Predictors of quality of life in newly diagnosed melanoma and breast cancer patients.

BACKGROUND: Quality of life (QoL) is a multidimensional construct, and several psychosocial and medical factors can predict a patient's QoL. We investigated the impact of factors in the psychological stress processes on QoL 3 months after diagnosis of melanoma or breast cancer. PATIENTS AND METHODS: In consecutive melanoma and breast cancer patients with localized disease, cancer-specific social support, coping with cancer, personality trait anger expression, non-cancer stress, sociodemographic variables, cancer and treatment variables, and QoL (evaluated as self-reported psychological and physical symptoms, self-perceived QoL, and depression) were assessed with validated quantitative questionnaires. The associations between QoL and the other factors were investigated with multivariate methods. RESULTS: Only a few factors differed between melanoma and breast cancer, in terms of treatment modalities and gender. The amount of received social support was higher among breast cancer patients. The predicting power of psychological stress factors on all the QoL measures was strong, but differed between the treatment groups (surgery only versus adjuvant treatment). Psychosocial factors were the strongest predictors of QoL, not cancer type or treatment. Behavioral Escape-Avoidance coping was associated with worse QoL. However, non-cancer life stresses showed the strongest QoL-decreasing influence. QoL-enhancing factors, including social support, were seen clearly only within the breast cancer patients receiving adjuvant treatment. CONCLUSIONS: QoL of newly diagnosed cancer patients is highly associated with psychosocial factors. Non-cancer life stresses seem to be very important in the QoL of newly diagnosed cancer patients. Adjuvant treatment may comprise supportive psychosocial factors that enhance QoL in cancer.     

Decreased serum selenium and magnesium levels in drunkenness arrestees

Serum levels of selenium magnesium, copper, zinc and iron were studied in chronic drunkenness arrestees and a healthy control group. The mean serum concentrations of selenium and magnesium were both significantly lower (P less than 0.01) in drunkenness arrestees than in the control subjects. The mean alcohol intake was 190 g of absolute alcohol daily in drunkenness arrestees and 14 g in controls. The erythrocyte glutathione peroxidase concentrations of the study groups did not support poor selenium intake as a principal cause of low selenium concentration in the serum.     

Dental diseases and loss of teeth in a group of Finnish alcoholics: a radiological study

A total of 85 Finnish alcohol-dependent subjects and 53 controls were studied with panoramic radiography. The aim was to study the possible associations between prolonged alcohol consumption and dental health. The mean number of teeth, caries lesions, endodontic treatments, periapical lesions, marginal bone loss, and periodontal infrabony pockets was studied. The subjects met the diagnostic criteria of alcohol dependence as set out in DSM-IV and ICD-10. The control group comprised social drinking volunteers with an AUDIT score &#104 8. For the final results the subjects were divided into groups on the basis of sex and age. The social backgrounds of the subjects were similar, except for employment and smoking. The results show significantly fewer teeth and more caries in the alcoholic group. There was a tendency for the alcoholics <45 years of age to have more endodontically treated teeth than the controls, but no difference in the number of periapical lesions in endodontically treated teeth was found. Horizontal bone loss and the presence of calculus were more frequent in alcoholic men than in alcoholic women. Significantly more horizontal bone loss was observed in the group of alcoholic nonsmokers than in nonalcoholic nonsmokers. In the nonsmoking groups alcoholics had significantly more periodontal destruction than the nonsmoking controls. We conclude that radiological dental health among individuals dependent on alcohol is weakened by more caries, more horizontal bone loss, and more numerous vertical infrabony pockets than social drinkers.     

Selenium addition to fertilizers effectively increased the serum levels of this element in the Finnish population.

Eighteen women participated in a prospective study to assess the need for supplemental riboflavin after gastroplasty. Three groups of five patients received either a placebo or 0.6 or 1.2 mg riboflavin daily for up to 12 months, except during months 4 and 7 when all participants were given a “one-a-day” supplement containing 1.7 mg riboflavin. Dietary intakes of riboflavin decreased from 1.43 +/? 0.17 mg before the operation to 0.70 +/? 0.07 mg at 3 months, and then increased to 1.02 +/? 0.17 mg by 6 months. Even at 12 months, only 33% of the subjects had dietary intakes greater than or equal to 1.2 mg. All those with total intakes less than or equal to 1.7 mg at 3 months had impaired riboflavin status, as indicated by an erythrocyte gluthatione reductase activity coefficient greater than 1.40 and an erythrocyte riboflavin concentration less than 372 nmol/L. In contrast, 62% of the same subjects had urinary riboflavin excretion in the acceptable range. Supplemental intake of 1.7 mg riboflavin appeared to prevent tissue depletion in all subjects.     

Purchaser–provider splits in health care—The case of Finland

The purchaser–provider split (PPS) is a service delivery model in which third-party payers are kept organizationally separate from service providers. The operations of the providers are managed by contracts. One of the main aims of PPS is to create competition between providers. Competition and other incentive structures built into the contractual relationship are believed to lead to improvements in service delivery, such as improved cost containment, greater efficiency, organizational flexibility, better quality and improved responsiveness of services to patient needs. PPS was launched in Finland in the early 1990s but was not widely implemented until the early 2000s. Compared to other countries with PPS the development and implementation of PPS in Finland has been unusual. Firstly, purchasing is implemented at the level of municipalities, which means that the size of the Finnish purchasers is extremely small. Elsewhere purchasing is mostly implemented at the regional or national levels. Secondly, PPS is also applied to primary health care and A&E services while in other countries the services mainly include specialized health care and residential care for the elderly. Thirdly, PPS in health and social services is not regulated by any specific legislation, regulative mechanisms or guidelines. Instead it is regulated within the same framework as public procurement in general.     

Human leucocyte antigen and TNFalpha polymorphism association in microscopic colitis

OBJECTIVES: Coeliac disease (CD) is common in patients with microscopic colitis (MC). The human leucocyte antigen (HLA)-DR3-DQ2 haplotype is strongly associated with CD, and there is evidence for an association with MC. We analysed the genetic background of MC by assessing the haplotypes of HLA-DR3-DQ2 and HLA-DR4-DQ8. In addition, TNFalpha gene polymorphism (-308) associated with susceptibility to several autoimmune diseases was studied. METHODS: Eighty patients with MC including 29 with collagenous colitis (CC) and 51 with lymphocytic colitis (LC) were typed for HLA-DR3-DQ2, and HLA-DR4-DQ8 molecule encoding genes using either an allele-specific PCR, or hybridization with sequence-specific oligonucleotides. Duodenal biopsies (N=78) confirmed the diagnosis of CD in 15 (18.8%) patients. TNFalpha(308) alleles were analyzed in 78 patients with MC (27 with CC and 51 with LC). A control group of 3627 patients was used in the HLA study and 178 patients in the TNFalpha study. RESULTS: HLA-DR3-DQ2 haplotype was more frequent in patients with MC (43.8%) including both subgroups (LC, 44.8%; CC, 43.1%; P<0.001), and MC with CD (86.7%; P<0.001) and without CD (33.3%; P=0.003), compared with the controls (18.1%). Similarly, the TNF2 carrier rate was higher in MC (46.2%; P<0.001) including both CC (44.4%; P=0.031) and LC (47.1%; P=0.001), and both MC patients with CD (66.7%; P=0.001) and without CD (39.3%; P=0.019), compared with the controls (23%). CONCLUSION: Both CC and LC are associated with the HLA-DR3-DQ2 haplotype and with TNF2 allele carriage. These associations are present also in MC patients without CD. The shared predisposing HLA-DR3-DQ2 haplotype and the high prevalence of CD in patients with MC suggest an epidemiological overlap, and probably some similarities in the pathogenesis of CD and MC.     

Cardiac arrest and left ventricular fibrosis in a Finnish family with the lamin A/C mutation

Introduction: We screened the candidate genes from a Finnish family in which the mother was resuscitated from ventricular fibrillation and the daughter died suddenly without any prior cardiac symptoms.
Methods and Results: In addition to screening of potential structural gene mutations, phenotyping of the proband and medico-legal autopsy of the victim of the sudden death, including histopathological examinations, were performed. Genetic screening revealed an R541C mutation in the lamin A/C gene both in the proband and her daughter. None of the 16 first- or second-degree relatives, or 96 unrelated healthy subjects, carried the same mutation. In the proband, the size and the global function of the left ventricle (LV) were normal, but a local hypokinesia and thinning of inferoposterior area of the LV were seen in 2D echocardiography and magnetic resonance imaging. Coronary angiogram and the results of the electrophysiological study were normal. Autopsy of the victim of sudden death showed localized thinning and fibrosis in the inferoposterior area of the LV, with only minimal fibrosis in the right ventricle and no abnormalities in the interventricular septum.
Conclusion: These observations indicate that a fatal or near-fatal cardiac arrhythmia can be the first clinical manifestation of a "de novo" mutation R541C of the lamin A/C gene. Replacement of cardiac myocytes by fibrosis seems to be the predominant pathologic-anatomic finding.     

Plasma asymmetric dimethylarginine and hyperemic myocardial blood flow in young subjects with borderline hypertension or familial hypercholesterolemia

OBJECTIVE: The goal of this study was to examine the relationship between plasma asymmetric dimethylarginine (ADMA) level and hyperemic myocardial blood flow (MBF) in subjects with borderline hypertension (BHT) and familial hypercholesterolemia (FH). METHODS: Asymmetric dimethylarginine is an endogenous competitive inhibitor of nitric oxide synthase that may modulate vascular function.We measured plasma ADMA levels and myocardial flow in 77 young men (mean age 35 +/- 5 years), including 47 healthy controls, 16 men with BHT, and 14 men with FH. Basal and dipyridamole-induced myocardial flow was measured using positron emission tomography. Plasma ADMA levels were measured using high-pressure liquid chromatography. RESULTS: Asymmetric dimethylarginine levels were significantly elevated in the BHT group compared with controls (0.59 +/- 0.13 micromol/l vs. 0.43 +/- 0.12 micromol/l, p < 0.001), and they had significantly lower dipyridamole flow (2.85 +/- 1.20 ml/min/g vs. 3.69 +/- 1.68 ml/min/g, p < 0.05). In a multivariate regression model adjusted for the study group, dipyridamole flow was inversely associated with ADMA (p < 0.05), age (p < 0.05), and apolipoprotein B concentration (p < 0.05). CONCLUSIONS: We conclude that plasma ADMA concentration is related to dipyridamole-induced vasodilatory function in young men, independently of blood pressure elevation and hypercholesterolemia. Subjects with BHT have significantly increased plasma ADMA levels, which may partly explain the impaired hyperemic MBF in this condition.
