BACKGROUND: Ovarian cancer risk in BRCA1 and BRCA2 mutation carriers has been shown to decrease with longer duration of oral contraceptive use. Although the effects of using oral contraceptives in the general population are well established (approximately 50% risk reduction in ovarian cancer), the estimated risk reduction in mutation carriers is much less precise because of potential bias and small sample sizes. In addition, only a few studies on oral contraceptive use have examined the associations of duration of use, time since last use, starting age, and calendar year of start with risk of ovarian cancer. OBJECTIVE: This study aimed to investigate in more detail the associations of various characteristics of oral contraceptive use and risk of ovarian cancer, to provide healthcare providers and carriers with better risk estimates. STUDY DESIGN: In this international retrospective study, ovarian cancer risk associations were assessed using oral contraceptives data on 3989 BRCA1 and 2445 BRCA2 mutation carriers. Age-dependent-weighted Cox regression analyses were stratified by study and birth cohort and included breast cancer diagnosis as a covariate. To minimize survival bias, analyses were left truncated at 5 years before baseline questionnaire. Separate analyses were conducted for each aspect of oral contraceptive use and in a multivariate analysis, including all these aspects. In addition, the analysis of duration of oral contraceptive use was stratified by recency of use. RESULTS: Oral contraceptives were less often used by mutation carriers who were diagnosed with ovarian cancer (ever use: 58.6% for BRCA1 and 53.5% BRCA2) than by unaffected carriers (ever use: 88.9% for BRCA1 and 80.7% for BRCA2). The median duration of use was 7 years for both BRCA1 and BRCA2 carriers who developed ovarian cancer and 9 and 8 years for unaffected BRCA1 and BRCA2 carriers with ovarian cancer, respectively. For BRCA1 mutation carriers, univariate analyses have shown that both a longer duration of oral contraceptive use and more recent oral contraceptive use were associated with a reduction in the risk of ovarian cancer. However, in multivariate analyses, including duration of use, age at first use, and time since last use, duration of oral contraceptive use proved to be the prominent protective factor (compared with <5 years: 5-9 years [hazard ratio, 0.67; 95% confidence interval, 0.40-1.12]; >10 years [hazard ratio, 0.37; 95% confidence interval, 0.19-0.73]; Ptrend=.008). The inverse association between duration of use and ovarian cancer risk persisted for more than 15 years (duration of ≥10 years; BRCA1 <15 years since last use [hazard ratio, 0.24; 95% confidence interval, 0.14-0.43]; BRCA1 >15 years since last use [hazard ratio, 0.56; 95% confidence interval, 0.18-0.59]). Univariate results for BRCA2 mutation carriers were similar but were inconclusive because of limited sample size. CONCLUSION: For BRCA1 mutation carriers, longer duration of oral contraceptive use is associated with a greater reduction in ovarian cancer risk, and the protection is long term.

OBJECTIVE: Intensive Care Units (ICU) acquired Pneumonia (ICU-AP) is one of the most frequent nosocomial infections in critically ill patients. Our aim was to determine the effects of having an ICU-AP in immunosuppressed patients with acute hypoxemic respiratory failure. DESIGN: Post-hoc analysis of a multinational, prospective cohort study in 16 countries. SETTINGS: ICU. PATIENTS: Immunosuppressed patients with acute hypoxemic respiratory failure. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The original cohort had 1611 and in this post-hoc analysis a total of 1512 patients with available data on hospital mortality and occurrence of ICU-AP were included. ICU-AP occurred in 158 patients (10.4%). Hospital mortality was higher in patients with ICU-AP (14.8% vs. 7.1% p < 0.001). After adjustment for confounders and centre effect, use of vasopressors (Odds Ratio (OR) 2.22; 95%CI 1.46-3.39) and invasive mechanical ventilation at day 1 (OR 2.12 vs. high flow oxygen; 95%CI 1.07-4.20) were associated with increased risk of ICU-AP while female gender (OR 0.63; 95%CI 0.43-94) and chronic kidney disease (OR 0.43; 95%CI 0.22-0.88) were associated with decreased risk of ICU-AP. After adjustment for confounders and centre effect, ICU-AP was independently associated with mortality (Hazard Ratio 1.48; 95%CI 14.-1.91; P = 0.003). CONCLUSIONS: The attributable mortality of ICU-AP has been repetitively questioned in immunosuppressed patients with acute respiratory failure. This manuscript found that ICU-AP represents an independent risk factor for hospital mortality.

BACKGROUND AND IMPORTANCE: In 2018, the European Society of Cardiology (ESC) produced syncope guidelines that for the first-time incorporated Emergency Department (ED) management. However, very little is known about the characteristics and management of this patient group across Europe. OBJECTIVES: To examine the prevalence, clinical presentation, assessment, investigation (ECG and laboratory testing), management and ESC and Canadian Syncope Risk Score (CSRS) categories of adult European ED patients presenting with transient loss of consciousness (TLOC, undifferentiated or suspected syncope). DESIGN: Prospective, multicentre, observational cohort study. SETTINGS AND PARTICIPANTS: Adults (≥18 years) presenting to European EDs with TLOC, either undifferentiated or thought to be of syncopal origin. MAIN RESULTS: Between 00:01 Monday, September 12th to 23:59 Sunday 25 September 2022, 952 patients presenting to 41 EDs in 14 European countries were enrolled from 98 301 ED presentations (n = 40 sites). Mean age (SD) was 60.7 (21.7) years and 487 participants were male (51.2%). In total, 379 (39.8%) were admitted to hospital and 573 (60.2%) were discharged. 271 (28.5%) were admitted to an observation unit first with 143 (52.8%) of these being admitted from this. 717 (75.3%) participants were high-risk according to ESC guidelines (and not suitable for discharge from ED) and 235 (24.7%) were low risk. Admission rate increased with increasing ESC high-risk factors; 1 ESC high-risk factor; n = 259 (27.2%, admission rate=34.7%), 2; 189 (19.9%; 38.6%), 3; 106 (11.1%, 54.7%, 4; 62 (6.5%, 60.4%), 5; 48 (5.0%, 67.9%, 6+; 53 (5.6%, 67.9%). Furthermore, 660 (69.3%), 250 (26.3%), 34 (3.5%) and 8 (0.8%) participants had a low, medium, high, and very high CSRS respectively with respective admission rates of 31.4%, 56.0%, 76.5% and 75.0%. Admission rates (19.3-88.9%), use of an observation/decision unit (0-100%), and percentage high-risk (64.8-88.9%) varies widely between countries. CONCLUSION: This European prospective cohort study reported a 1% prevalence of syncope in the ED. 4 in 10 patients are admitted to hospital although there is wide variation between country in syncope management. Three-quarters of patients have ESC high-risk characteristics with admission percentage rising with increasing ESC high-risk factors.

BACKGROUND: High-efficacy therapies in multiple sclerosis are traditionally used after unsuccessful treatment with first-line disease modifying therapies. We hypothesised that early commencement of high-efficacy therapy would be associated with reduced long-term disability. We therefore aimed to compare long-term disability outcomes between patients who started high-efficacy therapies within 2 years of disease onset with those who started 4-6 years after disease onset. METHODS: In this retrospective international observational study, we obtained data from the MSBase registry and the Swedish MS registry, which prospectively collect patient data that are specific to multiple sclerosis as part of routine clinical care. We identified adult patients (aged ≥18 years) with relapsing-remitting multiple sclerosis, with at least 6 years of follow-up since disease onset, and who started the high-efficacy therapy (rituximab, ocrelizumab, mitoxantrone, alemtuzumab, or natalizumab) either 0-2 years (early) or 4-6 years (late) after clinical disease onset. We matched patients in the early and late groups using propensity scores calculated on the basis of their baseline clinical and demographic data. The primary outcome was disability, measured with the Expanded Disability Status Score (EDSS; an ordinal scale of 0-10, with higher scores indicating increased disability), at 6-10 years after disease onset, assessed with a linear mixed-effects model. FINDINGS: We identified 6149 patients in the MSBase registry who had been given high-efficacy therapy, with data collected between Jan 1, 1975, and April 13, 2017, and 2626 patients in the Swedish MS Registry, with data collected between Dec 10, 1997, and Sept 16, 2019. Of whom, 308 in the MSBase registry and 236 in the Swedish MS registry were eligible for inclusion. 277 (51%) of 544 patients commenced therapy early and 267 (49%) commenced therapy late. For the primary analysis, we matched 213 patients in the early treatment group with 253 in the late treatment group. At baseline, the mean EDSS score was 2·2 (SD 1·2) in the early group and 2·1 (SD 1·2) in the late group. Median follow-up time for matched patients was 7·8 years (IQR 6·7-8·9). In the sixth year after disease onset, the mean EDSS score was 2·2 (SD 1·6) in the early group compared with 2·9 (SD 1·8) in the late group (p<0·0001). This difference persisted throughout each year of follow-up until the tenth year after disease onset (mean EDSS score 2·3 [SD 1·8] vs 3·5 [SD 2·1]; p<0·0001), with a difference between groups of -0·98 (95% CI -1·51 to -0·45; p<0·0001, adjusted for proportion of time on any disease-modifying therapy) across the 6-10 year follow-up period. INTERPRETATION: High-efficacy therapy commenced within 2 years of disease onset is associated with less disability after 6-10 years than when commenced later in the disease course. This finding can inform decisions regarding optimal sequence and timing of multiple sclerosis therapy. FUNDING: National Health and Medical Research Council Australia and MS Society UK.

Úvod: Prevalencia a fenotyp astmy sa v rámci rôznych populácií líšia. Za najvýznamnejší rizikový faktor pre vývoj bronchiálnej astmy sa všeobecne považuje atopia, ktorú definujeme ako prítomnosť IgE proti potravinovým a inhalačným alergénom. Informácie o astme a alergickej senzibilizácii u detí predškolského veku z regiónu strednej Európy sú len sporadické. Metódy: Longitudinálna kohortová štúdia v rokoch 2002–2008 u 230 detí z dvoch environmentálne odlišných regiónov Slovenska, sledovaných od narodenia do 5. roku života. Počas vyšetrení v 18. mesiaci, 3 rokoch a 5 rokoch sa zisťovala prítomnosť symptómov opakovaného pískania na hrudníku, lekárom diagnostikovanej astmy a prítomnosť IgE protilátok proti najčastejším potravinovým a inhalačným alergénom. Súčasne sa sledovala prítomnosť najvýznamnejších rizikových faktorov pre astmu a alergiu pomocou dotazníkov. Výsledky: Anamnéza opakovaných príznakov pískania na hrudníku bola pozitívna najčastejšie v 3. roku, u 13,8 % detí. Percento detí s diagnózou astmy stúpalo do 5. roka, kedy bola frekvencia 7,2 %.Medzi dvomi sledovanými regiónmi sa nezistil štatisticky významný rozdiel v príznakoch pískania ani v diagnóze astmy. Senzibilizácia na potravinové alergény dosiahla vrchol u detí v 3. roku života (15,7 %), senzibilizácia na inhalačné alergény bola najvyššia v 5. roku. V Bratislave sa v 5. roku zistila senzibilizácia na inhalačné alergény u 16,9 % detí, v Starej Ľubovni u 6,7 % detí (p = 0,046). Jediným nezávislýmrizikovýmfaktorompre diagnózu astmy bol počet respiračných infekcií v 5. roku (p = 0,027; aOR 1,49; 95% KI 1,0–2,1). Nezávislým rizikovým faktorom pre alergickú senzibilizáciu na inhalačné alergény bola senzibilizácia na potravinové alergény (p = 0,003; aOR = 9,5; 95% KI 2,1–42,4). K štatistickej významnosti sa blížil ochranný účinok dojčenia a kontakt s hospodárskymi zvieratami. Prítomnosť senzibilizácie na inhalačné alergény u 5-ročných detí s astmou sa zistil v 27,3 % prípadov. Záver: Astma u detí predškolského veku bola v našej štúdii z väčšej miery spojená s infekciami dýchacích ciest. Nezistili sme rozdiely v prevalencii v dvoch environmentálne odlišných regiónoch Slovenska. Senzibilizácia na inhalačné alergény bola u 5-ročných detí dvojnásobne vyššia v Bratislave ako v Starej Ľubovni.

Background: Prevalence and phenotype of asthma vary among different populations. In general, the atopy is considered to be themost significant risk factor for asthma. Atopy is defined as a presence of IgE against food and inhalant allergens. Information about asthma and allergic sensitization in preschool children from Central European region is sporadic. Methods: Longitudinal cohort study in years 2002–2008 of 230 children from two environmentally different regions of Slovakia followed from birth to 5th year of life. During the follow-up visits at 18th month, 3rd year and 5th year the symptoms of repeated chest wheezing, physician diagnosed asthma and levels of IgE against most frequent food and inhalant allergens were examined. Concurrently we examined the most important risk factors for asthma and allergy. Results: History of repeated symptoms of chest wheezing was most frequent at 3rd year, in 13.8% of children. Percentage of children with physician diagnosed asthma increased until 5th year, when the frequency was 7.2%. No statistically significant differences in wheezing and/or asthma were found between the two regions. Sensitization to food allergens peaked at year 3 (15.7%), sensitization to inhalant allergens was highest at year 5. Sensitization to inhalant allergens reached 16.9 % in Bratislava (industrial region), compared to 6.9 % in Stará Lubovňa (rural region; p=0.046). The only independent risk factor for asthma diagnosis at 5th year was the rate of respiratory infections at 5th year (p=0.027; aOR 1.49; 95% CI 1.0–2.1). The independent risk factor for sensitization against inhalant allergens was sensitization to food allergens (p=0.003; aOR=9.5; 95% CI 2.1–42.4). Protective effect of farming and breast feeding was close to significance. Sensitization against inhalant allergens in 5 year old children with diagnosed asthma has reached 27.3%. Conclusion: In children of pre-school age, asthma was mostly connected to respiratory infections. There were no differences between rural and industrial regions of Slovakia. Sensitization rate against inhalant allergens in 5 year old children from industrial region doubled the rate in rural region.

BACKGROUND: Hypertriglyceridemia is the third most common cause of acute pancreatitis (AP). It has been shown that hypertriglyceridemia aggravates the severity and related complications of AP; however, detailed analyses of large cohorts are contradictory. Our aim was to investigate the dose-dependent effect of hypertriglyceridemia on AP. METHODS: AP patients over 18 years old who underwent triglyceride measurement within the initial three days were included into our cohort analysis from a prospective international, multicenter AP registry operated by the Hungarian Pancreatic Study Group. Data on 716 AP cases were analyzed. Six groups were created based on the highest triglyceride level (<1.7 mmol/l, 1.7-2.19 mmol/l, 2.2-5.59 mmol/l, 5.6-11.29 mmol/l, 11.3-22.59 mmol/l, ≥22.6 mmol/l). RESULTS: Hypertriglyceridemia (≥1.7 mmol/l) presented in 30.6% of the patients and was significantly and dose-dependently associated with younger age and male gender. In 7.7% of AP cases, hypertriglyceridemia was considered as a causative etiological factor (≥11.3 mmol/l); however, 43.6% of these cases were associated with other etiologies (alcohol and biliary). Hypertriglyceridemia was significantly and dose-dependently related to obesity and diabetes. The rates of local complications and organ failure and maximum CRP level were significantly and dose-dependently raised by hypertriglyceridemia. Triglyceride above 11.3 mmol/l was linked to a significantly higher incidence of moderately severe AP and longer hospital stay, whereas triglyceride over 22.6 mmol/l was significantly associated with severe AP as well. CONCLUSION: Hypertriglyceridemia dose-dependently aggravates the severity and related complications of AP. Diagnostic workup for hypertriglyceridemia requires better awareness regardless of the etiology of AP.

BACKGROUND: Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse. METHODS: We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group. RESULTS: Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m2 (range; 15-49). The risk of recurrence for patients who underwent minimally invasive surgery was twice as high as that in the open surgery group (HR, 2.07; 95% CI, 1.35 to 3.15; P=0.001). Similarly, the risk of death was 2.42-times higher than in the open surgery group (HR, 2.45; 95% CI, 1.30 to 4.60, P=0.005). Patients that underwent minimally invasive surgery using a uterine manipulator had a 2.76-times higher hazard of relapse (HR, 2.76; 95% CI, 1.75 to 4.33; P<0.001) and those without the use of a uterine manipulator had similar disease-free-survival to the open surgery group (HR, 1.58; 95% CI, 0.79 to 3.15; P=0.20). Moreover, patients that underwent minimally invasive surgery with protective vaginal closure had similar rates of relapse to those who underwent open surgery (HR, 0.63; 95% CI, 0.15 to 2.59; P<0.52). CONCLUSIONS: Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted.

PURPOSE: Due to the lack of effective screening approaches and early detection biomarkers, ovarian cancer has the highest mortality rates among gynecologic cancers. Herein, we undertook a systematic biomarker discovery and validation approach to identify microRNA (miRNA) biomarkers for the early detection of ovarian cancer. EXPERIMENTAL DESIGN: During the discovery phase, we performed small RNA sequencing in stage I high-grade serous ovarian cancer (n = 31), which was subsequently validated in multiple, independent data sets (TCGA, n = 543; GSE65819, n = 87). Subsequently, we performed multivariate logistic regression-based training in a serum data set (GSE106817, n = 640), followed by its independent validation in three retrospective data sets (GSE31568, n = 85; GSE113486, n = 140; Czech Republic cohort, n = 192) and one prospective serum cohort (n = 95). In addition, we evaluated the specificity of OCaMIR, by comparing its performance in several other cancers (GSE31568 cohort, n = 369). RESULTS: The OCaMIR demonstrated a robust diagnostic accuracy in the stage I high-grade serous ovarian cancer patients in the discovery cohort (AUC = 0.99), which was consistently reproducible in both stage I (AUC = 0.96) and all stage patients (AUC = 0.89) in the TCGA cohort. Logistic regression-based training and validation of OCaMIR achieved AUC values of 0.89 (GSE106817), 0.85 (GSE31568), 0.86 (GSE113486), and 0.82 (Czech Republic cohort) in the retrospective serum validation cohorts, as well as prospective validation cohort (AUC = 0.92). More importantly, OCaMIR demonstrated a significantly superior diagnostic performance compared with CA125 levels, even in stage I patients, and was more cost-effective, highlighting its potential role for screening and early detection of ovarian cancer. CONCLUSIONS: Small RNA sequencing identified a robust noninvasive miRNA signature for early-stage serous ovarian cancer detection.

INTRODUCTION: Cardiogenic shock is a frequent complication of acute myocardial infarction. Similar to ischemia/reperfusion injury, excessive production of reactive oxygen species can be expected in those who experience cardiogenic shock. The aims of this study were to describe the extent and time course of oxidative stress and evaluate the prognostic value of oxidative stress markers in patients who experienced ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock. METHODS: Plasma/serum levels of selected biomarkers of oxidative stress (oxidised guanine species (OGS), malondialdehyde, and glutathione peroxidase 3) and markers, which simultaneously reflect severe cellular damage (ferric ion reducing antioxidant power (FRAP), Cu/Zn-superoxide dismutase (SOD), and glutathione) were measured seven times per week in a prospective cohort of 82 patients with STEMI complicated by cardiogenic shock. RESULTS: We found elevated OGS levels in patients who died during three months, which persisted significantly increased the next 12 h compared to surviving patients. A similar time course pattern also exhibited concentrations of FRAP and SOD. The other markers did not change significantly and did not show differences between surviving and non-surviving patients during the monitored period. In addition, a strong relationship between OGS, FRAP, and SOD levels (on admission and 12 h after admission) and 3-month mortality was found. CONCLUSION: Levels of OGS, FRAP, and SOD within 12 h after hospital admission were revealed as early predictors of the adverse development of STEMI complicated by cardiogenic shock.

BACKGROUND: Medical nutrition therapy may be associated with clinical outcomes in critically ill patients with prolonged intensive care unit (ICU) stay. We wanted to assess nutrition practices in European intensive care units (ICU) and their importance for clinical outcomes. METHODS: Prospective multinational cohort study in patients staying in ICU ≥ 5 days with outcome recorded until day 90. Macronutrient intake from enteral and parenteral nutrition and non-nutritional sources during the first 15 days after ICU admission was compared with targets recommended by ESPEN guidelines. We modeled associations between three categories of daily calorie and protein intake (low: < 10 kcal/kg, < 0.8 g/kg; moderate: 10-20 kcal/kg, 0.8-1.2 g/kg, high: > 20 kcal/kg; > 1.2 g/kg) and the time-varying hazard rates of 90-day mortality or successful weaning from invasive mechanical ventilation (IMV). RESULTS: A total of 1172 patients with median [Q1;Q3] APACHE II score of 18.5 [13.0;26.0] were included, and 24% died within 90 days. Median length of ICU stay was 10.0 [7.0;16.0] days, and 74% of patients could be weaned from invasive mechanical ventilation. Patients reached on average 83% [59;107] and 65% [41;91] of ESPEN calorie and protein recommended targets, respectively. Whereas specific reasons for ICU admission (especially respiratory diseases requiring IMV) were associated with higher intakes (estimate 2.43 [95% CI: 1.60;3.25] for calorie intake, 0.14 [0.09;0.20] for protein intake), a lack of nutrition on the preceding day was associated with lower calorie and protein intakes (- 2.74 [- 3.28; - 2.21] and - 0.12 [- 0.15; - 0.09], respectively). Compared to a lower intake, a daily moderate intake was associated with higher probability of successful weaning (for calories: maximum HR 4.59 [95% CI: 1.5;14.09] on day 12; for protein: maximum HR 2.60 [1.09;6.23] on day 12), and with a lower hazard of death (for calories only: minimum HR 0.15, [0.05;0.39] on day 19). There was no evidence that a high calorie or protein intake was associated with further outcome improvements. CONCLUSIONS: Calorie intake was mainly provided according to the targets recommended by the active ESPEN guideline, but protein intake was lower. In patients staying in ICU ≥ 5 days, early moderate daily calorie and protein intakes were associated with improved clinical outcomes.
