Abstract
BACKGROUND In Denmark, a girls-only human papillomavirus (HPV) vaccination program was initiated in 2008-2009. The study aim was to assess the HPV prevalence and type distribution in younger men prior to HPV vaccination in men. METHODS The study population was younger men who attended information days regarding military service. At random days (2019-2020), 280 men were included. We collected questionnaire data regarding risk factors for HPV infection and a penile swab for HPV testing. We compared results in this study with those from a previous study of young men (2006-2007). RESULTS The majority of participants (94%) were 18-20 years old. The median number of lifetime sexual partners was 4. Altogether, 130 men (46.4%) were HPV positive. No infections with HPV types 6, 11, 16, 18, 31, and 45 were detected. The most frequent type was HPV-51 (detected in 11.1%). Comparison showed that the odds of high-risk HPV type infection were higher in 2019-2020 (prevalence odds ratio [POR], 1.7 [95% confidence interval {CI}, 1.1-2.7]) compared with 2006-2007. In contrast, the odds were lower (POR, 0.3 [95% CI, .1-.6]) for HPV types targeted by the 9-valent HPV vaccine. CONCLUSIONS The multicohort girls-only vaccination program has to a large degree protected young men against the HPV types included in the licensed vaccines. This does not speak against gender-neutral vaccination as the HPV prevalence is still high, although consisting largely of less carcinogenic HPV types.

Abstract
AIMS To estimate the incidence rates of genital warts (GWs) in women and men with type 1 diabetes compared to persons without diabetes. METHODS In this nationwide registry-based cohort study, we included the entire population aged 15 to 49 years living in Denmark between 1996 and 2016. From national registries, we retrieved individual level information on diabetes status, diagnoses and treatment of GWs, and potential confounding variables. We used Poisson regression to model sex- and age-specific incidence rates of GWs in persons with type 1 diabetes and persons without diabetes. Based on the models, we computed sex-specific incidence rate ratios (IRRs) of GWs in persons with type 1 diabetes compared to persons without diabetes, overall and according to age. RESULTS The analysis included 3,514,824 persons without type 2 diabetes and no GW diagnoses before baseline. The incidence rate of GWs in persons with type 1 diabetes was higher than in those without diabetes, both among women (IRR = 1.59; 95% CI, 1.42-1.78) and men (IRR = 1.36; 95% CI, 1.25-1.48). The pattern of increased incidence rates of GWs in persons with type 1 diabetes was seen at all ages. CONCLUSIONS Persons with type 1 diabetes have higher incidence rates of GWs than persons without diabetes. This supports the importance of HPV vaccination of young girls and boys with type 1 diabetes.

Abstract
BACKGROUND Diabetes may increase risk of human papillomavirus (HPV)-related precancer and cancer. We estimated incidence of penile and anal high-grade intraepithelial neoplasia (hgPeIN, hgAIN) and squamous cell carcinoma (SCC) in men with diabetes compared with the entire Danish male population without diabetes. METHODS In this registry-based cohort study, we included all men born 1916-2001 and residing in Denmark (n = 2,528,756). From nationwide registries, we retrieved individual-level information on diabetes, educational level, and diagnoses of hgPeIN, hgAIN, penile SCC, and anal SCC. We used Poisson regression models to estimate incidence of hgPeIN, hgAIN, penile SCC, and anal SCC as a function of diabetes status, attained age, calendar period, and education. We estimated incidence rate ratios (IRRs) of each outcome in men with diabetes compared with nondiabetic men, both for diabetes overall and separately for type 1 (T1D) and type 2 diabetes (T2D). RESULTS Men with diabetes had increased incidence rate of penile SCC compared with nondiabetic men (IRR = 1.5, 95% CI = 1.2, 1.9). We saw similar trends for anal SCC, hgPeIN, and hgAIN. The combined incidence rate of penile and anal SCC was increased in men with T2D (IRR = 1.5, 95% CI = 1.3, 1.8), but not with T1D (IRR = 0.53, 95% CI = 0.20, 1.4) compared with men without diabetes. CONCLUSION The incidence of penile and anal high-grade intraepithelial neoplasia and SCC in men with diabetes was increased compared with men without diabetes. For penile and anal SCCs, this was primarily due to an increased risk in men with T2D.

Abstract
In this register-based cohort study, we estimated the incidence of human papillomavirus (HPV)-related anogenital precancer and cancer in women with diabetes compared with women without diabetes. We followed all women living in Denmark born 1916 to 2001 (n = 2 508 321) for individual-level information on diabetes (Type 1 or 2 [T1D or T2D]), diagnoses of cervical, vaginal, vulvar and anal intraepithelial neoplasia Grade 2 or 3 (IN2/3) and cancer and other covariates from nationwide registries. We used Poisson regression to model the incidence rates of anogenital IN2/3 and cancer as a function of diabetes status, age, HPV vaccination, education, calendar year, and cervical cancer screening status. Incidence rate ratios (IRRs) were estimated for diabetes overall, and separately for T1D and T2D, compared with women without diabetes. Women with diabetes had higher rates of vulvar IN2/3 (IRR = 1.63; 95% confidence interval [CI]: 1.41-1.88), vulvar cancer (IRR = 1.61; 95% CI: 1.36-1.91) and vaginal cancer (IRR = 1.79; 95% CI: 1.27-1.91) than women without diabetes. Similar patterns were observed for anal IN2/3, anal cancer and cervical cancer, although not statistically significant. In contrast, women with diabetes had lower rates of cervical IN2/3 (IRR = 0.74; 95% CI: 0.69-0.79) than women without diabetes. Patterns were generally similar in women with T1D and T2D, although cancer rates were higher in women with T2D. In conclusion, the incidence of most anogenital precancers and cancers were increased in women with diabetes. However, women with diabetes had lower incidence of cervical precancer. Our findings could be explained by biological mechanisms and/or behavioral factors, such as smoking and less frequent cervical screening participation.

Abstract
OBJECTIVE The few studies on the association between benign ovarian tumors and endometrial cancer have been inconclusive. Using data from a large Danish register-based cohort study, we assessed the overall and type-specific risk of endometrial cancer among women with a benign ovarian tumor. METHODS We identified all Danish women diagnosed with a benign ovarian tumor during 1978-2016 in the Danish National Patient Register (n = 149,807). The study population was followed for subsequent development of endometrial cancer by linkage to the Danish Cancer Register and standardized incidence ratios (SIRs) with corresponding 95% confidence intervals (CIs) were calculated after correction for hysterectomy. RESULTS After a one-year delayed study entry, women with benign ovarian tumors had a decreased incidence of endometrial cancer (SIR = 0.74, 95% CI: 0.68-0.81) compared with women in the general Danish population. Both solid benign ovarian tumors (SIR = 0.79, 95% CI 0.70-0.88) and cystic benign ovarian tumors (SIR = 0.68, 95% CI 0.58-0.78) were associated with decreased incidences of endometrial cancer. Likewise, women with benign ovarian tumors had decreased incidences of both type I and type II endometrial cancer. The incidence of endometrial cancer was decreased to virtually the same magnitude irrespective of the age at diagnosis of a benign ovarian tumor and the reduction persisted throughout the follow-up period. CONCLUSIONS The risk of endometrial cancer was decreased beyond the first year after a benign ovarian tumor and the decrease persisted for 20 or more years. The possible underlying mechanisms are not known and should be investigated further.

Abstract
INTRODUCTION The optimal clinical management of women diagnosed with low-grade squamous intraepithelial lesions (LSIL) during cervical cancer screening remains unclear. In this prospective cohort study, we compared the clinical performance of two human papillomavirus (HPV) mRNA tests for triage of women with LSIL in Denmark. MATERIAL AND METHODS In a nationwide pathology register, we identified women aged 23-65 years with LSIL during 2008-2012. We included women tested for HPV mRNA with the PreTect HPV Proofer test for five high-risk HPV types (n = 2176) or the Aptima assay for 14 high-risk HPV types (n = 426). Subsequent histological diagnoses of cervical intraepithelial neoplasia grades 2, 3 or cancer (CIN2+) were identified in the register. We calculated the sensitivity and specificity for CIN2+ at 18 and 36 months of follow up, and the cumulative incidence of CIN2+ among women testing positive and negative, overall and by age (23-29, 30-39, 40-65 years). RESULTS The proportion of women with a positive mRNA test at baseline was higher in women tested with Aptima (66.7%) than in women tested with Proofer (42.8%). After 18 months, Aptima had higher sensitivity for CIN2+ than Proofer (98% [95% CI 94% to 100%] vs 85% [95% CI 82% to 88%]), whereas Proofer showed higher specificity than Aptima (67% [95% CI 64% to 70%]) vs (40% [95% CI 33% to 46%]). Aptima had particularly low specificity in women aged <40 years (23-29: 19% [95% CI 5% to 36%]; 30-39: 10% [95% CI 0% to 33%]). The 36-month cumulative incidence of CIN2+ was higher in Proofer positive (54.3% [95% CI 50.9% to 57.8%]) than in Aptima positive women (37.6% [95% CI 31.2% to 44.8%]). In women with a negative mRNA test, the 36-month cumulative incidences of CIN2+ were 13.1% (95% CI 10.8% to 15.8%) and 5.9% (95% CI 1.7% to 19.0%) for Proofer and Aptima, respectively. CONCLUSIONS In women with LSIL, Aptima had high sensitivity for CIN2+, but low specificity, especially in women aged <40 years. The Proofer test may be useful to limit immediate colposcopy referrals in younger women with LSIL, but given its low sensitivity and negative predictive value, Proofer negative women must be followed with repeat cytology.

Abstract
OBJECTIVE Use of antibiotics in critically ill patients may increase the risk of invasive Candida infection. The objective of this study was to determine whether increased exposure to antibiotics is associated with increased prevalence of invasive Candida infection. DESIGN Substudy using data from a randomized controlled trial, the Procalcitonin And Survival Study 2006-2010. SETTING Nine multidisciplinary ICUs across Denmark. PATIENTS A total of 1,200 critically ill patients. INTERVENTION Patients were randomly allocated to either a "high exposure" antibiotic therapy (intervention arm, n = 604) or a "standard exposure" guided by current guidelines (n = 596). MEASUREMENTS AND MAIN RESULTS Seventy-four patients met the endpoint, "invasive Candida infection," 40 in the high exposure arm and 34 in standard exposure arm (relative risk = 1.2; 95% CI, 0.7-1.8; p = 0.52). Among medical patients in the high exposure arm, the use of ciprofloxacin and piperacillin/tazobactam was 51% and 75% higher than in the standard exposure arm; no difference in antibiotic exposure was observed between the randomized arms in surgical patients. Among medical intensive care patients, invasive Candida infection was more frequent in the high exposure arm (6.2%; 27/437) than in standard exposure arm (3.3%; 14/424) (hazard ratio = 1.9; 95% CI, 1.0-3.6; p = 0.05). Ciprofloxacin used at study entry independently predicted invasive Candida infection (adjusted hazard ratio = 2.1 [1.1-4.1]); the risk gradually increased with duration of ciprofloxacin therapy: six of 384 in patients not exposed (1.6%), eight of 212 (3.8%) when used for 1-2 days (hazard ratio = 2.5; 95% CI, 0.9-7.3), and 31 of 493 (6.3%) when used for 3 days (hazard ratio = 3.8; 95% CI, 1.6-9.3; p = 0.002). Patients with any ciprofloxacin-containing antibiotic regimen the first 3 days in the trial had a higher risk of invasive Candida infection than did patients on any antibiotic regimen not containing ciprofloxacin (unadjusted hazard ratio = 3.7; 95% CI, 1.6-8.7; p = 0.003; adjusted hazard ratio, 3.4; 95% CI, 1.4-8.0; p = 0.006). CONCLUSIONS High exposure to antibiotics is associated to increased risk of invasive Candida infection in medical intensive care patients. Patients with ciprofloxacin-containing regimens had higher risk of invasive Candida infection. Other antibiotics, such as meropenem, piperacillin/tazobactam, and cefuroxime, were not associated with such a risk.
