Enzyme replacement following total pancreatectomy; population analysis

Perspectives in Surgery, 2022
Introduction: Total pancreatectomy (TPE) inevitably leads to absolute exocrine pancreatic insufficiency (EPI). No specific recommendations are available for enzyme replacement in such cases. The aim of our analysis was to explore the actual EPI replacement rates among patients following TPE after a certain period of time from the surgery. Methods: This

Reversing Wolbachia-based population replacement

Trends in Parasitology, 2003
Genetic manipulation that reduces the competence of a vector population to transmit pathogens would provide a useful tool to complement current control strategies, which are based primarily on the reduction/exclusion of vector populations and the prophylactic/therapeutic treatment of the vertebrate host population.

Integrating pyriproxyfen into the incompatible insect technique enhances mosquito population suppression efficiency and eliminates the risk of population replacement.

Pest Management Science
BACKGROUND The incompatible insect technique (IIT) has been used for Aedes mosquito population suppression to curb the transmission of dengue. However, its wide application is limited owing to the low output of male mosquitoes and the risk of population ...

Markov population replacement processes

Advances in Applied Probability, 1995
We consider a migration process whose singleton process is a time-dependent Markov replacement process. For the singleton process, which may be treated as either open or closed, we study the limiting distribution, the distribution of the time to replacement and related quantities. For a replacement process in equilibrium we obtain a version of Little's

Population replacement and persistence

1999
Abstract Persistence of a population involves both replacement of people, a biodemographic process, and of domestic units, a socio-demographic process. In the preceding chapter we considered Turkana fertility in some detail, with an emphasis on the biological side.

Transdermal oestrogen replacement therapy in a Finnish population

Maturitas, 1991
In an open, multicentre study, transdermal administration of oestradiol (E2) by means of skin patches was investigated in a Finnish patient population suffering from typical post-menopausal symptoms. A total of 249 women applied a patch twice weekly for 6 months.

Population Ageing, Population Decline and Replacement Migration in Europe

2012
This chapter looks predominantly at the possible role migration might play in containing ageing of European populations. We present selected results of simulations of migration flows from outside the system of 27 countries which would be hypothetically needed to maintain the sizes and structures of the populations under study.

Sampling without replacement from finite populations

Trabajos de Estadistica, 1957
La teoria desarrollada en relacion con el muestreo se considero primeramente en relacion con poblaciones infinitas, e igual probabilidad de seleccion para la extraccion de cualquier unidad de muestreo. En las aplicaciones, sin embargo, se ha encontrado mas satisfactorio considerar la poblacion como finita, sin reemplazamiento al seleccionar las ...

Mortality in the Veneto population on renal replacement therapy

Journal of Nephrology, 2013
This section reports survival rates for patients on renal replacement therapy (RRT). The data obtained from the Veneto Dialysis and Transplantation Registry (VDTR) cover the whole population in the region. Patients on RRT alive on 31 December of each year were assumed to be at risk of dying in the following year. Furthermore, time-to-event analysis was
