677 C-->T polymorphism of the methylenetetrahydrofolate reductase gene and preeclampsia

OBJECTIVE: To evaluate C to T substitution at nucleotide 677 of N(5), N(10)-methylenetetrahydrofolate reductase gene in women with prior preeclamptic or normotensive pregnancies. METHODS: Methylenetetrahydrofolate reductase genotypes were determined in 113 Finnish women with preeclamptic first pregnancies and 103 controls with one or more normotensive pregnancies, using polymerase chain reaction and restriction enzyme analysis. Preeclampsia was defined as severe in 100 women who fulfilled one or more of the subsequent criteria: systolic blood pressure (BP) at least 160 mmHg, diastolic BP at least 110 mmHg, or proteinuria at least 2 g per 24-hour urine collection. RESULTS: There were no significant differences in prevalences of the methylenetetrahydrofolate reductase genotypes (CC, CT, and TT) between groups (57%, 40%, and 3% in the preeclamptic group and 54%, 39%, and 7%, respectively, in controls). The frequency of the T677 allele was 0.23 in the preeclamptic group and 0.26 in the control group (difference 0.03; 95% confidence interval -0.08, 0.14; P =.51). Our sample had 60% power to detect a difference of the allele frequencies similar to that (0.12) reported previously. The result was similar when analysis was restricted to patients with severe preeclampsia (T677 allele frequency 0.22). CONCLUSION: A carrier status for the T677 allele of the methylenetetrahydrofolate reductase gene does not predispose to preeclampsia, at least in the Finnish population.     

The first abortion - and the last? A study of the personality factors underlying repeated failure of contraception

The causes leading to a second abortion were outlined in a psychological study comparing 30 women expecting a second abortion with 29 women who had successfully prevented conception after a first abortion. It was found that both groups improved their contraceptive practices after the first abortion. However, while the latter group continued with their improved practices, the former group went back to the earlier inefficient or non-existent contraceptive behavior. The inability to improve contraception in the long run was not related to differences in educational level or knowledge about contraceptive techniques but to the developmental level of personality structures. The women expecting their second abortion rated lower in control of impulsivity, emotional balance, realism, self-esteem and stability of life as well as capacity for more integrated personal relationships. The differences in personality development and consequently in the capacity for long-term contraception were found to be due to growth conditions in childhood.     

Non-synonymous sequence variants within the oxygen-dependent degradation domain of the <Emphasis Type="Italic">HIF1A</Emphasis>gene are not associated with pre-eclampsia in the Finnish population

Background  

Reduced placental perfusion predisposes to the maternal syndrome pre-eclampsia characterized by systemically reduced perfusion. Considerable data support the role of angiogenic factors in the development of the maternal syndrome. Hypoxia-inducible factor (HIF-1) mediates the cellular responses to hypoxia e.g. by promoting angiogenesis.     

gyrA polymorphism in Campylobacter jejuni: detection of gyrA mutations in 162 C. jejuni isolates by single-strand conformation polymorphism and DNA sequencing

Mutations in the quinolone resistance-determining region of the gyrA gene from 138 ciprofloxacin-resistant (MIC, > or =4 microg/ml) and 24 ciprofloxacin-susceptible (MIC, < or =1 microg/ml) clinical Campylobacter jejuni isolates were subjected to single-strand conformation polymorphism analysis and sequencing. All of the isolates could be assigned to three genotypic clusters based on silent mutations. All resistant isolates had a point mutation at codon 86.     

Patient participation in patient safety still missing: Patient safety experts' views

The aim of this study was to elicit patient safety experts' views of patient participation in promoting patient safety. Data were collected between September and December in 2014 via an electronic semi‐structured questionnaire and interviews with Finnish patient safety experts (n = 21), then analysed using inductive content analysis. Patient safety experts regarded patients as having a crucial role in promoting patient safety. They generally deemed the level of patient safety as ‘acceptable’ in their organizations, but reported that patient participation in their own safety varied, and did not always meet national standards. Management of patient safety incidents differed between organizations. Experts also suggested that patient safety training should be increased in both basic and continuing education programmes for healthcare professionals. Patient participation in patient safety is still lacking in clinical practice and systematic actions are needed to create a safety culture in which patients are seen as equal partners in the promotion of high‐quality and safe care.     

Liver fat in the metabolic syndrome

BACKGROUND: The liver, once fatty, overproduces components of the metabolic syndrome, such as glucose and lipids. The amount of liver fat in subjects with and without the metabolic syndrome has not been determined. It is unknown which clinically available markers best reflect liver fat content. MEASUREMENTS: Components of the metabolic syndrome as defined by the International Diabetes Federation and liver fat content by proton magnetic resonance spectroscopy were measured in 271 nondiabetic subjects (162 women, 109 men). In addition, other features of insulin resistance (serum insulin, C-peptide), intraabdominal and sc fat by magnetic resonance imaging, and liver enzymes (serum alanine aminotransferase and serum aspartate aminotransferase) were measured. RESULTS: Liver fat was 4-fold higher in subjects with [n = 116; median 8.2% (interquartile range 3.2-18.7%)] than without [n = 155; 2.0% (1.0-5.0%); P < 0.0001] the metabolic syndrome. This increase in liver fat remained significant after adjusting for age, gender, and body mass index. All components of the metabolic syndrome correlated with liver fat content. The best correlate was waist in both women (r = 0.59, P < 0.0001) and men (r = 0.56, P < 0.0001). Liver fat correlated significantly with serum alanine aminotransferase (r = 0.39, P < 0.0001 for women; r = 0.44, P < 0.0001 for men) and aspartate aminotransferase (r = 0.27, P = 0.0005 for women; r = 0.31, P = 0.0012 for men) concentrations. The best correlates of liver fat were fasting serum insulin (r = 0.61; P < 0.0001 for both women and men) and C-peptide (r = 0.62; P < 0.0001 for both women and men). CONCLUSIONS: Liver fat content is significantly increased in subjects with the metabolic syndrome as compared with those without the syndrome, independently of age, gender, and body mass index. Of other markers, serum C-peptide is the strongest correlate of liver fat.     

Reductions in postdischarge suicide after deinstitutionalization and decentralization: a nationwide register study in Finland

OBJECTIVE: This study analyzed trends in suicides occurring after a psychiatric hospitalization during more than a decade of significant structural changes in mental health services in Finland-that is, deinstitutionalization, downsizing of inpatient care, and decentralization. METHODS: Retrospective register data on completed suicides and psychiatric inpatient treatments were collected for the periods 1985-1991 and 1995-2001, representing service provision before and after significant structural changes. The data were used to produce an estimate for a change in postdischarge suicide risk. RESULTS: In both periods, a fifth of suicide victims had been psychiatrically hospitalized within the preceding year. Among persons hospitalized, the risk of suicide was greater in 1985-1991 than in 1995-2001 for both one week after discharge (risk ratio [RR]=1.50, 95% confidence interval [CI]=1.38-1.62) and one year after discharge (RR=1.25, CI=1.19-1.30). When types of disorders were analyzed separately, the relative risk of suicide one year postdischarge for those hospitalized in the earlier period was greater for patients with schizophrenia (RR=1.26, CI=1.17-1.36) and patients with affective disorders (RR=1.60, CI=1.48-1.73). In parallel with general development of inpatient psychiatric services, in 1995-2001 the inpatient treatment periods preceding suicides were significantly shorter (a mean+/-SD of 45+/-340 days in 1995-2001, compared with a mean of 98+/-558 days in 1985-1991), the number of individual patients treated in the hospital for schizophrenia spectrum disorders was lower (26% compared with 36%), and the number treated for affective disorders was higher (45% compared with 35%). CONCLUSIONS: The restructuring and downsizing of mental health services was not associated with any increase in suicides immediately (one week) or one year postdischarge. Instead, the risk of these suicides decreased significantly between the two time periods among several diagnostic categories. Although the role of psychiatric hospitalization in general may have changed over time, patients who are hospitalized now may be less suicidal after discharge. Our results indicate, in terms of postdischarge suicides, that the downsizing of psychiatric hospitals has been a success. However, there is still a substantial need for better recognition of suicidal risk among psychiatric patients.     

Differences in the clinical characteristics of adolescent depressive disorders

Our objective was to analyze differences in clinical characteristics and comorbidity between different types of adolescent depressive disorders. A sample of 218 consecutive adolescent (ages 13-19 years) psychiatric outpatients with depressive disorders was interviewed for DSM-IV Axis I and Axis II diagnoses. We obtained data by interviewing the adolescents themselves and collecting additional background information from the clinical records. Lifetime age of onset for depression, current episode duration, frequency of suicidal behavior, psychosocial impairment, and the number of current comorbid psychiatric disorders varied between adolescent depressive disorder categories. The type of co-occurring disorder was mainly consistent across depressive disorders. Minor depression and dysthymia (DY) presented as milder depressions, whereas bipolar depression (BPD) and double depression [DD; i.e., DY with superimposed major depressive disorder (MDD)] appeared as especially severe conditions. Only earlier lifetime onset distinguished recurrent MDD from first-episode MDD, and newly emergent MDD appeared to be as impairing as recurrent MDD. Adolescent depressive disorder categories differ in many clinically relevant aspects, with most differences reflecting a continuum of depression severity. Identification of bipolarity and the subgroup with DD seems especially warranted. First episode MDD should be considered as severe a disorder as recurring MDD.     

Risk factors for croup in children with recurrent respiratory infections: a case-control study

Croup accounts for approximately 15% of all lower respiratory disease in children, but little is known about risk factors or its recurrence rate. The aim of this study was to determine the risk factors for croup and recurrent croup and to find out whether it is possible to predict the course of the disease. We considered croup patients who visited the Paediatric Department of Oulu University Hospital as primary health care patients at night during 1996–2000. For most analyses we used sex- and age-matched control patients who had had other respiratory infection but for environmental factors we used population controls. We performed conditional logistic regression analysis on data applying to 182 pairs of patients and controls.
The recurrence rate was high, as 61% of the croup patients had had at least three episodes. Family history of croup was the most significant risk factor for both croup itself and recurrent croup. In multivariable analysis the odds ratio (OR) for the parents having a history of croup was 3.2 (95% CI 1.5, 7.1, P  < 0.01) and 4.1 (95% CI 1.4, 11.7, P  < 0.01) for recurrent croup. Parental smoking appeared to be a risk factor for respiratory infections but not for croup. Patients with croup had a cat as a pet less often than the controls, with OR 0.5 (95% CI 0.2, 1.0, P  = 0.04). Family history appeared to be an exceptionally strong predictive factor for croup and its recurrence. In this patient series prone to respiratory infections recurrence of croup was common.
