Comparative epidemiology of bacteraemia in two ageing populations: Singapore and Denmark.

Burden of bacteraemia is rising due to increased average life expectancy in developed countries. This study aimed to compare the epidemiology and outcomes of bacteraemia in two similarly ageing populations with different ethnicities in Singapore and Denmark. Historical cohorts from the second largest acute-care hospital in Singapore and in the hospitals of two Danish regions included patients aged 15 and above who were admitted from 1 January 2006 to 31 December 2016 with at least 1 day of hospital stay and a pathogenic organism identified. Among 13 144 and 39 073 bacteraemia patients from Singapore and Denmark, similar 30-day mortality rates (16.5%; 20.3%), length of hospital stay (median 14 (IQR: 9-28) days; 11 (6-21)), and admission rate to ICU (15.5%; 15.6%) were observed, respectively. Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus ranked among the top four in both countries. However, Singaporeans had a higher proportion of patients with diabetes (46.8%) and renal disease (29.5%) than the Danes (28.0% and 13.7%, respectively), whilst the Danes had a higher proportion of patients with chronic pulmonary disease (18.0%) and malignancy (35.3%) than Singaporeans (9.7% and 16.2%, respectively). Our study showed that top four causative organisms and clinical outcomes were similar between the two cohorts despite pre-existing comorbidities differed.

Hysterectomy on benign indication and risk of pelvic organ prolapse surgery: A national matched cohort study.

INTRODUCTION: Hysterectomy is a frequently performed gynecological procedure but long-term effects remain understudied. Pelvic organ prolapse reduces life quality significantly. The lifetime risk of undergoing pelvic organ prolapse surgery is 20% and parity is known to be the largest risk factor. Studies have shown an increased risk of pelvic organ prolapse surgery after hysterectomy; however, few have studied the compartments which are affected and how this association is affected by surgical route and parity. MATERIAL AND METHODS: In this Danish nationwide cohort study, we identified women born in 1947-2000 who underwent hysterectomy during 1977-2018 who were indexed on the day of hysterectomy. We excluded women who immigrated when older than 15 years, who underwent pelvic organ prolapse surgery prior to index, and who were diagnosed with a gynecological cancer prior to or within 30 days of index. Women who underwent hysterectomy were matched 1:5 to references on age and year of hysterectomy. Women were censored at the time of death, emigration, a gynecological cancer diagnosis, radical or unspecified hysterectomy or December 31, 2018, whichever came first. The risk of pelvic organ prolapse surgery after hysterectomy was computed using Cox proportional hazard ratios (HRs) with 95% confidence intervals (CIs), adjusted for age, calendar year, parity, income and educational level. RESULTS: We included 80 444 women who underwent hysterectomy and 396 303 reference women. Women who underwent hysterectomy had a significantly higher risk of undergoing pelvic organ prolapse surgery: HRadjusted  1.4 (95% CI 1.3-1.5). In particular, the risk of a posterior compartment prolapse operation was increased: HRadjusted 2.2 (95% CI 2.0-2.3). The risk of prolapse surgery increased with increased parity and by an additional 40% after hysterectomy. Cesarean sections did not seem to increase the risk of prolapse surgery. CONCLUSIONS: This study shows that hysterectomy, regardless of surgical route, leads to an increased risk of pelvic organ prolapse surgery, especially in the posterior compartment. The risk of prolapse surgery increased with the number of vaginal births, and not cesarean sections. Women should be thoroughly informed about the risk of pelvic organ prolapse and other treatment options should be considered before choosing hysterectomy to treat benign gynecological diseases -particularly women who have had numerous vaginal births.

All-cause Mortality Due to Bacteremia during a 60-Day Non-Physician Healthcare Worker Strike.

This study explored all-cause mortality of bacteremia diagnosed during a 60-day non-physician healthcare worker strike in 2008. A significant change, with 5.0% (95% confidence interval [CI] 1.2-8.7%, P < .01) absolute risk increase, was seen in 90-day mortality during the strike (n = 598) compared with the rest of the study period 2000-2015 (n = 75 647).

Longitudinal trajectory patterns of plasma albumin and C-reactive protein levels around diagnosis, relapse, bacteraemia, and death of acute myeloid leukaemia patients.

BACKGROUND: No study has evaluated C-reactive protein (CRP) and plasma albumin (PA) levels longitudinally in patients with acute myeloid leukaemia (AML). METHODS: We studied defined events in 818 adult patients with AML in relation to 60,209 CRP and PA measures. We investigated correlations between CRP and PA levels and daily CRP and PA levels in relation to AML diagnosis, AML relapse, or bacteraemia (all ±30 days), and death (─30-0 days). RESULTS: On the AML diagnosis date (D0), CRP levels increased with higher WHO performance score (PS), e.g. patients with PS 3/4 had 68.1 mg/L higher CRP compared to patients with PS 0, adjusted for relevant covariates. On D0, the PA level declined with increasing PS, e.g. PS 3/4 had 7.54 g/L lower adjusted PA compared to PS 0. CRP and PA levels were inversely correlated for the PA interval 25-55 g/L (R = - 0.51, p < 10-5), but not for ≤24 g/L (R = 0.01, p = 0.57). CRP increases and PA decreases were seen prior to bacteraemia and death, whereas no changes occurred up to AML diagnosis or relapse. CRP increases and PA decreases were also found frequently in individuals, unrelated to a pre-specified event. CONCLUSIONS: PA decrease is an important biomarker for imminent bacteraemia in adult patients with AML.

A Danish national population-based cohort study of synthetic midurethral slings, 2007-2011.

INTRODUCTION AND HYPOTHESIS: Synthetic midurethral slings (MUSs) have shown similar cure rates in several short- and medium-term follow-up studies. Recently, long-term follow-up studies have indicated that the cure rate is higher following the retropubic midurethral sling (RPMUS) compared with the transobturator midurethral sling (TOMUS) procedure. The aim was to evaluate the efficacy of synthetic MUSs and to examine the influence of department and surgeon volume and patient-related factors on the cure rate of synthetic MUSs. METHODS: A retrospective cohort study based on a national population over a 5-year period (2007-2011) using data from the Danish Urogynaecological Database (DugaBase). RESULTS: A total of 4519 women with first-time MUS were registered in the DugaBase. Cure was achieved in 1242/1639 (75.78%) at a 3-month follow-up. RPMUSs were more frequently in use in high-volume departments compared with the other departments and more often implanted by high- than low-volume surgeons. Women treated by a medium- (adjusted OR 1.82; 95% CI 1.01-3.28, "frequency") or high-volume surgeon (1.98; 1.18-3.32, "frequency") had an increased probability of cure compared with women treated by a low-volume surgeon. The difference was only significant for women who received a TOMUS. CONCLUSIONS: This national population-based cohort study confirmed a high cure rate of synthetic MUSs at short-term follow-up. It is the largest study to indicate a learning curve for TOMUS. Patients were not actively involved in which synthetic MUS was to be performed as the choice of surgical option was made at the departmental level.

Asymptomatic Carriers Contribute to Nosocomial Clostridium difficile Infection: A Cohort Study of 4508 Patients.

BACKGROUND & AIMS: Nosocomial infections with Clostridium difficile present a considerable problem despite numerous attempts by health care workers to reduce risk of transmission. Asymptomatic carriers of C difficile can spread their infection to other patients. We investigated the effects of asymptomatic carriers on nosocomial C difficile infections. METHODS: We performed a population-based prospective cohort study at 2 university hospitals in Denmark, screening all patients for toxigenic C difficile in the intestine upon admittance, from October 1, 2012, to January 31, 2013. Screening results were blinded to patients, staff, and researchers. Patients were followed during their hospital stay by daily registration of wards and patient rooms. The primary outcomes were rate of C difficile infection in exposed and unexposed patients and factors associated with transmission. RESULTS: C difficile infection was detected in 2.6% of patients not exposed to carriers and in 4.6% of patients exposed to asymptomatic carriers at the ward level (odds ratio for infection if exposed to carrier, 1.79; 95% confidence interval, 1.16-2.76). Amount of exposure correlated with risk of C difficile infection, from 2.2% in the lowest quartile to 4.2% in the highest quartile of exposed patients (P = .026). Combining the load of exposure to carriers and length of stay seemed to have an additive effect on the risk of contracting C difficile. CONCLUSIONS: In a population-based prospective cohort study in Denmark, we found that asymptomatic carriers of toxigenic C difficile in hospitals increase risk of infection in other patients.

Treatment and survival of glioblastoma patients in Denmark: The Danish Neuro-Oncology Registry 2009-2014.

BACKGROUND: As many glioblastoma patients are in a poor condition they are unable to undergo the full treatment documented in clinical trials. We aimed to examine the survival and its relationship to clinical characteristics and treatment in a nationwide population of glioblastoma patients in Denmark. METHODS: We included prospectively recorded clinical data from 1364 adult patients with histologically verified glioblastoma from the Danish Neuro-Oncology Registry, 2009-2014. RESULTS: The age standardized incidence rate was 6.3/100,000 person-years for males and 3.9 for females and the median age was 66 years. The median overall survival was 11.2 months. There was an independently significant prognostic effect of age, performance status, cognitive symptoms, tumor diameter, multifocality, crossing midline, and contrast enhancement. For partial and total resection compared to biopsy only, the adjusted risk of dying was reduced by 43% (HR [CI] 0.57 [0.48-0.68]) and 51% (0.49 [0.40-0.60]), respectively. For patients receiving a partial and full radiochemotherapy regimen compared to no postsurgical treatment, the risk reduction was 56% (HR [CI] 0.44 [0.37-0.53]) and 70% (0.30 [0.25-0.35]), respectively. The full radiochemotherapy regimen was only allocated to 50% of the patients, 29% among the oldest (70+ years) and 60% among the younger (18-69 years). CONCLUSIONS: Glioblastoma patients had a poor overall survival but with several specific independent prognostic factors. Extensive cancer treatment was associated with an increasing survival in all age groups, but only half of the patients were sufficiently fit for a full regimen of postoperative combined radiochemotherapy.

Epidemiology of glioma: clinical characteristics, symptoms, and predictors of glioma patients grade I-IV in the the Danish Neuro-Oncology Registry.

In this national population-based study of glioma, we present epidemiologic data on incidence, demographics, survival, clinical characteristics and symptoms, and evaluate the association of specific indicators with the grade of glioma. We included 1930 patients registered in the Danish Neuro-Oncology Registry (DNOR) from 2009 to 2014. DNOR is a large-scale national population-based database including all adult glioma patients in Denmark. The age-adjusted annual incidence of histologic verified glioma was 7.3 cases pr. 100,000 person-years. High-grade gliomas were present in 85% and low-grade glioma in 15%. The overall male:female ratio was 3:2 and the mean age at onset was 60 years. Data for WHO grade I, II, III and IV glioma showed several important differences regarding age and sex distribution and symptomatology at presentation. The mean age increased with the grade of glioma and males predominated in all grades. Focal deficits were the most frequent presenting symptom, but among patients with glioma, grade II epileptic seizures were the most frequent symptom. Headache was a rare mono-symptomatic onset symptom. At presentation, higher age, focal deficits and cognitive change for <3 months duration, and headache <1 month were significant independent indicators of high-grade gliomas. Younger age and epileptic seizures for more than 3 months were indicative for low-grade gliomas. Survival rates for glioma grade I-IV showed decreasing survival with increasing grade. Glioma grade I-IV showed high diversity regarding several demographic and clinical characteristics emphasizing the importance of individually tailored disease treatments and support.

A national population-based cohort study of urethral injection therapy for female stress and mixed urinary incontinence: the Danish Urogynaecological Database, 2007-2011.

INTRODUCTION AND HYPOTHESIS: Urethral injection therapy (UIT) has been performed since the early 20th century and a variety of agents have been launched. In 2006, polyacrylamide hydrogel (PAGH) was introduced and is now widely used as an agent. The objective was to evaluate the efficacy of PAGH based on a national population over a 5-year period (2007-2011) and the influence of patient-related factors, surgeon experience, and department volume. METHODS: A retrospective cohort study was carried out based on data from the Danish Urogynaecological Database (DugaBase). RESULTS: A total of 731 women were registered in the DugaBase. Cure was achieved in 75 out of 252 women (29.8%) and no leakage at all in 23 out of 252 (9.1%) at the 3-month follow-up. The mean total International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score decreased from 16 (SD 3.8) to 10.6 (SD 6.2; p < 0.001). UIT was performed at 16 departments, of which four high-volume departments performed 547 out of 814 UITs (67.2%). Women with severe UI had a decreased chance of cure (all ICIQ-SF scores), as did women on antimuscarinic drugs (adjusted OR 0.14; 95%, CI 0.04-0.41 "frequency") and (adjusted OR 0.33; 95%, CI 0.13-0.82, "amount"). Women treated by a high-volume surgeon had a higher chance of cure (OR 4.51; 95% CI, 1.21-16.82, "frequency") and a lower risk of 30-day hospital contacts (OR 0.27; 95% CI 0.09-0.76). CONCLUSION: The study represented a cure for UIT among women in an everyday life setting. A surgeon learning curve for UIT was indicated, as was assigning interventions to fewer hands to improve the surgical training value and consequently the cure rate for women with UIT.

Reoperation for urinary incontinence: a nationwide cohort study, 1998-2007.

BACKGROUND: The synthetic midurethral slings were introduced in the 1990s and were rapidly replaced the Burch colposuspension as the gold standard treatment for urinary incontinence. It has been reported that the retropubic midurethral tape has an objective and subjective cure rate of 85% at 5 years of follow-up, but the rate of reoperation after retropubic midurethral tape at the long-term follow-up is less well described. The existing literature specifies an overall lifetime rate of reoperation of about 8-9% after an initial operation for urinary incontinence. There are, however, conflicting statements about the risk of reoperation after specific surgical procedures for urinary incontinence. OBJECTIVE: The objective of the study was to describe the cumulative incidence of reoperation within a 5 year period after different types of surgical procedures for urinary incontinence based on a nationwide population. STUDY DESIGN: We used the Danish National Patient Registry to identify women who had surgery for urinary incontinence from 1998 through 2007 and the outcome was a reoperation within 5 years. Kaplan-Meier curves were used to estimate the rate of reoperation for 6 types of surgery for urinary incontinence (retropubic midurethral tape, transobturator tape, urethral injection therapy, Burch colposuspension, pubovaginal slings, and miscellaneous operations). Cox proportional hazard models were used to estimate the hazard ratio (HR) with 95% confidence intervals (CIs), adjusted for factors suspected to be associated with reoperation. RESULTS: A total of 8671 women (mean age, 56.1 years, range 6.7-93.7 years) underwent surgical treatment for urinary incontinence. Among these women, 5820 (67%) received a synthetic midurethral sling at baseline. The cumulative incidence of reoperation after any surgical treatment for urinary incontinence was 10%. The lowest rate of reoperation was observed among women having pubovaginal slings (6%), retropubic midurethral tape (6%) and Burch colposuspension (6%) followed by transobturator tape (9%), and miscellaneous operations (12%), whereas the highest observed risk was for urethral injection therapy (44%). In a Cox proportional hazard model that adjusted for age, department volume, and calendar effect, the transobturator tape carried a 2-fold higher risk of reoperation (HR, 2.1; 95% CI, 1.5-2.9), and urethral injection therapy carried a 12 fold-higher risk (HR, 11.5; 95% CI, 9.3-14.3) compared with retropubic midurethral tape. CONCLUSION: This nationwide cohort study provides physicians with a representative evaluation of the rate of reoperations after surgical procedures for urinary incontinence. Pubovaginal slings, Burch colposuspension, and retropubic midurethral tape had a similar risk of reoperation (6%). Women who were operated with transobturator tape had a significantly higher risk of reoperation compared with retropubic midurethral tape.

Discrepancies between patient-reported outcome measures when assessing urinary incontinence or pelvic-prolapse surgery.

INTRODUCTION AND HYPOTHESIS: In order to assess the outcome following surgery for urinary incontinence (UI) and pelvic organ prolapse (POP) the importance of patient-reported outcome measures, in addition to the clinical objective measures, has been recognised. The International Consultation on Incontinence has initiated the development and evaluation of disease-specific questionnaires (ICIQ) to compare the patient's degree of improvement. Alternatively, the Patient's Global Impression of Improvement (PGI-I score) with an inherent before-after assessment has been widely accepted in recent studies. The aim of this study was to compare the PGI-I versus the ICIQ score for women undergoing UI or POP surgery. METHODS: This study is based on self-administered pre- and postoperative questionnaires, completed by women undergoing surgery for UI or POP in Denmark in 2013. Weighted Kappa statistics and 95 % limits of agreement method were used when comparing the PGI-I and ICIQ scores. RESULTS: Among the 3,310 women included the PGI-I score showed a higher improvement than the IQIC score, for UI 0.83 (CI 95 %: 0.80-0.85) vs 0.62 (0.60-0.64) and for POP 0.77 (0.75-0.78) vs 0.66 (0.65-0.67). CONCLUSIONS: The PGI-I score renders higher satisfaction than the ICIQ score and the PGI-I score overestimates the improvement following UI and POP surgery.

Repeat surgery after failed midurethral slings: a nationwide cohort study, 1998-2007.

INTRODUCTION AND HYPOTHESIS: The objective was to describe the choice of subsequent surgery after failure of synthetic midurethral slings (MUS) based on a nationwide background population. METHODS: We used the Danish National Patient Registry to identify women who had undergone first-time synthetic MUS from 1998 through 2007. The outcome was repeat surgery with any subsequent procedure code for urinary incontinence within a 5-year period of the first procedure. RESULTS: A total of 5,820 women (mean age 55.4 years, ± 12.1) were registered with a synthetic MUS, and 354 (6 %) underwent reoperation. The first-choice treatment for reoperation was a synthetic MUS (45.5 %) followed by urethral injection therapy (36.7 %) and miscellaneous operations (13.8 %). Pubovaginal slings (2.8 %) and Burch colposuspension (1.1 %) were seldom used. At reoperation, 289 women (82 %) were treated at the department where they had undergone their primary synthetic MUS. CONCLUSION: In this nationwide cohort study of synthetic MUS a repeat synthetic MUS was the first choice and urethral injection therapy a frequent second choice. The majority of reoperations (82 %) took place in the same department as the primary operation.

Antibiotic use from conception to diagnosis of child leukaemia as compared to the background population: A nested case-control study.

BACKGROUND: The role of infection in the aetiology of childhood leukaemia is unknown. We used prescriptions of antibiotics from Danish pharmacies as a proxy measure for the occurrence of infections. PROCEDURE: We investigated the association between exposure to antibiotics, from conception to leukaemia diagnosis, and the risk of leukaemia. Incident cases of leukaemia among children in Denmark, 1995-2008, with mothers having their earliest conception date in 1995, were individually matched to population controls by age, sex and municipality. Conditional logistic regression analyses assessed antibiotic redemptions in different time periods from conception up to 6 months before the diagnoses of all leukaemia types, acute lymphoblastic leukaemia [ALL] and ALL in 2- to 5-year-old children, adjusting for several potential confounders. RESULTS: A total of 120/360 (33.3%) leukaemia mothers and 1,081/3,509 (30.8%) control mothers redeemed antibiotics during pregnancy (P = 0.32). For children, the equivalent numbers were 276 (76.7%) and 2,665 (75.9%) (P = 0.76). Histograms of antibiotic redemptions showed no temporal differences between leukaemia mothers/children and controls, which was confirmed in adjusted regression analyses (OR [95% CI]: 1.02 [0.75-1.38]). Only antibiotics redeemed during the first year after birth differed from this (OR [95% CI] for ALL diagnosed in 2- to 5-year-old children: 0.46 [0.31-0.66]). CONCLUSIONS: In this hypothesis generating study, the similar amount and pattern of antibiotic redemptions in children with and without leukaemia indicate that infections play a minor role in the aetiology of childhood leukaemia. However, less antibiotic redemptions during the first year of life conform to Greaves' 'delayed infection hypothesis'.

The Nordic Five to Fifteen questionnaire could provide the basis for a common neurological disability variable.

AIMS: Assessing disabilities in children is essential and Danish parents provide increasingly important feedback on how their child's disability affects daily living. The Nordic Five to Fifteen (FTF) parent questionnaire is widely used in Nordic countries to detect atypical or delayed development in children. Our study evaluated its internal validity and whether it could be used to generate a common disability variable across childhood neurological disorders and severities. METHODS: The 28-statement FTF questionnaire was completed by the parents of children with spina bifida, muscular disorders, spinal atrophy, cerebral palsy, blindness, deafness, mental retardation and disability, who received treatment for brain tumours. Psychometric analysis and Rasch analysis of the five FTF code qualifier level data were carried out. RESULTS: A total of 227 of 332 (68.4%) parents participated. The mean qualifier score was 3.06 (standard deviation 0.89, range 2.31-4.26), and the variances mean was 1.57 (range 0.87-2.38). The corrected code-total correlation was 0.65, and reliability was 0.96. The Rasch analysis demonstrated good fit alignment of codes. CONCLUSION: The FTF questionnaire can be used with children with neurological disabilities, and the Rasch scale analysis results indicate that it could form the analytical basis for developing a common disability variable.

Longitudinal Measurements of Blood Biomarkers in Patients with Crohn's Disease or Ulcerative Colitis Treated with Infliximab: Only the Latest Values in the Induction Period Predict Treatment Failure.

Background: Few studies have incorporated longitudinal assessments or used combinations of blood biomarkers as predictors of loss of response to biologic therapy for patients with Crohn's disease (CD) or ulcerative colitis (UC). Methods: This is a population-based cohort study comprising Danish patients with CD or UC from 2008 to 2018. We used logistic regression to analyze whether levels and changes in levels of C-reactive protein (CRP), serum albumin, and hemoglobin, routinely measured during a 14-week infliximab induction period, predicted a change to another biologic medication or cessation of biologic therapy. Results: During the induction period, 2883 (1626 CD, 1257 UC) patients had 12,730, 12,040, and 13,538 specimens with CRP, serum albumin, and hemoglobin, respectively. In all, 284 patients (9.9%) switched to another biologic medication, and 139 (4.8%) ceased biologic therapy in the follow-up period. Only the most recent CRP and hemoglobin levels predicted the efficacy of infliximab treatment at approximately 14 weeks, a time point when the clinician often determines whether to continue treatment. Conclusion: Measurement of blood biomarkers prior to the clinical assessment does not predict the effectiveness of infliximab.

Patient reported outcome measures in women undergoing surgery for urinary incontinence and pelvic organ prolapse in Denmark, 2006-2011.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the impact of urogynecological surgery on quality of life based on patient reported outcome measures (PROMs). METHODS: Data were retrieved from the Danish Urogynaecological Database. Inclusion criteria were Danish women undergoing surgery for urinary incontinence (UI) or pelvic organ prolapse (POP) from 2006 to 2011. Using frequency of symptoms and a visual analogue scale (VAS) both pre- and postoperatively, their severity of symptoms and quality of life were measured by questionnaires. RESULTS: During the study period, 20,629 urogynecological procedures were performed. The questionnaires on severity of symptoms and the VAS had been completed both pre- and postoperatively for approximately one third of women undergoing surgery. For UI surgery, 83% had improved symptoms, 13% were unchanged, and 4% had worse symptoms postoperatively. For POP surgery, 80, 17, and 3% were improved, unchanged, and worsened, respectively. The postoperative bother of symptoms and interference in everyday life evaluated by VAS were significantly reduced for both UI [preoperative median VAS score 9, postoperative median score 1 (p < 0.001)] and POP [8 preoperatively and 0 postoperatively (p < 0.001)]. CONCLUSIONS: Based on PROMs, surgery for UI and POP is effective in alleviating symptoms associated with UI or POP, and it can improve quality of life in symptomatic women. Pre- and postoperative questionnaires are useful tools in assessing symptomatic outcome measures after surgery.

The Danish Urogynaecological Database: establishment, completeness and validity.

INTRODUCTION AND HYPOTHESIS: The Danish Urogynaecological Database (DugaBase) is a nationwide clinical database established in 2006 to monitor, ensure and improve the quality of urogynaecological surgery. We aimed to describe its establishment and completeness and to validate selected variables. This is the first study based on data from the DugaBase. METHODS: The database completeness was calculated as a comparison between urogynaecological procedures reported to the Danish National Patient Registry and to the DugaBase. Validity was assessed for selected variables from a random sample of 200 women in the DugaBase from 1 January 2009 to 31 October 2010, using medical records as a reference. RESULTS: A total of 16,509 urogynaecological procedures were registered in the DugaBase by 31 December 2010. The database completeness has increased by calendar time, from 38.2 % in 2007 to 93.2 % in 2010 for public hospitals. All medical records were retrievable for the validation study. The overall percent agreement was at least 90 % for the following variables: surgical procedure code, hospital department, date of surgery, use of antibiotic prophylaxis, prior gynaecological surgery, height, weight, parity and smoking. CONCLUSIONS: The database completeness of the DugaBase has improved over time, now with a nearly complete registration from all public hospitals in Denmark. The overall percent agreement between selected variables and medical records is high. We conclude that due to the high degree of database completeness and data of high validity the DugaBase offers a unique possibility for continuing quality assessment of urogynaecological surgery in Denmark and future research.

Interpretations of the Role of Plasma Albumin in Prognostic Indices: A Literature Review.

This review assesses how publications interpret factors that influence the serum or plasma albumin (PA) level in prognostic indices, focusing on inflammation and nutrition. On PubMed, a search for "albumin AND prognosis" yielded 23,919 results. From these records, prognostic indices were retrieved, and their names were used as search strings on PubMed. Indices found in 10 or more original research articles were included. The same search strings, restricted to "Review" or "Systematic review", retrieved yielded on the indices. The data comprised the 10 latest original research articles and up to 10 of the latest reviews. Thirty indices had 294 original research articles (6 covering two indices) and 131 reviews, most of which were from recent years. A total of 106 articles related the PA level to inflammation, and 136 related the PA level to nutrition. For the reviews, the equivalent numbers were 54 and 65. In conclusion, more publications mention the PA level as a marker of nutrition rather than inflammation. This is in contrast to several general reviews on albumin and nutritional guidelines, which state that the PA level is a marker of inflammation but not nutrition. Hypoalbuminemia should prompt clinicians to focus on the inflammatory aspects in their patients.

Detection of infections by computerized capture of peaks in longitudinally measured C-reactive protein levels.

We developed four algorithms for the automatic capture of C-reactive protein (CRP) peaks in 296 adult patients with acute myeloid leukemia who had bloodstream infection (BSI) episodes, negative blood cultures (BCs) or possible infections where no BCs were performed. The algorithms detected CRP peaks for 418-446 of the 586 documented BSI episodes (71.3-76.1%) and 2714-3118 of the 4382 negative BCs (61.9-71.2%). The four algorithms captured 382-789 CRP peaks in which there were neither BSI episodes nor negative BCs. We conclude that automatic capture of CRP peaks is a tool for the monitoring of BSI episodes and possibly other infections in patients with acute myeloid leukemia.

Impact of C-reactive protein and albumin levels on short, medium, and long term mortality in patients with diffuse large B-cell lymphoma.

Objectives and study design: In this population-based study of 602 patients, we amended C-reactive protein (CRP) and plasma albumin (PA) levels around the diagnosis of diffuse large B-cell lymphoma (DLBCL) to the International Prognostic Index (IPI) and assessed 0-90, 91-365, and +365-day survival.Results: The CRP did not contribute to the IPI's prognostic or discriminatory ability, regardless of time period, particularly not in models with PA. In contrast, the PA was an important contributor, especially in the 0-90 day period, but also up to one year after the diagnosis. For day 0-90, the model with the IPI only had an Area Under the Receiver Operating Characteristics (AUROC) of 0.742, whereas the IPI with PA as a continuous variable rendered an AUROC of 0.841. Especially the lower PA quartile (18-32 g/L) contributed to the worse prognosis.Conclusions: The amendment of PA to the IPI may significantly improve the short-term prognostic and discriminative ability.Key messagesThe amendment of the plasma albumin (PA) level to the International Prognostic Index significantly improved the prediction of mortality up to one year after the diagnosis of diffuse large B-cell lymphoma.It was especially the lower quartile of the PA level (18-32 g/L) that contributed to the worse prognosis.
