Intraoperative periprosthetic femoral fractures (IPFF) have been studied extensively for total hip arthroplasties, but not for hemiarthroplasties. Recent series in the literature show an IPFF rate for hemiarthroplasties ranging from 0% to 14%. The present study was designed to determine the prevalence and outcome after IPFF during non-cemented hemiarthroplasty. In addition, the surgical step at...

A special task force of the American Society of Clinical Oncology (ASCO) recently issued a Guidance Statement on the Cost of Care , which advises oncologists to speak with their patients about the cost of treatment. While urging ASCO to also address underlying economic factors that drive costs, the guidance focused on issues at the practice level. " The task force tried to address the rising co...

BACKGROUND Shared decision making (SDM) is generally treated as good practice in health-care interactions. Conversation analytic research has yielded detailed findings about decision making in health-care encounters. OBJECTIVE To map decision making communication practices relevant to health-care outcomes in face-to-face interactions yielded by prior conversation analyses, and to examine thei...

It was reported by Oreskes, Rosenblatt, Spiera, and Meadow (1968) that patients with depressive symptomatology show a high percentage of elevated rheumatoid factor titre as measured by the sensitized sheep cell test of Heller, Kolodny, Lepow, Jacobson, Rivera, and Marks (1955). They studied the blood samples of patients who were admitted to an acute psychiatric service. We were interested to as...

BACKGROUND AND PURPOSE Despite the fact that there have been some reports on poor performance, titanium femoral stems intended for cemented fixation are still used at some centers in Europe. In this population-based registry study, we examined the results of the most frequently used cemented titanium stem in Norway. PATIENTS AND METHODS 11,876 cases implanted with the cemented Titan stem were...

A new numerical model for the on-demand computation of optimal ship routes based on sea-state forecasts has been developed. The model, named VISIR (discoVerIng Safe and effIcient Routes) is designed to support decisionmakers when planning a marine voyage. The first version of the system, VISIR-I, considers medium and small motor vessels with lengths of up to a few tens of metres and a displacem...

AISI 1045 can be machined well in all machining operations, namely drilling, milling, turning, broaching and grinding. It has many applications, such as crankshafts, rollers, spindles, shafts, gears. Wiper geometry a great influence on cutting forces (Fr, Ff, Fc R), temperature, material removal rate (MRR) surface roughness (Ra). inserts are used to achieve good quality avoid the need buy grind...
