This study examines the locations of family homes, medical schools and places of specialist training, and work of doctors qualifying from UK medical schools in 5 calendar years between 1974 and 1993. The contribution of each UK region to the medical workforce relative to its population is assessed and trends over time are examined. The relationship between place of family home and medical school attended is examined for 14,108 doctors. Career appointment location and its relationship to medical school and family home loc‐ation are examined for over 4000 doctors. For the qualifiers of 1983, an additional analysis incorporating place of training is included. Large differences were found in the percentage of medical students from local family homes attending each regional medical school. In some cases differences reflected local populations but other cases had no obvious cause. Over all cohorts studied, 38% of respondents attended a medical school in the region of their family home (32% of 1993 qualifiers), 42% held a career post in the same region as their medical school, and 38% held a career post in the same region as their family home. Among the qualifiers of 1983, 65% had a career post in the same region as their postgraduate training, 34% also attended medical school in the same region, and 19% also came from family homes in the same region. More women than men took up a career post in the same region as their postgraduate training. The relationships to family home and medical school did not differ by gender. Consultants appeared slightly less likely than GPs to have stayed within a region, but this difference was not statistically significant. 相似文献

An equation for the mean residence time (MRT) of drug in the body is derived for the system where drug is injected intravenously into a one-compartment model and eliminated by a single, capacity-limited process. This MRT is a complex function of dose, volume, V
m, and K
m but degenerates into the classical volume/clearance expression under limiting low-dose conditions (K
m C
0). The equation was validated by comparison of the MRT obtained by direct calculation versus numerical area estimation for simulated data. The equation may be useful analytically in the estimation of the fundamental Michaelis–Menten parameters, V
m and K
m, from experimental data. 相似文献

Summary The bounds of the accumulation profile can be predicted on the basis of the mean disposition residence time (MDRT) of a drug. The time to reach 90% of the plateau level (t
0.9) is less than 3.7 MDRT. This prediction can be improved if, in addition, the variance of disposition residence time (VDRT, CV
D
2
=VDRT/MDRT2), or the terminal exponential coefficient (), is known. For CV
D
2
1 or MDRT1, the time to reach steady state (t0.9) approaches 2.3 MDRT (limiting case of monoexponential drug disposition curve). Conditions are stated under which can be regarded as the principal determinant of the accumulation rate. 相似文献

The processing of food products is an important economic activity of rural households in the Andean Highlands of Perú. Potatoes are processed into several dehydrated products the most common of which are chuño and papa seca. Chuño is a freezedried product made principally from bitter types of potatoes (Solarium juzepczukii and S. curtilobum) while papa seca is made from common varieties. This article describes how these and other products are made and their role within the Peruvian diet. 相似文献

Introduction
rVIII-SingleChain (CSL627), a novel recombinant coagulation factor VIII (FVIII), is under investigation in a phase I/III clinical programme (AFFINITY) for the treatment of haemophilia A. Non-clinical studies were conducted to investigate the pharmacokinetic/pharmacodynamic profile of rVIII-SingleChain in comparison with full-length recombinant FVIII.Materials and Methods
Binding affinity of rVIII-SingleChain for von Willebrand factor was investigated by surface plasmon resonance analysis. The pharmacokinetic profile of rVIII-SingleChain was compared with a marketed full-length recombinant FVIII concentrate (Advate®) in haemophilia A mice, von Willebrand factor knock-out mice, Crl:CD (SD) rats, rabbits and cynomolgus monkeys. Systemic FVIII activity or antigen levels were recorded. Procoagulant activity was measured in an FeCl3-induced arterial occlusion model and by recording thrombin generation activity (ex vivo) after administration of 200–250 IU/kg rVIII-SingleChain or full-length FVIII to haemophilia A mice.Results
rVIII-SingleChain displayed a high affinity for von Willebrand factor (KD = 44 pM vs. 139 pM for full-length recombinant FVIII). In all animal species tested, rVIII-SingleChain had more favourable pharmacokinetic properties than full-length recombinant FVIII: clearance was decreased and area under the curve and terminal half-life were enhanced vs. full-length recombinant FVIII, while in vivo recovery and volume of distribution were equivalent. rVIII-SingleChain showed a prolonged thrombin generation potential and prolonged procoagulant activity vs. full-length recombinant FVIII in an FeCl3-induced arterial occlusion model.Conclusions
rVIII-SingleChain had a higher affinity for von Willebrand factor than full-length recombinant FVIII and displayed favourable pharmacokinetic/pharmacodynamic properties in non-clinical models. 相似文献8.

Aim: Hospitalization of elderly people is often followed by high mortality rates. The aim of this study was to analyze the influence of prior residence on 1‐year mortality after hospital discharge in patients aged 70 years and over. Methods: This was a prospective observational cohort study. Participants were 426 patients discharged from the Internal Medicine Department at a Spanish Hospital who were followed for a 12‐month period. Data collection was carried out during hospitalization and included sociodemographic characteristics, comorbidity (Charlson index), functional (Barthel index and Lawton scale) and cognitive conditions (Short Portable Mental Status Questionnaire), together with parameters related to the disease causing admission (diagnosis related group, laboratory tests, length of hospital stay). Mortality was carried out using telephone interviews. Results: A total of 420 (98.6%) patients were located at the end of follow up. Of these, 95 patients had died, giving an overall 1‐year mortality of 22.6%. The mortality rate for patients living in their private homes was 15.6% versus 24.7% for those living with relatives and 60% for those living in institutions. After adjustment for potential confounders, prior residence was associated with mortality with a hazard ratio of 3.98 (95% CI 1.94–8.17) for those institutionalized and a hazard ration of 1.68 (95% CI 0.99–2.16) for those living with relatives, as compared with patients living in their private homes. Conclusions: Prior residence is associated with 1‐year‐mortality following discharge after controlling for several multidimensional factors. Geriatr Gerontol Int 2012; ??: ??–??. 相似文献

Purpose
Increasing global migration, high obesity in developed countries, and ethnic health inequalities are compelling reasons to monitor immigrant obesity trends. Longitudinal studies of ethnicity, length of residence, and adiposity in contexts outside of the United States are lacking.Methods
Nine waves (2006–2014) of the Household Income and Labour Dynamics in Australia survey were analyzed (n = 20,934; 52% women; 101,717 person-year observations) using random effects modeling to assess average annual change in body mass index (BMI) by ethnic group. A second analysis used an immigrant only cohort (n = 4583; 52% women; 22,301 person-year observations) to examine BMI change by length of residence.Results
Over 9 years, mean BMI increased significantly in all ethnic and Australian-born groups, and by the final wave, mean BMI exceeded 25 kg m?2 for all groups. Trajectories of change did not vary between groups, with the exception of slower BMI increases for North-West European men compared with Australian born. Immigrants residing in Australia for 10–19 years had significantly faster annual increases in BMI compared with long-term immigrants (≥30 years).Conclusions
Immigrants to Australia, regardless of ethnicity, are at risk of obesity over time. Obesity prevention policy should prioritize immigrants in the early-mid settlement period. 相似文献10.
