Tachyphylaxis and reproducibility of desmopressin response in perioperative persons with nonsevere hemophilia A: implications for clinical practice. Res Pract Thromb Haemost 2024; 8:102367. [PMID: 38660455 PMCID: PMC11039391 DOI: 10.1016/j.rpth.2024.102367] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 01/25/2024] [Accepted: 02/11/2024] [Indexed: 04/26/2024] Open
Abstract
Background Desmopressin is frequently used perioperatively in persons with nonsevere hemophilia A. However, increase in factor (F)VIII:C after desmopressin use is interindividually highly variable. Tachyphylaxis has only been reported in test setting for persons with hemophilia A, with a remaining response of approximately 70% after a second dose compared with that after a first dose. Objectives To study tachyphylaxis of FVIII:C response after multiple administration(s) of desmopressin in perioperative persons with nonsevere hemophilia A. Methods We studied FVIII:C levels after desmopressin before (day 0 [D0]) and on days 1 (D1) and 2 (D2) after surgery in 26 patients of the DAVID and Little DAVID studies. We studied tachyphylaxis by comparing the responses at D1 and D2 with that at D0. We also assessed the reproducibility of the D0 response in comparison to an earlier performed desmopressin test. Results The median absolute FVIII:C increase was 0.50 IU/mL (0.35-0.74; n = 23) at D0, 0.21 IU/mL (0.14-0.28; n = 17) at D1, and 0.23 IU/mL (0.16-0.30; n = 11) at D2. The median percentage of FVIII increase after the second administration (D1) compared with the first (D0) was 42.9% (29.2%-52.5%; n = 17) and that of the third (D2) compared with the first (D0) was 36.4% (23.7%-46.9%; n = 11). The FVIII:C desmopressin response at D0 was comparable with the desmopressin test response in 74% of the patients. Conclusion Tachyphylaxis in the surgical setting was considerably more pronounced than previously reported, with FVIII:C at D1 and D2 of 36% to 43% of the initial response. Our results may have important implications for monitoring repeated desmopressin treatment when used perioperatively.

Adjuvants for balanced anesthesia in ambulatory surgery. Best Pract Res Clin Anaesthesiol 2023; 37:409-420. [PMID: 37938086 DOI: 10.1016/j.bpa.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 12/15/2022] [Accepted: 12/28/2022] [Indexed: 01/06/2023]
Abstract
Balanced anesthesia relies on the simultaneous administration of different drugs to attain an anesthetic state. The classic triad of anesthesia is a combination of a hypnotic, an analgesic, and a neuromuscular blocker. It is predominantly the analgesic pillar of this triad that became more and more supported by adjuvant therapy. The aim of this approach is to evolve into an opioid-sparing technique to cope with undesirable side effects of the opioids and is fueled by the opioid epidemic. The optimal strategy for balanced general anesthesia in ambulatory surgery must aim for a transition to a multimodal analgesic regimen dealing with acute postoperative pain and ideally reduce the most common adverse effects patients are faced with at home; sore throat, delayed awakening, memory disturbances, headache, nausea and vomiting, and negative behavioral changes. Over the years, this continuum of "multimodal general anesthesia" adopted many drugs with different modes of action. This review focuses on the most recent evidence on the different adjuvants that entered clinical practice and gives an overview of the different mechanisms of action, the potential as opioid-sparing or hypnotic-sparing drugs, and the applicability specifically in ambulatory surgery.

Abstract
BACKGROUND Andexanet alfa is a modified recombinant inactive factor Xa (FXa) designed to reverse FXa inhibitors. ANNEXA-4 (Andexanet Alfa, a Novel Antidote to the Anticoagulation Effects of Factor Xa Inhibitors) was a multicenter, prospective, phase-3b/4, single-group cohort study that evaluated andexanet alfa in patients with acute major bleeding. The results of the final analyses are presented. METHODS Patients with acute major bleeding within 18 hours of FXa inhibitor administration were enrolled. Co-primary end points were anti-FXa activity change from baseline during andexanet alfa treatment and excellent or good hemostatic efficacy, defined by a scale used in previous reversal studies, at 12 hours. The efficacy population included patients with baseline anti-FXa activity levels above predefined thresholds (≥75 ng/mL for apixaban and rivaroxaban, ≥40 ng/mL for edoxaban, and ≥0.25 IU/mL for enoxaparin; reported in the same units used for calibrators) who were adjudicated as meeting major bleeding criteria (modified International Society of Thrombosis and Haemostasis definition). The safety population included all patients. Major bleeding criteria, hemostatic efficacy, thrombotic events (stratified by occurring before or after restart of either prophylactic [ie, a lower dose, for prevention rather than treatment] or full-dose oral anticoagulation), and deaths were assessed by an independent adjudication committee. Median endogenous thrombin potential at baseline and across the follow-up period was a secondary outcome. RESULTS There were 479 patients enrolled (mean age, 78 years; 54% male, 86% White; 81% anticoagulated for atrial fibrillation at a median time of 11.4 hours since last dose, with 245 (51%) on apixaban, 176 (37%) on rivaroxaban, 36 (8%) on edoxaban, and 22 (5%) on enoxaparin. Bleeding was predominantly intracranial (n=331 [69%]) or gastrointestinal (n=109 [23%]). In evaluable apixaban patients (n=172), median anti-FXa activity decreased from 146.9 ng/mL to 10.0 ng/mL (reduction, 93% [95% CI, 94-93]); in rivaroxaban patients (n=132), it decreased from 214.6 ng/mL to 10.8 ng/mL (94% [95% CI, 95-93]); in edoxaban patients (n=28), it decreased from 121.1 ng/mL to 24.4 ng/mL (71% [95% CI, 82-65); and in enoxaparin patients (n=17), it decreased from 0.48 IU/mL to 0.11 IU/mL (75% [95% CI, 79-67]). Excellent or good hemostasis occurred in 274 of 342 evaluable patients (80% [95% CI, 75-84]). In the safety population, thrombotic events occurred in 50 patients (10%); in 16 patients, this occurred during treatment with prophylactic anticoagulation that began after the bleeding event. No thrombotic episodes occurred after oral anticoagulation restart. Specific to certain populations, reduction of anti-FXa activity from baseline to nadir significantly predicted hemostatic efficacy in patients with intracranial hemorrhage (area under the receiver operating characteristic curve, 0.62 [95% CI, 0.54-0.70]) and correlated with lower mortality in patients <75 years of age (adjusted P=0.022; unadjusted P=0.003). Median endogenous thrombin potential was within the normal range by the end of andexanet alfa bolus through 24 hours for all FXa inhibitors. CONCLUSIONS In patients with major bleeding associated with the use of FXa inhibitors, treatment with andexanet alfa reduced anti-FXa activity and was associated with good or excellent hemostatic efficacy in 80% of patients.

Abstract
INTRODUCTION Recent guidelines advocate a preoperative fasting interval of 6 h for solid food, 4 h for breast milk and 2 h for clear fluids. Long nil per mouth intervals give rise to complications and discomfort in the perioperative period. Gastric ultrasound is easily accessible and generates reliable information about gastric content. PATIENTS AND METHODS One hundred patients were offered a questionnaire regarding preoperative fasting. Important outcome measures were hour of last meal, last clear fluids intake, the source of preoperative information. Gastric ultrasound was performed in prone position and lateral decubitus. RESULTS The mean duration of fasting for solid food was 13h29 and 9h51 for clear fluids. 48% of patients were well aware of the correct fasting guidelines. The most frequent source of information was the preoperative phone call. Gastric ultrasound only found insignificant amounts of gastric content. DISCUSSION Too few patients are aware of the correct guidelines or fear complications and therefore adhere to the nil per mouth from midnight as most conservative measure. A phone call informing patients about the hour of surgery and allowing clear fluid intake until 2 h before surgery, is still not convincing enough. Some health care providers advise their patients the nil per mouth from midnight rule, due to risk of interfering with the operating room schedule. CONCLUSION It is still difficult to implement liberal intake of clear fluids according to current guidelines. Ambulatory surgery patients have long fasting intervals with decrease of subjective well-being and increased incidence of hunger and thirst.

Abstract
INTRODUCTION The incidence of adverse events in day surgery is an important quality indicator. This retrospective study investigated factors independently associated with unanticipated admission of pediatric patients after ambulatory surgery. PATIENTS AND METHODS Ambulatory pediatric patients requiring unanticipated admission between January 2016 and December 2018 were compared to ambulatory pediatric patients who were discharged home after a planned surgery. Demographic data, organizational data, American Society of Anesthesiologists (ASA) classification, type of surgery, type of anesthesia, length of surgery, time of completion of the surgery, campus site, and season were collected in both groups. The reason for unexpected admission was classified according to four subtypes: anesthetic, medical, social/organizational and surgical reason, respectively. Multivariate logistic regression was used to identify independent factors associated with unanticipated admission. RESULTS From a total of 4235 pediatric patients, 78 children (1.9%) required unanticipated admission. The reasons for admission were anesthetic n = 29 (37.3%), surgical n = 20 (25.6%), medical n = 16 (20.5%) and social/organizational n = 13 (16.6%). Age <2 years (odds ratio [OR] 3.005, 95% confidence interval (CI) 1.500-6.018; ASA class 2 (OR 2.144; 95% CI 1.193-3.852); ASA class 3 (OR 11.617; CI 5.698-23.685); length of surgery >2 h (OR 3.056; CI 1.829-5.107); completion of surgery > 2:30 PM (OR 3.507; CI 1.854-6.633) and campus site (OR 3.628; CI 1.991-6.610) were factors significantly associated with unanticipated admission. CONCLUSION Children are less likely to be admitted after ambulatory surgery when preoperatively carefully selected and when prioritized considering age, general health condition and invasiveness of the surgery.

Platelet degranulation and bleeding phenotype in a large cohort of Von Willebrand disease patients. Br J Haematol 2022; 197:497-501.

Abstract
Von Willebrand disease (VWD) is a bleeding disorder caused by quantitative (type 1 or 3) or qualitative (type 2A/2B/2M/2N) defects of circulating von Willebrand factor (VWF). Circulating VWF levels not always fully explain bleeding phenotypes, suggesting a role for alternative factors, like platelets. Here, we investigated platelet factor 4 (PF4) in a large cohort of patients with VWD. PF4 levels were lower in type 2B and current bleeding phenotype was significantly associated with higher PF4 levels, particularly in type 1 VWD. Based on our findings we speculate that platelet degranulation and cargo release may play a role across VWD subtypes.

Five vs. two initial rescue breaths during infant basic life support: A manikin study using bag-mask-ventilation. Front Pediatr 2022; 10:1067971.

Abstract
BACKGROUND AND OBJECTIVES Children are more likely to suffer a hypoxic-ischaemic cause for cardiac arrest. Early ventilation may provide an advantage in outcome during paediatric cardiopulmonary resuscitation [CPR]. European Resuscitation Council guidelines recommend five initial rescue breaths [IRB] in infants, stemming from the hypothesis that rescuers might need 5 attempts in order to deliver 2 effective ventilations. This study aimed to verify this hypothesis. METHODS Participants (n = 112, convenience sample) were medical students from the Faculty of Medicine and Health Sciences Ghent University, Belgium. Students were divided into duos and received a 15 min just-in-time training regarding the full CPR-cycle using BMV. Participants then performed five cycles of 2-person CPR. The IRB were given by 1-person BMV, as opposed to a 2-persons technique during the further CPR-cycle. Correct ventilations for the infant were defined as tidal volumes measured (Laerdal® Q-CPR) between 20 and 60 ml, with n = 94 participants included in the analysis. The primary outcome consisted of the difference in the % of medical student duos providing at least 2 effective IRB between 2 and 5 attempts. RESULTS Off all duos, 55,3% provided correct volumes during their first 2 initial ventilations. An increase up to 72,4% was noticed when allowing 5 ventilations. The proportional difference between 2 and 5 IRB allowed was thus significant [17,0%, 95% confidence interval (5.4; 28.0)]. CONCLUSION In this manikin study, 5 IRB attempts during infant CPR with BMV increased the success rate in delivering 2 effective ventilations. Besides, students received training emphasizing the need for 5 initial rescue breaths. This study provides evidence supporting European Resuscitation Council guidelines.

Abstract
PURPOSE OF REVIEW To give an overview of the impact of different forms of telehealth that are currently used in ambulatory anesthesia and surgery. Telehealth is applicable during the early recovery and intermediate recovery period (e.g. monitoring of quality of recovery), and as a tool for postoperative check-up during the late recovery phase. RECENT FINDINGS Postoperative follow-up after ambulatory surgery is still crucial to maintain quality of care as pain and postoperative nausea and vomiting remain common adverse events. There is a surge of telehealth applications from procedure-specific commercial smartphone apps (mHealth) to complete digital patient platforms instituted by the government. However, patient and healthcare provider engagement is not universal. Usability of these applications is mandatory as well as identifying and overcoming the barriers to its use. SUMMARY Telehealth gives many opportunities for postoperative follow-up of ambulatory surgery patients. Clear evidence on the benefits of telehealth in ambulatory surgery is however still sparse. Future research should focus on telehealth for improving quality and safety of postoperative recovery, convincing policymakers for reimbursement encouraging healthcare providers and patients to engage in telehealth.

Syncope in Dental Practices: A Systematic Review on Aetiology and Management. J Evid Based Dent Pract 2021; 21:101581.

Abstract
INTRODUCTION This systematic review aimed to give an overview of the current evidence surrounding the aetiology and management in terms of treatment and prevention of syncope in dental practices. Alongside the occurrence, the practitioner's competence, and the association between syncope and local anaesthetics were discussed. METHODS An electronic search in EMBASE, Web of Science, PubMed, Cochrane databases and a hand search were performed by 2 independent reviewers to identify studies up to November 2019. Eligibility criteria were applied and relevant data was extracted. Inclusion criteria covered all types of dental treatment under local anaesthesia or conscious sedation performed by a wide range of oral health care workers in their practices. Risk of bias of the included studies was assessed using the methodological tools recommend by Zeng et al.1 No restrictions were made to exclude papers from qualitive analysis based on risk of bias assessment. RESULTS The search yielded a total of 18 studies for qualitative analysis. With the exception of one prospective cohort study, all articles were considered having a high risk of bias. Meta-analysis showed that dentists encountered on average 1.2 cases of syncope per year. The male gender (RR = 2.69 [1.03, 7.02]), dental fear (RR = 3.55 [2.22, 5.70]), refusal of local anaesthesia in non-acute situations (OR = 12.9) and the use of premedication (RR = 4.70, [1.30, 16.90]) increased the risk for syncope. Treatment and prevention were underreported as both were solely discussed in one study. The supine recovery position with raised legs and oxygen administration (15l/min) was presented as an effective treatment. The Medical Risk-Related History (MRRH) system was proposed as prevention protocol, yet this protocol was ineffective in reducing incidence rates (p = 0.27). The majority of dentists (79.2%) were able to diagnose syncope, yet most (86%) lacked the skills for appropriate treatment. Only 57,6% of dental practices were equipped with an oxygen cylinder. CONCLUSIONS Syncope is the most common emergency in dental practices. Nonetheless, the vast majority of dentists do not seem competent nor prepared to manage this emergency. Psychogenic factors seem to play an important role in provoking syncope. Placing the patient in a supine reclined position with raised legs in combination with the administration of oxygen seems effective for regaining consciousness. Although valuable in many aspects, risk assessment by medical history taking is not proven to result in fewer episodes. The strength of these conclusions is low based on GRADE guidelines.2.

Laryngeal mask airway protector generates higher oropharyngeal leak pressures compared to the laryngeal mask airway supreme: A randomized clinical trial in the ambulatory surgery unit. J Anaesthesiol Clin Pharmacol 2021; 37:221-225. [PMID: 34349370 PMCID: PMC8289652 DOI: 10.4103/joacp.joacp_416_19] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 01/26/2020] [Accepted: 03/13/2020] [Indexed: 11/04/2022] Open
Abstract
Background and Aims The Laryngeal Mask Airway (LMA) Protector™ is one of the latest introduced supraglottic airway devices. It provides access and functional separation of the respiratory and digestive tracts. Compared to the LMA Supreme™, it has two digestive ports, one to provide suction in the pharyngeal region and one for gastric tube insertion. High oropharyngeal leak pressure is a marker for safe ventilation when using LMA devices. We hypothesized that oropharyngeal leak pressure of the LMA Protector™ is 5 cm H2O higher than the oropharyngeal leak pressure of the LMA Supreme™ at various cuff volumes. Secondary outcome measures were ease of insertion of both masks, fiberoptic confirmation of correct positioning, failures of insertion, presence of blood staining, sore throat, presence of air leak and insertion time. Material and Methods American Society of Anesthesiologists (ASA) I-III patients aged >18 years, scheduled for elective minor ambulatory surgery under general anesthesia with a LMA were included. Patients were randomized in the LMA Protector™ or LMA Supreme™ group based on a computer-generated random sequence table. After general anesthesia induction, oropharyngeal leak pressures were measured. Results Oropharyngeal leak pressures were significantly higher (P < 0.0001) for LMA Protector™ compared to LMA Supreme™ at different cuff volumes and a cuff pressure of 65 cm H2O. Insertion time was significantly higher for the LMA Protector™ (29 sec) [interquartile range (IQR) 23, 35] compared to the LMA Supreme™ (19 sec) (IQR 16, 22) (P < 0.0001). There were no statistically significant differences in ease of insertion (number of attempts for succesful positioning), failures of insertion, presence of blood staining, sore throat or presence of air leak. Conclusion Oropharyngeal leak pressures were consistently higher (>5 cm H2O) for LMA Protector™ compared to LMA Supreme™. LMA Protector™, therefore, allows effective ventilation at higher airway pressures than LMA Supreme™. Trial Registration http://clinicaltrials.gov.NCT03462550.

Abstract
A new protocol was developped to prolong deep inspiration breath-holds. Multiple prolonged breath-holds are achievable with minimal side effects. DIBH was prolonged to 3 min using HFNO and hyperventilation in breast cancer patients.
Background and purpose Deep inspiration breath-hold is an established technique to reduce heart dose during breast cancer radiotherapy. However, modern breast cancer radiotherapy techniques with lymph node irradiation often require long beam-on times of up to 5 min. Therefore, the combination with deep inspiration breath-hold (DIBH) becomes challenging. A simple support technique for longer duration deep inspiration breath-hold (L-DIBH), feasible for daily use at the radiotherapy department, is required to maximize heart sparing. Materials and methods At our department, a new protocol for multiple L-DIBH of at least 2 min and 30 s was developed on 32 healthy volunteers and validated on 8 breast cancer patients during radiotherapy treatment, using a pragmatic process of iterative development, including all major stakeholders. Each participant performed 12 L-DIBHs, on 4 different days. Different methods of pre-oxygenation and voluntary hyperventilation were tested, and scored on L-DIBH duration, ease of use, and comfort. Results Based on 384 L-DIBHs from 32 healthy volunteers, voluntary hyperventilation for 3 min whilst receiving high-flow nasal oxygen at 40 L/min was the most promising technique. During validation, the median L-DIBH duration in prone position of 8 breast cancer patients improved from 59 s without support to 3 min and 9 s using the technique (p < 0.001). Conclusion A new and simple L-DIBH protocol was developed feasible for daily use at the radiotherapy center.

Abstract
BACKGROUND Patients with stable coronary artery disease (CAD) or peripheral artery disease (PAD) are at substantial risk of atherothrombotic events. The COMPASS trial showed that patients with stable CAD or PAD experienced significant benefits after treatment with rivaroxaban in combination with acetylsalicylic acid (ASA) compared with ASA alone. This paper aims to provide insight into the clinical and economic consequences of treatment with rivaroxaban from a Dutch societal perspective. METHODS The clinical and economic implications of rivaroxaban in terms of the number of events prevented, costs, the incremental cost per life-years gained (LYG), and incremental cost per quality-adjusted life-years (QALYs) were determined based on a cost-effectiveness model for patients with stable CAD or PAD and in high-risk subgroups (i.e. patients with CAD and PAD, CAD and prior myocardial infarction and renal impairment, CAD and heart failure) using results from the Cardiovascular OutcoMes for People Using Anticoagulation Strategies (COMPASS) trial. RESULTS Patients treated with rivaroxaban have an expected increased discounted life expectancy of 0.67 years. In high-risk groups discounted incremental life expectancy ranged from 1.33 to 1.90 years. The incremental cost-effectiveness ratio for the full COMPASS population was €9,760/LYG and €12,033/QALY, whereas, for high-risk subgroups of patients with underlying conditions, incremental cost-effectiveness ratios ranged from €2,966/LYG to €5,052/LYG and from €3,940/QALY to €6,815/QALY. Results from the sensitivity analyses revealed that the model results were robust to variations in single or multiple input parameters at once. CONCLUSIONS The cost-effectiveness analysis showed that rivaroxaban in combination with ASA is a cost-effective treatment option in stable CAD or PAD patients. Rivaroxaban in combination with ASA is even more cost-effective in high-risk subgroups.

Abstract
BACKGROUND It is unknown whether international guidelines on gestational weight gain can be used in pregnancies after bariatric surgery. OBJECTIVES To investigate gestational weight gain, intrauterine growth, and postpartum weight retention in postbariatric women. SETTING 8 Belgian hospitals. METHODS Prospective data from 127 postbariatric pregnancies from September 2014 through October 2018. Patients were grouped according to achievement of 2009 Institute of Medicine (IOM) guidelines. RESULTS In 127 patients with a mean age of 30.2 years (standard deviation [SD], 4.7), the mean gestational weight gain was 12.5 kg (SD, 6.7). Of these patients, 24% (30 of 127) showed insufficient weight gain, 20% (26 of 127) showed adequate weight gain, and 56% (71 of 127) showed excessive weight gain. Of 127 patients, 27 (21%) had small-for-gestational-age infants. This peaked in the group with insufficient weight gain (47%; 95% confidence interval [CI], 29%-65%; P < .001). The prevalence of large-for-gestational-age infants was comparable between groups, although highest in the group with excessive weight gain (0% in those with insufficient weight gain, 4% in those with adequate weight gain, and 8% in those with excessive weight gain). Preterm births were recorded more in patients with insufficient weight gain (23%; 95% CI, 8%-38%; P = .048). The mean amounts of postpartum weight retained were 4.0 kg (SD, 7.4) at 6 weeks and 3.0 kg (SD, 9.1) at 6 months. Weight retention at 6 weeks (7.1 kg; 95% CI, 5.5-8.7; P < .001) and 6 months (8.3 kg; 95% CI, 4.5-12.2; P < .001) was highest in women gaining excessive weight. CONCLUSION Achievement of IOM guidelines is low in postbariatric pregnancies. Insufficient weight gain increases the risk for small-for-gestational-age babies. Excessive weight gain increases weight retention after delivery and could precipitate weight regain. After bariatric surgery, women should be encouraged to achieve IOM recommendations.

Abstract
INTRODUCTION/AIM Children experience important anxiety before surgery. Anxiety and pain are positively correlated. Serious gaming is a non-pharmacological intervention to prepare children and parents for an operation. We aimed to evaluate the effectiveness of the serious game CliniPup® on anxiety and pain in children undergoing ambulatory surgery. METHOD A prospective randomized controlled pilot trial in 72 children aged 5 to 11 years old scheduled for day-care surgery (general surgery, dentistry, otorhinolaryngology, urology) was performed. Participants were randomly assigned into 3 groups: A (CliniPup®), B ("Empty game" without educational information), or C (no game, oral information at the outpatient clinic, current standard of care). Anxiety, pain, and behaviour were evaluated by validated instruments at six time-points: T0: baseline, T1: 1 week preoperatively, T2: at hospital admission, T3: before discharge, T4: 1 week postoperatively, T5: 1 month postoperatively. RESULTS After playing the game (T1), the estimated mean anxiety score (VASa) was lower in Group A (1.9 units) versus Group B (2.7 units). The estimated mean VASa at T1 for Group A was 2.6 units lower compared to Group C (p = 0.003). For Group B, VASa levels were 1.8 units lower than in Group C (p = 0.045). After correction for "surgery type", Group A continued to show a significantly lower VASa compared to Group C (p = 0.044). On the other time points, no difference in anxiety and pain were observed, nor in post-hospitalization behaviour. CONCLUSION Children that played the CliniPup® game one week before surgery had a significant reduction in preoperative anxiety after playing the game, but not on the other time points. No differences on peri-operative pain were observed during the different time points. TYPE OF STUDY Randomized Trial. LEVEL OF EVIDENCE Level II.

Perioperative bridging of anticoagulation: towards a more reserved approach. Neth J Med 2019; 77:280-286.

Abstract
BACKGROUND Most invasive procedures require the interruption of oral anticoagulation. In 2015, an international randomised trial demonstrated that perioperative bridging caused more harm than benefit in most anticoagulated patients with atrial fibrillation, leading to a more restrictive Dutch national guideline in April 2016. The objective of the present study was to analyse the integration of the 2016 Dutch guideline for perioperative antithrombotic management from after publication until update of hospital protocols. METHODS This is a retrospective cohort study of patients on vitamin K antagonists undergoing a surgical procedure between April 2016 and June 2017. RESULTS The proportion of high-risk patients with venous thromboembolism or atrial fibrillation receiving bridging therapy decreased from 91% and 77%, respectively at the start of the study to 33% in both groups in the last months. In high-risk patients with a mechanical heart valve, the bridging rate remained stable at 70-80% for 12 months and increased to 100% in the last 3 months. Protocol adherence for high-risk patients decreased from 80% to below 43%. The 30-day incidence of major bleeding was 4.1% (15.2% in bridged patients and 0.7% in non-bridged patients) and 10.3% for clinically relevant non-major bleeding (23.9% in bridged patients and 6.0% in non-bridged patients). The incidence of thrombo-embolism was 0.5%. CONCLUSION New evidence from the Dutch national guideline on perioperative bridging was adopted by physicians before the local hospital protocol was updated. Low incidence of thromboembolism in non-bridged patients and high incidence of bleeding in bridged patients support a more restrictive bridging policy.

Abstract
Viral rebound upon stopping combined antiretroviral therapy poses a major barrier toward an HIV cure. Cellular and anatomical sources responsible for reinitiating viral replication remain a subject of ardent debate, despite extensive research efforts. To unravel the source of rebounding viruses, we conducted a large-scale HIV-STAR (HIV-1 sequencing before analytical treatment interruption to identify the anatomically relevant HIV reservoir) clinical trial. We collected samples from 11 participants and compared the genetic composition of (pro)viruses collected under treatment from different cellular and anatomical compartments with that of plasma viruses sampled during analytical treatment interruption. We found a remarkably heterogeneous source of viral rebound. In addition, irrespective of the compartment or cell subset, genetically identical viral expansions played a significant role in viral rebound. Our study suggests that although there does not seem to be a primary source for rebound HIV, cellular proliferation is an important driver of HIV persistence and should therefore be considered in future curative strategies.

Abstract
Background Chronic kidney disease (CKD) in childhood is poorly explained by routine markers (e.g. urea and creatinine) and is better depicted in adults by other uraemic toxins. This study describes concentrations of representative uraemic toxins in non-dialysis CKD versus healthy children. Methods In 50 healthy children and 57 children with CKD Stages 1-5 [median estimated glomerular filtration rate 48 (25th-75th percentile 24-71) mL/min/1.73 m2; none on dialysis], serum concentrations of small solutes [symmetric and asymmetric dimethyl-arginine (SDMA and ADMA, respectively)], middle molecules [β2-microglobuline (β2M), complement factor D (CfD)] and protein-bound solutes [p-cresylglucuronide (pCG), hippuric acid (HA), indole-acetic acid (IAA), indoxyl sulphate (IxS), p-cresyl sulphate (pCS) and 3-carboxy-4-methyl-5-propyl-furanpropionic acid (CMPF)] were measured. Concentrations in the CKD group were expressed as z-score relative to controls and matched for age and gender. Results SDMA, CfD, β2M, IxS, pCS, IAA, CMPF and HA concentrations were higher in the overall CKD group compared with controls, ranging from 1.7 standard deviations (SD) for IAA and HA to 11.1 SD for SDMA. SDMA, CfD, β2M, IxS and CMPF in CKD Stages 1-2 with concentrations 4.8, 2.8, 4.5, 1.9 and 1.6 SD higher, respectively. In contrast, pCS, pCG and IAA concentrations were only higher than controls from CKD Stages 3-4 onwards, but only in CKD Stage 5 for ADMA and HA (z-score 2.6 and 20.2, respectively). Conclusions This is the first study to establish reference values for a wide range of uraemic toxins in non-dialysis CKD and healthy children. We observed an accumulation of multiple uraemic toxins, each with a particular retention profile according to the different CKD stages.

Abstract
Background: Ambulatory surgery for anorectal procedures has become widely accepted. Recent reviews recommend a multimodal approach to pain management. However, these recommendations are largely based on single intervention studies. Our goal was to evaluate post-operative pain in patients receiving a multimodal analgesic regimen. Methods: All patients undergoing an ambulatory anorectal procedure between December 2015 and September 2016 received a pain diary. Mean pain throughout the day and pain during defecation where recorded on day 0-14 and day 21 postoperatively using a numeric rating scale-11. Use of oral analgesics was also recorded. Results: Forty-two patients completed the pain diary. The use of local anesthetic infiltration did not result in a significant difference in pain scores in this study. Patients who received written information on postoperative pain management and hygienic measures had higher intake of oral analgesics. Despite receiving multimodal analgesic treatment, patients undergoing surgery for hemorrhoids or anal fissures reported pain scores ≥4 and used analgesics longer. Conclusion: A multimodal analgesic approach consisting of local anesthetic infiltration, multiple oral analgesics and written information seems to be insufficient for certain patient groups after ambulatory anorectal surgery. Especially patients undergoing surgery for hemorrhoids or an anal fissure should receive adequate analgesia. Pain during defecation is problematic and finding a solution for this problem remains challenging. Further research into the combined use of different analgesic modalities is recommended.

Abstract
BACKGROUND Advantages of ambulatory surgery are lost when patients need an unplanned admission. This retrospective cohort study investigated reasons for failed discharge and unanticipated admission of adult patients after day surgery. METHODS Ambulatory patients (n = 145) requiring unanticipated admission were compared to patients (n = 4980) not requiring admission and timely discharged from a total of 5156 ambulatory surgical procedures. Demographic data, organisational data, reason for admission, type of anesthesia, surgical discipline, length of procedure, ASA classification, surgical completion time and severity of illness score were collected from both groups. Reason for admission was classified according to four subtypes. Logistic regression analysis was used. RESULTS Incidence of unanticipated admission following day care surgery was 2.89%. The reasons for admission were mainly organisational issues (45.52%), time of completion surgery in the afternoon between 12 pm and 3 pm (OR 1.73; 95% CI 1.05-2.86) and surgery that ends after 3 pm (OR 6.52; 95% CI 4.11-10.34). Surgical factors associated with unanticipated admission (38.62%) were length of surgery of one to three hours (OR 2.05; 95% CI 1.27-3.29), length of surgery more than three hours (OR 8.31; 95% CI 3.56-19.40). Additionally, anaesthetic (10.34%) and medical (5.52%) reasons were found, e.g. ASA class II (OR 1.61; 95% CI 1.06-2.44), ASA class III (OR 2.19; 95% CI 1.10-4.34); moderate severity of illness score (OR 1.72; 95% CI 1.03-2.88) and major of severity of illness score (OR 7.85; 95% CI 2.31-26.62). CONCLUSIONS Unanticipated admissions following day surgery occur mainly due to social/organisational and surgical reasons. However, medical and anaesthetic reasons also explain 15.86% of the unanticipated admissions.

Abstract
Background Double-blind, placebo-controlled food challenge (DBPCFC) is considered the gold standard for food allergy diagnosis. However, this test is rarely performed routinely in clinical practice because of various practical issues, e.g. the lack of a standardized matrix preparation. The aim of this study was to develop and validate a convenient DBPCFC matrix, that can easily be implemented in daily clinical practice. The focus of this study was the blinding of hazelnuts, whereby the hazelnuts retained as much as possible their allergenicity and could be mixed homogenously in low-doses to the matrices. Methods A basophil-activation test (BAT), microbial tests and an LC-MS/MS test were performed to assess respectively the allergenicity of the used hazelnuts, the microbial stability of the novel developed matrices and the homogeneity of the hazelnuts in the matrices. A sensory test was conducted to validate the blinding of the hazelnuts in the matrices. A pilot DBPCFC study included eight patients as proof of concept. Results The BAT-test gave the first insights concerning the retained allergenicity of the hazelnuts. The microbial safety could be assured after 12 months of storage. Sufficient masking was assessed by several sensory tests. Homogeneous hazelnut distribution could be achieved for the different hazelnut concentrations. The DBPCFC’s results showed diverse allergic responders (from no reactions to distinct objective symptoms). Conclusion A novel stable and validated DBPCFC matrix using raw hazelnuts has been developed that allows easy preparation in a standardized way for convenient use in daily clinical practice.

Abstract
Background The treatment of bleeding disorders improved in the last decades. However, the effect of growing up with bleeding disorders on developmental, emotional, and social aspects is understudied. Therefore, this study assesses HRQOL, developmental milestones, and self-esteem in Dutch young adults (YA) with bleeding disorders compared to peers. Methods Ninety-five YA (18–30 years) with bleeding disorders (78 men; mean 24.7 years, SD 3.5) and 17 women (mean 25.1 years, SD 3.8) participated and completed the Pediatric Quality of Life Inventory Young Adult version, the Course of Life Questionnaire, and the Rosenberg Self-Esteem Scale. Differences between patients with bleeding disorders and their peers, and between hemophilia severity groups, were tested using Mann–Whitney U tests. Results YA men with bleeding disorders report a slightly lower HRQOL on the total scale, physical functioning, and school/work functioning in comparison to healthy peers (small effect sizes). YA men with severe hemophilia report more problems on the physical functioning scale than non-severe hemophilia. YA men with bleeding disorders achieved more psychosexual developmental milestones than peers, but show a delay in ‘paid jobs, during middle and/or high school.’ A somewhat lower self-esteem was found in YA men with bleeding disorders in comparison to peers (small effect size). For YA women with bleeding disorders, no differences were found on any of the outcomes in comparison to peers. Conclusion This study demonstrates some impairments in HRQOL and self-esteem in YA men with bleeding disorders. By monitoring HRQOL, problems can be identified early, especially with regard to their physical and professional/school functioning.

Abstract
BACKGROUND Direct oral anticoagulants (DOACs) are an alternative for vitamin K antagonists (VKA) in the treatment and prevention of venous thromboembolism (VTE). Patient preferences for treatment options have not been extensively explored. METHODS A random sample of 200 patients was obtained from those treated with VKA for deep vein thrombosis, pulmonary embolism or both at the Thrombosis Service Amsterdam. Preference for DOACs relative to VKA was assessed using a treatment trade-off technique administered as a questionnaire sent to all patients. The trade-off consisted of four consecutive scenarios: 1 (no need for laboratory control), 2 (decreased bleeding risk), 3 (less interactions with food and other drugs), 4 (higher efficacy). RESULTS The response rate was 68%. In scenario 1, 36% of patients would switch to a DOAC. This proportion rises to 57% (odds ratio [OR] 2.3; 95% confidence interval [CI] 1.6-3.3) for scenario 2. Scenario 3 resulted in 64% of patients preferring a DOAC (OR 3.2; 95%CI 2.2-4.6). The advantage of greater efficacy did not result in a noteworthy change in the preference. Patients who were less satisfied with their current treatment, who were younger and those with higher education were more likely to prefer a DOAC over a VKA. The variables gender, treatment duration, and type of VKA were not significantly associated with DOAC preference. CONCLUSION Almost two-thirds of patients preferred DOACs over VKA. Patients considered the lack of regular laboratory monitoring, the lower risk of serious bleeding and less interactions with food and other drugs the most important arguments to switch to a DOAC.

Abstract
Background The expansion of the obesity epidemic is accompanied with an increase in bariatric procedures, in particular in women of reproductive age. The weight loss induced by the surgery is believed to reverse the negative impact of overweight and obesity on female reproduction, however, research is limited to in particular retrospective cohort studies and a growing number of small case-series and case-(control) studies. Methods/design AURORA is a multicenter prospective cohort study. The main objective is to collect long-term data on reproductive outcomes before and after bariatric surgery and in a subsequent pregnancy. Women aged 18–45 years are invited to participate at 4 possible inclusion moments: 1) before surgery, 2) after surgery, 3) before 15 weeks of pregnancy and 4) in the immediate postpartum period (day 3–4). Depending on the time of inclusion, data are collected before surgery (T1), 3 weeks and 3, 6, 12 or x months after surgery (T2-T5) and during the first, second and third trimester of pregnancy (T6-T8), at delivery (T9) and 6 weeks and 6 months after delivery (T10-T11). Online questionnaires are send on the different measuring moments. Data are collected on contraception, menstrual cycle, sexuality, intention of becoming pregnant, diet, physical activity, lifestyle, psycho-social characteristics and dietary supplement intake. Fasting blood samples determine levels of vitamin A, D, E, K, B-1, B-12 and folate, albumin, total protein, coagulation parameters, magnesium, calcium, zinc and glucose. Participants are weighted every measuring moment. Fetal ultrasounds and pregnancy course and complications are reported every trimester of pregnancy. Breastfeeding is recorded and breast milk composition in the postpartum period is studied. Discussion AURORA is a multicenter prospective cohort study extensively monitoring women before undergoing bariatric surgery until a subsequent pregnancy and postpartum period. Trial registration Retrospectively registered (July 2015 - NCT02515214)

Abstract
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety of anticoagulants are unknown in this setting and based on sparse and low-quality observational data. Objectives Our aim was to estimate the incidence of thromboembolic, bleeding and anticoagulant-related complications in HPN patients, and evaluate risk factors for first venous thrombosis (VT). Methods This retrospective cohort study included all adult patients followed for long-term HPN at our center between 1986 and 2014. Primary outcomes were symptomatic objectively diagnosed VT, encompassing CRT and venous thromboembolism, and major bleeding. Secondary outcomes were vena cava syndrome and heparin-induced thrombocytopenia or hypersensitivity. Results A total of 236 patients were included (median HPN duration, 17 months) and 136 received anticoagulants at HPN onset (57.6%). Overall, the annual incidence of first VT was 11.4% (95% confidence interval [95% CI], 8.6-14.7%); VT was associated with a personal history of thrombosis (adjusted hazard ratio, 2.22; 95% CI, 1.06-4.64), whereas anticoagulation seemed to account only for a mild protection (adjusted hazard ratio, 0.72; 95% CI, 0.36-1.44). The annual incidence of major bleeding was 4.3% for patients on anticoagulants vs. 1.8% for those off anticoagulants. Vena cava syndrome developed in 20.7% of patients with VT. One patient had isolated heparin-induced thrombocytopenia (0.6%) and four had heparin hypersensitivity (2.5%). Conclusions Patients on HPN have a significant risk of venous thrombosis, major bleeding and vena cava syndrome. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain.

In vivo increase in thrombin generation by four-factor prothrombin complex concentrate in apixaban-treated healthy volunteers. J Thromb Haemost 2015; 13:1799-805. [PMID: 26270625 DOI: 10.1111/jth.13115] [Citation(s) in RCA: 56] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2015] [Accepted: 08/02/2015] [Indexed: 01/05/2023]
Abstract
BACKGROUND Four-factor prothrombin complex concentrate (PCC) (Cofact; Sanquin Blood Supply) 50 IU kg(-1) increased thrombin generation beyond baseline values in healthy, rivaroxaban-treated subjects. OBJECTIVE To assess whether infusion with doses of 37.5 IU kg(-1) and 25 IU kg(-1) PCC reverses the anticoagulant effect of high-dose apixaban, another oral direct factor Xa inhibitor. METHODS In a randomized, double-blind, placebo-controlled, crossover study, six healthy subjects received twice-daily apixaban 10 mg for 3.5 days followed by a single bolus of 37.5 IU kg(-1) PCC, 25 IU kg(-1) PCC, or placebo. The primary outcome was the effect of PCC 15 min after infusion on thrombin generation (endogenous thrombin potential [ETP]); secondary outcomes were the immediate effect of PCC on prothrombin time (PT) and the effect of PCC as compared with placebo over a period of 24 h on ETP and PT. RESULTS Fifteen minutes after infusion of 37.5 IU kg(-1) and 25 IU kg(-1) PCC, ETP increased from 41% ± 11% to 56% ± 23% (P = 0.06) and from 44% ± 12% to 51% ± 15% (P = 0.03), respectively. ETP significantly differed over time between 37.5 IU kg(-1) PCC and placebo during 24 h after infusion (P < 0.01). Both PCC doses restored apixaban-induced PT prolongation after 15 min (P < 0.01), and this was sustained over a period of 24 h. CONCLUSION Both 37.5 IU kg(-1) PCC and 25 IU/kg PCC improved coagulation parameters in healthy subjects, suggesting partial reversal of the anticoagulant effect of apixaban. This implies that PCC might be considered in patients with apixaban-associated bleeding. However, ETP was not immediately restored to pre-apixaban levels, suggesting that these doses are too low to instantly and fully restore hemostasis at peak apixaban levels.

Combined spinal epidural analgesia for labor using sufentanil epidurally versus intrathecally: a retrospective study on the influence on fetal heart trace. J Perinat Med 2015; 43:481-4.

Abstract
OBJECTIVE We retrospectively compared a protocol using sufentanil and ropivacaine intrathecally with a protocol in which only ropivacaine was administered intrathecally and sufentanil was used epidurally to evaluate whether banning sufentanil from the intrathecal space results in a decreased incidence of adverse fetal heart rate changes. METHODS Some 520 cardiotocographic tracings were examined for changes in fetal heart rate and uterine activity following two different protocols of combined spinal epidural analgesia. Charts were consulted for neonatal and labor outcome. RESULTS When sufentanil was used epidurally instead of intrathecally, the incidence of adverse changes in fetal heart trace was less, demonstrated by a higher percentage of normal reassuring tracings (74.5% vs. 60.4% when sufentanil was used intrathecally; P=0.007), less tracings showing bradycardia (7.5% vs. 14.1%; P=0.035), and more tracings displaying 3 or more accelerations in fetal heart rate in 45 min (93.5% vs. 83.9%; P=0.003) together with less episodes of tachycardia (3.5% vs. 11.4%; P=0.005). There were no differences in labor and neonatal outcome. CONCLUSIONS Based on fetal heart tracing, it seems favorable to ban sufentanil from the intrathecal compartment.

Decreased plasma levels of activated factor VII in patients with deep vein thrombosis. J Thromb Haemost 2015; 13:1320-4.

Abstract
BACKGROUND The initiating trigger in the development of deep vein thrombosis (DVT) remains unidentified. It has been suggested that tissue factor (TF)-bearing microparticles play a key role, which indicates a role for the TF pathway in the initiation of DVT. OBJECTIVE To assess the role of the TF pathway in the initiation of venous thrombosis, we measured plasma levels of factor VII and VIIa in patients with acute DVT and in controls. METHODS We included 148 patients diagnosed with acute DVT and 179 controls in this study. Antigen levels of FVII and FVIIa were measured by using assays recently developed in our laboratory. RESULTS Median FVII levels in patients were 109.8% (interquartile range [IQR] 86.0-153.2) compared with 102.2% (IQR 76.1-141.7) in controls. Individuals with FVII levels in the upper quartile had a 1.6-fold increased risk for the presence of a DVT (odds ratio 1.6, 95% confidence interval 0.8-3.1). Median FVIIa levels in patients were 50.2 ng mL(-1) (IQR 25.2-86.1) compared with 96.6 ng mL(-1) (69.9-168.9) in controls. Individuals with FVIIa levels in the lowest quartile had a > 5-fold increased risk for the presence of a DVT (odds ratio 5.5, 95% confidence interval 2.8-10.6). Both risks did not change substantially after adjustment for potential confounders. CONCLUSION Decreased plasma levels of FVIIa in patients with deep vein thrombosis may indicate ongoing consumption of FVIIa and suggest a contributory role for TF in venous thrombus formation.

Real-world variability in dabigatran levels in patients with atrial fibrillation. J Thromb Haemost 2015; 13:353-9. [PMID: 25523236 DOI: 10.1111/jth.12823] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2014] [Accepted: 12/14/2014] [Indexed: 08/31/2023]
Abstract
BACKGROUND In clinical practice, physicians are given the choice of selecting one of two dabigatran doses based on patient characteristics, with the lower dose typically used in patients at a higher risk of bleeding. OBJECTIVES The objectives of the study were to (i) estimate the inter- and intra-patient variability in dabigatran levels with 110 mg (DE110) and 150 mg (DE150) doses, (ii) examine the effect of physicians' dose selection on levels in DE110 and DE150 subgroups, and (iii) explore whether a single trough measurement identifies patients with extreme levels on subsequent visits. METHODS In this prospective observational study of 100 patients with atrial fibrillation (AF), peak and trough levels of dabigatran were measured with the Hemoclot(®) assay at baseline and every 2 months thereafter (maximum four visits). RESULTS Inter-patient variability in dabigatran levels (geometric coefficient of variation [gCV], 51-64%) was greater than intra-patient variability (gCV, 32-40%). Similar medians and distributions of levels were observed in DE110 and DE150 subgroups. Patients receiving DE110 were older, had lower renal function and weighed less than those receiving DE150. Up to 40% of patients whose trough levels were in the upper extremes, and up to 80% of patients whose trough levels were in the lower extremes at baseline, showed subsequent levels that fell in the middle quartiles. CONCLUSIONS Our data support the practice of selecting the dabigatran dose based upon clinical characteristics because it results in similar levels of drug exposure in patients given DE110 or DE150. They do not support the concept that a single Hemoclot(®) measurement reliably identifies patients with consistently high or low values.

Abstract
Children undergoing medical or surgical treatment for ENT disorders should receive care from doctors familiar with the specificities of paediatric ENT pathology working in dedicated clinics where there are facilities for the activities that children usually indulge in and accommodation for parents. Many aspects of care for children with ENT problems involve a multidisciplinary team consisting of ENT surgeons working alongside a range of medical and paramedical professionals and nurses specifically trained in childcare, as well as in ENT nursing. Within this multidisciplinary approach, we will discuss some important aspects of the psychosocial approach and nursing, anaesthesia and pharmacotherapy that should be considered in order to raise the safety and quality of patient care in paediatric otorhinolaryngology.

Risk factors of arterial cardiovascular complications in patients with prior venous thromboembolism. Neth J Med 2011; 69:27-30.

Abstract
BACKGROUND The effect of cardiovascular risk factors (CVRs) and thrombophilic defects on the risk of arterial cardiovascular complications in patients with prior venous thromboembolism (VTE) is unclear. OBJECTIVE We investigated whether the risk of arterial cardiovascular complications is increased after VTE and whether CVRs and thrombophilic defects influence this risk. METHODS Subjects were selected from three family cohorts of probands with VTE or arterial cardiovascular complication before the age of 50 and thrombophilic defects (i.e. hyperhomocysteinaemia, prothrombin G20210A or elevated FVIII). For this analysis, probands with arterial cardiovascular complications before inclusion and their relatives as well as relatives without the studied thrombophilic defects were excluded. We calculated the incidence of arterial cardiovascular complications (e.g. myocardial infarction, ischaemic stroke, transient ischaemic attack or peripheral arterial disease) in subjects with and without VTE and adjusted the relative risk for at least one CVR, two or more thrombophilic defects and quintiles of a propensity score (considering risk factors conditional to VTE history). RESULTS 861 subjects were included, of whom 399 had experienced VTE before inclusion. Twelve arterial cardiovascular complications occurred in subjects with and nine in subjects without VTE history. Hence the annual incidence was 1.0 (95% CI 0.5 to 1.7) and 0.7 (0.3 to 1.2) in subjects with and without VTE (RR 1.5, 0.6 to 3.6). Adjusting for possible confounders did not change this relative risk. CONCLUSION The mildly elevated risk of arterial cardiovascular complications in patients with prior VTE appears to be independent of cardiovascular risk factors and thrombophilic defects.
