Abstract
OBJECTIVE To investigate the metabolic, cardiovascular, and neuropsychological phenotype, quality of life (QoL), and hormonal regulation in individuals with congenital adrenal hyperplasia (CAH), a group of autosomal recessive disorders characterized by impaired synthesis of cortisol in the adrenal cortex and, if untreated compensatory hyperandrogenism. CAH is associated with an increased cardiovascular and metabolic morbidity, possibly due to overtreatment with glucocorticoids, leading to weight gain, insulin resistance, and metabolic syndrome. DESIGN, PARTICIPANTS, MEASUREMENTS Thirty-seven individuals with CAH and 33 age- and sex-matched controls were evaluated at a single centre at Aarhus University Hospital with echocardiography, electrocardiogram, 24-h blood pressure, biochemistry, anthropometrics, and autism spectrum, anxiety, depression, personality, cognitive failures, and QoL were assessed using questionnaires. RESULTS CAH individuals had lower height than controls (170.5 vs. 182.9 cm in males and 160.2 vs. 170.1 cm in females, p < 0.01). Compared with female controls, females with CAH had higher haemoglobin (8.8 vs. 8.2 mmol/L, p = 0.003) and BMI (29.7 vs. 25.5 kg/m2, p = 0.006), reduced insulin sensitivity (HOMA-IR): 2.7 vs. 1.9, p = 0.018), prolonged E-wave deceleration time (193 vs. 174 cm, p = 0.015), and E/é ratios (5.4 vs. 4.5, p = 0.017), and lower self-reported QoL. Males with CAH had more cognitive complaints (p = 0.034) and higher autistic scores (19.9 vs. 14.9; p = 0.068) compared with male controls. More individuals with CAH than controls reported writing problems. CONCLUSION A sex-specific comorbidity profile is evident in CAH, with females presenting with decreased metabolic and overall self-reported health, whereas males with CAH presented with increased cognitive complaints and autistic traits.

Abstract
INTRODUCTION The presence of Y-chromosomal material in females with Turner syndrome (TS) is a well-established risk factor for developing gonadoblastoma and malignant transformations hereof. However, these events are rarely seen in TS patients with no Y-chromosomal material. Thus, it is the current understanding that parts of the Y-chromosome are essential for malignant transformation of gonadoblastoma in the dysgenetic gonad. METHODS We report a case of a TS female with an apparent 46,X,idic(Xq) karyotype, who was diagnosed with a metastatic dysgerminoma. Whole exome sequencing of tumor and blood, along with RNA sequencing of the tumor, was performed to comprehensively search for cryptic Y-chromosomal material and pathogenic variants. RESULTS No Y-chromosomal material was detected in neither tumor nor blood. Whole exome sequencing of DNA and RNA revealed a pathogenic somatic gain-of-function mutation in KIT and a pathogenic missense mutation in MTOR. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy, followed by adjuvant chemotherapy. Unfortunately, she died due to chemotherapy-induced pneumonitis seven months after initial diagnosis. CONCLUSION Females with TS can develop metastatic dysgerminoma even in the absence of Y-chromosomal material. This questions the current understanding of Y-chromosomal material being essential for the malignant transformation of a gonadoblastoma in the dysgenetic gonad.

Abstract
BACKGROUND Structural abnormalities as well as minor variations of the Y chromosome may cause disorders of sex differentiation or, more frequently, azoospermia. This study aimed to determine the prevalence of loss of Y chromosome material within the spectrum ranging from small microdeletions in the azoospermia factor region (AZF) to complete loss of the Y chromosome in azoospermic men. RESULTS Eleven of 865 azoospermic men (1.3%) collected from 1997 to 2022 were found to have a karyotype including a 45,X cell line. Two had a pure 45,X karyotype and nine had a 45,X/46,XY mosaic karyotype. The AZF region, or part of it, was deleted in eight of the nine men with a structural abnormal Y-chromosome. Seven men had a karyotype with a structural abnormal Y chromosome in a non-mosaic form. In addition, Y chromosome microdeletions were found in 34 men with a structural normal Y chromosome. No congenital malformations were detected by echocardiography and ultrasonography of the kidneys of the 11 men with a 45,X mosaic or non-mosaic cell line. CONCLUSIONS In men with azoospermia, Y chromosome loss ranging from small microdeletions to complete loss of the Y chromosome was found in 6.1% (53/865). Partial AZFb microdeletions may give a milder testicular phenotype compared to complete AZFb microdeletions.

Abstract
OBJECTIVE Cardiovascular complications and congenital malformations are known traits in Turner syndrome (TS), which increases mortality. Women with TS have varying phenotype and cardiovascular risks. A biomarker assessing the risk for cardiovascular complications could potentially reduce mortality in high-risk TS and reduce screening in TS participants with low cardiovascular risk. DESIGN, PATIENTS, PARTICIPANTS AND MEASUREMENTS As part of a study initiated in 2002, 87 TS participants and 64 controls were invited to magnetic resonance imaging of the aorta, anthropometry, and biochemical markers. TS participants were re-examined thrice lastly in 2016. The focus of this paper is the additional measurements of transforming growth factor beta (TGFβ), matrix metalloproteinase (MMP's), tissue inhibitor of matrix metalloproteinase (TIMP), peripheral blood DNA and their associations with TS and the cardiovascular risk and congenital heart disease. RESULTS TS participants had lower TGFβ1 and TGFβ2 values compared to controls. snp11547635 heterozygosity was not associated with any biomarkers but was associated with increased risk of aortic regurgitation. TIMP4 and TGFβ1 were correlated with the aortic diameter at several measuring positions. During follow-up, the antihypertensive treatment decreased the descending aortic diameter and increased TGFβ1 and TGFβ2 levels in TS. CONCLUSION TGFβ and TIMP's are altered in TS and may play a role in the development of coarctation and dilated aorta. snp11547635 heterozygosity was not found to impact biochemical markers. Further studies should investigate these biomarkers to further unravel the pathogenesis of the increased cardiovascular risk in TS participants.

Abstract
Context Turner syndrome (TS) is a rare genetic syndrome with an increased mortality, mainly attributed to cardiovascular disease. Objective This work aimed to investigate and correlate the lipid profile in adult women with TS to clinical characteristics. Methods A 12-year prospective cohort study, including 4 study visits, was conducted at a specialist hospital. A total of 102 women with TS qualified for inclusion. Excluding missing variables and participants lost to follow-up, 86 women (mean age 38.1 years; range, 18.4-62.1 years) were included in this study. Fifty-three women completed the study. Repeated-measurement analysis was performed, using total cholesterol (Total-C), low-density lipoprotein (LDL), triglycerides (TGs), and high-density lipoprotein (HDL) as outcome variables and age, karyotype, body mass index (BMI), treatment with statins, antidiabetics, and hormone replacement therapy as explanatory variables. Principal component analysis (PCA) and partial least squares (PLS) analysis were performed at the first study visit. Results Hyperlipidemia was present in 30% of the TS cohort. Total-C increased with age (0.12 mmol/L/y; P = .016). LDL (P = .08), TGs (P = .14), and HDL (P = .24) were not associated with age. BMI significantly increased total-C (0.19 mmol/L/kg/m2; P = .006), LDL (0.63 mmol/L/kg/m2; P < .001), and TGs (0.80 mmol/L/kg/m2; P < .001) and decreased HDL (-0.59 mmol/L/kg/m2; P < .001). PCA and PLS analysis found correlations between weight and BMI and total-C, LDL, and TGs. Conclusion Hyperlipidemia is more prevalent in adult women with TS across adulthood compared to the background population. Total-C, LDL, TGs, and HDL were significantly associated with BMI characterizing the atherogenic profile in adult women with TS.

Abstract
OBJECTIVES To investigate sleep among men with Klinefelter syndrome (KS). METHOD We compared the sleep domains latency, disturbance, and efficiency in 30 men with KS (M age = 36.7 years, SD = 10.6) to 21 age-matched non-KS controls (M age = 36.8 years, SD = 14.4). Actigraphs were used to objectively measure sleep across 7 days and nights. Participants also completed a sleep diary over the same period, and the Pittsburgh Sleep Quality Index (PSQI). RESULTS The mean correlation between the objective and subjective sleep measures was lower for the KS sample (M r = .15) than for controls (M r = .34). Sleep disturbance was significantly larger in the KS sample, as measured by actigraphy (p = .022, d = 0.71) and the PSQI (p = .037, d = 0.61). In regression models predicting sleep domains from KS status, age, educational level, vocational status, IQ, and mental health, KS status was not a significant predictor. Higher age was associated with more actigraphy-measured sleep disturbance. Higher educational level and being employed were associated with better sleep efficiency. CONCLUSIONS Sleep disturbance may be a particular problem for men with KS and should be measured with complimentary methods.

Abstract
The genetic architecture of the QT interval, defined as the period from onset of depolarisation to completion of repolarisation of the ventricular myocardium, is incompletely understood. Only a minor part of the QT interval variation in the general population has been linked to autosomal variant loci. Altered X chromosome dosage in humans, as seen in sex chromosome aneuploidies such as Turner syndrome (TS) and Klinefelter syndrome (KS), is associated with altered QTc interval (heart rate corrected QT), indicating that genes, located in the pseudoautosomal region 1 of the X and Y chromosomes may contribute to QT interval variation. We investigate the dosage effect of the pseudoautosomal gene SLC25A6, encoding the membrane ADP/ATP translocase 3 in the inner mitochondrial membrane, on QTc interval duration. To this end we used human participants and in vivo zebrafish models. Analyses in humans, based on 44 patients with KS, 44 patients with TS, 59 male and 22 females, revealed a significant negative correlation between SLC25A6 expression level and QTc interval duration. Similarly, downregulation of slc25a6 in zebrafish increased QTc interval duration with pharmacological inhibition of KATP channels restoring the systolic duration, whereas overexpression of SLC25A6 shortened QTc, which was normalized by pharmacological activation of KATP channels. Our study demonstrate an inverse relationship between SLC25A6 dosage and QTc interval indicating that SLC25A6 contributes to QT interval variation.

Abstract
Turner syndrome (TS) is a chromosomal disorder that affects about 1 in 2500 female births and is characterized by the partial or complete absence of the second X chromosome. Depending on karyotype, TS is associated with primary ovarian insufficiency (POI). Approximately 50% of girls with a mosaic 45, X/46, XX karyotype may enter puberty spontaneously, but only 5-10% of women with TS achieve pregnancy without egg donation. In this review, we will evaluate the clinical use of markers of ovarian function in TS patients. Based on longitudinal studies of serum concentrations of reproductive hormones as well as ovarian morphology in healthy females and patients with TS, we will evaluate how they can be applied in a clinical setting. This is important when counseling patients and their families about future ovarian function essential for pubertal development and fertility. Furthermore, we will report on 20 years of experience of transition from pediatric to gynecological and adult endocrinological care in our center at Rigshospitalet, Copenhagen, Denmark.

Abstract
BACKGROUND Men with Klinefelter syndrome (KS) are routinely offered testosterone replacement therapy (TRT) suggested to potentially promote platelet aggregation and increase cardiovascular risk. OBJECTIVE We investigated platelet aggregation in men with KS before and during TRT. MATERIALS AND METHODS Forty-one adult men with KS participated, of which 20 had no history of TRT at baseline, with 15 completing follow-up after 18 months TRT. Further, we included 21 adult men with KS on long-term TRT (>10 years) and a male reference population. We assessed platelet impedance aggregometry using adenosine diphosphate (6.5 μM), thrombin-receptor-activating-peptide-6 (TRAP 32 μM), and arachidonic acid (ASPI 0.5 mM) as agonists in KS compared to a male reference population and stratified by route of TRT administration. RESULTS Platelet aggregation among men with KS at baseline or during TRT was not increased compared with the male reference population. For all three agonist, no change was seen in platelet aggregation in KS at follow-up compared with baseline (p ≥ 0.2). Platelet aggregation was not associated with total testosterone and furthermore, platelet count was not affected by treatment with testosterone. Men with KS treated with testosterone gel showed slightly increased TRAP- and ASPI-induced platelet aggregation compared with those treated with testosterone injection (p = 0.02 and p = 0.04, respectively). DISCUSSION AND CONCLUSIONS We observed normal platelet aggregation in men with KS before TRT and following both short and long term treatment. Our findings do not support an independent role of platelets in driving the cardiovascular risk in KS.

Abstract
CONTEXT Women with Turner syndrome (TS) suffer from hypergonadotropic hypogonadism, causing a deficit in gonadal hormone secretion. As a consequence, these women are treated with estrogen from the age of 12 years, and later in combination with progesterone. However, androgens have been given less attention. OBJECTIVE To assess sex hormone levels in women with TS, both those treated and those nontreated with hormone replacement therapy (HRT), and investigate the impact of HRT on sex hormone levels. METHODS At Aarhus University Hospital, 99 women with TS were followed 3 times from August 2003 to February 2010. Seventeen were lost during follow-up. Control group 1 consisted of 68 healthy age-matched control women seen once during this period. Control group 2 consisted of 28 young, eumenorrheic women sampled 9 times throughout the same menstrual cycle. Serum concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), 17β-estradiol, estrone sulfate, DHEAS, testosterone, free androgen index, androstenedione, 17-OH progesterone, and sex hormone-binding globulin (SHBG) were analyzed. RESULTS All androgens, 17-OH progesterone, and sex hormone-binding globulin (SHBG) were 30% to 50% lower in TS compared with controls (P < 0.01). FSH, LH, and estrone sulfate were more than doubled in women with TS compared with controls (P < 0.02). Using principal component analysis, we describe a positive correlation between women with TS receiving HRT, elevated levels of SHBG, and decreased levels of androgens. CONCLUSION The sex hormone profile in TS reveals a picture of androgen deficiency, aggravated further by HRT. Conventional HRT does not normalize estradiol levels in TS.

Abstract
INTRODUCTION Early detection of salt-wasting congenital adrenal hyperplasia (SW-CAH) is important to reduce CAH-related morbidity. However, neonatal screening has shown to have a low positive predictive value (PPV), especially among preterm newborns. Here, the Danish CAH screening is evaluated by comparing incidence and morbidity of SW-CAH 10 years before and after introduction of screening. Furthermore, sensitivity, specificity, and PPV are determined. METHODS All newborns in Denmark born during 1999-2018 and diagnosed with SW-CAH were identified in the Danish National Patient Registry and/or at the Department of Clinical Genetics, Rigshospitalet. Newborns with a positive neonatal CAH screening were identified at Statens Serum Institut. Correct diagnosis was evaluated by medical record review. RESULTS A total of 65 newborns with SW-CAH were identified. The incidence of SW-CAH was 5:100,000 both before and after introduction of screening. Performance of sensitivity and specificity of the screening were 97% and 100%, respectively, and the PPV was 55% for the given period. Stratified according to gestational age, the PPV was 33% and 61% for pre -and fullterm newborns, respectively. Though not significant, the proportion of newborns presenting with SW-crisis decreased after introduction of screening from 29% versus 10% (p = 0.07). DISCUSSION AND CONCLUSION Neonatal screening for SW-CAH has not led to an increase in the incidence of newborns diagnosed with SW-CAH. The screening algorithm has effectively identified newborns with SW-CAH. After 2009, there was a tendency toward a lower proportion of newborns with SW-crisis at diagnosis. Finally, the study emphasizes the benefits of using second-tier screening as well as repeated screening of premature newborns.

Abstract
An Endo-European Reference Network guideline initiative was launched including 16 clinicians experienced in endocrinology, pediatric and adult and 2 patient representatives. The guideline was endorsed by the European Society for Pediatric Endocrinology, the European Society for Endocrinology and the European Academy of Andrology. The aim was to create practice guidelines for clinical assessment and puberty induction in individuals with congenital pituitary or gonadal hormone deficiency. A systematic literature search was conducted, and the evidence was graded according to the Grading of Recommendations, Assessment, Development and Evaluation system. If the evidence was insufficient or lacking, then the conclusions were based on expert opinion. The guideline includes recommendations for puberty induction with oestrogen or testosterone. Publications on the induction of puberty with follicle-stimulation hormone and human chorionic gonadotrophin in hypogonadotropic hypogonadism are reviewed. Specific issues in individuals with Klinefelter syndrome or androgen insensitivity syndrome are considered. The expert panel recommends that pubertal induction or sex hormone replacement to sustain puberty should be cared for by a multidisciplinary team. Children with a known condition should be followed from the age of 8 years for girls and 9 years for boys. Puberty induction should be individualised but considered at 11 years in girls and 12 years in boys. Psychological aspects of puberty and fertility issues are especially important to address in individuals with sex development disorders or congenital pituitary deficiencies. The transition of these young adults highlights the importance of a multidisciplinary approach, to discuss both medical issues and social and psychological issues that arise in the context of these chronic conditions.

Abstract
PURPOSE This study aimed to describe the comorbidity pattern in 47,XXX syndrome. METHODS This was a registry-based study of hospital diagnoses and prescribed medication in a nationwide cohort of females with 47,XXX (n = 103) and 46,XX/47,XXX (n = 57) in which they were compared with 16,000 age-matched general population female controls. RESULTS The overall occurrence of hospital diagnoses was significantly increased in females with 47,XXX when compared with controls (incidence rate ratio = 2.1, CI = 1.7-2.5), and when divided into 19 organ-specific groups, there was a significantly increased risk in the following 14 groups: infection, blood, endocrine and metabolism, mental, nervous system, eye, ear, respiratory, oral cavity and gastrointestinal, musculoskeletal, perinatal, congenital malformations, external factors, and "other." The risk of being prescribed any medication was not significantly increased in females with 47,XXX when compared with controls (hazard ratio = 1.2, CI = 0.9-1.4). However, when stratified according to medication groups, a significantly increased risk was detected in 4 of 13 groups. The overall occurrence of hospital diagnoses was also significantly increased when females with 46,XX/47,XXX were compared with controls (incidence risk ratio = 1.3, CI = 1.01-1.8), but generally, in comparison with controls, females with 46,XX/47,XXX were less severely affected than females with 47,XXX. CONCLUSION The 47,XXX syndrome is associated with an increased occurrence of a wide variety of diseases. Increased awareness of this may contribute to improve counseling and clinical assessment of these patients.

Abstract
BACKGROUND Liver and gastrointestinal diseases are frequent in women with Turner syndrome. However, their association with bleeding disorders, anaemia and the impact of hormone replacement therapy is unknown. AIMS To investigate the risk of liver and gastrointestinal diseases, haemorrhage and anaemia in women with Turner syndrome compared with the female background population, and the long-term impact of hormone replacement therapy on these conditions. METHODS One thousand one hundred and fifty-six women with Turner syndrome diagnosed during 1960-2014 were identified using the Danish Cytogenetic Central Registry and linked with personal-level data from the National Patient Registry and the Medication Statistics Registry. Statistics Denmark randomly identified 115 577 age-matched female controls. Negative binomial regression was used to analyse hospital discharge diagnoses. Medical prescriptions, mortality and the effect of hormone replacement therapy were estimated using stratified Cox regression. RESULTS Liver disease increased 13-fold (IRR 12.9 (95% CI 5.8-28.8)), due to toxic liver disease (IRR 8.0 (95% CI 1.8-35.4)), liver insufficiency (IRR 6.7 (95% CI 1.7-26.9)), fibrosis/cirrhosis (IRR 16.5 (95% CI 2.2-122.1)) and unspecified liver disease (IRR 10.6 (95% CI 4.4-25.3)). Furthermore, presence of abnormal liver enzymes increased 12-fold (IRR 12.4 (95% CI 4.2-36.6)). The risk of gastrointestinal haemorrhage (IRR 3.4 (95% CI 1.8-6.2)), anaemia (IRR 3.2 (95% CI 2.0-5.0)) and coagulation disorders (IRR 2.9 (95% CI 1.1-7.1)) was increased. However these diagnoses were not associated with inflammatory bowel disease. Gastrointestinal mortality was increased three-fold (HR 3.1 (95% CI 1.5-6.2)), partly due to death by liver disease (HR 3.0 (95% CI 1.1-8.2)), gastrointestinal haemorrhage (HR 29.6 (95% CI 3.1-285.1)) and capillary malformations (HR 18.6 (95% CI 4.1-85.0)). There was no effect of hormone replacement therapy on gastrointestinal risk but a trend towards a beneficial impact on liver diseases. CONCLUSIONS The risk of being diagnosed with liver disease was higher than previously reported. The occurrence of gastrointestinal haemorrhage and anaemia was increased in Turner syndrome. There was no effect of hormone replacement therapy on gastrointestinal risk but a trend towards a beneficial impact on liver diseases was detected.

Abstract
OBJECTIVE Although the overall risk of cancer is not increased in Turner syndrome, the pattern of cancer occurrence differs from the general population. We aim to describe the cancer morbidity pattern in Turner syndrome and evaluate the effect of long-term hormone replacement therapy (HRT). DESIGN Nationwide epidemiological study. METHODS 1156 females with Turner syndrome diagnosed during 1960-2014, were linked with data from the Danish National Patient Registry. Statistics Denmark randomly identified 115 578 female controls. Stratified Cox regression was used to analyze cancer morbidity, mortality and effect of HRT. RESULTS Overall risk of cancer was not elevated (hazard ratio 1.04 (95% CI: 0.80-1.36)). The risk of skin cancer and benign skin neoplasms was two-fold increased, while the risk of breast cancer was decreased (hazard ratio 0.4 (0.2-0.9)). Turner syndrome (45,X) had a two- to five-fold increased risk of benign CNS tumors, colon and rectal cancers, benign skin neoplasms and skin cancer. Turner syndrome women with a 45,X/46,XX karyotype had an increased risk of tongue cancer. HRT had no impact on the risk of any cancer investigated in this study. CONCLUSIONS The lack of one X chromosome might play a role in skin neoplasms, CNS tumors, colon and rectal cancers. The risk of breast cancer is lower than in the general population. Long-term HRT during the premenopausal age range seems not to exert a cancerous effect in Turner syndrome. Increased vigilance concerning specific types of cancer in Tuner syndrome harboring a 45,X karyotype is needed.

Abstract
Klinefelter syndrome (47,XXY) is a frequent chromosomal disorder among males, often presenting with hypergonadotropic hypogonadism, small firm testicles, metabolic disorders, neurocognitive challenges, and increased height. Neurologic disorders such as epilepsy, seizures, and tremor as well as psychiatric disorders are also seen more frequently. The neurocognitive deficits seen are present in many areas of cognition, typically affecting general cognitive abilities, language, and executive functioning. Also, social dysfunction is frequent. Dyslexia is present in more than half of all males. Brain imaging studies generally show a typical pattern, with many nuclei and brain areas being smaller than among controls. However, it has not been possible to link the brain alterations found in imaging studies with the neurocognitive profile. The genetics underlying the phenotypic traits found among males with Klinefelter syndrome still remains to be elucidated; however, recent studies have described pervasive changes in the methylome and transcriptome and new and interesting candidate genes have been pinpointed, but their involvement in the phenotype of Klinefelter syndrome has not been proven.

Abstract
MicroRNAs (miRNA) are small-non coding RNAs endowed with great regulatory power, thus playing key roles not only in almost all physiological pathways, but also in the pathogenesis of several diseases. Surprisingly, genomic distribution analysis revealed the highest density of miRNA sequences on the X chromosome; this evolutionary conserved mammalian feature equips females with a larger miRNA machinery than males. However, miRNAs contribution to some X-related conditions, properties or functions is still poorly explored. With the aim to support and focus research in the field, this review analyzes the literature and databases about X-linked miRNAs, trying to understand how miRNAs could contribute to emerging gender-biased functions and pathological mechanisms, such as immunity and cancer. A fine map of miRNA sequences on the X chromosome is reported, and their known functions are discussed; in addition, bioinformatics functional analyses of the whole X-linked miRNA targetome (predicted and validated) were performed. The emerging scenario points to different gaps in the knowledge that should be filled with future experimental investigations, also in terms of possible implications and pathological perspectives for X chromosome aneuploidy syndromes, such as Turner and Klinefelter syndromes.

Abstract
Sex chromosome abnormalities (SCAs) are characterized by gain or loss of entire sex chromosomes or parts of sex chromosomes with the best-known syndromes being Turner syndrome, Klinefelter syndrome, 47,XXX syndrome, and 47,XYY syndrome. Since these syndromes were first described more than 60 years ago, several papers have reported on diseases and health related problems, neurocognitive deficits, and social challenges among affected persons. However, the generally increased comorbidity burden with specific comorbidity patterns within and across syndromes as well as early death of affected persons was not recognized until the last couple of decades, where population-based epidemiological studies were undertaken. Moreover, these epidemiological studies provided knowledge of an association between SCAs and a negatively reduced socioeconomic status in terms of education, income, retirement, cohabitation with a partner and parenthood. This review is on the aspects of epidemiology in Turner, Klinefelter, 47,XXX and 47,XYY syndrome.

Abstract
47,XXX (triple X) and Turner syndrome (45,X) are sex chromosomal abnormalities with detrimental effects on health with increased mortality and morbidity. In karyotypical normal females, X-chromosome inactivation balances gene expression between sexes and upregulation of the X chromosome in both sexes maintain stoichiometry with the autosomes. In 47,XXX and Turner syndrome a gene dosage imbalance may ensue from increased or decreased expression from the genes that escape X inactivation, as well as from incomplete X chromosome inactivation in 47,XXX. We aim to study genome-wide DNA-methylation and RNA-expression changes can explain phenotypic traits in 47,XXX syndrome. We compare DNA-methylation and RNA-expression data derived from white blood cells of seven women with 47,XXX syndrome, with data from seven female controls, as well as with seven women with Turner syndrome (45,X). To address these questions, we explored genome-wide DNA-methylation and transcriptome data in blood from seven females with 47,XXX syndrome, seven females with Turner syndrome, and seven karyotypically normal females (46,XX). Based on promoter methylation, we describe a demethylation of six X-chromosomal genes (AMOT, HTR2C, IL1RAPL2, STAG2, TCEANC, ZNF673), increased methylation for GEMIN8, and four differentially methylated autosomal regions related to four genes (SPEG, MUC4, SP6, and ZNF492). We illustrate how these changes seem compensated at the transcriptome level although several genes show differential exon usage. In conclusion, our results suggest an impact of the supernumerary X chromosome in 47,XXX syndrome on the methylation status of selected genes despite an overall comparable expression profile.

Abstract
Background With increasing number of breast cancer survivors, more attention is drawn to long-term consequences of curative cancer treatment. Adjuvant treatment of breast cancer patients is associated with several unfavorable medical conditions, including dyslipidemia, insulin resistance, and obesity, potentially leading to cardiovascular disease and/or the metabolic syndrome. The aim of this explorative study is to investigate metabolic side effects of adjuvant treatment in breast cancer patients. Methods A cohort of 13 premenopausal and 20 postmenopausal women with early stage breast cancer were extensively examined prior to, immediately after and 1 year after ended adjuvant chemotherapy and compared with healthy controls (N = 36) matched by age and menopausal status. Repeated examinations included: anthropometric measures, DEXA scans, 24-h blood pressure measurements, and blood samples [high sensitivity CRP, lipid profile and glucose metabolism, including homeostatic model assessment (HOMA)]. Results At baseline, breast cancer patients were similar to healthy controls regarding all measures. From baseline to 1-year post-treatment specific components of the metabolic syndrome increased significantly in premenopausal breast cancer patients; body fat (P = 0.01), triglycerides (P = 0.03), waist circumference (P = 0.008) and diastolic blood pressure (P = 0.04). In postmenopausal patients, waist circumference also increased significantly (P = 0.03), and High density lipoprotein (HDL) cholesterol decreased significantly (P = 0.05). Conclusions Specific components of the metabolic syndrome changed significantly during chemotherapy in early stage breast cancer patients. After 1 year, several key parameters remained pathologically changed. Premenopausal breast cancer patients seemed to be especially prone to develop these unfavorable changes.

Abstract
Background Knowledge on the prevalence of sex chromosome abnormalities (SCAs) is limited, and delayed diagnosis or non-diagnosis of SCAs are a continuous concern. We aimed to investigate change over time in incidence, prevalence and age at diagnosis among Turner syndrome (TS), Klinefelter syndrome (KS), Triple X syndrome (Triple X) and Double Y syndrome (Double Y). Methods This study is a nationwide cohort study in a public health care system. The Danish Cytogenetic Central Registry (DCCR) holds information on all karyotypes performed in Denmark since 1961. We identified all individuals in the DCCR with a relevant SCA during 1961–2014; TS: n = 1156; KS: n = 1235; Triple X: n = 197; and Double Y: n = 287. From Statistics Denmark, which holds an extensive collection of data on the Danish population, complete data concerning dates of death and migrations in and out of Denmark were retrieved for all individuals. Results The prevalence among newborns was as follows: TS: 59 per 100,000 females; KS: 57 per 100,000 males; Triple X: 11 per 100,000 females; and Double Y: 18 per 100,000 males. Compared with the expected number among newborns, all TS, 38% of KS, 13% of Triple X, and 18% of Double Y did eventually receive a diagnosis. The incidence of TS with other karyotypes than 45,X (P < 0.0001), KS (P = 0.02), and Double Y (P = 0.03) increased during the study period whereas the incidence of 45,X TS decreased (P = 0.0006). The incidence of Triple X was stable (P = 0.22). Conclusions The prevalence of TS is higher than previously identified, and the karyotypic composition of the TS population is changing. Non-diagnosis is extensive among KS, Triple X and Double Y, whereas all TS seem to become diagnosed. The diagnostic activity has increased among TS with other karyotypes than 45,X as well as among KS and Double Y.

Abstract
Turner syndrome (TS) is associated with an increased frequency of autoimmunity. Frequently observed autoimmune diseases in TS are also seen in the autoimmune polyendocrine syndrome type I (APS I), of which Addison disease is a key component. An overlapping antibody profile between TS and APS I could be considered. The aim of this work was to study women with TS regarding 21-hydroxylase (21-OH) antibodies and interferon omega (IFN-ω) antibodies, a highly specific marker for APS I, to determine if there are immunological overlaps between TS and APS I. Blood samples from 141 TS were assayed for 21-OH antibodies and IFN-ω antibodies using in-vitro-transcribed and translated autoantigen. Indices with a cut-off point of 57 and 200 for 21-OH antibody and IFN-ω antibody were used as reference. The median age of TS was 31·6 years (range = 11·2-62·2). Positive indices of 21-OH antibodies were present in six TS (4%), with a mean of 144·8 (range = 60-535). None had apparent adrenal insufficiency. There was no age difference comparing 21-OH antibody-positive TS (median age = 33·9 years, range = 17·7-44·7) and 21-OH antibody-negative TS (median age = 31·6 years, range = 11·2-62·2) (P = 0·8). No TS was positive for IFN-ω antibodies (mean = 42·4, range = -435-191). No overlapping autoimmune profile between TS and APS I was found. Autoimmunity against 21-OH among TS patients was more prevalent than previously identified, suggesting an increased risk of adrenal failure in TS. However, whether adrenal impairment will develop remains unknown.

Abstract
Klinefelter syndrome (KS) (47, XXY) is the most common sex chromosome disorder, with a prevalence of 1 in every 660 newborn males. Despite the profound adverse effects of anxiety and depression, and their greater prevalence in KS populations, no research has been conducted to date to identify the determinants of anxiety and depression among patients with KS. We examined the relationships between personality traits, social engagement, and anxiety and depression symptoms among KS patients (n = 69) and a group of male controls (n = 69) matched for age and years of education. KS patients experienced more anxiety and depression symptoms than control participants. Neuroticism was the strongest and most consistent mediator between KS and both anxiety and depression symptoms. This research suggests that neuroticism may play a central role in attention switching, anxiety and depression among patients with Klinefelter syndrome. The central role of neuroticism suggests that it may be used to help identify and treat KS patients at particularly high-risk for attention-switching deficits, anxiety and depression.

Abstract
Klinefelter syndrome (KS) has a prevalence ranging from 85 to 250 per 100.000 newborn boys making it the most frequent sex chromosome aneuploidy in the general population. The molecular basis for the phenotypic traits and morbidity in KS are not clarified. We performed genome-wide DNA methylation profiling of leucocytes from peripheral blood samples from 67 KS patients, 67 male controls and 33 female controls, in addition to genome-wide RNA-sequencing profiling in a subset of 9 KS patients, 9 control males and 13 female controls. Characterization of the methylome as well as the transcriptome of both coding and non-coding genes identified a unique epigenetic and genetic landscape of both autosomal chromosomes as well as the X chromosome in KS. A subset of genes show significant correlation between methylation values and expression values. Gene set enrichment analysis of differentially methylated positions yielded terms associated with well-known comorbidities seen in KS. In addition, differentially expressed genes revealed enrichment for genes involved in the immune system, wnt-signaling pathway and neuron development. Based on our data we point towards new candidate genes, which may be implicated in the phenotype and further point towards non-coding genes, which may be involved in X chromosome inactivation in KS.

Abstract
INTRODUCTION We present a case of an infertile male with 46,XX/46,XYchimerism fathering a child after ICSI procedure. METHODS Conventional cytogenetic analysis on chromosomes, derived from lymphocytes, using standard Q-banding procedures with a 450-550-band resolution and short-tandem-repeat analysis of 14 loci. RESULTS Analysis of 20 metaphases from lymphocytes indicated that the proband was a karyotypic mosaic with an almost equal distribution between male and female cell lines. In total, 12 of 20 (60%) metaphases exhibited a normal female karyotype 46,XX, while 8 of 20 (40%) metaphases demonstrated a normal male karyotype 46,XY. No structural chromosomal abnormalities were present. Out of 14 STR loci, two loci (D18S51 and D21S11) showed four different alleles in peripheral blood, buccal mucosal cells, conjunctival mucosal cells, and seminal fluid. In three loci (D2S1338, D7S820, and vWA), three alleles were detected with quantitative differences that indicated presence of four alleles. In DNA extracted from washed semen, four alleles were detected in one locus, and three alleles were detected in three loci. This pattern is consistent with tetragametic chimerism. There were no quantitative significant differences in peak heights between maternal and paternal alleles. STR-analysis on DNA from the son confirmed paternity. CONCLUSION We report a unique case with 46,XX/46,XY chimerism confirmed to be tetragametic, demonstrated in several tissues, with male phenotype and no genital ambiguity with oligospermia fathering a healthy child after IVF with ICSI procedure.

Abstract
BACKGROUND AND OBJECTIVES Modeling of glucose kinetics has to a large extent been based on models with plasma insulin as a known forcing function. Furthermore, population-based statistical methods for parameter estimation in these models have mainly addressed random inter-individual variations and not intra-individual variations in the parameters. Here we present an integrated whole-body model of glucose and insulin kinetics which extends the well-known two-compartment glucose minimal model. The population-based estimation technique allow for quantification of both random inter- and intra-individual variation in selected parameters using simultaneous data series on glucose and insulin. METHODS We extend the two-compartment glucose model into a whole-body model for both glucose and insulin using a simple model for the pancreas compartment which includes feedback of glucose on both insulin secretion and formation of insulin in pancreas. The model has 15 unknown parameters of which 8 have been selected for both intra- and inter-individual variations. The statistical technique for parameter estimation is based on first order conditional estimation. RESULTS The model has been evaluated on two datasets: Study group 1 includes 13 healthy subjects with 3-5 repeated IVGTT series of simultaneous plasma glucose and insulin measurements and Study group 2 includes 26 obese patients (3 subgroups: 10 type 2 diabetes (T2D), 7 impaired glucose tolerance (IGT) and 9 normal glucose tolerance (NGT)) with a single IVGTT series. In general the estimated population parameters compares well with reported values in similar studies. Overall the model fits the data series well and the random variation in the 8 selected parameters can account for both intra- and inter-individual variations in the data series. Simulation studies perform reasonable in response to either a slow glucose infusion or a staircase experiment with increasing glucose infusion. Furthermore, the parameters related to the pancreas compartment add useful interpretations in relation to discrimination between populations with varying degree of glucose intolerance. CONCLUSIONS We report a new and improved whole-body model of glucose and insulin kinetics which performs robustly under differing conditions and adds useful interpretations in relation to glucose intolerance.

Abstract
INTRODUCTION The determinants of cognitive deficits among individuals with Klinefelter syndrome (KS) are not well understood. This study was conducted to assess the impact of general intelligence, personality, and social engagement on cognitive performance among patients with KS and a group of controls matched for age and years of education. METHODS Sixty-nine patients with KS and 69 controls were assessed in terms of IQ, NEO personality inventory, the Autism Spectrum Quotient (AQ) scale, and measures of cognitive performance reflecting working memory and executive function. RESULTS Patients with KS performed more poorly on memory and executive-function tasks. Patients with KS also exhibited greater neuroticism and less extraversion, openness, and conscientiousness than controls. Memory deficits among patients with KS were associated with lower intelligence, while diminished executive functioning was mediated by both lower intelligence and less social engagement. CONCLUSION Our results suggest that among patients with KS, memory deficits are principally a function of lower general intelligence, while executive-function deficits are associated with both lower intelligence and poorer social skills. This suggests a potential influence of social engagement on executive cognitive functioning (and/or vice-versa) among individuals with KS, and perhaps those with other genetic disorders. Future longitudinal research would be important to further clarify this and other issues discussed in this research.

Abstract
Objective Routinely collected health data may be valuable sources for conducting research. This study aimed to evaluate the validity of algorithms detecting hypopituitary patients in the Danish National Patient Registry (DNPR) using medical records as reference standard. Study design and setting Patients with International Classification of Diseases (10th edition [ICD-10]) diagnoses of hypopituitarism, or other diagnoses of pituitary disorders assumed to be associated with an increased risk of hypopituitarism, recorded in the DNPR during 2000–2012 were identified. Medical records were reviewed to confirm or disprove hypopituitarism. Results Hypopituitarism was confirmed in 911 patients. In a candidate population of 1,661, this yielded an overall positive predictive value (PPV) of 54.8% (95% confidence interval [CI]: 52.4–57.3). Using algorithms searching for patients recorded at least one, three or five times with a diagnosis of hypopituitarism (E23.0x) and/or at least once with a diagnosis of postprocedural hypopituitarism (E89.3x), PPVs gradually increased from 73.3% (95% CI: 70.6–75.8) to 83.3% (95% CI: 80.7–85.7). Completeness for the same algorithms, however, decreased from 90.8% (95% CI: 88.7–92.6) to 82.9% (95% CI: 80.3–85.3) respectively. Including data of hormone replacement in the same algorithms PPVs increased from 73.2% (95% CI: 70.6–75.7) to 82.6% (95% CI: 80.1–84.9) and completeness decreased from 94.3% (95% CI: 92.6–95.7) to 89.7% (95% CI: 87.5–91.6) with increasing records of E23.0x. Conclusion The DNPR is a valuable data source to identify hypopituitary patients using a search criteria of at least five records of E23.0x and/or at least one record of E89.3x. Completeness is increased when including hormone replacement data in the algorithm. The consequences of misclassification must, however, always be considered.

Abstract
Low‐dose QT‐prolonging drugs may have detrimental effects on women with Turner's syndrome. Preventive measures would be to use potential QT‐prolonging drugs with precaution and ensure that both before and during treatment, ECGs are evaluated and drug treatment stopped if the QT interval increases.

Abstract
Klinefelter syndrome (47, XXY) (KS) is a genetic syndrome characterized by the presence of an extra X chromosome and low level of testosterone, resulting in a number of neurocognitive abnormalities, yet little is known about brain function. This study investigated the fMRI-BOLD response from KS relative to a group of Controls to basic motor, perceptual, executive and adaptation tasks. Participants (N: KS = 49; Controls = 49) responded to whether the words "GREEN" or "RED" were displayed in green or red (incongruent versus congruent colors). One of the colors was presented three times as often as the other, making it possible to study both congruency and adaptation effects independently. Auditory stimuli saying "GREEN" or "RED" had the same distribution, making it possible to study effects of perceptual modality as well as Frequency effects across modalities. We found that KS had an increased response to motor output in primary motor cortex and an increased response to auditory stimuli in auditory cortices, but no difference in primary visual cortices. KS displayed a diminished response to written visual stimuli in secondary visual regions near the Visual Word Form Area, consistent with the widespread dyslexia in the group. No neural differences were found in inhibitory control (Stroop) or in adaptation to differences in stimulus frequencies. Across groups we found a strong positive correlation between age and BOLD response in the brain's motor network with no difference between groups. No effects of testosterone level or brain volume were found. In sum, the present findings suggest that auditory and motor systems in KS are selectively affected, perhaps as a compensatory strategy, and that this is not a systemic effect as it is not seen in the visual system.

Abstract
CONTEXT Long-term safety of growth hormone (GH) treatment is an area of much debate. Studies including children treated with GH not only due to GHD, but also due to non-GHD causes like idiopathic short stature or like short stature in children born small for gestational age have suggested that GH treatment is associated with increased mortality or stroke. OBJECTIVE To study the impact of GH replacement on overall and cause-specific mortality in childhood-onset GHD (CO GHD) patients. DESIGN A nationwide population-based registry study on patients with CO GHD and general population controls matched on age and gender. Mortality hazard ratios (HRs) were computed comparing patients and controls, and comparing GH-replaced patients and non-GH-replaced patients, using Cox regression. Comparing GH- and non-GH-replaced patients HRs were adjusted for birth year, year of diagnosis, gender, irradiation, ACTH insufficiency and primary disease. PATIENTS AND CONTROLS A total of 494 patients with CO GHD each matched with 100 general population controls were included. RESULTS Mortality was substantially increased comparing patients with CO GHD and general population controls, HR = 7·51 (95% CI = 6·06-9·31). Comparing GH-replaced patients with non-GH-replaced patients mortality was significantly decreased in total (HR = 0·27, CI = 0·17-0·43) and due to malignancy (HR = 0·14, CI = 0·07-0·28) in GH-replaced patients. Adjusting for relevant confounders, this decrease remained significant both in total (HR = 0·56, CI = 0·32-0·96) and due to malignancy (HR = 0·33, CI = 0·16-0·69). Overall and cause-specific mortality was increased in both GH-replaced and non-GH-replaced patients compared to general population controls, but mortality was generally highest in non-GH-replaced patients. CONCLUSION The present data from a national cohort of patients with CO GHD do not support the suggestion that GH replacement is associated with increased mortality.

Abstract
Klinefelter syndrome (KS), though described more than 70 years ago, still imposes significant diagnostic challenges. Based on data from epidemiological studies, KS is associated with increased morbidity and mortality. Although the pathophysiology and etiology behind these observations are as yet not well understood, a significant contribution of hypogonadism, central to the syndrome, is traditionally suspected. However, other unknown effects inherent to the syndrome also seem to modify the disease pattern. Herein we show that KS is under-diagnosed since only roughly 25% of patients are diagnosed and the mean age of diagnosis is during adult life. KS is associated with increased morbidity resulting in loss of 2-5 years in lifespan with increased mortality from different diseases and a poor socioeconomic profile. Small testes, hypergonadothrophic hypogonadism and cognitive impairment are usually found. The accompanying hypogonadism can lead to altered body composition and a risk of developing metabolic syndrome, type 2 diabetes and cardiovascular disease. Cancer risk is generally not different from that observed in the background population, although specific cancers like breast cancer and extragonadal germ cell tumors are seen more frequently in KS. The mainstay of medical treatment is testosterone replacement therapy to both attenuate acute and long-term consequences of hypogonadism and possibly prevent the frequent comorbidity. We believe that the diagnostic challenges should be tackled more efficiently, while there is also a pressing need to generate better evidence for timing and the proper dose of testosterone replacement. We advocate for a multidisciplinary setup with the inclusion of pediatricians, speech therapists, general practitioners, psychologists, infertility specialists, urologists and endocrinologists.

Abstract
BACKGROUND An unfavourable cardiovascular and metabolic phenotype causes threefold excess mortality in Turner syndrome (TS), and perturbed cardiac substrate metabolism is increasingly recognized as a common component of cardiovascular and metabolic diseases. We therefore hypothesized that myocardial glucose uptake (MGU) is reduced in TS and that growth hormone (GH) treatment improves MGU. To this end, this controlled trial elucidates MGU in TS and the impact of 6 months of growth hormone treatment on MGU. METHODS AND RESULTS Women with TS (n = 9) were examined at baseline, sequentially treated with either Norditropin(®) SimpleXx or placebo and re-examined after 6 months. MGU and myocardial blood flow (MBF) were measured using 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography (FDG-PET) during a hyperinsulinaemic euglycaemic clamp (at baseline and 6 months). Blood pressure measurement, blood sampling, echocardiography and dual energy X-ray absorptiometry scan were also performed. Age-matched female controls (n = 9) were examined once. Baseline MGU was reduced in TS (0.24 ± 0.08 vs. 0.36 ± 0.13 μmol/g/min in controls; P = 0.036) despite similar insulin sensitivity (whole body glucose uptake (M-value): 9.69 ± 1.86 vs. 9.86 ± 2.58 mg/(min*kg) in controls; P = 0.9). Six months of GH carried no impact on MGU (0.25 ± 0.08 vs. 0.26 ± 0.12 μmol/g/min in the placebo group; P = 0.8). Plasma glucose, low-density cholesterol and triglycerides increased, while M-value and exercise capacity decreased during 6 months of GH treatment. CONCLUSION MGU is reduced in TS despite normal insulin sensitivity. GH treatment does not alter MGU despite decreased whole body insulin sensitivity. A perturbed cardiac glucose uptake appears to be a feature of TS.

Abstract
OBJECTIVE This study examined the effect of maternal pregestational type 1 diabetes on offspring primary school performance. RESEARCH DESIGN AND METHODS We performed a prospective combined clinical and register-based cohort study comparing primary school performance in offspring (n = 707) of women with pregestational type 1 diabetes with matched control offspring (n = 60,341). We also examined the association between HbA1c levels during pregnancy and later school performance among offspring born to women with pregestational type 1 diabetes. RESULTS Offspring of mothers with pregestational type 1 diabetes obtained similar school grades as control offspring when finishing primary school (regression coefficient [β] = -0.13; 95% CI = -0.30 to 0.03; P = 0.12). Adjusting for parental education also resulted in an insignificant difference between the two groups (β = -0.07; 95% CI = -0.23 to 0.09; P = 0.37). Among offspring of women with type 1 diabetes, increasing maternal HbA1c pregestationally and throughout the pregnancy was associated with lower average school grades. Offspring born to mothers with good glycemic control in the third trimester obtained higher average school grades compared with control offspring. The opposite applied to offspring born to mothers with inadequate glycemic control, who obtained significantly lower average school grades compared with control offspring. CONCLUSIONS Offspring of mothers with pregestational type 1 diabetes obtained similar average grades when finishing primary school compared with matched control offspring. Among offspring of women with type 1 diabetes, we found a consistent negative association between maternal HbA1c in pregnancy and primary school grades. However, whether this association reflects a direct causal influence of intrauterine hyperglycemia is uncertain.

Abstract
OBJECTIVE This study examined the long-term consequences for offspring born to mothers with pregestational type 1 diabetes regarding mortality, hospital admissions, and medication. We also examined the association between HbA1c levels during pregnancy and mortality and incidence of hospital admissions. RESEARCH DESIGN AND METHODS We performed a prospective combined clinical and register-based cohort study comparing mortality, hospital admissions, and use of medication in offspring (n = 1,326) of women with pregestational type 1 diabetes (index children) with matched control subjects (n = 131,884). We also examined the association between HbA1c levels during pregnancy and mortality and the incidence of hospital admissions. Participants were monitored from birth to the age of 13-21 years. RESULTS Overall mortality was significantly increased for index children (hazard ratio 2.10, 95% CI 1.33-3.30, P = 0.001). The incidence of hospital admissions for index children was significantly increased (incidence rate ratio [IRR] 1.45, 95% CI 1.38-1.53, P < 0.001), and this was the case for all age groups until the age of 15 years. The incidence of hospital admissions among index children was positively associated with maternal HbA1c before pregnancy and in the first trimester. In addition, the overall use of medication was increased in index children (IRR 1.13, 95% CI 1.07-1.19, P < 0.001). CONCLUSIONS Type 1 diabetes during pregnancy has long-term implications on the health of offspring, with increased mortality, incidence of hospital admissions, and use of medication. Among mothers with type 1 diabetes, glycemic regulation is positively associated with incidence of hospital admissions in offspring.

Abstract
BACKGROUND Cardiovascular disease is a cardinal trait of Turner syndrome (TS), causing half of the threefold excess mortality. As osteoprotegerin (OPG) is a potential biomarker of cardiovascular disease, this cross-sectional and prospective study aimed at elucidating OPG levels in TS and its relationship to aortic diameter as well as validated cardiovascular risk markers. METHODS Adult women with TS (n = 99) were examined thrice (mean follow-up 4·7 ± 0·5 years), and 68 age-matched healthy female controls were examined once. Aortic diameter was assessed by cardiovascular magnetic resonance. Twenty-four-hours blood pressure monitoring and biochemical assessments were also performed. RESULTS Osteoprotegerin levels (median with range) were lower in TS (777 [326-10 569] ng/l) compared with controls (979 [398-1987] ng/l; P < 0·05) and did not change during follow-up. The OPG concentration was higher among women with TS older than 50 years of age (996 [542-4996] vs 756 [326-10 569] ng/l; P < 0·05) with a trend towards a higher OPG in TS who were on antihypertensive medication (938 [490-2638] vs 752 [326-10 569] ng/l; P = 0·09). Contrary to controls, OPG levels correlated with BSA-indexed aortic diameter (r = 0·31-0·45; P < 0·05), age (r = 0·29; P < 0·05) and high-sensitivity C-reactive protein (r = 0·23; P = 0·02) and inversely with BSA (r = -0·20; P < 0·05), weight (r = -0·23; P < 0·05) and plasma oestradiol levels (r = -0·34; P < 0·05). CONCLUSION Levels of OPG are lower in TS and correlate with aortic diameter, age, BSA, weight and oestradiol in TS, but not controls. Future studies are needed to assess whether OPG may serve as a biomarker of aortic or cardiovascular disease in TS.

Abstract
CONTEXT GH deficiency is associated with changes in body composition, increased cardiovascular risk markers, and reduced bone mineral density. There seem to be multiple causes of the reported increased morbidity and mortality. OBJECTIVE The objective was to study the socioeconomic status in patients with adult-onset GH deficiency and its impact on mortality. DESIGN This is a nationwide registry study in which the socioeconomic status in adult-onset GH deficient patients was identified in the Danish registries and compared with controls matched on age and gender. The socio-economic status included cohabitation, education, income, parenthood, convictions, and retirement. PATIENTS AND CONTROLS All patients had adult-onset GH deficiency and were born between 1950 and 1980. Two-hundred seventy-six patients (53.6% men) and 25 717 controls were included. RESULTS GH-treated patients had a reduced mortality in total and due to malignancy compared with untreated patients. This difference remained after adjustment for cohabitation and education. Compared with the background population, the incidence of cohabitation, parenthood, and convictions was significantly reduced in patients, whereas education was unaffected. Retirement was significantly increased. CONCLUSIONS Mortality was increased in patients, especially among patients not treated with GH. In GH-treated patients, mortality was decreased in total and due to malignancy compared with untreated patients, even after adjustment for all possible measured confounders. The patients had an impaired socioeconomic profile on most parameters compared with controls. This study does not support the suggestion that GH replacement therapy causes increased mortality.

Abstract
Brain imaging in Klinefelter syndrome (47, XXY) (KS), a genetic disorder characterized by the presence of an extra X chromosome, may contribute to understanding the relationship between gene expression, brain structure, and subsequent cognitive disabilities and psychiatric disorders. We conducted the largest to date voxel-based morphometry study of 65 KS subjects and 65 controls matched for age and education and correlated these data to neuropsychological test scores. The KS patients had significantly smaller total brain volume (TBV), total gray matter volume (GMV) and total white matter volume (WMV) compared to controls, whereas no volumetric difference in cerebral spinal fluid (CSF) was found. There were no differences in TBV, GMV, WMV or CSF between testosterone treated KS (T-KS) and untreated KS (U-KS) patients. Compared to controls, KS patients had significantly decreased GMV bilaterally in insula, putamen, caudate, hippocampus, amygdala, temporal pole and frontal inferior orbita. Additionally, the right parahippocampal region and cerebellar volumes were reduced in KS patients. KS patients had significantly larger volumes in right postcentral gyrus, precuneus and parietal regions. Multivariate classification analysis discriminated KS patients from controls with 96.9% (p < 0.001) accuracy. Regression analyses, however, revealed no significant association between GMV differences and cognitive and psychological factors within the KS patients and controls or the groups combined. These results show that although gene dosage effect of having and extra X-chromosome may lead to large scale alterations of brain morphometry and extended cognitive disabilities no simple correspondence links these measures.

Abstract
CONTEXT Recently, new clinically important information regarding Klinefelter syndrome (KS) has been published. We review aspects of epidemiology, endocrinology, metabolism, body composition, and neuropsychology with reference to recent genetic discoveries. EVIDENCE ACQUISITION PubMed was searched for "Klinefelter," "Klinefelter's," and "XXY" in titles and abstracts. Relevant papers were obtained and reviewed, as well as other articles selected by the authors. EVIDENCE SYNTHESIS KS is the most common sex chromosome disorder in males, affecting one in 660 men. The genetic background is the extra X-chromosome, which may be inherited from either parent. Most genes from the extra X undergo inactivation, but some escape and serve as the putative genetic cause of the syndrome. KS is severely underdiagnosed or is diagnosed late in life, roughly 25% are diagnosed, and the mean age of diagnosis is in the mid-30s. KS is associated with an increased morbidity resulting in loss of approximately 2 yr in life span with an increased mortality from many different diseases. The key findings in KS are small testes, hypergonadotropic hypogonadism, and cognitive impairment. The hypogonadism may lead to changes in body composition and a risk of developing metabolic syndrome and type 2 diabetes. The cognitive impairment is mainly in the area of language processing. Boys with KS are often in need of speech therapy, and many suffer from learning disability and may benefit from special education. Medical treatment is mainly testosterone replacement therapy to alleviate acute and long-term consequences of hypogonadism as well as treating or preventing the frequent comorbidity. CONCLUSIONS More emphasis should be placed on increasing the rate of diagnosis and generating evidence for timing and dose of testosterone replacement. Treatment of KS should be a multidisciplinary task including pediatricians, speech therapists, general practitioners, psychologists, infertility specialists, urologists, and endocrinologists.

Abstract
OBJECTIVE Carotid intima-media thickness (IMT) may potentially supplement cardiovascular risk assessment in Turner syndrome (TS), where cardiovascular risk is high and appropriate risk stratification difficult. Knowledge of IMT in TS is scarce, and this study aimed to enhance insight into the cardiovascular risk marker. DESIGN, PATIENTS AND MEASUREMENTS IMT was cross-sectionally assessed by ultrasonography of the common carotid artery (cIMT) and carotid bulb (bIMT) in TS (n = 69, age 40 ± 10 years) and age-matched, healthy female controls (n = 67). Additional prospective IMT assessment was performed in TS over 2·4 ± 0·3 years. Metabolic biomarkers and 24-h ambulatory blood pressure were also assessed. RESULTS cIMT and bIMT (body surface area indexed) were increased in TS (P < 0·05) with 17-18% having IMTs that exceeded the 95th percentile of the controls (P < 0·05). Blood pressure, heart rate, glycosylated haemoglobin A1c and high-density lipoprotein cholesterol were increased in TS, where 43% received antihypertensive treatment. cIMT decreased during follow-up, coinciding with intensified cardiovascular risk prophylaxis, whereas bIMT was unchanged. In multiple regression analyses (R = 0·52-0·69, P < 0·05), baseline IMT in TS increased with age, blood pressure and cholesterol as well as in the presence of diabetes whilst IMT was inversely associated with duration of oestrogen replacement. In an analogue analysis, the prospective changes in cIMT (R = 0·37, P < 0·05) were beneficially influenced by antihypertensive treatment and oestrogen therapy and adversely by the presence of diabetes. CONCLUSION Carotid IMT was abnormal in TS and negatively influenced by age, metabolic biomarkers, blood pressure and short duration of oestrogen treatment. Attention to common cardiovascular and endocrine risk markers over more than 2 years appeared to influence IMT beneficially.

Abstract
OBJECTIVE Childhood onset GH deficiency (CO-GHD) is associated with increased morbidity and mortality; however, the patients' socioeconomic profile as adults is not fully known. DESIGN Register study using Danish nationwide registries. Two hundred and sixty GHD males and 156 GHD females and 25,358 male and 15,110 female controls were included. METHODS Information was obtained concerning cohabitation, parenthood, education, income, retirement, convictions, and death. Income was analyzed using conditional logistic regression, and other outcomes were analyzed using Cox regression. Subgroups of GHD patients with malignant tumors, craniopharyngioma, idiopathic GHD, and others were investigated separately. RESULTS Both male and female GHD patients had a significantly worse outcome on all studied socioeconomic parameters. Fewer GHD patients lived in partnerships and entered them later (male hazard ratio (HR): 0.31; female HR: 0.33), had fewer parenthoods (male HR: 0.26; female HR: 0.26), lower educational level (male HR: 0.58; female HR: 0.48), lower income, higher risk of retirement (male HR: 13.4; female HR: 24.2), and fewer convictions (male HR: 0.67; female HR: 0.49). Mortality was increased (male HR: 10.7; female HR: 21.4). Adjusted for marital and educational status, male HR of death was 5.2 and female HR 10.5. Patients with idiopathic GHD had a socioeconomic profile similar to controls. CONCLUSION The primary causes of CO-GHD and concomitant diseases severely impair socioeconomic conditions and impact mortality; only the subgroup of patients with idiopathic GHD conditions was similar to the background population.

Abstract
CONTEXT Estradiol (E(2)) promotes and maintains the female phenotype characterized by subcutaneous fat accumulation. There is evidence to suggest that this effect is due to increased anti-lipolytic α2A-adrenergic receptors, but whether this requires long-term exposure to E(2) or is an immediate effect is not clear. OBJECTIVE To study acute effects of a single dose (4 mg) of 17β-E(2) on regional and systemic lipolysis. METHODS Sixteen postmenopausal women (age, 595 years; weight, 6710 kg; and BMI, 24.82.9) were studied in a crossover design: i) placebo and ii) 4 mg E(2). Basal and adrenaline-stimulated regional lipolysis was assessed by microdialysis and substrate oxidation rates by indirect calorimetry. Tissue biopsies were obtained to assess lipoprotein lipase activity and mRNA expression of adrenergic, estrogen, cytokine, and vascular reactivity receptors. RESULTS Acute E(2) stimulation significantly attenuated catecholamine-stimulated lipolysis in femoral subcutaneous adipose tissue (interstitial glycerol concentration (micromole/liter) ANOVA time vs treatment interaction, P=0.01) and lipolysis in general in abdominal adipose tissue (ANOVA treatment alone, P<0.05). E(2) also reduced basal lipid oxidation ((mg/kg per min) placebo, 0.58 ± 0.06 vs E(2), 0.45 ± 0.03; P=0.03) and induced a significantly higher expression of anti-lipolytic α2A-adrenergic receptor mRNA (P=0.02) in skeletal muscle tissue as well as an upregulation of eNOS (NOS3) mRNA (P=0.02). CONCLUSION E(2) acutely attenuates the lipolytic response to catecholamines in subcutaneous adipose tissue, shifts muscular adrenergic receptor mRNA toward anti-lipolytic α2A-receptors, decreases whole body lipid oxidation, and enhances expression of markers of vascular reactivity.
