Objectives We propose new classification criteria for Sjögren’s Syndrome (SS), which are needed considering the emergence of biological agents as potential treatments and their associated co-morbidity. These criteria target individuals with signs/symptoms suggestive of SS. Methods Criteria are based on expert opinion elicited using the Nominal Group Technique, and analyses of data from the Sjögren’s International Collaborative Clinical Alliance. Preliminary criteria validation included comparisons with classifications based on the American-European-Consensus-Group (AECG) criteria, a model-based “gold standard” obtained from Latent Class Analysis (LCA) of data from a range of diagnostic tests, and a comparison with cases and controls collected from sources external to the population used for criteria development Results Validation results indicate high levels of sensitivity and specificity for the criteria. Case definition requires at least 2 out of the following 3: Positive serum anti-SSA and/or anti-SSB or [positive rheumatoid factor and ANA ≥ 1:320]; Ocular staining score ≥ 3; Presence of focal lymphocytic sialadenitis with focus score ≥ 1 focus/4mm2 in labial salivary gland biopsies. Observed agreement with the AECG criteria is high when these are applied using all objective tests. However, AECG classification based on allowable substitutions of symptoms for objective tests results in poor agreement with the proposed and LCA-derived classifications. Conclusion These classification criteria developed from registry data collected using standardized measures are based on objective tests. Validation indicates improved classification performance relative to existing alternatives, making them more suitable for application in situations where misclassification may present health risks.

Introduction Acute medication overuse is prevalent in patients with migraine. Methods In three phase 3, double-blind, randomized, placebo-controlled studies, patients with episodic migraine (EVOLVE-1 and EVOLVE-2) or chronic migraine (REGAIN) were randomized 2:1:1 to monthly subcutaneous injections of placebo or galcanezumab 120 or 240 mg for 3 or 6 months. This subgroup analysis evaluated mean changes in the number of monthly migraine headache days in each treatment among patients with versus without baseline acute medication overuse via mixing modelling with repeated measures. Results The percentages of patients with baseline medication overuse in placebo, galcanezumab 120-mg and 240-mg groups, respectively, were 19.4%, 17.3%, and 19.3% for EVOLVE-1/-2 (pooled; post hoc), and 63.4%, 64.3%, and 64.1% for REGAIN ( a priori). Both galcanezumab doses demonstrated significant improvement compared with placebo for overall least squares mean change in monthly migraine headache days in patients with baseline medication overuse in both the episodic and chronic migraine studies ( p ≤ 0.001). Furthermore, both galcanezumab doses reduced average monthly medication overuse rates compared to placebo ( p < 0.001) in both patient populations with medication overuse at baseline. Conclusions Galcanezumab appears to be effective for the preventive treatment of episodic and chronic migraine in patients who overuse acute medications.

Objective The aim was to assess diagnostic accuracy of 15 shoulder special tests for rotator cuff tears. Design From 02/2011 to 12/2012, 208 participants with shoulder pain were recruited in a cohort study. Results Among tests for supraspinatus tears, Jobe’s test had a sensitivity of 88% (95% CI=80% to 96%), specificity of 62% (95% CI=53% to 71%), and likelihood ratio of 2.30 (95% CI=1.79 to 2.95). The full can test had a sensitivity of 70% (95% CI=59% to 82%) and a specificity of 81% (95% CI=74% to 88%). Among tests for infraspinatus tears, external rotation lag signs at 0° had a specificity of 98% (95% CI=96% to 100%) and a likelihood ratio of 6.06 (95% CI=1.30 to 28.33), and the Hornblower’s sign had a specificity of 96% (95% CI=93% to 100%) and likelihood ratio of 4.81 (95% CI=1.60 to 14.49). Conclusions Jobe’s test and full can test had high sensitivity and specificity for supraspinatus tears and Hornblower’s sign performed well for infraspinatus tears. In general, special tests described for subscapularis tears have high specificity but low sensitivity. These data can be used in clinical practice to diagnose rotator cuff tears and may reduce the reliance on expensive imaging.
BackgroundPatients with higher socioeconomic status (SES) are shown to have better total knee arthroplasty (TKA) outcomes compared to those with lower SES. The relationship between SES and factors that influence TKA use is understudied. We examined the association between SES and pain, function and pain catastrophizing at presentation for TKA.MethodsIn patients undergoing TKA at an academic center, we obtained preoperative pain and functional status (WOMAC Index 0–100, 100 worst), pain catastrophizing (PCS, ≥16 high), and mental health (MHI-5, <68 poor). We described individual-level SES using education as a proxy, and area-level SES using a validated composite index linking geocoded addresses to U.S. Census data. We measured associations between these indicators and pain, function and pain catastrophizing, adjusting for age, sex and BMI.ResultsAmong 316 patients, mean age was 65.9 (SD 8.7), 59% were female, and 88% were Caucasian; 17% achieved less than college education and 62% were college graduates. The median area SES index score was 59 (U.S. median 51). Bivariable analyses demonstrated associations between higher individual- and area-level SES and lower pain, higher function and less pain catastrophizing (all p<0.05). Adjusted analyses demonstrated statistically significant associations between higher individual- and area-level SES and better function and less pain.ConclusionIn this cohort, patients with higher individual- and area-level SES had lower pain and higher function at the time of TKA than lower SES patients. Further research is needed to assess what constitutes appropriate levels of pain and function to undergo TKA in these higher SES groups.Electronic supplementary materialThe online version of this article (doi:10.1186/s12891-015-0475-8) contains supplementary material, which is available to authorized users.
Background:Structural characteristics of rotator cuff tears are used in surgical decision making. However, data on the association of tear size with patient-reported pain and function are sparse.Purpose:To assess the association of tear size, fatty infiltration, and muscle atrophy with shoulder pain/function in patients with cuff tears undergoing operative and nonoperative treatment.Study Design:Cross-sectional study; Level of evidence, 3.Methods:A total of 67 patients with rotator cuff tears were recruited for this longitudinal cohort study. Patients were determined to have a cuff tear using clinical assessment and blinded magnetic resonance imaging review. The Shoulder Pain and Disability Index (SPADI) was used as a measure of shoulder pain and function.Results:Tear size and thickness were not significantly associated with pain (SPADI pain score, 60.6 [95% CI, 49.8-71.5] for partial-thickness tear; 56.8 [95% CI, 42.8-70.7] for <2 cm full-thickness tear; 60.4 [95% CI, 51.7-69.0] for ≥2 cm full-thickness tear). Tear size and thickness were not associated with function (SPADI disability score, 42.7 [95% CI, 29.8-55.6] for partial-thickness tear; 37.6 [95% CI, 23.9-51.4] for <2 cm full-thickness tear; 45.1 [95% CI, 35.4-54.8] for ≥2 cm full-thickness tear). Fatty infiltration, muscle atrophy, and tendon retraction were also not significantly associated with SPADI pain and disability scores. A Mental Health Index score of <68 as well as age ≥60 years were significantly associated with a higher SPADI pain score. Female sex, increased number of comorbidities, Mental Health Index score of <68, and age <60 years were significantly associated with a higher SPADI disability score.Conclusion:In patients with rotator cuff tears undergoing operative and nonoperative treatment, pain and functional status were not associated with tear size and thickness, fatty infiltration, and muscle atrophy. Conversely, factors unrelated to cuff anatomy such as mental health, comorbidities, age, and sex were associated with pain/function. These findings have clinical implications during surgical decision making and suggest that pain and functional disability in patients with rotator cuff tears is multifactorial and should not solely be attributed to structural characteristics.
BackgroundSudden cardiac deaths have become a growing major public health concern that affects the world. Despite the various etiologies, life-threatening cardiac arrhythmias attribute the main cause of sudden cardiac deaths. Therefore in certain groups of high-risk patients, the Implantable Cardioverter Defibrillator (ICD) has been recommended as either a secondary or primary prophylactic method of prevention.ObjectiveTo summarise the perceptions of ICD recipients and provide an overview of their experiences with regards to the quality of life, coping strategies, and learning needs.MethodsA systematic search was conducted using CINAHL, MEDLINE, PsycINFO, Scopus, Cochrane Library, and Web of Science. Primary research articles published from January 2005 to January 2016 that met the inclusion criteria were selected and assessed for methodological quality.ResultsThirty-nine articles consisting of 16 qualitative studies, 22 quantitative studies, and 1 mixed methods study were included for the meta-synthesis. Findings extracted from these studies were grouped into eight subthemes with ‘living the ICD experience: a constant process of redefining oneself’ emerging as an over-arching theme.ConclusionThis review provides insight into the perspectives and experiences of ICD recipients. Current evidence highlights the need for healthcare professionals to improve future care standards and develop a patient-centric holistic program that meets the specific needs of ICD recipients. Moreover, future studies are required to address the research gaps identified and also explore the perceptions of patients living with ICD in the Asian context.
