- Context: Congenital adrenal hyperplasia (CAH), CYP21A2 deficiency, results in cortisol and aldosterone deficiency and increased production of androgens, with a good genotype phenotype correlation. Objective: To study psychosocial outcomes in relation to clinical severity, CYP21A2 genotype, in men and women. Design: An epidemiological study with a matched cohort control design. Setting: All known CAH patients in Sweden. Participants: 588 patients, >95% with known severity of CAH; 100 controls per patient matched for sex, year and place of birth. Main outcome and measures: Proxies for quality of life were selected: level of education, employment, income, sick-leave, disability pension, marriage and children. Results: Women with salt-wasting (SW) CAH had completed primary education less often (OR 0.3), not explained by neonatal salt-crisis or hypoglycemia since the men did not differ from controls. Men and women in the less severe I172N genotype group were more likely to have an academic education (OR 1.8) SW women were more likely to have an income in the top 20 percentile (OR 2.0 ). Both men and women had more disability pension (OR 1.5) and sick leave (OR 1.7). The men more often had long lasting employment (OR 3.1). Men were more often (OR 1.6) while women were less often married (OR 0.7). Patients had children less often (OR 0.3). Conclusions: This study shows important outcome differences regarding education, employment, marriage and fertility depending on sex and severity of CAH. The mechanisms behind this and the increased risk for sick leave or disability pension in both men and women should be identified to improve medical and psychological care.

Hypospadias and increased risk for neurodevelopmental disorders
- 2014
-
In: Journal of Child Psychology and Psychiatry. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 0021-9630 .- 1469-7610.

Journal article (peer-reviewed)abstract
- BACKGROUND: Hypospadias (aberrant opening of the urethra on the underside of the penis) occurs in 1 per 300 newborn boys. It has been previously unknown whether this common malformation is associated with increased psychiatric morbidity later in life. Studies of individuals with hypospadias also provide an opportunity to examine whether difference in androgen signaling is related to neurodevelopmental disorders. To elucidate the mechanisms behind a possible association, we also studied psychiatric outcomes among brothers of the hypospadias patients. METHODS: Registry study within a national cohort of all 9,262 males with hypospadias and their 4,936 healthy brothers born in Sweden between 1973 and 2009. Patients with hypospadias and their brothers were matched with controls by year of birth and county. The following outcomes were evaluated (1) any psychiatric (2) psychotic, (3) mood, (4) anxiety, (5) eating, and (6) personality disorders, (7) substance misuse, (8) attention-deficit hyperactivity disorder (ADHD), (9) autism spectrum disorders (ASD), (10) intellectual disability, and (11) other behavioral/emotional disorders with onset in childhood. RESULTS: Patients with hypospadias were more likely to be diagnosed with intellectual disability (OR 3.2; 95% CI 2.8-3.8), ASD (1.4; 1.2-1.7), ADHD (1.5; 1.3-1.9), and behavioral/emotional disorders (1.4; 1.2-1.6) compared with the controls. Brothers of patients with hypospadias had an increased risk of ASD (1.6; 1.3-2.1) and other behavioral/emotional disorders with onset in childhood (1.2; 0.9-1.5) in comparison to siblings of healthy individuals. A slightly higher, although not statistically significant, risk was found for intellectual disability (1.3; 1.0-1.9). No relation between other psychiatric diagnosis and hypospadias was found. CONCLUSIONS: This is the first study to identify an increased risk for neurodevelopmental disorders in patients with hypospadias, as well as an increased risk for ASD in their brothers, suggesting a common familial (genetic and/or environmental) liability.

Deficient cardiovascular stress reactivity predicts poor executive functions in adults with attention-deficit/hyperactivity disorder
- 2011
-
In: Journal of Clinical and Experimental Neuropsychology. - : Informa UK Limited. - 1380-3395 .- 1744-411X. ; 33:1, s. 63-73
-
Journal article (peer-reviewed)abstract
- Associations between cardiovascular stress markers, subjective stress reactivity, and executive functions were studied in 60 adults (30 with attention-deficit/hyperactivity disorder, ADHD, and 30 controls) using the Paced Auditory Serial Addition Test (PASAT, a test of executive functions) as a cognitive stressor. Despite higher self-perceived stress, the adults with ADHD showed lower or atypical cardiovascular stress reactivity, which was associated with poorer performance on PASAT. Using cardiovascular stress markers, subjective stress, and results on PASAT as predictors in a logistic regression, 83.3% of the ADHD group and 86.9% of the controls could be classified correctly.

Journal article (peer-reviewed)abstract
- Attention-deficit/hyperactivity disorder (ADHD) in adults is associated with significant impairment in many life activities and may thus increase the risk of chronic stress in everyday life. We compared adults with a DSM-IV ADHD diagnosis (n=28) with healthy controls (n=28) regarding subjective stress and amounts of stressors in everyday life, diurnal salivary cortisol in the everyday environment and salivary cortisol before and after cognitive stress in a laboratory setting. The association between cortisol concentrations and impulsivity was also investigated. Consistent with assumptions, individuals with ADHD reported significantly more self-perceived stress than controls, and subjective stress correlated with the amount of stressors in everyday life. The two groups were comparable with respect to overall diurnal cortisol levels and rhythm, as well as in pre- and post-stress cortisol concentrations. Post-stress cortisol (but not baseline cortisol) concentration was positively correlated with impulsivity. The group with high post-stress cortisol also reported more symptoms of depression and anxiety, as well as self-perceived stress and stressors in everyday life. The diagnosis of ADHD significantly increased the risk of belonging to the group with high post-stress cortisol levels. The results in this study warrant a focus not only on the primary diagnosis of ADHD, but also calls for a broader assessment of stressors and subjective stress in everyday life, as well as support comprising stress management and coping skills.

Prenatal Dexametasone treatment of children at risk for congenital adrenal hyperplasia affects cognitive functions.
- 2007
-
In: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. ; 92
-
Journal article (peer-reviewed)abstract
- In Sweden, during 1985-1995, 40 foetuses at risk for congenital adrenal hyperplasia (CAH) were treated with dexamethasone (DEX) in order to prevent virilisation of affected females. We report long-term effects on neuropsychological functions and scholastic performance of this controversial treatment.Prenatally treated children, 7-17 years, were assessed with standardized neuropsychological tests (NEPSY and WISC-III) and child-completed questionnaires measuring self-perceived scholastic competence (SPPC). A parent-completed questionnaire (CBCL/4-18 School Scale) was used to evaluate whether the treatment had any impact on the children’s school performance.Of 40 DEX treated children, 26 (median age 11 years) participated in the study. Thirty-five sex- and age matched healthy children were controls. There were no between-group differences concerning psychometric intelligence, measures of cerebral lateralization, memory encoding, and long term memory. Short term treated, CAH unaffected children performed worse than the control group on a test assessing verbal working memory (p=0.003), and on self-perception of scholastic competence (p=0.003). Prenatally treated, CAH affected children performed poorer than controls on tests measuring verbal processing speed, although this difference disappeared when controlling for the child’s Full-Scale IQ (FSIQ).This study indicates that prenatal DEX treatment is associated with previously not described long-term effects on verbal working memory and certain aspects of self-perception that could be related to poorer verbal working memory. These findings may thus question future DEX treatment of congenital adrenal hyperplasia. Therefore, we encourage additional retrospective studies of larger cohorts to either confirm or challenge the present findings.

Health-Related Quality of Life After Surgery for Small Intestinal Neuroendocrine Tumours
- 2018
-
In: World Journal of Surgery. - : Springer Science and Business Media LLC. - 0364-2313 .- 1432-2323. ; 42:10, s. 3231-3239
-
Journal article (peer-reviewed)abstract
- Background: Overall survival for patients with small intestinal neuroendocrine tumours (siNETs) is long, even with metastatic disease, making quality of life issues relevant. The impact of surgery on quality of life is not known. We investigated determinants of health-related quality of life in patients who had undergone surgery for a siNET. Methods: Patients operated for a siNET between 1998 and 2016 at Skåne University Hospital (Lund, Sweden), who were alive in February 2017, were sent two questionnaires constructed by the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30, EORTC QLQ-GINET21). Global quality of life, physical function, disease-related worries, diarrhoea and endocrine symptoms were evaluated with linear and logistic regression in relation to patient-, tumour- and treatment-related factors. Statistical analysis was performed using STATA 11®. Results: One hundred patients (84%) completed the questionnaires. Women had worse global quality of life (p = 0.019), more disease-related worries (p < 0.001) and endocrine symptoms (p = 0.017) than men. Older age was associated with more disease-related worries (p = 0.007), but fewer endocrine symptoms (p = 0.034). Non-symptomatic tumour versus symptomatic tumour (p = 0.002), and treatment with somatostatin analogues versus no treatment (p = 0.040) were associated with less diarrhoea. Small versus large bowel resection was associated with better global quality of life (p = 0.036) and physical function (p = 0.035). Conclusions: Male gender, younger age, treatment with somatostatin analogues, non-symptomatic tumour, and small intestinal surgery rather than large bowel surgery were associated with better quality of life.

Hypospadias as a novel feature in spinal bulbar muscle atrophy
- 2016
-
In: Journal of Neurology. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 0340-5354 .- 1432-1459.
-
Journal article (peer-reviewed)abstract
- Spinal and bulbar muscle atrophy (SBMA) is an X-linked neuromuscular disorder caused by CAG repeat expansions in the androgen receptor (AR) gene. The SBMA phenotype consists of slowly progressive neuromuscular symptoms and undermasculinization features as the result of malfunction of the AR. The latter mainly includes gynecomastia and infertility. Hypospadias is also a feature of undermasculinization with an underdeveloped urethra and penis; it has not been described as part of the SBMA phenotype but has been suggested to be associated with a prolonged CAG repeat in the AR gene. This study includes the first epidemiologic description of the co-occurrence of hypospadias and SBMA in subjects and their male relatives in Swedish population-based health registers, as well as an additional clinical case. One boy with severe hypospadias was screened for mutations in the AR gene and was found to have 42 CAG repeats in it, which is in the full range of mutations causing SBMA later in life. We also detected a maximum of four cases displaying the combination of SBMA and hypospadias in our national register databases. This is the third case report with hypospadias in association with CAG repeat expansions in the AR gene in the full range known to cause SBMA later in life. Our findings suggest that hypospadias may be an under diagnosed feature of the SBMA phenotype and we propose that neurologists working with SBMA further investigate and report the true prevalence of hypospadias among patients with SBMA.

Journal article (peer-reviewed)abstract
- PITX3 is a transcription factor of importance for the differentiation and survival of midbrain dopaminergic neurons, the gene of which is disrupted in a putative mouse model for Parkinson's disease (PD). The A-allele of a HapMap tagging SNP (rs4919621) that was genotyped in a population of 361 PD patients, 69 of which had early onset, and in 333 controls, was significantly more common in PD patients with an early age of onset when compared either to controls (p=0.002) or to PD patients with late onset (p=0.001). In contrast, a previous finding suggesting a SNP (rs3758549) in the putative promoter region of the PITX3 gene to be associated with PD could not be replicated.

Addison's Disease in Women Is a Risk Factor for an Adverse Pregnancy Outcome
- 2010
-
In: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 95:12, s. 5249-5257

Journal article (peer-reviewed)abstract
- Context: Autoimmune Addison's disease(AAD) tends to affect young and middle-aged women. It is not known whether the existence of undiagnosed or diagnosed AAD influences the outcome of pregnancy. Objective: The aim of the study was to compare the number of children and pregnancy outcomes in individuals with AAD and controls. Design and Setting: We conducted a population-based historical cohort study in Sweden. Patients: Through the Swedish National Patient Register and the Total Population Register, we identified 1,188 women with AAD and 11,879 age-matched controls who delivered infants between 1973 and 2006. Main Outcome Measures: We measured parity and pregnancy outcome. Results: Adjusted odds ratios (ORs) for infants born to mothers with deliveries 3 yr or less before the diagnosis of AAD were 2.40 [95% confidence interval (Cl), 1.27-4.53] for preterm birth (<= 37 wk), 3.50 (95% Cl, 1.83-6.67) for low birth weight (<2500 g), and 1.74 (95% Cl, 1.02-2.96) for cesarean section. Compared to controls, women who gave birth after their AAD diagnosis were at increased risk of both cesarean delivery (adjusted OR, 2.35; 95% Cl, 1.68-3.27) and preterm delivery (adjusted OR, 2.61; 95% Cl, 1.69-4.05). Stratifying by isolated AAD and concomitant type 1 diabetes and/or autoimmune thyroid disease in the mother did not essentially influence these risks. There were no differences in risks of congenital malformations or infant death. Women with AAD had a reduced overall parity compared to controls (P < 0.001). Conclusion: Clinically undiagnosed and diagnosed AAD both entail increased risks of unfavorable pregnancy outcomes. AAD also influences the number of childbirths.

High Surface Area "3D Graphene Oxide" for Enhanced Sorption of Radionuclides
- 2022
-
In: Advanced Materials Interfaces. - : John Wiley & Sons. - 2196-7350. ; 9:18
-
Journal article (peer-reviewed)abstract
- Here preparation of high surface area activated reduced graphene oxide (arGO) oxidized into a 3D analogue of defect-rich GO (dGO) is reported. Surface oxidation of arGO results in carbon to oxygen ratio C/O = 3.3, similar to the oxidation state of graphene oxide while preserving high BET surface area of about 880 m2 g−1. Analysis of surface oxidized arGO shows high abundance of oxygen functional groups which converts hydrophobic precursor into hydrophilic material. High surface area carbons provide the whole surface for oxidation without the need of intercalation and lattice expansion. Therefore, surface oxidation methods are sufficient to convert the materials into 3D architectures with chemical properties similar to graphene oxide. The "3D graphene oxide" shows high sorption capacity for U(VI) removal in an extraordinary broad interval of pH. Notably, the surface oxidized carbon material has a rigid 3D structure with micropores accessible for penetration of radionuclide ions. Therefore, the bulk "3D GO" can be used as a sorbent directly without dispersing, the step required for GO to make its surface area accessible for pollutants.

Congenital adrenal hyperplasia and risk for psychiatric disorders in girls and women born between 1915 and 2010: A total population study.
- 2015
-
In: Psychoneuroendocrinology. - : Elsevier BV. - 1873-3360 .- 0306-4530. ; 60, s. 195-205
-
Journal article (peer-reviewed)abstract
- Congenital adrenal hyperplasia (CAH) is a chronic condition and individuals are exposed to elevated androgen levels in utero as a result of the endogenous cortisol deficiency. Prenatal androgen exposure has been suggested to influence mental health, but population based studies on psychiatric morbidity among girls and women with CAH are lacking. Therefore, we performed a cohort study based on Swedish nationwide registers linked with the national CAH register. Girls and women with CAH due to 21-hydroxylase deficiency (n=335) born between January 1915 and January 2010 were compared with aged-matched female (n=33500) and male controls (n=33500). Analyses were stratified by phenotype [salt wasting (SW), simple virilizing (SV), and non-classical type (NC)] and by CYP21A2 genotype subgroups (null, I2splice, I172N, and P30L). Results are presented as estimated risks (OR, 95%CI) of psychiatric disorders among girls and women with CAH compared with age-matched controls. Any psychiatric diagnoses were more common in CAH females compared with female and male population controls [1.9 (1.4-2.5), and 2.2 (1.7-2.9)]. In particular, the risk of alcohol misuse was increased compared with female and male population controls [2.8 (1.7-4.7) and 2.1 (1.2-3.5)], and appeared most common among the girls and women with the most severe null genotype [6.7 (2.6-17.8)]. The risk of stress and adjustment disorders was doubled compared with female population controls [2.1 (1.3-3.6)]. Girls and women with CAH have an increased risk of psychiatric disorders in general and substance use disorders in particular compared with unexposed females, with the highest risk among those with the most severe genotype. Prenatal androgen exposure and deficient endogenous cortisol and/or adrenaline production may provide explanations for these findings, but other factors related to CAH cannot be excluded.

-
Journal article (peer-reviewed)abstract
- PURPOSE To present long-term ocular complications and electroretinographic (ERG) findings in children with long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency - a life-threatening metabolic disease - and the relation to age at diagnosis, treatment and other clinical parameters. METHODS Ten children with LCHAD deficiency underwent repeated ophthalmological evaluations including ERG. RESULTS All 10 children developed chorioretinal pathology. Regardless of age at diagnosis, initiation of treatment and age at examination, inter-individual differences were present. Profound chorioretinal atrophy, severe visual impairment and progressive myopia had developed in two teenagers. Milder chorioretinopathy with or without subnormal visual acuity was present in all other children. ERG was pathological in seven children. The chorioretinopathy often started in the peripapillary or perimacular areas. In one patient, unilateral visual impairment was associated with fibrosis. CONCLUSION Early diagnosis and adequate therapy might delay but not prevent the progression of retinal complications. Late diagnosis with severe symptoms at diagnosis, neonatal hypoglycaemia and frequent decompensations may increase the progression rate of the chorioretinopathy. LCHAD deficiency, a potentially lethal disease, is sometimes difficult to diagnose. Unusual chorioretinal findings should alert the ophthalmologist to the long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, especially if there is a history of neonatal hypoglycaemia or failure to thrive.

Increased cardiovascular and metabolic morbidity in patients with 21-hydroxylase deficiency : a Swedish population-based national cohort study
- 2015
-
In: The Journal of Clinical Endocrinology & Metabolism. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 0021-972X. ; 100:9, s. 3520-3528
-
Journal article (peer-reviewed)abstract
- CONTEXT: Congenital adrenal hyperplasia (CAH) is lethal in its most severe forms if not treated with glucocorticoids. However, glucocorticoids may increase the risk of cardiovascular and metabolic morbidity. OBJECTIVE: This study aimed to study cardiovascular and metabolic morbidity in CAH. DESIGN, SETTING, AND PARTICIPANTS: Patients with CAH due to 21-hydroxylase deficiency (n = 588; >80% with known CYP21A2 mutations) were compared with controls matched for sex, year, and place of birth (n = 58 800). Data were obtained by linking national population-based registers. Subgroup analyses were performed regarding sex, clinical severity (salt wasting, simple virilizing, nonclassic), CYP21A2 genotype (null, I2 splice, I172N, P30L), and stratified by the introduction of neonatal screening, age groups, and nonobesity. MAIN OUTCOME MEASURES: To study cardiovascular and metabolic morbidity in CAH. RESULTS: In CAH, both any cardiovascular and metabolic disorders (OR [odds ratio], 3.9; 95% CI [confidence interval], 3.1-5.0), and cardiovascular disease (OR, 2.7; 95% CI, 1.9-3.9) were increased. Separate analyses of the individual diseases showed higher frequencies in CAH of hypertension, hyperlipidemia, atrial fibrillation, venous thromboembolism, obesity, diabetes (mainly type 2), obstructive sleep disorder, thyrotoxicosis, and hypothyroidism. Similar results were seen in the stratified groups. On the subgroup level, females were generally more affected (especially I172N and the nonclassic group), as were males with the null genotype. CONCLUSIONS: CAH was associated with excess cardiovascular and metabolic morbidity but the mechanism is not certain as the glucocorticoids were not assessed. Hypothyroidism and obesity may be an effect of close observation. However, more severe conditions were presumably detected equally in patients and controls. Screening for diabetes and other metabolic disorders that increase cardiovascular risk is important.

Increased mortality in patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency
- 2014
-
In: The Journal of Clinical Endocrinology & Metabolism. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 0021-972X .- 1945-7197.
-
Journal article (peer-reviewed)abstract
- Context: Reports on mortality in patients with congenital adrenal hyperplasia (CAH) are lacking. Objective: To study mortality and causes of death in CAH. Design, Setting and Participants: We studied patients with CAH (21-hydroxylase deficiency, n=588; CYP21A2 mutations known, >80%), and compared them with controls (n=58800). Data were derived through linkage of national population-based registers. Main Outcome Measures: Mortality and causes of death. Results: The mean age of death was 41.2±26.9 years in CAH patients and 47.7±27.7 years in controls (P<0.001). Among CAH patients 23 (3.9%) had deceased compared to 942 (1.6%) of controls. The hazard ratio (and 95% confidence interval) of death was 2.3(1.2-4.3) in CAH males and 3.5(2.0-6.0) in CAH females. Including only patients born 1952-2009, gave similar total results but only patients with salt-wasting or with unclear phenotype had an increased mortality. The causes of death in CAH patients were adrenal crisis (42%), cardiovascular (32%), cancer (16%), and suicide (10%). There were seven additional deaths in CAH individuals with incomplete or reused personal identification number that could not be analyzed using linkage of registers. Of the latter all except one were deceased before the introduction of neonatal screening in 1986 and most of them in the first weeks of life, probably in an adrenal crisis. Conclusions: CAH is a potentially lethal condition and was associated with excess mortality due to adrenal crisis. The salt-wasting phenotype seemed to have worse outcome also in children and adults due to adrenal crisis and not only before the introduction of neonatal screening.

Increased Prevalence of Accidents and Injuries in Congenital Adrenal Hyperplasia : A Population-Based Cohort Study
- 2024
-
In: Journal of Clinical Endocrinology and Metabolism. - : Oxford University Press. - 0021-972X .- 1945-7197. ; 109:3, s. e1175-e1184
-
Journal article (peer-reviewed)abstract
- CONTEXT: It has been suggested that injuries and accidents are increased in females with congenital adrenal hyperplasia (CAH), but the prevalence is unclear.OBJECTIVE: To study the prevalence of injuries and accidents in females and males with CAH.DESIGN, SETTING, AND PARTICIPANTS: Patients with CAH (n = 714, all 21-hydroxylase deficiency) were compared with matched controls (n = 71,400). Data were derived by linking National Population-Based Registers.MAIN OUTCOME MEASURES: Prevalence of injuries and accidents.RESULTS: Mean age was 29.8 ± 18.4 years. Injuries were more prevalent in patients with CAH than in controls (RR 1.34, 95%CI 1.24-1.44), and this was found in both sexes (females: 1.43, 1.29-1.58; males: 1.25, 1.12-1.38). In the classical phenotype, the prevalence of injuries was higher, especially in females but not in the non-classic phenotype. In the genotype groups, injuries were mainly increased in females. Head injuries were increased in all patients with CAH and in the different phenotypes and were mainly driven by females. More patients with CAH born before the introduction of neonatal screening had had an injury compared to controls (1.48, 1.35-1.62), this was seen in both sexes. In patients with CAH born after the introduction of screening, the prevalence of injuries was overall increased (1.20, 1.07-1.35), and in females with CAH but not in males. Accidents showed a similar pattern to injuries in all comparisons.CONCLUSIONS: Patients with CAH had an increased prevalence of both injuries and accidents, especially in females and in those born before the neonatal screening program. Patients with NC phenotype were hardly affected.

-
Journal article (peer-reviewed)abstract
- Context:Reports on psychiatric morbidity in males with congenital adrenal hyperplasia (CAH) are lacking.Objective:To study psychiatric disorders in CAH males.Design, Setting and Participants:We studied males with CAH (21-hydroxylase deficiency, n=253; CYP21A2 mutations known, n=185), and compared them with controls (n=25300). Data were derived through linkage of national population-based registers. We assessed the subgroups of CYP21A2 genotype separately (null, I2splice, I172N, P30L and NC), as well as outcomes before and after the introduction of national neonatal screening in 1986.Main Outcome Measures:Psychiatric disorders including attempted and completed suicide (suicidality).Results:Psychiatric disorders (suicidality not included), suicidality and alcohol misuse were increased in CAH males compared with controls (OR 1.5, 2.3, and 1.9; 95%CI 1.1-2.2, 1.1-5.0, and 1.0-3.5). In the null genotype group, no increased rates were seen; in the I2splice group, psychiatric disorders, personality disorders and alcohol misuse were increased; in the I172N group suicide attempt and drug misuse were increased; and in the P30L and NC group psychotic disorders were increased. In CAH males born before the neonatal screening, the rate of psychiatric disorders and suicidality were increased, but only psychotic disorders in those born after. There was no increased risk for any neurodevelopmental disorder.Conclusions:CAH males have an increased psychiatric morbidity. Psychiatric morbidity was not raised in the most severe genotype group. Late diagnosis of CAH may explain some of the findings. Those born before the introduction of neonatal screening were more affected, which may be explained by the higher age.

- CONTEXT: Gender-atypical behavior has been described in young girls as well as in women with congenital adrenal hyperplasia (CAH) due to a CYP21A2 deficiency. OBJECTIVE: The aim of the study was to assess health-related, psychosexual, and psychosocial parameters and correlate the results to CYP21A2 genotype. DESIGN AND PARTICIPANTS: Sixty-two Swedish women with CAH and age-matched controls completed a 120-item questionnaire and a validated quality of life instrument [psychological general well-being (PGWB) formula] to identify psychosexual and psychosocial parameters. The patients were divided into four CYP21A2 genotype groups. RESULTS: The women with CAH held more male-dominant occupations (30%) compared to controls (13%) (P = 0.04), especially those in the null genotype group (55%) (P = 0.006). They also reported a greater interest in rough sports (74%) compared to controls (50%) (P = 0.007). Eight women with CAH (14%) reported a prime interest in motor vehicles, compared to none of the controls (P = 0.002). Non-heterosexual orientation was reported by 19% of women with CAH (P = 0.005), 50% in the null genotype group (P = 0.0001), 30% in I2 splice (NS), and 5% in I172N (NS). PGWB total score did not differ between patients and controls. CONCLUSION: We identified increased gender-atypical behavior in women with CAH that could be correlated to the CYP21A2 genotype. This speaks in favor of dose-dependent effects of prenatal androgens on the development of higher brain functions. The impact of the disease on upbringing and interpersonal relationships did not correlate with disease severity, indicating that other factors, such as coping strategies, are important for psychosocial adaptation. This illustrates the need for psychological support to parents and patients.

- Both prenatal and circulating testosterone and other androgens have been suggested to influence the individual's propensity to commit crime, but empirical evidence is limited and inconsistent. Congenital Adrenal Hyperplasia (CAH) and Polycystic Ovary Syndrome (PCOS) are both hyperandrogenic conditions but with an important difference; whereas subjects with CAH are exposed to high concentrations of androgens in utero, women with PCOS are subjected to high androgens in adulthood. Comparing these groups can therefore yield important insights of androgenic effects on behavior. In the current study, information on medical diagnoses and convicted crimes were gathered from Swedish population-based registers. The associations between diagnoses of CAH or PCOS and any crime, violent crime or sex crime were estimated with conditional logistic regression. Results showed that CAH in women and men did not predict criminality, whereas an increased risk for any crime and violent crime was found in PCOS women. Our findings indicate that female hyperandrogenism in adulthood, but not prenatal hyperandrogenism, is associated with risk for criminal behavior. Further research into hyperandrogenic conditions holds opportunities to deepen our understanding of the etiology of crime and psychopathology. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

- Aim: To investigate the effects of prenatal dexamethasone (DEX) exposure on gender role behaviour. Methods: The participants were 25 of the 40 children (62%, mean age 11 years) at risk for CAH treated with DEX prenatally during the years 1985-1995 in Sweden. The control group consisted of 35 sex- and age-matched healthy children. A new inventory, the Karolinska Inventory of Gender Role Behaviour (KI-GRB), was developed to assess directly school-age children's behaviour, and was evaluated using a separate sample of 160 school-age children. Results: DEX-treated CAH-unaffected boys showed more neutral behaviours than the controls (p = 0.04), while the DEX-treated CAH-unaffected girls did not differ from the controls after adjusting for the site of residence. There was a larger variation in the behaviour of the DEX-treated boys (p < 0.05) and a tendency for less-masculine behaviours in the DEX-treated CAH-unaffected children (p = 0.13). There were no between-group differences in the feminine behaviours. Recalculation of the analyses including the CAH-affected children showed analogous results. Conclusions: This pilot study indicates that the gender role behaviour may be affected in boys as an effect of DEX exposure in early pregnancy. Larger retrospective studies are needed for more conclusive results.

- Objectives: To investigate the long-term effects of prenatal treatment of congenital adrenal hyperplasia (CAH) with emphasis on behavioural problems and temperament. Design: A population-based long-term follow-up study of Swedish children at risk for virilising CAH, who had received treatment prenatally with dexamethasone (DEX). The questionnaire-based follow-up was performed when the children had reached school age. Methods: Standardised parent-completed questionnaires were used to evaluate adaptive functioning, behavioural/emotional problems and psychopathology, social anxiety and temperament in DEX-exposed school-aged children (n=26) and matched controls (n=35). In addition, the association between parental questionnaires and children's self-ratings was investigated. Results: There were no statistically significant differences between DEX-exposed children and controls in measures of psychopathology, behavioural problems and adaptive functioning. In a questionnaire on temperamental traits, DEX-exposed children were described by their parents as being more sociable than controls (P=0.042). The correlation analysis showed only modest parent–child agreement on social anxiety, i.e. the increased social anxiety in children's self-ratings was not confirmed by their parents. Conclusions: DEX-treated children showed good overall adjustment. The parent–child agreement with respect to social anxiety was modest, highlighting the importance of multiple information sources and assessment methods. The clinical significance of the observed difference in sociability cannot be determined within the frameworks of this study. Additional studies of larger cohorts are essential to make more decisive conclusions on the safety of the treatment. Until then, it is important that parents are thoroughly informed about the benefits and potential risks and uncertainties of this controversial treatment.

Journal article (peer-reviewed)abstract
- EDC-mediated coupling has frequently been utilized to poly(ethylene glycol) functionalize (PEGylate) cellulose-based materials, but no work has previously been reported on the direct N-(3-dimethylaminopropyl)-N-ethylcarbodiimide (EDC)-mediated PEGylation of cellulose nanofibrils (CNF). Herein, we report the first study where CNF has been directly sterically stabilized with amine-terminated PEG employing N-hydroxysuccinimide (NHS)-assisted EDC-coupling. This work has shown that this coupling reaction is highly sensitive to the reaction conditions and purification procedures, and hence an optimized coupling protocol was developed in order to achieve a reaction yield. Elemental analysis of the nitrogen content also showed the successful PEGylation. It was also shown that a surprisingly low PEGylation (1%) is sufficient to significantly improve the colloidal stability of the PEGylated samples, which reached dispersion-arrested-state-transitions at higher concentrations than neat CNF. The colloidal stability was preserved with increasing ionic strength, when comparably long polymer chains were grafted, targeting only 1% PEGylation.
