OBJECTIVE: A common polymorphism (-1C to T) in the translation initiation sequence of annexin A5 (ANV) gene has recently been associated with a decreased risk of acute myocardial infarction (AMI). The aim of the present study was to analyze the association between the ANV genepolymorphism and the risk of AMI and ischemic sudden cardiac death (SCD) in middle-aged Finnish males. MATERIAL AND METHODS: A case-control study involving three distinct groups of subjects was carried out: (1) victims of SCD (n=98), (2) survivors of AMI (n=212), and (3) randomly selected control subjects without any history of coronary heart disease (n=243). The ANV polymorphism was genotyped in each study group. RESULTS: Among the control group of healthy Finnish males the prevalence rates of the CC, CT, and TT genotypes were 83.1%, 15.2%, and 1.6%, respectively. Among the survivors of AMI, the prevalence rates of CC, CT, and TT were 79.7%, 20.3%, and 0%, respectively, and among the victims of SCD 83.7%, 16.3%, and 0%, respectively. No significant differences in the genotype or allele distributions were observed between the study groups. CONCLUSION: The -1C to T polymorphism in the ANV gene is not associated with the risk of AMI or SCD in middle-aged Finnish males.
This article summarizes the current status of 1H MRS in detecting and quantifying a boron neutron capture therapy (BNCT) boron carrier, L-p-boronophenylalanine-fructose (BPA-F) in vivo in the Finnish BNCT project. The applicability of 1H MRS to detect BPA-F is evaluated and discussed in a typical situation with a blood containing resection cavity within the gross tumour volume (GTV). 1H MRS is not an ideal method to study BPA concentration in GTV with blood in recent resection cavity. For an optimal identification of BPA signals in the in vivo 1H MR spectrum, both pre- and post-infusion 1H MRS should be performed. The post-infusion spectroscopy studies should be scheduled either prior to or, less optimally, immediately after the BNCT. The pre-BNCT MRS is necessary in order to utilise the MRS results in the actual dose planning.
The prescription of analgesics and anti-inflammatory drugs (analgesics) was studied using computerized patient records from a Finnish health centre with a population base of some 27,000 inhabitants. A random sample of every fifth patient visiting the health centre in 1986 was chosen. This study sample consisted of 4,577 patients with 17,021 physician contacts and altogether 14,035 prescriptions during the 1-year follow-up: of these analgesics comprised 14.8%. The proportion of the study population who received at least one analgesic prescription was 23 +/- 1.2% (95% CI). The use of physician contacts as a base revealed 10.7 +/- 0.5% (95% CI) of the contacts with an analgesic prescription. The exposure to analgesics among males increased with age from 17% for those aged 15-34 years to 34% for those aged 75 years or more. Among women, exposure to analgesics increased from 17% (15-34 years) to 41% (75 years or more). Most of patients who received analgesic prescriptions were incidental users (one or two analgesic prescriptions per year). Only 4% of women and 3% of men were categorized as heavy users of analgesics (seven or more analgesic prescriptions per year). The proportion of heavy users increased with age and was highest in the oldest age-group (75 years or more). In order to make informed policy judgements about drug use in society, we need routine sales statistics and patient-specific drug-use data such as those presented in this paper.
A 2-year self-help manual smoking cessation intervention was conducted among a panel of middle-aged Finnish men (n = 265) who were recruited proactively in a longitudinal cardiovascular risk factor surveillance study.
Intervention utilized the stages of change concept of the transtheoretical model. The stages were assessed in the treatment condition at baseline of the cessation study and after that by mail every sixth month. Assessments were followed by an immediate mailing of a stage-based self-help manual matching the stage of change at that time. A usual care group was assessed annually but received no treatment.
Approximately 15% of colorectal cancers exhibit instability of short nucleotide repeat regions, microsatellites. These tumors display a unique clinicopathologic profile and the microsatellite instability status is increasingly used to guide clinical management as it is known to predict better prognosis as well as resistance to certain chemotherapeutics. A panel of five repeats determined by the National Cancer Institute, the Bethesda panel, is currently the standard for determining the microsatellite instability status in colorectal cancer. Recently, a quasimonomorphic mononucleotide repeat 16T/U at the 3' untranslated region of the Ewing sarcoma breakpoint region 1 gene was reported to show perfect sensitivity and specificity in detecting mismatch repair deficient colorectal, endometrial, and gastric cancers in two independent populations. To confirm this finding, we replicated the analysis in 213 microsatellite unstable colorectal cancers from two independent populations, 148 microsatellite stable colorectal cancers, and the respective normal samples by PCR and fragment analysis. The repeat showed nearly perfect sensitivity for microsatellite unstable colorectal cancer as it was altered in 212 of the 213 microsatellite unstable (99.5%) and none of the microsatellite stable colorectal tumors. This repeat thus represents the first potential single marker for detecting microsatellite instability.
OBJECTIVE: To follow the clinical course of patients with the mitochondrial DNA mutation 3243A>G for 3 years. METHODS: Thirty-three adult patients with the 3243A>G mutation entered a 3-year follow-up study. They were clinically evaluated annually, audiometry was performed, and samples were drawn for the analysis of blood chemistry and mutation heteroplasmy in leukocytes. Holter recording was performed three times during the follow-up and echocardiography, neuropsychological assessment, and quantitative EEG and brain imaging conducted at entry and after 3 years. RESULTS: The incidence of new neurologic events was low during the 3-year follow-up. Sensorineural hearing impairment (SNHI) progressed, left ventricular wall thickness increased, mean alpha frequency in the occipital and parietal regions decreased, and the severity of disease index (modified Rankin score) progressed significantly. The rate of SNHI progression correlated with mutation heteroplasmy in muscle. The increase in left ventricular wall thickness was seen almost exclusively in diabetic patients. Seven patients died during the follow-up, and they were generally more severely affected than those who survived. CONCLUSIONS: Significant changes in the severity of disease, sensorineural hearing impairment, left ventricular hypertrophy, and quantitative EEG were seen in adult patients with 3243A>G during the 3-year follow-up.
