BACKGROUND There are many opinions and controversies regard the effect of lateral wedge insoles and valgus stress 3point knee braces in treatment of medial compartment knee osteoarthritis (OA). In this study we compared the effect of lateral wedge insoles and 3 point knee supports in treatment of medial compartment knee OA. METHOD Sixty patients (35-65 years), with knee pain and genu varum an...

In order to assess the role of right ventricular and left ventricular dysfunction in patients with cardiogenic shock associated with combined right ventricular and inferior myocardial infarction, we reviewed the clinical records and haemodynamic data of 18 patients with inferior myocardial infarction and cardiogenic shock. Six of these patients had haemodynamic evidence of right ventricular dys...

BACKGROUND Stepped wedge randomised trial designs involve sequential roll-out of an intervention to participants (individuals or clusters) over a number of time periods. By the end of the study, all participants will have received the intervention, although the order in which participants receive the intervention is determined at random. The design is particularly relevant where it is predicted...

Abstract 3D symmetric tensor fields have a wide range of applications in medicine, science, and engineering. The topology can provide key insight into their structures. In this paper we study the number possible topological bifurcations linear fields. Using linearity/planarity classification wedge/trisector classification, explore four types that change connectivity degenerate curves as well lo...

introduction wedge modifiers are commonly applied in external beam radiotherapy to change the dose distribution corresponding to the body contour and to obtain a uniform dose distribution within the target volume. since the radiation dose delivered to the target must be within ±5% of the prescribed dose, accurate dose calculation by a treatment planning system (tps) is important. the objective ...

BACKGROUND Stepped wedge cluster randomised trials frequently involve a relatively small number of clusters. The most common frameworks used to analyse data from these types of trials are generalised estimating equations and generalised linear mixed models. A topic of much research into these methods has been their application to cluster randomised trial data and, in particular, the number of c...

In this paper, we give some sufficient conditions for the infinite collisions of independent simple random walks on a wedge comb with profile {f(n), n ∈ Z}. One interesting result is that two independent simple random walks on the wedge comb will collide infinitely many times if f(n) has a growth order as n log n. On the other hand, if {f(n);n ∈ Z} are given by i.i.d. non-negative random variab...
