- OBJECTIVE: To identify subgroups of patients with work-related back pain based on disability risk factors. METHODS: Patients with work-related back pain (N = 528) completed a 16-item questionnaire of potential disability risk factors before their initial medical evaluation. Outcomes of pain, functional limitation, and work disability were assessed 1 and 3 months later. RESULTS: A K-Means cluster analysis of 5 disability risk factors (pain, depressed mood, fear avoidant beliefs, work inflexibility, and poor expectations for recovery) resulted in 4 sub-groups: low risk (n = 182); emotional distress (n = 103); severe pain/fear avoidant (n = 102); and concerns about job accommodation (n = 141). Pain and disability outcomes at follow-up were superior in the low-risk group and poorest in the severe pain/fear avoidant group. CONCLUSIONS: Patients with acute back pain can be discriminated into subgroups depending on whether disability is related to pain beliefs, emotional distress, or workplace concerns

- OBJECTIVES: The aim of the study was to investigate the prevalence of orofacial pain (OFP) among young adults (30-31 years old) and to determine the effect of childhood and adulthood risk factors on the occurrence of OFP. METHODS: Prospective cohort study to investigate dental and social effects of malocclusion and effectiveness of orthodontic treatment was conducted in Wales, United Kingdom. At 20-year follow-up 337 subjects aged 30-31 participated (74% from previous follow-up aged 19-20 and 33% from the baseline) and were asked about OFP. RESULTS: The prevalence of OFP was 23% (95% CI: 19%, 28%). Childhood factors, socio-demographic, lifestyle, health behavior factors, history of orthodontic treatment and tooth wear were not associated with OFP. Participants with OFP were more likely to report that their teeth did not fit together properly [odds ratio (OR) = 12.4, 95% CI: 2.7-56.5) and reported previous trauma to the jaws (2.3; 1.3-4.2). Both diurnal and nocturnal teeth clenching and grinding were significantly associated with OFP (3.1; 1.4-7.1). Participants with frequent headaches had increased risk of having OFP (3.7; 1.6-8.4) while having reported 4-10 types of pain in other parts of the body other than the head, was associated with OR = 9.2 (3.7-23.0). An increased tendency to have OFP was seen in those individuals with higher levels of psychological distress (2.3; 1.4-3.9), high score on Life Event Inventory (2.6; 1.3-5.3), depressive symptoms (2.2; 1.2-4.0) and stress (2.2; 1.2-4.0). High self-esteem associated with lower risk of OFP (0.5; 0.3-0.9). CONCLUSIONS: This study shows that OFP is frequently reported by young adults aged 30-31 and supports a multifactorial etiology with factors from many domains, including local mechanical factors, psychological and co-morbidities. However, none of the childhood factors considered in this study were associated with OFP in adulthood.

- OBJECTIVE: Develop a cerebrospinal fluid biomarker signature for mild Alzheimer's disease (AD) in Alzheimer's Disease Neuroimaging Initiative (ADNI) subjects. METHODS: Amyloid-beta 1 to 42 peptide (A beta(1-42)), total tau (t-tau), and tau phosphorylated at the threonine 181 were measured in (1) cerebrospinal fluid (CSF) samples obtained during baseline evaluation of 100 mild AD, 196 mild cognitive impairment, and 114 elderly cognitively normal (NC) subjects in ADNI; and (2) independent 56 autopsy-confirmed AD cases and 52 age-matched elderly NCs using a multiplex immunoassay. Detection of an AD CSF profile for t-tau and A beta(1-42) in ADNI subjects was achieved using receiver operating characteristic cut points and logistic regression models derived from the autopsy-confirmed CSF data. RESULTS: CSF A beta(1-42) was the most sensitive biomarker for AD in the autopsy cohort of CSF samples: receiver operating characteristic area under the curve of 0.913 and sensitivity for AD detection of 96.4%. In the ADNI cohort, a logistic regression model for A beta(1-42), t-tau, and APO epsilon 4 allele count provided the best assessment delineation of mild AD. An AD-like baseline CSF profile for t-tau/A beta(1-42) was detected in 33 of 37 ADNI mild cognitive impairment subjects who converted to probable AD during the first year of the study. INTERPRETATION: The CSF biomarker signature of AD defined by A beta(1-42) and t-tau in the autopsy-confirmed AD cohort and confirmed in the cohort followed in ADNI for 12 months detects mild AD in a large, multisite, prospective clinical investigation, and this signature appears to predict conversion from mild cognitive impairment to AD.

- OBJECTIVE: To develop a consensus plan for research and practice to encourage routine clinician screening of occupational factors associated with long-term back disability.METHODS: A 3-day conference workshop including 21 leading researchers and clinicians (the "Decade of the Flags Working Group") was held to review the scientific evidence concerning clinical, occupational, and policy factors in back disability and the development of feasible assessment and intervention strategies.RESULTS: The Working Group identified seven workplace variables to include in early screening by clinicians: physical job demands, ability to modify work, job stress, workplace social support or dysfunction, job satisfaction, expectation for resuming work, and fear of re-injury. Five evaluation criteria for screening methods were established: reliability, predictive performance, feasibility, acceptability, and congruence with plausible interventions. An optimal screening method might include a stepped combination of questionnaire, interview, and worksite visit. Future research directions include improving available assessment methods, adopting simpler and more uniform conceptual frameworks, and tying screening results to plausible interventions.DISCUSSION:There is a clear indication that occupational factors influence back disability, but to expand clinician practices in this area will require that patient screening methods show greater conceptual clarity, feasibility, and linkages to viable options for intervention.
