- We investigated prospectively the risk of lung cancer in relation to socioeconomic status (SES) in 22387 middle-aged individuals who attended a screening program in the city of Malmo, Sweden between 1974 and 1992. We also examined the relationship between SES and histologic subtype in smokers. By 2003, a total of 550 lung cancer cases had been identified. Relative risks (RR) were calculated with adjustment for age, current smoking, inhalation habits and marital status at baseline in the low SES group compared to high SES group. Among smokers, the RR (95% confidence interval (Cl)) for lung cancer in the tow SES group of men was 1.39 (1.11-1.73), and women 1.56 (1.04-2.34). Also among smokers, low SES was associated with an increased risk of squamous cell carcinoma in men; RR 1.89 (1.16-2.81) and women; RR 7.10 (1.63-30.86), and with an increased risk of mesothelioma in men RR 9.97 (1.29-76.96). We conclude that Low SES groups run an increased risk of lung cancer despite accounting for smoking habits. Furthermore, tow SES was positively associated with squamous cell carcinoma and mesothelioma. Our results suggest that the association between low SES and lung cancer could be mediated by unaccounted for smoking exposure, Lifestyle or occupational hazards. (C) 2005 Elsevier Ireland Ltd.

- BACKGROUND AND DESIGN: The hypothesis that diets rich in total and saturated fat and poor in unsaturated fats increase the risk for cardiovascular disease is still vividly debated. The aim of this study was to examine whether total fat, saturated fat, or unsaturated fat intakes are independent risk factors for cardiovascular events in a large population-based cohort. METHODS: 28 098 middle-aged individuals (61% women) participated in the Malmo Diet and Cancer Study between 1991 and 1996. In this analysis, individuals with an earlier history of cardiovascular disease were excluded. With adjustments made for confounding by age and various anthropometric, social, dietary, and life-style factors, hazard ratios (HR) were estimated for individuals categorized by quartiles of fat intake [HR (95% confidence interval, CI), Cox's regression model]. RESULTS: No trend towards higher cardiovascular event risk for women or men with higher total or saturated fat intakes, was observed. Total fat: HR (95% CI) for fourth quartile was 0.98 (0.77-1.25) for women, 1.02 (0.84-1.23) for men; saturated fat: 0.98 (0.71-1.33) for women and 1.05 (0.83-1.34) for men. Inverse associations between unsaturated fat intake and cardiovascular event risk were not observed. CONCLUSIONS: In relation to risks of cardiovascular events, our results do not suggest any benefit from a limited total or saturated fat intake, nor from relatively high intake of unsaturated fat.

- We present two monolithic microwave integrated circuit (MMIC) cryogenic broadband low-noise amplifiers (LNAs) based on the 100 nm gate length InP high-electron mobility transistor technology for the frequency range of 0.3-14 and 16-28 GHz. The 0.3-14 GHz three-stage LNA exhibited a gain of 41.6 ± 1.4 dB and an average noise temperature of 3.5 K with a minimum noise temperature of 2.2 K at 6 GHz when cooled down to 4 K. The 16-28 GHz three-stage LNA showed a gain of 32.3 ± 1.8 dB and an average noise temperature of 6.3 K with a minimum noise temperature of 4.8 K at 20.8 GHz at the ambient temperature of 4 K. This is the first demonstration of cryogenic MMIC LNA covering the whole K-band. To the best of the authors' knowledge, the cryogenic MMIC LNAs demonstrated the state-of-the-art noise performance in the 0.3-14 and 16-28 GHz frequency range.

- BACKGROUND: Alcohol as a cause of death in middle-aged patients is well-known from clinical studies. A similarly important correlation in the general population of urban middle-aged men is highly underestimated. Health screening investigations have shown that mortality related to alcohol is five times more common in nonparticipants than in participants. From the mid-70s, the Malmoe Screening and Intervention Study (MSIS) commenced screening investigations including a large number of residents of Malmoe. One goal was to find intervention programs for individuals in an early development of problem drinking, thereby preventing development of serious complications of endstage alcoholism. Herein, we report on the mortality of heavy drinkers (drinking more than 40 g alcohol/day) who were randomized to an intervention or control procedure and whose median survival was 13 years postentry into the MSIS. METHODS: Health-screened men, aged 45-49 years at the initial screening examination and displaying serum gamma-glutamyltransferase (GT) in the top decentile of the GT distribution, were included. A total of 978 out of 11,257 participants met this criteria. A randomized intervention and control study was performed for four years and consisted of men (n = 667) who were born between 1927-1937 and who had two consecutive high GT values within 3 weeks along with heavy alcohol consumption. Half the individuals were informed of the test results and invited for further assessment by a senior physician (n = 365). The principles for brief intervention (DiClemente et al.,1991; Miller and Sanchez, 1993; National Institute of Alcohol Abuse and Alcoholism, 1999) were applied. The other half of the men (n = 302) were left with the information that they had a high GT value and were followed up with laboratory checkups every 2nd year. Mortality was followed up until 1991 and information on deaths was obtained from hospital and police records, necropsy reports, and death certificates. RESULTS: Long-term follow-up of mortality for 10-16 years (median, 13 years) showed that 124 of the 978 men had died (12.7%). Autopsy was performed in 96.5% of the cases. In 59 men (48%), death was alcohol-related. In the intervention group (n = 365), 38 (10.4%) men were dead and in the control group (n = 302), 42 (13.9%) men had died. There was a statistically significant difference (p = 0.026), with advantage for treatment. Less alcohol-related deaths and deaths occurring later during follow-up were found in the intervention group compared with the control group. The difference between the groups in total mortality, coronary heart disease, and cancer death was not statistically significant. CONCLUSIONS: These findings support previous results from the MSIS study indicating that long-term intervention in urban males with alcohol-induced GT increases may be beneficial in terms of survival.

- Purpose We examined whether prostate-specific antigen (PSA) forms and human kallikrein 2 (hK2) measured at age 44 to 50 years predict long-term risk of incident prostate cancer. Methods From 1974 to 1986, 21,277 men age <= 50 years in Malmo, Sweden, enrolled onto a cardiovascular study (74% participation). The rate of PSA screening in this population is low. According to the Swedish Cancer Registry, 498 were later diagnosed with prostate cancer. We measured hK2, free PSA, and total PSA (tPSA) in archived blood plasma from 462 participants later diagnosed with prostate cancer and from 1,222 matched controls. Conditional logistic regression was used to test for association of prostate cancer with hK2 and PSA forms measured at baseline. Results Median delay between venipuncture and prostate cancer diagnosis was 18 years. hK2 and all PSA forms were strongly associated with prostate cancer (all P < .0005). None of the 90 anthropometric, lifestyle, biochemical, and medical history variables measured at baseline was importantly predictive. A tPSA increase of 1 ng/mL was associated with an increase in odds of cancer of 3.69 (95% CI, 2.99 to 4.56); addition of other PSA forms or hK2 did not add to the predictive value of tPSA. tPSA remained predictive for men diagnosed >= 20 years after venipuncture, and the predictive value remained unchanged in an analysis restricted to palpable disease. Conclusion A single PSA test at age 44 to 50 years predicts subsequent clinically diagnosed prostate cancer. This raises the possibility of risk stratification for prostate cancer screening programs.

- It was recently reported that the synthetic compound estren increases bone mass without affecting reproductive organs or classic transcription. The aim of the present study was to further characterize the in vivo and in vitro effects of estren. We demonstrate that estren is a selective estrogen receptor modulator (SERM) with a strong effect on thymus, a moderate effect on uterus and trabecular bone, but no major effect on fat or cortical bone in 11-month-old ovariectomized mice. The effect of estren on trabecular bone and uterus is mediated via estrogen receptors (ERs) because no effect is seen in ER double-inactivated mice. Furthermore, with the use of ERalpha- and ERbeta-expressing reporter cell lines, we demonstrate that estren displays an agonistic effect on transcriptional activity of an estrogen-responsive element-driven reporter gene with a degree of agonism similar to that of 17beta-estradiol for both ERalpha and ERbeta. Thus, estren has the capacity to exert genomic effects via both ERalpha and ERbeta. We conclude, in contrast to what was previously reported by others, that estren is a SERM with transcriptional activity.

Tidskriftsartikel (refereegranskat)abstract
- Environmental factors, including viral infections, may explain an increasing and fluctuating incidence of childhood type 1 diabetes (T1D). Ljungan virus (LV) isolated from bank voles have been implicated, but it is unclear whether LV contributes to islet autoimmunity, progression to clinical onset, or both, of T1D. The aim was to test whether LV antibodies (LVAb) were related to HLA-DQ and islet autoantibodies in newly diagnosed T1D patients (n = 676) and controls (n = 309). Patients, 0-18 years of age, diagnosed with T1D in 1996-2005 were analyzed for LVAb, HLA-DQ genotypes, and all seven known islet autoantibodies (GADA, IA-2A, IAA, ICA, ZnT8RA, ZnT8WA, and ZnT8QA). LVAb at 75th percentile, defined as cut off, was 90 (range 6-3936) U/mL and 4th quartile LVAb were found in 25% (170/676) of which 64% were < 10 (n = 108, p < 0.0001), and 27% were < 5 (n = 45; p < 0.0001) years old. The 4th quartile LVAb in children < 10 years of age correlated to HLA DQ2/8, 8/8, and 8/X (p < 0.0001). Furthermore, in the group with 4th quartile LVAb, 55% were IAA positive (p = 0.01) and correlation was found between 4th quartile LVAb and IAA in children < 10 years of age (p = 0.035). It is concluded that 1) LVAb were common among the young T1D patients and LVAb levels were higher in the younger age groups; 2) 4th quartile LVAb correlated with IAA; and 3) there was a correlation between 4th quartile LVAb and HLA-DQ8, particularly in the young patients. The presence of LVAb supports the notion that prior exposure to LV may be associated with T1D.

- Background: Long-term frozen storage may alter the results of prostate-specific antigen (PSA) measurements, mainly because of degradation of free PSA (fPSA) in vitro. We compared the effects of long-term storage on fPSA, total PSA (tPSA), and complexed PSA (cPSA) in serum vs EDTA-plasma samples. Methods: We measured fPSA and tPSA concentrations in matched pairs of archival serum and EDTA-plasma samples (stored frozen at -20 degrees C for 20 years) from a large population-based cohort in Malmo, Sweden. We also compared concentrations in age-matched men with those in samples not subjected to long-term storage, obtained from participants in a population-based study of prostate cancer screening in Goteborg, Sweden. These contemporary samples were handled according to standardized preanalytical. and analytical protocols aimed at minimizing in vitro degradation. tPSA and fPSA measurements were performed with a commercial assay (Prostatus Dual Assay; Perkin-Elmer Life Sciences). Results: Concentrations of tPSA and fPSA and calculated cPSA (tPSA-fPSA) in archival plasma were not significantly different from those in contemporary serum from age-matched men. In archival serum, however, random variability of fPSA was higher vs plasma than in contemporary samples, whereas systematic error of fPSA analyses was similarly small in archival and contemporary serum and plasma. Conclusions: Concentrations of tPSA and calculated cPSA were highly stable in plasma and serum samples subjected to long-term storage at -20 degrees C. Greater random variability, rather than a systematic decrease, may explain differences in fPSA analyses observed in archival serum. (c) 2006 American Association for Clinical Chemistry.
