For the diagnosis of systemic autoimmune rheumatic diseases (SARD), patients are screened for anti-nuclear antibodies (ANA). ANA, as assessed by indirect immunofluorescence (IIF), have a poor specificity. This hampers interpretation of positive results in clinical settings with low pretest probability of SARD. We hypothesized that the utility of positive ANA IIF results increases from primary to tertiary care. We retrospectively determined ANA, anti-ENA, and anti-dsDNA antibody prevalence in patient cohorts from primary (n=1453), secondary (n=1621), and tertiary (n=1168) care settings. Results reveal that from primary care to tertiary care, ANA prevalence increases (6.2, 10.8, and 16.0%, resp.). Moreover, in primary care low titres (70% versus 51% and 52% in secondary and tertiary care, resp.) are more frequent and anti-ENA/dsDNA reactivities are less prevalent (21% versus 39% in secondary care). Typically, in tertiary care the prevalence of anti-ENA/dsDNA reactivities (21%) is lower than expected. From this descriptive study we conclude that positive ANA IIF results are more prone to false interpretation in clinical settings with low pretest probabilities for SARD, as in primary care. Whether alternative approaches, that is, immunoadsorption of anti-DFS70 antibodies or implementation of anti-ENA screen assays, perform better, needs to be determined.

ABSTRACT Highly specific borreliacidal antibodies are induced by infection with Borrelia burgdorferi, and a borreliacidal antibody test (BAT) may be an accurate laboratory procedure for confirming Lyme disease in clinical practice. To investigate this, 34 Lyme disease sera and 34 sera from patients with other illnesses who had presented to a primary-care facility located in an area of borreliosis endemicity were tested by the BAT and Western blotting (WB). The BAT was more sensitive (79% versus 65%; P = 0.090), especially in cases in which patients had a single erythema migrans lesion (P = 0.021). In addition, the potentially cross-reactive sera were negative by the BAT but WB yielded three (9%) false-positive results. The results from 104 sera from possible Lyme disease patients demonstrated the clinical usefulness of the more sensitive and specific BAT. The BAT was positive for 40 (38%) sera from patients with Lyme disease-related symptoms and appropriate clinical and epidemiological findings. WB confirmed Lyme disease in 30 (75%) of the 40 BAT-positive patients but failed to detect B. burgdorferi infection in 10 BAT-positive patients. WB was also positive for 11 BAT-negative sera, but six (55%) patients had case histories which suggested that the results were false positives. Collectively, the results confirm that the BAT is a sensitive and highly specific test and suggest that widespread use would increase the accuracy of serodiagnostic confirmation of Lyme disease.

Two distinct clusters of gastroenteritis due to Salmonellae and Entamoeba histolytica (EH) were identified using a multiplex gastrointestinal pathogen panel (GPP) at a tertiary-care cancer center. Despite temporo-spatial overlap, our investigation did not corroborate transmission or true infection. In clinical practice, GPPs may render false-positive results.Infect Control Hosp Epidemiol 2018;867–870

ABSTRACT Intracranial vessel wall imaging plays an increasing role in diagnosing intracranial vascular diseases. With the growing demand and subsequent increased use of this technique in clinical practice, radiologists and neurologists should be aware of the choices in imaging parameters and how they affect image quality, clinical indications, methods of assessment, and limitations in the interpretation of these images. Due to the improvement of the MRI techniques, the possibility of accurate and direct evaluation of the abnormalities in the arterial vascular wall (vessel wall imaging) has evolved, adding substantial data to diagnosis when compared to the indirect evaluation based on conventional flow analyses. Herein, the authors proposed a comprehensive approach of this technique reinforcing appropriated clinical settings to better use intracranial vessel wall imaging.

We compared the work settings and “community-oriented clinical practice” of Community Medicine (CM) specialists and family physicians/general practitioners (FP). We conducted secondary data analysis of the 2004 National Physician Survey (NPS) to examine main work setting and clinical activity reported by 154 CM (40% of eligible CM in Canada) and 11,041 FP (36% of eligible FP in Canada). Text data from the specialist questionnaire related to “most common conditions that you treat” were extracted from the Master database for CM specialists, and subjected to thematic analysis and coded. CM specialists were more likely than FP to engage in “community medicine/public health” (59.7% vs 15.3%); while the opposite was found for primary care (13% vs. 78.2%). CM specialists were less likely to indicate a main work setting of private office/clinic/community health centre/community hospital than were FP (13.6% vs. 75.6%). Forty-five percent of CM provided a response to “most common conditions treated” with the remainder either leaving the item blank or indicating that they did not treat individual patients. The most frequently named conditions in rank order were: psychiatric disorders; public health program/activity; respiratory problems; hypertension; and metabolic disorders (diabetes). There is some overlap in the professional activities and work settings of CM specialists and FP. The “most commonly treated conditions” suggest that some CM specialists may be practicing primary care as part of the Royal College career path of “community-oriented clinical practice.” However the “most commonly treated conditions” do not specifically indicate an orientation of that practice towards “an emphasis on health promotion and disease prevention” as also specified by the Royal College for that CM career path. This raises questions about the appropriateness of the current training requirements and career paths as delineated for CM specialists by the Royal College of Physicians & Surgeons of Canada.

The “disconnect” between the body of knowledge acquired in classroom settings and the application of this knowledge in clinical practice is one of the main reasons for professional fear, anxiety and feelings of incompetence among freshly graduated nurses. While the phenomenon of the theory-to-practice gap has been researched quite extensively in high-income country settings much less is known about nursing students’ experiences in a developing country context. To rectify this shortcoming, the qualitative study investigated the experiences of nursing students in their attempt to apply what they learn in classrooms in clinical learning contexts in seven sites in Nigeria. Thematic content analysis was used to analyse data gained from eight focus group discussions (n = 80) with the students. The findings reveal a multifaceted theory-practice gap which plays out along four tensions: (1) procedural, i.e. the difference between practices from education institutions and the ones enacted in clinical wards – and contradictions that emerge even within one clinical setting; (2) political, i.e. conflicts that arise between students and clinical staff, especially personnel with a lower qualification profile than the degree that students pursue; (3) material, i.e. the disconnect between contemporary instruments and equipment available in schools and the lack thereof in clinical settings; and (4) temporal, i.e. restricted opportunities for supervised practice owing to time constraints in clinical settings in which education tends to be undervalued. Many of these aspects are linked to and aggravated by infrastructural limitations, which are typical for the setting of a developing country. Nursing students need to be prepared regarding how to deal with the identified procedural, political, material and temporal tensions before and while being immersed in clinical practice, and, in so doing, they need to be supported by educationally better qualified clinical staff.

BackgroundThe WikiRecs evidence summaries and recommendations for clinical practice are developed using trustworthy methods. The process is triggered by studies that may potentially change practice, aiming at implementing new evidence into practice fast.AimTo share our first experiences developing WikiRecs for primary care and to reflect on the possibilities and pitfalls of this method.MethodIn March 2017, we started developing WikiRecs for primary health care to speed up the process of making potentially practice-changing evidence in clinical practice. Based on a well-structured question a systematic review team summarises the evidence using the GRADE approach. Subsequently, an international panel of primary care physicians, methodological experts and patients formulates recommendations for clinical practice. The patient representatives are involved as full guideline panel members. The final recommendations and supporting evidence are disseminated using various platforms, including MAGICapp and scientific journals.ResultsWe are developing WikiRecs on two topics: alpha-blockers for urinary stones and supervised exercise therapy for intermittent claudication. We did not face major problems but will reflect on issues we had to solve so far. We anticipate having the first WikiRecs for primary care available at the end of 2017.ConclusionThe WikiRecs process is a promising method — that is still evolving — to rapidly synthesise and bring new evidence into primary care practice, while adhering to high quality standards.

In addition to the delivery of primary care services, recent changes to the NHS in the United Kingdom have placed increasing responsibility on GPs for the commissioning of the full range of health services from prevention through to clinical interventions and rehabilitation. Whilst historically there has always been an expectation that primary care professionals were ideally placed to provide support for prevention as well as treatment, their active engagement in the promotion of physical activity has remained largely superficial. With notable exceptions where individuals have a personal interest or commitment, the majority of health professionals tend to limit themselves to peremptory non-specific advice at best, or frequently don’t broach the subject at all. There are a number of reasons for this including increasing time pressures, a general lack of knowledge, limited evidence and concerns about litigation in the event of an adverse exercise induced event. However in the 1990s there was a surge of interest in the emerging “Exercise on Prescription” model where patients could be referred to community based exercise instructors for a structured “prescription” of exercise in community leisure centres. Despite the continuing popularity of the model there remain problems particularly in getting the active support of health professionals who generally cite the same barriers as previously identified. In an attempt to overcome some of these problems Wales established a national exercise referral scheme with an associated randomised controlled trial. The scheme evaluated well and had subsequently evolved with new developments including integration with secondary and tertiary care pathways, accredited training for exercise instructors and exit routes into alternative community based exercise opportunities.
