RESUMO
INTRODUCTION: To assess outcome of a one-time human papillomavirus (HPV)-screening in 2017 of Danish women aged 70+. MATERIAL AND METHODS: Women born 1947 or before were personally invited to have a cell-sample collected by their general practitioner. Screening- and follow-up samples were analyzed in hospital laboratories in the five Danish regions and registered centrally. Follow-up procedures varied slightly across regions. Cervical intraepithelial neoplasia 2 (CIN2) was recommended treatment threshold. Data were retrieved from the Danish Quality Database for Cervical Cancer Screening. We calculated CIN2+ and CIN3+ detection rates per 1000 screened women, and number of biopsies and conizations per detected CIN2+ case. We tabulated annual number of incident cervical cancer cases in Denmark for the years 2009-2020. RESULTS: In total, 359 763 women were invited of whom 108 585 (30% of invited) were screened; 4479 (4.1% of screened, and 4.3% of screened 70-74 years) tested HPV-positive; of whom 2419 (54% of HPV-positive) were recommended follow-up with colposcopy, biopsy and cervical sampling, and 2060 with cell-sample follow-up. In total, 2888 women had histology; of whom 1237 cone specimen and 1651 biopsy only. Out of 1000 screened women 11 (95% confidence interval [CI]: 11-12) had conization. In total, 579 women had CIN2+; 209 CIN2, 314 CIN3, and 56 cancer. Out of 1000 screened women five (95% CI: 5-6) had CIN2+. Detection rate of CIN2+ was highest in regions where conization was used as part of first-line follow-up. In 2009-2016, number of incident cervical cancers in women aged 70+ in Denmark fluctuated around 64; in 2017 it reached 83 cases; and by 2021 the number had decreased to 50. CONCLUSIONS: The prevalence of high-risk HPV of 4.3% in women aged 70-74 is in agreement with data from Australia, and the detection of five CIN+2 cases per 1000 screened women is in agreement with data for 65-69 year old women in Norway. Data are thus starting to accumulate on primary HPV-screening of elderly women. The screening resulted in a prevalence peak in incident cervical cancers, and it will therefore take some years before the cancer preventive effect of the screening can be evaluated.

STUDY QUESTION: Is the risk of high-grade precancerous cervical lesions and/or is the risk of lesion progression increased in users of a hormone-containing intrauterine device (HIUD) compared with users of other contraceptive methods. SUMMARY ANSWER: Women starting use of HIUD had the same subsequent risk of cervical intraepithelial neoplasia 3+ (CIN3+) as copper IUD (CIUD) users, and both groups tended to have lower risks than oral contraceptives (OC) users. WHAT IS KNOWN ALREADY: HIUDs may cause inflammatory and immunosuppressive changes that may potentially affect the risk of persistent human papillomavirus infection and precancerous cervical lesions. STUDY DESIGN, SIZE, DURATION: A Danish population-based cohort study was conducted using register data from 2008 to 2011 on 26-50-year-old users of HIUD (n = 60 551), CIUD (n = 30 303), or OC (n = 165 627). PARTICIPANTS/MATERIALS, SETTING, METHODS: Within each user group, women were divided into two groups; normal cytology or abnormal diagnosis before start of contraceptive use (baseline). Follow-up histology and cytology diagnoses were registered during the 5 years after baseline. Adjusted relative risks (aRR) and 95% CI were calculated for precancerous cervical lesions in HIUD users compared with CIUD and OC users. MAIN RESULTS AND THE ROLE OF CHANCE: Women with normal cytology at baseline: at follow-up HIUD users had the same risk of CIN3 or higher (3+) as CIUD users; aRR 1.08 (95% CI 0.94-1.22). For the HIUD and CIUD groups compared with OCs, the risks of CIN3+ were lower: aRR 0.63 (95% CI 0.57-0.69) and aRR 0.58 (95% CI 0.52-0.65), respectively. The same was observed for CIN2 risks: aRR 0.86 (95% CI 0.76-0.96) and aRR 0.68 (95% CI 0.58-0.79) for HIUD and CIUD groups, respectively. Women with abnormal diagnosis at baseline: a lower progression risk, except for CIN2+ at baseline, was observed in HIUD users compared with OC users. Similar progression risks were found in HIUD and CIUD users. There were no differences between the three contraceptive groups in persistence or regression of present lesions. LIMITATIONS, REASONS FOR CAUTION: We adjusted for age, education, and region of residence as a proxy for socio-economic factors. Data on smoking and sexual behavior were not available thus we cannot exclude some differences between the three user groups. WIDER IMPLICATIONS OF THE FINDINGS: These findings suggest that women may safely use HIUDs. STUDY FUNDING/COMPETING INTEREST(S): A.P.

OBJECTIVE: To evaluate the impact of a cervical cancer (CC) diagnosis on use of health care and prescription drugs. METHODS: This population-based register-study included Danish women aged 23-59 years and diagnosed with CC in 2001-2005. Women with a cervical screening outcome were used as comparison group. We obtained number of contacts to general practitioners (GPs), hospitals, psychologists/psychiatrists and defined daily doses (DDD) of analgesic/psychotropic prescription drugs. A difference-in-differences-design was used to estimate effect of a CC diagnosis on health-care use from five-year periods before and after the diagnosis/screening outcome. RESULTS: In total, 926 women with CC and 1,004,759 women without cancer were included. In five years following the date of CC diagnosis, CC patients had increased their use of GPs with 8.6 (95% CI 4.8-12.4) contacts more than women in the comparison group, and with 4.12 (95% CI 3.99-4.25) more hospital contacts. In contrast, use of psychologists/psychiatrists was low and largely unaffected by the CC diagnosis. For use of prescription drugs, analgesics increased with 80 (95% CI 60-100) DDD more in CC patients than in comparison women, and for psychotropics with 304 (95% CI 261-347) DDD more. CONCLUSIONS: A CC diagnosis was followed by an increase in use of GPs, hospitals, and analgesic/psychotropic prescription drugs, while use of psychologist/psychiatrist was largely unaffected. This pattern may indicate that pain/mental health concerns after CC either persisted or were alleviated by other means only.

BACKGROUND: Condom use can reduce the risk of infection by human papillomavirus (HPV). Furthermore, it has been suggested that condom use can increase the regression rate of cervical lesions. In Denmark, women with cervical intraepithelial neoplasia grade 2 (CIN2) and a future wish to conceive are not treated immediately but are followed up by a gynecologist about 6 months later. The aim of this project was to determine if advising women to have their male partners to use a condom during sexual intercourse in the follow-up period can increase the regression rate of CIN2. METHODS/DESIGN: This is a randomized clinical trial of women with CIN2. The intervention group was advised to use condoms between the date of diagnosis and the date of their follow-up visit. The control group received standard care. Cervical samples were tested for HPV. The primary endpoint will be the intention-to-treat analysis with the relative rate of CIN2 regression between the intervention group and the control group. Regression is defined as Assuntos

RESUMO
Iron deficiency and iron deficiency anaemia are frequent complications to pregnancy and especially iron deficiency is underdiagnosed because of scarce symptoms. Due to the increased need for iron and the variation in iron storage in healthy pregnant women, iron supplementation should be individualised based on the level of haemoglobin and ferritin. First choice of treatment is oral iron supplementation, unless there is a failure of treatment, a known condition with malabsorption, or severe iron deficiency anaemia very close to due date. In these cases, intravenous iron may be considered.

BACKGROUND: Denmark is one of the countries where Human papillomavirus (HPV)-vaccination at present includes only girls. However, the burden of HPV-related cancer in men is increasing, which would argue for gender-neutral vaccination. The aim of this study was to examine the burden of HPV-caused cancers in women and men, and to evaluate the potential of HPV-vaccination in cancer control. METHODS: Data were retrieved from the literature on population prevalence of high risk (HR) HPV, on HR HPV-prevalence and genotypes in HPV-related cancers, and on number of cytology samples in cervical screening. Data on annual biopsies and conisations were retrieved from the Danish National Health Service Register and the Danish National Patient Register. Incidences of HPV-related cancers in Denmark were extracted from NORDCAN. Number of HPV-caused cancers was calculated from number of HPV-related cancers and the proportion known to be caused by high-risk (HR) HPV. RESULTS: In cross-sectional surveys in Denmark, one fifth of women and almost one third of men were found to be positive for HR HPV. Per year, 548 HPV-caused cancer cases were diagnosed in women and 234 in men, and twice as many cancers in women as in men were preventable with HPV vaccination. However, including screening prevented cervical cancers, the burden of cancers caused by HPV-infection would be 1300-2000 in women as compared to 234 in men. CONCLUSION: Taking screening prevented cervical cancers into account, the cancer control potential of HPV-vaccination is considerably higher in women than in men. HPV-vaccination could reduce the burden of screening on women and on health care resources.
