Curt Hagquist, David Andrich
BACKGROUND: Rasch analysis with a focus on Differential Item Functioning (DIF) is increasingly used for examination of psychometric properties of health outcome measures. To take account of DIF in order to retain precision of measurement, split of DIF-items into separate sample specific items has become a frequently used technique. The purpose of the paper is to present and summarise recent advances of analysis of DIF in a unified methodology. In particular, the paper focuses on the use of analysis of variance (ANOVA) as a method to simultaneously detect uniform and non-uniform DIF, the need to distinguish between real and artificial DIF and the trade-off between reliability and validity...

Neha Goel, Sanjay S Reddy
The management of pancreatic cancer has grown rapidly in the last decade. The Gastrointestinal Tumor Study Group trial in 1985 supported postoperative chemoradiation, and a more recent study recommended 6 months of adjuvant gemcitabine and capecitabine or monotherapy with gemcitabine or fluorouracil plus folinic acid, in the absence of neoadjuvant therapy. Clinicians are now studying the role of targeted therapy in pancreatic cancer and neoadjuvant chemotherapy in resectable, borderline resectable, and locally advanced pancreatic cancer...

This article analyses the relationship between government spending and the distribution of private income between capital and labour. While most previous research assumes that government spending redistributes in favour of the less wealthy, I distinguish between types of expenditures that enhance the bargaining position of labour - that is, unemployment benefits, public sector employment and investment in new capital - and labour-saving and pro-business types of expenditures - that is, outsourcing to private firms...

BACKGROUND: Although Roux-en-Y gastric bypass (RYGB) induces short-term weight loss and co-morbidity amelioration, long-term data suggest that a subset of patients return to their preoperative body mass index (BMI). OBJECTIVES: To identify the clinical implications of 10-year weight loss failure after RYGB. SETTING: An academic teaching hospital. METHODS: Adults undergoing RYGB (1985-2004) were included in this study (n = 1087)...

High-quality data are critical for validly monitoring progress toward global initiatives related to road traffic crash prevention. We assessed the availability and consistency of road traffic mortality data from health and non-health departments in national governments, plus changes in data consistency over time from 1985 to 2013. Using freely accessible data, we systematically assessed availability and consistency of health and non-health data from 1985 to 2013 in 195 countries. Data availability was reflected by the presence of data on motor vehicle mortality rates in that country at any points between 1985 and 2013...

The Western Ghats (WG) of India are basically north-south oriented mountains having narrow zonal width with a steep rising western face. The summer monsoon winds during June to September passing over the Arabian Sea are obstructed by the WG and thus orographically uplift to produce moderate-to-heavy precipitation over the region. However, it is seen that characteristic features of rainfall distribution during the season vary from north to south. Also its correlation with all-India summer monsoon rainfall increases from south to north...

Records of the ocean sunfish Mola mola along the Norwegian coast were compiled from all possible sources: literature, media, databases and museums. A total of 216 records were found between 1801 and 2015. They were distributed along the whole coast, except for the most north-eastern part. Nearly all years with more than five records were after 2000, with 1985 as the only exception and with a maximum of 23 records in 2014. Most, 92·4%, were from July to December. Records from before 1979 were more incidental and random and no sunfish were recorded in 54 separate years between 1879 and 2015...

Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas. Myoepithelioma is usually a benign tumor arising from neoplastic myoepithelial or basket cells which are found between the basement membrane and the basal plasma membrane of acinar cells. They also contain multiple cellular elements. We present a case of a 73-year-old female with myoepithelioma of the parotid gland, an extremely rare neoplasm...

abstract James E. Webb, NASA's Administrator during the hectic years preparing to send American astronauts to the Moon, has come to represent the pinnacle of postwar American optimism and support for large-scale, technically complex national undertakings. Success in 1969 lent credence to Webb's faith in "space age management." By the 1980s such "technocratic optimism" had precipitously declined. Since 1985, with the publication of Walter A. McDougall's Pulitzer Prize winning. . . The Heavens and the Earth, the rise and decline of such optimism has often been framed in the context of Cold War ideology and competition...

We investigated the incidence of hip fracture in patients aged ≥50 years in 2015 in Niigata Prefecture, Japan. We also determined the long-term trend in hip fracture incidence from 1985 to 2015. In 2015, 3214 hip fractures occurred in Niigata Prefecture. The crude incidence rate of hip fracture was 282.7 per 100,000 persons per year (122.9 in men and 416.4 in women). The incidence of hip fracture decreased from 2010 to 2015 in all age groups except in men aged 65-69 years and women aged 60-64 years. The percentage of patients who took anti-osteoporotic medication before their hip fractures increased from 10...

Roger Gosden
Jean Purdy is almost forgotten as one of the British trio that introduced clinical IVF to the world. An unlikely pioneer, she qualified as a nurse but through indefatigable effort and unstinting loyalty to a programme that faced vitriolic opposition she became the clinical embryologist for the first IVF baby. In 1980, she helped to launch fertility services as the 'Technical Director' of Bourn Hall Clinic, near Cambridge. Although Robert Edwards and Patrick Steptoe generously credited her role in research and clinical care, a premature death in 1985 at age 39 robbed her of the reward of witnessing the blossoming of assisted reproductive technologies for patients around the world...

We quantified trends in the 1985 to 2015 summer bottom-water temperature on the northern Gulf of Mexico (nGOM) continental shelf for data collected at 88 stations with depths ranging from 3 to 63 m. The analysis was supplemented with monthly data collected from 1963 to 1965 in the same area. The seasonal summer peak in average bottom-water temperature varied concurrently with air temperature, but with a 2- to 5-month lag. The summer bottom-water temperature declined gradually with depth from 30 oC at stations closest to the shore, to 20 oC at the offshore edge of the study area, and increased an average 0...
