Associations of tissue transglutaminase antibody seropositivity with coronary heart disease: Findings from a prospective cohort study.

Clinical experience and observational studies suggest that individuals with coeliac disease are at increased risk of coronary heart disease (CHD), but the precise mechanism for this is unclear. Laboratory studies suggest that it may relate to tissue transglutaminase antibodies (tTGAs). Our aim was to examine whether seropositivity for tTGA and endomysial antibodies (EMAs) are associated with incident CHD in humans. We used data from Mini-Finland Health Survey, a prospective cohort study of Finnish men and women aged 35-80 at study baseline 1978-80. TTGA and EMA seropositivities were ascertained from baseline blood samples and incident CHD events were identified from national hospitalisation and death registers. Cox regression was used to examine the associations between antibody seropositivity and incident CHD. Of 6887 men and women, 562 were seropositive for tTGAs and 72 for EMAs. During a median follow-up of 26 years, 2367 individuals experienced a CHD event. We found no clear evidence for an association between tTGA positivity (hazard ratio, HR: 1.04, 95% confidence interval, CI: 0.83, 1.30) or EMA positivity (HR: 1.16, 95% CI: 0.77, 1.74) and incident CHD, once pre-existing CVD and known CHD risk factors had been adjusted for. We found no clear evidence for an association of tTGA or EMA seropositivity with incident CHD outcomes, suggesting that tTG autoimmunity is unlikely to be the biological link between coeliac disease and CHD

Does antibacterial treatment for urinary tract infection contribute to the risk of breast cancer?

Low lignan status has been reported to be related to an elevated risk of breast cancer. Since lignan status is reduced by antibacterial medications, it is plausible to hypothesize that repeated use of antibiotics may also be a risk factor for breast cancer. History of treatment for urinary tract infection was studied for its prediction of breast cancer among 9461 Finnish women 19–89 years of age and initially cancer-free. During a follow-up in 1973–1991, a total of 157 breast cancer cases were diagnosed. Women reporting previous or present medication for urinary tract infection at baseline showed an elevated breast cancer risk in comparison with other women. The age-adjusted relative risk was 1.34 (95% confidence interval (CI) = 0.98–1.83). The association was concentrated to women under 50 years of age. The relative risk for these women was 1.74 (95% CI 1.13–2.68), whereas it was 0.97 (95% CI 0.59–1.58) for older women. The relative risk in the younger age-group was 1.47 (95% CI 0.73–2.97) during the first 10 years of follow-up, and 1.93 (95% CI 1.11–3.37) for follow-up times longer than 10 years. These data suggest that premenopausal women using long-term medication for urinary tract infections show a possible elevated risk of future breast cancer. The results are, however, still inconclusive and the hypothesis needs to be tested by other studies. © 2000 Cancer ResearchCampaig

Dietary fat, cholesterol and colorectal cancer in a prospective study

The relationships between consumption of total fat, major dietary fatty acids, cholesterol, consumption of meat and eggs, and the incidence of colorectal cancers were studied in a cohort based on the Finnish Mobile Clinic Health Examination Survey. Baseline (1967–1972) information on habitual food consumption over the preceding year was collected from 9959 men and women free of diagnosed cancer. A total of 109 new colorectal cancer cases were ascertained late 1999. High cholesterol intake was associated with increased risk for colorectal cancers. The relative risk between the highest and lowest quartiles of dietary cholesterol was 3.26 (95% confidence interval 1.54–6.88) after adjusting for age, sex, body mass index, occupation, smoking, geographic region, energy intake and consumption of vegetables, fruits and cereals. Consumption of total fat and intake of saturated, monounsaturated, or polyunsaturated fatty acids were not significantly associated with colorectal cancer risk. Nonsignificant associations were found between consumption of meat and eggs and colorectal cancer risk. The results of the present study indicate that high cholesterol intake may increase colorectal cancer risk, but do not suggest the presence of significant effects of dietary fat intake on colorectal cancer incidence. © 2001 Cancer Research Campaign http://www.bjcancer.co

Comparison of postoperative skeletal stability of maxillary segments after Le Fort I osteotomy, using patient-specific implant versus mini-plate fixation

Background: Three-dimensionally (3D) designed osteotomies and customised osteosynthesis are rapidly becoming standard in maxillofacial reconstructive and deformity surgery. Patient-specific implants (PSIs) have been in use for a few years in orthognathic surgery as well. In Le Fort I osteotomy, wafer-free fixation of the maxillary segment can be performed by individually manufactured cutting and drill guides together with PSIs. Aim: This retrospective study was performed to compare the postoperative skeletal stability of the maxillary segment fixed by patient-specific implants versus mini-plates after Le Fort I osteotomy. Patients: Fifty-one patients were divided into subgroups according to the fixation method and the advancement of the sub-spinal point. The postoperative skeletal stability of the maxillary segment was evaluated from lateral cephalometric radiographs one year postoperatively. Results: No statistically significant differences were found between the postoperative skeletal stability of the PSI and mini-plate fixed maxillae. Prospective studies, possibly with 3D fusion analysis, are warranted to confirm the results. Conclusion: The choice between the two fixation methods does not seem to affect the postoperative skeletal stability of the maxillary segments.

Heavy metal concentrations in males and females of three pine diprionids (Hymenoptera)

Heavy metal concentrations (Cu, Fe, Ni, Cd) in the cocoons of three gregarious pine diprionids, Gilpinia socia, Diprion pini and Neodiprion sertifer, were compared between the species and sexes. The sawflies were reared in the laboratory in colonies from the first instar larvae, being fed on Scots pine (Pinus sylvestis) needles collected from a heavily polluted or a relatively unpolluted site. The levels of copper, iron and nickel were two to three times as high in N. sertifer as in the two other species. Cadmium showed bioaccumulation in all three species. In N. sertifur and G. socia reared on polluted needles, the metal concentrations were higher in males than in females

Asthma medication in Finnish Olympic Athletes : No signs of overuse of inhaled β2-agonists.

Introduction: Occurrence of asthma has been reported to be frequent in endurance athletes and especially high in winter sport athletes. Recently, the International Olympic Committee has restricted the use of inhaled [beta]2-agonists and requires documentation for their use. However, epidemiologic data comparing the use of antiasthmatic medication in different sport events are mostly missing. Methods: A cross-sectional questionnaire survey was carried out in 2002. All the athletes (N = 494) financially supported by National Olympic Committee comprised the study group. Of them, 446 (90.3%) filled in a structured questionnaire concerning asthma and allergies, use of medication, characteristics of sport activities, and smoking habits. A representative sample of Finnish young adults (N = 1 504) served as controls. Results: Physician-diagnosed asthma was more common in athletes as compared with controls (13.9% vs 8.4%). Use of any asthma medication was reported by 9.6% of the athletes and by 4.2% of the controls. No difference was observed in the frequency of asthma medication used by winter or summer sport athletes (10.0% vs 9.4%). Inhaled [beta]2-agonists were used by 7.4% and 3.0% of the athletes and controls, respectively. After adjusting for age, sex, and smoking, odds ratio with 95% confidence interval for use of any asthma medication was 0.69 (0.17-2.92) for motor skills demanding events, 1.87 (0.85-4.11) for speed and power sports, 3.00 (1.68-5.37) for team sports, and 4.16 (2.22-7.78) for endurance events as compared with controls. None of the athletes used antiasthmatic medication without physician diagnosis. Conclusions: The frequency of antiasthmatic medication is clearly lower than the occurrence of physician-diagnosed asthma in Finnish Olympic athletes. No evidence of overuse of inhaled [beta]2-agonists is found
