Prediagnostic use of menopausal hormone therapy and long-term survival of localized epithelial ovarian cancer: The Extreme study.

Use of menopausal hormone therapy (MHT) prior to an epithelial ovarian cancer (EOC) diagnosis has been suggested to be associated with improved survival. In a recent nationwide cohort study, we found that prediagnostic long-term MHT use, especially estrogen therapy (ET), was associated with improved long-term survival in women with nonlocalized EOC. Our aim was to investigate the influence of prediagnostic MHT use on long-term survival among women with localized EOC in the same nationwide study. Our study cohort comprised all women aged 50 years or older with an EOC diagnosis in Denmark 2000-2014 (n = 2097) identified from the Extreme study. We collected information on usage of systemic ET and estrogen plus progestin therapy (EPT) from the Danish National Prescription Registry. By using pseudo-values, 5- and 10-year absolute and relative survival probabilities were estimated with 95% confidence intervals (CIs) while adjusting for histology, comorbidity, and income. Relative survival probabilities >1 indicate better survival. The 5-year absolute survival probabilities were 61% and 56%, respectively, among women who were nonusers and users of prediagnostic MHT, whereas these numbers were 46% and 41%, respectively, regarding 10-year survival. Use of MHT was not significantly associated with an improved 5- or 10-year survival in women with localized EOC (5-year relative survival probability = 0.95, 95% CI: 0.89-1.02; 10-year relative survival probability = 0.92, 95% CI: 0.84-1.02). Similar findings were seen for systemic ET or EPT use. Our findings do not suggest a positive benefit from prediagnostic MHT use on long-term survival of localized EOC.

History of autoimmune disease and long-term survival of epithelial ovarian cancer: The extreme study.

OBJECTIVE: Patients with autoimmune disease may have impaired cancer survival. The aim was to investigate the association between autoimmune disease and ovarian cancer survival. METHODS: From the Extreme study, we included women diagnosed with epithelial ovarian cancer (EOC) in Denmark during 1990-2014 (n = 11,870). Information on exposure and covariates was retrieved from nationwide registries. Using pseudo-values, we estimated absolute and relative 5- and 10-year survival probabilities with 95% confidence intervals (CIs) for autoimmune diseases combined and for the four most common individual disorders in our study population, namely type 1 diabetes, rheumatoid arthritis, Graves' disease, and inflammatory bowel disease. RESULTS: The overall 5- and 10-year absolute survival probabilities were 35% and 24%, respectively, in women with EOC without autoimmune disease. Autoimmune diseases combined was not significantly associated with survival among women with EOC (5-year adjusted relative survival probability = 1.01, 95% CI: 0.94-1.09; 10-year adjusted relative survival probability = 0.90, 95% CI: 0.81-1.00). However, stratification by disease stage showed an impaired 10-year survival in women with autoimmune disease and a localized EOC (relative survival probability = 0.86, 95% CI: 0.76-0.97). None of the individual autoimmune diseases were statistically significantly associated with EOC survival. CONCLUSIONS: Only among women with localized EOC, there seemed to be a long-term survival loss associated with a history of autoimmune disease. In contrast, no significant association between a history of autoimmune disease and survival was observed in women with nonlocalized EOC where the survival is already low.

Employment, occupation, and income in adults with neurofibromatosis 1 in Denmark: a population- and register-based cohort study.

BACKGROUND: Little is known about employment status, occupation, and disposable income in adults with NF1. METHODS: From the Danish National Patient Registry and database of two national Centers for Rare Diseases, we identified 1469 adults with NF1, who were matched to 11,991 randomly selected population comparisons on sex and birth year and month. Annual information on employment, occupation and disposable income was ascertained from national registries in 1980-2019. RESULTS: Adults with NF1 had a lower odds ratio (OR) for employment [OR 0.71, 95% confidence interval (CI) 0.61-0.83] and higher OR for health-related unemployment (OR 2.94, 95% CI 2.16-3.96) at age 30 years than population comparisons, which persisted at age 40 and 50 years. Somatic diagnoses were associated with a higher OR for health-related unemployment in adults with NF1 than in the population comparisons. Adults with NF1 had a slightly lower disposable income, with a 14% (0.82-0.89) reduction observed among the youngest birth cohort. Furthermore, adults with NF1 were less likely to be in a high skilled occupation at ages 30, 40 and 50 years. CONCLUSION: Adults with NF1 have a lower employment rate, which was mainly due to health-related reasons and a slightly lower disposable income than adults without NF1. Thus, anticipation guidance for employment should be part of the management of NF1 families.

Physical and psychological symptom burden in patients and caregivers during follow-up care after curative surgery for cancers in the pancreas, bile ducts or duodenum.

BACKGROUND: The primary aim was to assess Health Related Quality of Life (HRQoL), anxiety and depression in patients and caregivers during follow-up care after curative treatment for cancer in the pancreas, duodenum, or bile ducts. The secondary aim was to assess dyadic coping and the burden of being a caregiver. MATERIALS AND METHODS: In this prospective observational cohort study, we included patients and caregivers at first follow-up visit to conduct the following: Demographic characteristics, The European Organization for Research and Treatment of Cancer Quality of Life, the pancreas and bile duct module, EQ5D 3L, GAD-7 and PHQ-9 at baseline, and at six and nine-months follow-up visit. Demographic characteristics, Dyadic Coping Inventory and Zarit Caregiver Burden Questionnaire were conducted at baseline and at nine-months of follow-up visit. RESULTS: The response rate was 42% with 104 of the 248 invited patients completing the questionnaires at baseline: 78 (75% of 104) after six and 69 (66% of 104) after nine months. The median (Q25,75) time for inclusion was 33.6 (13.4, 38) and 29.1 (18.3, 36) weeks after surgery for patients with pancreatic or duodenal cancer, and bile duct cancer, respectively. The response rate of caregivers was 88% with 75 of 85 completing the questionnaires. Fifty percent of patients with pancreatic or duodenal cancer had diarrhea at baseline. After six and nine months, this increased to 75%. Fatigue was the most prominent symptom in patients with bile duct cancer after nine months with 25% of patients scoring this as a clinical symptom. CONCLUSIONS: The study highlights the need to systematically screen physical and psychological symptoms in patients and caregivers during follow-up care after treatment for cancer in the pancreas, duodenum and bile ducts. Symptom management during follow-up care should be prioritized by clinicians.

Incidence of cervical precancerous lesions and cervical cancer in Denmark from 2000 to 2019: Population impact of multi-cohort vaccination against human papillomavirus infection.

In Denmark, vaccination against human papillomavirus (HPV) has been implemented in the children's vaccination program (January 2009) and in multiple catch-up cohorts (October 2008 in girls 13-15 years and in August 2012 in women up to 27 years). In the present study we estimate incidence of cervical intraepithelial neoplasia grade 3 (CIN3), adenocarcinoma in situ (AIS), squamous cell carcinoma (SCC) and adenocarcinoma (AC) during 2000-2019. All cases of CIN3 and AIS were identified from the nationwide Pathology Data Bank, while SCC and AC were identified from the Danish Cancer Registry. We calculated age-standardized incidence rates and estimated annual percentage change (EAPC) with corresponding 95% confidence interval (CI) for the periods before vaccination implementation (2000-2005), early after implementation of childhood HPV vaccination and the first catch-up vaccination program (2006-2012), and after implementation of the second catch-up program (2013-2019). For CIN3 and AIS, age-specific incidence rates and EAPCs were calculated. An increasing age-standardized incidence was observed before introduction of HPV vaccination (2000-2005) for CIN3 [EAPCCIN3 : 3.0 (95% CI 1.7 to 4.3)] and AIS [EAPCAIS : 3.5 (95% CI 0.7 to 6.4)]. In the most recent period (2013-2019), following implementation of the second catch-up program, a decrease was observed for both CIN3 [EAPCCIN3 : -6.5 (95% CI -8.3 to -4.8)], AIS [EAPCAIS : -8.7 (95% CI -12.3 to -5.1)] and for SCC [EAPCSCC : -3.9 (95% CI -7.5 to -0.2)]. In this study we document a decrease in the incidence of CIN3, AIS and SCC in the period after implementation of multi-cohort HPV vaccination in Denmark.

Positive psychology in the working environment. Job demands-resources theory, work engagement and burnout: A systematic literature review.

The purpose of the present systematic review is to examine the Job Demands-Resources (JD-R) model in order to pinpoint how applicable and relevant is the present theoretical framework in the 21st Century workplace environment. Initially, there will be an examination of the key concepts of the theory, followed by a brief investigation of the empirical validity and importance of the theory in the workplace environment. Then, there will be an empirical investigation of various studies of both cross-sectional and longitudinal nature in the form of a methodology, offering substantial empirical evidence that attests to the validity and effectiveness of the JD-R model in predicting work engagement and burnout-two independent and contrasting states of employee wellbeing, covering the entire spectrum from employee wellness to employee ill-health. We hope this review contributes to the advancement of the JD-R model, aiding researchers and practitioners to obtain a better understanding of the current state of the JD-R model, whilst also offering avenues for future development of the theory, ultimately resulting in a better prediction of employee wellbeing.

Long-term survival of nonlocalized epithelial ovarian cancer among women using menopausal hormone therapy prior to diagnosis: The extreme study.

Prediagnostic use of menopausal hormone therapy (MHT) has been suggested to be associated with improved survival of epithelial ovarian cancer (EOC). We investigated the potential long-term survival benefit of prediagnostic MHT use in women ≥50 years with nonlocalized EOC using the Extreme study including all women in Denmark registered with nonlocalized EOC during 2000 to 2014 (N = 3776). We obtained individual-level information on prediagnostic use of systemic estrogen therapy (ET) and estrogen plus progestin therapy (EPT) from the National Prescription Registry and estimated absolute and relative 5- and 10-year survival probabilities with 95% confidence intervals (CIs) using pseudo-values, taking into account histology, comorbidity, income and residual disease. Among women not having used prediagnostic MHT, 5- and 10-year absolute survival probabilities were 19% and 11%, respectively. Compared to MHT nonusers, prediagnostic systemic ET use for 3 to 4 years and ≥ 5 years was associated with 1.43 (95% CI: 1.01-2.02) and 1.22 (95% CI: 0.96-1.55) times higher 5-year survival probabilities, respectively. Ten-year survival probabilities were also increased but not statistically significantly. Among prediagnostic EPT users, increased 5-year (1.14, 95% CI: 0.85-1.53) and 10-year (1.38, 95% CI: 0.91-2.08) survival probabilities were observed after use for 3 to 4 years compared to MHT nonuse, whereas EPT use for ≥5 years was not associated with long-term survival of nonlocalized EOC. Our findings may suggest a better long-term survival of nonlocalized EOC in women having used long-term prediagnostic ET. However, the statistical precision of our results did not allow firm conclusions and more studies are needed.

Validation of the Patient Empowerment Strategies Questionnaire (PES-Q) in Greek adult patients with chronic insomnia: a pilot study on basic psychometric values.

AIM: The objectives of this study were to validate the Patient Empowerment Strategies Questionnaire (PES-Q) in a Greek sample and to study its psychometric properties in a sample of patients diagnosed with chronic insomnia. BACKGROUND: This is a validation of the PES-Q in Attikon General Hospital, School of Medicine, National and Kapodistrian University of Athens. The questionnaire was administered to 93 subjects aged between 18 and 85 years (mean age ± SD: 54.7 ± 15.2, 28% males). METHODS: The criterion validity of the questionnaire was tested with the use of four specific criteria: the Athens Insomnia Scale, the Pittsburg questionnaire (Pittsburg Sleep Quality Index), the Depression, Anxiety and Stress Scale, and the Self-Esteem Scale. FINDINGS: According to factor analysis results, the structure of the original scale was confirmed by the presence of one main factor in the Greek sample, explaining 40.1% of the variance of PES-Q queries. The questionnaire showed satisfactory reliability (Cronbach's α = 0.887). The results of the current study suggest that the PES-Q may be used as an accurate psychometric instrument for the purposes of chronic insomnia. Future research should examine the psychometric qualities of the PES-Q Greek version in a larger sample.

Retinal hemangioblastoma: prevalence, incidence and frequency of underlying von Hippel-Lindau disease.

BACKGROUND AND AIMS: We aimed to determine the frequency of von Hippel-Lindau disease (vHL) as the underlying cause of retinal hemangioblastoma and to estimate retinal hemangioblastoma incidence and prevalence in a national cohort study. METHODS: Through the national patient register and vHL research database, we identified 81 patients diagnosed with a retinal hemangioblastoma in Denmark between 1977 and 2014. Consent was obtained for 54 living and 10 deceased patients with retinal hemangioblastoma. For each participant, we collected medical records and family information. Almost all (63 of 64) participants were or had previously been tested for mutations in the VHL gene. RESULTS: Overall, 84% of the participants (54 of the 64) had vHL. Compared with the non-vHL patients, the vHL patients had their first retinal hemangioblastoma at a younger age (22.5 vs 40 years), and were more likely to have an asymptomatic first hemangioblastoma (80% vs 20%). Overall, 76% (41 of 54) of the vHL patients had a family history of vHL, while none of the patients without vHL did. Despite the rarity of the disease, on average more than eight new tumours are diagnosed each year due to multiple tumour development in vHL patients. The estimated prevalence of patients with retinal hemangioblastoma was up to 1 in 73 080 individuals. CONCLUSION: In the first national study in which almost all participants were genetically tested, vHL was the underlying cause of retinal hemangioblastoma in 84% of cases; more often than previously reported. We recommend that genetic and clinical vHL screening should be performed in all patients with retinal hemangioblastoma.

von Hippel-Lindau development in children and adolescents.

The autosomal dominant von Hippel-Lindau disease (vHL) is associated with a lifelong risk of tumor development, especially retinal and CNS hemangioblastomas, pheochromocytoma, and renal cell carcinoma. Knowledge of paediatric vHL development is limited, and current surveillance guidelines are based on expert opinions. We aimed to describe the course of vHL development in children and adolescents, focusing on age at first manifestation, manifestation frequencies, and types. The prevalence of vHL diagnosis as well as manifestations in childhood were evaluated based on 99 patients, who had started surveillance before 18 years: 37 Danish patients from the national vHL research database and 62 international patients reported in 15 articles. Overall, 70% (69 of 99) developed manifestations before 18 years (median age at first manifestation: 12 years (range: 6-17 years)). Thirty per cent (30 of 99) had developed more than one manifestation type; the most frequent were retinal (34%) and CNS (30%) hemangioblastomas. Among the 37 Danish patients, 85% (97 of 116) of their tumors were asymptomatic. Vision outcome is significantly improved in hemangioblastomas that are treated while still asymptomatic. We agree with current guidelines that retinal surveillance be performed from birth. The patients had their first CNS hemangioblastomas at the median ages of 13-14 years (range: 6-17 years). Further, 11% (4 of 37) of the Danish patients had CNS surgery in their teenage years. Although the cohort is too small to make definite conclusions about specific initiation ages, regular CNS surveillance from vHL patients' teenage years seems clinically relevant.

Prevalence, birth incidence, and penetrance of von Hippel-Lindau disease (vHL) in Denmark.

Von Hippel-Lindau disease (vHL) is a rare hereditary tumour predisposition with multiorgan involvement that is not always easily recognized. The disease is reported to be almost fully penetrant at age 60 years. Previous estimates of vHL prevalence and incidence are all regional and vary widely. Most are >20 years old and prone to selection bias because of inclusion of only clinically affected vHL patients who were diagnosed before genetic testing was available. In an unselected cohort of all known Danish carriers of a disease-causing VHL variant, we assessed vHL penetrance on a national basis. We further used national health registers to identify individuals who fulfilled the clinical diagnostic vHL criteria based on their registered diagnostic codes, but had not been diagnosed with vHL. We also assessed the medical histories of first-degree relatives to identify familial cases. This study gives the first national estimates of vHL prevalence (1 in 46 900 individuals) and birth incidence (1 in 27 300 live births). vHL has been underdiagnosed in Denmark, and as many as 25% of the overall vHL cohort (diagnosed+undiagnosed patients) have a missed diagnosis in spite of fulfilling the international diagnostic criteria. We found an overall penetrance of 87% at age 60 years. When considering only vHL patients who have not attended surveillance, 20% will still be asymptomatic at age 60 years. This should be considered in the context of genetic counselling, especially when assessing the risk of vHL in asymptomatic adult first-degree relatives who are often not genetically tested.
