Factors associated with health-related quality of life in patients and significant others one month after coronary artery bypass grafting

AIM

To describe and compare the health-related quality of life of patients and their significant others and to identify factors associated with health-related quality of life one month after coronary artery bypass surgery.

BACKGROUND

Heart disease and coronary artery bypass surgery affect the life of patients and their significant others. Following surgery, some patients might feel their quality of life is poor. Significant others are a major source of support for patients; therefore, it is important to know how their health-related quality of life is affected.

METHODS

This study is part of a major longitudinal research project. The questionnaire data for the study were collected one month after the surgical procedure from 270 patients and 240 significant others at one Finnish university hospital. Data analysis was by descriptive and inferential statistics. Stepwise linear regression analysis was used as a multivariate method.

RESULTS

Coronary artery bypass grafting patients had a poorer health-related quality of life than both the age and gender-standardised general population and their significant others. Significant others, on the other hand, had the same health-related quality of life as the general population. In patients, health-related quality of life was associated with the occurrence of cardiac symptoms and New York Heart Association class; in significant others, it was explained by chronic illnesses, employment, gender and emotional support received from members of the support network.

CONCLUSION

In the early stages of recovery, the health-related quality of life of coronary artery bypass grafting patients is inferior to that of the general population. There are also differences in the health-related quality of life of patients and their significant others.

RELEVANCE TO CLINICAL PRACTICE

Postcoronary artery bypass grafting rehabilitation programmes should provide support for both patients and significant others through networks that involve both professionals and peer supporters.

Continuity, comorbidity and longitudinal associations between depression and antisocial behaviour in middle adolescence: A 2-year prospective follow-up study

The study investigated continuity, comorbidity and longitudinal associations between depression Beck depression inventory (RBDI) and antisocial behaviour Youth self-report (YSR) in middle adolescence. Data were used from a community sample of 2070 adolescents who participated in a 2-year prospective follow-up study. The results indicate that both depression and antisocial behaviour had considerable continuity, and concurrent comorbidity between these disorders was strong. In contrast to several previous studies, antisocial behaviour did not predict subsequent depression, but conversely, depression predicted subsequent antisocial behaviour among girls. Among boys history of depression seemed to protect from subsequent antisocial behaviour. Gender differences in longitudinal associations are discussed.

Genetic study between SIRT1, PPARD, PGC-1alpha genes and Alzheimer's disease

Single nucleotide polymorphisms (SNPs) in three diabetes-related genes (SIRT1, PPARD, PGC-1alpha) were investigated with a case-control approach. To examine the genetic association of those genes with Alzheimer's disease (AD) risk, we used the TaqMan technique to genotype five SNP sites for SIRT1, six for PPARD and eight for the PGC-1alpha gene, in 326 Finnish AD cases and 463 controls and conducted a single allele and genotypic distribution comparison as well as estimated haplotype frequencies between cases and controls. No significant differences in AD risk were found in single SNP and haplotype analyses for any of the three genes between 326 cases and 463 controls. However, in a subgroup of women older than 65 years, the frequencies of three SNPs in the SIRT1 gene were significantly different between AD and controls. We conclude that there is no real association with SNPs available in the present study between SIRT1, PPARD or PGC-1alpha genes and AD risk in the Finnish population.

Diet does not explain the high prevalence of dyslipidaemia in paediatric renal transplant recipients

Dyslipidaemia exists frequently after renal transplantation (RTx) and promotes atherosclerosis. In this study, we examined the association between daily intake of nutrients and serum lipids after paediatric RTx. We studied 45 children with acceptably functioning kidney grafts and adequately completed food records at a median age of 10.6 years (range 4.3-17.2 years), a median 5.2 years (range 1.0-11.0) after RTx, and 178 healthy controls at a median age of 9.0 years (range 3.2-18.7 years). Serum total cholesterol (TC), triglyceride, and apolipoprotein B concentrations were higher in the RTx patients than in the controls (P < 0.001), despite similar dietary intakes of saturated and polyunsaturated fats, and cholesterol. Both the RTx patients and controls ingested a low amount of polyunsaturated fats [mean (SD) percent of total calories (E%) 4.8 (1.3) and 4.6 (1.5), respectively] and an excessive amount of saturated fats [mean (SD) E% 14.4 (2.4) and 14.1 (2.8), respectively]. In multiple regression analyses, dietary fibre was negatively associated with serum TC concentration. The standard deviation score for body mass index was negatively associated with serum concentration of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein diameter, and positively with serum triglyceride concentration. In addition, dietary total fat intake was positively associated with serum HDL-C. In conclusion, the higher prevalence of dyslipidaemia in our paediatric RTx patients than in the controls was not explained by the diet. However, the type of fat consumed implicates the counselling for a healthier dietary lifestyle, with an increase in the ingestion of polyunsaturated fats and a decrease in that of saturated fats.

Predicting lifetime mood elevation in primary care patients and psychiatric patients

Unipolar depression is undoubtedly the most common affective disorder, but recently the role of bipolar disorders has become more and more significant. The aim of the study was to improve the detection of mood elevations by careful anamnestic assessment, especially family history and psychosocial functional skills. A sample, screened for depression, of 430 primary care patients and 423 psychiatric patients aged 18-64 were interviewed in 1991-1992 using the Present State Examination. Anamnestic information was obtained by questionnaire and interview. Participants were re-contacted in 1998-1999. Experienced lifetime mood elevation was assessed in the follow-up study using the main criteria of the ICD-10 in a telephone interview by three research psychiatrists. Patient's smoking, suicidality in the Hamilton Depression Scale (HAM-D), problems in making contact with the opposite sex when a teenager, and mental problems in either of the parents when the patient was < or = 15 years were associated with experienced lifetime mood elevation. Quick and easy questions about smoking and difficulties in making contact with the opposite sex may improve the detection of mood elevation.

Age and gender differences in social anxiety symptoms during adolescence: the Social Phobia Inventory (SPIN) as a measure

The aim of the present study was to examine age and gender differences in social anxiety symptoms during adolescence, and to investigate the psychometrics of the Social Phobia Inventory (SPIN) among adolescents. The SPIN was administered to a large general population sample (n=5252) of Finnish adolescents aged 12-16 years. Age and gender trends in scores and internal consistency and factorial composition of the SPIN were examined in this sample. The test-retest reliability of the SPIN was examined in a smaller sample of adolescents (n=802). Results showed that girls scored higher than boys on the SPIN full scale and three subscales across the whole age range. Eighth graders (14- to 15-year-olds) scored higher than seventh and ninth graders on the full scale, for boys the differences were significant. Good test-retest reliability (r=0.81), and internal consistency (alpha=0.89) were found for the SPIN. An exploratory factor analysis (EFA) performed on a random half (n=2625) of the population sample yielded a one-factor model accounting for 38% of the variance between items. This one-factor model, plus an alternative three-factor model, were examined in the holdout half of the population sample (n=2627) by means of a confirmatory factor analysis (CFA). Some support was gained for both factor structures. Our results indicate that symptoms of social phobia may increase in mid-adolescence. The SPIN appears to be a reliable self-report instrument among adolescents.

Screening of mutations in the PHF8 gene and identification of a novel mutation in a Finnish family with XLMR and cleft lip/cleft palate

We investigated the prevalence of mutations in the PHD finger protein 8 (PHF8) gene in X-linked mental retardation (XLMR) and facial cleft starting from the original cohort of 7712 patients operated on since 1 January 1950 for cleft lip/cleft palate in the Cleft Centre at the Helsinki University Hospital. From this nationwide material, 18 patients including one family with two male patients with cleft lip/cleft palate and unknown cause of mental retardation (MR) were sequenced for the coding regions and splice sites of the PHF8 gene. A novel missense mutation c.836C>T of the PHF8 gene was identified in a Finnish family with multiple-affected male patients. The mutation resides in exon 8 and changes phenylalanine to serine (F279S) in the functionally important Jmonji C domain of the protein. The clinical phenotype of the male patients was characterized by mild MR, mild dysmorphic features, unilateral cleft lip and cleft palate in one and bilateral cleft lip and cleft palate in the other sibling. The mutation was not present in 200 anonymous blood donors (approximately 300 X-chromosomes). To our knowledge, F279S is the third mutation of the PHF8 gene identified so far.

Depression and school performance in middle adolescent boys and girls

The study aimed to investigate the associations between different levels of depression with different aspects of school performance. The target population included 2516 7th-9th grade pupils (13-17 years) of whom 90% completed the questionnaire anonymously in the classroom. Of the girls 18.4% and of the boys 11.1% were classified as being depressed (R-Beck Depression Inventory (BDI), the Finnish version of the 13-item BDI). The lower the self-reported grade point average (GPA) or the more the GPA had declined from the previous term, the more commonly the adolescents were depressed. Depression was associated with difficulties in concentration, social relationships, self-reliant school performance and reading and writing as well as perceiving schoolwork as highly loading. The school performance variables had similar associations with depression among both sexes when a wide range of depression was studied but gender differences appeared when studying the severe end of the depression scale. Our study indicates that pupils reporting difficulties in academic performance should be screened for depression.

A 15-year national follow-up: legislation is not enough to reduce the use of seclusion and restraint

BACKGROUND

Seclusion and restraint are frequent but controversial coercive measures used in psychiatric treatment. Legislative efforts have started to emerge to control the use of these measures in many countries. In the present study, the nationwide trends in the use of seclusion and restraint were investigated in Finland over a 15-year span which was characterised by legislative changes aiming to clarify and restrict the use of these measures.

METHOD

The data were collected during a predetermined week in 1990, 1991, 1994, 1998 and 2004, using a structured postal survey of Finnish psychiatric hospitals. The numbers of inpatients during the study weeks were obtained from the National Hospital Discharge Register.

RESULTS

The total number of the secluded and restrained patients declined as did the number of all inpatients during the study weeks, but the risk of being secluded or restrained remained the same over time when compared to the first study year. The duration of the restraint incidents did not change, but the duration of seclusion increased. A regional variation was found in the use of coercive measures.

CONCLUSION

Legislative changes solely cannot reduce the use of seclusion and restraint or change the prevailing treatment cultures connected with these measures. The use of seclusion and restraint should be vigilantly monitored and ethical questions should be under continuous scrutiny.

The Depression Scale as a screening instrument for a subsequent depressive episode in primary healthcare patients

BACKGROUND

There are numerous instruments for screening for depression. A feasible screen is good at both recognising and predicting depression.

AIMS

To study the ability of the Depression Scale and its items to recognise and predict a depressive episode.

METHOD

A sample of patients attending primary care was examined in 1991-992 and again 7 years later. The accuracy of the Depression Scale at baseline and at follow-up was tested against the Short Form of the Composite International Diagnostic Interview (CIDI-SF) diagnosis of depression at follow-up. The sensitivity and specificity of the Depression Scale and its items were assessed.

RESULTS

Both baseline and follow-up Depression Scale scores were consistent with the CIDI-SF diagnoses. It was possible to find single items efficient at both recognising and predicting depression.

CONCLUSIONS

The Depression Scale is a useful screening instrument for depression, with both diagnostic and predictive validity.

Effectiveness of hip or knee replacement surgery in terms of quality-adjusted life years and costs

BACKGROUND

Concurrent head-to-head comparisons of healthcare interventions regarding cost-utility are rare. The concept of favorable cost-effectiveness of total hip or knee arthroplasty is thus inadequately verified.

PATIENTS AND METHODS

In a trial involving several thousand patients from 10 medical specialties, 223 patients who were enrolled for hip or knee replacement surgery were asked to fill in the 15D health-related quality of life (HRQoL) survey before and after operation.

RESULTS

Mean (SD) HRQoL score (on a 0-1 scale) increased in primary hip replacement patients (n = 96) from 0.81 (0.084) preoperatively to 0.86 (0.12) at 12 months (p < 0.001). In revision hip replacement (n = 24) the corresponding scores were 0.81 (0.086) and 0.82 (0.097) respectively (p = 0.4), and in knee replacement (n = 103) the scores were 0.81 (0.093) and 0.84 (0.11) respectively (p < 0.001). Of 15 health dimensions, there were statistically significant improvements in moving, usual activities, discomfort and symptoms, distress, and vitality in both primary replacement groups. Mean cost per quality-adjusted life year (QALY) gained during a 1-year period was euro 6,710 for primary hip replacement, euro 52,274 for revision hip replacement, and euro 13,995 for primary knee replacement.

INTERPRETATION

Hip and knee replacement both improve HRQoL. The cost per QALY gained from knee replacement is twice that gained from hip replacement.

Psychosocial functioning needs attention in adolescent eating disorders

We studied the differences in psychosocial functioning in the early stages of adolescent anorexia nervosa (AN) and bulimia nervosa (BN). The study group comprised 57 adolescent eating disorder (ED) outpatients (girls). Psychosocial functioning was evaluated by GAF (Global Assessment of Functioning), and by Morgan-Russell psychosocial subscales. GAF scores were very low in both AN and BN. On the Morgan-Russell subscales, bulimics reported more unsatisfactory relationships with family and impairment in work/school. Anorectics tended to have more difficulties in emancipation from family and in social contacts. Multivariate analysis showed associations of BN and high GSI with difficulties in relationships with family and of AN with difficulties in emancipation from family and with fewer social activities. Longer duration of illness predicted best impaired working ability. In adolescent EDs, psychosocial functioning is markedly impaired. We emphasize the importance of evaluating psychosocial functioning at the very onset of ED.

Bone mineral density is reduced in brain tumour patients treated in childhood

AIM

To determine the prevalence of low bone mineral density among children surviving brain tumours and to identify possible factors underlying impaired bone health.

METHODS

Cross-sectional study; total body bone mineral density (TBBMD), fat mass (FM) and lean body mass (LBM) were measured by dual-energy X-ray absorptiometry (DXA) in 46 brain tumour patients aged from 3.8 to 28.7 y (mean 14.9 y) treated in childhood 1.4-14.8 y (mean 6.4 y) after end of treatment for brain tumour. Low bone mineral density was defined as TBBMD z score < - 2.0.

RESULTS

Fifteen patients had TBBMD z scores < - 2.0, indicating a 33% prevalence of low bone density. The TBBMD z score ranged from -5.7 to 0.6 (mean -1.7). Out of several potential factors, only combined craniospinal irradiation was significantly associated with low z score (p=0.034, according to multiple regression analysis), while exclusive cranial irradiation showed a borderline statistical association (p=0.100, according to multiple regression analysis).

CONCLUSION

One third of brain tumour patients treated in childhood had reduced bone mineral density. The reasons for this condition are apparently multifactorial, including craniospinal irradiation.

Cost-utility of routine cataract surgery

Background

If decisions on health care spending are to be as rational and objective as possible, knowledge on cost-effectiveness of routine care is essential. Our aim, therefore, was to evaluate the cost-utility of routine cataract surgery in a real-world setting.

Methods

Prospective assessment of health-related quality of life (HRQoL) of patients undergoing cataract surgery. 219 patients (mean (SD) age 71 (11) years) entering cataract surgery (in 87 only first eye operated, in 73 both eyes operated, in 59 first eye had been operated earlier) filled in the 15D HRQoL questionnaire before and six months after operation. Direct hospital costs were obtained from a clinical patient administration database and cost-utility analysis performed from the perspective of the secondary care provider extrapolating benefits of surgery to the remaining statistical life-expectancy of the patients.

Results

Mean (SD) utility score (on a 0–1 scale) increased statistically insignificantly from 0.82 (0.13) to 0.83 (0.14). Of the 15 dimensions of the HRQoL instrument, only seeing improved significantly after operation. Mean utility score improved statistically significantly only in patients reporting significant or major preoperative seeing problems. Of the subgroups, only those whose both eyes were operated during follow-up showed a statistically significant (p < 0.001) improvement. Cost per quality-adjusted life year (QALY) gained was €5128 for patients whose both eyes were operated and €8212 for patients with only one eye operated during the 6-month follow-up. In patients whose first eye had been operated earlier mean HRQoL deteriorated after surgery precluding the establishment of the cost per QALY.

Conclusion

Mean utility gain after routine cataract surgery in a real-world setting was relatively small and confined mostly to patients whose both eyes were operated. The cost of cataract surgery per quality-adjusted life year gained was much higher than previously reported and associated with considerable uncertainty.

Cost-utility analysis of routine neurosurgical spinal surgery

OBJECT

Cost-utility analysis is currently the preferred method with which to compare the cost-effectiveness of various interventions. The authors conducted a study to establish the cost-utility results of routine neurosurgery-based spinal interventions by examining patient-derived values.

METHODS

Two hundred seventy patients undergoing surgery for cervical or lumbar radicular pain filled in the 15-dimensional health-related quality of life (HRQOL) questionnaire before and 3 months after surgery. Quality-adjusted life years (QALYs) were calculated using the utility data and the expected remaining life years of the patients. The mean HRQOL score (scale, 0-1) increased after cervical surgery (169 patients, mean age 52 years, 40% women) from 0.81 +/- 0.11 preoperatively, to 0.85 +/- 0.11 at 3 months, and after lumbar surgery (101 patients, mean age 54 years, 59% women) from 0.79 +/- 0.10 preoperatively, to 0.85 +/- 0.12 at 3 months (p < 0.001). Of the 15 dimensions of health, improvement in the following was documented in both groups: sleeping, usual activities, discomfort and symptoms, depression, distress, vitality, and sexual activity (p < 0.05). The cost per QALY gained was Euro 2774 and 1738 for cervical and lumbar operations, respectively. In cases in which surgery was delayed the cost per QALY was doubled.

CONCLUSIONS

Spinal surgery led to a statistically significant and clinically important improvement in HRQOL. The cost per QALY gained was reasonable, less than half of that observed, for example, for hip replacement surgery or angioplasty treatment of coronary artery disease; however, a prolonged delay in surgical intervention led to an approximate doubling of the cost per QALY gained by the treatment.

Laboratory parameters predictive of developing necrotizing enterocolitis in infants born before 33 weeks of gestation

PURPOSE

The aim of this study was to identify laboratory findings predictive of necrotizing enterocolitis (NEC).

METHODS

Prospective follow-up of 140 infants of less than 33 weeks of gestation. Twenty-six infants developed NEC (grades I to III, criteria of Bell et al [Ann Surg 1978;187:1-7]) (NEC group). For each, 2 birth-weight, gestational age- and postnatal age-matched controls were selected (control group). Blood counts, glucose and electrolyte levels, C-reactive protein, and acid-base balance 3 days, 2 days, and 1 day before and at the onset of NEC and at corresponding ages from the controls were recorded.

RESULTS

Metabolic acidosis occurred, the platelet levels decreased, and the blood glucose increased on successive days in the infants with grade NEC II-III. At the onset of NEC, the infants had significantly lower platelet and higher blood glucose levels compared with controls. More than half of infants with intestinal perforation had leukocyte levels above 30 x 10(9)/L and pH less than 7.25, and their mean blood glucose levels increased to more than 1.5 mmol/L in 24 hours. The remaining parameters were not useful.

CONCLUSION

A persistent metabolic acidosis, decreasing platelet, and increasing blood glucose level on several successive days might predict a developing NEC, and leukocyte values above 30 x 10(9)/L, pH less than 7.25, and a blood glucose rise by 1.5 mmol/L or more within 24 hours predict NEC with intestinal perforation. Such findings should alert the physician to look for signs of NEC in a preterm infant.

Subjective life satisfaction and living situations of persons in Finland with long-term schizophrenia

OBJECTIVE

This study measured subjective life satisfaction among patients with long-term schizophrenia who were living in the community.

METHODS

A representative national sample of 2,221 persons with schizophrenia who were discharged from psychiatric hospitals in Finland in 1986, 1990, and 1994 were interviewed three years after discharge. Subjective life satisfaction was measured; patients were asked about their current level of satisfaction and the level of satisfaction they recalled having at the time of discharge.

RESULTS

Patients tended to report more satisfaction at follow-up if they were female, had good psychosocial functioning, had several confidants, or were living in group homes or dormitories. Patients tended to be less satisfied at follow-up if they were divorced or had mental and physical symptoms. Patients with depressive symptoms or with low psychosocial functioning and those who were currently hospitalized reported the smallest changes in levels of satisfaction between the two time points. Patients with low psychosocial functioning who were living with their parents, in group homes or dormitories, or in institutions were relatively satisfied, whereas patients with good psychosocial functioning were more satisfied if they lived with their spouse or partner.

CONCLUSIONS

Being female and having good psychosocial functioning, confidants, good physical health, and living arrangements in the community that offer support corresponding to the patient's psychosocial state are important factors of life satisfaction among patients with long-term schizophrenia.

Bilateral notching of uterine arteries at 12-14 weeks of gestation for prediction of hypertensive disorders of pregnancy

OBJECTIVE

To assess the value of transvaginal uterine artery Doppler ultrasound at 12--14 weeks of gestation in predicting hypertensive disorders of pregnancy in high-risk women.

METHODS

One hundred and twenty high-risk women were evaluated prospectively by Doppler ultrasound of uterine and umbilical arteries at 12--14 weeks of gestation. The presence of bilateral notches, resistance and pulsatility index (PI), mean and maximum flow velocities of uterine arteries, and resistance and PI of umbilical arteries were investigated. Those with bilateral notching were randomized to acetylsalicylic acid (n=43) or placebo groups (n=43) and were followed up twice during pregnancy with the same ultrasound measurements. The women without bilateral notches (n=29) served as controls. In this study, we compared 43 women in the placebo group to 29 controls without bilateral notches. The outcome measures were pregnancy-induced hypertension, pre-eclampsia and intrauterine growth restriction.

RESULTS

The sensitivity of bilateral notching in predicting hypertensive disorders of pregnancy decreased with advancing pregnancy from 91 to 35%, and the specificity and the positive predictive values increased from 41 to 94% and from 7 to 70%, respectively. The negative predictive values ranged from 86 to 97%.

CONCLUSION

Bilateral notching of uterine arteries at 12--14 weeks is a useful tool in predicting the development of hypertensive disorders in high-risk pregnancies. It is also a suitable test for surveillance of high-risk pregnancies.

Apolipoprotein E polymorphism is not a predictor for repeated coronary artery bypass surgery

OBJECTIVES

Factors leading to the occlusion of coronary grafts are diverse and may at least partially be inherited. We aimed to study the possible genetic predisposition and especially the role of apoE epsilon4 allele as a risk factor for repeated coronary artery bypass grafting (CABG) in a case-control setting.

DESIGN

All patients (n=184) who underwent repeated CABG between 1990 and 1998 were identified in the computed registry of the Department of Cardiothoracic Surgery in Tampere University Hospital. Age, sex and operation date matched controls with first time CABG were selected from the same registry. DNA samples were collected by sample stick sent via the mail for buccal smear. The final analysis included 137 surviving matched pairs.

RESULTS

In patients <62 years of age (median age), family history emerged as the only significant (OR=3.4; 95% CI=1.5-7.8, p=0.004) predictor for repeated surgery. Among older patients, repeated CABG was no longer predicted by family history but by hypercholesterolemia (OR=2.1; 95% CI=1.1-4.0, p=0.027), modified by apoE genotype.

CONCLUSIONS

Our results suggest that medium-term survivors after redo CABG have a strong genetic predisposition unrelated to hypercholesterolemia or apoE genotype, leading to more severe coronary artery disease at earlier age. In the older age group, redo coronary artery bypass surgery is associated with hypercholesterolemia, which, although modified by apoE genotype, may mainly be due to other genetic or acquired factors.

Psychopathological distress predicts suicidal ideation and self-harm in adolescent eating disorder outpatients

OBJECTIVE

This study evaluated the differences in suicidal behaviour between adolescent anorexia nervosa (AN) and bulimia nervosa (BN), and the association of age, menarche timing, duration of eating disorder (ED), depression and general psychopathological symptoms (GSI) with suicidal behaviour in adolescent ED.

METHODS

The study group comprised 57 adolescent outpatients (girls) attending for assessment because of eating disorders. Suicidal ideation, deliberate self-harm and suicidal attempts were assessed in self-report questionnaires.

RESULTS

In both ED groups, one adolescent had attempted suicide before assessment. Suicidal ideation and/or deliberate self-harm were reported in over half of the cases. Bulimics had significantly more suicidal ideation and deliberate self-harm than anorectics. In multivariate analysis, BN and depression predicted suicidal ideation, but only GSI persisted as predicting deliberate self-harm.

CONCLUSIONS

Suicidal behaviour is common in adolescent ED. Type of ED (BN), depression and higher GSI are strongly associated with suicidal ideation and deliberate self-harm. Our results point to the need to evaluate psychopathological symptoms in adolescent ED, especially in BN, in the initial assessment to prevent severe suicidal behaviour.
