Randomized controlled trials in urologic oncology: a demographic analysis.

We examined randomized controlled trials in urologic oncology published in 1992. Particular emphasis was placed on the contribution of urologists and studies with a surgical arm. Randomized controlled trials in bladder, prostate, testis and renal carcinoma were identified by a structured MEDLINE search. Results were analyzed to determine modality of treatment, disease site, principal author, country of origin, cohort size, number of participating centers, source of funding and type of journal. MEDLINE retrieved 162 references of which 126 were excluded by title (10), abstracts (105) or articles (11) as not urologic oncology (7) or not a randomized controlled trials (119). Of the qualifying 36 randomized controlled trials, the site of the disease was bladder (44%), prostate (39%) renal (14%) and testis (3%). All except six randomized controlled trials compared medical therapies. Only five had a surgical arm and one had a radiation arm. Cohort size was > 100 in 67% of randomized controlled trials with most (56%) being multicenter trials. Participating countries were Europe, excluding the UK (35%), the US (23%), Japan (20%), Canada (13%), and the UK (10%). Urologists were the principal authors of 67% of the papers describing randomized controlled trials. The majority of trials were published in nonsurgical journals (50%). Funding for randomized controlled trials was from government (28%), pharmaceutical companies (19%), private sources (3%) and not stated (50%). Although randomized controlled trials are being conducted in urologic oncology, there are relatively few compared with trials using inferior study designs. A still smaller proportion of randomized controlled trials contain a surgical arm.

[Genetic demographic analysis of western Ukrainian populations: the marriage structure of populations from the Khmel'nitskii oblast with respect to ethnicity and birthplace].

Ukrainians account for 85 and 91% of the populations of the city of Khmel'nitskii and the town of Starokonstantinov (Khmel'nitskii oblast, western Ukraine), respectively, and for 97% of the rural population of the Khmel'nitskii oblast. The proportions of Russians in the urban and rural populations of the Khmel'nitskii oblast are 7-10 and 1%, respectively. Between 1960 and 1995-1998, the proportions of Ukrainians in all populations studied increased and the proportion of interethnic marriages steadily decreased. The marriage association coefficient (K) with respect to ethnicity varied from 0.35 to 0.76 in different years. The highest assortative marriage indices (A') with respect to ethnicity were 75-98 and 71-84% in Ukrainians and Jews, respectively. The migration coefficient was 0.58-0.77. Western Ukrainian populations differ from eastern Ukrainian ones in a steadily decreasing outbreeding component.

[Occupational-demographic analysis of employment of the population of USSR, RSFSR and Ukrainian SSR according to the general census].

Aging of the manpower resources is still continuing in this country as a whole and in individual republics, the average age approaching 40 years thus stepping on the verge of the older age group. The aging people are being 'pushed away' from most professions and occupations. Judging from the results of the recent general census of the population, in the USSR the portion of the 'pushed away' manpower has amounted to 80.7%. The growing discrepancy between the aging manpower resources and the modern industry demands are expressed in terms of increased morbidity and mortality among the productive age-groups.

[Skeletochronological determination of age and demographic analysis of a population of Acanthodactylus pardalis (Lischenstein, 1823) of the Kerkennah islands (Tunisia)].

The skeletochronological analysis of 34 adult lizards from population of Acanthodactylus pardalis of Kerkennah islands in Tunisia enabled to: determine the individual age of the animals; delineate four various cohorts making up the studied population; evaluate around 4 years life span in nature of this species; point out that the renewal rate accounts for 41% of its population. Moreover the method of "maximums successifs" is applied on sizeable sample in order to shore up the obtained results.

Demographic analysis of childhood pedestrian injuries.

Factors in a child's living environment and socioeconomic background that contribute to the risk of pedestrian injury were studied. In 1982, in the city of Memphis, there were 210 pedestrian injuries among children aged 0 to 14 years, a rate of 138/100,000 children. The injured child was most often male, with mean age of 7.3 years; the child was usually struck while crossing the street between intersections, most commonly during the hours from 2 to 7 PM. Pedestrian injuries occurred in 81 of the 142 census tracts in the city. Compared with census tracts without reported injuries, these tracts had twice the percentage of nonwhite population, lower household incomes, more children living in female-headed households, more families living below the poverty level, and greater household crowding (all differences significant at P less than .01). The single variable of crowded housing per acre best predicted the number of injuries per acre in multiple regression analysis. A group of children who are at high risk of pedestrian injury through increased exposure in the environment was identified. As with many other types of injuries, modification of external factors--in this case, traffic engineering modifications--seems to be the most practical solution.
