BACKGROUND This study compares registry and non-registry approaches to linking 2006 Census of Population data for Manitoba and Ontario to hospital data from the Discharge Abstract Database (DAD). DATA AND METHODS Using a probabilistic linkage, the registry approach linked the census data to provincial health insurance registries, followed by a deterministic linkage to the DAD based on health ...

Guanylhydrazones are molecules with great pharmacological potential in various therapeutic areas, including antitumoral activity. Factorial design is an excellent tool in the optimization of a chromatographic method, because it is possible quickly change factors such as temperature, mobile phase composition, mobile phase pH, column length, among others to establish the optimal conditions of ana...

The key problem of the theory of exterior differential systems (EDS) is to decide whether or not a system is in involution. The special case of EDSs generated by one-forms (Pfaffian systems) can be adequately illustrated by a 2-dimensional example. In 4 dimensions two such problems arise in a natural way, namely, the Riemann-Lanczos and the Weyl-Lanczos problems. It is known from the work of Ba...

The abbreviations section includes a strange mixture of terms that are in everyday use and often bizarre entries (for instance, CRTAP [cartilage associated protein] and DAD [doctor assisted suicide]), which admittedly may represent commonly used terms in the authors’ local areas. There are duplications and ‘Americanisms’ (for instance, CBC [complete blood count] and FBC [full blood count]), whi...

It is increasingly recognized that good reliability practice requires giving attention to the specification of joint distributions for failure times. If the marginal distributions are known then the problem of selecting a marginal distribution is equivalent to that of selecting a copula. In the competing risk situation, identification of the copula alone is important, for together with competin...

Materials and methods: The study was based on a mixed method, based partly on real-world data on 546 RRMS patients treated with IFNβ from a previous observational study [1], and partly from the review of cost studies in the published literature. Reverting and fluctuating patients were not considered in this evaluation. EDSS level (measured at 630 months) and average relapse rates were analysed ...

BACKGROUND Health workforce distribution is so important in access posture, coverage and equity. Following millennium development goals (MDGs), special attention to health workforces in relation with maternal and child health is required. OBJECTIVE The aim of the current study was to determine distribution of maternal and child health related workforces in Iran during 2010-2012, using inequal...

During the preliminary stages of many engineering design tasks, the underlying search space is unbounded and inexact. Initial decisions are made when information is incomplete and many goals are contradictory. This sort of problem appeared in Catalonia for the identification of appropriate wastewater treatment systems in small communities, as well as for proposing appropriate operational and ma...

Determining Depth-Area-Duration (DAD) curves in drainage basins is one of the applied researches in hydrology. DAD curves exhibit the depth and the area covered by the rainfall with a particular duration. DAD analysis is widely used in characterization of precipitation extremes for specification of so-called design storms. In this study the DAD curves for the Kurdistan province were prepared an...

One hundred fourteen patients (66 men and 48 women; mean age, 49 years) underwent spine stabilization using a dynamic neutralization system between January 1999 and August 2010 for degenerative disk disease, spinal instability, or spinal stenosis. Mean follow-up was 6.8 years (range, 1-11 years). Seven patients were lost to follow-up. Radiological examination and clinical evaluation, including ...
