- Changes in lung cancer incidence and mortality in Estonia were studied for 20 years (1968-87). A steady upward trend was observed for men and women. The 1983-87/1968-72 age-standardized incidence rate ratio was 1.22 (95% confidence interval (CI) 1.15-1.29) in men and 1.34 (95% CI 1.16-1.54) in women. The corresponding mortality rate ratio was 1.26 (95% CI 1.18-1.34) in men and 1.35 (95% CI 1.16-1.57) in women. The age-specific incidence and mortality rates increased clearly towards the younger birth cohorts. For men and women, the increase was most evident for the age group 45-64 years. In women there was a more rapid increase in incidence and mortality than in men. It may be a result of a substantial increase of tobacco smoking, particularly among women, after the World War II. The high and still rising occurrence of lung cancer is closely related to the high prevalence of smoking; in addition, high tar yields in domestic cigarettes could have been responsible for an elevated lung cancer risk during the past decades. There is not tobacco control programme in Estonia, and existing legislation and regulations do not defend the non-smoking population.

Tidskriftsartikel (refereegranskat)abstract
- Growth monitoring is so far not implemented on a large scale in the Somali health services. Available reports indicate that growth faltering is common. However, the use of growth charts as a tool for health education has been questioned. This study examines the ability of 199, predominantly illiterate, rural Somali mothers to understand the growth chart message after an intensive period of growth chart use and education. During a home-based interview the mothers were asked to combine a set of four growth curves with a set of four pictures, showing the corresponding developments of four children. The mothers managed significantly better to interpret the charts than could be expected by chance alone. Maternal age, number of children and literacy did not differ much between those who correctly and incorrectly combined pictures and charts. Almost all mothers recognised the value of the growth chart as being good for the control and promotion of their children's health and/or growth. We conclude that the growth chart may be an applicable and appropriate tool even with illiterate mothers, provided that other prerequisites for successful growth monitoring, e.g. appropriate health services, are available.

Intestinal colonization with Enterobacteriaceae in Pakistani and Swedish hospital-delivered infants.
- 1991

Ingår i: Acta paediatrica Scandinavica. - 0001-656X. ; 80:6-7, s. 602-10

Tidskriftsartikel (refereegranskat)abstract
- Rectal cultures from Swedish and Pakistani hospital-delivered newborn infants were analysed regarding the early acquisition of enterobacteria. Swedish infants were delivered vaginally, Pakistani infants were delivered either vaginally or by caesarean section. The Swedish infants were all breast-fed, whereas breastfeeding was incomplete and often started late among the Pakistani infants. Both groups of Pakistani infants were more rapidly colonized with enterobacteria than were the Swedish infants. Cultures from Swedish infants seldom yielded more than one kind of enterobacteria; E. coli and Klebsiella were most frequently isolated. E. coli dominated in both Pakistani groups, but especially caesarean section delivered infants were in addition often colonized with Proteus, Klebsiella, Enterobacter or Citrobacter species. Breastfeeding from the first day of life reduced colonization with Klebsiella/Enterobacter/Citrobacter. The results suggest that environmental exposure, delivery mode and early feeding habits all influence the early intestinal colonization with enterobacteria.

Improvement of peripheral nerve function after institution of insulin treatment in diabetes mellitus. A case-control study
- 1983
-
Ingår i: Acta Medica Scandinavica. - 0001-6101. ; 213:4, s. 283-287
-
Tidskriftsartikel (refereegranskat)abstract
- The influence of improved diabetic control on peripheral nerve function was studied before and 3-4 months after institution of insulin treatment in 22 diabetics unsatisfactorily controlled by oral hypoglycemic agents. After institution of insulin treatment, diabetic control was improved as demonstrated by decreasing levels of HbA1. There was an overall tendency towards improvement of motor and sensory conduction velocities, however significant only in the upper extremities. There was a tendency towards improved temperature sensitivity in the legs, while no changes occurred in the hands and face. The sensation for vibration did not change. It is concluded that improved diabetic control, even in elderly patients with long-standing diabetes, is followed by neurophysiological signs of improved peripheral nerve function.

Tobacco smoke exposure and pregnancy outcome among working women. A prospective study at prenatal care centers in Orebro County, Sweden
- 1991

Ingår i: Am J Epidemiol. - 0002-9262. ; 133:4, s. 338-47

Tidskriftsartikel (refereegranskat)abstract
- Among 4,687 women undergoing prenatal care in Orebro County, Sweden, from October 1980 to June 1983, 678 nonsmokers reported passive exposure to tobacco smoke. Of these women, 267 had been passively exposed at work, and the risk ratio (RR) for intrauterine death (spontaneous abortion or stillbirth) among these pregnancies was increased to 1.53 (95% confidence interval (CI) 0.98-2.38) compared with pregnancies of unexposed working women. This could not be explained by age, previous spontaneous abortion, educational level, planning of pregnancy, or alcohol use. The effect was confined to first-trimester fetal loss (adjusted RR = 2.16, 95% CI 1.23-3.81), while active smoking was associated with intrauterine death after the first trimester. Passive exposure in the workplace was weakly associated with preterm birth (less than 37 weeks) but not with low birth weight (less than 2,500 g) among full-term livebirths. Active smoking clearly increased the risk of both of these outcomes. However, passive exposure in the home only did not seem to affect pregnancy outcome. The lack of quantitative exposure data points to the need for more research before passive exposure to tobacco smoke can be regarded as an established hazard to fetal development and survival.

Epidemiology of sickness absence in a Swedish county in 1985, 1986 and 1987 : A three year longitudinal study with focus on gender, age and occupation
- 1994
-
Ingår i: Scandinavian Journal of Social Medicine. - : Sage Publications. - 0300-8037. ; 22:1, s. 27-34
-
Tidskriftsartikel (refereegranskat)abstract
- In order to get a better epidemiological base for preventive intervention in the county of Östergötland, Sweden, a comprehensive study of sickness absence was done. During the years 1985, 1986 and 1987, all new periods of sick-leave exceeding seven days were registered with demographic variables. This information was related to data about the total population of Östergötland. Each year approx. 45,000 persons had approx. 61,000 sickness spells. These figures were stable over the years while the number of sick-leave days increased. Blue-collar occupations had the highest sick-leave rates and the female sick-leave rate was higher in general and much higher in most male-dominated occupations. The male rate was lower within female-dominated areas, except among secretaries and textile workers. Females in extremely male-dominated groups had the highest rates, while both male and female sick-leave rates were lower in more gender-integrated occupations.

Enteric adenovirus type 41 : genome organization and specific detection procedures
- 1992
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Enteric adenoviruses (EAd) types 40 and 41 (Ad40 and Ad41) representing subgenus F, are primary pathogens of children being second only to rotaviruses as the most important cause of infantile diarrhea.The EAds differ from all other adenoviruses in their inability to grow in most conventional established cell lines and have been suggested to be deficient in some early gene functions since they could be complemented by Ad 5 early regions EIA and E1B. In order to search for differences that could explain its characteristic growth restriction, the early regions EIA and E1B of Ad41 (strain D389) were sequenced, analysed and compared with the corresponding regions of Adl2, Ad7, Ad2, and Ad4. As revealed by the analysis of Ad2, three major mRNAs of 9S, 12S and 13S are generated from region EIA. The EIA region of Ad41 encodes two mRNAs corresponding to the 12S and 13S mRNAs. Only the 13S mRNA is transcribed at detectable levels. This mRNA can be translated into a 251 aa putative protein that contains the three highly conserved domains found in all other human adenoviruses and shown to be responsible for many important regulatory functions during infection.The E1B region of Ad41 encodes three transcripts that correspond to 22S, 14S and 9S mRNA of Ad2. No equivalent to the 13S mRNA of Ad2 E1B is found. In addition the Ad41 14S mRNA exhibits an additional exon of 23 bp created by a donor and an acceptor splice sites not desribed for other adenovirus E1B sequences.Due to their growth restriction in conventional cultures, rapid diagnostic procedures developed for the enteric adenovirus infections have mainly been aimed at the detection of viral antigens or nucleic acids. This thesis also describes several procedures developed for the general detection of adenoviruses and specific detection of the enteric types in stools specimens. General and specific hybridization assays were developed by use of two BamHI clones obtained from the EIA region of Ad41. One- and two-step PCR procedures were also developed for the general detection of adenoviruses using primers corresponding to highly conserved sequences within the hexon gene. Subgenus F specific one- and two-step PCRs were developed by using primers located in the Ad41 E1B region.The one-step PCR systems were tested and validated against isolation in tissue culture, DNA restriction enzyme analysis and a commercial latex agglutination test in the study of 60 specimens obtained from children with rotavirus negative diarrhea. The asymptomatic fecal excretion of adenoviruses was evaluated by two-step PCR amplifications on samples from 50 healthy children, 50 healthy adults, and 50 adults suffering from diarrhea.Finally, a simplified procedure for detection, discrimination and typing of EAd was also designed by combining the one-step PCR amplification of the hexon region with the restriction of the 300 bp product.
