Context: Women with hypopituitarism remain at increased risk of morbidity and mortality. Insufficient replacement of sex steroids has been suggested as a contributing factor, but sex steroid levels in women with hypopituitarism have not been comprehensively mapped., Objective: To quantify sex steroids in women with hypopituitarism by a high-sensitivity assay., Methods: Using a combination of clinical and biochemical criteria, women with hypopituitarism (n = 104) who started GH replacement in 1995 to 2014 at a single center were categorized as eugonadal or having hypogonadotropic hypogonadism (HH). A population-based cohort of women (n = 288) served as controls. Eugonadal women and controls were categorized as pre-/postmenopausal and HH women as younger/older (≤ or >52 years). Dehydroepiandrosterone (DHEA), androstenedione, testosterone, dihydrotestosterone, progesterone, 17αOH-progesterone, estradiol, and estrone were analyzed by a validated liquid chromatography-tandem mass spectrometry assay., Results: Among both premenopausal/younger and postmenopausal/older women, women with HH had lower levels of sex steroid precursors (DHEA, androstenedione) and androgens (testosterone and dihydrotestosterone) than controls. Progesterone, 17αOH-progesterone, estrone, and estradiol showed similar patterns. Women with HH and ACTH deficiency had markedly lower concentrations of all sex hormones than those without ACTH deficiency., Conclusion: This study demonstrates for the first time a broad and severe sex steroid deficiency in both younger and older women with HH, particularly in those with combined gonadotropin and ACTH deficiency. The health impact of low sex steroid levels in women with hypopituitarism requires further study, and women with combined gonadotropin and ACTH deficiency should be a prioritized group for intervention studies with sex hormone replacement., (© The Author(s) 2024.

Purpose: To study the long-term effect of transsphenoidal surgery (TSS) on headache in patients with non-functioning pituitary adenoma (NFPA) and identify factors predicting headache relief following TSS., Methods: We evaluated headache in 101 consecutive patients with NFPA who underwent TSS from September 2015 to December 2021, preoperatively and 12-months post-surgery, by using the Migraine Disability Assessment (MIDAS) questionnaire. Health-related quality of life (QoL) was assessed using the EQ-5D visual analogue scale (EQ-VAS)., Results: Of 101 patients, 27 (27%) experienced disabling preoperative headache. Among these, the median total MIDAS score improved from 60 (interquartile range (IQR): 19-140) to 10 (IQR: 0-49) (P = 0.004). Additionally, headache frequency over a 90-day period decreased from 45 (IQR: 25-83) to 6 (IQR: 3-36) days (P = 0.002), and headache intensity decreased from 5 (IQR: 4-7) to 4 (IQR: 2-7) (P = 0.016) at 12-months post-surgery. At 12 months post-surgery, 18 (67%) of 27 patients with preoperatively disabling headache showed clinically relevant improvement of their headache, 4 (15%) showed deterioration, and 5 (19%) remained unchanged. In patients with clinically relevant improvement of their headache, the EQ-VAS score improved from 50 (IQR: 30 - 7) to 80 (IQR: 65-86) (P < 0.001). Of the 74 patients with no preoperative headache, 11 (15%) developed postoperative headache. We identified no clinical factors predicting postoperative headache relief., Conclusion: The study supports that clinically significant and long-lasting improvements of disabling headache and QoL can be achieved with TSS in a substantial number of patients with NFPA., (© 2024.

Various factors may affect cognition in patients with pituitary adenoma, including size and extension of the tumor, degree of pituitary hormone deficiencies, and treatment of the tumor, most often being transsphenoidal surgery (TSS). The aim of this cross-sectional study was to evaluate cognitive function in patients with clinically significant pituitary adenoma and to identify factors influencing cognition. Sixty-eight patients with pituitary adenoma were included. Of these, 31 patients were evaluated before TSS and 37 patients 12 months following TSS. Cognitive function was evaluated by using the Repeatable Battery for the Assessment of Neuropsychological Status. Patients had lower mean scores on cognitive assessment compared to age-adjusted normative data. Variability in cognition, analyzed by linear regression analysis, was explained by sex, educational level, and self-perceived fatigue, but not by pituitary hormone deficiencies, diabetes insipidus, or surgical treatment. Our results are in line with previous findings, namely that pituitary adenoma affects cognition. To better evaluate the factors affecting cognition, longitudinal studies are recommended. Such studies would allow for within-individual comparisons, effectively controlling for the considerable influence of sex and education on test results., Competing Interests: DSO has been a consultant for Novo Nordisk, Sandoz, Ipsen, and Pfizer; has received unrestricted grants from Sandoz and Pfizer; and is an employee of AstraZeneca since 30 August 2021.

Context: There is a lack of reliable biomarkers capable of predicting postoperative tumor progression of nonfunctioning pituitary adenomas (NFPAs)., Objective: To discover proteomic profiles associated with postoperative tumor progression in patients with NFPAs. This was a case-controlled exploratory study at a tertiary university hospital. Tissue samples were obtained from 46 patients with residual tumor following surgery for NFPAs of gonadotroph lineage. Two patient groups were compared: patients requiring reintervention due to residual tumor progression (cases; reintervention group, n = 29) and patients with a residual tumor showing no progression for a minimum of 5 years (controls; radiologically stable group, n = 17). Differentially expressed proteins (DEPs) between patient groups were measured., Results: Global quantitative proteomic analysis identified 4074 proteins, of which 550 were differentially expressed between the 2 groups (fold change >80%, false discovery rate-adjusted P ≤ .05). Principal component analysis showed good separation between the 2 groups. Functional enrichment analysis of the DEPs indicated processes involving translation, ROBO-receptor signaling, energy metabolism, mRNA metabolism, and RNA splicing. Several upregulated proteins in the reintervention group, including SNRPD1, SRSF10, SWAP-70, and PSMB1, are associated with tumor progression in other cancer types., Conclusion: This is the first exploratory study analyzing proteomic profiles as markers of postoperative tumor progression in NFPAs. The findings clearly showed different profiles between tumors with indolent postoperative behavior and those with postoperative tumor progression. Both enriched pathways involving DEPs and specific upregulated proteins have previously been associated with tumor aggressiveness. These results suggest the value of proteomic profiling for predicting tumor progression in patients with NFPAs., (© The Author(s) 2023.

Purpose: The aim of this study was to establish a valid national cohort of patients diagnosed with acromegaly by combining data from the general National Patient Register (NPR) and the disease-specific Swedish Pituitary Register (SPR)., Methods: Patients ≥ 18 years of age at diagnosis of acromegaly reported from 1991 to 2018 who were registered in the NPR and/or SPR were included. The diagnosis of acromegaly was considered correct for patients identified in both registers or confirmed through chart review. Medical records were reviewed in two of Sweden´s six health care regions if the patient was reported only in the NPR. An algorithm for the NPR, with criteria requiring multiple diagnosis registrations and tumour and/or surgery codes, was constructed to reduce the number of patients to review in the remaining four regions., Results: A total of 1866 patients were identified. Among these, 938 were reported in both registers. After application of the algorithm and chart review, the diagnosis was confirmed for 83 of the 906 patients found only in the NPR. Among 22 patients only registered in the SPR, a review of medical records confirmed acromegaly in 13. This resulted in a total of 1034 cases with acromegaly during the study period. The incidence rate of acromegaly in Sweden 1991-2018 was calculated to 4.0/million/year in the entire population and 5.1/million/year among subjects ≥ 18 years of age., Conclusion: The combination of the SPR and NPR established a valid cohort of patients diagnosed with acromegaly and increased the estimated incidence in Sweden., (© 2023.

Background: Patients with adrenal insufficiency (AI) have excess morbidity and mortality related to infectious disorders. Whether patients with AI have increased morbidity and mortality from COVID-19 is unknown., Methods: In this linked Swedish national register-based cohort study, patients with primary and secondary AI diagnosis were identified and followed from 1 January 2020 to 28 February 2021. They were compared with a control cohort from the general population matched 10:1 for age and sex. The following COVID-19 outcomes were studied: incidence of COVID-19 infection, rates of hospitalization, intensive care admission and death. Hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for socioeconomic factors and comorbidities were estimated using Cox regression analysis., Results: We identified 5430 patients with AI and 54,300 matched controls: There were 47.6% women, mean age was 57.1 (standard deviation 18.1) years, and the frequency of COVID-19 infection was similar, but the frequency of hospitalization (2.1% vs. 0.8%), intensive care (0.3% vs. 0.1%) and death (0.8% vs. 0.2%) for COVID-19 was higher in AI patients than matched controls. After adjustment for socioeconomic factors and comorbidities, the HR (95% CI) was increased for hospitalization (1.96, 1.59-2.43), intensive care admission (2.76, 1.49-5.09) and death (2.29, 1.60-3.28)., Conclusion: Patients with AI have a similar incidence of COVID-19 infection to a matched control population, but a more than twofold increased risk of developing a severe infection or a fatal outcome. They should therefore be prioritized for vaccination, antiviral therapy and other appropriate treatment to mitigate hospitalization and death., (© 2023 The Authors.

Background: Primary aldosteronism (PA) is associated with increased mortality. The extent to which this phenomenon is affected by sex, age, comorbidities at diagnosis, and different treatment modalities is largely unknown. The objective was to determine all-cause and cause-specific mortality in a population-based cohort of patients with PA and the impact of age at diagnosis, sex, comorbidities, and treatment modalities., Methods: We used national registers to identify patients diagnosed with PA between 1997 and 2019 (n=2419) and controls (n=24 187) from the general population, matched for sex, age, and county of residence. We obtained mortality data from the Cause-of-Death Register. We used Cox regression models, adjusted for socioeconomic factors and diabetes, to estimate adjusted hazard ratios (HRs [95% CI])., Results: Overall, 346 (14.3%) patients with PA and 2736 (11.3%) controls died during a median follow-up time of 8.1 years. PA was associated with increased risk from all-cause mortality (HR, 1.23 [95% CI, 1.10-1.38]), death from cardiovascular disease (HR, 1.57 [95% CI, 1.30-1.89]), and stroke (HR, 1.85 [95% CI, 1.16-2.93]). Patients with cardiovascular disease at diagnosis (HR, 1.53 [1.26-1.85]), age >56 years (HR, 1.28 [95% CI, 1.13-1.45]), patients treated with a low dose of a mineralocorticoid receptor antagonist (HR, 1.30 [95% CI, 1.02-1.66]), and untreated patients (HR, 2.51 [95% CI, 1.72-3.67]) had excess mortality., Conclusions: Mortality, mainly due to cardiovascular disease, is increased in patients with PA compared with controls from the general population, particularly in patients aged >56 years, patients with preexisting cardiovascular comorbidities, and patients receiving low dose of a mineralocorticoid receptor antagonist., Competing Interests: Disclosures D.S.

Growth hormone (GH) deficiency (GHD) is one of the most prevalent deficiencies in patients with hypopituitarism and several cohort studies have demonstrated an increased mortality risk in hypopituitary patients with a presumed GHD. The cause of the excess mortality is most likely multifactorial, including the etiology of the hypopituitarism, non-physiological replacement therapies (mostly glucocorticoid), tumor treatment and its side effects as well as untreated GHD. Several years later, other cohort studies that investigated life expectancy in patients with hypopituitarism on GH replacement therapy (GHRT) that showed a normalized mortality. By comparison of the distribution of characteristics of interest between cohorts, we discuss the existing literature to answer the following question: does growth hormone replacement really improve mortality rates in adult patients with hypopituitarism and GHD? We also conducted a meta-analysis of these studies. Since the literature suffers from selection and time bias (improvement of tumor management and other pituitary hormone replacement therapies), there is no high-quality evidence that replacement therapy for GHD really improves mortality. However, the available data does suggest that GHRT plays a significant part in the normalization of the mortality in patients with hypopituitarism., Competing Interests: Declaration of Competing Interest DSO has served as a consultant for Ipsen, Pfizer, NovoNordisk, and Sandoz; has received research grants from Sandoz and Pfizer; and is an employee at AstraZeneca as of 30 August 2021.

Purpose: To describe the clinical presentation and treatment outcomes in a nationwide cohort of patients with giant prolactinomas., Methods: Register-based study of patients with giant prolactinomas [serum prolactin (PRL) > 1000 µg/L, tumor diameter ≥40 mm] identified in the Swedish Pituitary Register 1991-2018., Results: Eighty-four patients [mean age 47 (SD ±16) years, 89% men] were included in the study. At diagnosis, the median PRL was 6305 µg/L (range 1450-253 000), the median tumor diameter was 47 mm (range 40-85), 84% of the patients had hypogonadotropic hypogonadism, and 71% visual field defects. All patients were treated with a dopamine agonist (DA) at some point. Twenty-three (27%) received 1 or more additional therapies, including surgery (n = 19), radiotherapy (n = 6), other medical treatments (n = 4), and chemotherapy (n = 2). Ki-67 was ≥10% in 4/14 tumors. At the last follow-up [median 9 years (interquartile range (IQR) 4-15)], the median PRL was 12 µg/L (IQR 4-126), and the median tumor diameter was 22 mm (IQR 3-40). Normalized PRL was achieved in 55%, significant tumor reduction in 69%, and combined response (normalized PRL and significant tumor reduction) in 43%. In the primary DA-treated patients (n = 79), the reduction in PRL or tumor size after the first year predicted the combined response at the last follow-up (P < .001 and P = .012, respectively)., Conclusion: DAs effectively reduced PRL and tumor size, but approximately 1 patient out of 4 needed multimodal treatment. Our results suggest that the response to DA after 1 year is useful for identifying patients who need more careful monitoring and, in some cases, additional treatment., (© The Author(s) 2023.

Background: Patients undergoing pituitary surgery may experience short- and long-term postoperative morbidity. Intraoperative factors such as hypotension might be a contributing factor. Our aim was to investigate the association between intraoperative hypotension and postoperative plasma levels of tau, neurofilament light (NfL), and glial fibrillary acidic protein (GFAP) as markers of perioperative brain injury., Methods: Between June 2016 and October 2017, 35 patients from the Gothenburg Pituitary Tumor Study were included. For tau, NfL, and GFAP, concentrations were measured in plasma samples collected before and immediately following surgery, and on postoperative days 1 and 5. The difference between the highest postoperative value and the value before surgery was used for analysis (∆tau peak , ∆NfL peak , ∆GFAP peak ). Intraoperative hypotension was defined as the area under the curve of an absolute threshold below 70 mmHg (AUC70) and a relative threshold below 20% (AUC20%) of the baseline mean arterial blood pressure., Results: Plasma tau and GFAP were highest immediately following surgery and on day 1, while NfL was highest on day 5. There was a positive correlation between AUC20% and both ∆tau peak (r 2  = .20, p < .001) and ∆NfL peak (r 2  = .26, p < .001). No association was found between AUC20% and GFAP or between AUC70 and ∆tau peak , ∆NfL peak or ∆GFAP peak ., Conclusion: Intraoperative relative, but not absolute, hypotension was associated with increased postoperative plasma tau and NfL concentrations. Patients undergoing pituitary surgery may be vulnerable to relative hypotension, but this needs to be validated in future prospective studies., (© 2023 The Authors.

Objective: Data on pre- and postoperative pituitary function in nonfunctioning pituitary adenomas (NFPA) are not consistent. We aimed to investigate pituitary function before and up to 5 years after transsphenoidal surgery with emphasis on the hypothalamic-pituitary-adrenal axis (HPA)., Design and Methods: Data from the Swedish Pituitary Register was used to analyze anterior pituitary function in 838 patients with NFPA diagnosed between 1991 and 2014. Patients who were reoperated or had received radiotherapy were excluded., Results: Preoperative ACTH, TSH, LH/FSH, and GH deficiencies were reported in 31% (236/755), 39% (300/769), 51% (378/742), and 28% (170/604) of the patients, respectively. Preoperative median tumor volume was 5.0 (2.4-9.0) cm3. Among patients with preoperative, 1 year and 5 years postoperative data on the HPA axis (n = 428), 125 (29%) were ACTH-deficient preoperatively. One year postoperatively, 26% (32/125) of them had recovered ACTH function while 23% (70/303) patients had developed new ACTH deficiency. Thus, 1 year postoperatively, 163 (38%) patients were ACTH-deficient (P < .001 vs. preoperatively). No further increase was seen 5 years postoperatively (36%, P = .096). At 1 year postoperatively, recoveries in the TSH and LH/FSH axes were reported in 14% (33/241) and 15% (46/310), respectively, and new deficiencies in 22% (88/403) and 29% (83/288), respectively., Conclusions: Adrenocorticotrophic hormone deficiency increased significantly at 1 year postoperatively. Even though not significant, some patients recovered from or developed new deficiency between 1 and 5 years postoperatively. This pattern was seen in all axes. Our study emphasizes that continuous individual evaluations are needed during longer follow-up of patients operated for NFPA., (© The Author(s) 2023.

Objective: Pituitary adenomas and their consequences impact mortality and morbidity. We studied the healthcare costs, survival, and cost-effectiveness of growth hormone (GH) vs no GH replacement in patients with non-functioning pituitary adenoma (NFPA)., Design and Methods: A cohort study including all NFPA patients followed from 1987 or the date of diagnosis until the time of death or December 31, 2019, in the Västra Götaland region, Sweden. Data to assess resource use, costs, survival, and cost-effectiveness were collected from patient records and regional/national healthcare registries., Results: A total of 426 patients with NFPA (274 men) with a follow-up of 13.6 ± 6.8 years (mean ± SD) were included. The total annual healthcare cost was higher in patients receiving GH (€9287) than those without GH (€6770), mainly driven by a higher pharmaceutical cost. Glucocorticoid replacement therapy (P = .02), diabetes insipidus (P = .04), body mass index (BMI) (P < .01), and hypertension (P < .01) were all individually associated with a higher total annual cost. The survival rate was higher in the GH group (HR [hazard ratio] 0.60; P = .01) and reduced in patients with glucocorticoid replacement (HR 2.02; P < .01) or diabetes insipidus (HR 1.67; P = .04). The cost per gained life-year for GH vs no GH replacement was about €37 000., Conclusions: This healthcare utilization study identified several factors driving the cost of care in NFPA patients, such as GH replacement, adrenal insufficiency, and diabetes insipidus. Life expectancy was increased in those with GH replacement and reduced in patients with adrenal insufficiency and diabetes insipidus., Competing Interests: Conflicts of interest: D.S.O. has been a consultant for Sandoz, Ipsen, and Pfizer; has received unrestricted grants from Sandoz and Pfizer; and is an employee at AstraZeneca as of August 8, 2021.

Introduction: Despite surgical treatment, pituitary adenomas often cause long-term illness symptoms, that profoundly impact patients' quality of life physically, psychologically and socially. Healthcare professionals often fail to recognize and discuss the ensuing problems. Personal documentation, such as symptom monitoring, reflective writing or even posts on social media, may help this patient group to manage their daily life and support communication of their care needs. Documentation strategies and the role of documentation for people with long-term symptoms after pituitary adenoma surgery are currently unknown., Aim: To examine the effects and strategies of documenting symptoms, activities and physical and emotional well-being among people living with long-term pituitary adenoma., Methods: In this Constructivist Grounded Theory study, 12 individuals living with long-term illness symptoms after pituitary adenoma surgery described their documentation strategies in in-depth interviews using teleconferencing and photo-elicitation between August and October 2020., Results: Strategies for documentation included analogue and digital media. One core category (Exercising autonomy) and three categories describing processes (Gaining insight, Striving for control and Sharing) emerged from the analysis. These three interrelated processes become an expression of autonomy to manage life and make sense of chronic illness. Personal documentation is a flexible tool that is used more extensively in times of ill health and less in times of relative well-being. Sharing documentation with healthcare professionals facilitated care planning and sharing with friends and family fostered emotional well-being., Conclusion: Personal documentation is a valuable resource for managing life after pituitary adenoma surgery. The current findings may be relevant to other chronic illnesses. Further research exploring potential tools for personal documentation is needed., Patient or Public Contribution: We deliberately chose a Constructivist Grounded Theory approach for this interview study. Using Constructivist Grounded Theory, we gave people living with long-term symptoms a voice, allowing them to freely speak about managing their illness in connection with personal documentation. The theoretical sampling approach enabled us to invite participants that could provide a broad overview of the landscape of personal documentation., (© 2022 The Authors.

Background: Childhood cancer survivors are at risk of developing skeletal comorbidities later in life. We aimed to assess risk factors for low and very low bone mineral density (BMD), and the risk of and risk factors for any fractures and vertebral fractures in a national cohort of Dutch adult childhood cancer survivors., Methods: In this cross-sectional study, we used data from the DCCSS LATER cohort, which comprised individuals who were alive for at least 5 years after diagnosis of childhood cancer (ie, histologically confirmed malignancies or Langerhans cell histiocytosis), were diagnosed before the age of 19 years, and who had been treated at one of seven Dutch paediatric oncology centres between 1963 and 2002 (hereafter referred to as survivors). For this study, we invited survivors aged 18-45 years, who were alive as of Oct 10, 2016, living in the Netherlands, and who were deemed eligible by their treating physician to participate. We assessed BMD using dual-energy x-ray absorptiometry (DXA). Self-reported fractures that occurred at least 5 years after cancer diagnosis were assessed using available medical history and compared with population-level data from the Swedish national registry. We assessed vertebral fractures in a subset of participants using a vertebral fracture assessment. We assessed associations between the occurrence of low (Z-score of ≤-1) or very low (Z-score of ≤-2) BMD, fractures, and vertebral fractures and demographic, treatment-related, endocrine, and lifestyle-related factors using logistic regression analysis., Findings: Between April 29, 2016, and Jan 22, 2020, 3996 (64·8%) of 6165 individuals from the DCCSS LATER cohort were invited to participate, of whom 2003 (50·1%) were enrolled (mean age at participation was 33·1 years [SD 7·2], 966 [48·2%] were female, and 1037 [51·8%] were male [data on ethnicity and race were not available due to national policies]). 1548 (77·3%) had evaluable DXA scans for assessment of BMD, 1892 (94·5%) provided medical history of fractures, and 249 (12·4%) were assessed for vertebral fractures. 559 (36·1%) of 1548 had low BMD at any site, and 149 (9·6%) had very low BMD at any site. The standardised incidence ratio of any first fracture was 3·53 (95% CI 3·06-4·06) for male participants and 5·35 (4·46-6·52) for female participants. 33 (13·3%) of 249 participants had vertebral fractures. Male sex, underweight, high carboplatin dose, any dose of cranial radiotherapy, hypogonadism, hyperthyroidism, low physical activity, and severe vitamin D deficiency were associated with low BMD at any site and male sex, underweight, cranial radiotherapy, growth hormone deficiency, and severe vitamin D deficiency were associated with very low BMD at any site. Additionally, male sex, former and current smoking, and very low lumbar spine BMD were associated with any fractures, whereas older age at follow-up, previous treatment with platinum compounds, growth hormone deficiency, and low physical activity were specifically associated with vertebral fractures., Interpretation: Survivors of childhood cancer are at increased risk of any first fracture. Very low lumbar spine BMD was associated with fractures, highlighting the importance of active BMD surveillance in high-risk survivors (ie, those treated with cranial, craniospinal, or total body irradiation). Moreover, our results indicate that intensive surveillance and timely interventions for endocrine disorders and vitamin deficiencies might improve bone health in childhood cancer survivors, but this needs to be assessed in future studies., Funding: Children Cancer-free Foundation (KiKa), KiKaRoW, and ODAS foundation., Competing Interests: Declaration of interests IH declares institutional contracts from Abbott, Siemens Healthineers, and Beckman Coulter.

Importance: Acute lymphoblastic leukemia (ALL) constitutes 20% to 30% of all pediatric cancers. The 5-year overall survival among pediatric patients with ALL in high-income countries such as Sweden is currently more than 90%, but long-term unselected nationwide mortality data and mortality data in relation to the general population are lacking., Objective: To compare mortality between pediatric patients with ALL and the general population during a 30-year period in Sweden and to assess the incidence of ALL in Sweden., Design, Setting, and Participants: This cohort study included pediatric patients (aged <18 years) with a morphologically verified ALL diagnosis in the Swedish Cancer Register and/or at least 2 ALL diagnoses in the Swedish National Patient Register between January 1, 1988, and December 31, 2017. Data were cross-linked to the Swedish Cause of Death Register. Data were analyzed from May 2019 to January 2022., Main Outcomes and Measures: The main outcomes were mortality among patients with ALL compared with that in the general population and mortality in different subgroups within the cohort. Standardized mortality ratios (SMRs) were calculated using the general Swedish population as a reference. Within-cohort survival analyses were performed., Results: A total of 2397 patients (1354 [56%] male; mean [SD] age at diagnosis, 6.1 [4.7] years) were included in the study. The mean (SD) incidence of pediatric ALL during the study period was 4.11 (0.60) cases per 100 000 persons per year (females, 3.68 [0.65] cases per 100 000 persons per year; males, 4.52 [0.81] cases per 100 000 persons per year; P < .001). The observed number of deaths among pediatric patients with ALL was 409 vs the 9.5 deaths expected in the general population, resulting in an overall SMR of 43.1 (95% CI, 39.0-47.5); females had a higher SMR than males (57.8 [95% CI, 49.5-67.2] vs 34.5 [95% CI, 32.0-41.4]; P < .001). Analysis within the cohort showed a continued decrease in survival throughout the 30-year follow-up. The association between calendar year of ALL diagnosis, corresponding with different ALL treatment protocols, and mortality showed the lowest survival for the 1988-1991 group and the highest for the 2008-2017 group (χ2 = 20.3; P < .001)., Conclusions and Relevance: In this cohort study, a consistently high SMR was seen among pediatric patients with ALL. Within the ALL cohort, survival evolved to a similar extent as in the young general population of Sweden. Furthermore, survival among patients with ALL decreased throughout the whole follow-up period without any trend difference after the 5-year follow-up time point. The changes in ALL treatment protocols were associated with overall improved absolute survival over time.

Context: Diabetes is a major risk factor for cardiovascular disease and death but its effect on outcomes in acromegaly is unknown., Objective: This work aimed to study whether diabetes affects morbidity and mortality in patients with acromegaly., Methods: A nationwide (Sweden), observational, matched-cohort study was conducted. Patients diagnosed with acromegaly between 1987 and 2020 were identified in the Swedish National Patient Registry and those with concomitant type 2 diabetes in the National Diabetes Registry and Drug Registry. The risk of overall mortality, and cardiovascular mortality and morbidity were estimated using Cox regression., Results: The study included 254 patients with acromegaly and concomitant type 2 diabetes (ACRO-DM group) and 532 without diabetes (ACRO group). Mean (SD) age at baseline was 62.6 (11.4) and 60.0 (12.1) years (P = .004) and the mean (SD) duration of acromegaly was 6.8 (8.1) and 6.0 (6.2) years (P = .098) in the ACRO-DM and ACRO groups, respectively. Overall mean follow-up was 9.2 years. The unadjusted overall mortality rate per 1000 person-years was 35.1 (95% CI, 27.2-44.7) and 20.1 (95% CI, 16.5-24.3) in the respective groups. The hazard ratio (HR) for overall mortality adjusted for multiple confounders was 1.58 (95% CI, 1.12-2.23) in the ACRO-DM group compared with the ACRO group. Cardiovascular mortality (HR 2.11; 95% CI, 1.09-4.10) and morbidity (HR 1.49; 95% CI, 1.21-1.82) were also increased in the ACRO-DM group., Conclusion: The presence of diabetes in patients with acromegaly was associated with increased overall mortality as well as increased cardiovascular mortality and morbidity., (© The Author(s) 2022.

Context: Tumor progression in surgically treated patients with nonfunctioning pituitary adenomas (NFPAs) is associated with excess mortality. Reliable biomarkers allowing early identification of tumor progression are missing., Objective: To explore DNA methylation patterns associated with tumor progression in NFPA patients., Methods: This case-controlled exploratory trial at a university hospital studied patients who underwent surgery for NFPA that had immunohistochemical characteristics of a gonadotropinoma. Cases included patients requiring reintervention due to tumor progression (reintervention group, n = 26) and controls who had a postoperative residual tumor without tumor progression for at least 5 years (radiologically stable group, n = 17). Genome-wide methylation data from each tumor sample were analyzed using the Infinium MethylationEPIC BeadChip platform., Results: The analysis showed that 605 CpG positions were significantly differently methylated (differently methylated positions, DMPs) between the patient groups (false discovery rate adjusted P value < 0.05, beta value > 0.2), mapping to 389 genes. The largest number of DMPs were detected in the genes NUP93 and LGALS1. The 3 hypomethylated DMPs and the 3 hypermethylated DMPs with the lowest P values were all significantly (P < 0.05) and individually associated with reintervention-free survival. One of the hypermethylated DMPs with the lowest P value was located in the gene GABRA1., Conclusion: In this exploratory study, DNA methylation patterns in NFPA patients were associated with postoperative tumor progression requiring reintervention. The DMPs included genes that have been previously associated with tumor development. Our study is a step toward finding epigenetic signatures to predict tumor progression in patients with NFPA., (© The Author(s) 2022.

Objective: The aim of the study was to investigate all-cause and disease-specific mortality in a large population-based cohort of oral glucocorticoid (GC) users., Methods: This was a retrospective, matched cohort study. Information on dispensed prescriptions was obtained from the Swedish Prescribed Drug Register. The cause of death was obtained from the Swedish Cause-of-Death Registry. Patients receiving prednisolone ≥5 mg/day (or equivalent dose of other GC) for ≥21 days between 2007-2014 were included. For each patient, one control subject matched for age and sex was included. The study period was divided into 3-month periods and patients were divided into groups according to a defined daily dose (DDD) of GC used per day. The groups were: Non-users (0 DDD per day), low-dose users (>0 but <0.5 DDD per day), medium-dose users (0.5-1.5 DDD per day) and high-dose users (>1.5 DDD per day). Hazard ratios (HRs), unadjusted and adjusted for age, sex and comorbidities, were calculated using a time-dependent Cox proportional hazard model., Results: Cases (n=223 211) had significantly higher all-cause mortality compared to controls (HR adjusted for age, sex and comorbidities 2.08, 95% confidence interval 2.04 to 2.13). After dividing the cases into subgroups, adjusted HR was 1.31 (1.28 to 1.34) in non-users, 3.64 (3.51 to 3.77) in low-dose users, 5.43 (5.27 to 5.60) in medium-dose users and, 5.12 (4.84 to 5.42) in high-dose users. The highest adjusted hazard ratio was observed in high-dose users for deaths from sepsis 6.71 (5.12 to 8.81) and pulmonary embolism 7.83 (5.71 to 10.74)., Conclusion: Oral GC users have an increased mortality rate compared to the background population, even after adjustment for comorbidities. High-dose users have an increased risk of dying from sepsis, and pulmonary embolism compared to controls. Whether the relationship between GC exposure and the excess mortality is causal remains to be elucidated., Competing Interests: DO has received consultant fees from Pfizer, Sandoz, Ipsen and NovoNordisk.

The co-creation and sharing of documentation of person-centered care is important, but challenging in clinical practice. Online access to health records is considered essential to increase patient participation and empowerment in person-centered care provision. The aims of this study were (1) to identify the extent of person-centered content in medical inpatient records and discharge letters; (2) to describe the characteristics of the language and rhetoric used in discharge letters. This was a concurrent, mixed-methods study involving a deductive, quantitative analysis of person-centered content in 69 Patient Accessible Electronic Health Records from patients with pituitary tumors, and an iterative, qualitative language analysis of a nested sample of 57 discharge letters. Both the content and language of inpatient records were mostly patient-centered. Records were concerned with the documentation of symptoms and medical and care interventions. There was little person-centered documentation of patients' preferences, wishes and needs, and shared decision-making. In the discharge letters, written for the patients, some physicians had attempted to write in a person-centered way, using plain language and a narrative. However, most wrote in a style that was reflective of their discourse community, using abbreviations and medical terms. Established norms for documentation in healthcare are a barrier to person-centered documentation. Patients' needs and preferences about documentation should be explored to increase understanding of how person-centered documentation can be achieved in clinical practice.

Background: The use of firefighting foams at a military airport resulted in high levels of perfluorinated substances (PFAS) in the drinking water distributed to one-third of households in the Swedish municipality of Ronneby between the mid-1980s and the end of 2013., Method: The Ronneby Register Cohort, a large cohort comprising all individuals (N = 60,507) who ever lived in the Ronneby municipality during the period of drinking water contamination, was linked to the Swedish Cancer Register 1985-2016. Individual exposure was classified based on comprehensive data on yearly residential address and water distribution. External analysis explored standardized cancer incidence ratios (SIR) for residents never, or ever, residing in the contaminated water district, compared with those residing in other towns in the same county as reference population. Cox models provided hazard ratios (HR) for different exposure groups within the cohort., Results: 5,702 individuals with cancer were identified. SIR for overall cancer was 1.04 for men (95%CI 0.96-1.12) and 0.89 for women (95%CI 0.82-0.96) who ever lived in the contaminated drinking water area. Kidney cancer, which was reported with increased risk in C8 study, showed somewhat elevated HR in this study (HR 1.27; 95%CI 0.85-1.89). The HR was modestly elevated for bladder cancer (HR 1.32; 95%CI 1.01-1.72), and reduced for prostate cancer (HR 0.83; 95%CI 0.71-0.98). In subjects who ever lived in the contaminated water area during 2005-2013, when exposure was estimated to be highest, higher risks for kidney cancer (HR 1.84; 95%CI 1.00-3.37) but lower for prostate cancer (HR 0.76; 95%CI 0.59-0.98) were observed., Conclusion: Analysis of this large cohort exposed to high levels of PFAS, dominated by PFHxS and PFOS, revealed no evidence for an overall increased risk of cancer. A moderately increased risk of kidney cancer was observed, in accordance with previous findings after PFAS exposure dominated by PFOA., (Copyright © 2021 The Authors. Published by Elsevier Inc.

Context: Whether cancer risk in acromegaly is increased remains controversial, and the risk of benign tumors has been little studied., Objective: To investigate the incidence of benign and malignant tumors in acromegaly in a nationwide population-based study., Methods: Adult patients diagnosed with acromegaly between 1987 and 2017 were identified in the Swedish National Patient Registry. The diagnoses of benign and malignant tumors were recorded. Standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) for neoplasms with 95% CIs were calculated using the Swedish general population as reference., Results: The study included 1296 patients (52% women). Mean (SD) age at diagnosis was 51.6 (14.7) years. Median (range) follow-up time was 11.7 (0-31) years. Overall, 186 malignancies were identified in acromegalic patients compared with 144 expected in the general population (SIR 1.3; 95% CI 1.1-1.5). The incidence of colorectal and anal cancer (SIR 1.5; 95% CI 1.0-2.2), and renal and ureteral cancer (SIR 4.0; 95% CI 2.3-6.5) was increased, whereas the incidence of malignancies of the respiratory system, brain, prostate, and breast was not. Only 3 cases of thyroid cancer were recorded. Mortality due to malignancies was not increased (SMR 1.1; 95% CI 0.9-1.4). Incidence of benign tumors was increased more than 2-fold (SIR 2.4; 95% CI 2.1-2.7)., Conclusion: Patients with acromegaly had an increased risk of both benign and malignant tumors, including colorectal and anal cancer, and renal and ureteral cancer. Whether this is associated with acromegaly itself or due to more intensive medical surveillance remains to be shown., (© The Author(s) 2021.

Context: Craniopharyngioma is a sellar tumor associated with high rates of pituitary deficiencies (~ 98%) and hypothalamic obesity (~ 50%)., Objective: This work aims to determine the efficacy regarding long-term weight loss after bariatric surgery in obese craniopharyngioma patients with hypothalamic dysfunction., Methods: This retrospective, case-control, multicenter, international study included obese craniopharyngioma patients (N = 16; of whom 12 are women) with a history of bariatric surgery (12 Roux-en-Y gastric bypass, 4 sleeve gastrectomy; median age 21 years [range, 15-52 years], median follow-up 5.2 years [range, 2.0-11.3 years]) and age/sex/surgery/body mass index-matched obese controls (N = 155). Weight loss and obesity-related comorbidities up to 5 years after bariatric surgery were compared and changes in hormonal replacement therapy evaluated., Results: Mean weight loss at 5-year follow-up was 22.0% (95% CI, 16.1%-27.8%) in patients vs 29.5% (95% CI, 28.0%-30.9%) in controls (P = .02), which was less after Roux-en-Y gastric bypass (22.7% [16.9%-28.5%] vs 32.0% [30.4%-33.6%]; P = .003) but at a similar level after sleeve gastrectomy (21.7% [-1.8% to 45.2%] vs 21.8% [18.2%-25.5%]; P = .96). No major changes in endocrine replacement therapy were observed after surgery. One patient died (unknown cause). One patient had long-term absorptive problems., Conclusion: Obese patients with craniopharyngioma had a substantial mean weight loss of 22% at 5-year follow-up after bariatric surgery, independent of type of bariatric surgery procedure. Weight loss was lower than in obese controls after Roux-en-Y gastric bypass. Bariatric surgery appears to be effective and relatively safe in the treatment of obese craniopharyngioma patients., (© The Author(s) 2021.

Purpose: Bilateral adrenalectomy (BA) still plays an important role in the management of Cushing's disease (CD). Nelson's syndrome (NS) is a severe complication of BA, but conflicting data on its prevalence and predicting factors have been reported. The aim of this study was to determine the prevalence of NS, and identify factors associated with its development., Data Sources: Systematic literature search in four databases., Study Selection: Observational studies reporting the prevalence of NS after BA in adult patients with CD., Data Extraction: Data extraction and risk of bias assessment were performed by three independent investigators., Data Synthesis: Thirty-six studies, with a total of 1316 CD patients treated with BA, were included for the primary outcome. Pooled prevalence of NS was 26% (95% CI 22-31%), with moderate to high heterogeneity (I 2 67%, P < 0.01). The time from BA to NS varied from 2 months to 39 years. The prevalence of NS in the most recently published studies, where magnet resonance imaging was used, was 38% (95% CI 27-50%). The prevalence of treatment for NS was 21% (95% CI 18-26%). Relative risk for NS was not significantly affected by prior pituitary radiotherapy [0.9 (95% CI 0.5-1.6)] or pituitary surgery [0.6 (95% CI 0.4-1.0)]., Conclusions: Every fourth patient with CD treated with BA develops NS, and every fifth patient requires pituitary-specific treatment. The risk of NS may persist for up to four decades after BA. Life-long follow-up is essential for early detection and adequate treatment of NS., (© 2021. The Author(s).)

Context: Primary aldosteronism (PA) is the most common cause of secondary hypertension. Yet, the incidence of PA in the general population has not been studied., Objective: To estimate the incidence of PA in the general population., Design and Methods: Patients who had received a diagnostic code for PA between 1987 and 2016 were identified in the Swedish National Patient Registry. Assessment of clinical and biochemical data was used to validate the diagnosis. The annual incidence of PA was calculated by using the number of inhabitants in the Västra Götaland County as a reference., Results: Of 570 identified patients, 473 (83%) had confirmed PA. Eligible for the incidence analysis were 416 patients, 248 (60%) men and 168 (40%) women, diagnosed with PA between 1987 and 2016. The mean (± standard deviation) age at diagnosis was 56 ± 12 years. The median (interquartile range) annual incidence was 2 (1-2) cases per million between 1987 and 1996, 6 (4-9) cases per million between 1997 and 2006 and 17 (12-24) cases per million between 2007 and 2016. At the end of the study (December 31, 2016), 386 patients with confirmed PA were alive and living in the Västra Götaland County, giving a prevalence of 231 cases per million (0.022%)., Conclusions: Despite increasing incidence, the proportion of patients identified with PA is lower than expected. Given the serious consequences of untreated PA, the noticeably low prevalence at the end of the study stresses the need to increase the awareness of PA among health care providers., (© The Author(s) 2021.

Pituitary tumors and subsequent treatment with endoscopic transsphenoidal surgery (ETSS) may cause injury to suprasellar structures, causing long-term fatigue and neurocognitive impairment. A method to quantify brain injury after ETSS is not available. In this prospective, exploratory study of patients undergoing ETSS for pituitary tumors, a novel approach to detect possible neuronal damage is presented. Plasma concentrations of brain injury biomarkers (glial fibrillary acidic protein [GFAP], tau, and neurofilament light [NFL]) were measured the day before surgery, immediately after surgery, at day 1 and 5, and at 6 and 12 months after surgery, using enzyme-linked immunosorbent assays. The association between the increase of biomarkers with preoperative tumor extension and postoperative patient-perceived fatigue was evaluated. Suprasellar tumor extension was assessed from MRI scans, and self-perceived fatigue was assessed using the Multidimensional Fatigue Inventory before and 6 months after surgery. Thirty-five patients were included in the analysis. Compared to baseline, GFAP showed a maximal increase at day 1 after surgery (p = 0.0005), tau peaked postoperatively on the day of surgery (p = 0.019), and NFL reached its maximum at day 5 after surgery (p < 0.0001). The increase in GFAP correlated with preoperative chiasmal compression (p = 0.020). The increase in tau was correlated with preoperative chiasmal (p = 0.011) and hypothalamus compression (p = 0.016), and fatigue score 6 months after surgery (p = 0.016). In conclusion, the concentrations of brain injury biomarkers in blood increased after ETSS for pituitary tumors. The results indicate that postoperative plasma GFAP and tau might reflect astroglial and neuronal damage after ETSS., Competing Interests: Declaration of Competing Interest T S has received lecture fees from Abbott.

Objective  Headache is a common symptom among patients with pituitary tumors, as it is in the general population. The aim of the study was to investigate headache as a symptom in patients with pituitary tumors before and 6 months after endoscopic transsphenoidal surgery (TSS). Design  This is a prospective observational cohort study. Setting  This study was conducted at university tertiary referral hospital. Participants  A total of 110 adult patients underwent endoscopic TSS for pituitary tumors. Main Outcome Measures  The Migraine Disability Assessment (MIDAS) questionnaire was used before and 6 months after surgery for the assessment of headache. Clinical variables with potential influence on headache were analyzed. Results  Sixty-eight (62%) patients experienced headaches at least once during the 3 months before surgery. Thirty (27%) patients reported disabling headache before surgery, with younger age being an independent associated factor ( p  < 0.001). In patients with disabling headache before surgery, the median (interquartile range) MIDAS score improved from 78 (27-168) to 16 (2-145; p  = 0.049), headache frequency decreased from 45 (20-81) to 14 (4-35) days ( p  = 0.009), and headache intensity decreased from 6 (5-8) to 5 (4-7) ( p  = 0.011) after surgery. In total, 16 of the 30 (53%) patients reported a clinically relevant improvement and five (17%) a clinically relevant worsening. Four (5%) patients developed new disabling headache. No predictor for postoperative improvement of headache was identified. Conclusion  In this prospective study, the results show that disabling headache improves following endoscopic TSS in a subset of patients with pituitary tumors. However, no predictive factors for improvement could be identified., Competing Interests: Conflict of Interest T.S. has received lecture fees from Abbott.

Objective: Current markers predicting tumour progression of pituitary adenomas after surgery are insufficient. Our objective was to investigate if minichromosome maintenance protein 7 (MCM7) expression predicts tumour progression in non-functioning pituitary adenomas (NFPAs)., Methods: In a cohort study of surgically treated NFPAs, two groups with distinctly different behaviour of a residual tumour were selected: one group requiring reintervention due to tumour progression (reintervention group, n = 57) and one with residual tumours without progression (radiologically stable group, n = 40). MCM7, Ki-67, oestrogen receptor-α expression, mitotic index and tumour subtype were assessed by immunohistochemistry, and their association with tumour progression requiring reintervention was analysed., Results: Median (IQR) MCM7 expression was 7.4% (2.4-15.2) in the reintervention group compared with 2.0% (0.6-5.3) in the radiologically stable group (P <0.0001). Cox regression analysis showed an association between high (>13%) MCM7 expression and reintervention (HR: 3.1; 95% CI:1.7-5.4; P = 0.00012). The probability for reintervention within 6 years for patients with high MCM7 was 93%. Ki-67 expression >3% (P = 0.00062), age ≤55 years (P = 0.00034) and mitotic index≥1 (P = 0.024) were also associated with reintervention. Using a receiver operating characteristics curve, a predictive model for reintervention with all the above predictors yielded an area under the curve of 82%. All eight patients with both high MCM7 and high Ki-67 needed reintervention., Conclusion: This cohort study shows that expression of MCM7 is a predictor for clinically significant postoperative tumour progression. Together with age, Ki-67 and mitotic index, MCM7 might be of added value as a predictive marker when managing patients with NFPA after surgery.

In a seminal paper from 1990, Rosen and Bengtsson suggested that hypopituitary patients with a presumed growth hormone (GH) deficiency (GHD) have an excess mortality. Later studies have confirmed this finding but have also shown that the cause of the increased risk of death in these patients is multifactorial, including unreplaced GHD as well as non-physiological replacement therapy of other deficiencies, the etiology of hypopituitarism, and the side effects of tumor treatment. Only a few studies have investigated mortality in hypopituitary patients with GHD receiving GH replacement therapy (GHRT): these studies are retrospective observational studies with a wide range of underlying diseases but most of them show a mortality that is not different from the general population. Even though the research field of survival in GHD patients with and without GHRT is lacking prospective randomized trials, the evidence suggests that GHD in hypopituitary patients contributes to an excess mortality and modern replacement therapy including GHRT will result in a mortality that is approaching normal. Herein, we review the literature in the field of survival in GHD patients with and without GHRT. In addition, we outline the most important issues when evaluating studies in this area.

Background: The reported associations for several per- and polyfluoroalkyl substance (PFAS) with thyroid hormones are inconsistent in epidemiological studies. The purpose of the current study was to investigate the possible association of thyroid hormones in relation to serum levels of perfluorohexane sulfonate, perfluorooctane sulfonate and perfluorooctanoic acid, in a Swedish general population, highly exposed through contaminated drinking water, and if the associations with PFAS remained in a comparison to a reference group based only on residency in areas with contrasting PFAS levels., Method: 3297 participants from Ronneby, a municipality with drinking water highly contaminated by PFAS (exposed group), and a reference group (N = 226) from a nearby municipality with non-contaminated drinking water supply were included. Regression analysis was used to investigate the associations between PFAS exposure, assessed as exposure groups (Ronneby and reference groups) and measured serum PFAS levels, and thyroid hormone levels, with adjustments for age, sex and BMI., Result: No cross-sectional associations were found between PFAS and thyroid hormones in adults and seniors except for a positive association between PFAS and fT4 in males over 50. Higher thyroid hormone levels were found in the preteen children from Ronneby compared to the reference group. In contrast, within Ronneby, there was weak evidence of associations between increased PFAS levels and decreased fT3 in preteen boys, and decreased TSH in teenage males. No such pattern was found in preteen and teenage girls., Conclusion: The present study found no consistent evidence to support association of PFAS with thyroid hormones., (Copyright © 2020 Elsevier Inc.

Objectives  Despite the limited invasiveness of endoscopic transsphenoidal surgery (ETSS), some degree of nasal structure destruction is unavoidable. Our objective was to evaluate sinonasal morbidity and self-reported health before and 6 months after ETSS for pituitary tumors, and to identify possible predictive factors for deterioration in sinonasal health. Design  Prospective observational cohort study. Setting  University tertiary referral hospital. Participants  Totally 109 consecutive adult patients undergoing ETSS for pituitary tumors between 2015 and 2019. Main Outcome Measures  Sinonasal symptoms and self-reported health before and 6 months after ETSS, assessed by the Sinonasal Outcome Test (SNOT-22) and the EQ-5D questionnaire. Predictive factors for postoperative deterioration in sinonasal symptoms. Results  The overall SNOT-22 score did not change, but the score of the rhinologic domain of SNOT-22 worsened from 6.0 ± 5.9 before to 8.0 ± 7.4 6 months after surgery ( p  = 0.011). The EQ-5D visual analog scale improved from 64.0 ± 22.9 before to 71.1 ± 18.7 6 months after surgery ( p  = 0.00088). Univariate and multivariable regression analyses showed that prior sinonasal surgery was associated with a significant worsening in rhinologic symptoms 6 months after surgery ( p  = 0.046 and p  = 0.020, respectively). Conclusions  Although self-reported overall health improved, significant deterioration of rhinologic symptoms was seen 6 months after ETSS. This information is important for preoperative patient counselling. Further refinement of the surgical technique and follow-up strategies to reduce postoperative sinonasal morbidity could be of value, especially in patients who have undergone prior sinonasal surgery., Competing Interests: Conflict of interest D.S.O. has served as a consultant for Ipsen, Pfizer, Novo Nordisk, and Sandoz, and has received research grants from Sandoz.

Background: In December 2013, it was discovered that drinking water supplied to one third of the households in Ronneby, southern Sweden, was highly contaminated by PFAS (sum level >10,000 ng/L) originated from firefighting foams used at a nearby military airport., Objectives: To report serum PFAS levels of Ronneby residents participating in a biomonitoring program, and to describe the variation by age, sex and calendar period for residential exposure. In addition, a reference group living in a neighboring municipality without PFAS contaminated drinking water was examined., Methods: Blood samples and demographic data were collected for 3297 Ronneby residents and 226 individuals from the reference group. Yearly residence addresses were available for 3086 Ronneby residents from the national population registry. Serum concentrations of PFHxS, PFOS and PFOA were determined in all participants, with additional PFHpA, PFNA and PFDA in subsets of the participants., Results: The population geometric means for serum PFHxS, PFOS and PFOA were 114, 135 and 6.8 ng/mL for all Ronneby residents, i.e.135, 35 and 4.5 times higher than for the reference group. Ronneby residents who resided in the area with contaminated water supply during 2005-2013 showed much higher PFAS levels in 2014 than those exposed only before 2005. Ronneby residents who never resided in the area with contaminated water supply also had higher serum PFAS levels than the reference group. All three PFAS were highly correlated (r s  > 0.9 for each pair). Serum PFAS levels were lowest in teenage years and then increased with age. Adult females had lower PFAS levels on average than males under the age of 60 but higher above 60., Discussion: The results reveal high serum PFAS levels dominated by PFHxS and PFOS in the Ronneby residents highly exposed to PFAS originated from firefighting foams. The PFAS exposure in Ronneby permits studies of associations to a range of health parameters, as well as studies of the toxicokinetics of PFAS exposure., (Copyright © 2020 The Author(s).

Objective: Carpal tunnel syndrome (CTS) is common in patients with acromegaly, with a reported prevalence of 19-64%. We studied CTS in a large national cohort of patients with acromegaly and the temporal relationship between the two diagnoses., Design: Retrospective, nationwide, cohort study including patients diagnosed with acromegaly in Sweden, 2005-2017, identified in the Swedish Healthcare Registries., Methods: CTS (diagnosis and surgery in specialised healthcare) was analysed from 8.5 years before the diagnosis of acromegaly until death or end of the study. Standardised incidence ratios (SIRs) with 95% CIs were calculated for CTS with the Swedish population as reference., Results: The analysis included 556 patients with acromegaly (50% women) diagnosed at mean (s.d.) age 50.1 (15.0) years. During the study period, 48 patients were diagnosed with CTS and 41 patients underwent at least one CTS surgery. In the latter group, 35 (85%) were operated for CTS before the acromegaly diagnosis; mean interval (range) 2.2 (0.3-8.5) years and the SIR for having CTS surgery before the diagnosis of acromegaly was 6.6 (4.8-8.9). Women with acromegaly had a higher risk for CTS than men (hazard ratio: 2.5, 95% CI: 1.3-4.7)., Conclusions: Patients with acromegaly had a 6-fold higher incidence for CTS surgery before the diagnosis of acromegaly compared with the general population. The majority of patients with both diagnoses were diagnosed with CTS prior to acromegaly. Increased awareness of signs of acromegaly in patients with CTS might help to shorten the diagnostic delay in acromegaly, especially in women.

Context: Patients with craniopharyngioma suffer from obesity and impaired bone health. Little is known about longitudinal changes in body composition and bone mineral density (BMD)., Objective: To describe body composition and BMD (change)., Design: Retrospective longitudinal study., Setting: Two Dutch/Swedish referral centers., Patients: Patients with craniopharyngioma (n = 112) with a dual X-ray absorptiometry (DXA) scan available (2 DXA scans, n = 86; median Δtime 10.0 years; range 0.4-23.3) at age ≥ 18 years (58 [52%] male, 50 [45%] childhood onset)., Main Outcome Measures: Longitudinal changes of body composition and BMD, and associated factors of ΔZ-score (sex and age standardized)., Results: BMI (from 28.8 ± 4.9 to 31.2 ± 5.1 kg/m2, P < .001), fat mass index (FMI) (from 10.5 ± 3.6 to 11.9 ± 3.8 kg/m2, P = .001), and fat free mass index (FFMI) (from 18.3 ± 3.2 to 19.1 ± 3.2 kg/m2, P < .001) were high at baseline and increased. Fat percentage and Z-scores of body composition did not increase, except for FFMI Z-scores (from 0.26 ± 1.62 to 1.06 ± 2.22, P < .001). Z-scores of total body, L2-L4, femur neck increased (mean difference 0.61 ± 1.12, P < .001; 0.74 ± 1.73, P < .001; 0.51 ± 1.85, P = .02). Linear regression models for ΔZ-score were positively associated with growth hormone replacement therapy (GHRT) (femur neck: beta 1.45 [95% CI 0.51-2.39]); and negatively with radiotherapy (femur neck: beta -0.79 [-1.49 to -0.09]), glucocorticoid dose (total body: beta -0.06 [-0.09 to -0.02]), and medication to improve BMD (L2-L4: beta -1.06 [-1.84 to -0.28])., Conclusions: Z-scores of BMI, fat percentage, and FMI remained stable in patients with craniopharyngioma over time, while Z-scores of FFMI and BMD increased. Higher glucocorticoid dose and radiotherapy were associated with BMD loss and GHRT with increase., (© The Author(s) 2020. Published by Oxford University Press on behalf of the Endocrine Society.

Context: Whether multisystem morbidity in Cushing's disease (CD) remains elevated during long-term remission is still undetermined., Objective: To investigate comorbidities in patients with CD., Design, Setting, and Patients: A retrospective, nationwide study of patients with CD identified in the Swedish National Patient Register between 1987 and 2013. Individual medical records were reviewed to verify diagnosis and remission status., Main Outcomes: Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were calculated by using the Swedish general population as reference. Comorbidities were investigated during three different time periods: (i) during the 3 years before diagnosis, (ii) from diagnosis to 1 year after remission, and (iii) during long-term remission., Results: We included 502 patients with confirmed CD, of whom 419 were in remission for a median of 10 (interquartile range 4 to 21) years. SIRs (95% CI) for myocardial infarction (4.4; 1.2 to 11.4), fractures (4.9; 2.7 to 8.3), and deep vein thrombosis (13.8; 3.8 to 35.3) were increased during the 3-year period before diagnosis. From diagnosis until 1 year after remission, SIRs (95% CI were increased for thromboembolism (18.3; 7.9 to 36.0), stroke (4.9; 1.3 to 12.5), and sepsis (13.6; 3.7 to 34.8). SIRs for thromboembolism (4.9; 2.6 to 8.4), stroke (3.1; 1.8 to 4.9), and sepsis (6.0; 3.1 to 10.6) remained increased during long-term remission., Conclusion: Patients with CD have an increased incidence of stroke, thromboembolism, and sepsis even after remission, emphasizing the importance of early identification and management of risk factors for these comorbidities during long-term follow-up., (© Endocrine Society 2020.

Background: Patients with pituitary tumors often live with lifelong consequences of their disease. Treatment options include surgery, radiotherapy, and medical therapy. Symptoms associated with the tumor or its treatment affect several areas of life. Patients need to adhere to long-term contact with both specialist and general health care providers due to the disease, complex treatments, and associated morbidity. The first year after pituitary surgery constitutes an important time period, with medical evaluations after surgery and decisions on hormonal substitution. The development and evaluation of extended patient support during this time are limited., Objective: The aim of this study is to evaluate whether support within a person-centered care practice increases wellbeing for patients with pituitary tumors. Our main hypothesis is that the extended support will result in increased psychological wellbeing compared with the support given within standard of care. Secondary objectives are to evaluate whether the extended support, compared with standard care, will result in (1) better health status, (2) less fatigue, (3) higher satisfaction with care, (4) higher self-efficacy, (5) increased person-centered content in care documentation, and (6) sustained patient safety., Methods: Within a quasiexperimental design, patients diagnosed with a pituitary tumor planned for neurosurgery are consecutively included in a pretest-posttest study performed at a specialist endocrine clinic. The control group receives standard of care after surgery, and the interventional group receives structured patient support for 1 year after surgery based on person-centeredness covering self-management support, accessibility, and continuity. A total of 90 patients are targeted for each group., Results: Recruitment into the control group was performed between Q3 2015 and Q4 2017. Recruitment into the intervention group started in Q4 2017 and is ongoing until Q4 2020. The study is conducted according to the Declaration of Helsinki, and the protocol has received approval from a regional ethical review board., Conclusions: This study entails an extensive intervention constructed in collaboration between clinicians, patients, and researchers that acknowledges accessibility, continuity, and self-management support within person-centeredness. The study has the potential to compare standard care to person-centered practice adapted specifically for patients with pituitary tumors and evaluated with a combination of patient-reported outcomes and patient-reported experience measures. Following the results, the person-centered practice may also become a useful model to further develop and explore person-centered care for patients with other rare, lifelong conditions., Trial Registration: Researchweb.org. https://www.researchweb.org/is/sverige/project/161671., International Registered Report Identifier (irrid): DERR1-10.2196/17697., (©Sofie Jakobsson, Daniel S Olsson, Eva Andersson, Tobias Hallén, David Krabbe, Ann-Charlotte Olofsson, Oskar Ragnarsson, Thomas Skoglund, Gudmundur Johannsson, Eva Jakobsson Ung.

Context: Clinical features of acromegaly develop insidiously. Its diagnosis may therefore be delayed., Objective: Our aim was to study diagnostic delay and its impact on morbidity and mortality in a nationwide cohort of patients with acromegaly., Design: Adult patients diagnosed with acromegaly between 2001 and 2013 were identified in the Swedish National Patient Registry. Diagnostic codes for predefined comorbidities associated with acromegaly were recorded between 1987 and 2013. Diagnostic delay was calculated as the time between the first registered comorbidity and the diagnosis of acromegaly., Results: A total of 603 patients (280 men, 323 women) with acromegaly were included. Mean (s.d.) diagnostic delay was 5.5 (6.2) years (median (minimum, maximum) 3.3 (0.0-25.9)) Diagnostic delay was 1-<5 years in 23% patients; 5-<10 years in 17%; and ≥10 years in 24%. No delay was recorded in 36% of patients. Overall, mean (s.d.) number of comorbidities was 4.1 (2.5) and was higher in patients with longer diagnostic delay (P < 0.0001). Overall, observed number of deaths was 61 (expected 42.2), resulting in a standardized mortality ratio (SMR) of 1.45 (95% CI: 1.11-1.86). Increased mortality was only found in patients with the longest diagnostic delay (1.76, 95% CI: 1.12-2.65). In the other groups, no statistically significant increase in mortality was recorded, with the numerically lowest SMR observed in patients without diagnostic delay (1.18; 95% CI: 0.68-1.92)., Conclusions: The diagnosis of acromegaly is delayed in most patients. Prolonged diagnostic delay is associated with increased morbidity and mortality.

Context: Pituitary hormonal deficiencies in patients with craniopharyngioma may impair their bone health., Objective: To investigate bone health in patients with craniopharyngioma., Design: Retrospective cross-sectional study., Setting: Dutch and Swedish referral centers., Patients: Patients with craniopharyngioma (n = 177) with available data on bone health after a median follow-up of 16 years (range, 1-62) were included (106 [60%] Dutch, 93 [53%] male, 84 [48%] childhood-onset disease)., Main Outcome Measures: Fractures, dual X-ray absorptiometry-derived bone mineral density (BMD), and final height were evaluated. Low BMD was defined as T- or Z-score ≤-1 and very low BMD as ≤-2.5 or ≤-2.0, respectively., Results: Fractures occurred in 31 patients (18%) and were more frequent in men than in women (26% vs. 8%, P = .002). Mean BMD was normal (Z-score total body 0.1 [range, -4.1 to 3.5]) but T- or Z-score ≤-1 occurred in 47 (50%) patients and T-score ≤-2.5 or Z-score ≤-2.0 in 22 (24%) patients. Men received less often treatment for low BMD than women (7% vs. 18%, P = .02). Female sex (OR 0.3, P = .004) and surgery (odds ratio [OR], 0.2; P = .01) were both independent protective factors for fractures, whereas antiepileptic medication was a risk factor (OR, 3.6; P = .03), whereas T-score ≤-2.5 or Z-score ≤-2.0 was not (OR, 2.1; P = .21). Mean final height was normal and did not differ between men and women, or adulthood and childhood-onset patients., Conclusions: Men with craniopharyngioma are at higher risk than women for fractures. In patients with craniopharyngioma, a very low BMD (T-score ≤-2.5 or Z-score ≤-2.0) seems not to be a good predictor for fracture risk., (© Endocrine Society 2020.)

Objective: Excess of growth hormone (GH) and insulin-like growth factor 1 (IGF-1), as in acromegaly, is associated with increased risk of diabetes, but whether retinal vessels are altered is unknown. The aim of this study was to evaluate retinal vessel morphology in patients with acromegaly at diagnosis and after treatment and to describe the prevalence of diabetic retinopathy in patients with long-standing acromegaly and diabetes., Design: Two independent observational studies, one being prospective and the other retrospective and cross-sectional., Methods: Retinal vessel morphology of 26 patients with acromegaly was examined at diagnosis and 1 year after treatment and compared to 13 healthy controls. Cross-sectional evaluation of 39 patients with long-standing acromegaly and diabetes was performed. Fundus photographs were digitally analyzed for vessel morphology., Results: Patients with acromegaly had a median (interquartile range) of 34.3 (30.0-39.0) vessel branching points compared to 27.0 (24.0-29.0) for healthy controls (P < 0.001). Tortuosity of arterioles and venules remained unchanged. Vessel morphology did not change significantly after treatment. Patients with acromegaly and diabetes for a median of 14 years also had a high number of branching points (34.2 (32.5-35.6)), but the prevalence of diabetic retinopathy was not higher than expected in diabetic patients without acromegaly., Conclusions: Patients with acromegaly have an increased number of vascular branching points in the retina without an alteration of macroscopic vessel morphology. This is consistent with an angiogenic effect of GH/IGF-1 in humans. The prevalence of diabetic retinopathy was not increased in patients with acromegaly and diabetes.

Objective: Glucocorticoids (GCs) are a cornerstone in treating various common and uncommon diseases. The aim of this study was to estimate the prevalence of GC use in terms of doses associated with risk of tertiary adrenal insufficiency in adults and children, and treatment indications., Methods: This was a retrospective cohort study. Information on dispensed prescriptions was obtained from the Swedish Prescribed Drug Register. Patients with prescriptions of prednisolone (or equivalent dose of other GCs) ≥5 mg daily for ≥21 days between 2007 and 2014 were included. Information on concurrent diseases was obtained from the Swedish National Patient Register and the Västra Götaland Regional Healthcare Database., Results: Of 1 585 335 inhabitants in Västra Götaland County, 223 211 were included in the study (women 55.6%). Mean age was 48 ± 24 years. Period prevalence of oral GC use during the 8-year study period was 14.1%. The highest prevalence (27.4%) was in men aged 80-89 years and lowest (7.5%) in men 10-19 years of age. The period prevalence in children 0-9 years of age was 10.6%. COPD and asthma were the most common indications for treatment (17.2%) followed by allergy (12.5%) and malignant neoplasms (11.5%). Allergy was the most frequent indication (20.5%) in children and adolescents., Conclusion: Between 2007 and 2014, every seventh inhabitant in western Sweden received a GC prescription at doses associated with risk of developing tertiary adrenal insufficiency. These findings illustrate the importance of awareness of the potential development of tertiary adrenal insufficiency in both paediatric and adult patients., (© 2019 John Wiley & Sons Ltd.)

Growth hormone (GH) deficiency (GHD) in adults is well-characterized and includes abnormal body composition, reduced bone mass, an adverse cardiovascular risk profile, and impaired quality of life. In the early 1990s, it was also shown that patients with hypopituitarism without GH replacement therapy (GHRT) had excess mortality. Today, GHRT has been shown to decrease or reverse the negative effects of GHD. In addition, recent papers have shown that mortality and morbidity are approaching normal in hypopituitary patients with GHD who receive modern endocrine therapy including GHRT. Since the first dose-finding studies, it has been clear that efficacy and side effects differ substantially between patients. Many factors have been suggested as affecting responsiveness, such as sex, age, age at GHD onset, adherence, and GH receptor polymorphisms, with sex and sex steroid replacement having the greatest impact. Therefore, the individual tailoring of GH dose is of great importance to achieve sufficient efficacy without side effects. One group that stands out is women receiving oral estrogen replacement, who needs the highest dose. Serum insulin-like growth factor-1 (IGF-1) is still the most used biochemical biomarker for GH dose titration, although the best serum IGF-1 target is still debated. Patients with GHD due to acromegaly, Cushing's disease, or craniopharyngioma experience similar effects from GHRT as others. Arch Endocrinol Metab. 2019;63(6):592-600.

Per- and polyfluoroalkyl substances (PFAS) are extremely persistent manmade substances. Apart from exposure through food and indoor air and dust, humans can be exposed through drinking water if the surface or groundwater is contaminated. In 2013 very high levels of PFOS and PFHxS were found in the drinking water from one of the two waterworks supplying the municipality of Ronneby, Sweden. A cohort was formed, including all individuals who had lived at least one year in Ronneby during the period 1980-2013 (ñ63,000). Each year, addresses that got their drinking water from the contaminated water works were identified. Through the Swedish personal identity number, each individual was linked to registers providing diagnoses and prescriptions for hyper- and hypothyroidism. In total, 16,150 individuals had ever been exposed. The hazard ratios did not indicate any excess risk of hyperthyroidism among those with contaminated water. For hypothyroidism, the risk of being prescribed medication was significantly increased among women with exposure during the mid part of the study period (but not men). However, the association with period of exposure was non-monotonic, so the significance is considered to be a chance finding. Our research was limited by the relatively simple exposure assessment., (Copyright © 2019 The Authors. Published by Elsevier Inc. All rights reserved.)

Purpose: Non-functioning pituitary adenomas (NFPAs) are associated with impaired well-being, increased comorbidities, and reduced long-term survival. Data on optimal management of NFPAs around surgical treatment are scarce, and postoperative treatment and follow-up strategies have not been evaluated in prospective trials. Here, we review the preoperative, perioperative, and early postoperative management of patients with NFPAs., Methods: We searched Medline and the Cochrane Library for articles published in English with the following items "Pituitary neoplasms AND Surgery" and "Surgery AND Hypopituitarism". Studies containing detailed analyses of the management of NFPAs in adult patients, including pituitary surgery, endocrine care, imaging, ophthalmologic assessment and long-term outcome were reviewed., Results: Treatment options for NFPAs include active surveillance, surgical resection, and radiotherapy. Pituitary surgery is currently recommended as first-line treatment in patients with visual impairment due to adenomas compressing the optic nerves or chiasma. Radiotherapy is reserved for large tumor remnants or tumor recurrence following one or more surgical attempts. There is no consensus of optimal pre-, peri-, and postoperative management such as timing, frequency, and duration of endocrine, radiologic, and ophthalmologic assessments as well as management of smaller tumor remnants or tumor recurrence., Conclusions: In clinical practice, there is a great variation in the treatment and follow-up of patients with NFPAs. We have, based on available data, suggested an optimal management strategy for patients with NFPAs in relation to pituitary surgery. Prospective trials oriented at drawing up strategies for the management of NFPAs are needed.

Objective: To investigate the contemporary presentation of pituitary metastases., Patients: Thirty-eight patients diagnosed with pituitary metastases from 1996 to 2018 in Sweden., Methods: Pituitary metastases were confirmed by histopathology (n = 27) or considered highly likely according to radiological findings, including rapid tumor progression (n = 11). Medical records were reviewed and sellar images reexamined centrally., Results: Breast and lung cancers were the most common primary tumors, in 45% and 21% of patients, respectively. Sixty-seven percent of breast cancers overexpressed human epidermal growth factor receptor 2 (HER2); 53% of pituitary metastases from breast cancers appeared ≥10 years after diagnosis of the primary tumor. At presentation, 71% appeared to have ACTH deficiency, 65% had TSH deficiency, and 26% had diabetes insipidus. Fatigue, nausea/vomiting, loss of appetite, weight loss, myalgia, and/or arthralgia were reported in 47% of patients with morning cortisol <100 nmol/L vs 23% with cortisol ≥200 nmol/L. Sixteen patients had visual field defects, and eight had diplopia. Intrasellar and suprasellar tumor growth was the most frequent finding. Initially, a pituitary adenoma was considered the etiology in 18% of patients.Radiotherapy, pituitary surgery, and chemotherapy were used in 68%, 68%, and 11% of patients, respectively. One and 2 years after diagnosis of pituitary metastases, 50% and 26% of patients were alive., Conclusion: Pituitary metastases may be mistaken for pituitary adenomas and can appear late, especially in breast cancer. Breast cancers overexpressing HER2 seem prone to metastasize to the pituitary. Hypocortisolism may be misdiagnosed as cancer-related malaise. An increased awareness of pituitary metastases and undiagnosed pituitary failure can improve management in these patients., (Copyright © 2019 Endocrine Society.)

Objective: Craniopharyngioma patients often have poor metabolic profiles due to hypothalamic-pituitary damage. Previously, using BMI as obesity marker, the occurrence of the metabolic syndrome in these patients was estimated at 46%. Our aim was to determine if dual X-ray absorptiometry (DXA) scan in evaluation of obesity and metabolic syndrome would be superior., Design: Retrospective study of craniopharyngioma patients for whom DXA scan results were available., Methods: BMI, fat percentage and fat mass index were used to evaluate obesity and as components for obesity in metabolic syndrome., Results: Ninety-five craniopharyngioma patients were included (51% female, 49% childhood-onset disease). Metabolic syndrome occurred in 34-53 (45-51%) subjects (depending on the definition of obesity, although all definitions occurred in higher frequency than in the general population). Metabolic syndrome frequency was higher if obesity was defined by fat percentage (52 vs 42%) or fat mass index (51 vs 43%) compared to BMI. Misclassification appeared in 9% (fat percentage vs BMI) and 7% (fat mass index vs BMI) for metabolic syndrome and 29 and 13% for obesity itself, respectively. For metabolic syndrome, almost perfect agreement was found for BMI compared with fat percentage or fat mass index. For obesity, agreement was fair to moderate (BMI vs fat percentage)., Conclusion: Using BMI to evaluate obesity underestimates the true prevalence of metabolic syndrome in patients with craniopharyngioma. Furthermore, fat percentage contributes to a better evaluation of obesity than BMI. The contribution of DXA scan might be limited for identification of the metabolic syndrome.

Objective: Experiences and need of support during surgery and start of replacement therapy in patients with pituitary tumours are highly unknown. This study aimed at exploring patient experiences during pre- and postoperative care and recovery after pituitary surgery in patients with a pituitary tumour., Methods: Within a qualitative study design, 16 consecutive patients who underwent surgery for pituitary tumours were repeatedly interviewed. In total, 42 interviews were performed before and after surgery. Analysis was performed using qualitative interpretation., Results: Suffering a pituitary tumour was overwhelming for many patients and struggling with existential issues was common. Patients expressed loneliness and vulnerability before and after surgery. How professionals handled information in connection with diagnosis greatly affected the patients. Other patients with the same diagnosis were experienced as the greatest support. Normalisation of bodily symptoms and relationships with others were reported during postoperative recovery. However, a fear that the tumour would return was present., Conclusions: Patients with pituitary tumours need structured support, including peer support, which acknowledges physical, cognitive as well as emotional and existential concerns. Information related to diagnosis and surgery should be adapted in relation to the loneliness and the existential seriousness of the situation. Care and support for patients with pituitary tumours should preferably be organised based on continuity and an unbroken care pathway from the first pre-operative evaluation through to postoperative care and the start of a life-long endocrine treatment and tumour surveillance.

Context: Whether patients with Cushing disease (CD) in remission have increased mortality is still debatable., Objective: To study overall and disease-specific mortality and predictive factors in an unselected nationwide cohort of patients with CD., Design, Patients, and Methods: A retrospective study of patients diagnosed with CD, identified in the Swedish National Patient Registry between 1987 and 2013. Medical records were systematically reviewed to verify the diagnosis. Standardized mortality ratios (SMRs) with 95% CIs were calculated and Cox regression models were used to identify predictors of mortality., Results: Of 502 identified patients with CD (n = 387 women; 77%), 419 (83%) were confirmed to be in remission. Mean age at diagnosis was 43 (SD, 16) years and median follow-up was 13 (interquartile range, 6 to 23) years. The observed number of deaths was 133 vs 54 expected, resulting in an overall SMR of 2.5 (95% CI, 2.1 to 2.9). The commonest cause of death was cardiovascular diseases (SMR, 3.3; 95% CI, 2.6 to 4.3). Excess mortality was also found associated with infections and suicide. For patients in remission, the SMR was 1.9 (95% CI, 1.5 to 2.3); bilateral adrenalectomy and glucocorticoid replacement therapy were independently associated with increased mortality, whereas GH replacement was associated with improved outcome., Conclusion: Findings from this large nationwide study indicate that patients with CD have excess mortality. The findings illustrate the importance of achieving remission and continued active surveillance, along with adequate hormone replacement and evaluation of cardiovascular risk and mental health., (Copyright © 2019 Endocrine Society.)
