.eu without language restriction. We will also search the reference lists of included studies and relevant reviews. Primary outcomes include the rates of (guideline-recommended) antibiotics prescribed and/or used. Secondary outcomes include immediate or delayed use of antibiotics, and feasibility and acceptability outcomes. We will assess study eligibility and risk of bias, and will extract data. Data permitting, we will perform meta-analyses. Ethics and dissemination This is a systematic review protocol and so formal ethical approval is not required. We will not collect confidential, personal or primary data. The findings of this review will be disseminated at national and international scientific meetings. Trial registration number PROSPERO trial (CRD42017035305). PMID:28611111

Thanks to the work of politics and religion scholars, we now know a lot about the relationship between religion and voting in American presidential general elections. However, we know less about the influence of religion on individual vote choice in presidential primaries. This article fills that gap by exploring the relationship between religion and candidate preference in the 2008 and 2012 Republican primaries. Using pre-Super Tuesday surveys conducted by the Pew Research Center, I find that the Republican candidate who most explicitly appealed to religious voters (Mike Huckabee in 2008 and Rick Santorum in 2012) was the preferred candidate of Republican respondents who attended religious services at the highest levels, and that as attendance increased, so did the likelihood of preferring that candidate. I also find that identification as a born again Christian mattered to candidate preference. Specifically, born again Christians were more likely than non-born again Christians to prefer Huckabee to Mitt Romney, John McCain and Ron Paul in 2008, and Santorum to Romney in 2012. Although ideology was not the primary subject of this article, I find that ideology was also a statistically significant predictor of Republican candidate preference in both 2008 and 2012. This robust finding reinforces scholars’ prior work on the importance of ideology in explaining presidential primary vote choice. The overall findings of the paper provide evidence that religion variables can add to our understanding of why voters prefer one candidate over another in presidential primaries. PMID:27043438

This paper examines the indirect costs of primary care residency in terms of ambulatory care site productivity and the influence of graduate medical education (GME) subsidies on the employment of primary care residents. Using a sample of hospitals and health centers in New York City (NYC), we find that most facilities employ significantly more primary care residents relative to nonresident primary care physicians than would be dictated by cost-minimizing behavior in the production of primary care. We also find evidence that New York's GME subsidy encourages the "overemployment" of residents, while the Medicare GME subsidy does not. We conclude that the trade-off between productivity and teaching is more serious in primary care than in inpatient settings, and that facilities heavily involved in ambulatory care teaching will be at a competitive disadvantage if GME subsidies are not targeted specifically for primary care.

Kallery, Maria; Loupidou, Thomais
2016-06-01
The present study examines how the overall cognitive achievements in science of the younger children in a class where the students work in small multi-age groups are influenced by the number of older children in the groups. The context of the study was early-years education. The study has two parts: The first part involved classes attended by pre-primary children aged 4-6. The second part included one primary class attended by students aged 6-8 in addition to the pre-primary classes. Students were involved in inquiry-based science activities. Two sources of data were used: Lesson recordings and children's assessments. The data from both sources were separately analyzed and the findings plotted. The resulting graphs indicate a linear relationship between the overall performance of the younger children in a class and the number of older ones participating in the groups in each class. It seems that the age composition of the groups can significantly affect the overall cognitive achievements of the younger children and preferentially determines the time within which this factor reaches its maximum value. The findings can be utilized in deciding the age composition of small groups in a class with the aim of facilitating the younger children's learning in science.

Routine Cross-Sectional Head Imaging Before Electroconvulsive Therapy: A Tertiary Center Experience.
Sajedi, Payam I; Mitchell, Jason; Herskovits, Edward H; Raghavan, Prashant
2016-04-01
Electroconvulsive therapy (ECT) is generally contraindicated in patients with intracranial mass lesions or in the presence of increased intracranial pressure. The purpose of this study was to determine the prevalence of incidental abnormalities on routine cross-sectional head imaging, including CT and MRI, that would preclude subsequent ECT. This retrospective study involved a review of the electronic medical records of 105 patients (totaling 108 imaging studies) between April 27, 2007, and March 20, 2015, referred for cranial CT or MRI with the primary indication of pre-ECT evaluation. The probability of occurrence of imaging findings that would preclude ECT was computed. A cost analysis was also performed on the practice of routine pre-ECT imaging. Of the 105 patients who presented with the primary indication of ECT clearance (totaling 108 scans), 1 scan (0.93%) revealed findings that precluded ECT. None of the studies demonstrated findings that indicated increased intracranial pressure. A cost analysis revealed that at least $18,662.70 and 521.97 relative value units must be expended to identify one patient with intracranial pathology precluding ECT. The findings of this study demonstrate an extremely low prevalence of findings that preclude ECT on routine cross-sectional head imaging. The costs incurred in identifying a potential contraindication are high. The authors suggest that the performance of pre-ECT neuroimaging be driven by the clinical examination.

Background Evidence supports the implementation of primary prevention and health promotion (PP&HP) activities but primary care (PC) professionals show resistance to implementing these activities. The aim was to synthesize the available qualitative research on barriers and facilitators identified by PC physicians and nurses in the implementation of PP&HP in adults. Methods and Findings A systematic search of three databases was conducted and supported by manual searches. The 35 articles included were translated into each other and a new interpretation of the concepts extracted was generated. The factors affecting the implementation of PP&HP activities in PC according to professionals were fitted into a five-level ecological model: intrapersonal factors, interpersonal processes, institutional factors, community factors and public policy. At the intrapersonal level we find professionals' beliefs about PP&HP, experiences, skills and knowledge, and selfconcept. The attitudes and behavior towards PP&HP of patients, specialists, practice managers and colleagues (interpersonal factors) affect the feasibility of implementing PP&HP. Institutional level: PC is perceived as well-placed to implement PP&HP but workload, lack of time and referral resources, and the predominance of the biomedical model (which prioritizes disease treatment) hamper the implementation of PP&HP. The effectiveness of financial incentives and tools such as guidelines and alarms/reminders is conditioned by professionals' attitudes to them. Community factors include patients' social and cultural characteristics (religion, financial resources, etc.), local referral resources, mass-media messages and pharmaceutical industry campaigns, and the importance given to PP&HP in the curriculum in university. Finally, policies affect the distribution of resources, thus affecting the implementation of PP&HP. Conclusions Research on barriers and facilitators in the implementation of PP&HP activities in multirisk management is scarce. The conceptual overview provided by this synthesis resulted in the development of practical recommendations for the design of PP&HP in PC. However, the effectiveness of these recommendations needs to be demonstrated. PMID:24586867

This article describes findings from a qualitative policy study focused on female nurses' activism in relation to lesbian health. Critical feminist analysis and comparative life history methodology were applied to career histories obtained from 10 diversely situated female nurses across Ontario, Canada. The findings show that nursing activist practices are informed by advocacy experiences that foster inclusive professional and community education plus formal education processes that shape their political socialization. Implications for nursing theory include the development of political knowledges and practices that support caring science, sociopolitical knowing, and primary healthcare nursing practice in a community context.

Functional abdominal pain in childhood: background studies and recent research trends.
Levy, Rona L; van Tilburg, Miranda A L
2012-01-01
The present review summarizes many of the major research trends investigated in the past five years regarding pediatric functional abdominal pain, and also summarizes the primary related findings from the authors' research program. Specific areas discussed based on work within the authors' group include familial illness patterns, genetics, traits, and mechanisms or processes related to abdominal pain. Topics covered from research published in the past five years include prevalence and cost, longitudinal follow-up, overlap with other disorders, etiology and mechanisms behind functional abdominal pain and treatment studies. It is hoped that findings from this work in abdominal pain will be interpreted as a framework for understanding the processes by which other pain phenomena and, more broadly, reactions to any physical state, can be developed and maintained in children. The present article concludes with recommendations for clinical practice and research.

Time providing care outside visits in a home-based primary care program
Pedowitz, Elizabeth J.; Ornstein, Katherine A.; Farber, Jeffrey; DeCherrie, Linda V.
2016-01-01
Background/Objectives Homebound elderly patients with chronic medical illnesses face multiple barriers to care. Primary care physicians (PCPs) devote a significant amount of time to care apart from actual office visits, but there is little quantification of such time by physicians who provide primary care in the home. This article assesses exactly how much time physicians in a large home based primary care (HBPC) program spend providing care outside of home visits. Unreimbursed time, as well as patient and provider-related factors that may contribute to that increased time, are considered. Design Mount Sinai Visiting Doctors (MSVD) providers filled out research forms for every interaction involving care provision outside of home visits. Data collected included: length of interaction, mode, nature, and whom the interaction was with for 3 weeks. Setting/Participants MSVD is an academic home-visit program in Manhattan, NY. All PCPs in MSVD (n=14) agreed to participate. Measurements Time data were analyzed using a comprehensive estimate and conservative estimates to quantify unbillable time. Results Data on 1151 interactions for 537 patients were collected. An average 8.2 hours/week were spent providing non-home visit care for a full-time provider. Using the most conservative estimates, 3.6 hours/week was estimated to be unreimbursed per full-time provider. No significant differences in interaction times were found among dementia vs. non-dementia patients, new vs. non-new patients, and primary-panel vs. covered patients. Conclusion Findings suggest that HBPC providers spend substantial time providing care outside home visits, much of which goes unrecognized in the current reimbursement system. These findings may help guide practice development and creation of new payment systems for HBPC and similar models of care. PMID:24802078

Our recent experience with a patient developing cutaneous metastases within 3 months of diagnosis of esophageal adenocarcinoma suggests that altered expression of the cellular adhesion molecules, E-cadherin and CD44v6, may have had a role to play in the rapid onset of metastases. To corroborate these findings, we designed a cross-sectional study to investigate the expression of select molecules involved in the metastatic cascade. E-cadherin, beta-catenin, CD44v6, and HER2/neu immunohistochemical stains were performed on archival materials of metastatic adenocarcinoma to the skin from 27 patients and the available corresponding primary tumors in 10 patients. The primary sites included breast (n = 10; 37%), gastrointestinal tract (n = 10; 37%), ovary (n = 1; 4%), thyroid (n = 2; 7%), lung (n = 1; 4%), and unknown primary (n = 3; 11%). Expression of all markers was noted with the most significant increases observed in beta-catenin (26 of 27 cases; 96%), followed by CD44v6 (24 of 27 cases; 89%), E-cadherin (22 of 27 cases; 82%), and HER2/neu (11 of 27 cases; 41%). Contrasting expression of these molecules in the primary versus the metastatic tumors, enhanced expression of CD44v6 was observed in the cutaneous metastases relative to the primary in 6 of 10 (60%) cases. Of interest, 2 of these 6 cases (33%) also showed reduction in E-cadherin--a member of the cadherin family functioning as an invasion suppressor molecule. These findings reinforce the complexities of the metastatic cascade and imply that the variation in adhesive properties of tumor cells is, perhaps, a consequence of the difference in density of the molecules mediating this process.

To investigate and compare the diagnostic values of bronchoscopy and multi-slice spiral computed tomography (CT) for congenital dysplasia of the respiratory system in infants. Analysis was performed on the clinical data, bronchoscopic findings and multi-slice spiral CT findings of 319 infants (≤1 years old) who underwent bronchoscopy and/or multi-slice spiral CT and were diagnosed with congenital dysplasia of the respiratory system. A total of 476 cases of congenital dysplasia of the respiratory system were found in the 319 infants, including primary dysplasia of the respiratory system (392 cases) and compressive dysplasia of the respiratory system (84 cases). Of the 392 cases of primary dysplasia of the respiratory system, 225 (57.4%) were diagnosed by bronchoscopy versus 167 (42.6%) by multi-slice spiral CT. There were significant differences in etiological diagnosis between bronchoscopy and multi-slice spiral CT in infants with congenital dysplasia of the respiratory system (P<0.05). All 76 cases of primary dysplasia of the respiratory system caused by tracheobronchomalacia were diagnosed by bronchoscopy and all 17 cases of primary dysplasia of the respiratory system caused by lung tissue dysplasia were diagnosed by multi-slice spiral CT. Of the 84 cases of compressive dysplasia of the respiratory system, 74 cases were diagnosed by multi-slice spiral CT and only 10 cases were diagnosed by bronchoscopy. Compared with multi-slice spiral CT, bronchoscopy can detect primary dysplasia of the respiratory system more directly. Bronchoscopy is valuable in the confirmed diagnosis of tracheobronchomalacia. Multi-slice spiral CT has a higher diagnostic value for lung tissue dysplasia than bronchoscopy.

Traditional spinal cord stimulation (SCS) requires that paresthesia overlaps chronic painful areas. However, the new paradigm high-frequency SCS (HF-SCS) does not rely on paresthesia. A review of preclinical and clinical studies regarding the use of paresthesia-free HF-SCS for various chronic pain states. We reviewed available literatures on HF-SCS, including Nevro's paresthesia-free ultra high-frequency 10 kHz therapy (HF10-SCS). Data sources included relevant literature identified through searches of PubMed, MEDLINE/OVID, and SCOPUS, and manual searches of the bibliographies of known primary and review articles. The primary goal is to describe the present developing conceptions of preclinical mechanisms of HF-SCS and to review clinical efficacy on paresthesia-free HF10-SCS for various chronic pain states. HF10-SCS offers a novel pain reduction tool without paresthesia for failed back surgery syndrome and chronic axial back pain. Preclinical findings indicate that potential mechanisms of action for paresthesia-free HF-SCS differ from those of traditional SCS. To fully understand and utilize paresthesia-free HF-SCS, mechanistic study and translational research will be very important, with increasing collaboration between basic science and clinical communities to design better trials and optimize the therapy based on mechanistic findings from effective preclinical models and approaches. Future research in these vital areas may include preclinical and clinical components conducted in parallel to optimize the potential of this technology. © 2017 International Neuromodulation Society.

Parenting Stress and Emotional/Behavioral Problems in Adolescents with Primary Headache.
Operto, Francesca Felicia; Craig, Francesco; Peschechera, Antonia; Mazza, Roberta; Lecce, Paola Alessandra; Margari, Lucia
2017-01-01
Primary headache is a frequent and disabling disorder, common among children and adolescents, and it is a painful syndrome often accompanied by functional impairment and associated with emotional and behavior problems. The aim of this study was to investigate parenting stress and emotional/behavioral problems in adolescents affected by primary headache compared with healthy adolescents. The study population consisted of 35 adolescents and a control group of 23 healthy subjects. The assessment included the administration of clinical standardized scales such as Parent Stress Index-Short Form, Pediatric Migraine Disability Assessment Score Questionnaire, and Child Behavior Checklist (CBCL). Headache group and control group did not differ in terms of parenting stress ( p = 0.29). On the contrary, headache group showed more internalizing problems ( p = 0.023), affective problems ( p = 0.01), anxious ( p = 0.001), and somatic complaints ( p < 0.001) compared with control group. In addition, we found a significant correlation between PSI domains and specific CBCL subscales in the headache group. The findings emphasize the need for expanded intervention in the clinical treatment of pediatric headache, a treatment that may also include the family members. Further research is needed.

The management of diagnosed heart failure in older people in primary care.
Jones, Nicholas R; Hobbs, F D Richard; Taylor, Clare J
2017-12-01
Heart failure (HF) is a common condition affecting predominantly older people. Symptoms include breathlessness and fatigue, and can significantly reduce quality of life. HF rarely occurs in isolation, with most patients having several co-existing diseases requiring multiple medications. There is a large evidence base for treatment of HF with reduced ejection fraction, or HFrEF; however, many of the trials did not include older people with multimorbidity so their findings should be applied to this group with some caution. The evidence for treatment of HF with preserved ejection fraction, or HFpEF, is much less well established in all age groups. Older people with HF are usually managed in primary care with input from specialist HF teams when needed. General practitioners are trained to take a generalist approach, which allows them to deliver holistic, person-centred care. The wider multidisciplinary team is also important during the patient's HF journey, with a particular need to consider palliative care towards the end of life. This article summarises the important aspects of HF management in older people from the perspective of primary care. Copyright © 2017 Elsevier B.V. All rights reserved.

Intraosseous salivary gland carcinomas are extremely rare, comprising only 2% to 3% of all mucoepidermoid carcinomas (MECs) reported. The t(11;19) translocation and its CRTC1/MAML1 fusion transcript have been identified in MEC at different sites and are believed to be associated with the development of a subset of these tumors. However, the status of the fusion transcript has not been reported in intraosseous MEC. Here, we report 3 examples of central MEC of the mandible, including a case with a history of primary retromolar MEC. Reverse transcriptase-polymerase chain reaction and DNA sequencing analyses of the microdissected components of these tumors were used for the detection and verification of the fusion transcript. We identified, for the first time, the t(11;19) fusion gene transcript in central MEC, including in the previous primary retromolar MEC. No fusion transcript was detected in the second primary noncentral MEC or in another central MEC. The results indicate that central MEC can manifest the fusion transcript. This finding may have diagnostic and histogenetic roles in the future analysis of this entity. Published by Elsevier Inc.

Opportunity Knocks: HIV Prevention in Primary Care.
Thrun, Mark W
2014-06-01
Expansions in health care coverage, a comprehensive framework for HIV prevention and care, electronic medical records, and novel HIV prevention modalities create a current opportunity to change the trajectory of the HIV epidemic in the United States. HIV is increasingly disproportionately found in populations historically at higher risk, including gay men and other men who have sex with men, transgender women, injection drug users, and persons of color. This underscores the need for providers to identify persons at higher risk for HIV and assure the provision of screening and prevention services. In turn, universal screening for HIV-testing every adolescent and adult at least once in their lifetime-will increasingly be necessary to find the infrequent cases of HIV in lower risk populations. In both these domains, primary care providers will play a unique role in complementing traditional providers of HIV prevention and care services by increasing the proportion of their patients who have been screened for HIV, opening dialogues around sexual health, including asking about sexual orientation and gender identity, and prescribing antivirals as pre- and postexposure prophylaxis for their non-HIV-infected patients. Primary care providers must understand and embrace their importance along the HIV prevention and care continuum.

Voltage-gated sodium channels (Navs) comprise at least nine pore-forming α subunits. Of these, Nav1.6, Nav1.7, Nav1.8 and Nav1.9 are the most frequently studied in primary sensory neurons located in the dorsal root ganglion and are mainly localized to the cytoplasm. A large pool of intracellular Navs raises the possibility that changes in Nav trafficking could alter channel function. The molecular mediators of Nav trafficking mainly consist of signals within the Navs themselves, interacting proteins and extracellular factors. The surface expression of Navs is achieved by escape from the endoplasmic reticulum and proteasome degradation, forward trafficking and plasma membrane anchoring, and it is also regulated by channel phosphorylation and ubiquitination in primary sensory neurons. Axonal transport and localization of Navs in afferent fibers involves the motor protein KIF5B and scaffold proteins, including contactin and PDZ domain containing 2. Localization of Nav1.6 to the nodes of Ranvier in myelinated fibers of primary sensory neurons requires node formation and the submembrane cytoskeletal protein complex. These findings inform our understanding of the molecular and cellular mechanisms underlying Nav trafficking in primary sensory neurons.

Research has provided evidence that the effects of intergroup contact on prejudice reduction are not limited to the outgroup one has contact with (primary outgroup). Rather, they extend to secondary outgroups uninvolved in the contact situation (secondary transfer effect; Pettigrew, 2009, Social Psychology, 40, 55). We aimed to provide the first empirical evidence for the emergence of the secondary transfer effect among children. Majority (Italian) and minority (with an immigrant background) elementary schoolchildren were administered a questionnaire including measures of contact with the primary outgroup (minority children for the majority, majority children for the minority), prejudice towards the primary outgroup and towards a dissimilar secondary outgroup (disabled children), and social dominance orientation. Results revealed that among the majority group, contact with the primary outgroup had indirect associations with reduced prejudice towards the secondary outgroup. Specifically, we found evidence for sequential mediation by social dominance orientation and prejudice towards the primary outgroup. No secondary transfer effects emerged among minority group members. We discuss theoretical and practical implications of the findings, arguing for the importance of identifying the core processes driving the secondary transfer effect. © 2018 The British Psychological Society.

Connectionist theories of language propose that written language deficits arise as a result of damage to semantic and phonological systems that also support spoken language production and comprehension, a view referred to as the "primary systems" hypothesis. The objective of the current study was to evaluate the primary systems account in a mixed group of individuals with primary progressive aphasia (PPA) by investigating the relation between measures of nonorthographic semantic and phonological processing and written language performance and by examining whether common patterns of cortical atrophy underlie impairments in spoken versus written language domains. Individuals with PPA and healthy controls were administered a language battery, including assessments of semantics, phonology, reading, and spelling. Voxel-based morphometry was used to examine the relation between gray matter volumes and language measures within brain regions previously implicated in semantic and phonological processing. In accordance with the primary systems account, our findings indicate that spoken language performance is strongly predictive of reading/spelling profile in individuals with PPA and suggest that common networks of critical left hemisphere regions support central semantic and phonological processes recruited for spoken and written language.

Objective: The objective of this study was to compare the clinical and radiographic effects of Allium sativum oil and formocresol in nonvital pulpotomy in primary teeth. Materials and Methods: Twenty children ranging in age from 4 to 8 years were included in the study. In every one of those children, pulpotomy was indicated for the primary molars. Pulpotomy procedure was performed and the radicular pulp tissue of one molar was capped with A. sativum oil in a cotton pellet while the other molar was capped with formocresol. The teeth were evaluated clinically and radiographically before and after 6 months using standard clinical and radiographic criteria. Statistically, these results revealed significant difference between the radiographic findings of nonvital pulpotomy in primary molars with the two medicaments. Statistical analysis was performed using independent t-test and paired t-test at the significance level of α = 0.05. Results: A. sativum oil has potent antibacterial properties that enable it to combat intracanal microbes in the infected pulp of primary molars. Better results were obtained when A. sativum oil was used. Conclusion: A. sativum oil had more powerful effects than formocresol on the infected pulp of primary nonvital molars. PMID:26312232

Aligning provider incentives to improve primary healthcare delivery in the United States
DeVoe, JE; Stenger, R
2016-01-01
Background The United States (US) is reforming primary care delivery systems, including the implementation of ‘patient-centered medical homes.’ Alignment of provider incentives with desired outcomes will likely be important to the success of these delivery system reforms. Methods This critical review uses a theoretical framework from game-theory models to discuss some of the dominant primary care provider payment models and how they create ‘prisoner’s dilemmas’ that have stalled past reform efforts. It then uses this framework to illustrate, hypothetically, how advantages from different models could be blended together to encourage cooperation and improve the quality of primary care services delivered, thus providing an escape from current prisoner’s dilemmas faced by providers. Findings Improvements in primary care delivery will largely hinge on blended payment mechanisms that can effectively combine the advantageous elements of fee-for-service, capitation, and incentive payments into a balanced equation that enables providers to escape the perverse financial incentives of current payment mechanisms and overcome collective action problems. Conclusions If balanced appropriately, a blend of guaranteed payment and selective incentives designed to encourage primary care providers to deliver high quality care, efficient and equitable care and to eliminate incentives towards over-servicing could reach outcomes leading to shared benefits for everyone involved.

In static SIMS, the secondary ion yield, defined as detected ions per primary ion, can be increased by altering several primary ion parameters. For many years, no quantitative predictions could be made for the secondary ion yield enhancement of molecular ions. For thick samples of organic compounds, a power dependency of the secondary ion yield on the sputtering yield was shown. For this article, samples with thick molecular layers and (sub-)monolayers composed of various molecules were prepared on inorganic substrates such as silicon, silver, and gold, and subsequently analyzed. For primary ion bombardment, monoatomic (Ne+, Ar+, Ga+, Kr+, Xe+, Bi+) as well as polyatomic (Bin+, Bin++) primary ions were used within an energy range of 10-50 keV. The power dependency was found to hold true for the different samples; however, the exponent decreased with increasing stopping power. Based on these findings, a rule of thumb is proposed for the prediction of the lower limit of the secondary ion yield enhancement as a function of the primary ion species. Additionally, effects caused by the variation of the energy deposition are discussed, including the degree of molecular fragmentation and the non-linear increase of the secondary ion yield when polyatomic primary ions are used.

Consensus United States cervical cancer screening guidelines recommend use of combination Pap plus human papillomavirus (HPV) testing for women aged 30 to 65 years. An HPV test was approved by the Food and Drug Administration in 2014 for primary cervical cancer screening in women age 25 years and older. Here, we present the results of clinical-economic comparisons of Pap plus HPV mRNA testing including genotyping for HPV 16/18 (co-testing) versus DNA-based primary HPV testing with HPV 16/18 genotyping and reflex cytology (HPV primary) for cervical cancer screening. A health state transition (Markov) model with 1-year cycling was developed using epidemiologic, clinical, and economic data from healthcare databases and published literature. A hypothetical cohort of one million women receiving triennial cervical cancer screening was simulated from ages 30 to 70 years. Screening strategies compared HPV primary to co-testing. Outcomes included total and incremental differences in costs, invasive cervical cancer (ICC) cases, ICC deaths, number of colposcopies, and quality-adjusted life years for cost-effectiveness calculations. Comprehensive sensitivity analyses were performed. In a simulation cohort of one million 30-year-old women modeled up to age 70 years, the model predicted that screening with HPV primary testing instead of co-testing could lead to as many as 2,141 more ICC cases and 2,041 more ICC deaths. In the simulation, co-testing demonstrated a greater number of lifetime quality-adjusted life years (22,334) and yielded $39.0 million in savings compared with HPV primary, thereby conferring greater effectiveness at lower cost. Model results demonstrate that co-testing has the potential to provide improved clinical and economic outcomes when compared with HPV primary. While actual cost and outcome data are evaluated, these findings are relevant to U.S. healthcare payers and women's health policy advocates seeking cost-effective cervical cancer screening technologies.

Background After many years of sanctions and conflict, Iraq is rebuilding its health system, with a strong emphasis on the traditional hospital-based services. A network exists of public sector hospitals and clinics, as well as private clinics and a few private hospitals. Little data are available about the approximately 1400 Primary Health Care clinics (PHCCs) staffed with doctors. How do Iraqis utilize primary health care services? What are their preferences and perceptions of public primary health care clinics and private primary care services in general? How does household wealth affect choice of services? Methods A 1256 household national survey was conducted in the catchment areas of randomly selected PHCCs in Iraq. A cluster of 10 households, beginning with a randomly selected start household, were interviewed in the service areas of seven public sector PHCC facilities in each of 17 of Iraq's 18 governorates. A questionnaire was developed using key informants. Teams of interviewers, including both males and females, were recruited and provided a week of training which included field practice. Teams then gathered data from households in the service areas of randomly selected clinics. Results Iraqi participants are generally satisfied with the quality of primary care services available both in the public and private sector. Private clinics are generally the most popular source of primary care, however the PHCCs are utilized more by poorer households. In spite of free services available at PHCCs many households expressed difficulty in affording health care, especially in the purchase of medications. There is no evidence of informal payments to secure health services in the public sector. Conclusions There is widespread satisfaction reported with primary health care services, and levels did not differ appreciably between public and private sectors. The public sector PHCCs are preferentially used by poorer populations where they are important providers. PHCC services are indeed free, with little evidence of informal payments to providers.

Background: As the organization of primary care continues to evolve toward more interdisciplinary team structures, demonstrating effectiveness of care delivery is becoming important, particularly for nonphysician providers. Nurses are the most common nonphysician provider within primary care. The purpose of this study was to examine the relation between primary care delivery models that incorporate registered nurses and clinical outcomes of patients with type 2 diabetes. Methods: Patient data from the Canadian Primary Care Sentinel Surveillance Network were matched with survey data from 15 Family Health Team practices in southeastern Ontario. Included patients were adults with type 2 diabetes mellitus who had at least 1 primary care encounter at a Family Health Team practice that completed the organizational survey between Apr. 1, 2013, and Mar. 31, 2014. The clinical outcomes explored included hemoglobin A1c, fasting plasma glucose, blood pressure, low-density lipoprotein cholesterol and urine albumin:creatinine ratio. Results: Of the 15 practices, 13 (86.7%) had at least 1 registered nurse. The presence of 1 or more registered nurses in the practice was associated with increased odds of patients' having their hemoglobin A1c, fasting plasma glucose, blood pressure and low-density lipoprotein cholesterol values meet recommended targets. Practices with the lowest ratios of patients with diabetes to registered nurse had a significantly greater proportion of patients with hemoglobin A1c and fasting plasma glucose values on target than did practices with the highest ratios of patients to registered nurse (p < 0.01 and p = 0.03, respectively). Interpretation: The findings suggest that registered nurse staffing within primary care practice teams contributes to better diabetic care, as measured by diabetes management indicators. This study sets the groundwork for further exploration of nursing and organizational contributions to patient care in the primary care setting. PMID:27398372

Networks In ACA Marketplaces Are Narrower For Mental Health Care Than For Primary Care.
Zhu, Jane M; Zhang, Yuehan; Polsky, Daniel
2017-09-01
There is increasing concern about the extent to which narrow-network plans, generally defined as those including fewer than 25 percent of providers in a given health insurance market, affect consumers' choice of and access to specialty providers-particularly in mental health care. Using data for 2016 from 531 unique provider networks in the Affordable Care Act Marketplaces, we evaluated how network size and the percentage of providers who participate in any network differ between mental health care providers and a control group of primary care providers. Compared to primary care networks, participation in mental health networks was low, with only 42.7 percent of psychiatrists and 19.3 percent of nonphysician mental health care providers participating in any network. On average, plan networks included 24.3 percent of all primary care providers and 11.3 percent of all mental health care providers practicing in a given state-level market. These findings raise important questions about provider-side barriers to meeting the goal of mental health parity regulations: that insurers cover mental health services on a par with general medical and surgical services. Concerted efforts to increase network participation by mental health care providers, along with greater regulatory attention to network size and composition, could improve consumer choice and complement efforts to achieve mental health parity.

Objectives Pharmacists and general practitioners (GPs) face an increasing expectation to collaborate interprofessionally on a number of healthcare issues, including medication non-adherence. This study aimed to propose a model of interprofessional collaboration within the context of identifying and improving medication non-adherence in primary care. Setting Primary care; Sydney, Australia. Participants 3 focus groups were conducted with pharmacists (n=23) and 3 with GPs (n=22) working in primary care. Primary and secondary outcome measures Qualitative investigation of GP and pharmacist interactions with each other, and specifically around supporting their patients’ medication adherence. Audio-recordings were transcribed verbatim and transcripts thematically analysed using a combination of manual and computer coding. Results 3 themes pertaining to interprofessional collaboration were identified (1) frequency, (2) co-collaborators and (3) nature of communication which included 2 subthemes (method of communication and type of communication). While the frequency of interactions was low, the majority were conducted by telephone. Interactions, especially those conducted face-to-face, were positive. Only a few related to patient non-adherence. The findings are positioned within contemporary collaborative theory and provide an accessible introduction to models of interprofessional collaboration. Conclusions This work highlighted that successful collaboration to improve medication adherence was underpinned by shared paradigmatic perspectives and trust, constructed through regular, face-to-face interactions between pharmacists and GPs.

Despite its importance, the integration of oral health into primary care is still an emerging practice in the field of health care services. This scoping review aims to map the literature and provide a summary on the conceptual frameworks, policies and programs related to this concept. Using the Levac et al. six-stage framework, we performed a systematic search of electronic databases, organizational websites and grey literature from 1978 to April 2016. All relevant original publications with a focus on the integration of oral health into primary care were retrieved. Content analyses were performed to synthesize the results. From a total of 1619 citations, 67 publications were included in the review. Two conceptual frameworks were identified. Policies regarding oral heath integration into primary care were mostly oriented toward common risk factors approach and care coordination processes. In general, oral health integrated care programs were designed in the public health sector and based on partnerships with various private and public health organizations, governmental bodies and academic institutions. These programmes used various strategies to empower oral health integrated care, including building interdisciplinary networks, training non-dental care providers, oral health champion modelling, enabling care linkages and care coordinated process, as well as the use of e-health technologies. The majority of studies on the programs outcomes were descriptive in nature without reporting long-term outcomes. This scoping review provided a comprehensive overview on the concept of integration of oral health in primary care. The findings identified major gaps in reported programs outcomes mainly because of the lack of related research. However, the results could be considered as a first step in the development of health care policies that support collaborative practices and patient-centred care in the field of primary care sector.

Contracting with private providers for primary care services: evidence from urban China.
Wang, Yan; Eggleston, Karen; Yu, Zhenjie; Zhang, Qiong
2013-01-17
Controversy surrounds the role of the private sector in health service delivery, including primary care and population health services. China's recent health reforms call for non-discrimination against private providers and emphasize strengthening primary care, but formal contracting-out initiatives remain few, and the associated empirical evidence is very limited. This paper presents a case study of contracting with private providers for urban primary and preventive health services in Shandong Province, China. The case study draws on three primary sources of data: administrative records; a household survey of over 1600 community residents in Weifang and City Y; and a provider survey of over 1000 staff at community health stations (CHS) in both Weifang and City Y. We supplement the quantitative data with one-on-one, in-depth interviews with key informants, including local officials in charge of public health and government finance.We find significant differences in patient mix: Residents in the communities served by private community health stations are of lower socioeconomic status (more likely to be uninsured and to report poor health), compared to residents in communities served by a government-owned CHS. Analysis of a household survey of 1013 residents shows that they are more willing to do a routine health exam at their neighborhood CHS if they are of low socioeconomic status (as measured either by education or income). Government and private community health stations in Weifang did not statistically differ in their performance on contracted dimensions, after controlling for size and other CHS characteristics. In contrast, the comparison City Y had lower performance and a large gap between public and private providers. We discuss why these patterns arose and what policymakers and residents considered to be the main issues and concerns regarding primary care services.

Chronic substance use and self-harm in a primary health care setting.
Breet, Elsie; Bantjes, Jason; Lewis, Ian
2018-06-19
Chronic substance use (CSU) is associated with health problems, including selfharm, placing a significant burden on health care resources and emergency departments (EDs). This is problematic in low- and middle-income countries like South Africa (SA), where primary care facilitates and emergency departments (EDs) are often poorly resourced. To investigate the epidemiology of CSU and self-harm and to consider the implications for primary health care service delivery and suicide prevention in SA. Data were collected from 238 consecutive self-harm patients treated at the emergency department (ED) of an urban hospital in SA. The data were analysed using bivariate and multivariate analyses. Approximately 37% of self-harm patients reported CSU. The patients in the CSU subgroup, compared to other self-harm patients, were more likely to be men (odds ratio[OR] = 8.33, 95% confidence interval [CI] = 3.19-20.9, p < 0.001), to have self-harmed by inflicting damage to their body tissue OR = 4.45, 95% CI = 1.77-11.2, p < 0.01) and to have a history of self-harm (OR = 3.71, 95% CI = 1.44-9.54, p = 0.007). A significantly smaller proportion of CSU patients, compared to other self-harm patients, were referred for psychiatric assessment (OR = 8.05, 95% CI = 4.16-15.7, p < 0.001). The findings of this study confirm that CSU is associated with greater service utilisation and repetition of self-harm among patients in primary health care settings. Treating self-harm as the presenting problem within primary care settings does not necessarily ensure that patients receive the care that they need. It might be helpful to include psychiatric assessments and screening for CSU as an integral component of care for self-harm patientswho present in primary health care settings.

2015-02-01
Pharmacists have unique skills that may benefit primary care practices. The objective of this demonstration project was to determine the impact of integrating pharmacists into patient-centered medical homes, with a focus on population management. Pharmacists were partnered into 5 primary care practices in Vermont 1 day per week to provide direct patient care, population-based medication management, and prescriber education. The main measures included a description of drug therapy problems identified and cost avoidance models. The pharmacists identified 708 drug therapy problems through direct patient care (336/708; 47.5%), population-based strategies (276/708; 38.9%), and education (96/708; 13.6%). Common population-based strategies included adjusting doses and discontinuing unnecessary medications. Pharmacists' recommendations to correct drug therapy problems were accepted by prescribers 86% of the time, when data about acceptance were known. Of the 49 recommendations not accepted, 47/49 (96%) were population-based and 2/49 (4%) were related to direct patient care. The cost avoidance model suggests $2.11 in cost was avoided for every $1.00 spent on a pharmacist ($373,092/$176,690). There was clear value in integrating pharmacists into primary care teams. Their inclusion prevented adverse drug events, avoided costs, and improved patient outcomes. Primary care providers should consider pharmacists well suited to offer direct patient care, population-based management, and prescriber education to their practices. To be successful, pharmacists must have full permission to document findings in the primary care practices' electronic health records. Given that many pharmacist services do not involve billable activities, sustainability requires identifying alternative funding mechanisms that do not rely on a traditional fee-for-service approach.

Abstract Objective To assess primary care providers’ (PCPs’) experiences with, perceptions of, and desired role in personalized medicine, with a focus on cancer. Design Qualitative study involving focus groups. Setting Urban and rural interprofessional primary care team practices in Alberta and Ontario. Participants Fifty-one PCPs. Methods Semistructured focus groups were conducted and audiorecorded. Recordings were transcribed and analyzed using techniques informed by grounded theory including coding, interpretations of patterns in the data, and constant comparison. Main findings Five focus groups with the 51 participants were conducted; 2 took place in Alberta and 3 in Ontario. Primary care providers described limited experience with personalized medicine, citing breast cancer and prenatal care as main areas of involvement. They expressed concern over their lack of knowledge, in some circumstances relying on personal experiences to inform their attitudes and practice. Participants anticipated an inevitable role in personalized medicine primarily because patients seek and trust their advice; however, there was underlying concern about the magnitude of information and pace of discovery in this area, particularly in direct-to-consumer personal genomic testing. Increased knowledge, closer ties to genetics specialists, and relevant, reliable personalized medicine resources accessible at the point of care were reported as important for successful implementation of personalized medicine. Conclusion Primary care providers are prepared to discuss personalized medicine, but they require better resources. Models of care that support a more meaningful relationship between PCPs and genetics specialists should be pursued. Continuing education strategies need to address knowledge gaps including direct-to-consumer genetic testing, a relatively new area provoking PCP concern. Primary care providers should be mindful of using personal experiences to guide care. PMID:27737998

Aim To assess the role of breast US in diagnosing and classifying gynecomastia as the primary imaging modality and to compare US findings and classification system with the mammographic ones. Patients and methods 48 patients suspected of having gynecomastia underwent mammography and US. Two radiologists in consensus retrospectively evaluated mammograms and sonograms. Both US and mammographic images were evaluated categorizing gynecomastia into non-mass, nodular and flame shaped patterns. The two category assignations were compared in order to find any difference. The reference standard for both the classification systems was represented by the cytological examination in 18 out of 44 cases (41%) and the six-month US follow-up in the remaining cases. Results The US examination revealed pseudo-gynecomastia in 4/48 (8%) and true gynecomastia in the remaining 44 (92%). Gynecomastia was bilateral in 25/44 cases (57%) and unilateral in the remaining 19 (43%). The cases of true gynecomastia included non mass shape in 26/44 cases (59%), nodular shape in 12 (27%) and flame shape in 6 (14%). The mammographic examination revealed the same results as compared with US findings. 18/44 (41%) patients affected by nodular or dendritic gynecomastia underwent cytological examination confirming the presence of glandular tissue and the benign nature of the clinical condition. Conclusions US could be proposed as the primary imaging tool for diagnosing and classifying gynecomastia, avoiding unnecessary X-ray examinations or invasive procedures in case of diffuse gynecomastia. In case of nodular or dendritic patterns, biopsy remains mandatory for a definitive diagnosis. PMID:27734795

Weight maintenance as a tight rope walk - a Grounded Theory study.
Lindvall, Kristina; Larsson, Christel; Weinehall, Lars; Emmelin, Maria
2010-02-01
Overweight and obesity are considerable public health problems internationally as well as in Sweden. The long-term results of obesity treatment are modest as reported by other studies. The importance of extending the focus to not only comprise obesity treatment but also prevention of weight gain is therefore being emphasized. However, despite the suggested change in focus there is still no consensus on how to prevent obesity or maintain weight. This study reports findings from a qualitative study focusing on attitudes, behaviors and strategies important for primary weight maintenance in a middle-aged population. In depth interviews were conducted with 23 maintainers and four slight gainers in Sweden. The interviews were transcribed and an analysis of weight maintenance was performed using Grounded Theory. Based on the informants' stories, describing attitudes, behaviors and strategies of importance for primary weight maintenance, a model illustrating the main findings, was constructed. Weight maintenance was seen as "a tightrope walk" and four strategies of significance for this "tightrope walk" were described as "to rely on heritage", "to find the joy", "to find the routine" and "to be in control". Eleven "ideal types" were included in the model to illustrate different ways of relating to the main strategies. These "ideal types" described more specific attitudes and behaviors such as; eating food that is both tasteful and nutritious, and choosing exercise that provides joy. However, other somewhat contradictory behaviors were also found such as; only eating nutritious food regardless of taste, and being physically active to control stress and emotions. This study show great variety with regards to attitudes, strategies and behaviors important for weight maintenance, and considerations need to be taken before putting the model into practice. However, the results from this study can be used within primary health care by enhancing the understanding of how people differ in their relation to food and physical activity. It informs health personnel about the need to differentiate advices related to body weight, not only to different sub-groups of individuals aiming at losing weight but also to sub-groups of primary weight maintainers aiming at maintaining weight.

Health and access to care for undocumented migrants living in the European Union: a scoping review.
Woodward, Aniek; Howard, Natasha; Wolffers, Ivan
2014-10-01
Literature on health and access to care of undocumented migrants in the European Union (EU) is limited and heterogeneous in focus and quality. Authors conducted a scoping review to identify the extent, nature and distribution of existing primary research (1990-2012), thus clarifying what is known, key gaps, and potential next steps. Authors used Arksey and O'Malley's six-stage scoping framework, with Levac, Colquhoun and O'Brien's revisions, to review identified sources. Findings were summarized thematically: (i) physical, mental and social health issues, (ii) access and barriers to care, (iii) vulnerable groups and (iv) policy and rights. Fifty-four sources were included of 598 identified, with 93% (50/54) published during 2005-2012. EU member states from Eastern Europe were under-represented, particularly in single-country studies. Most study designs (52%) were qualitative. Sampling descriptions were generally poor, and sampling purposeful, with only four studies using any randomization. Demographic descriptions were far from uniform and only two studies focused on undocumented children and youth. Most (80%) included findings on health-care access, with obstacles reported at primary, secondary and tertiary levels. Major access barriers included fear, lack of awareness of rights, socioeconomics. Mental disorders appeared widespread, while obstetric needs and injuries were key reasons for seeking care. Pregnant women, children and detainees appeared most vulnerable. While EU policy supports health-care access for undocumented migrants, practices remain haphazard, with studies reporting differing interpretation and implementation of rights at regional, institutional and individual levels. This scoping review is an initial attempt to describe available primary evidence on health and access to care for undocumented migrants in the European Union. It underlines the need for more and better-quality research, increased co-operation between gatekeepers, providers, researchers and policy makers, and reduced ambiguities in health-care rights and obligations for undocumented migrants.

Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare but pathologically distinct breast tumor. There have been some case reports on primary MCA of the breast; however, they have all focused on pathologic findings. Here, we report the radiologic findings of two cases of MCA along with a review of the literature. Breast MCA shows a circumscribed mass with some calcifications on mammography, an intracystic solid mass without increased vascularity or a vascular stalk on ultrasound, and a heterogeneously enhancing mass within a rim-enhancing cyst with intermediate signal intensity on T2-weighted magnetic resonance imaging. These radiologic findings and the presence of mucin in the percutaneous biopsy specimen should suggest the possibility of MCA in the differential diagnosis of a breast tumor.

Participants' Voices From Within a Healthy Lifestyle Group.
Park, Tanya; Foster, Kim; Usher, Kim
2017-02-01
Weight gain is a serious health concern. People with mental illnesses are at increased risk of weight gain. The primary treatment is lifestyle changes such as increasing physical activity and dietary changes. This qualitative study explored the experience of people with schizophrenia who participated in a healthy lifestyle program. Four themes were identified. The findings indicate that benefits of the program were more than physical health improvements and included regular access to a health professional, gaining social relationships, and a sense of belonging. Future recommendations include retaining a group structure in lifestyle interventions to facilitate these additional benefits.

The clinical manifestations, diagnosis, and treatment of adrenal emergencies.
Tucci, Veronica; Sokari, Telematé
2014-05-01
Emergency medicine physicians should be able to identify and treat patients whose clinical presentations, including key historical, physical examination, and laboratory findings are consistent with diagnoses of primary, secondary, and tertiary adrenal insufficiency, adrenal crisis, and pheochromocytoma. Failure to make a timely diagnosis leads to increased morbidity and mortality. As great mimickers, adrenal emergencies often present with a constellation of nonspecific signs and symptoms that can lead even the most diligent emergency physician astray. The emergency physician must include adrenal emergencies in the differential diagnosis when encountering such clinical pictures. Copyright © 2014 Elsevier Inc. All rights reserved.

The Tunka Radio Extension (Tunka-Rex) is a radio detector at the TAIGA facility located in Siberia nearby the southern tip of Lake Baikal. Tunka-Rex measures air-showers induced by high-energy cosmic rays, in particular, the lateral distribution of the radio pulses. The depth of the air-shower maximum, statistically depends on the mass of the primary particle, is determined from the slope of the lateral distribution function (LDF). Using a model-independent approach, we have studied possible features of the one-dimensional slope method and tried to find improvements for the reconstruction of primary mass. To study the systematic uncertainties given by different primary particles, we have performed simulations using the CONEX and CoREAS software packages of the recently released CORSIKA v7.5 including the modern high-energy hadronic models QGSJet-II.04 and EPOS-LHC. The simulations have shown that the largest systematic uncertainty in the energy deposit is due to the unknown primary particle. Finally, we studied the relation between the polarization and the asymmetry of the LDF.

Metastatic Organotropism: An Intrinsic Property of Breast Cancer Molecular Subtypes.
Wei, Shi; Siegal, Gene P
2017-03-01
It has long been known that some cancers have the propensity to metastasize to certain organs thus creating a nonrandom distribution of sites for distant relapse, a phenomenon known as "metastatic organotropism." Some of these examples include ovary primary to abdominal cavity, prostate primary to bone, and pancreas primary to liver. In contrast, other tumor types, such as mammary and renal cell carcinoma, can relapse in multiple organs although approximately half of advanced breast cancers metastasize to bone. On the other hand gene expression profiling studies have identified various breast cancer classes with prognostic significance. Recent studies have revealed that breast cancer subtypes differ not only in primary tumor characteristics but also in their metastatic behavior. In particular, the luminal tumors are remarkable for their significant bone-seeking phenotype; the HER2 subtype demonstrates a significant liver-homing characteristic; whereas so-called triple-negative breast cancers predispose to lung metastases. These findings suggest that this knowledge could potentially be utilized in the development of effective disease surveillance strategies in the pursuit of precision medicine, thus necessitating further investigation.

The Begraft Peripheral PMCF study is a prospective, non-randomized study, conducted at the vascular departments of 4 hospitals in Belgium. This manuscript reports the findings up to 12-month follow-up time for the total cohort. The primary endpoint of the study is primary patency at 12 months. Primary patency is defined as a target lesion without a hemodynamically significant stenosis on duplex ultrasound (>50%, systolic velocity ratio no greater than 2.4) and without Target Lesion Revascularization (TLR) within 12 months. Between June 2014 and March 2015, 70 patients with TASC II Class A (77.1%), B (14.3%), C (5.7%) or D (2.9%) aortoiliac lesions were included. The mean lesion length was 34.3mm with a mean degree of stenosis of 83.16%. Primary patency rate for the total patient population was 94.4% at 12-month follow-up. Freedom from TLR at 12-month was 96.7%. These results confirm the already existing enthusiasm of the use of covered stents in the aorto-iliac field. Longer follow-up and more complex lesions have to be studies in the upcoming future.

This study explored the role of organizational factors in the ability of Veterans Health Administration (VHA) clinics to implement colocated mental health care in primary care settings (PC-MH). The study used data from the VHA Clinical Practice Organizational Survey collected in 2007 from 225 clinic administrators across the United States. Clinic degree of implementation of PC-MH was the dependent variable, whereas independent variables included policies and procedures, organizational context, and leaders' perceptions of barriers to change. Pearson bivariate correlations and multivariable linear regression were used to test hypotheses. Results show that depression care training for primary care providers and clinics' flexibility and participation were both positively correlated with implementation of PC-MH. However, after accounting for other factors, regressions show that only training primary care providers in depression care was marginally associated with degree of implementation of PC-MH (p = 0.051). Given the importance of this topic for implementing integrated care as part of health care reform, these null findings underscore the need to improve theory and testing of more proximal measures of colocation in future work.

Aim This study explored the partnership between universities and local primary schools to deliver a classroom-based paediatric communication impairment service provided by undergraduate speech pathology students. It aimed to understand how partnerships work to facilitate programme replication. The partners included universities sending students on rural clinical placement, local host academic units and primary schools who worked together to provide paediatric speech and language services in primary schools in three sites in Australia. Rural and remote communities experience poorer health outcomes because of chronic workforce shortages, social disadvantage and high Aboriginality, poor access to services and underfunding. The study was in twofold: qualitative analysis of data from interviews/focus group with the partners in the university and education sectors, and quantitative social network analysis of data from an electronic survey of the partners. Findings Factors supporting partnerships were long-term, work and social relationships, commitment to community, trust and an appetite for risk-taking. We postulate that these characteristics are more likely to exist in rural communities.

Perinatal mortality in caribou from the Porcupine herd, Alaska
Roffe, T.J.
1993-01-01
During the 1989 caribou (Rangifer tarandus) calving season on the Arctic National Wildlife Refuge, Alaska (USA), 61 calf carcasses were examined for cause of death and associated pathology. Dead calves were located by low-level aerial searches with two fixed-wing aircraft and a helicopter over high density calving areas between the Hulahula and Aichilik rivers. Primary diagnoses included emaciation (39%), malnutrition (8%), stillbirth (21%), trauma (16%), other primary causes (7%), and undetermined causes (8%). Twenty calves had contributory renal tubular degeneration. The findings indicate that factors contributing to nutritional deprivation in calves were the major cause of neonatal mortality; however, factors affecting stillbirth, abortion, or the urogenital system may have major effects on neonatal caribou and warrant further investigation.

Leiomyosarcoma (LMS) is a malignant neoplasm composed of cells showing distinct smooth muscle features. Majority of the tumors are located in the retroperitoneum, including the pelvis and the uterus but are rare in the oral and pharyngeal region. Intraorally, they are present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or older individuals. Lesions are usually slow growing and are less than 2 cm in diameter at the time of diagnosis. Here we report the clinico-pathological findings of a case of primary LMS of the maxilla in 63-year-old male patient with an emphasis on the judicious use of ancillary diagnostic modalities to arrive at a definitive diagnosis.

Primary tumors metastasizing to the oral cavity are extremely rare. Lung is one of the most common primary sources of metastases to the tongue. Although the incidence of lung cancer is increasing, tongue metastasis as the initial presentation of the tumor remains uncommon. Due to the rarity of tongue metastasis, little is known about its imaging findings. Herein we report the magnetic resonance imaging and clinical findings of a lingual metastasis, mimicking an abscess, from a primary lung cancer.

Being a young adult with mental illness challenges all aspects of health, including an increased risk for developing lifestyle-related diseases. There is a lack of lifestyle programmes in primary health care that target physical, mental, and social needs for young adults with mental illness. The aim of the present study was to describe the experiences of young adults with mental illness receiving support from a nurse-led lifestyle programme, and how this support was related to their life context, including challenges and coping strategies. Two focus groups and six individual interviews were performed with 13 young adults (16-25 years), and analysed using a qualitative content analysis. The findings showed that the young adults experienced challenges in their daily lives, including psychiatric symptoms, lack of social understanding, and loneliness. The study indicated that the programme could support lifestyle habits with its components of supportive interpersonal relationships, awareness of coping strategies, understanding of health and illness, and cognitive support (e.g. schedules and reminders). However, the programme could not meet everyone's needs for new social relationships or more comprehensive support. Even so, this nurse-led programme provides health information-management strategies that could easily be integrated in a primary health-care setting. © 2017 Australian College of Mental Health Nurses Inc.

Internet safety education for youth: stakeholder perspectives.
Moreno, Megan A; Egan, Katie G; Bare, Kaitlyn; Young, Henry N; Cox, Elizabeth D
2013-06-05
Internet use is nearly ubiquitous among US youth; risks to internet use include cyberbullying, privacy violations and unwanted solicitation. Internet safety education may prevent these negative consequences; however, it is unclear at what age this education should begin and what group is responsible for teaching this topic. Surveys were distributed to key stakeholders in youth safety education including public school teachers, clinicians, parents and adolescents. Surveys assessed age at which internet safety education should begin, as well as experiences teaching and learning internet safety. Surveys of adults assessed willingness to teach internet safety. Finally, participants were asked to identify a group whose primary responsibility it should be to teach internet safety. A total of 356 participants completed the survey (93.4% response rate), including 77 teachers, 111 clinicians, 72 parents and 96 adolescents. Stakeholders felt the optimal mean age to begin teaching internet safety was 7.2 years (SD = 2.5), range 2-15. Internet safety was regularly taught by some teachers (20.8%), few clinicians (2.6%) and many parents (40.3%). The majority of teachers, clinicians and parents were willing to teach internet safety, but all groups surveyed identified parents as having primary responsibility for teaching this topic. Findings suggest agreement among key stakeholders for teaching internet safety at a young age, and for identifying parents as primary teachers of this topic. Clinicians have a unique opportunity to support parents by providing resources, guidance and support.

Conflict on interprofessional primary health care teams--can it be resolved?
Brown, Judith; Lewis, Laura; Ellis, Kathy; Stewart, Moira; Freeman, Thomas R; Kasperski, M Janet
2011-01-01
Increasingly, primary health care teams (PHCTs) depend on the contributions of multiple professionals. However, conflict is inevitable on teams. This article examines PHCTs members' experiences with conflict and responses to conflict. This phenomenological study was conducted using in-depth interviews with 121 participants from 16 PHCTs (10 urban and 6 rural) including a wide range of health care professionals. An iterative analysis process was used to examine the verbatim transcripts. The analysis revealed three main themes: sources of team conflict; barriers to conflict resolution; and strategies for conflict resolution. Sources of team conflict included: role boundary issues; scope of practice; and accountability. Barriers to conflict resolution were: lack of time and workload; people in less powerful positions; lack of recognition or motivation to address conflict; and avoiding confrontation for fear of causing emotional discomfort. Team strategies for conflict resolution included interventions by team leaders and the development of conflict management protocols. Individual strategies included: open and direct communication; a willingness to find solutions; showing respect; and humility. Conflict is inherent in teamwork. However, understanding the potential barriers to conflict resolution can assist PHCTs in developing strategies to resolve conflict in a timely fashion.

White Oak Dam is located in the White Oak Creek watershed which provides the primary surface drainage for Oak Ridge National Laboratory. A stability analysis was made on the dam by Syed Ahmed in January 1994 which included an evaluation of the liquefaction potential of the embankment and foundation. This report evaluates the stability of the dam and includes comments on the report prepared by Ahmed. Slope stability analyses were performed on the dam and included cases for sudden drawdown, steady seepage, partial pool and earthquake. Results of the stability analyses indicate that the dam is stable and failure ofmore » the structure would not occur for the cases considered. The report prepared by Ahmed leads to the same conclusions as stated above. Review of the report finds that it is complete, well documented and conservative in its selection of soil parameters. The evaluation of the liquefaction potential is also complete and this report is in agreement with the findings that the dam and foundation are not susceptible to liquefaction.« less

Purpose To review the reports of subsequent neoplasms (SNs) in the Childhood Cancer Survivor Study (CCSS) cohort that were made through January 1, 2006, and published before July 31, 2008, and to discuss the host-, disease-, and therapy-related risk factors associated with SNs. Patients and Methods SNs were ascertained by survivor self-reports and subsequently confirmed by pathology findings or medical record review. Cumulative incidence of SNs and standardized incidence ratios for second malignant neoplasms (SMNs) were calculated. The impact of host-, disease-, and therapy-related risk factors was evaluated by Poisson regression. Results Among 14,358 cohort members, 730 reported 802 SMNs (excluding nonmelanoma skin cancers). This represents a 2.3-fold increase in the number of SMNs over that reported in the first comprehensive analysis of SMNs in the CCSS cohort, which was done 7 years ago. In addition, 66 cases of meningioma and 1,007 cases of nonmelanoma skin cancer were diagnosed. The 30-year cumulative incidence of SMNs was 9.3% and that of nonmelanoma skin cancer was 6.9%. Risk of SNs remains elevated for more than 20 years of follow-up for all primary childhood cancer diagnoses. In multivariate analyses, risks differ by SN subtype, but include radiotherapy, age at diagnosis, sex, family history of cancer, and primary childhood cancer diagnosis. Female survivors whose primary childhood cancer diagnosis was Hodgkin's lymphoma or sarcoma and who received radiotherapy are at particularly increased risk. Analyses of risk associated with radiotherapy demonstrated different dose-response curves for specific SNs. Conclusion Childhood cancer survivors are at a substantial and increasing risk for SNs, including nonmelanoma skin cancer and meningiomas. Health care professionals should understand the magnitude of these risks to provide individuals with appropriate counseling and follow-up. PMID:19255307

Introduction Incomplete or inconsistent reporting remains a major concern in the biomedical literature. Incomplete or inconsistent reporting may yield the published findings unreliable, irreproducible or sometimes misleading. In this study based on evidence from systematic reviews and surveys that have evaluated the reporting issues in primary biomedical studies, we aim to conduct a scoping review with focuses on (1) the state-of-the-art extent of adherence to the emerging reporting guidelines in primary biomedical research, (2) the inconsistency between protocols or registrations and full reports and (3) the disagreement between abstracts and full-text articles. Methods and analyses We will use a comprehensive search strategy to retrieve all available and eligible systematic reviews and surveys in the literature. We will search the following electronic databases: Web of Science, Excerpta Medica Database (EMBASE), MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Our outcomes are levels of adherence to reporting guidelines, levels of consistency between protocols or registrations and full reports and the agreement between abstracts and full reports, all of which will be expressed as percentages, quality scores or categorised rating (such as high, medium and low). No pooled analyses will be performed quantitatively given the heterogeneity of the included systematic reviews and surveys. Likewise, factors associated with improved completeness and consistency of reporting will be summarised qualitatively. The quality of the included systematic reviews will be evaluated using AMSTAR (a measurement tool to assess systematic reviews). Ethics and dissemination All findings will be published in peer-reviewed journals and relevant conferences. These results may advance our understanding of the extent of incomplete and inconsistent reporting, factors related to improved completeness and consistency of reporting and potential recommendations for various stakeholders in the biomedical community.

Changes to cognition, including memory, following radiation exposure are a concern for cosmic ray exposures to astronauts and in Hadron therapy with proton and heavy ion beams. The purpose of the present work is to develop computational methods to evaluate microscopic energy deposition (ED) in volumes representative of neuron cell structures, including segments of dendrites and spines, using a stochastic track structure model. A challenge for biophysical models of neuronal damage is the large sizes (>100 μm) and variability in volumes of possible dendritic segments and pre-synaptic elements (spines and filopodia). We consider cylindrical and spherical microscopic volumes of varying geometric parameters and aspect ratios from 0.5 to 5 irradiated by protons, and 3He and 12C particles at energies corresponding to a distance of 1 cm to the Bragg peak, which represent particles of interest in Hadron therapy as well as space radiation exposure. We investigate the optimal axis length of dendritic segments to evaluate microscopic ED and hit probabilities along the dendritic branches at a given macroscopic dose. Because of large computation times to analyze ED in volumes of varying sizes, we developed an analytical method to find the mean primary dose in spheres that can guide numerical methods to find the primary dose distribution for cylinders. Considering cylindrical segments of varying aspect ratio at constant volume, we assess the chord length distribution, mean number of hits and ED profiles by primary particles and secondary electrons (δ-rays). For biophysical modeling applications, segments on dendritic branches are proposed to have equal diameters and axes lengths along the varying diameter of a dendritic branch. PMID:28554507

Background External supervision of primary healthcare facilities in low- and middle-income countries often has a managerial main purpose in which the role of support for professional development is unclear. Aim To explore how Rwandan primary healthcare supervisors and providers (supervisees) perceive evaluative and formative functions of external supervision. Design Qualitative, exploratory study. Data Focus group discussions: three with supervisors, three with providers, and one mixed (n = 31). Findings were discussed with individual and groups of supervisors and providers. Results Evaluative activities occupied providers’ understanding of supervision, including checking, correcting, marking and performance-based financing. These were presented as sources of motivation, that in self-determination theory indicate introjected regulation. Supervisors preferred to highlight their role in formative supervision, which may mask their own and providers’ uncontested accounts that systematic performance evaluations predominated supervisors’ work. Providers strongly requested larger focus on formative and supportive functions, voiced as well by most supervisors. Impact of performance evaluation on motivation and professional development is discussed. Conclusion While external supervisors intended to support providers’ professional development, our findings indicate serious problems with this in a context of frequent evaluations and performance marking. Separating the role of supporter and evaluator does not appear as the simple solution. If external supervision is to improve health care services, it is essential that supervisors and health centre managers are competent to support providers in a way that transparently accounts for various performance pressures. This includes delivery of proper formative supervision with useful feedback, maintaining an effective supervisory relationship, as well as ensuring providers are aware of the purpose and content of evaluative and formative supervision functions.

The shortage of liver donations demands the use of suboptimal grafts with steatosis being a frequent finding. Although ≤30% macrovesicular steatosis is considered to be safe the risk for primary non-function (PNF) and outcome after re-transplantation (re-OLT) is unknown. Among 1205 orthotopic liver transplantations performed at our institution the frequency, survival and reason of re-OLT were evaluated. PNF (group A) cases and those with initial transplant function but subsequent need for re-OLT (group B) were analysed. Histopathology and clinical judgement determined the cause of PNF and included an assessment of hepatic steatosis. Additionally, survival of fatty liver allografts (group C) not requiring re-OLT was considered in Kaplan-Meier and multivariate regression analysis. A total of 77 high urgency re-OLTs were identified and included 39 PNF cases. Nearly 70% of PNF cases were due to primary fatty liver allografts. The 3-month in-hospital mortality for PNF cases after re-OLT was 46% and the mean survival after re-OLT was 0.5 years as compared to 5.2 and 5.1 years for group B, C, respectively, (P<.008). In multivariate Cox regression analysis only hepatic steatosis was associated with an inferior survival (HR 4.272, P=.002). The MELD score, donor BMI, age, cold ischaemic time, ICU stay, serum sodium and transaminases did not influence overall survival. Our study highlights fatty liver allografts to be a major cause for PNF with excessive mortality after re-transplantation. The findings demand the development of new methods to predict risk for PNF of fatty liver allografts. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Aim To investigate the implementation and initial impact of the Physician Integrated Network (PIN) mental health indicators, which are specific to screening and managing follow-up for depression, in three primary care practices with Shared Mental Health Care in Manitoba. Manitoba Health undertook a primary care renewal initiative in 2006 called the PIN, which included the development of mental health indicators specific to screening and managing follow-up for depression. These indicators were implemented in three PIN group practice sites in Manitoba, which are also part of Shared Mental Health Care. The design was a non-experimental longitudinal design. A formative evaluation investigated the implementation and initial impact of the mental health indicators using mixed methods (document review, survey, and interview). Quantitative data was explored using descriptive and comparative statistics and a content and theme analysis of the qualitative interviews was conducted. Survey responses were received from 32 out of 36 physicians from the three sites. Interviews were conducted with 15 providers. Findings This evaluation illustrated providers' perceived attitudes, knowledge, skills, and behaviours related to recognizing and treating depression and expanded our understanding of primary care processes related to managing depression related to the implementation of a new initiative. Depression is viewed as an important problem in primary care practice that is time consuming to diagnose, manage and treat and requires further investigation. Implementation of the PIN mental health indicators was variable across sites and providers. There was an increase in use of the indicators across time and a general sentiment that benefits of screening outweigh the costs; however, the benefit of screening for depression remains unclear. Consistent with current guidelines, a question the findings of this evaluation suggests is whether there are more effective ways of having an impact on depression within primary care than screening.

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.

Background The diagnosis of COPD is not always consistent with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy in daily clinical practice, especially in primary care. This study aimed to estimate the overall COPD prevalence and severity, to identify differences between newly and previously diagnosed patients, and to evaluate the potential COPD overtreatment in a smoking population attending a primary care spirometry surveillance program. Methods A study was conducted in 10 primary health care centers of Central Greece during a 7-month period. Eligible participants were aged ≥40 years and were either current smokers or exsmokers. Results A total of 186 subjects were included (68% males, mean age 62.3±12.6 years, mean life-time tobacco exposure 50 pack-years). COPD prevalence was 17.8%, identified to be higher in elderly males. Forty-two percent of the COPD group were newly diagnosed patients, who were of younger age, current smokers, presented with less dyspnea and better health status, and mainly appeared with mild-to-moderate disease. Interestingly, 61.4% of non-COPD and 85.7% of newly diagnosed COPD individuals had been using inhaled medication under primary care provider’s prescription without ever undergoing spirometry or further evaluation by a pulmonologist; thus, the phenomena of COPD overdiagnosis and missed diagnosis came into the spotlight. Moreover, only 26.3% of known COPD patients were properly medicated according to GOLD guidelines, while half of them were inappropriately treated with triple inhaled therapy. Conclusion We reported a significant prevalence of COPD in smoking population attending this spirometry program. A remarkable proportion of COPD patients were undiagnosed and made case finding worthwhile. Underutilization of spirometry in the diagnosis and management of COPD as well as general practitioners’ nonadherence to the GOLD treatment guidelines was confirmed by our data. These findings highlight the need for a major overhaul and culture change in primary care settings of Central Greece. PMID:29440886

Background Large colon impactions are a common cause of colic in the horse. There are no scientific reports on the clinical presentation, diagnostic tests and treatments used in first opinion practice for large colon impaction cases. The aim of this study was to describe the presentation, diagnostic approach and treatment at the primary assessment of horses with large colon impactions. Methods Data were collected prospectively from veterinary practitioners on the primary assessment of equine colic cases over a 12 month period. Inclusion criteria were a diagnosis of primary large colon impaction and positive findings on rectal examination. Data recorded for each case included history, signalment, clinical and diagnostic findings, treatment on primary assessment and final case outcome. Case outcomes were categorised into three groups: simple medical (resolved with single treatment), complicated medical (resolved with multiple medical treatments) and critical (required surgery, were euthanased or died). Univariable analysis using one-way ANOVA and Tukey’s post-hoc test, Kruskal Wallis with Dunn’s post-hoc test and Chi squared analysis were used to compare between different outcome categories. Results 1032 colic cases were submitted by veterinary practitioners: 120 cases met the inclusion criteria for large colon impaction. Fifty three percent of cases were categorised as simple medical, 36.6% as complicated medical, and 9.2% as critical. Most cases (42.1%) occurred during the winter. Fifty nine percent of horses had had a recent change in management, 43% of horses were not ridden, and 12.5% had a recent / current musculoskeletal injury. Mean heart rate was 43bpm (range 26-88) and most cases showed mild signs of pain (67.5%) and reduced gut sounds (76%). Heart rate was significantly increased and gut sounds significantly decreased in critical compared to simple medical cases (p<0.05). Fifty different treatment combinations were used, with NSAIDs (93%) and oral fluids (71%) being administered most often. Conclusions Large colon impactions typically presented with mild signs of colic; heart rate and gut sounds were the most useful parameters to distinguish between simple and critical cases at the primary assessment. The findings of seasonal incidence and associated management factors are consistent with other studies. Veterinary practitioners currently use a wide range of different treatment combinations for large colon impactions. PMID:25238179

Osteoarthritis is a highly prevalent and disabling condition. Primary care management of osteoarthritis is generally suboptimal despite evidence for several modestly effective interventions and the availability of high-quality clinical practice guidelines. This report describes a planned study to synthesise the views of primary care clinicians on the barriers and enablers to following recommended management of osteoarthritis, with the aim of providing new interpretations that may facilitate the uptake of recommended treatments, and in turn improve patient care. A systematic review and meta-synthesis of qualitative studies. 5 databases will be searched using key search terms for qualitative research, evidence-based practice, clinical practice guidelines, osteoarthritis, beliefs, perceptions, barriers, enablers and adherence. A priori inclusion/exclusion criteria include availability of data from primary care clinicians, reports on views regarding management of osteoarthritis, and studies using qualitative methods for both data collection and analysis. At least 2 independent reviewers will identify eligible reports, conduct a critical appraisal of study conduct, extract data and synthesise reported findings and interpretations. Synthesis will follow thematic analysis within a grounded theory framework of inductive coding and iterative theme identification. The reviewers plus co-authors will contribute to the meta-synthesis to find new themes and theories. The Confidence in the Evidence from Reviews of Qualitative research (CERQual) approach will be used to determine a confidence profile of each finding from the meta-synthesis. The protocol has been registered on PROSPERO and is reported using the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) guidelines. Ethical approval is not required. The systematic review will be published in a peer-reviewed journal. The results will help to inform policy and practice and assist in the optimisation of management for people with osteoarthritis. CRD42015027543. Published by the BMJ Publishing Group Limited.

Memetic algorithms for de novo motif-finding in biomedical sequences.
Bi, Chengpeng
2012-09-01
The objectives of this study are to design and implement a new memetic algorithm for de novo motif discovery, which is then applied to detect important signals hidden in various biomedical molecular sequences. In this paper, memetic algorithms are developed and tested in de novo motif-finding problems. Several strategies in the algorithm design are employed that are to not only efficiently explore the multiple sequence local alignment space, but also effectively uncover the molecular signals. As a result, there are a number of key features in the implementation of the memetic motif-finding algorithm (MaMotif), including a chromosome replacement operator, a chromosome alteration-aware local search operator, a truncated local search strategy, and a stochastic operation of local search imposed on individual learning. To test the new algorithm, we compare MaMotif with a few of other similar algorithms using simulated and experimental data including genomic DNA, primary microRNA sequences (let-7 family), and transmembrane protein sequences. The new memetic motif-finding algorithm is successfully implemented in C++, and exhaustively tested with various simulated and real biological sequences. In the simulation, it shows that MaMotif is the most time-efficient algorithm compared with others, that is, it runs 2 times faster than the expectation maximization (EM) method and 16 times faster than the genetic algorithm-based EM hybrid. In both simulated and experimental testing, results show that the new algorithm is compared favorably or superior to other algorithms. Notably, MaMotif is able to successfully discover the transcription factors' binding sites in the chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq) data, correctly uncover the RNA splicing signals in gene expression, and precisely find the highly conserved helix motif in the transmembrane protein sequences, as well as rightly detect the palindromic segments in the primary microRNA sequences. The memetic motif-finding algorithm is effectively designed and implemented, and its applications demonstrate it is not only time-efficient, but also exhibits excellent performance while compared with other popular algorithms.

To carry out a systematic review of recent research into the effects of workplace design, comparing individual with shared workspaces, on the health of employees. The research question was "Does workplace design (specifically individual offices compared with shared workspaces) affect the health of workers?" A literature search limited to articles published between 2000 and 2017 was undertaken. A systematic review was carried out, and the findings of the reviewed studies grouped into themes according to the primary outcomes measured in the studies. The literature search identified 15 relevant studies addressing health effects of shared or open-plan offices compared with individual offices. Our systematic review found that, compared with individual offices, shared or open-plan office space is not beneficial to employees' health, with consistent findings of deleterious effects on staff health, wellbeing and productivity. Our findings are also consistent with those of earlier reviews. These findings have public health implications for the New Zealand workforce. Decisions about workplace design should include weighing the short-term financial benefits of open-plan or shared workspaces against the significant harms, including increased sickness absence, lower job satisfaction and productivity, and possible threats to recruitment and retention of staff.

Characteristics of Qualitative Descriptive Studies: A Systematic Review
Kim, Hyejin; Sefcik, Justine S.; Bradway, Christine
2016-01-01
Qualitative description (QD) is a term that is widely used to describe qualitative studies of health care and nursing-related phenomena. However, limited discussions regarding QD are found in the existing literature. In this systematic review, we identified characteristics of methods and findings reported in research articles published in 2014 whose authors identified the work as QD. After searching and screening, data were extracted from the sample of 55 QD articles and examined to characterize research objectives, design justification, theoretical/philosophical frameworks, sampling and sample size, data collection and sources, data analysis, and presentation of findings. In this review, three primary findings were identified. First, despite inconsistencies, most articles included characteristics consistent with limited, available QD definitions and descriptions. Next, flexibility or variability of methods was common and desirable for obtaining rich data and achieving understanding of a phenomenon. Finally, justification for how a QD approach was chosen and why it would be an appropriate fit for a particular study was limited in the sample and, therefore, in need of increased attention. Based on these findings, recommendations include encouragement to researchers to provide as many details as possible regarding the methods of their QD study so that readers can determine whether the methods used were reasonable and effective in producing useful findings.

Driessen, Geert W. J. M.
2001-11-01
Bourdieu's cultural capital thesis is an attempt to explain how social class influences the transmission of educational inequality. In this article, the question of the extent to which various forms of capital also apply to ethnic minorities stands central. On the basis of Dutch and American research findings, a model is formulated and empirically tested with the aid of data from the Dutch Primary Education cohort study. Students from four ethnic groups are included: Dutch, Surinamese, Turkish, and Moroccan. The main variables are language and math test scores, socio-economic milieu, and a number of capital indicators, including financial resources, linguistic resources, parental reading behavior, and educational resources within the family. The results show no mediating effect of resources within the various ethnic groups. The findings also suggest that in research and practice it is relevant to not treat ethnic groups as one homogenous group, but to differentiate between the various groups.

Trauma-induced dissociative amnesia in World War I combat soldiers. II. Treatment dimensions.
Brown, P; van der Hart, O; Graafland, M
1999-06-01
This is the second part of a study of posttraumatic amnesia in World War I (WW I) soldiers. It moves beyond diagnostic validation of posttraumatic amnesia (PTA), to examine treatment findings, and relates these to contemporary treatment of dissociative amnesia, including treatment of victims of civilian trauma (e.g. childhood sexual abuse). Key WW I studies are surveyed which focus on the treatment of PTA and traumatic memories. The dissociation-integration and repression-abreaction models are contrasted. Descriptive evidence is cited in support of preferring Myers' and McDougalls' dissociation-integration treatment approach over Brown's repression-abreaction model. Therapeutic findings in this paper complement diagnostic data from the first report. Although effective treatment includes elements of both the dissociative-integrative and abreactive treatment approaches, cognitive integration of dissociated traumatic memories and personality functions is primary, while emotional release is secondary.

Objective This qualitative study examined applicability and need for tailoring of an evidence-based engagement intervention, combined with Trauma-focused Cognitive Behavioral Therapy, for foster parents. Method Qualitative methods were used, including individual interviews with participating foster parents (N = 7), review of interview findings with an independent group of foster parents (N = 5), and review of the combined foster parent findings by child welfare caseworkers (N = 5), an important stakeholder group. Results The engagement intervention, with its primary focus on perceptual barriers (e.g., past experiences with mental health), was relevant for the foster care population. However, the study identified areas for tailoring to better recognize and address the unique needs and situation of foster parents as substitute caregivers. Conclusions Perceptually-focused engagement interventions may have broad applicability to a range of populations, including foster parents, with the potential for improving caregiver participation in children’s mental health services.

Differential diagnosis of food protein-induced enterocolitis syndrome
Fiocchi, Alessandro; Claps, Alessia; Dahdah, Lamia; Brindisi, Giulia; Dionisi-Vici, Carlo; Martelli, Alberto
2014-01-01
Purpose of review To assess all the possible differential diagnosis of food protein-induced enterocolitis syndrome (FPIES), both in acute and chronic presentation, reviewing the data reported in published studies. Recent findings There is an increase of reported cases of FPIES in recent years. As the disease presents with nonspecific symptoms, it can be misunderstood in many ways. The differential diagnosis includes, in acute presentations, the following: sepsis, other infectious diseases, acute gastrointestinal episodes, surgical emergencies, food allergies. In its chronic forms, FPIES may mimic malabsorption syndromes, metabolic disorders, primary immunodeficiencies, neurological conditions, coagulation defects, and other types of non-IgE-mediated food allergy. Summary A thorough clinical evaluation, including symptoms, signs, and laboratory findings, is necessary to lead the clinicians toward the diagnosis of FPIES. The major reason for delayed diagnosis appears to be the lack of knowledge of the disease. PMID:24739227

Functional abdominal pain in childhood: Background studies and recent research trends
Levy, Rona L; van Tilburg, Miranda AL
2012-01-01
The present review summarizes many of the major research trends investigated in the past five years regarding pediatric functional abdominal pain, and also summarizes the primary related findings from the authors’ research program. Specific areas discussed based on work within the authors’ group include familial illness patterns, genetics, traits, and mechanisms or processes related to abdominal pain. Topics covered from research published in the past five years include prevalence and cost, longitudinal follow-up, overlap with other disorders, etiology and mechanisms behind functional abdominal pain and treatment studies. It is hoped that findings from this work in abdominal pain will be interpreted as a framework for understanding the processes by which other pain phenomena and, more broadly, reactions to any physical state, can be developed and maintained in children. The present article concludes with recommendations for clinical practice and research. PMID:23248815

Primary care patient-centered medical homes (PCMHs) are an effective healthcare delivery model. Evidence regarding the most effective payment models for increased coordination efforts is sparse. This protocol paper describes the evaluation of an Alternative Payment Methodology (APM) implemented in a subset of Oregon community health centers (CHCs), using a prospective matched observational design. The APM is a primary care payment reform intervention that changed Oregon’s Medicaid payment for several CHCs from fee-for-service reimbursement to a per-member-per-month capitated payment. We will implement a difference-in-difference analytic approach to evaluate pre-post APM changes between intervention and control groups, including: 1) clinic-level outcomes, 2) patient-level clinical outcomes, and 3) patient-level econometric outcomes. Findings from the project will be of national significance, as there is a need for evidence regarding how novel payment methods might enhance PCMH capabilities and support their capacity to produce better quality and outcomes. If this capitated payment method is proven effective, study findings will inform dissemination of similar APMs nationwide. PMID:27836506

Microprocessor depends on hemin to recognize the apical loop of primary microRNA
Park, Joha; Dang, Thi Lieu; Choi, Yeon-Gil; Kim, V Narry
2018-01-01
Abstract Microprocessor, which consists of a ribonuclease III DROSHA and its cofactor DGCR8, initiates microRNA (miRNA) maturation by cleaving primary miRNA transcripts (pri-miRNAs). We recently demonstrated that the DGCR8 dimer recognizes the apical elements of pri-miRNAs, including the UGU motif, to accurately locate and orient Microprocessor on pri-miRNAs. However, the mechanism underlying the selective RNA binding remains unknown. In this study, we find that hemin, a ferric ion-containing porphyrin, enhances the specific interaction between the apical UGU motif and the DGCR8 dimer, allowing Microprocessor to achieve high efficiency and fidelity of pri-miRNA processing in vitro. Furthermore, by generating a DGCR8 mutant cell line and carrying out rescue experiments, we discover that hemin preferentially stimulates the expression of miRNAs possessing the UGU motif, thereby conferring differential regulation of miRNA maturation. Our findings reveal the molecular action mechanism of hemin in pri-miRNA processing and establish a novel function of hemin in inducing specific RNA-protein interaction. PMID:29750274

We recently demonstrated that the DGCR8 dimer recognizes the apical elements of pri-miRNAs, including the UGU motif, to accurately locate and orient Microprocessor on pri-miRNAs. However, the mechanism underlying the selective RNA binding remains unknown. In this study, we find that hemin, a ferric ion-containing porphyrin, enhances the specific interaction between the apical UGU motif and the DGCR8 dimer, allowing Microprocessor to achieve high efficiency and fidelity of pri-miRNA processing in vitro. Furthermore, by generating a DGCR8 mutant cell line and carrying out rescue experiments, we discover that hemin preferentially stimulates the expression of miRNAs possessing the UGU motif, thereby conferring differential regulation of miRNA maturation. Our findings reveal the molecular action mechanism of hemin in pri-miRNA processing and establish a novel function of hemin in inducing specific RNA-protein interaction.

While studies of home-based care delivered by teams led by primary care providers have shown cost savings, little is known about outcomes when practice-extender teams-that is, teams led by registered nurses or lay health workers-provide home visits with similar components (for example, care coordination and education). We evaluated findings from five models funded by Health Care Innovation Awards of the Centers for Medicare and Medicaid Services. Each model used a mix of different components to strengthen connections to primary care among fee-for-service Medicare beneficiaries with multiple chronic conditions; these connections included practice-extender home visits. Two models achieved significant reductions in Medicare expenditures, and three models reduced utilization in the form of emergency department visits, hospitalizations, or both for beneficiaries relative to comparators. These findings present a strong case for the potential value of home visits by practice-extender teams to reduce Medicare expenditures and service use in a particularly vulnerable and costly segment of the Medicare population.

The role of the alliance in predicting treatment outcome is robust and long established. However, much less attention has been paid to mechanisms of change, including moderators, particularly for youth. This study examined the moderating role of pretreatment adolescent-caregiver attachment and its impact on the working alliance-treatment outcome relationship. One hundred adolescents and young adults with primary substance dependence disorders were treated at a residential facility, with a cognitive-behavioral emphasis. The working alliance and clinical symptoms were measured at regular intervals throughout treatment. A moderator hypothesis was tested using a path analytic approach. Findings suggested that attachment to the primary caregiver moderated the impact of the working alliance on treatment outcome, such that for youth with the poorest attachment history, working alliance had a stronger relationship with outcome. Conversely, for those with the strongest attachment histories, alliance was not a significant predictor of symptom reduction. This finding may help elucidate alliance-related mechanisms of change, lending support for theories of corrective emotional experience as one function of the working alliance in youth psychotherapy.

This article describes findings from ongoing research and analysis of current literature in addition to discussions with leaders in the field, communications with lawyers and administrators of advocacy and government agencies pertaining to integrated primary care (IPC). Standards of care are established based on a myriad of factors, including professional codes of ethics, case law, state and federal laws, professional standards, existing best practices, current professional guidelines, administrative rules and regulations, and licensing board regulations. Regulations may differ for behavioral health and medical providers, posing challenges in IPC settings. This article provides a review of these regulations, particularly 42CFR Part 2, a federal law governing confidentiality for substance abuse programs, Health Insurance Portability and Accountability Act (HIPAA), and state laws relevant to patient care in IPC settings. On the basis of findings from the study, the authors make recommendations related to patient care practices concerning informed consent and release of information procedures, treatment and warm hand-off protocols, documentation and electronic record keeping, agreements with other providers, and billing.

Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare but pathologically distinct breast tumor. There have been some case reports on primary MCA of the breast; however, they have all focused on pathologic findings. Here, we report the radiologic findings of two cases of MCA along with a review of the literature. Breast MCA shows a circumscribed mass with some calcifications on mammography, an intracystic solid mass without increased vascularity or a vascular stalk on ultrasound, and a heterogeneously enhancing mass within a rim-enhancing cyst with intermediate signal intensity on T2-weighted magnetic resonance imaging. These radiologic findings and the presence of mucin in the percutaneous biopsy specimen should suggest the possibility of MCA in the differential diagnosis of a breast tumor. PMID:27721884

Meaning in Life: A conceptual model for disaster nursing practice.
Noviana, Uki; Miyazaki, Misako; Ishimaru, Mina
2016-04-01
This study aimed to develop a conceptual model for understanding meaning in life (MIL) using respondents' quotations in the primary qualitative studies. The primary studies were selected from the PsycINFO, PsycARTICLES and CINAHL databases using keywords 'meaning in life', 'meaning of life', 'purpose in life' and 'will to meaning'. Respondents' quotations in the primary studies were analysed interpretatively to identify MIL from the respondents' perspectives. The data were synthesized to integrate findings from 10 selected primary studies. The findings identified (i) six sources of MIL (e.g. having a significant others, having new experiences and performing spiritual activities); (ii) eight components of MIL (e.g. focusing on self, connecting to others, contributing to others and having a sense of direction and purpose); and (iii) the emotional outcomes of having MIL: happiness, satisfaction and joy. Through a discussion of the findings, a conceptual model of MIL emerged. © 2016 John Wiley & Sons Australia, Ltd.

Objective. The objective was to evaluate the capacity of primary care (PC) facilities to implement basic interventions for prevention and management of major noncommunicable diseases (NCDs), including cardiovascular diseases and diabetes. Methods. A cross-sectional survey was done in eight low- and middle-income countries (Benin, Bhutan, Eritrea, Sri Lanka, Sudan, Suriname, Syria, and Vietnam) in 90 PC facilities randomly selected. The survey included questions on the availability of human resources, equipment, infrastructure, medicines, utilization of services, financing, medical information, and referral systems. Results and Conclusions. Major deficits were identified in health financing, access to basic technologies and medicines, medical information systems, and the health workforce. The study has provided the foundation for strengthening PC to address noncommunicable diseases. There are important implications of the findings of this study for all low- and middle-income countries as capacity of PC is fundamental for equitable prevention and control of NCDs. PMID:23251789

Cell senescence is a permanent growth arrest following extended proliferation. Cultured cancer cells including metastatic melanoma cells often appear immortal (proliferate indefinitely), while uncultured benign nevi (moles) show senescence markers. Here, with new explantation methods, we investigated which classes of primary pigmented lesions are typically immortal. Nevi yielded a few proliferating cells, consistent with most nevus cells being senescent. No nevus culture (0/28) appeared immortal. Some thin and thick melanoma cultures proved immortal under these conditions, but surprisingly few (4/37). All arrested cultures displayed three senescence markers in some cells: β-galactosidase, nuclear p16, and heterochromatic foci/aggregates. However, melanoma cultures also showed features of telomeric crisis (arrest because of ultrashort telomeres). Moreover, crisis markers including anaphase bridges were frequent in uncultured vertical growth-phase (VGP) melanomas. Conversely, all immortal melanoma cultures expressed telomerase reverse transcriptase and telomerase, showing aneuploidy. The findings suggest that primary melanomas are typically precrisis, with immortalization/telomere maintenance as a late event. PMID:21418545

Social anxiety disorder (SAD) in children is often comorbid with generalized anxiety disorder (GAD). We investigated whether worry, intolerance of uncertainty, beliefs about worry, negative problem orientation and cognitive avoidance, that are typically associated with GAD, are present in children with SAD. Participants included 60 children (8-12 years), matched on age and gender. Groups included children: with primary GAD and without SAD (GAD); with primary SAD and without GAD (SAD); and without an anxiety disorder (NAD). GAD and SAD groups scored significantly higher than the NAD group on worry, intolerance of uncertainty, negative beliefs about worry and negative problem orientation, however, they did not score differently from each other. Only the GAD group scored significantly higher than the NAD group on cognitive avoidance. These findings further understanding of the structure of SAD and suggest that the high comorbidity between SAD and GAD may be due to similar underlying processes within the disorders.

To determine whether neuropsychiatric symptoms (NPSs) are adequately considered in clinical research on Alzheimer's disease (AD). Systematic review. Randomized controlled trials (RCTs) recruiting individuals with AD and published during the last 10 years in 16 major general medicine, neurology, psychiatry, and geriatric psychiatry journals and RCTs registered on clinicaltrials.gov and currently enrolling individuals with AD. Individuals with AD. Outcome measures adopted by the included studies. Only 21.4% of the included studies identified through the bibliographic searches had measures of NPSs as a primary outcome. Only 17.7% of the studies retrieved on clinicaltrials.gov made a specific effort to test the effect of pharmacological or nonpharmacological interventions on NPSs. These findings show how rarely previous and current research on AD has considered NPSs as primary research targets. Although these symptoms are widely recognized as the most-stressful and -challenging manifestations of dementia, they are addressed much less often than other research targets. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

This critical review evaluates the existing primary research literature to identify experienced registered nurses' attitudes, views and expectations of graduate nurses which may create a barrier for optimal graduate nurse performance. Relevant primary studies were identified by searching online databases using a wide variety of appropriate keyword combinations. Online databases including Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, PsycINFO and Google Scholar were comprehensively searched for relevant research. The selected studies were subjected to a rigorous critical appraisal to evaluate the studies and to determine if the findings were applicable to practice. A manual method of thematic analysis was conducted to highlight explicit and implicit themes from the reviewed studies. Themes were grouped and continually reduced until only essential themes remain. Themes and subthemes emerged which were then compared and contrasted to analyse results. The four major themes identified include nursing skills, inadequate preparation during academic program, attitudes and ward culture and concerns with confidence. Subthemes were identified within these categories. Findings indicate experienced registered nurses discussed themes including 'nursing skills', 'inadequate preparation during academic program', 'attitudes and ward culture' and 'concerns with confidence'. Concerns were raised including the value of traditional training versus tertiary education programs, coping with unprofessional behaviour and inadequate preparation for practice. Further research is required to fully address management of the theory-practice gap, as well as the attitudes of experienced registered nurses educated in traditional programs versus those in tertiary education programs. Nurse managers should be aware of the possible occurrence of unprofessional behaviour, and increased workplace training regarding lateral violence would assist in raising awareness regarding negative and unacceptable behaviour.

Concern has been expressed about the applicability of the findings of the International Subarachnoid Aneurysm Trial (ISAT) with respect to the relative effects on outcome of coiling and clipping. It has been suggested that the findings of the National Study of Subarachnoid Haemorrhage may have greater relevance for neurosurgical practice. The objective of this paper was to interpret the findings of these two studies in the context of differences in their study populations, design, execution and analysis. Because of differences in design and analysis, the findings of the two studies are not directly comparable. The ISAT analysed all randomized patients by intention-to-treat, including some who did not undergo a repair, and obtained the primary outcome for 99% of participants. The National Study only analysed participants who underwent clipping or coiling, according to the method of repair, and obtained the primary outcome for 91% of participants. Time to repair was also considered differently in the two studies. The comparison between coiling and clipping was susceptible to confounding in the National Study, but not in the ISAT. The two study populations differed to some extent, but inspection of these differences does not support the view that coiling was applied inappropriately in the National Study. Therefore, there are many reasons why the two studies estimated different sizes of effect. The possibility that there were real, systematic differences in practice between the ISAT and the National Study cannot be ruled out, but such explanations must be seen in the context of other explanations relating to chance, differences in design or analysis, or confounding.

Locoregional spread of cutaneous melanoma: sonography findings.
Catalano, Orlando; Caracò, Corrado; Mozzillo, Nicola; Siani, Alfredo
2010-03-01
This article reviews various aspects of locoregional spread of malignant cutaneous melanoma, as imaged with gray-scale sonography and Doppler techniques. The scenarios illustrated include disease staging (primary melanoma, satellite metastasis, in-transit metastasis, and lymphadenopathies), sentinel lymph node biopsy procedure, patient follow-up, recurrence detection, cutaneous metastasis, and sonographically guided intervention. High-resolution sonography allows recognition of small, clinically-occult melanomatous foci. It plays a major role in locoregional staging and follow-up of patients with cutaneous melanoma.

To qualitatively examine the perceptions of young fathers toward issues related to early childbearing. Focus groups were held with male partners of adolescent females who had become pregnant while participating in an HIV-prevention trial. Primary domains that emerged included young male's desire for pregnancy, their attitudes toward father/child involvement, and their perceived social support as young fathers. Findings may help in developing gender-appropriate interventions to delay early childbearing and prevent HIV/STD transmission.

There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths' smoking behavior. Understanding these processes of influence is key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents' use of tobacco, in some cases promoting use, and in other cases deterring it. This review also suggests that peer influences on smoking are more subtle than commonly thought and need to be examined more carefully, including consideration of larger social contexts, e.g. the family, neighborhood, and media. Recommendations for future investigations are made, as well as suggestions for specific methodological approaches that offer promise for advancing our knowledge of the contribution of peers on adolescent tobacco use.

Secondary Dystonia-Clinical Clues and Syndromic Associations
Schneider, Susanne A; Bhatia, Kailash P
2009-01-01
Background: Dystonia is a hyperkinetic movement disorder defined by involuntary sustained muscle spasms and unusual postures. Etiologically, dystonic syndromes can be broadly divided into primary and secondary forms, dystonia-plus syndromes and heredodegenerative forms. In particular, diagnosis of secondary dystonic syndromes can be challenging in view of the variety of causes. Purpose: The purpose of this article is to highlight some clinical clues and syndromic associations as well as investigational findings which may be helpful in the approach to a patient with suspected secondary dystonia. Methods: We outline characteristic clinical and neuroimaging findings which may be directive in the diagnostic process of dystonia patients and facilitate making the correct diagnosis, thus allowing initiating the best treatment. Results: Secondary causes of dystonia include, among others, strategic brain lesions of various origins, metabolic disease, neurodegenerative conditions, and previous exposure to drugs or toxins. Presence of clinical signs including prominent oromandibular involvement, eye movement disorders, retinitis pigmentosa, deafness, peripheral neuropathy, parkinsonism or progressive dementia should alert the clinician to consider a secondary cause. Strategic lesions within the basal ganglia, but also within the brainstem, cerebellum or cortical areas may underlie dystonia and should thus be excluded. Conclusions: When thorough clinical examination reveals features atypical of primary dystonia, syndromic associations may help the clinician to narrow down the list of differential diagnosis. Directive investigations like neuroimaging may confirm the clinical suspicion. PMID:24868358

Aims The purpose of this qualitative evaluation was to explore the experience of implementing routine telemonitoring (TM) in real-world primary care settings from the perspective of those delivering the intervention; namely the TM staff, and report on lessons learned that could inform future projects of this type. Routine TM for high-risk patients within primary care practices may help improve chronic disease control and reduce complications, including unnecessary hospital admissions. However, little is known about how to integrate routine TM in busy primary care practices. A TM pilot for diabetic patients was attempted in six primary care practices as part of the Beacon Community in Western New York. Semi-structured interviews were conducted with representatives of three TM agencies (n=8) participating in the pilot. Interviews were conducted over the phone or in person and lasted ~30 min. Interviews were audio-taped and transcribed. Analysis was conducted using immersion-crystallization to identify themes. Findings TM staff revealed several themes related to the experience of delivering TM in real-world primary care: (1) the nurse-patient relationship is central to a successful TM experience, (2) TM is a useful tool for understanding socio-economic context and its impact on patients' health, (3) TM staff anecdotally report important potential impacts on patient health, and (4) integrating TM into primary care practices needs to be planned carefully. This qualitative study identified challenges and unexpected benefits that might inform future efforts. Communication and integration between the TM agency and the practice, including the designation of a point person within the office to coordinate TM and help address the broader contextual needs of patients, are important considerations for future implementation. The role of the TM nurse in developing trust with patients and uncovering the social and economic context within which patients manage their diabetes was an unexpected benefit.

Integrating behavioral health and primary care is beneficial to patients and health systems. However, for integration to be widely adopted, studies demonstrating its benefits in community practices are needed. The objective of this study was to evaluate effect of integrated care, adapted to local contexts, on depression severity and patients' experience of care. This study used a convergent mixed-methods design, merging findings from a quasi-experimental study with patient interviews conducted as part of Advancing Care Together, a community demonstration project that created an innovation incubator for practices implementing evidence-based integration strategies. The study included 475 patients with a 9-item Patient Health Questionnaire (PHQ-9) score ≥10 at baseline, from 5 practices. Statistically significant reductions in mean PHQ-9 scores were observed in all practices, ranging from 2.72 to 6.46 points. Clinically, 50% of patients had a ≥5-point reduction in PHQ-9 score and 32% had a ≥50% reduction. This finding was corroborated by patient interviews that demonstrated positive experiences with behavioral health clinicians and acquiring new skills to cope with adverse situations at work and home. Integrating behavioral health and primary care, when adapted to fit into community practices, reduced depression severity and enhanced patients' experience of care. Integration is a worthwhile investment; clinical leaders, policymakers, and payers should support integration in their communities. © Copyright 2017 by the American Board of Family Medicine.

A salutogenic approach to prevention of metabolic syndrome: a mixed methods population study.
Miettola, Juhani; Viljanen, Anna Maria
2014-12-01
To find a salutogenic approach for prevention of metabolic syndrome in primary care practice. An explanatory sequential mixed-methods procedure was used to find salutogenic approaches for lifestyle change by assessing individual need, potential, and personal motivation. Data from a population health survey and interviews that focused on a sense of coherence were analysed. Altogether 480 Finnish subjects participated in a population health survey, and 43 of them were interviewed. The 43 interviewees' data were included in the final analysis. With the health survey participants' liability for MetS was assessed, and the objective need for lifestyle intervention was determined. Through the focused interviews potential and personal motivation for lifestyle modification were explored. Finally the data of the 43 interviewed subjects were merged. Four possible lifestyle intervention approaches were identified for specific intervention. First, subjects with a strong sense of coherence only need encouragement to maintain a healthy lifestyle; second, professional support was found important for subjects with gaps in health awareness to improve health understanding; third, strengthening of social support for lifestyle change is necessary for subjects with various practical constraints in their everyday life; and fourth, strengthening of stress adaptation is important for subjects with redundant concerns about their health. Salutogenic client-centred lifestyle modification approaches should be part of primary care practice. Further, a cross-disciplinary approach is needed in primary care research and practice to combat the exploding lifestyle illnesses.

To assess and synthesize the published evidence on risk factors of overweight and obesity in childhood and adolescence in South Asia. A systematically conducted narrative review. A systematic review was conducted of all primary studies published between January 1990 and June 2013 from India, Pakistan, Nepal, Bangladesh, Sri Lanka, Bhutan, and Maldives located through the following data bases: PubMed, PubMed central, EMBASE, MEDLINE, BioMed central, Directory of Open Access Journals (DOAJ) and electronic libraries of the authors' institutions. Data extraction and quality appraisal of included studies was done independently by two authors and findings were synthesized in a narrative manner as meta-analysis was found to be inappropriate due to heterogeneity of the included studies. Eleven primary studies were included in the final review, all of which were conducted in school settings in India, Pakistan and Bangladesh. Prevalence of overweight and obesity showed wide variations in the included studies. The key individual risk factors with statistically significant associations to overweight and obesity included: lack of physical activities reported in six studies; prolonged TV watching/playing computer games reported in four studies; frequent consumption of fast food/junk food reported in four studies; and frequent consumption of calorie dense food items reported in two studies. Family level risk factors included higher socioeconomic status reported in four studies and family history of obesity reported in three studies. This review provides evidence of key contributors to the increasing burden of obesity and overweight among children and adolescents in South Asia, and demonstrates the nutritional transition that characterizes other developing countries and regions around the world. The findings have implications for policy, practice and the development of interventions at various levels to promote healthy eating and physical activity among children and adolescents in the region as well as more globally.

Investigating the sustainability of careers in academic primary care in the United Kingdom.
Adams, Ann; Lester, Helen; Reeve, Joanne; Roberts, Jane; Wilson, Andrew
2014-07-01
The UK Society for Academic Primary Care (SAPC) is re-examining the sustainability of careers in academic primary care (APC). The motivation for this is a number of significant changes within the context of APC since the last such investigation (SAPC, 2003). It is now timely to review the current situation. As a first phase, semi-structured interviews were undertaken with 15 SAPC members from different disciplines and career stages. Findings show that lack of clarity about APC career pathways persist, but important factors linked with sustainability were identified at individual and organisational levels. These include being proactive, developing resilience, mentorship and a positive organisational culture with a strong shared vision about why APC is important. FURTHER RESEARCH: Sustainability is undermined by funding difficulties, lack of integration of members of different APC disciplines, leading to disparities in career progression and lack of clarity about what APC is. Phase 2 will comprise a UK-wide survey.

Many patients experiencing ST segment elevation myocardial infarction (STEMI) are currently treated with primary percutaneous intervention (PCI). This relatively new procedure has reduced the time patients with the diagnosis of STEMI spend in hospital. In this literature review we explore patients' perceptions of their experience of receiving primary percutaneous intervention (PCI) as a treatment for STEMI. We critiqued and graded for relevance 10 papers that included original research and other sources. Key findings indicate that there is considerable variability in how patients treated for STEMI perceive the experience of PCI. Further, there is a misalignment between some patients' perceptions and health professionals' perceptions of this experience related to the event as well as the language used to speak of it. Thus, we recommend that nurses assess patients' perception of the experience and patients' health literacy level, then tailor the content and language of patient and family education to ensure an effective educative intervention.

This study aimed to identify barriers and facilitators of mental health care for patients with trauma histories via qualitative methods with clinicians and administrators from primary care clinics for the underserved. Individual interviews were conducted, followed by a combined focus group with administrators from three jurisdictions; there were three focus groups with clinicians from each clinic system. Common themes were identified, and responses from groups were compared. Administrators and clinicians report extensive trauma histories among patients. Clinician barriers include lack of time, patient resistance, and inadequate referral options; administrators cite reimbursement issues, staff training, and lack of clarity about the term trauma. A key facilitator is doctor-patient relationship. There were differences in perceived barriers and facilitators at the institutional and clinical levels for mental health care for patients with trauma. Importantly, there is agreement about better access to and development of trauma-specific interventions. Findings will aid the development and implementation of trauma-focused interventions embedded in primary care. PMID:22551798

Controversies in imaging of hepatocellular carcinoma: multidetector CT (MDCT)
Silverman, Paul M; Szklaruk, Janio
2005-01-01
Primary hepatocellular carcinoma (HCC) is a significant tumor worldwide and represents the most common primary hepatic neoplasm. Staging criteria are important for appreciation of timely work up of these neoplasms in contradiction with surgical colleagues. This article demonstrates the appearance of HCC on multiphasic, multidetector CT (MDCT) and relates these findings to current staging criteria. The variable appearance on different planes of contrast is critical to appreciate in staging this neoplasm. The hypervascular nature of the primary tumor makes MDCT and three-phase imaging a critical feature in the detection and characterization of this tumor. This is especially critical in the patients who are candidates for surgical resection. Additionally, MDCT has allowed arterial phase imaging to define the vascular supply of the tumor. An accurate representation of the size and number of lesions is critical in not only the initial staging but also the follow-up of hepatocellular carcinoma. The post-treatment features including the appearance post-surgically and after radiofrequency ablation can be well appreciated on MDCT. PMID:16361147

Cognitive impairment poses communication challenges in primary care. Although family "companions" commonly attend primary care visits of older adults with cognitive impairment, little is known about how their involvement affects communication. Therefore, we sought to understand how companion involvement affects the quality of primary care visit communication for older adults with cognitive impairment. Cross-sectional, descriptive qualitative study participants were as follows: (1) English-speaking adults age 65 or older with mild, moderate, or severe cognitive impairment; (2) family members or other unpaid companions who accompany older adults to primary care visits; and (3) primary care clinicians. Twenty semi-structured and in-depth qualitative interviews of older adults and their companions (N = 20 dyads) and two focus groups (N = 10 primary care clinicians) were conducted. Interviews and focus groups were transcribed and analyzed thematically. Family companions commonly facilitate communication by advocating for patients, ensuring the accuracy of information exchange and understanding, and preserving rapport. Significant communication challenges were also identified, including patient and companion role ambiguity, competing visit agendas, and primary care clinician confusion regarding the most accurate source of information. Patients, companions, and clinicians each identified strategies to improve communication, chief among them being to identify, differentiate, and respect both patient and companion priorities and perspectives. Family companions actively participate in primary care visits of older adults with cognitive impairment in ways that promote and inhibit effective communication. Findings suggest the need for strategies that more effectively and purposefully involve family in the care of primary care patients with cognitive impairment. Copyright © 2017 John Wiley & Sons, Ltd.

For health care planning and allocation of resources, realistic estimation of the prevalence of primary aldosteronism is necessary. Reported prevalences of primary aldosteronism are highly variable, possibly due to study heterogeneity. Our objective was to identify and explain heterogeneity in studies that aimed to establish the prevalence of primary aldosteronism in hypertensive patients. PubMed, EMBASE, Web of Science, Cochrane Library, and reference lists from January 1, 1990, to January 31, 2015, were used as data sources. Description of an adult hypertensive patient population with confirmed diagnosis of primary aldosteronism was included in this study. Dual extraction and quality assessment were the forms of data extraction. Thirty-nine studies provided data on 42 510 patients (nine studies, 5896 patients from primary care). Prevalence estimates varied from 3.2% to 12.7% in primary care and from 1% to 29.8% in referral centers. Heterogeneity was too high to establish point estimates (I(2) = 57.6% in primary care; 97.1% in referral centers). Meta-regression analysis showed higher prevalences in studies 1) published after 2000, 2) from Australia, 3) aimed at assessing prevalence of secondary hypertension, 4) that were retrospective, 5) that selected consecutive patients, and 6) not using a screening test. All studies had minor or major flaws. This study demonstrates that it is pointless to claim low or high prevalence of primary aldosteronism based on published reports. Because of the significant impact of a diagnosis of primary aldosteronism on health care resources and the necessary facilities, our findings urge for a prevalence study whose design takes into account the factors identified in the meta-regression analysis.

The organization of after-hours primary medical care services is changing in many countries. Increasing demand, economic considerations and changes in doctors' attitudes are fueling these changes. Information for policy makers in this field is needed. However, a comprehensive review of the international literature that compares the effects of one model of after-hours care with another is lacking. The aim of this study was to carry out a systematic review of the international literature to determine what evidence exists about the effect of different models of out-of-hours primary medical care service on outcome. Original studies and systematic reviews written since 1976 on the subject of 'after-hours primary medical care services' were identified. Databases searched were Medline/Premedline, CINAHL, HealthSTAR, Current Contents, Cochrane Reviews, DARE, EBM Reviews and EconLit. For each paper where the optimal design would have been an interventional study, the 'level' of evidence was assessed as described in the National Health and Medical Research Council Handbook. 'Comparative' studies (levels I, II, III and IV pre-/post-test studies) were included in this review. Six main models of after-hours primary care services (not mutually exclusive) were identified: practice-based services, deputizing services, emergency departments, co-operatives, primary care centres, and telephone triage and advice services. Outcomes were divided into the following categories: clinical outcomes, medical workload, and patient and GP satisfaction. The results indicate that the introduction of a telephone triage and advice service for after-hours primary medical care may reduce the immediate medical workload. Deputizing services increase immediate medical workload because of the low use of telephone advice and the high home visiting rate. Co-operatives, which use telephone triage and primary care centres and have a low home visiting rate, reduce immediate medical workload. There is little evidence on the effect of different service models on subsequent medical workload apart from the finding that GPs working in emergency departments may reduce the subsequent medical workload. There was very little evidence about the advantages of one service model compared with another in relation to clinical outcome. Studies consistently showed patient dissatisfaction with telephone consultations. The rapid growth in telephone triage and advice services appears to have the advantage of reducing immediate medical workload through the substitution of telephone consultations for in-person consultations, and this has the potential to reduce costs. However, this has to be balanced with the finding of reduced patient satisfaction when in-person consultations are replaced by telephone consultations. These findings should be borne in mind by policy makers deciding on the shape of future services.

Increasingly, research is directed at advancing methods to address obesity management in primary care. In this paper we describe the role of interdisciplinary collaboration, or lack thereof, in patient weight management within 12 teams in a large primary care network in Alberta, Canada. Qualitative data for the present analysis were derived from the 5As Team (5AsT) trial, a mixed-method randomized control trial of a 6-month participatory, team-based educational intervention aimed at improving the quality and quantity of obesity management encounters in primary care practice. Participants (n = 29) included in this analysis are healthcare providers supporting chronic disease management in 12 family practice clinics randomized to the intervention arm of the 5AsT trial including mental healthcare workers (n = 7), registered dietitians (n = 7), registered nurses or nurse practitioners (n = 15). Participants were part of a 6-month intervention consisting of 12 biweekly learning sessions aimed at increasing provider knowledge and confidence in addressing patient weight management. Qualitative methods included interviews, structured field notes and logs. Four common themes of importance in the ability of healthcare providers to address weight with patients within an interdisciplinary care team emerged, (i) Availability; (ii) Referrals; (iii) Role perception and (iv) Messaging. However, we find that what was key to our participants was not that these issues be uniformly agreed upon by all team members, but rather that communication and clinic relationships support their continued negotiation. Our study shows that firm clinic relationships and deliberate communication strategies are the foundation of interdisciplinary care in weight management. Furthermore, there is a clear need for shared messaging concerning obesity and its treatment between members of interdisciplinary teams. © 2016 World Obesity.

To evaluate the value of CT-based radiomics signature for differentiating Borrmann type IV gastric cancer (GC) from primary gastric lymphoma (PGL). 40 patients with Borrmann type IV GC and 30 patients with PGL were retrospectively recruited. 485 radiomics features were extracted and selected from the portal venous CT images to build a radiomics signature. Subjective CT findings, including gastric wall peristalsis, perigastric fat infiltration, lymphadenopathy below the renal hila and enhancement pattern, were assessed to construct a subjective findings model. The radiomics signature, subjective CT findings, age and gender were integrated into a combined model by multivariate analysis. The diagnostic performance of these three models was assessed with receiver operating characteristics curves (ROC) and were compared using DeLong test. The subjective findings model, the radiomics signature and the combined model showed a diagnostic accuracy of 81.43% (AUC [area under the curve], 0.806; 95% CI [confidence interval]: 0.696-0.917; sensitivity, 63.33%; specificity, 95.00%), 84.29% (AUC, 0.886 [95% CI: 0.809-0.963]; sensitivity, 86.67%; specificity, 82.50%), 87.14% (AUC, 0.903 [95%CI: 0.831-0.975]; sensitivity, 70.00%; specificity, 100%), respectively. There were no significant differences in AUC among these three models (P=0.051-0.422). Radiomics analysis has the potential to accurately differentiate Borrmann type IV GC from PGL.

With increasing numbers of people living with complex life-limiting multimorbidity in the community, consideration must be given to improving the organisation and delivery of high-quality palliative and end-of-life care (EOLC). To provide insight into the experience of GPs providing EOLC in the community, particularly the facilitators and barriers to good-quality care. A web-based national UK questionnaire survey circulated via the Royal College of General Practitioners, NHS, Marie Curie, and Macmillan networks to GPs. Responses were analysed using descriptive statistics and an inductive thematic analysis. Responses were received from 516 GPs, who were widely distributed in terms of practice location. Of these, 97% felt that general practice plays a key role in the delivery of care to people approaching the end of life and their families. Four interdependent themes emerged from the data: continuity of care - which can be difficult to achieve because of resource concerns including time, staff numbers, increasing primary care workload, and lack of funding; patient and family factors - with challenges including early identification of palliative care needs and recognition of the end of life, opportunity for care planning discussions, and provision of support for families; medical management - including effective symptom-control and access to specialist palliative care services; and expertise and training - the need for training and professional development was recognised to enhance knowledge, skills, and attitudes towards EOLC. The findings reveal enduring priorities for policy, commissioning, practice development, and research in future primary palliative care. © British Journal of General Practice 2016.

The contribution of spatial ability to mathematics achievement in middle childhood.
Gilligan, Katie A; Flouri, Eirini; Farran, Emily K
2017-11-01
Strong spatial skills are associated with success in science, technology, engineering, and mathematics (STEM) domains. Although there is convincing evidence that spatial skills are a reliable predictor of mathematical achievement in preschool children and in university students, there is a lack of research exploring associations between spatial and mathematics achievement during the primary school years. To address this question, this study explored associations between mathematics and spatial skills in children aged 5 and 7years. The study sample included 12,099 children who participated in both Wave 3 (mean age=5; 02 [years; months]) and Wave 4 (mean age=7; 03) of the Millennium Cohort Study. Measures included a standardised assessment of mathematics and the Pattern Construction subscale of the British Ability Scales II to assess intrinsic-dynamic spatial skills. Spatial skills at 5 and 7years of age explained a significant 8.8% of the variation in mathematics achievement at 7years, above that explained by other predictors of mathematics, including gender, socioeconomic status, ethnicity, and language skills. This percentage increased to 22.6% without adjustment for language skills. This study expands previous findings by using a large-scale longitudinal sample of primary school children, a population that has been largely omitted from previous research exploring associations between spatial ability and mathematics achievement. The finding that early and concurrent spatial skills contribute to mathematics achievement at 7years of age highlights the potential of spatial skills as a novel target in the design of mathematics interventions for children in this age range.

There is evidence that people with Parkinson's disease (PD) have a decreased risk of developing cancer. PD has also variably been shown to be associated with an increased risk of cancers like melanoma and breast. We investigated this relationship in a very large cohort of PD patients. We constructed two cohorts of people from an all-England record-linked hospital and mortality dataset spanning 1999-2011. One cohort comprised people with a record of PD; the other comprised people without a record of PD. We 'followed up' these two cohorts to determine observed and expected numbers of people with subsequent primary cancers in each, based on person-years at risk, and calculated standardised rate ratios (RRs). In 219,194 people with PD, the RR for all subsequent primary malignant cancers combined was 0.92 (95% confidence interval (CI) 0.91-0.93). Increased RRs (p<0.05) were found for six out of the 31 cancer types investigated, including breast, melanoma, uterus, kidney, and neurological malignancies. Decreased RRs were found for 11 cancer sites, including lung and colon cancer. We corroborate the findings of a reduced risk for the development of cancers in PD patients shown in smaller studies, including cancers associated and not known to be associated with smoking; and of an increased risk of melanoma and breast cancer. To the best of our knowledge, this is the first study to report an association between PD and elevated rates of uterine and renal cancer. Further work is warranted to understand the mechanisms behind these findings. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aims of the present study were to understand enablers to participation in postgraduate education for primary care nurses (PCNs), and to explore how postgraduate education has advanced their nursing practice. Cross-sectional questionnaires were mailed out in April 2012 to current and past students undertaking postgraduate studies in primary care nursing at The University of Melbourne, Victoria, Australia. Questionnaires were returned by 100 out of 243 nurses (response rate 41%). Ninety-one per cent (91/100) of the respondents were first registered as nurses in Australia. Fifty-seven per cent were hospital trained and 43% were university educated to attain their initial nurse qualification. The respondents reported opportunities to expand scope of practice (99%; 97/98), improve clinical practice (98%; 97/99), increase work satisfaction (93%; 91/98) and increase practice autonomy (92%; 89/97) as factors that most influenced participation in postgraduate education in primary care nursing. Major enablers for postgraduate studies were scholarship access (75%; 71/95) and access to distance education (74%; 72/98). Many respondents reported an increased scope of practice (98%; 95/97) and increased job satisfaction (71%; 70/98) as an education outcome. Only 29% (28/97) cited an increase in pay-rate as an outcome. Of the 73 PCNs currently working in general practice, many anticipated an increase in time spent on the preparation of chronic disease management plans (63%; 45/72), multidisciplinary care plans (56%; 40/72) and adult health checks (56%; 40/72) in the preceding 12 months. Recommendations emerging from findings include: (1) increased access to scholarships for nurses undertaking postgraduate education in primary care nursing is imperative; (2) alternative modes of course delivery need to be embedded in primary care nursing education; (3) the development of Australian primary care policy, including policy on funding models, needs to more accurately reflect the educational level of PCNs, PCN role expansion and the extent of interprofessional collaboration that is evident from research undertaken to date. Nurses with postgraduate education have the potential to increase their scope of practice, take on a greater teaching role and provide more preventive and chronic disease services in primary care. Policies aimed at increasing access to education for nurses working in primary care would strengthen the primary care nursing profession, and enhance the delivery of primary health care services in Australia.

2015-01-01
Summary The 5As Team study was designed to create, implement and evaluate a flexible intervention to improve the quality and quantity of weight management visits in primary care. The objective of this portion of the study was to explore how primary care providers incorporate weight management in their practice. 5AsT is a randomized controlled trial (RCT) on the implementation of a 6‐month 5 As Team (5AsT) intervention designed to operationalize the 5As of obesity management in primary care. Data for the qualitative portion of the study presented here included semi‐structured interviews with 29 multidisciplinary team providers and field notes of intervention sessions. Thematic analysis was undertaken. A key pattern that emerged from the data was that healthcare providers usually do not address obesity as a primary focus for a visit. Rather, obesity is embedded in a wide range of primary care encounters for other conditions. Implications were it can take extra time to discuss weight, it can be inappropriate to bring up weight as a topic, and treating risk factors and root causes of obesity have indirect benefits to patient weight management. Our findings have implications for obesity treatment approaches and tools that assume a discreet weight management visit. The embedded nature of obesity management in primary care can be harnessed to leverage multiple opportunities for asking and assessing root causes of obesity, and working longitudinally towards individual health goals.

In many countries, the number of graduating medical students pursuing a primary care career does not meet demand. These countries face primary care physician shortages. Students' career choices have been widely studied, yet many aspects of this process remain unclear. Conceptual models are useful to plan research and educational interventions in such complex systems.The authors developed a framework of primary care career choice in undergraduate medical education, which expands on previously published models. They used a group-based, iterative approach to find the best way to represent the vast array of influences identified in previous studies, including in a recent systematic review of the literature on interventions to increase the proportion of students choosing a primary care career. In their framework, students enter medical school with their personal characteristics and initial interest in primary care. They complete a process of career decision making, which is subject to multiple interacting influences, both within and outside medical school, throughout their medical education. These influences are stratified into four systems-microsystem, mesosystem, exosystem, and macrosystem-which represent different levels of interaction with students' career choices.This expanded framework provides an updated model to help understand the multiple factors that influence medical students' career choices. It offers a guide for the development of new interventions to increase the proportion of students choosing primary care careers and for further research to better understand the variety of processes involved in this decision.

There is an increasing number of patients with a chronic illness demanding primary care services. This demands for effective self-management support, including collaborative goal setting. Despite the fact that primary care professionals seem to have difficulties implementing goal setting, little information is available about the factors influencing the complexity of this process in primary care. The aim of this study was to contribute to an understanding of the complexity of self-management goal setting in primary care by exploring experts' and primary care professionals' experiences with self-management goal setting and viewpoints regarding influencing factors. A descriptive qualitative research methodology was adopted. Two focus groups and three individual interviews were conducted (total participants n = 17). Thematic content analysis was used to analyse the data. The findings were categorized into four main themes with subordinated subthemes. The themes focus around the complexity of setting non-medical goals and around professionals' skills and attitudes to negotiate and decide about goals with patients. Furthermore, patients' skills and attitudes for goal setting and the integration of goal setting in the time available were formulated as themes. Setting self-management goals in primary care, especially in family medicine, might require a shift from a medical perspective to a biopsychosocial perspective, with an increasing role set aside for the professional to coach the patient in expressing his self-management goals and to take responsibility for these goals. © The Author 2016.

The effects of fuel sulfur content and primary dilution on PM number emissions were investigated during transient operations of an old and a modern diesel engine. Emissions were also studied during steady-state operations in order to confirm consistency with previous findings. Testing methods were concurrent with those implemented by the EPA to regulate PM mass emissions, including the use of the Federal Transient Testing Procedure-Heavy Duty cycle to simulate transient conditions and the use of a Critical Flow Venturi-Constant Volume System to provide primary dilution. Steady-state results were found to be consistent with previous studies in that nuclei-mode particulate emissions were largely reduced when lower-sulfur content fuel was used in the newer engine, while the nuclei-mode PM emissions from the older engine were much less affected by fuel sulfur content. The transient results, however, show that the total number of nuclei-mode PM emissions from both engines increases with fuel sulfur content, although this effect is only seen under the higher primary dilution ratios with the older engine. Transient results further show that higher primary dilution ratios increase total nuclei-mode PM number emissions in both engines.

There are an estimated 15.5 million cancer survivors in the United States, with numbers projected to increase. Many cancer survivors are receiving survivorship care in primary care settings, yet primary care providers report a need for additional training on addressing medical and psychosocial concerns of cancer survivors. This paper presents findings from a pilot study on the effectiveness of a novel training for interprofessional primary care providers on the clinically significant issue of fear of cancer recurrence. The on-site training was provided to a total of 46 participants, including physicians (61%), physician assistants (11%), nurse practitioners (7%), nurses (17%), and social workers (4%) in six different primary care practices. The average number of years of professional experience was 18.8, with standard deviation of 10.9. Results of paired-sample t tests indicated that the training increased knowledge and self-efficacy of providers in identifying and addressing FCR. The training was well-received by participants, who had high confidence in implementing practice behavior changes, although they also identified barriers. Results suggest the feasibility of a brief training for continuing education and have implications for models of care delivery in cancer survivorship.

Skin involvement is reported during primary parvovirus B19 infection in adults. We sought to describe the cutaneous presentations associated with parvovirus B19 primary infection in adults. We conducted a descriptive, retrospective, multicenter study. The patients included (>18 years old) had well-established primary infections with parvovirus B19. Twenty-nine patients were identified between 1992 and 2013 (17 women, 12 men). The elementary dermatologic lesions were mostly erythematous (86%) and often purpuric (69%). Pruritus was reported in 48% of cases. The rash predominated on the legs (93%), trunk (55%), and arms (45%), with a lower frequency of facial involvement (20%). Four different but sometimes overlapping patterns were identified (45%): exanthema, which was reticulated and annular in some cases (80%); the gloves-and-socks pattern (24%); the periflexural pattern (28%); and palpable purpura (24%). The limitations of this study were its retrospective design and possible recruitment bias in tertiary care centers. Our findings suggest that primary parvovirus B19 infection is associated with polymorphous skin manifestations with 4 predominant, sometimes overlapping, patterns. The acral or periflexural distribution of the rash and the presence of purpuric or annular/reticulate lesions are highly suggestive of parvovirus B19 infection.

When a country's health system is faced with fundamental flaws that require the redesign of financing and service delivery, primary healthcare payment systems are often reformed. This study was conducted with the purpose of exploring the experiences of risk-adjusted capitation payment of urban family physicians in Iran when it comes to providing primary health care (PHC). This is a qualitative study using the framework method. Data were collected via digitally audio-recorded semi-structured interviews with 24 family physicians and 5 executive directors in two provinces of Iran running the urban family physician pilot program. The participants were selected using purposive and snowball sampling. The codes were extracted using inductive and deductive methods. Regarding the effects of risk-adjusted capitation on the primary healthcare setting, five themes with 11 subthemes emerged, including service delivery, institutional structure, financing, people's behavior, and the challenges ahead. Our findings indicated that the health system is enjoying some major changes in the primary healthcare setting through the implementation of risk-adjusted capitation payment. With regard to the current challenges in Iran's health system, using risk-adjusted capitation as a primary healthcare payment system can lead to useful changes in the health system's features. However, future research should focus on the development of the risk-adjusted capitation model.

The aim of this study was to assess both psychological distress and personality characteristics associat with primary exercise dependence. A cross-sectional study was carried out with adult habitual physical exercisers. A total of 79 participants voluntarily completed a package of self-report questionnaires including the Exercise Dependence Questionnaire (EDQ), the Eating Disorder Inventory II (EDI-2), the Temperament and Character Inventory (TCI), the Attitude Toward Self scale (ATS), Muscle Dysmorphia Questionnaire (MDQ), and the Symptom Questionnaire (SQ). Significant differences were found in the EDQ exercise for weight control subscale with regard to gender, as well as in the EDI-2 total score and 5 of its subscales, with higher scores for females compared to males. Participants reporting primary exercise dependence (n=32) were more likely to present with disordered eating patterns than controls (n=47). They also showed higher levels of harm avoidance and persistence on the TCI, as well as lower self-directness. Furthermore, primary exercise dependents scored higher on the ATS dysmorphophobia subscale, as well as on the MDQ total score and the anxiety and hostility subscales of the SQ compared to controls. These findings highlight the importance of performing a clinical assessment of psychological symptoms and personality characteristics that might be associated with primary exercise dependence.

Interventions to support recovery after domestic and sexual violence in primary care.
Hegarty, Kelsey; Tarzia, Laura; Hooker, Leesa; Taft, Angela
2016-10-01
Experiences of domestic and sexual violence are common in patients attending primary care. Most often they are not identified due to barriers to asking by health practitioners and disclosure by patients. Women are more likely than men to experience such violence and present with mental and physical health symptoms to health practitioners. If identified through screening or case finding as experiencing violence they need to be supported to recover from these traumas. This paper draws on systematic reviews published in 2013-2015 and a further literature search undertaken to identify recent intervention studies relevant to recovery from domestic and sexual violence in primary care. There is limited evidence as to what interventions in primary care assist with recovery from domestic violence; however, they can be categorized into the following areas: first line response and referral, psychological treatments, safety planning and advocacy, including through home visitation and peer support programmes, and parenting and mother-child interventions. Sexual violence interventions usually include trauma informed care and models to support recovery. The most promising results have been from nurse home visiting advocacy programmes, mother-child psychotherapeutic interventions, and specific psychological treatments (Cognitive Behaviour Therapy, Trauma informed Cognitive Behaviour Therapy and, for sexual assault, Exposure and Eye Movement Desensitization and Reprocessing Interventions). Holistic healing models have not been formally tested by randomized controlled trials, but show some promise. Further research into what supports women and their children on their trajectory of recovery from domestic and sexual violence is urgently needed.

The existence of cancer stem cells within the tumor could lead to cancer therapy resistance. TGFβ1 is considered as one of the most powerful players in the generation of CSCs through induction of epithelial-mesenchymal transition in different types of cancer including lung cancer, however, the detailed mechanisms by which TGFβ1 contribute to EMT induction and CSC maintenance remains unclear. Here, we showed primary lung cancer cells treated by TGFβ1 exhibit mesenchymal features, including morphology and expression of mesenchymal marker in a time-dependent manner. We also observed long-term TGFβ1 exposure leads to an enrichment of a sub-population of CD44 + CD90 + cells which represent CSCs in lung cancer cells. Moreover, the differential expression microRNAs between CSCs and non-CSCs were identified using next-generation sequencing to screen key miRNAs which might contribute to TGFβ1-induced EMT and CSCs generation. Among those differentially expressed miRNAs, the expression of microRNA-138 was time-dependently down-regulated by TGFβ1 treatment. We further demonstrated primary lung cancer cells, in which we knockdown the expression of miR-138, exhibit mesenchymal phenotypes and stem cell properties. Taken together, these findings indicate TGFβ1-induced down-regulation of microRNA-138 contributes to EMT in primary lung cancer cells, and suggest that miR-138 might serve as a potential therapeutic target.

Benzodiazepines are prescribed inappropriately in up to 40% of outpatients. The purpose of this study is to describe a collaborative team-based care model in which clinical pharmacists work with primary care providers (PCPs) to improve the safe use of benzodiazepines for anxiety and sleep disorders and to assess the preliminary results of the impact of the clinical service on patient outcomes. Adult patients were eligible if they received care from the academic primary care clinic, were prescribed a benzodiazepine chronically, and were not pregnant or managed by psychiatry. Outcomes included baseline PCP confidence and knowledge of appropriate benzodiazepine use, patient symptom severity, and medication changes. Twenty-five of 57 PCPs responded to the survey. PCPs reported greater confidence in diagnosing and treating generalized anxiety and panic disorders than sleep disorder and had variable knowledge of appropriate benzodiazepine prescribing. Twenty-nine patients had at least 1 visit. Over 44 total patient visits, 59% resulted in the addition or optimization of a nonbenzodiazepine medication and 46% resulted in the discontinuation or optimization of a benzodiazepine. Generalized anxiety symptom severity scores significantly improved (-2.0; 95% confidence interval (CI): -3.57 to -0.43). Collaborative team-based models that include clinical pharmacists in primary care can assist in optimizing high-risk benzodiazepine use. Although these findings suggest improvements in safe medication use and symptoms, additional studies are needed to confirm these preliminary results.

Purpose The purpose of this paper is to explore work motivation among professionals at well-functioning primary healthcare centers subject to a national healthcare reform which include financial incentives. Design/methodology/approach Five primary healthcare centers in Sweden were purposively selected for being well-operated and representing public/private and small/large units. In total, 43 interviews were completed with different medical professions and qualitative deductive content analysis was conducted. Findings Work motivation exists for professionals when their individual goals are aligned with the organizational goals and the design of the reform. The centers' positive management was due to a unique combination of factors, such as clear direction of goals, a culture of non-hierarchical collaboration, and systematic quality improvement work. The financial incentives need to be translated in terms of quality patient care to provide clear direction for the professionals. Social processes where professionals work together as cohesive groups, and provided space for quality improvement work is pivotal in addressing how alignment is created. Practical implications Leaders need to consistently translate and integrate reforms with the professionals' drives and values. This is done by encouraging participation through teamwork, time for structured reflection, and quality improvement work. Social implications The design of the reforms and leadership are essential preconditions for work motivation. Originality/value The study offers a more complete picture of how reforms are managed at primary healthcare centers, as different medical professionals are included. The value also consists of showing how a range of aspects combine for primary healthcare professionals to successfully manage external reforms.

The pediatric orthopaedics workforce demands, needs, and resources.
Schwend, Richard M
2009-01-01
The Pediatric Orthopaedic Society of North America Practice Management Committee evaluated current and future pediatric orthopaedic workforce needs. The resulting informational article summarizes its findings and makes recommendations for improvement of our workforce. Whereas policy decisions are often in the hands of the government with its emphasis on access and cost containment, the area that we can control, the quality of our workforce should be our primary effort. Specific recommendations include the prospective collection of accurate workforce data, increasing the interest of residents and students to enter our specialty, assisting members to improve practice efficiencies and assuming leadership in the musculoskeletal education of our primary care colleagues. We expect that by improving our workforce and professional work environment, we can make a difference for our young patients and for the society.

Primary retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare tumor: its histogenesis and its biological behavior remain speculative. Since most retroperitoneal tumors are malignant, a preoperative diagnosis of benignity is essential and it can be reached through imaging examinations, allowing a conservative management approach. We describe the case of a 52-year-old woman with abdominal pain and a palpable mass. Computed tomography of the abdomen revealed a retroperitoneal cystic mass, which was resected successfully through laparoscopy and diagnosed as PRMC. Although there are no pathognomonic, clinical or radiological findings for PRMC, it should be included in the list of differential diagnoses and its imaging criteria of benignity should always be sought, with the aim to exclude malignant tumors.

Activation of sensory cortex by imagined genital stimulation: an fMRI analysis.
Wise, Nan J; Frangos, Eleni; Komisaruk, Barry R
2016-01-01
During the course of a previous study, our laboratory made a serendipitous finding that just thinking about genital stimulation resulted in brain activations that overlapped with, and differed from, those generated by physical genital stimulation. This study extends our previous findings by further characterizing how the brain differentially processes physical 'touch' stimulation and 'imagined' stimulation. Eleven healthy women (age range 29-74) participated in an fMRI study of the brain response to imagined or actual tactile stimulation of the nipple and clitoris. Two additional conditions - imagined dildo self-stimulation and imagined speculum stimulation - were included to characterize the effects of erotic versus non-erotic imagery. Imagined and tactile self-stimulation of the nipple and clitoris each activated the paracentral lobule (the genital region of the primary sensory cortex) and the secondary somatosensory cortex. Imagined self-stimulation of the clitoris and nipple resulted in greater activation of the frontal pole and orbital frontal cortex compared to tactile self-stimulation of these two bodily regions. Tactile self-stimulation of the clitoris and nipple activated the cerebellum, primary somatosensory cortex (hand region), and premotor cortex more than the imagined stimulation of these body regions. Imagining dildo stimulation generated extensive brain activation in the genital sensory cortex, secondary somatosensory cortex, hippocampus, amygdala, insula, nucleus accumbens, and medial prefrontal cortex, whereas imagining speculum stimulation generated only minimal activation. The present findings provide evidence of the potency of imagined stimulation of the genitals and that the following brain regions may participate in erogenous experience: primary and secondary sensory cortices, sensory-motor integration areas, limbic structures, and components of the 'reward system'. In addition, these results suggest a mechanism by which some individuals may be able to generate orgasm by imagery in the absence of physical stimulation.

Dermatologic Features of Classic Movie Villains: The Face of Evil.
Croley, Julie Amthor; Reese, Vail; Wagner, Richard F
2017-06-01
Dichotomous dermatologic depictions of heroes and villains in movies have been used since the silent film age. To evaluate the hero-villain skin dichotomy in film by (1) identifying dermatologic findings of the all-time top 10 American film villains, (2) comparing these dermatologic findings to the all-time top 10 American film heroes quantitatively and qualitatively, and (3) analyzing dermatologic portrayals of film villains in depth. In this cross-sectional study, dermatologic findings for film heroes and villains in mainstream media were identified and compared quantitatively using a χ2 test with α < .05, as well as qualitatively. The all-time top 10 American film villains and heroes were obtained from the American Film Institute 100 Greatest Heroes and Villains List. Primary outcomes include identification and frequencies of dermatologic findings of the top 10 film villains and of the top 10 film heroes. Six (60%) of the all-time top 10 American film villains have dermatologic findings, including cosmetically significant alopecia (30%), periorbital hyperpigmentation (30%), deep rhytides on the face (20%), multiple facial scars (20%), verruca vulgaris on the face (20%), and rhinophyma (10%). The top 10 villains have a higher incidence of significant dermatologic findings than the top 10 heroes (60% vs 0%; P = .03). Dermatologic findings of the all-time top 10 American villains are used in film to highlight the dichotomy of good and evil, which may foster a tendency toward prejudice in our society directed at those with skin disease.

Evidence-Based Practice in Liposuction.
Collins, Patrick S; Moyer, Kurtis E
2018-06-01
The goal of this study is to examine the existing peer reviewed literature comparing modern adjunctive techniques in liposuction including laser-assisted liposuction (LAL) and ultrasound-assisted liposuction (UAL) to standard suction-assisted liposuction (SAL). We intend to interpret these findings into a literature-based clinical application to influence practice patterns. A literature review was conducted using a keyword search in PubMed. Keyword search items included liposuction, lipoplasty, suction assisted liposuction, ultrasound assisted liposuction, laser assisted liposuction, tumescent, liposuction comparison, liposuction review, and combinations therein. Exclusion criteria included articles with a primary focus on histologic effects of energy devices, primary animal models, primary opinion papers with no reference to available data, and industry-sponsored publications. Inclusion criteria included articles with direct comparison of liposuction modalities, randomized or blinded studies, and studies with objective outcomes. Twenty-five articles that met the inclusion criteria comparing SAL to UAL or LAL out of 9972 articles identified were obtained. The selected literature was assigned into 3 categories: evidence demonstrating an advantage of 1 modality (SAL, UAL, or LAL) over another, evidence that showed no benefit of 1 modality over another, and evidence that demonstrated risks of complications of 1 modality over another. The benefits of UAL and LAL over SAL include the following: (1) UAL over SAL in the treatment of gynecomastia, (2) LAL and UAL over SAL with decreased hemoglobin/hematocrit in high-volume lipoaspirates, and (3) LAL over SAL with skin tightening in select areas specifically the submental area. Otherwise, the literature demonstrates equivocal results among the described techniques with no clear benefit to set one apart from the other. There appears to be no demonstrable added benefit to the addition of either UAL or LAL that would urge a change in practice patterns outside the exceptions listed.

Tridax procumbens flavonoids promote osteoblast differentiation and bone formation.
Al Mamun, Md Abdullah; Hosen, Mohammad Jakir; Islam, Kamrul; Khatun, Amina; Alam, M Masihul; Al-Bari, Md Abdul Alim
2015-11-18
Tridax procumbens flavonoids (TPFs) are well known for their medicinal properties among local natives. Besides traditionally used for dropsy, anemia, arthritis, gout, asthma, ulcer, piles, and urinary problems, it is also used in treating gastric problems, body pain, and rheumatic pains of joints. TPFs have been reported to increase osteogenic functioning in mesenchymal stem cells. Our previous study showed that TPFs were significantly suppressed the RANKL-induced differentiation of osteoclasts and bone resorption. However, the effects of TPFs to promote osteoblasts differentiation and bone formation remain unclear. TPFs were isolated from Tridax procumbens and investigated for their effects on osteoblasts differentiation and bone formation by using primary mouse calvarial osteoblasts. TPFs promoted osteoblast differentiation in a dose-dependent manner demonstrated by up-regulation of alkaline phosphatase and osteocalcin. TPFs also upregulated osteoblast differentiation related genes, including osteocalcin, osterix, and Runx2 in primary osteoblasts. TPFs treated primary osteoblast cells showed significant upregulation of bone morphogenetic proteins (BMPs) including Bmp-2, Bmp-4, and Bmp-7. Addition of noggin, a BMP specific-antagonist, inhibited TPFs induced upregulation of the osteocalcin, osterix, and Runx2. Our findings point towards the induction of osteoblast differentiation by TPFs and suggested that TPFs could be a potential anabolic agent to treat patients with bone loss-associated diseases such as osteoporosis.

Ogunyemi, Dotun; Bazargan, Mohsen; Norris, Keith; Jones-Quaidoo, Sean; Wolf, Kenneth; Edelstein, Ronald; Baker, Richard S; Calmes, Daphne
2005-01-01
The objective of this study was to describe the development of a primary care medical student's thesis. In 1995, as part of its primary care clerkship, the Charles R. Drew University of Medicine and Science (Drew University), College of Medicine created a curriculum requiring medical students to develop, design, and implement a research project during their 2-year longitudinal clinical experience. For this study, we reviewed all student research projects generated between 1995 and 2004. Among the 112 research projects, topics covered included internal medicine (29.5%), obstetrics and gynecology (OBGYN; 22%), psychosocial issues (20.5%), pediatrics (9%), public health/epidemiology (8%), medical education (8%), and surgery (3%). Mentors included faculty from internal medicine (16%), dean's office (16%), pediatrics (13%), family medicine (11%), non-Drew faculty (10%), OBGYN (9%), psychiatry (9%), surgery (9%), emergency medicine (4%), and pathology/radiology departments (3%). The students' survey showed that 83% agreed that the mentors were valuable, 72% admitted that their knowledge about the research process was improved, about 50% indicated that they were more competitive during residency application, and 80% claimed that they obtained satisfaction from accomplishing a goal. Students are able to conduct and present a primary care research project as a requirement of their medical training. Most students find the experience beneficial and positive.

Pregnancy as Foreground in Cystic Fibrosis Carrier Testing Decisions in Primary Care
Williams, Janet K.
2009-01-01
Cystic fibrosis carrier testing (CFCT) is among the first of the DNA tests offered prenatally in primary care settings. This paper from a descriptive qualitative study describes the influence of pregnancy in CFCT decisions by women receiving community-based prenatal care. Twenty-seven women receiving prenatal care in Midwestern U.S. primary care clinics completed semistructured interviews. Audiotaped interviews were analyzed using content analysis. Participants described decision-making influences and strategies from the perspective of “being pregnant.” Patterns of attitudes and beliefs include (1) dealing with emotions, (2) pregnancy is natural, and (3) thinking about the baby. Strategies in the decision-making process included (1) reducing stress, (2) choosing what is relevant, (3) doing everything right, (4) wanting to be prepared, (5) delaying information, and (6) trusting God. While other factors were mentioned by some women, major themes reflect the influence of currently being pregnant on the decision-making process. These findings suggest that pregnancy is a powerful influence on the decision-making process and may not be the optimal time to make fully informed decisions regarding genetic carrier testing. Further understanding of factors influencing the genetic testing decision-making process is needed. Offering CFCT prior to conception is advocated. PMID:19309287

Orbital evolution of small binary asteroids
NASA Astrophysics Data System (ADS)
Ćuk, Matija; Nesvorný, David
2010-06-01
About 15% of both near-Earth and main-belt asteroids with diameters below 10 km are now known to be binary. These small asteroid binaries are relatively uniform and typically contain a fast-spinning, flattened primary and a synchronously rotating, elongated secondary that is 20-40% as large (in diameter) as the primary. The principal formation mechanism for these binaries is now thought to be YORP (Yarkovsky-O'Keefe-Radzievskii-Paddack) effect induced spin-up of the primary followed by mass loss and accretion of the secondary from the released material. It has previously been suggested (Ćuk, M. [2007]. Astrophys. J. 659, L57-L60) that the present population of small binary asteroids is in a steady state between production through YORP and destruction through binary YORP (BYORP), which should increase or decrease secondary's orbit, depending on the satellite's shape. However, BYORP-driven evolution has not been directly modeled until now. Here we construct a simple numerical model of the binary's orbital as well the secondary's rotational dynamics which includes BYORP and selected terms representing main solar perturbations. We find that many secondaries should be vulnerable to chaotic rotation even for relatively low-eccentricity mutual orbits. We also find that the precession of the mutual orbit for typical small binary asteroids might be dominated by the perturbations from the prolate and librating secondary, rather than the oblate primary. When we evolve the mutual orbit by BYORP we find that the indirect effects on the binary's eccentricity (through the coupling between the orbit and the secondary's spin) dominate over direct ones caused by the BYORP acceleration. In particular, outward evolution causes eccentricity to increase and eventually triggers chaotic rotation of the secondary. We conclude that the most likely outcome will be reestablishing of the synchronous lock with a "flipped" secondary which would then evolve back in. For inward evolution we find an initial decrease of eccentricity and secondary's librations, to be followed by later increase. We think that it is likely that various forms of dissipation we did not model may damp the secondary's librations close to the primary, allowing for further inward evolution and a possible merger. We conclude that a merger or a tidal disruption of the secondary are the most likely outcomes of the BYORP evolution. Dissociation into heliocentric pairs by BYORP alone should be very difficult, and satellite loss might be restricted to the minority of systems containing more than one satellite at the time.

Respiratory tract infections (RTIs) are the most common reason for primary care (PC) consultations and for antibiotic prescribing and use. The majority of RTIs have a viral aetiology however, and antibiotic consumption is ineffective and unnecessary. Inappropriate antibiotic use contributes greatly to antibiotic resistance (ABR) leading to complications, increased adverse events, reconsultations and costs. Improving antibiotic consumption is thus crucial to containing ABR, which has become an urgent priority worldwide. We will systematically review the evidence about interventions aimed at improving the quality of antibiotic prescribing and use for acute RTI. We will include primary peer-reviewed and grey literature of studies conducted on in-hours and out-of-hours PC patients (adults and children): (1) randomised controlled trials (RCTs), quasi-RCTs and/or cluster-RCTs evaluating the effectiveness, feasibility and acceptability of patient-targeted and clinician-targeted interventions and (2) RCTs and other study designs evaluating the effectiveness of public campaigns and regulatory interventions. We will search MEDLINE (EBSCOHost), EMBASE (Elsevier), the Cochrane Library (Wiley), CINHAL (EBSCOHost), PsychINFO (EBSCOHost), Web of Science, LILACS (Latin American and Caribbean Literature on Health Sciences), TRIP (Turning Research Into Practice) and opensgrey.eu without language restriction. We will also search the reference lists of included studies and relevant reviews. Primary outcomes include the rates of (guideline-recommended) antibiotics prescribed and/or used. Secondary outcomes include immediate or delayed use of antibiotics, and feasibility and acceptability outcomes. We will assess study eligibility and risk of bias, and will extract data. Data permitting, we will perform meta-analyses. This is a systematic review protocol and so formal ethical approval is not required. We will not collect confidential, personal or primary data. The findings of this review will be disseminated at national and international scientific meetings.

Feedlot Euthanasia and Necropsy.
Griffin, Dee
2015-11-01
Timely euthanasia of feeder cattle can minimize suffering of cattle that have little hope of recovery or pain abatement. Euthanasia techniques are described, including primary and secondary steps to ensure humane death. Considerations are discussed to ensure rendered product from euthanized cattle will be safe. A necropsy technique that is time efficient and thorough is outlined. An important aspect is minimizing the number of detached body organs, thereby making it easier to remove the necropsied animal. A necropsy data collection system is discussed that uses check-boxes to record findings. A link to a database that can be downloaded is included. Copyright © 2015 Elsevier Inc. All rights reserved.

Bioethics for clinicians: 17. Conflict of interest in research, education and patient care
Lemmens, T; Singer, P A
1998-01-01
A conflict of interest occurs in a situation in which professional judgement regarding a primary interest, such as research, education or patient care, may be unduly influenced by a secondary interest, such as financial gain or personal prestige. Conflicts of interest exist in every walk of life, including medicine and science. There is nothing inherently unethical in finding oneself in a conflict of interest. Rather, the key questions are whether one recognizes the conflict and how one deals with it. Strategies include disclosing the conflict, establishing a system of review and authorization, and prohibiting the activities that lead to the conflict. PMID:9834723

Post-hoc secondary data analysis with no prespecified hypotheses has been discouraged by textbook authors and journal editors alike. Unfortunately no single term describes this phenomenon succinctly. I would like to coin the term "sigsearch" to define this practice and bring it within the teaching lexicon of statistics courses. Sigsearch would include any unplanned, post-hoc search for statistical significance using multiple comparisons of subgroups. It would also include data analysis with outcomes other than the prespecified primary outcome measure of a study as well as secondary data analyses of earlier research.

Neurostimulation in the treatment of primary headaches
Miller, Sarah; Sinclair, Alex J; Davies, Brendan; Matharu, Manjit
2016-01-01
There is increasing interest in using neurostimulation to treat headache disorders. There are now several non-invasive and invasive stimulation devices available with some open-label series and small controlled trial studies that support their use. Non-invasive stimulation options include supraorbital stimulation (Cefaly), vagus nerve stimulation (gammaCore) and single-pulse transcranial magnetic stimulation (SpringTMS). Invasive procedures include occipital nerve stimulation, sphenopalatine ganglion stimulation and ventral tegmental area deep brain stimulation. These stimulation devices may find a place in the treatment pathway of headache disorders. Here, we explore the basic principles of neurostimulation for headache and overview the available methods of neurostimulation. PMID:27152027

The Menominee Indian Tribe of Wisconsin has the highest smoking rate in the state. To address the resultant health disparities, the tribe conducted a qualitative pilot project to examine tobacco use. The findings indicated mainstream models of addiction did not capture the tribe’s context well; the Indigenist Stress-Coping Model was most applicable. Participants suggested that Menominee-centric ways of knowing related to commercial and sacred tobacco use should be included in all levels of prevention as a key strategy. Recommendations include primary prevention targeted specifi ally to youth, pregnant women, and adults who care for children, as well as access to commercial tobacco products. PMID:24352817

Introduction Obesity and overweight are an emerging problem in Africa. Obese children are at increased risk of developing hypertension, high cholesterol, orthopaedic problems and type 2 diabetes as well as increased risk of adult obesity. Prevention of childhood overweight and obesity therefore needs high priority. The review approach is particularly useful in establishing whether research findings are consistent and can be generalised across populations and settings. This systematic review aims to assess the magnitude and distribution of overweight and obesity among primary school learners within populations in Africa. Methods and analysis A comprehensive search of key bibliographic databases including MEDLINE (PubMed), MEDLINE (EbscoHost), CINAHL (EbscoHost), Academic Search Complete (EbscoHost) and ISI Web of Science (Science Citation Index) will be conducted for published literature. Grey literature will be also be obtained. Full-text articles of eligible studies will be obtained and screened following predefined inclusion criteria. The quality of reporting as well as risk of bias of included studies will be assessed, data extracted and synthesised. The results will be summarised and presented by country and major regional groupings. Meta-analysis will be conducted for identical variables across studies. This review will be reported following the MOOSE Guidelines for Meta-Analysis and Systematic Reviews of Observational Studies. Ethics and dissemination Ethics is not a requirement since no primary data will be collected. All data that will be presented in this review are based on published articles. The findings of this systematic review will be submitted for publication in peer-reviewed journals and disseminated in national and international conferences and also in policy documents to appropriate bodies for decision-making, where needed. It is expected that the findings will identify some research gaps for further studies. PMID:28087553

Health perceptions in patients who undergo screening and workup for prostate cancer.
Katz, David A; Jarrard, David F; McHorney, Colleen A; Hillis, Stephen L; Wiebe, Donald A; Fryback, Dennis G
2007-02-01
False-positive screening tests may induce persistent psychological distress. This study was designed to determine whether a positive screening test with negative biopsy findings for prostate cancer is associated with worsened mental health during short-term follow-up. We conducted a cross-sectional telephone survey of two groups of men approximately 2 months after testing: group 1, 109 men with an abnormal prostate-specific antigen level or digital rectal examination findings but with negative biopsy findings for prostate cancer; and group 2, 101 age-matched primary care patients with PSA screening levels in the reference range (less than 4 ng/mL). Primary outcomes included state anxiety and prostate cancer-related worry. Secondary outcomes included Medical Outcomes Study Short Form 36-item Health Survey subscales and sexual function items. Multivariate regression techniques were used to adjust for differences in baseline covariates. Group 1 patients were more worried than group 2 patients about getting prostate cancer (mean worry 3.9 versus 4.5, P = 0.0001, using a 5-point scale, with 1 indicating extreme worry and 5 no worry). Group 1 patients also perceived their risk of prostate cancer to be significantly greater than that of controls (P = 0.001). No significant differences were found across state anxiety or Medical Outcomes Study Short Form 36-item Health Survey subscales. Sexual bother was greater for group 1 patients, with 19% reporting that sexual function was a moderate to big problem compared with 10% of group 2 patients (P = 0.0001). Men with abnormal prostate cancer screening tests report increased cancer-related worry and more problems with sexual function, despite having a negative biopsy result. Effective counseling interventions are needed before prostate cancer screening and during follow-up.

Physician wages across specialties: informing the physician reimbursement debate.
Leigh, J Paul; Tancredi, Daniel; Jerant, Anthony; Kravitz, Richard L
2010-10-25
Disparities in remuneration between primary care and other physician specialties may impede health care reform by undermining the sustainability of a primary care workforce. Previous studies have compared annual incomes across specialties unadjusted for work hours. Wage (earnings-per-hour) comparisons could better inform the physician payment debate. In a cross-sectional analysis of data from 6381 physicians providing patient care in the 2004-2005 Community Tracking Study (adjusted response rate, 53%), we compared wages across broad and narrow categories of physician specialties. Tobit and linear regressions were run. Four broad specialty categories (primary care, surgery, internal medicine and pediatric subspecialties, and other) and 41 specific specialties were analyzed together with demographic, geographic, and market variables. In adjusted analyses on broad categories, wages for surgery, internal medicine and pediatric subspecialties, and other specialties were 48%, 36%, and 45% higher, respectively, than for primary care specialties. In adjusted analyses for 41 specific specialties, wages were significantly lower for the following than for the reference group of general surgery (wage near median, $85.98): internal medicine and pediatrics combined (-$24.36), internal medicine (-$24.27), family medicine (-$23.70), and other pediatric subspecialties (-$23.44). Wage rankings were largely impervious to adjustment for control variables, including age, race, sex, and region. Wages varied substantially across physician specialties and were lowest for primary care specialties. The primary care wage gap was likely conservative owing to exclusion of radiologists, anesthesiologists, and pathologists. In light of low and declining medical student interest in primary care, these findings suggest the need for payment reform aimed at increasing incomes or reducing work hours for primary care physicians.

We aim to describe the health-related quality of life of informal carers and their experiences of primary care. Responses from the 2011-12 English General Practice Patient Survey, including 195,364 informal carers, were analysed using mixed effect logistic regressions controlling for age, gender, ethnicity and social deprivation to describe carer health-related quality of life (mobility, self-care, usual activities, pain, and anxiety/depression, measured using EQ-5D) and primary care experience (access, continuity and communication). Informal carers reported poorer health-related quality of life than non-carers of similar age, gender, ethnicity and social deprivation. Increasing caring commitment was associated with worse EQ-5D scores, with carers of 50+ hours a week scoring 0.05 points lower than non-carers (95 % CI 0.05 to 0.04), equivalent to 18 fewer days of full health annually. Considering each domain of EQ-5D separately, carers of 50+ hours/week were more likely to report pain OR = 1.53 (1.50-1.57), p < 0.0001, and anxiety/depression OR = 1.69 (1.66-1.73), p < 0.0001, than non-carers. Younger carers scored lower on EQ-5D than non-carer peers but the converse was true among over-85s. In the most deprived areas carers reported the equivalent of 37 fewer days of full health annually than carers in the most affluent areas. On average, carers reported poorer patient experiences in all areas of primary care than non-carers (odds ratios 0.84-0.97), with this difference being most marked in the domain of access. Informal carers experience a double disadvantage of poorer health-related quality of life and poorer patient experience in primary care. We find no evidence for health benefits of caregiving. We recommend physicians identify and treat carer health problems, including pain and anxiety/depression, particularly among young, deprived and high time-commitment carers. Improving patient experience for carers, including access to primary care, should be a priority.

Objective To determine the feasibility of a randomised controlled trial of an internet intervention for low back pain (LBP) using three arms: (1) usual care, (2) usual care plus an internet intervention or (3) usual care plus an internet intervention with additional physiotherapist telephone support. Design and setting A three-armed randomised controlled feasibility trial conducted in 12 general practices in England. Participants Primary care patients aged over 18 years, with current LBP, access to the internet and without indicators of serious spinal pathology or systemic illness. Interventions The ‘SupportBack’ internet intervention delivers a 6-week, tailored programme, focused on graded goal setting, self-monitoring and provision of tailored feedback to encourage physical activity. Additional physiotherapist telephone support consisted of three brief telephone calls over a 4-week period, to address any concerns and provide reassurance. Outcomes The primary outcomes were the feasibility of the trial design including recruitment, adherence and retention at follow-up. Secondary descriptive and exploratory analyses were conducted on clinical outcomes including LBP-related disability at 3 months follow-up. Results Primary outcomes: 87 patients with LBP were recruited (target 60–90) over 6 months, and there were 3 withdrawals. Adherence to the intervention was higher in the physiotherapist-supported arm, compared with the stand-alone internet intervention. Trial physiotherapists adhered to the support protocol. Overall follow-up rate on key clinical outcomes at 3 months follow-up was 84%. Conclusions This study demonstrated the feasibility of a future definitive randomised controlled trial to determine the clinical and cost-effectiveness of the SupportBack intervention in primary care patients with LBP. Trial registration number ISRCTN31034004; Results. PMID:29525768

The effectiveness of air pollution emission control policies can be evaluated by examining ambient pollutant concentration trends that are observed at a large number of ground monitoring sites over time. In this paper, we used ground monitoring measurements in conjunction with satellite aerosol optical depth (AOD) data to investigate fine particulate matter (PM2.5; particulate matter with aerodynamic diameter ≤2.5 μm) trends and their spatial patterns over a large U.S. region, New England, during 2000–2008. We examined the trends in rural and urban areas to get a better insight about the trends of regional and local source emissions. Decreases in PM2.5 concentrations (μg/m3) were more pronounced in urban areas than in rural ones. In addition, the highest and lowest PM2.5 decreases (μg/m3) were observed for winter and summer, respectively. Together, these findings suggest that primary particle concentrations decreased more relative to secondary ones. This is also supported by the analysis of the speciation data which showed that downward trends of primary pollutants including black carbon were stronger than those of secondary pollutants including sulfate. Furthermore, this study found that ambient primary pollutants decreased at the same rate as their respective source emissions. This was not the case for secondary pollutants which decreased at a slower rate than that of their precursor emissions. This indicates that concentrations of secondary pollutants depend not only on the primary emissions but also on the availability of atmospheric oxidants which might not change during the study period. This novel approach of investigating spatially varying concentration trends, in combination with ground PM2.5 species trends, can be of substantial regulatory importance. PMID:24906074

Second cancers in patients with male breast cancer: a literature review.
Grenader, Tal; Goldberg, Anthony; Shavit, Linda
2008-06-01
The risk of second malignancies among female breast cancer patients has been studied for decades. In contrast, very little is known about second primary tumors in men. Risk factors for breast cancer in men, including genetic, hormonal and environmental factors, provide parallels to the etiology of breast cancer in women. This review considers the literature related to the risk of developing a second cancer in patients with male breast cancer. A systematic review of the literature between 1966 and 2007 was conducted and acceptable articles used for analysis. All retrieved articles were screened to identify any papers that had been missed. Studies were included if they discussed the risk of subsequent malignancy in patients with male breast cancer. Patients with history of male breast cancer have an increased risk of a second ipsilateral, or contralateral breast cancer (standardized incidence ratio 30-110). The risk of subsequent contralateral breast cancer was highest in men under 50 years of age at the time of the diagnosis of the initial cancer. The data on non-breast second primary cancers is diverse. One study has suggested an increased incidence of cancers of the small intestine, prostate, rectum and pancreas, and of non-melanoma skin cancer and myeloid leukaemia. Other investigators did not find an increase in the overall risk of subsequent cancer development in men diagnosed initially with primary breast cancer. Although sarcoma, lung and esophageal cancers are well recognized complications of radiation therapy for female breast cancer, there is no evidence for the association of these cancers following radiation therapy in male breast cancer. Although the incidence of second primary cancer in patients with primary male breast cancer requires further study, male breast cancer survivors should probably undergo periodic screening for the early detection of second breast cancers and other adverse health effects.

Takahashi, Kentaro; Kagami, Shin-Ichiro; Kawashima, Hirotoshi; Kashiwakuma, Daisuke; Suzuki, Yoshio; Iwamoto, Itsuo
2016-01-01
We herein describe a second Japanese case of sarcoidosis presenting Addison's disease. A 52-year-old man was diagnosed with sarcoidosis based on clinical and laboratory findings, including bilateral hilar lymphadenopathy and elevated levels of serum angiotensin-converting enzyme and lysozyme, as well as the presence of noncaseating epithelioid granulomas. The patient also exhibited general fatigue, pigmentation, weight loss, hypotension and hyponatremia, suggestive of chronic adrenocortical insufficiency. An endocrine examination confirmed primary adrenocortical insufficiency. This case suggests the direct involvement of sarcoid granuloma in the adrenal glands.

Dentists versus auto mechanics: are there ethical differences?
Riley, Crystal
2013-01-01
The different ethical perspectives of dentists and auto mechanics include primary concern, billing procedures, advertising, emergency care, the level of autonomy granted to their patients/ clients, the amount of disclosure given to their patients/clients, the ability to judge the work of others, and the freedom to pursue romantic relationships with their patients/clients. In analyzing these differences, one finds dentists to have much greater ethical obligations than auto mechanics. There are subtle differences between the ethical expectations of Canadian and United States dentists.

[Clinical characteristic of secondary hypertension in the elderly].
Kohara, Katsuhiko
2005-06-01
The prevalence of secondary hypertension is higher in the elderly population. Renal hypertension is the most prevalent. The prevalence of renovascular hypertension (RVH) increases with age. Since RVH in the elderly is frequently associated with systemic atherosclerosis, other atherosclerotic disorders including ischemic heart disease need to be evaluated. The prevalence of primary aldosteronism and Cushing's syndrome decreases with age, while that of pheochromocytoma persists in the elderly population. Due to lack of classical symptoms, special attention should be paid to find pheochromocytoma in the elderly.

Staple line and anastomotic leakages are life-threatening complications after bariatric surgery. Upper gastrointestinal (GI) tract X-ray examination with oral administration of a water-soluble contrast agent can be used to detect leaks. The aim of this study was to evaluate the impact of routine upper GI tract fluoroscopy after primary bariatric surgery. Between January 2009 and December 2014 a total of 658 bariatric interventions were carried out of which 442 were primary bariatric operations. Included in this single center study were 307 sleeve gastrectomies and 135 Roux-en-Y gastric bypasses. Up to December 2012 upper GI tract fluoroscopy was performed routinely between the first and third postoperative days and the detection of leakages was evaluated. In the investigation period 8 leakages (2.6 %) after sleeve gastrectomy, 1 anastomotic leakage in gastrojejunostomy and 1 in jejunojejunostomy after Roux-en-Y gastric bypass occurred. All patients developed clinical symptoms, such as abdominal pain, tachycardia or fever. In one case the leakage was detected by upper GI fluoroscopy and in nine cases radiological findings were unremarkable. No leakages were detected in asymptomatic patients. Routine upper GI fluoroscopy is not recommended for uneventful postoperative courses after primary bariatric surgery.

This study was to compare the success of resin-modified Portland cement-based material (TheraCal) with MTA in direct pulp capping (DPC) of primary molars. Symmetrical bilateral primary molars (92) from 46 healthy subjects aged 5-7 years were included in this split-mouth randomised clinical trial. DPC for small non-contaminated pulp exposures using either TheraCal or MTA were randomly performed in symmetrical molars. Thereafter, teeth were restored with amalgam. Clinical and radiographic evaluations were performed at 6 and 12 month follow-ups. Data were analysed using Chi square test at a significance level of 0.05. At the final follow-up session 74 teeth were available. After 12 months, the overall success rates for MTA and TheraCal were 94.5 and 91.8%, respectively. The difference between outcomes of the two groups was not statistically significant (P > 0.05). Within the limitations of the current study, radiographic and clinical findings revealed that TheraCal exhibited a comparable outcome to MTA in DPC of primary molars after 12 months.

Provider and interpreter preferences among Somali women in a primary care setting.
Odunukan, Olufunso W; Abdulai, Raolat M; Hagi Salaad, Misbil F; Lahr, Brian D; Flynn, Priscilla M; Wieland, Mark L
2015-04-01
Somali people are among the largest refugee populations to resettle in North America and Europe over the past 2 decades, and health disparities are well documented, including barriers to effective navigation of primary health care systems. Patient-provider gender discordance has been described as a barrier to health-seeking behaviors and effective communication by Somali women in past qualitative work. The objective of this study was to elucidate provider and interpreter preferences during clinical encounters according to gender and race among Somali women in the United States. Fifty Somali women empanelled to a large primary care practice completed pictorial surveys to elucidate preferences of Somali women for providers of different genders and race for different components of the clinical examination using a Likert-type scale. We found that Somali women generally preferred a female provider for conducting the physical examination, particularly for the pelvic, breast, and abdominal examinations. Likewise, Somali women strongly preferred female interpreters to be present during the physical examination. There was no stated preference for patient-provider racial concordance. These findings have implications for structural health care changes aimed at delivering culturally sensitive and effective primary care to Somali patients. © The Author(s) 2014.

Optimal apparent damping as a function of the bandwidth of an array of vibration absorbers.
Vignola, Joseph; Glean, Aldo; Judge, John; Ryan, Teresa
2013-08-01
The transient response of a resonant structure can be altered by the attachment of one or more substantially smaller resonators. Considered here is a coupled array of damped harmonic oscillators whose resonant frequencies are distributed across a frequency band that encompasses the natural frequency of the primary structure. Vibration energy introduced to the primary structure, which has little to no intrinsic damping, is transferred into and trapped by the attached array. It is shown that, when the properties of the array are optimized to reduce the settling time of the primary structure's transient response, the apparent damping is approximately proportional to the bandwidth of the array (the span of resonant frequencies of the attached oscillators). Numerical simulations were conducted using an unconstrained nonlinear minimization algorithm to find system parameters that result in the fastest settling time. This minimization was conducted for a range of system characteristics including the overall bandwidth of the array, the ratio of the total array mass to that of the primary structure, and the distributions of mass, stiffness, and damping among the array elements. This paper reports optimal values of these parameters and demonstrates that the resulting minimum settling time decreases with increasing bandwidth.

Genetic analysis--a diagnostic tool for primary hyperoxaluria type I.
Milosevic, Danko; Rinat, Choni; Batinic, Danica; Frishberg, Yaacov
2002-11-01
Primary hyperoxaluria type I is an autosomal recessive metabolic disease in which excessive oxalates are formed by the liver and excreted by the kidneys, causing a wide spectrum of disease, ranging from renal failure in infancy to mere renal stones in late adulthood. The diagnosis may be suspected when clinical signs and increased urinary oxalate and glycolate excretion present, and is confirmed by the measurement of decreased alanine:glyoxylate aminotransferase activity in a liver sample. The enzymatic assay is not readily available to pediatric nephrologists in many parts of the world. We describe three families from Croatia in whom the diagnosis of primary hyperoxaluria was solely based on clinical findings that included nephrolithiasis and nephrocalcinosis accompanied by increased urinary oxalates and glycolate excretion, as enzymatic assays of liver samples could not be performed. Mutation analysis of the AGXT gene encoding the defective enzyme confirmed the diagnosis, revealing three alleles carrying the C156ins mutation and two the G630A mutation. Screening first-degree relatives for the relevant mutation disclosed an asymptomatic affected sibling. Mutation analysis of the AGXT gene is a non-invasive and accurate tool for the diagnosis of type I primary hyperoxaluria that may replace enzymatic assays of liver biopsies.

Towards implementing coordinated healthy lifestyle promotion in primary care: a mixed method study.
Thomas, Kristin; Bendtsen, Preben; Krevers, Barbro
2015-01-01
Primary care is increasingly being encouraged to integrate healthy lifestyle promotion in routine care. However, implementation has been suboptimal. Coordinated care could facilitate lifestyle promotion practice but more empirical knowledge is needed about the implementation process of coordinated care initiatives. This study aimed to evaluate the implementation of a coordinated healthy lifestyle promotion initiative in a primary care setting. A mixed method, convergent, parallel design was used. Three primary care centres took part in a two-year research project. Data collection methods included individual interviews, document data and questionnaires. The General Theory of Implementation was used as a framework in the analysis to integrate the data sources. Multi-disciplinary teams were implemented in the centres although the role of the teams as a resource for coordinated lifestyle promotion was not fully embedded at the centres. Embedding of the teams was challenged by differences among the staff, patients and team members on resources, commitment, social norms and roles. The study highlights the importance of identifying and engaging key stakeholders early in an implementation process. The findings showed how the development phase influenced the implementation and embedding processes, which add aspects to the General Theory of Implementation.

In the present study, human primary oral squamous carcinoma cells treated with cisplatin and 5-fluorouracil were analyzed, for the first time, by in vitro FTIR Microspectroscopy (FTIRM), to improve the knowledge on the biochemical pathways activated by these two chemotherapy drugs. To date, most of the studies regarding FTIRM cellular analysis have been executed on fixed cells from immortalized cell lines. FTIRM analysis performed on primary tumor cells under controlled hydrated conditions provides more reliable information on the biochemical processes occurring in in vivo tumor cells. This spectroscopic analysis allows to get on the same sample and at the same time an overview of the composition and structure of the most remarkable cellular components. In vitro FTIRM analysis of primary oral squamous carcinoma cells evidenced a time-dependent drug-specific cellular response, also including apoptosis triggering. Furthermore, the univariate and multivariate analyses of IR data evidenced meaningful spectroscopic differences ascribable to alterations affecting cellular proteins, lipids and nucleic acids. These findings suggest for the two drugs different pathways and extents of cellular damage, not provided by conventional cell-based assays (MTT assay and image-based cytometry).

Human papilloma virus (HPV) infection is the crucial step in the initiation of cervical carcinomas. In addition, HPV18 has been implicated in tumour progression and adverse clinical outcome. We determined the HPV types in 12 primary cervical carcinomas and 12 cell lines and compared the findings with the comparative genetic hybridisation (CGH) pattern of chromosomal alterations. The most frequent alteration was the deletion at 3p14 followed by the loss of 2q34-q36 along with 3q gain. High risk HPV types were detected in all samples except one primary tumour. In contrast to the normal distribution, HPV18 was present in 75% of cases including all cell lines. The cell lines carried a higher number of genetic alterations and a different CGH pattern for several chromosomes than the primary tumours, despite microdissection. Purely HPV18 positive cases indicated a high incidence of imbalances at specific loci with peaks of the histogram coinciding with known HPV integration sites. The study suggests that HPV infection is associated with a recurrent pattern of chromosomal changes in cervical carcinomas and that the development and progression of these alterations is triggered by integration into the host genome.

Diagnosis and management of endometriosis: the role of the advanced practice nurse in primary care.
Mao, Alexandra J; Anastasi, Joyce K
2010-02-01
To discuss the etiology, clinical presentation, diagnosis, and management of endometriosis for the advanced practice nurse (APN) in primary care. Selected research, clinical studies, clinical practice guidelines, and review articles. Commonly encountered by the APN in primary care, endometriosis is a chronic, progressive inflammatory disease characterized by endometrial lesions, cysts, fibrosis, or adhesions in the pelvic cavity, causing chronic pelvic pain and infertility in women of reproductive age. Because of its frequently normal physical examination findings, variable clinical presentations, and nonspecific, overlapping symptoms with other conditions, endometriosis can be difficult to diagnose. As there currently are no accurate noninvasive diagnostic tests specific for endometriosis, it is imperative for the APN to become knowledgeable about the etiology, clinical presentation, diagnosis, and current treatment options of this disease. The APN in primary care plays an essential role in health promotion through disease management and infertility prevention by providing support and much needed information to the patient with endometriosis. APNs can also facilitate quality of care and manage treatments effectively to improve quality of life, reduce pain, and prevent further progression of disease. Practice recommendations include timely diagnosis, pain management, infertility counseling, patient education, and support for quality of life issues.

The Liaison Committee on Medical Education mandates a core curriculum in primary care but does not specify its content or structure. In this study, we explored the question of whether primary care specialty or geographic location affects student learning and satisfaction. From 1994 to 1996, 294 third-year medical students at one medical school in New York state were randomly assigned to multiple teaching sites for a required 5-week primary care clerkship. Independent predictor variables were primary care specialty of the preceptor (family medicine, medicine, pediatrics, or joint medicine and pediatrics) and geographic location of the site (urban, suburban, rural). Outcome measures included four areas of student satisfaction, one of patient volume, and two of student performance. Primary care specialty had no detectable association with the outcome measures, except for a lower rating of patient diversity in pediatric experiences (P <0.001). Geographic location of the site had a significant association with all measures of student satisfaction and patient volume (all P values <0.001). Students at rural sites rated the experience more highly and saw on average 15 more patients per rotation. Ratings of student satisfaction remained high after adjusting for patient volume. Primary care specialty and geographic location did not influence student performance in the clerkship or scores on standardized patient examination. Rural geographic location of teaching site, but not primary care specialty, was associated with higher student satisfaction. However, higher student satisfaction ratings did not correspond to better student performance. Provided that all sites meet the screening criteria for inclusion in a teaching program, these findings support the continued development of high-quality, heterogeneous, interdisciplinary, primary care experiences.

Alignment between Chronic Disease Policy and Practice: Case Study at a Primary Care Facility
Draper, Claire A.; Draper, Catherine E.; Bresick, Graham F.
2014-01-01
Background Chronic disease is by far the leading cause of death worldwide and of increasing concern in low- and middle-income countries, including South Africa, where chronic diseases disproportionately affect the poor living in urban settings. The Provincial Government of the Western Cape (PGWC) has prioritized the management of chronic diseases and has developed a policy and framework (Adult Chronic Disease Management Policy 2009) to guide and improve the prevention and management of chronic diseases at a primary care level. The aim of this study is to assess the alignment of current primary care practices with the PGWC Adult Chronic Disease Management policy. Methods One comprehensive primary care facility in a Cape Town health district was used as a case study. Data was collected via semi-structured interviews (n = 10), focus groups (n = 8) and document review. Participants in this study included clinical staff involved in chronic disease management at the facility and at a provincial level. Data previously collected using the Integrated Audit Tool for Chronic Disease Management (part of the PGWC Adult Chronic Disease Management policy) formed the basis of the guide questions used in focus groups and interviews. Results The results of this research indicate a significant gap between policy and its implementation to improve and support chronic disease management at this primary care facility. A major factor seems to be poor policy knowledge by clinicians, which contributes to an individual rather than a team approach in the management of chronic disease patients. Poor interaction between facility- and community-based services also emerged. A number of factors were identified that seemed to contribute to poor policy implementation, the majority of which were staff related and ultimately resulted in a decrease in the quality of patient care. Conclusions Chronic disease policy implementation needs to be improved in order to support chronic disease management at this facility. It is possible that similar findings and factors are present at other primary care facilities in Cape Town. At a philosophical level, this research highlights the tension between primary health care principles and a diseased-based approach in a primary care setting. PMID:25141191

Chronic kidney disease (CKD) is common and a significant marker of morbidity and mortality. Its management in primary care is essential for maintenance of cardiovascular health, avoidance of acute kidney injury (AKI) and delay in progression to end-stage renal disease. Although many guidelines and interventions have been established, there is global evidence of an implementation gap, including variable identification rates and low patient communication and awareness. The objective of this study is to understand the factors enabling and constraining the implementation of CKD interventions in primary care. A rapid realist review was conducted that involved a primary literature search of three databases to identify existing CKD interventions in primary care between the years 2000 and 2014. A secondary search was performed as an iterative process and included bibliographic and grey literature searches of reference lists, authors and research groups. A systematic approach to data extraction using Normalisation Process Theory (NPT) illuminated key mechanisms and contextual factors that affected implementation. Our primary search returned 710 articles that were narrowed down to 18 relevant CKD interventions in primary care. Our findings suggested that effective management of resources (encompassing many types) was a significant contextual factor enabling or constraining the functioning of mechanisms. Three key intervention features were identified from the many that contributed to successful implementation. Firstly, it was important to frame CKD interventions appropriately, such as within the context of cardiovascular health and diabetes. This enabled buy-in and facilitated an understanding of the significance of CKD and the need for intervention. Secondly, interventions that were compatible with existing practices or patients' everyday lives were readily accepted. In contrast, new systems that could not be integrated were abandoned as they were viewed as inconvenient, generating more work. Thirdly, ownership of the feedback process allowed users to make individualised improvements to the intervention to suit their needs. Our rapid realist review identified mechanisms that need to be considered in order to optimise the implementation of interventions to improve the management of CKD in primary care. Further research into the factors that enable prolonged sustainability and cost-effectiveness is required for efficient resource utilisation.

Indigenous populations have poorer health outcomes compared to their non-Indigenous counterparts. The evolution of Indigenous primary health care services arose from mainstream health services being unable to adequately meet the needs of Indigenous communities and Indigenous peoples often being excluded and marginalised from mainstream health services. Part of the solution has been to establish Indigenous specific primary health care services, for and managed by Indigenous peoples. There are a number of reasons why Indigenous primary health care services are more likely than mainstream services to improve the health of Indigenous communities. Their success is partly due to the fact that they often provide comprehensive programs that incorporate treatment and management, prevention and health promotion, as well as addressing the social determinants of health. However, there are gaps in the evidence base including the characteristics that contribute to the success of Indigenous primary health care services in providing comprehensive primary health care. This systematic scoping review aims to identify the characteristics of Indigenous primary health care service delivery models. This systematic scoping review was led by an Aboriginal researcher, using the Joanna Briggs Institute Scoping Review Methodology. All published peer-reviewed and grey literature indexed in PubMed, EBSCO CINAHL, Embase, Informit, Mednar, and Trove databases from September 1978 to May 2015 were reviewed for inclusion. Studies were included if they describe the characteristics of service delivery models implemented within an Indigenous primary health care service. Sixty-two studies met the inclusion criteria. Data were extracted and then thematically analysed to identify the characteristics of Indigenous PHC service delivery models. Culture was the most prominent characteristic underpinning all of the other seven characteristics which were identified - accessible health services, community participation, continuous quality improvement, culturally appropriate and skilled workforce, flexible approach to care, holistic health care, and self-determination and empowerment. While the eight characteristics were clearly distinguishable within the review, the interdependence between each characteristic was also evident. These findings were used to develop a new Indigenous PHC Service Delivery Model, which clearly demonstrates some of the unique characteristics of Indigenous specific models.

Determining the genetic basis of cancer requires comprehensive analyses of large collections of histopathologically well-classified primary tumours. Here we report the results of a collaborative study to discover somatic mutations in 188 human lung adenocarcinomas. DNA sequencing of 623 genes with known or potential relationships to cancer revealed more than 1,000 somatic mutations across the samples. Our analysis identified 26 genes that are mutated at significantly high frequencies and thus are probably involved in carcinogenesis. The frequently mutated genes include tyrosine kinases, among them the EGFR homologue ERBB4; multiple ephrin receptor genes, notably EPHA3; vascular endothelial growth factor receptor KDR; and NTRK genes. These data provide evidence of somatic mutations in primary lung adenocarcinoma for several tumour suppressor genes involved in other cancers—including NF1, APC, RB1 and ATM—and for sequence changes in PTPRD as well as the frequently deleted gene LRP1B. The observed mutational profiles correlate with clinical features, smoking status and DNA repair defects. These results are reinforced by data integration including single nucleotide polymorphism array and gene expression array. Our findings shed further light on several important signalling pathways involved in lung adenocarcinoma, and suggest new molecular targets for treatment. PMID:18948947

Women undergoing surgery for ovarian cancer are severely ill and are high users of health services. Contributing to these increased utilization rates are the multiple modalities used to treat ovarian cancer and the complications and side effects from those treatments. The purpose of this study was to evaluate the effectiveness of an intervention provided by advanced practice nurses and a psychiatric consultation-liaison nurse on patients' self-report of healthcare utilization compared with an attention control intervention in women undergoing surgery for a suspected diagnosis of ovarian cancer. A two-group, experimental, longitudinal design was used to compare women who were assigned randomly to the intervention group or to an attention control group at baseline within 48 hours after surgery and 1, 3, and 6 months after surgery. Healthcare utilization was measured as the number of self-reported inpatient admissions and outpatient visits, including emergency room visits, oncology outpatient visits, and primary care visits. Nurse interventions consisted of 16 contacts: symptom management, counseling, education, direct nursing care, coordination of resources, and referrals. The attention control interventions consisted of nine contacts that included instructions on use of a symptom management toolkit and strategies on how to manage symptoms. There were no differences in hospitalizations and oncology outpatient visits between the two groups. The main finding of this study was a significant difference in the number of primary care visits between the two groups. Women in the attention control group went to their primary care providers more often than the intervention group. The women who reported more visits also reported more depressive symptoms. In addition, a trend was found in the number of emergency room visits between the two groups. The intervention group visited the emergency room more often because the nurse instructed patients to go when they recognized symptoms that needed urgent care after hours. Women in the intervention group appropriately used the emergency room to manage their problems after hours, whereas more women in the attention control group reported significantly more primary care visits. These findings highlight the need for healthcare providers representing various disciplines to coordinate services across specialties, especially for women who have depressive symptoms.

Health services face the challenges created by complex problems, and so need complex intervention solutions. However they also experience ongoing difficulties in translating findings from research in this area in to quality improvement changes on the ground. BounceBack was a service development innovation project which sought to examine this issue through the implementation and evaluation in a primary care setting of a novel complex intervention. The project was a collaboration between a local mental health charity, an academic unit, and GP practices. The aim was to translate the charity's model of care into practice-based evidence describing delivery and impact. Normalisation Process Theory (NPT) was used to support the implementation of the new model of primary mental health care into six GP practices. An integrated process evaluation evaluated the process and impact of care. Implementation quickly stalled as we identified problems with the described model of care when applied in a changing and variable primary care context. The team therefore switched to using the NPT framework to support the systematic identification and modification of the components of the complex intervention: including the core components that made it distinct (the consultation approach) and the variable components (organisational issues) that made it work in practice. The extra work significantly reduced the time available for outcome evaluation. However findings demonstrated moderately successful implementation of the model and a suggestion of hypothesised changes in outcomes. The BounceBack project demonstrates the development of a complex intervention from practice. It highlights the use of Normalisation Process Theory to support development, and not just implementation, of a complex intervention; and describes the use of the research process in the generation of practice-based evidence. Implications for future translational complex intervention research supporting practice change through scholarship are discussed.

We sought to replicate findings about the effect of therapist-imposed structure on alcoholism-treatment effectiveness for aftercare patients at different levels of interpersonal reactance and to examine if the effect generalizes to patients in a primary phase of treatment. Analyses were based on ex post facto observer ratings combined with outcome data from a randomized clinical trial. Participants had alcohol abuse or dependence (N = 247) and received treatment at either a primary outpatient treatment site (n = 125) or an aftercare site (n = 122) of Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity). Patients' trait reactance and therapist structure were assessed via observer ratings based on videotaped therapy sessions. Dependent variables included percentage days abstinent, percentage heavy-drinking days, time to first drinking day, and time to first heavy-drinking day throughout a 1-year posttreatment period. The results indicated that increased therapist structure during aftercare treatment predicted fewer abstinent days and more heavy-drinking days for persons at a high level of reactance than for persons at a low level of reactance. The effect was a consistent predictor of alcohol use throughout each 3-month interval within the follow-up period. The interaction effect was not supported in the primary outpatient treatment sites, and it was not supported as a predictor of time to first drink or time to first heavy drink in either the aftercare or the outpatient sites. This study successfully replicated the finding that level of patient reactance appears to moderate the effect of therapist structure on alcohol-use outcomes in aftercare treatment settings. The lack of support for this effect in primary outpatient treatment settings suggests that the negative effect of structured treatment may be limited to patients who are further along in the recovery process.
