Prostate Specific Antigen and Biopsy Contamination in the Göteborg-1 Randomized, Population-Based, Prostate Cancer Screening Trial.

PURPOSE: Even when a screening study has demonstrated a mortality reduction, the degree of pre-testing and contamination is of importance as it can dilute the "true" effect of screening. Our object was to describe the level of pre-testing and contamination in the Göteborg-1 prostate cancer screening trial. MATERIALS AND METHODS: A total of 20,000 men, 50-64 years old, were invited in 1994 and randomized to either a screening group (offered prostate specific antigen testing every 2 years) or to a control group. Follow-up was through December 31, 2014. Outcome measurement was overall testing in the screening group and control group. A positive prostate specific antigen test was defined as a prostate specific antigen ≥3 ng/ml. RESULTS: In the study, 4.2% in the screening group and 4.6% men in the control group were tested before study start. During follow-up, 72% in the control group took at least 1 prostate specific antigen test (contamination) compared to 87% of men in the screening group. Of all prostate specific antigens, 24% in the screening group and 39% in the control group were above threshold. In total, 66% of the men underwent prostate biopsy within 12 months from a raised prostate specific antigen in the screening group and 28% in the control group. CONCLUSIONS: Similar proportions of men were prostate specific antigen-tested in both the screening group and control group, yet only a minority of contamination prostate specific antigens led to biopsy. Also, men in the screening group started screening at a younger age. These could both be explanations for our result that organized screening is more effective in reducing prostate cancer mortality than non-organized testing. When carried out properly and compared to an unscreened population, the effects of organized screening are likely even greater than previously shown in the Göteborg screening trial.

Parity-related variation in cortisol concentrations in hair during pregnancy.

OBJECTIVE: To investigate hair cortisol concentrations (HCC) monthly in pregnant women and to explore the effect of parity. DESIGN: Prospective cohort study from gestational week (GW) 26, at childbirth and postpartum. SETTING: An antenatal care clinic in southeast Sweden. SAMPLE: 390 pregnant women. METHODS: Cortisol was measured using radioimmunoassay in methanol extracts of ground hair samples. MAIN OUTCOME MEASURES: Hair cortisol concentrations. RESULTS: Both primi- and multiparae exhibited an increase in HCC throughout pregnancy. Primiparae had significantly higher HCC in the latter part of the last trimester compared with multiparae (1 month P = 0.003, 2 months P = 0.038). The use of psychotropic medication in the first trimester correlated to HCC postpartum (P < 0.001). HCC in GW 14-17 was associated with HCC in GW 18-21 (primiparae and multiparae, P < 0.001), GW 22-25 (primiparae P = 0.036, multiparae P = 0.033), and 2 months postpartum (primiparae P = 0.049). HCC in GW 18-21 was associated with GW 22-25 in both primiparae (P < 0.001) and multiparae (P < 0.001) as well as 2 months prior to childbirth among primiparae (<0.037). In general, all estimates of HCC in pregnancy and postpartum showed a significant association between HCC for a specific month and the HCC in the previous month (all P < 0.001), except for the association of HCC among primiparae in GW 22-25 and 3 months prior to childbirth. CONCLUSIONS: Increased cortisol concentrations in hair were observed during pregnancy, which decreased 3 months prior to childbirth in multiparae. The results indicate a quicker suppression of the hypothalamic CRH (corticotropin-releasing hormone) production by placenta CRH in multiparous women. TWEETABLE ABSTRACT: Multiparae have a quicker suppression of hypothalamic CRH production by placenta CRH during pregnancy compared to primiparae.

Risk of postnatal depression or suicide after in vitro fertilisation treatment: a nationwide case-control study.

OBJECTIVE: To examine whether women who undergo in vitro fertilisation (IVF) treatment are at greater risk of postnatal suicide or postnatal depression (PND) requiring psychiatric care, compared with women who conceive spontaneously. DESIGN: Case-control study using data from national registers. SETTING: Sweden during the period 2003-2009. POPULATION: Cases were 3532 primiparous women who had given birth following IVF treatment. An aged-matched control group of 8553 mothers was randomly selected from the medical birth register. METHODS: Logistic regression analyses were performed with PND as the outcome, and with known risk factors of PND as well as IVF/spontaneous birth as covariates. MAIN OUTCOME MEASURES: Postnatal depression (PND), defined as diagnoses F32-F39 of the tenth edition of the International Classification of Diseases (ICD-10), within 12 months of childbirth. RESULTS: Initial analyses showed that PND was more common in the control group than in the IVF group (0.8 versus 0.4%; P = 0.04); however, these differences disappeared when confounding factors were controlled for. A history of any psychiatric illness (P = 0.000; odds ratio, OR = 25.5; 95% confidence interval, 95% CI = 11.7-55.5), any previous affective disorder (P = 0.000; OR = 26.0; 95% CI = 10.5-64.0), or specifically a personality disorder (P = 0.028; OR = 3.8; 95% CI = 1.2-12.7) increased the risk of PND. No woman in either group committed suicide during the first year after childbirth. CONCLUSIONS: Whereas mothers who receive IVF treatment are not at increased risk of PND, the risk is increased among mothers with a history of mental illness. TWEETABLE ABSTRACT: A Swedish study on 3532 women showed that IVF treatment does not increase the risk of postnatal depression.

Mental health in women 20-23†years after IVF treatment: a Swedish cross-sectional study.

OBJECTIVE: To assess self-perceived mental health in women treated with in vitro fertilisation (IVF) 20-23 years previously, while comparing them to a reference group, and to determine any differences in mental health between those who had given birth, those who had adopted a child, those who had given birth and adopted a child and those who remained childless. DESIGN: A cross-sectional study. SETTING: A Center of Reproductive Medicine (RMC) at a Swedish University hospital. PARTICIPANTS: 520 women who had undergone at least one IVF cycle at the University Hospital in Linköping between 1986 and 1989. 504 of 520 women (97%) were eligible for follow-up. While 34 women declined, 93 per cent (n=470) of the women agreed to participate. The reference group consisted of 150 women of the Swedish population included in a study that was used to validate the Symptom CheckList (SCL)-90. INTERVENTIONS: Follow-up was conducted in 2008-2009. The SCL-90 was used to measure the women's self-perceived mental health and a questionnaire specific for this study was used to retain demographic information. OUTCOME MEASURES: The SCL-90 assesses 9 primary dimensions; somatisation, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism. There is also a global index of distress. RESULTS: Women who had previously undergone IVF treatment were at increased risk of symptoms of depression (p=0.017), obsessive-compulsion (p=0.02) and somatisation (p≤0.001) when compared to a reference group. In addition, the women who have remained childless are at increased risk of symptoms of depression (p=0.009) and phobic anxiety (p=0.017). CONCLUSIONS: The majority of the women who have been treated with IVF 20-23 years previously appear to be in good mental health. However, women who remain childless and/or without partner after unsuccessful infertility treatment constitute a vulnerable group even later on in life.

Psychiatric illness in women requesting caesarean section.

OBJECTIVE: To compare psychiatric in- and outpatient care during the 5 years before first delivery in primiparae delivered by caesarean section on maternal request with all other primiparae women who had given birth during the same time period. DESIGN: Prospective, population-based register study. SETTING: Sweden. SAMPLE: Women giving birth for the first time between 2002 and 2004 (n = 64 834). METHODS: Women giving birth by caesarean section on maternal request (n = 1009) were compared with all other women giving birth (n = 63 825). The exposure of interest was any psychiatric diagnosis according to the International Statistical Classification of Diseases and Related Health Problems (ninth revision, ICD-9, 290-319; tenth revision, ICD-10, F00-F99) in The Swedish national patient register during the 5 years before first delivery. MAIN OUTCOME MEASURES: Psychiatric diagnoses and delivery data. RESULTS: The burden of psychiatric illnesses was significantly higher in women giving birth by caesarean section on maternal request (10 versus 3.5%, P < 0.001). The most common diagnoses were 'Neurotic disorders, stress-related disorders and somatoform disorders' (5.9%, aOR 3.1, 95% CI 1.1-2.9), and 'Mood disorders' (3.4%, aOR 2.4, 95% CI 1.7-3.6). The adjusted odds ratio for caesarean section on maternal request was 2.5 (95% CI 2.0-3.2) for any psychiatric disorder. Women giving birth by caesarean section on maternal request were older, used tobacco more often, had a lower educational level, higher body mass index, were more often married, unemployed, and their parents were more often born outside of Scandinavia (P < 0.05). CONCLUSIONS: Women giving birth by caesarean section on maternal request more often have a severe psychiatric disease burden. This finding points to the need for psychological support for these women as well as the need to screen and treat psychiatric illness in pregnant women.

Reproduction and mode of delivery in women with vaginismus or localised provoked vestibulodynia: a Swedish register-based study.

OBJECTIVE: To compare sociodemographics, parity and mode of delivery between women diagnosed with vaginismus or localised provoked vestibulodynia (LPV) to women without a diagnosis before first pregnancy. DESIGN: Retrospective, population-based register study. SETTING: Sweden. SAMPLE: All women born in Sweden 1973-83 who gave birth for the first time or remained nulliparous during the years 2001-09. METHODS: Nationally linked registries were used to identify the study population. Women diagnosed with vaginismus or LPV were compared to all other women. Odds ratios for parity and mode of delivery were calculated using multinominal regression analysis and logistic regression. MAIN OUTCOME MEASURES: Parity and mode of delivery. RESULTS: Women with vaginismus/LPV were more likely to be unmarried (P = 0.001), unemployed (P = 0.012), have a higher educational level (P < 0.001), a lower body mass index (P < 0.001) and use nicotine during pregnancy (P = 0.008). They were less likely to give birth (adjusted odds ratio [OR] 0.61, 95% confidence interval [95% CI] 0.56-0.67). Women with vaginismus/LPV more often delivered by caesarean section (P < 0.001) especially for maternal request (adjusted OR 3.48, 95% CI 2.45-4.39). In women having vaginal delivery, those with vaginismus/LPV were more likely to suffer a perineal laceration (adjusted OR 1.87, 95% CI 1.56-2.25). CONCLUSIONS: Women with vaginismus/LPV are less likely to give birth and those that do are more likely to deliver by caesarean section and have a caesarean section based upon maternal request. Those women delivering vaginally are more likely to suffer perineal laceration. These findings point to the importance of not only addressing sexual function in women with vaginismus/LPV but reproductive function as well.

Risk for congenital malformations in offspring of women who have undergone bariatric surgery. A national cohort.

OBJECTIVE: To study the risk for congenital anomalies in the first child of women after bariatric surgery compared with all other women giving birth to their first child and divided by maternal body mass index (BMI) groups. DESIGN: Prospective, population-based register study. SETTING: Sweden. SAMPLE: All firstborn children to women born 1973-83 were studied to determine if they had a congenital anomaly and a mother who had undergone bariatric surgery before pregnancy. METHODS: A total of 270,805 firstborns; of which 341 had mothers who had had bariatric surgery before delivery. We retrieved information on the women's marital or cohabitation status, smoking, BMI, diabetes and hypertension during pregnancy. MAIN OUTCOME MEASURES: Congenital malformations. RESULTS: Of the firstborn children to mothers who had had bariatric surgery before pregnancy, 4.1% (95% confidence interval [95% CI] 2.2-6.0) were malformed compared with 3.4% (95% CI 3.3-3.5) of those whose mothers had not undergone bariatric surgery. The risk for congenital malformation in firstborn children increased with increasing maternal BMI. The adjusted odds ratio (OR) for congenital malformation among children whose mothers' BMI ranged between 25 and 29 kg/m(2) was 1.09 (95% CI 1.03-1.15), whose mothers' BMI ranged between 30 and 34 kg/m(2) was 1.14 (1.05-1.24) and whose mothers' BMI was ≥35 kg/m(2) was 1.30 (95% CI 1.16-1.45) compared with those whose mothers had a normal BMI. Bariatric surgery before pregnancy did not have any effect on the odds ratio for having congenital malformation (OR = 1.09, 95% CI 0.63-1.91). CONCLUSIONS: Preconception bariatric surgery does not seem to affect the risk for congenital malformations but a high to very high BMI does appear to increase the risk.

Safety and immunogenicity of a glycoprotein D genital herpes vaccine in healthy girls 10-17 years of age: results from a randomised, controlled, double-blind trial.

OBJECTIVE: The investigational AS04-adjuvanted herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2) subunit prophylactic vaccine ('HSV vaccine'; GlaxoSmithKline Vaccines) has been shown to be well tolerated in adults, but limited data exist for pre-teen and adolescent girls, a likely target population. The primary objective of this study was to compare the occurrence of serious adverse events (SAEs) over 12 months between HSV vaccine recipients and saline recipients (placebo control group) in pre-teen and adolescent girls. The immunogenicity of the HSV vaccine was also assessed. METHODS: Healthy girls aged 10-17 years, stratified by age (10-15 years; 16-17 years), were randomised 2:1:1 to receive the HSV vaccine, a hepatitis A vaccine (Havrix™; HAV control) or placebo (saline) according to a 0-, 1-, 6-month schedule. Participants and study personnel not involved in the preparation or administration of vaccines were blinded to treatment. Safety and immunogenicity analyses were performed overall and by age (10-15 years; 16-17 years) and HSV serostatus. RESULTS: No statistically significant difference in the percentage of subjects with SAEs was observed between the HSV and saline group, or between the HSV and pooled control (HAV and saline) groups. The HSV vaccine was well tolerated, although a higher incidence of solicited local symptoms was observed in the HSV group than in the control group. Neither age nor HSV serostatus at the time of study entry had an impact on the safety profile of this vaccine. The HSV vaccine was immunogenic regardless of pre-vaccination HSV serostatus. Higher anti-gD geometric mean concentrations were observed in HSV-1 seropositive participants than in HSV-1 seronegative participants. CONCLUSION: The HSV vaccine had an acceptable safety profile, and was well tolerated and immunogenic when administered to girls aged 10-17 years regardless of age or HSV pre-vaccination serostatus.

Premature birth and low birthweight are associated with a lower rate of reproduction in adulthood: a Swedish population-based registry study.

BACKGROUND: The aim of this study was to investigate if individuals born with sub-optimal birth characteristics have reduced probability of reproducing in adulthood. METHODS: Using population-based registries, the authors included 522 216 males and 494 692 females born between 1973 and 1983 and examined their reproductive status as of 2006. Outcome measure was the hazard ratio (HR) of reproducing. Adjustments were made for socio-economic factors. RESULTS: Males and females born very premature displayed a reduced probability of reproducing [HR = 0.78, 95% confidence interval (CI): 0.70-0.86 for males; HR = 0.81, CI: 0.75-0.88 for females]. Likewise for very low birthweight (HR = 0.83, CI: 0.71-0.95 for males; HR = 0.80, 95% CI: 0.72-0.89 for females). Individuals born large for gestational age (LGA) displayed no significant changes. Males born small for gestational age (SGA) had a 9% lower reproductive rate (CI: 0.89-0.94) and that reduction increased as the individuals aged. Women born SGA tended to start reproducing at an earlier age. CONCLUSION: The results suggest that being born with low birthweight, premature or SGA (for males) is associated with a reduced probability of reproducing as an adult. LGA shows no statistically significant relationship with future reproduction.

Total cost comparison of standard antenatal care with a weight gain restriction programme for obese pregnant women.

OBJECTIVE: To perform a cost comparison of a weight gain restriction programme for obese pregnant women with standard antenatal care, and to identify if there were differences in healthcare costs within the intervention group related to degree of gestational weight gain or degree of obesity at programme entry. STUDY DESIGN: A comparison of mean healthcare costs for participants of an intervention study at antenatal care clinics with controls in south-east Sweden. METHODS: In total, 155 women in an intervention group attempted to restrict their gestational weight gain to <7 kg. The control group comprised 193 women. Mean costs during pregnancy, delivery and the neonatal period were compared with the costs of standard care. Costs were converted from Swedish Kronor to Euros (€). RESULTS: Healthcare costs during pregnancy were lower in the intervention group. There was no significant difference in total healthcare costs (i.e. sum of costs during pregnancy, delivery and the neonatal period) between the intervention group and the control group. Within the intervention group, the subgroup that gained 4.5-9.5 kg had the lowest costs. The total cost, including intervention costs, was € 1283 more per woman/infant in the intervention group compared with the control group (P=0.025). The degree of obesity at programme entry had no bearing on the outcome. CONCLUSIONS: The weight gain restriction programme for obese pregnant women was effective in restricting gestational weight gain to <7 kg, but had a higher total cost compared with standard antenatal care.

Attitudes towards mode of birth among Swedish midwives.

OBJECTIVE: to investigate midwives' attitudes and opinions on mode of birth. DESIGN: exploratory descriptive study. Data were collected via study-specific questionnaires during 2006. SETTING: southeastern Sweden. PARTICIPANTS: all midwives working in two counties. FINDINGS: regardless of age, experience and working field, the midwives considered a reasonable caesarean rate to be around 11.5 per cent. None of the participants thought that the caesarean rate was too low. Midwives younger than 50 years tended to consider the current caesarean rate to be too high (p=0.059). Midwives working on labour wards stated that they thought the current caesarean rate was too high compared with midwives working at antenatal care clinics (ACCs) (p<0.001). Midwives working at ACCs agreed with the statements 'one should agree to a woman's right to have an elective caesarean' (p<0.001) and 'elective caesarean is the best choice for a woman with fear of birth' (p=0.046) more often than midwives working on labour wards, regardless of age or working experience. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: midwives working at ACCs are more willing to accept caesarean section at the woman's request and for women with fear of birth. It is of importance that ACC caregivers and professionals on labour wards increase their collaboration and have continuous discussions with one another in an attempt to reach consensus about the appropriate caesarean rates on evidence-based grounds.

Hospitalization in adolescence affects the likelihood of giving birth: a Swedish population-based register study.

AIM: To examine the effect of hospitalization during adolescence on the likelihood of giving birth. METHODS: 142 998 women born in 1973-75 were followed with the help of the Swedish Medical Birth Register (MBR) and the Swedish Total Population Register (TPR) up until the end of 2000 with respect to their likelihood of giving birth. All analyses were adjusted for parental socio-economic characteristics and factors related to the studied women's own birth. RESULTS: The likelihood of giving birth between 20 and 27 years of age was positively affected by hospitalization at least once during adolescence according to the Swedish Hospital Discharge Register (HDR); adjusted hazard ratio (HR) = 1.32, 95% confidence interval: 1.29-1.35. Women hospitalized due to genitourinary diseases, respiratory diseases, abdominal problems and abuse of alcohol and drugs were more likely to have given birth during the study period, while hospitalizations according to cerebral palsy and congenital malformations tended to decrease childbearing. Women hospitalized due to psychiatric diseases had an increase likelihood of given birth at 20-24 years but a reduced thereafter. CONCLUSION: A majority of the causes of hospitalization during adolescence increased the likelihood of giving birth between ages 20 to 27.

Preterm birth or foetal growth impairment and psychiatric hospitalization in adolescence and early adulthood in a Swedish population-based birth cohort.

OBJECTIVE: Preterm birth and restricted foetal growth are related to symptoms of psychiatric disorder. Our aim was therefore to investigate possible relations between being born preterm and/or small for gestational age (SGA) and later psychiatric hospitalization. METHOD: A population-based registry study of psychiatric hospitalization of in total 155,994 boys and 148,281 girls born in Sweden in 1973-1975. RESULTS: The risk of hospitalization for all mental disorders was increased for preterm SGA boys (OR 2.19, 95% CI 1.49-3.21); at-term SGA boys (OR 1.55, 95% CI 1.34-1.79); at-term SGA girls (OR 1.31, 95% CI 1.15-1.50). At-term SGA boys and girls suffered increased risk of anxiety and adjustment disorders (OR 1.70, 95% CI 1.18-2.45 and OR 1.49, 95% CI 1.14-1.94). Preterm SGA boys were at risk of personality disorders (OR 3.30, 95% CI 1.16-9.41) and psychotic disorders (OR 4.36, 95% CI 1.85-10.30). CONCLUSION: The results show a relationship between being born SGA and later psychiatric hospitalization, where preterm birth and male gender seem to increase the risk.

Weight gain restriction for obese pregnant women: a case-control intervention study.

OBJECTIVE: To minimise obese women's total weight gain during pregnancy to less than 7 kg and to investigate the delivery and neonatal outcome. DESIGN: A prospective case-control intervention study. SETTING: Antenatal care clinics in the southeast region of Sweden. POPULATION: One hundred fifty-five pregnant women in an index group and one hundred ninety-three women in a control group. METHODS: An intervention programme with weekly motivational talks and aqua aerobic classes for obese pregnant women. MAIN OUTCOME MEASURES: Weight gain in kilograms, delivery and neonatal outcome. RESULTS: The index group had a significantly lower weight gain during pregnancy compared with the control group (P < 0.001). The women in the index group weighed less at the postnatal check-up compared with the weight registered in early pregnancy (P < 0.001). The percentage of women in the index group who gained less than 7 kg was greater than that of women in the control group who gained less than 7 kg (P= 0.003). The percentage of nulliparous women in this group was greater than that in the control group (P= 0.018). In addition, the women in the index group had a significantly lower body mass index at the postnatal check-up, compared with the control group (P < 0.001). There were no differences between the index group and the control group regarding birthweight, gestational age and mode of delivery. CONCLUSION: The intervention programme was effective in controlling weight gain during pregnancy and did not affect delivery or neonatal outcome.

A follow-up study of postpartum depressed women: recurrent maternal depressive symptoms and child behavior after four years.

OBJECTIVE: To investigate the prevalence of depressive symptoms and self reported health of women who have shown previous postpartum depressive symptoms. To examine the behavior of four-year-old children born to mothers affected by postpartum depression. METHODS: Longitudinal study. The index group (n = 251) constituted of all women with postpartum depressive symptoms on the Edinburgh Postnatal Depression Scale (EPDS), in a population-based study made in the late 1990s. The control group (n = 502) consisted of women without postpartum depressive symptoms on the EPDS at the same occasion. Approximately four years after delivery these women were asked to answer a short questionnaire on general health, the EPDS, and also to assess their child's behavior with the Richman Pre-School Behaviour Checklist. RESULTS: Women with a history of postpartum depressive symptoms were approximately 6 times more likely to have recurrent depressive symptoms (OR = 5.82, 95% CI: 3.79-8.93), compared to those without postpartum depressive symptoms, and they were also more likely to experience physical and mental illness. Although postpartum depressive symptoms in the mothers were involved in explaining the likelihood of behavioral problems in their four-year-old children, mothers with current depressive symptoms were the most likely to have a child with behavioral problems (OR = 4.71, 95% CI: 1.88-11.78). CONCLUSION: Postpartum depressive illness constitutes a risk for future illness as well as maternal perceived behavioral problems in offspring. In order to diminish long-term adverse consequences for the mother and the child there is a great need to recognize and treat women with postpartum depressive symptoms as early as possible.

Influence of obesity on the use of sickness absence and social benefits among pregnant working women.

OBJECTIVE: To evaluate if obesity in early pregnancy has any possible impact on the capacity of pregnant women to engage in gainful employment. METHODS: Register data from a database on sickness absence and pregnancy benefit and parental benefit claims were combined with type of occupation and body mass index (BMI) for 693 women consecutively delivered during the course of one year at a county hospital in Sweden. RESULTS: The results showed the lowest BMI among women who had administrative jobs and the highest BMI in women who undertook more burdensome and heavy types of manual work. A significant increase in BMI was also seen among those pregnant women who were registered as unemployed. The finding that in the manual types of occupation, obese pregnant women took almost twice as many days of leave provided by the parental benefit programme as did women with a BMI of <25, indicates that obese pregnant women perhaps do not have the same physical endurance required to manage the combined demands of work and pregnancy. No differences were found with regard to sickness absence between obese women and pregnant women with normal BMI; however, differences were found between different occupational groups. CONCLUSIONS: Our study indicates that a woman's BMI at the beginning of pregnancy is associated with her occupational status. Obesity among pregnant women may well be used as a psychosocial indicator as obesity correlates with social and economic problems. Any planned weight reduction programme in antenatal care must therefore consider this important psychosocial aspect.

Temperament and character in women with postpartum depression.

OBJECTIVE: To investigate whether women with postpartum depression differ in personality traits from healthy postpartum women, healthy controls from the normal Swedish population and non-postpartum women with major depression. METHODS: Forty-five women with postpartum depression were compared with 62 healthy postpartum women, 62 age-matched, healthy, non-postpartum women from a normal sample and 74 non-postpartum women with major depression from a clinical sample. The edinburgh postnatal depression scale was used in order to screen for postpartum depression. A clinical diagnostic interview was done including a rating with the Montgomery-Asberg depression rating scale. Personality i.e. temperament and character was measured by the temperament and character inventory. RESULTS: Harm avoidance (HA) was higher (p < 0.001) and self-directedness (SD) scored lower (p < 0.001) in women with postpartum depression compared to healthy postpartum women. These differences were the most important differences between these two groups. Women with postpartum depression scored lower (p = 0.001) in cooperativeness (CO) and higher (p = 0.019) in self-transcendence (ST) compared to healthy postpartum women. Women with postpartum depression scored overall similar to women with major depression. CONCLUSION: High HA and low SD can be seen as vulnerability factors for developing a depression and especially in a stressful situation as childbirth.

HLA class II alleles associated with infection by HPV16 in cervical cancer in situ.

HLA class II alleles have been associated with an increased risk of developing cervical cancer through infection with oncogenic forms of human papilloma virus (HPV). We have examined the association of variation at the DRB1 and DQB1 loci with HPV16 infection and risk of development of cervical cancer by analysis of 440 cases diagnosed with cervical cancer in situ and 476 age-matched controls in a retrospective case-control study. The infection history of a woman was studied by analysis of cervical smears taken at multiple times during a period of up to 27 years (1969-95). The frequency of a number of alleles are either increased (DRB1*0801, DRB1*1501, DQB1*0402 and DQB1*0602) or decreased (DRB1*0101, DRB1*1301, DQB1*0501 and DQB1*0603) in the cancer patients compared to the controls. After correction for multiple testing, only the DQB1*0602 and the DRB1*1501 alleles remain associated with cancer and only in HPV16-infected patients (DQB1*0602: 102/264 (39%) vs. 130/476 (28%), p = 0.028 and DRB1*1501: 104/259 (40%) vs. 132/469 (28%), p = 0.027). These alleles are associated primarily with infection by HPV and only indirectly affect the risk of developing cervical cancer in situ. To study the impact of these alleles on persistence of infection, women with short-term infections were compared to those with long-term infections. Carriers of DQB1*0602 and DRB1*1501 were more frequent in the group with long-term HPV infections, indicating that these class II alleles contribute to the inability to clear an HPV infection.

Prevalence of depressive symptoms in late pregnancy and postpartum.

BACKGROUND: Postnatal depression refers to a non-psychotic depressive episode that begins in or extends into the postpartum period. The aims of this study were to examine the prevalence of depressive symptoms in a pregnant and later postnatal population, to determine the natural course of these symptoms and whether there is an association between antenatal and postnatal depressive symptomatology. METHODS: A longitudinal study with a total population of 1,558 consecutively registered pregnant women in the southeast region of Sweden. Presence of depressive symptoms was measured with the Edinburgh Postnatal Depression Scale on four occasions namely in gestational week 35-36, in the maternity ward, 6-8 weeks and 6 months postpartum. RESULTS: The prevalence of depressive symptoms during late pregnancy was 17%; in the maternity ward 18%; 6-8 weeks postnatally 13%; and 6 months postnatally, 13%. A correlation between antenatal and postnatal depressive symptoms was found (r=0.50, p<0.0001). CONCLUSION: Detection of women at risk for developing postnatal depressive symptoms can be done during late pregnancy. Antenatal care clinics constitute a natural and useful environment for recognition of women with depressive symptoms.

A prospective study showing long-term infection with human papillomavirus 16 before the development of cervical carcinoma in situ.

Human papillomavirus 16 (HPV16) is a predominant cause of cervical neoplasia. However, no population-based study with long-term follow-up has clarified the temporal relationship between HPV16 infection and occurrence of carcinoma in situ, or the importance of recurrent or persistent infection. This nested case-control study was carried out in a population-based cohort of women participating in cytological screening whose initial smear, taken in 1969-1995, was normal. During up to 26 years of follow-up, carcinoma in situ was diagnosed in 484 eligible women. Archival smears from these women were compared with smears from 619 individually matched controls. After DNA extraction, a highly sensitive PCR system was used to detect HPV16. Among case women, the prevalence of HPV16 positivity was 56% at the time of diagnosis. The relative risk of cervical carcinoma in situ increased from 3.6 (95% confidence interval, 1.2-11.0) 13 years before diagnosis to 11.1 (95% confidence interval, 5.5-22.2) 1 year before diagnosis. Having a positive smear at entry to the cohort increased risk >5-fold, whereas having persistent infection with HPV in two subsequent smears increased risk 30-fold. We estimated that among HPV16-positive women, the median incubation period from infection to carcinoma in situ was 7-12 years. We conclude that evidence of persistent and/or recurrent infection is associated with a drastically higher risk of cervical carcinoma in situ than occasional infection with HPV16.
