BACKGROUND: Given the safety concerns regarding pharmacological agents, and the considerable impact of headache and migraine on the sufferer's quality of life, many people seek other treatment options beyond conventional medication and care to address their symptoms; this includes complementary and alternative medicine (CAM). Some CAM interventions have shown promising results in clinical trials of headache and migraine management. Nonetheless, there has been little research exploring the reasons for using CAM, and the types of CAM used, among this population...

AIMS: Heart failure with a preserved ejection fraction (HF-PEF) remains a difficult clinical diagnosis. The aim of this study was to test the utility of established criteria to classify patients with HF-PEF. We prospectively enrolled patients into one of five groups across a spectrum of cardiac disease and applied three different criteria for HF-PEF and calculated diagnostic metrics. METHODS AND RESULTS: A total of 565 patients were included in the analysis, including 170 patients with an adjudicated diagnosis of HF-PEF, 152 patients with heart failure with reduced ejection fraction, 152 patients at risk for heart failure, and 91 age-matched healthy controls...

BACKGROUND: Clinical data that support stereotactic body radiation therapy (SBRT) metastatic malignant melanoma (MM) are limited. Furthermore, functional imaging with 18F-fludeoxyglucose positron emission tomography (PET) may offer a more accurate post-SBRT assessment. Therefore, we assessed the clinical outcomes and metabolic response of metastatic MM after SBRT. METHODS AND MATERIALS: Patients with MM who were treated with SBRT and had pre- and post-PET scans (>1) were included in this study...

Surveillance at an abattoir allows all animals or carcasses that present a potential public health risk to be withdrawn from the human food chain. Whole-carcass condemnation results in important economic losses, not only for the producer but also for other participants in the meat industry. Access to the personal electronic database of an abattoir in France enabled us to run logistic regression models to investigate the risk factors for whole-carcass condemnation of end-cycle sows in that abattoir. When end-cycle sows that were slaughtered and eviscerated between 22 June 2015 and 8 December 2015 (185 days) were considered (n = 19,866), the results highlighted the importance of the total theoretical time off feed, which represents the fasting period from leaving the farm of origin to the time of slaughter (including transportation and waiting time at the abattoir)...

BACKGROUND: Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys are used to assess the quality of the patient experience following an inpatient stay. HCAHPS scores are used to determine reimbursement for hospital systems and incentivize spine surgeons nationwide. There are conflicting data detailing whether early readmission or other post-discharge complications are associated with patient responses on the HCAHPS survey. Currently, the association between post-discharge ED visits and HCAHPS scores following lumbar spine surgery is unknown...

BACKGROUND CONTEXT: Nerve root compression causing symptomatic radiculopathy can occur within the intervertebral foramen. Sagittal MRI sequences are reliable in detection of nerve root contact to intraforaminal disc material, but a clinically relevant classification of degree of contact is lacking. PURPOSE: To investigate a potential relation of amount of contact between intraforaminal disc material and nerve root to clinical findings and response after periradicular corticosteroid infiltration...

BACKGROUND: Severe aorto-iliac occlusive disease (AIOD) is traditionally treated with aorto-bifemoral (ABF) or aorto-unifemoral (AUF) bypass. However, cross-femoral bypass (CFB) and hybrid femoral endarterectomy and patch angioplasty with iliac stenting (EPS) have gained popularity as less invasive options. We sought to compare 1-year survival, primary patency, and major amputation rates between open surgical (ABF and AUF) and two less invasive reconstruction techniques (CFB and EPS) using a large, multicenter cohort...

BACKGROUND: Although a number of studies have examined the relationship between depression and obesity, it is still insufficient to establish the specific pattern of relationship between depression and body mass index (BMI) categories. Thus, this study was aimed to investigate the relationship between depression and BMI categories. METHODS: A cross-sectional study was conducted for a cohort of 159,390 Korean based on Kangbuk Samsung Health Study (KSHS). Study participants were classified into 5 groups by Asian-specific cut-off of BMI (18...

OBJECTIVE: Vehicle crashes which involved pedestrian at intersections have been reported occasionally. The injury severity of pedestrians in these crashes seems significantly related to driver and pedestrian attributes, vehicle characteristics, and the geometry of intersections. Identifying factors associated with pedestrian injury severity (PIS) is critical for reducing crashes and improving safety. For developing the proposed probit models, drivers who involved crashes are classified into three groups: young drivers (16 ≤ age ≤ 24); middle-aged drivers (25 ≤ age ≤ 64); older drivers (age ≥ 65)...

Scatter correction is typically done using a simulation of the single scatter, which is then scaled to account for multiple scatters and other possible model mismatches. This scaling factor is determined by fitting the simulated scatter sinogram to the measured sinogram, using only counts measured along LORs that do not intersect the patient body, i.e. 'scatter-tails'. Extending previous work, we propose to scale the scatter with a plane dependent factor, which is determined as an additional unknown in the maximum likelihood (ML) reconstructions, using counts in the entire sinogram rather than only the 'scatter-tails'...

Compared to other forensic comparative sciences, studies of the efficacy of the likelihood ratio (LR) framework in forensic authorship analysis are lagging. An experiment is described concerning the estimation of strength of linguistic text evidence within that framework. The LRs were estimated by trialling three different procedures: one is based on the multivariate kernel density (MVKD) formula, with each group of messages being modelled as a vector of authorship attribution features; the other two involve N-grams based on word tokens and characters, respectively...

BACKGROUND: There is a need for a better understanding of the role of C-reactive protein (CRP) as a valid marker for the detection of bacterial infections in critically immunosuppressed patients. A high negative predictive value of CRP is also needed to rule out sepsis and bacterial infections in immunocompetent patients. However, few studies have evaluated the performance of CRP in immunocompromised hosts. The aim of the present study was to evaluate the performance of CRP as a marker of infection in critically immunosuppressed patients...

BACKGROUND: Whereas several studies suggest that high-volume surgeons and hospitals deliver superior patient outcomes with greater cost efficiency, no evidence-based thresholds separating high-volume surgeons and hospitals from those that are low or medium volume exist in shoulder arthroplasty. The objective of this study was to establish meaningful thresholds that take outcomes and cost into consideration for surgeons and hospitals performing shoulder arthroplasty. METHODS: Using 9546 patients undergoing primary shoulder arthroplasty for osteoarthritis from an administrative database, we created and applied 4 models using stratum-specific likelihood ratio (SSLR) analysis of a receiver operating characteristic (ROC) curve...

BACKGROUND: Headache is a common disorder which may lead to substantial socio-economic loss. Treatment options include self-management strategies, medication and physiotherapy. Physiotherapists need to be able to screen for the presence of migraine and tension-type headache (TTH), so they can adjust their treatment strategies to the type of headache. A quick screening questionnaire to recognize migraine and TTH in the physiotherapy practice is needed. OBJECTIVE: The aim of this study was to create a headache screening questionnaire based on the ICHD-3 beta criteria for migraine and TTH, and to establish its content and criterion validity...
