Psychosocial and sexual health among men with and without HIV who have sex with men: A cross-sectional nationwide study in Denmark.

OBJECTIVES: The HIV/AIDS epidemic has disproportionately affected men who have sex with men (MSM) since its onset. Despite important medical advancements in treatment, the enduring effects of living with HIV continue to adversely impact the health and well-being of this population. This cross-sectional nationwide study examined psychosocial and sexual health among MSM in Denmark, comparing those living with and without HIV. METHODS: Data from MSM living with HIV were collected from the SHARE study, a Danish nationwide survey that investigated psychosocial, sexual and reproductive health among people with HIV, and compared with data from MSM without HIV, retrieved from the nationally representative cohort study, Project SEXUS. Associations between HIV status and psychosocial and sexual health outcomes were examined using logistic regression models while controlling for potentially confounding variables. RESULTS: Among 369 MSM with HIV and 1002 MSM without HIV, logistic regression analyses revealed that living with HIV was significantly associated with having current symptoms of anxiety and depression and greater dissatisfaction with one's body. Additionally, MSM with HIV significantly more often than MSM without HIV reported low sexual desire, sexual inactivity, a lack of sexual needs in the last year and erectile dysfunction. Having received payment for sex was more frequently reported by MSM with HIV, as was sexualised drug use, including chemsex drugs. CONCLUSION: Compared with MSM without HIV, MSM with HIV in Denmark report a higher burden of mental health and sex life challenges.

Use of intensive care, intracranial pressure monitoring, and external ventricular drainage devises in patients with bacterial meningitis, a cohort study.

BACKGROUND: Bacterial meningitis can cause a life-threatening increase in intracranial pressure (ICP). ICP-targeted treatment including an ICP monitoring device and external ventricular drainage (EVD) may improve outcomes but is also associated with the risk of complications. The frequency of use and complications related to ICP monitoring devices and EVDs among patients with bacterial meningitis remain unknown. We aimed to investigate the use of ICP monitoring devices and EVDs in patients with bacterial meningitis including frequency of increased ICP, drainage of cerebrospinal fluid (CSF), and complications associated with the insertion of ICP monitoring and external ventricular drain (EVD) in patients with bacterial meningitis. METHOD: In a single-center prospective cohort study (2017-2021), we examined the frequency of use and complications of ICP-monitoring devices and EVDs in adult patients with bacterial meningitis. RESULTS: We identified 108 patients with bacterial meningitis admitted during the study period. Of these, 60 were admitted to the intensive care unit (ICU), and 47 received an intracranial device (only ICP monitoring device N = 16; EVD N = 31). An ICP > 20 mmHg was observed in 8 patients at insertion, and in 21 patients (44%) at any time in the ICU. Cerebrospinal fluid (CSF) was drained in 24 cases (51%). Severe complications (intracranial hemorrhage) related to the device occurred in two patients, but one had a relative contraindication to receiving a device. CONCLUSIONS: Approximately half of the patients with bacterial meningitis needed intensive care and 47 had an intracranial device inserted. While some had conservatively correctable ICP, the majority needed CSF drainage. However, two patients experienced serious adverse events related to the device, potentially contributing to death. Our study highlights that the incremental value of ICP measurement and EVD in managing of bacterial meningitis requires further research.

Risk of Depression in People With Human Immunodeficiency Virus: A Nationwide Population-based Matched Cohort Study.

BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with depression. However, previous studies have not addressed familial factors. METHODS: Nationwide, population-based, matched cohort study of people with HIV (PWH) in Denmark between 1995 and 2021 who were matched on sex and date of birth with a comparison cohort randomly selected from the Danish population. Family-related factors were examined by inclusion of siblings of those in the cohorts. We calculated hazard ratios (HRs) for depression, receipt of antidepressants, electroconvulsive therapy (ECT), and suicide, as well as the yearly proportions of study cohorts with psychiatric hospital contact due to depression and receipt of antidepressants from 10 years before to 10 years after study inclusion. RESULTS: We included 5943 PWH and 59 430 comparison cohort members. Median age was 38 years, and 25% were women. We observed an increased risk of depression, receipt of antidepressants, ECT, and suicide among PWH in the 2 first years of observation (HR, 3.3; 95% confidence interval [CI]: 2.5-4.4), HR, 3.0 (95% CI: 2.7-3.4), HR, 2.8 (95% CI: .9-8.6), and HR, 10.7 (95% CI: 5.2-22.2), thereafter the risk subsided but remained increased. The proportions of PWH with psychiatric hospital contact due to depression and receipt of antidepressants were increased prior to and especially after HIV diagnosis. Risk of all outcomes was substantially lower among siblings of PWH than among PWH (HR for receipt of antidepressants, 1.1; 95% CI: 1.0-1.2). CONCLUSIONS: PWH have an increased risk of depression. Family-related factors are unlikely to explain this risk.

Incidence of Childbirth, Pregnancy, Spontaneous Abortion, and Induced Abortion Among Women With Human Immunodeficiency Virus in a Nationwide Matched Cohort Study.

BACKGROUND: Reproductive health in women with human immunodeficiency virus (HIV) (WWH) has improved in recent decades. We aimed to investigate incidences of childbirth, pregnancy, spontaneous abortion, and induced abortion among WWH in a nationwide, population-based, matched cohort study. METHODS: We included all WWH aged 20-40 years treated at an HIV healthcare center in Denmark from 1995 to 2021 and a matched comparison cohort of women from the general population (WGP). We calculated incidence rates per 1000 person-years and used Poisson regression to calculate adjusted incidence rate ratios (aIRRs) of childbirth, pregnancy, spontaneous abortion, and induced abortion stratified according to calendar periods (1995-2001, 2002-2008, and 2009-2021). RESULTS: We included 1288 WWH and 12 880 WGP; 46% of WWH were of African origin, compared with 1% of WGP. Compared with WGP, WWH had a decreased incidence of childbirth (aIRR, 0.6 [95% confidence interval, .6-.7]), no difference in the incidence of pregnancy (0.9 [.8-1.0]) or spontaneous abortion (0.9 [.8-1.0]), but an increased incidence of induced abortion (1.9 [1.6-2.1]) from 1995 to 2021. The aIRRs for childbirth, pregnancy, and spontaneous abortion increased from 1995-2000 to 2009-2021, while the aIRR for induced abortion remained increased across all time periods for WWH. CONCLUSIONS: From 1995 to 2008, the incidences of childbirth, pregnancy, and spontaneous abortion were decreased among WWH compared with WGP. From 2009 to 2021, the incidence of childbirth, pregnancy, and spontaneous abortion no longer differed among WWH compared with WGP. The incidence of induced abortions remains increased compared with WGP.

Cerebral abscesses with odontogenic origin: a population-based cohort study.

OBJECTIVES: Recent studies have indicated that cerebral abscess (CA) patients with odontogenic origin are on the rise. However, CA patients are often poorly characterized and with an unknown etiologic background. The purpose of this study is to identify and characterize CA patients that may have an odontogenic origin based on microbiologic, radiographic, and/or clinical findings. MATERIALS AND METHODS: This is a population-based cohort study analyzing retrospective and prospective data from CA patients. Radiographic examinations of panoramic radiographs (PRs) or computed tomography (CT) scans were conducted. CA patients characterized with odontogenic origin required the fulfilment of the following criteria on admission: (1) Oral pathologic conditions were the only bacterial infections present, (2) oral microorganisms were isolated in the purulent exudate from the brain, and (3) radiographically and/or clinical recordings of oral pathologic conditions. RESULTS: A total of 44 patients could be included in this study of which 25 (57%) were characterized as having CA with a likely odontogenic origin. Type two diabetes (T2D) (p = 0.014) and microorganisms of the Streptococcus anginosus group (SAG) (p < 0.01) were overrepresented in patients with CAs of odontogenic origin. CONCLUSIONS: Odontogenic infections may cause CAs to a greater extent than previously assumed. T2D was overrepresented among patients with odontogenic CA. When microorganisms of the SAG were isolated from the brain pus, CA patients had a predisposing odontogenic or sinus infection. CLINICAL RELEVANCE: The identification of patients with a likely odontogenic CA will contribute to understanding the etiology of the infectious disease and highlighting the importance of preserving oral health.

Incidence of Chronic Obstructive Pulmonary Disease in People With Human Immunodeficiency Virus and Their Parents and Siblings in Denmark.

BACKGROUND: People with human immunodeficiency virus (PWH) may be at increased risk of several respiratory syndromes including chronic obstructive pulmonary disease (COPD). In matched cohort studies, we examined risk factors for COPD in PWH and their parents and siblings compared with population controls. METHODS: Using data from national registries, competing risk regression models were constructed and used to calculate adjusted hazard ratios (aHRs) for COPD. We evaluated the effect of human immunodeficiency virus characteristics, smoking, and educational attainment on COPD incidence in PWH. RESULTS: A total of 226 PWH and 1029 population controls were diagnosed with COPD during 63 661 and 562 171 person-years of follow-up. PWH had increased risk of being diagnosed with COPD compared to controls (aHR, 2.02 [95% confidence interval, 1.75-2.33]). Parents and siblings of PWH were also more likely to be diagnosed with COPD compared to controls. CD4+ T-cell counts were not associated with COPD, but unsuppressed viral replication, smoking status, and educational attainment were associated with COPD in PWH. No COPD diagnoses were registered in PWH with high educational attainment and absence of smoking. CONCLUSIONS: PWH have an increased risk of being diagnosed with COPD, as have their parents and siblings. This seems to be driven primarily by smoking and low socioeconomic status.

Characteristics and Long-term Prognosis of Danish Patients With Varicella Zoster Virus Detected in Cerebrospinal Fluid Compared With the Background Population.

BACKGROUND: Risk factors for, and long-term outcomes following, detection of varicella zoster virus (VZV) DNA in the cerebrospinal fluid (CSF) are unknown. METHODS: We performed a nationwide population-based cohort study of all Danish residents who had VZV DNA detected in the CSF by polymerase chain reaction (PCR) between 1 January 1997 and 1 March 2016 (VZV cohort; n = 517) and an age- and sex- matched comparison cohort from the general Danish population (n = 9823). We examined potential risk factors and mortality, neurologic morbidity, psychiatric morbidity, redemptiom of prescriptions for nervous system medicine prescribed for the nervous system, and social outcomes. RESULTS: Prior hospital admission, redemption of immunosuppressive medicine, comorbidity, and immunosuppressive conditions were associated with detection of VZV DNA in the CSF. Mortality was increased in the VZV cohort, especially during the first year of observation and among patients with encephalitis. Patients in the VZV cohort had an increased risk of dementia and epilepsy. The redemption of antiepileptics and antidepressants was increased in the VZV cohort. CONCLUSIONS: Immunosuppression and comorbidity are associated with increased risk of detection of VZV DNA in the CSF and the condition is associated with increased mortality and neurological morbidity.

Long-Term Survival, Health, Social Functioning, and Education in Patients With an Enterovirus Central Nervous System Infection, Denmark, 1997-2016.

BACKGROUND: The long-term clinical course of patients with an enterovirus central nervous system infection (ECI) is poorly understood. METHODS: We performed a nationwide population-based cohort study of all Danish patients with ECI diagnosed 1997-2016 (n = 1745) and a comparison cohort from the general population individually matched on date of birth and sex (n = 17 450). Outcomes were categorized into mortality and risk of cancer and likely measures of neurological sequelae: neuropsychiatric morbidities, educational landmarks, use of hospital services, employment, receipt of disability pension, income, number of sick leave days, and nursing home residency. RESULTS: Mortality in the first year was higher among patients with ECI (mortality rate ratio [MRR] = 10.0; 95% confidence interval [CI], 4.17-24.1), but thereafter mortality was not higher (MMR = 0.94; 95% CI, 0.47-1.86). Long-term outcomes for patients with ECI were not inferior to those of the comparison cohort for risk of cancer, epilepsy, mental and behavioral disorders, dementia, depression, school start, school marks, high school education, use of hospital services, employment, receipt of disability pension, income, days of sick leave, or nursing home residency. CONCLUSIONS: Diagnosis of an ECI had no substantial impact on long-term survival, health, or social/educational functioning.

Risk of Neurological Disorders in Patients With European Lyme Neuroborreliosis: A Nationwide, Population-Based Cohort Study.

BACKGROUND: Lyme neuroborreliosis (LNB), caused by the tick-borne spirochetes of the Borrelia burgdorferi sensu lato species complex, has been suggested to be associated with a range of neurological disorders. In a nationwide, population-based cohort study, we examined the associations between LNB and dementia, Alzheimer's disease, Parkinson's disease, motor neuron disease, epilepsy, and Guillain-Barré syndrome. METHODS: We used national registers to identify all Danish residents diagnosed during 1986-2016 with LNB (n = 2067), created a gender- and age-matched comparison cohort from the general population (n = 20 670), and calculated risk estimates and hazard ratios. RESULTS: We observed no long-term increased risks of dementia, Alzheimer's disease, Parkinson's disease, motor neuron diseases, or epilepsy. However, within the first year, 8 (0.4%) of the LNB patients developed epilepsy, compared with 20 (0.1%) of the comparison cohort (difference, 0.3%; 95% confidence interval, .02-.6%). In the LNB group, 11 (0.5%) patients were diagnosed with Guillain-Barré syndrome within the first year after LNB diagnosis, compared with 0 (0.0%) in the comparison cohort. After the first year, the risk of Guillain-Barré was not increased. CONCLUSIONS: LNB patients did not have increased long-term risks of dementia, Alzheimer's disease, Parkinson's disease, motor neuron diseases, epilepsy, or Guillain-Barré. Although the absolute risk is low, LNB patients might have an increased short-term risk of epilepsy and Guillain-Barré syndrome.

Liver mortality attributable to chronic hepatitis C virus infection in Denmark and Scotland--using spontaneous resolvers as the benchmark comparator.

UNLABELLED: Liver mortality among individuals with chronic hepatitis C (CHC) infection is common, but the relative contribution of CHC per se versus adverse health behaviors is uncertain. We explored data on spontaneous resolvers of hepatitis C virus (HCV) as a benchmark group to uncover the independent contribution of CHC on liver mortality. Using national HCV diagnosis and mortality registers from Denmark and Scotland, we calculated the liver mortality rate (LMR) for persons diagnosed with CHC infection (LMRchronic ) and spontaneously resolved infection (LMRresolved ), according to subgroups defined by age, sex, and drug use. Through these mortality rates, we determined subgroup-specific attributable fractions (AFs), defined as (LMRchronic - LMRresolved )/LMRchronic , and then calculated the total attributable fraction (TAF) as a weighted average of these AFs. Thus, the TAF represents the overall fraction (where 0.00 = not attributable at all; and 1.00 = entirely attributable) of liver mortality attributable to CHC in the diagnosed population. Our cohort comprised 7,005 and 21,729 persons diagnosed with HCV antibodies in Denmark and Scotland, respectively. Mean follow-up duration was 6.3-6.9 years. The TAF increased stepwise with age. It was lowest for death occurring at <45 years of age (0.21 in Denmark; 0.26 in Scotland), higher for death occurring at 45-59 years (0.69 in Denmark; 0.69 in Scotland), and highest for death at 60+years (0.92 in Denmark; 0.75 in Scotland). Overall, the TAF was 0.66 (95% confidence interval [CI]: 0.55-0.78) in Denmark and 0.55 (95% CI: 0.44-0.66) in Scotland. CONCLUSIONS: In Denmark and Scotland, the majority of liver death in the CHC-diagnosed population can be attributed to CHC-nevertheless, an appreciable fraction cannot, cautioning that liver mortality in this population is a compound problem that can be reduced, but not solved, through antiviral therapy alone.

Association Between Educational Level and Risk of Cancer in HIV-infected Individuals and the Background Population: Population-based Cohort Study 1995-2011.

BACKGROUND: Human immunodeficiency virus (HIV)-infected individuals have increased risk of cancer. To our knowledge, no previous study has examined the impact of socioeconomic position on risk and prognosis of cancer in HIV infection. METHODS: Population-based cohort-study, including HIV-infected individuals diagnosed (without intravenous drug abuse or hepatitis C infection) (n = 3205), and a background population cohort matched by age, gender, and country of birth (n = 22 435) were analyzed. Educational level (low or high) and cancer events were identified in Danish national registers. Cumulative incidences, incidence rate ratios (IRRs), and survival using Kaplan-Meier methods were estimated. RESULTS: Low educational level was associated with increased risk of cancer among HIV-infected individuals compared to population controls: all (adjusted-IRRs: 1.4 [95% confidence interval {CI}, 1.1-1.7] vs 1.1 [95% CI, .9-1.2]), tobacco- and alcohol-related (2.1 [95% CI, 1.3-3.4] vs 1.3 [95% CI, 1.1-1.6]), and other (1.7 [95% CI, 1.1-2.8] vs 0.9 [95% CI, .7-1.0]). Educational level was not associated with infection-related or ill-defined cancers. One-year-survival was not associated with educational level, but HIV-infected individuals with low educational level had lower 5-year-survival following infection-related and ill-defined cancers. CONCLUSIONS: Education is associated with risk and prognosis of some cancers in HIV infection, and diverges from what is observed in the background population.

Unexpected Diagnosis of Cerebral Toxoplasmosis by 16S and D2 Large-Subunit Ribosomal DNA PCR and Sequencing.

The protozoan parasite Toxoplasma gondii causes severe opportunistic infections. Here, we report an unexpected diagnosis of cerebral toxoplasmosis. T. gondii was diagnosed by 16S and D2 large-subunit (LSU) ribosomal DNA (rDNA) sequencing of a cerebral biopsy specimen and confirmed by T. gondii-specific PCR and immunohistochemistry. The patient was later diagnosed with HIV/AIDS.

Cancer risk and temporal trends in people with HIV during a quarter of a century - a nationwide population-based matched cohort study.

BACKGROUND: It is important to understand current trends in cancer risk among people living with HIV (PLWH) to improve outcomes and to commission and delivery appropriate services. METHODS: Nationwide, population-based, matched cohort study on all adult PLWH treated at Danish HIV health care centres since 1 January 1995 and a comparison cohort, randomly selected from the background population and matched on sex and date of birth. RESULTS: We included 6327 PLWH and 63,270 individuals in the comparison cohort - 74% were men and median age was 37 (interquartile range: 30-46). For both smoking related cancers, virological cancers and other cancers, incidence was substantially higher in the first year of observation for PLWH than for the remaining observation period. The risk of smoking related cancer remained stably increased throughout the observation period, whereas the relative risk of virological cancers decreased, especially in the first year of follow up. Finally, the risk of other cancers for PLWH decreased to a level below that of the background population during the study period. CONCLUSION: The fact that the risk of other cancers was probably not higher among PLWH than in the comparison cohort is encouraging, as the excess risk of virological and smoking related cancers is potentially preventable by timely treatment of HIV and smoking cessation.

Outcomes following severe acute respiratory syndrome coronavirus 2 infection among individuals with and without HIV in Denmark.

OBJECTIVE: To compare the risk of a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test and coronavirus disease 2019 (COVID-19) outcomes in people with HIV (PWH) with the general population, and estimate the association with vaccination status. DESIGN: A nationwide, population based, matched cohort study. METHODS: We included all Danish PWH ≥18 years ( n  = 5276) and an age and sex-matched general population cohort ( n  = 42 308). We used Cox regression analyses to calculate (adjusted) incidence rate ratios [(a)IRR] and further stratified and restricted the analyses. RESULTS: We observed no major difference in risk of first positive SARS-CoV-2 test [aIRR: 0.8 (95% confidence interval (CI): 0.8-0.9)], but a higher risk of first hospital contact with COVID-19 and hospitalization with severe COVID-19 for PWH vs. controls [IRR: 2.0; (1.6-2.5), 1.8 (1.4-2.3)]. Risk of first hospitalization decreased substantially in PWH with calendar time [first half of year 2022 vs. 2020 IRR: 0.3; (0.2-0.6)], whereas the risk compared to population controls remained almost twofold increased. We did not observe increased risk of death after SARS-CoV-2 infection [aIRR: 0.7 (95% CI: 0.3-2.0)]. Compared to PWH who had received two vaccines PWH who receiving a third vaccine had reduced risk of first positive SARS-CoV-2 test, death (individuals ≥60years) and hospitalization [aIRR: 0.9 (0.7-1.0); 0.2 (0.1-0.7); 0.6 (0.2-1.2)]. CONCLUSION: PWH have almost the same risk of a positive SARS-CoV-2 test as the general population. Although risk of hospital contacts and severe outcomes following SARS-CoV-2 infection is increased, the risk of death does not seem to be substantially increased. Importantly, a third vaccine is associated with reduced risk of infection, and death.

Risk of Cancer Among Sarcoidosis Patients With Biopsy-verified Nonnecrotizing Granulomatous Inflammation: Population-based Cohort Study.

OBJECTIVE: To assess the long-term risk of hematologic cancers, invasive solid tumors, and nonmelanoma skin cancer (NMSC) among sarcoidosis patients with biopsy-verified nonnecrotizing granulomatous inflammation. METHODS: We used Danish administrative registers with nationwide coverage to construct a cohort of 3892 patients with sarcoidosis and an age- and sex-matched comparison cohort of 38,920 population controls. For all patients, a biopsy demonstrating nonnecrotizing granulomatous inflammation had been obtained from the lower respiratory tract at the time of diagnosis. Study outcome was time to diagnosis of cancer. Follow-up began at time of sarcoidosis diagnosis and continued for up to 10 years. We calculated hazard ratios (HRs) as estimates of the cancer risk among the patients with sarcoidosis relative to that among the population controls and used cumulative incidence functions to calculate absolute 10-year risk estimates. RESULTS: We observed an increased long-term risk of hematologic cancers (HR during the first 2 years of follow-up: 2.71 [95% CI 1.18-6.25]; HR after > 2 years of follow-up: 2.12 [95% CI 1.29-3.47]) and NMSC (HR after > 2 years of follow-up: 1.82 [95% CI 1.43-2.32]) among the patients with sarcoidosis. An increased risk of invasive solid tumors was only observed during the first 2 years (HR 1.55, 95% CI 1.18-2.04). Compared with the population controls, the patients with sarcoidosis had an increased absolute 10-year risk of hematologic cancers (risk difference 0.56%, 95% CI 0.11-1.01%) and NMSC (risk difference 1.58%, 95% CI 0.70-2.47%). CONCLUSION: Sarcoidosis patients with biopsy-verified nonnecrotizing granulomatous inflammation have an increased long-term risk of hematologic cancers and NMSC compared with the general population.

Risk of subarachnoid haemorrhages and aneurysms in Danish people with HIV.

OBJECTIVE: It remains unclear whether people with HIV (PWH) have increased risk of aneurysms. We aimed to investigate if the risk of subarachnoid haemorrhage, cerebral aneurysm, aortic aneurysm and other arterial aneurysms and dissections is increased in PWH compared with the general population. DESIGN: We performed a nationwide population-based matched cohort study. METHODS: We compared PWH with age-matched and sex-matched comparison cohort members to calculate incidence rate ratios (IRR) of subarachnoid haemorrhage, cerebral aneurysm, aortic aneurysm and other arterial aneurysms and dissections as well as surgery for these conditions. RESULTS: We included all PWH, who were Danish residents and treated at a HIV healthcare centre between January 1995 and February 2018 ( n  = 6935) and an age-matched and sex-matched comparison cohort ( n  = 55 480). PWH had increased risk of subarachnoid haemorrhage (IRR 1.7, 95% CI, 1.1-2.6), but no increased risk of surgery for this condition. PWH had no increased risk of cerebral aneurysm or aortic aneurysm or surgery for these conditions. The risk of other arterial aneurysms and dissections was increased in PWH (IRR 2.0, 95% CI, 1.4-2.9), but this only applied for PWH who reported intravenous substance use as a route of HIV transmission (IRR 18.4, 95% CI, 9.3-36.6), and not for PWH without reported injection drug use (IRR 1.2, 95% CI, 0.73-1.7). CONCLUSION: PWH were not at an increased risk of cerebral, aortic or other arterial aneurysms and dissections. Although PWH were at an increased risk of subarachnoid haemorrhage, subarachnoid haemorrhages were rare among PWH.

Real-world Treatment Patterns and Overall Survival in Locally Advanced and Metastatic Urothelial Tract Cancer Patients Treated with Chemotherapy in Denmark in the Preimmunotherapy Era: A Nationwide, Population-based Study.

BACKGROUND: Real-world treatment patterns and survival outcomes of locally advanced, unresectable, and metastatic urinary tract cancer (mUTC) patients have not previously been studied in a nationwide, population-based cohort. OBJECTIVE: To describe treatment patterns and survival outcomes in mUTC patients treated in the real-world clinical setting. DESIGN SETTING AND PARTICIPANTS: This nationwide, population-based study included all mUTC patients initiating first-line chemotherapy at Danish oncology departments from January 2010 to March 2016. Data were retrospectively obtained from electronic medical records. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcome measurements were descriptive. Kaplan-Meier was used for survival analysis. RESULTS AND LIMITATIONS: Of 952 patients included in the study, 46.2% initiated standard gemcitabine/cisplatin (GC) and 21.1% gemcitabine/carboplatin (CaG); the remaining patients initiated other treatment regimens. Median follow-up was 11.6 mo. The overall response rate and disease control rate were 43.0% and 61.7% in all patients, 51.4% and 69.1% in GC-treated patients, and 34.4% and 58.8% in CaG-treated patients, respectively. Median overall survival (OS) was 11.7 (95% confidence interval [CI]: 10.8-12.5) mo in all patients, 14.0 (95% CI: 12.5-15.5) mo in GC-treated patients, and 9.8 (95% CI: 8.7-10.9) mo in CaG-treated patients. Limitations include the retrospective study design. CONCLUSIONS: Real-world mUTC patients are older and less fit than patients enrolled in clinical trials; despite this, tumor responses and survival are comparable. Survival in our patient cohort is also comparable with that reported from other real-world studies in this patient group. PATIENT SUMMARY: We studied treatment patterns and survival in urinary tract cancer patients receiving chemotherapy in the real-world clinical practice. Survival in our patient cohort was comparable with that reported from clinical trials and other real-world studies in this patient group.

Assessment of the Risk of Psychiatric Disorders, Use of Psychiatric Hospitals, and Receipt of Psychiatric Medication Among Patients With Lyme Neuroborreliosis in Denmark.

Importance: The association of Lyme neuroborreliosis with the development of psychiatric disease is unknown and remains a subject of debate. Objective: To investigate the risk of psychiatric disease, the percentage of psychiatric hospital inpatient and outpatient contacts, and the receipt of prescribed psychiatric medications among patients with Lyme neuroborreliosis compared with individuals in a matched comparison cohort. Design, Setting, and Participants: This nationwide population-based matched cohort study included all residents of Denmark who received a positive result on an intrathecal antibody index test for Borrelia burgdorferi (patient cohort) between January 1, 1995, and December 31, 2015. Patients were matched by age and sex to a comparison cohort of individuals without Lyme neuroborreliosis from the general population of Denmark. Data were analyzed from February 2019 to March 2020. Exposures: Diagnosis of Lyme neuroborreliosis, defined as a positive result on an intrathecal antibody index test for B burgdorferi. Main Outcomes and Measures: The 0- to 15-year hazard ratios for the assignment of psychiatric diagnostic codes, the difference in the percentage of psychiatric inpatient and outpatient hospital contacts, and the difference in the percentage of prescribed psychiatric medications received among the patient cohort vs the comparison cohort. Results: Among 2897 patients with Lyme neuroborreliosis (1646 men [56.8%]) and 28 970 individuals in the matched comparison cohort (16 460 men [56.8%]), the median age was 45.7 years (interquartile range [IQR], 11.5-62.0 years) for both groups. The risk of a psychiatric disease diagnosis and the percentage of hospital contacts for psychiatric disease were not higher among patients with Lyme neuroborreliosis compared with individuals in the comparison cohort. A higher percentage of patients with Lyme neuroborreliosis compared with individuals in the comparison cohort received anxiolytic (7.2% vs 4.7%; difference, 2.6%; 95% CI, 1.6%-3.5%), hypnotic and sedative (11.0% vs 5.3%; difference, 5.7%; 95% CI, 4.5%-6.8%), and antidepressant (11.4% vs 6.0%; difference, 5.4%; 95% CI, 4.3%-6.6%) medications within the first year after diagnosis, after which the receipt of psychiatric medication returned to the same level as the comparison cohort. Conclusions and Relevance: In this population-based matched cohort study, patients with Lyme neuroborreliosis did not have an increased risk of developing psychiatric diseases that required hospital care or treatment with prescription medication. The increased receipt of psychiatric medication among patients with Lyme neuroborreliosis within the first year after diagnosis, but not thereafter, suggests that most symptoms associated with the diagnosis subside within a short period.

Risk of myocardial infarction in parents of HIV-infected Individuals: a population-based Cohort Study.

BACKGROUND: Previous studies have indicated an increased risk of myocardial infarction (MI) in HIV infected individuals especially after start of highly active antiretroviral therapy (HAART). It is however controversial whether the increased risk of atherosclerotic disease is exclusively associated with the HIV disease and HAART or whether life-style related or genetic factors also increase the risk in this population. To establish whether the increased risk of myocardial infarction in HIV patients partly reflects an increased risk of MI in their families, we estimated the relative risk of MI in parents of HIV-infected individuals. METHODS: From the Danish HIV Cohort Study and the Danish Civil Registration System we identified the parents of all HIV-infected patients born in Denmark after 1952 in whom a Danish born mother was identifiable. For each HIV patient, 4 matched population controls and their parents were identified. Cumulative incidence functions were constructed to illustrate time to first MI of the parents as registered in the Danish National Hospital Registry. Incidence rate ratios (IRR) were estimated by Cox's regression analyses. Due to the confidential type of the analysed data the study was approved by the Danish Data Protection Agency. RESULTS: 2,269 mothers and 2,022 fathers of HIV patients as well as 9,076 mothers and 8,460 fathers of control subjects were identified. We observed an increased risk of MI in mothers of HIV patients (adjusted IRR, 1.31; 95% CI: 1.08-1.60). The strongest association was seen in case the offspring was infected heterosexually (adjusted IRR, 1.59; 95% CI: 1.07-2.35) or by IV drug abuse (IVD) (adjusted IRR, 1.63; 95% CI: 1.02-2.60). In fathers of HIV patients the risk of MI was only increased if the offspring was infected by IVD (adjusted IRR, 1.42; 95% CI: 1.01-2.00). CONCLUSION: Mothers of HIV-infected patients have an increased risk of MI. We presume that this stems from family related life style risk factors, some of which may also influence the risk of MI in HIV-infected patients.
