The impact of scientific articles is proportional to the citations they have received. In this study, the most cited works ("citation classics") related to Tourette syndrome (TS) were identified as articles with more than 100 citations according to the Web of Science. We retrieved 89 highly cited articles, which were published in 26 journals: 54 clinical studies, 27 laboratory studies, 7 reviews, and 1 classification article. Clinical studies consisted of phenomenologic evaluations of TS and comorbid behavioral problems (n = 22) and studies on pharmacotherapy (n = 16) and clinical genetics (n = 13), whereas laboratory studies covered basic genetics, cellular and molecular biology (n = 11), and neurobiology (neuroimaging, neuropathology, and neurophysiology) (n = 16). The majority (58%) of citation classics were published after 1990, when laboratory studies (especially neuroimaging, immunologic, and genetic studies) became widely cited. These articles are able to reach the highest numbers of citations in a short time span and suggest potential directions for future research.
BackgroundThe ‘weekend effect’ describes the phenomenon where patient outcomes appear worse for those admitted at the weekend. It has been used recently to justify significant changes in UK health policy. Recent evidence has suggested that the effect may be due to a combination of inadequate correction for confounding factors and inaccurate coding. The effects of these factors were investigated in patients with acute abdominal aortic aneurysm (AAA).MethodsPatients undergoing non‐elective AAA repair entered into the UK National Vascular Registry from January 2013 until December 2015 were included in a case–control study. The patients were divided according to whether they were treated during the week (Monday 08.00 hours to Friday 17.00 hours) or at the weekend. Data extracted included demographics, co‐morbidities, preoperative medications and baseline blood test results, as well as outcomes. Coding issues were investigated by looking at patients treated for ruptured, symptomatic or asymptomatic AAA within the non‐elective cohort. The primary outcome was in‐hospital mortality. Secondary outcomes included length of inpatient stay, and cardiac, respiratory and renal complications.ResultsThe mortality rate appeared to be higher at the weekend (odds ratio (OR) 1·69, 95 per cent c.i. 1·47 to 1·94; P < 0·001), but this effect disappeared when confounding factors and coding issues were corrected for (corrected OR for ruptured AAA 1·09, 0·92 to 1·29; P = 0·330). Differences in outcomes were similar for prolonged length of hospital stay (uncorrected OR 1·21, 95 per cent c.i. 1·06 to 1·37, P = 0·005; corrected OR for ruptured AAA 1·06, 0·91 to 1·10, P = 0·478), and morbidity outcomes.ConclusionAfter appropriate correction for confounding factors and coding effects, there was no evidence of a significant weekend effect in the treatment of non‐elective AAA in the UK.
Arterial calcification in different arterial beds has been observed to be an independent predictor of mortality. The association of abdominal visceral artery calcium with all-cause mortality remains unexplored. Patients who had undergone contrast-enhanced computerized tomography (CT) imaging for routine assessment of peripheral arterial disease (PAD) were considered for this study. A novel calcium score (abdominal visceral arteries calcium [AVAC]) for the abdominal visceral arteries (celiac axis, superior mesenteric, and renal arteries) was calculated using a modified Agatston score. Cumulative AVAC was defined as sum total of the calcium score of above individual arteries. The primary outcome was all-cause mortality. The association of AVAC with all-cause mortality was assessed. Of the 134 consecutive patients, 89 were included for analysis. Median follow-up duration was 72 (47-91) months since CT imaging; 35 (39%) patients died during this period. Hypertension and cumulative AVAC score had a significant association with all-cause mortality ( P < .05). Cumulative visceral abdominal artery calcification is associated with all-cause mortality in patients with PAD. Future prospective studies are warranted to investigate this relationship in PAD and other patient cohorts.
PURPOSE Bladder-sparing trimodal therapy (TMT) is an alternative to radical cystectomy (RC) according to international guidelines. However, there are limited data to guide management of nonmetastatic clinically node-positive bladder cancer (cN+ M0 BCa). We performed a multicenter retrospective analysis of survival outcomes in node-positive patients to inform practice. METHODS Data from patients diagnosed with cN+ M0 BCa were collected from participating UK Oncology centers offering both TMT and RC. Overall survival (OS) and progression-free survival (PFS) outcomes were collected with details of treatment and clinical factors. RESULTS A total of 287 patients with cN+ M0 BCa were included in the survival analysis. Median OS across all patients was 1.55 years (95% CI, 1.35 to 1.82 years). Receiving radical treatments was associated with improved OS (hazard ratio [HR], 0.32; 95% CI, 0.23 to 0.44; P < .001) compared with receiving palliative treatment. Radically treated patients (n = 163) received RC (n = 76) or radical dose radiotherapy (RT, n = 87); choice of radical treatment showed no association with OS (HR, 0.94; 95% CI, 0.63 to 1.41; P = .76) or PFS (HR, 0.74; 95% CI, 0.50 to 1.08; P = .12) on multivariable analysis. CONCLUSION Patient cohorts with cN+ M0 BCa had equivalent survival outcomes whether treated with surgery or radical RT. Given the known morbidities of RC—in a patient group with poor survival—this study confirms that bladder-sparing TMT treatment should be a treatment option available to all patients with cN+ M0 BCa.
Background Many central initiatives to improve digital maturity and interoperability in the NHS started after 2015. There are few prior assessments of digital maturity and interoperability. Methods Freedom of Information Act requests were sent to all English Acute NHS Trusts and Clinical Commissioning Groups (CCGs) to obtain information regarding digital maturity according to the Healthcare Information and Management Systems Society (HIMSS) Electronic Medical Record Adoption Mode (EMRAM) scale, and interoperability. Results One third of Acute NHS Trusts have an EMR that meets requirements for EMRAM stage 6 or above. 17.4% of responding Trusts considered this. 59.1% of responding Trusts stated that their EMR allows for functional interoperability with other (interoperable) EMRs. The majority of responding Trusts had not conferred with other Trusts when making EMR purchasing decisions. Discussion In order to realise the benefits of digitisation and interoperability, we discuss policy recommendations including actions for local health economies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
