Background: There is a higher risk of gastrointestinal (GI) bleeding in patients treated with dabigatran versus warfarin. We analyzed the impact of renal function on the relative risk of bleeding in patients converted to dabigatran. Methods: Patients aged ≥65 years who received anticoagulation with warfarin for a minimum of 6 months and subsequently converted to dabigatran or remained on warfarin were studied. Data sources included VA National Patient Care, and VA Decision Support System National Pharmacy and Laboratory. Each patient who converted to dabigatran 150 mg twice daily was matched by propensity score with 2 patients on warfarin who did not convert. Outcomes included rates of hospital admission for GI or other major bleeding and mortality, stratified by estimated glomerular filtration rate (eGFR). Results: Study population included 864 patients who converted and 1,710 patients who did not convert to dabigatran. In patients with eGFR 50-80 ml/min/1.73 m², the hazard of GI bleeding in patients who initiated dabigatran was nearly 3 times higher, (4.1 vs. 1.3 per 100 patient years; hazards ratio 2.94; 95% CI 1.24-7.02; p = 0.015), compared to patients who remained on warfarin. There were relatively few patients with eGFR <50 or >80 ml/min/1.73 m2, and relatively few bleeding events outside the GI tract. Conclusions: Prescribing healthcare providers should exercise caution and close monitoring for bleeding complications when converting from warfarin to dabigatran, even in patients with renal function in the range considered safe for dabigatran use as per current recommendations.

The Impact

This study attempted to identify the impact of internal work environment on the retention of healthcare providers at Turaif General Hospital in the Kingdom of Saudi Arabia. In particular, the study aimed to identify the dimensions of work circumstances, compensation, and relationship with colleagues, professional growth, and the level of healthcare providers’ retention. In order to achieve the study goals, the researcher used the descriptive analytical approach. The researcher used the questionnaire as the study tool. The study population comprised all the healthcare providers at Turaif General Hospital. Questionnaires were distributed to the entire study sample that consisted of 220 individuals. The number of questionnaires valid for study was 183 questionnaires. The research findings were as follows: the participants’ estimate of the work circumstances dimension was high (3.64), the participants’ estimate of the compensation dimension was moderate (3.32), the participants’ estimate of the relationship with colleagues dimension was high (3.62), the participants’ estimate of the professional growth dimension was weak (2.39), and the participants’ estimate of healthcare providers’ retention level was intermediate (2.75). Accordingly, the researcher’s major recommendations are: the need to create the right atmosphere for personnel in hospitals, the interest of the hospital to provide the appropriate conditions for the staff in terms of the physical and moral aspects for building the work adjustment in the staff, and conducting training courses and educational lectures for personnel in hospitals on how to cope with the work pressures.

The Impact

Additional loading dose of acetylsalicylic acid (ASA) during percutaneous coronary interventions (PCIs) despite permanent oral ASA medication is frequently applicated. The impact on platelet reactivity and clinical events is not known. In this pilot study, we aimed to analyze high on-treatment platelet reactivity (HTPR) to aspirin in patients undergoing elective PCI. Platelet reactivity was measured using light-transmission aggregometry in 100 patients on permanent low-dose ASA medication undergoing elective PCI. Platelet reactivity measured by arachidonic acid-induced maximum of aggregation (MoA) in patients with versus without additional peri-procedural ASA loading (500 mg i.v.) was compared. HTPR was defined as MoA &#x3e;20% for ASA. Major adverse cerebro- and cardiovascular events (MACCEs) and bleeding events were evaluated during hospital course. HTPR rate was similar in both groups (HTPR to ASA: loading vs. control 6% vs. 16%, odds ratio [OR] = 0.33, 95% confidence interval [CI] 0.08–1.35, <i>p</i> = 0.12). In-hospital MACCEs were not different between groups (MACCE: loading vs. control: 0 vs. 0 patient, OR = 1.32, 95% CI 0.03–67.95, <i>p</i> = 0.89). Thrombolysis in myocardial infarction minimal bleedings were numerically higher in patients without ASA loading dose. In this pharmacodynamic pilot study, additional ASA loading did not reduce HTPR to ASA. Furthermore, ASA loading did not increase in-hospital MACCE and bleeding complications.

Purpose. The purpose of the study was to evaluate the influence of a continued antiplatelet therapy with clopidogrel on postoperative bleeding risk in patients undergoing skin tumor resection and reconstruction with local flaps or skin grafts under outpatient conditions.Patients and Methods. The authors designed and implemented a retrospective clinical cohort study at the General Hospital Balingen. The primary endpoint was the bleeding ratio in patients with clopidogrel treatment in comparison to patients without any anticoagulant or antiplatelet therapy. Wound healing was evaluated on days 1, 3, 5, 7, 10, and 14.Results. 650 procedures were performed, 123 of them under continued clopidogrel therapy. There were significantly more postoperative bleeding complications among patients with continued antiplatelet therapy. Regarding the whole study population, malignant lesions, a larger defect size, and skin grafts were accompanied by a higher rate of bleeding incidents. However, there were no significant findings in the univariate analysis of the clopidogrel group. All bleeding incidents were easily manageable.Conclusion. Despite an increased bleeding ratio among patients under continued clopidogrel therapy, the performance of simple surgical procedures can be recommended. However, cautious preparation and careful hemostasis are indispensable.

Background: Previous reports are conflicting regarding outcomes, treatments, and processes of care after acute myocardial infarction (MI) for patients with chronic lung disease (CLD). Methods: Using the NCDR ACTION Registry ® -GWTG ™ (AR-G), demographics, clinical characteristics, treatments, processes of care, and in-hospital adverse events after NSTEMI and STEMI were compared between patients with (n= 22,624; 14.2%) and without (n= 136,266; 85.8%) CLD. CLD was defined by a history of COPD, chronic bronchitis, or emphysema. Multivariable adjustment using published AR-G in-hospital mortality and major bleeding risk adjustment models was performed to quantify the impact of CLD on treatments and outcomes. Results: CLD was present in 10.1% of STEMI patients and 17.0% of NSTEMI patients. In both STEMI and NSTEMI, CLD patients were older, more likely to be female, and had more comorbidities including diabetes, renal disease, prior MI and heart failure, compared to those without CLD. Although on admission CLD patients were more likely to be on cardiovascular medications, by discharge slightly fewer CLD patients received composite core measures (aspirin, beta-blockers, ACE-inhibitors, and statins) (table). In NSTEMI, CLD was also associated with less use of invasive procedures and with increased risk of both death and major bleeding. In STEMI, major bleeding but not mortality was increased. Conclusions: CLD is a common comorbidity and is independently associated with an increased risk for major bleeding after MI. In NSTEMI, CLD is also associated with receiving fewer evidence-based medications, less timely angiography and revascularization, and increased in-hospital mortality. Close attention should be given to this high-risk subgroup for the prevention and management of bleeding complications after MI, and further investigation is needed to determine the reasons for treatment and outcome disparities in NSTEMI.

Abstract Aims Patients with atrial fibrillation undergoing coronary intervention are at higher bleeding risk due to the concomitant need for oral anticoagulation and antiplatelet therapy. The RE-DUAL PCI trial demonstrated better safety with dual antithrombotic therapy (DAT: dabigatran 110 or 150 mg b.i.d., clopidogrel or ticagrelor) compared to triple antithrombotic therapy (TAT: warfarin, clopidogrel or ticagrelor, and aspirin). We explored the impact of baseline bleeding risk based on the PRECISE-DAPT score for decision-making regarding DAT vs. TAT. Methods and results A score ≥25 points qualified high bleeding risk (HBR). Comparisons were made for the primary safety endpoint International Society of Thrombosis and Haemostasis major or clinically relevant non-major bleeding, and the composite efficacy endpoint of death, thrombo-embolic events, or unplanned revascularization, analysed by time-to-event analysis. PRECISE-DAPT was available in 2336/2725 patients, and 37.9% were HBR. Compared to TAT, DAT with dabigatran 110 mg reduced bleeding risk both in non-HBR [hazard ratio (HR) 0.42, 95% confidence interval (CI) 0.31–0.57] and HBR (HR 0.70, 95% CI 0.52–0.94), with a greater magnitude of benefit among non-HBR (Pint = 0.02). Dual antithrombotic therapy with dabigatran 150 mg vs. TAT reduced bleeding in non-HBR (HR 0.60, 95% CI 0.45–0.80), with a trend toward less benefit in HBR patients (HR 0.92, 95% CI 0.63–1.34; Pint = 0.08). The risk of ischaemic events was similar on DAT with dabigatran (both 110 and 150 mg) vs. TAT in non-HBR and HBR patients (Pint = 0.45 and Pint = 0.56, respectively). Conclusions PRECISE-DAPT score appeared useful to identify AF patients undergoing PCI at further increased risk of bleeding complications and may help clinicians identifying the antithrombotic regimen intensity with the best benefit–risk ratio in an individual patient.

BACKGROUND: Bleeding is a common and costly complication of percutaneous coronary intervention (PCI). Little is known about the risk factors for bleeding complications. Objective: To report our PCI-related observations from a single institution and use the information to establish risk factors for short-term bleeding complications, with special focus on examining the importance of renal function. METHODS: A retrospective record review was conducted of the admission of 300 patients grouped according to antithrombotic regimen: unfractionated heparin alone (n = 187), bivalirudin (n = 26), and glycoprotein IIb/IIIa antagonist plus heparin (n = 103). Bleeding and ischemic outcomes were tracked. A model was constructed to predict independent bleeding risk factors. RESULTS: Treatment groups differed significantly regarding any bleeding (p = 0.001), minor bleeding (p < 0.001), and length of stay (p = 0.01). Multivariate predictors of any bleeding included antithrombotic regimen, creatinine clearance (Clcr) <30 mL/min, and hypertension. Any bleeding was associated with prolonged length of stay. Major bleeding was predicted by Clcr <30 mL/min and was associated with prolonged length of stay and death. Minor bleeding was predicted only by choice of antithrombotic regimen. CONCLUSIONS: The major influences on bleeding risk appeared to be Clcr <30 mL/min and choice of antithrombotic regimen. It is important to note that other markers of renal function, including serum creatinine value and serum creatinine at a cutoff level of 1.5 mg/dL, did not predict bleeding events.

Abstract Backgound: The clinical course of multiple myeloma is often associated with significant bone related morbidity. This can be modified by the use of bisphosphonates. Studies have shown renal toxicity associated with different bisphosphonates especially following the exposure of zoledronic acid. Published literature suggests renal function deterioration occurs in 8.8–15.2% of patients at recommended dose of 4 mg infused intravenously over 15 minutes. Methods: We retrospectively reviewed the records of all patients with multiple myeloma who received bisphosphonates during the period of January 2002-June 2004 at our institution. 114 patients were analyzed (male/female 63/51; age-median 69;mean 71;range 40–92). 61 (54%) were >70 years of age. They received a total of 1301 doses (mean 11.4) during this period. The type of bisphosphonate used was: zolendronate: 58; pamidronate: 23; pamidronate changed to zolendronate (both) : 33. Patients were categorized to the type and sequence of bisphosphonates [ pamidronate vs. zoledronate and pamidronate followed by zoledronate (both) ], age and sex. Renal dysfunction was defined as an increase in serum creatinine of >0.5 mg/dl over baseline. Results: There were 19 patients (16.7%) who developed renal dysfunction. 15 of the 19 episodes (79%) occurred in the 70 years and older group. The table shows the distribution of patients, type of bisphosphonate and the distribution of patients with renal toxicity. Conclusion: This analysis showed increase in renal dysfunction occurs in all ages with use of bisphosphonates. The elderly may be particularly susceptible to this toxicity. Although we have not analyzed the impact of associated comorbidities (including type of multiple myeloma) leading to renal insufficiency in this study, the elderly patients may need more close monitoring of renal function with the use of bisphosphonates.

Abstract Background: The impact of the COVID-19 pandemic on the world is unprecedented, posing greater threats to vulnerable healthcare systems, especially in developing countries. This study aimed to assess the knowledge of dental healthcare providers in Nigeria about the disease and evaluate their responses to the preventive measures necessitated by the disease.Methods: This was an online self-administered questionnaire-based study conducted among Dentists practicing in Nigeria. A message containing the link to the survey was sent widely via social medial platforms and electronic mails to dentists practicing in Nigeria. The data collection was done between the 2nd of June and 3rd of July, 2020.Results: A total of 314 responses was recorded. Fever was the most commonly specified generalized symptom (97.5%), while the use of masks (100%), hand hygiene (99.7%), social distancing (97.7%) and surface cleaning (99.4%) were the most commonly employed general preventive methods. The main identified risk of transmission in the clinic was aerosol generating procedures (98.7%).Conclusion: The general knowledge of dental personnel in our study population appears to be adequate on the common features of COVID-19 but less adequate regarding the less common features. The COVID-19 pandemic has also modified some aspects of dental service delivery but more needs to be done in this regard.Preventive measures against the transmission of COVID-19 in dental practice settings include proper utilization of teledentistry, clinical triage, preprocedural 1% hydrogen peroxide oral rinses, and the use of appropriate PPEs which should always be encouraged.

Abstract Introduction Current clinical guidelines recommend prolonged dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) in patients presenting with acute coronary syndromes (ACS). However, an extended DAPT duration in high-bleeding risk (HBR) patients amplifies the risk of post procedural complications. Hence, clinicians often face the dilemma of prolonging DAPT duration to prevent recurrent ischaemic events at the expense of increasing the incidence of bleeding in high-risk patients. The actual incidence of ischaemic and bleeding events in this particular population is not well elucidated. Purpose To evaluate one-year ischemic and bleeding outcomes following PCI for ACS in a real-world HBR population as defined by the Academic Research Consortium (ARC) consensus document. Methods We included all patients who presented with ACS to a high-volume single PCI centre from 2012 to 2017 and underwent PCI with 2nd generation drug-eluting stent implantation. Patients were classified as HBR if they met ≥1 major or ≥2 minor criteria according to the recent ARC-HBR consensus. The outcomes of interest were major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI), and target lesion revascularization (TLR), and major bleeding events, including both peri-procedural and post-discharge bleeding. All outcomes were assessed at 1-year follow-up. The Kaplan-Meier method was used for time-to-event analyses. Results Out of 6,097 ACS patients included in this analysis, 2,717 (44.6%) fulfilled the ARC-HBR definition. Compared to non-HBR group, HBR patients were more frequently female, older, more likely to have cardiovascular risk factors (e.g., diabetes, hypertension, and hyperlipidemia) and complex coronary artery disease (e.g., multi-vessel disease, bifurcation lesions, and calcification). The 1-year incidence of MACE was significantly higher in HBR patients (16.3% vs. 8.1%, HR 2.16, 95% CI [1.81–2.59], p&lt;0.001) (Figure 1A). This finding was driven by higher rates of all-cause death and MI (Figure 1B). The 1-year incidence of major bleeding was also significantly higher in HBR patients compared to non-HBR (11.1% vs. 3.1%, HR: 3.92, 95% CI 3.10–4.95; p&lt;0.001). Conclusions HBR patients undergoing PCI for ACS are not only subject to bleeding complications but are also at an increased risk for ischemic events and all-cause mortality.

Abstract Introduction Patients with atrial fibrillation (AF) are likely to have multiple co-morbidities and receive anticoagulants after TAVR, which lead to a poor prognosis including bleeding events. Closure time adenosine diphosphate (CT-ADP) is a primary hemostasis point-of-care test used as a surrogate marker of high molecular weight (HMW) multimers defect of Von Willebrand factor (VWF). Our prior studies suggest that prolongation of CT-ADP (&gt;180 seconds) after TAVR is a major determinant of early and late major/life-threatening bleeding complications (MLBCs). Purpose To evaluate the impact of post-procedural CT-ADP &gt;180sec on bleeding events in AF patients. Methods We included 878 patients from our prospective TAVR registry between 2010 and 2019. Bleeding complications were assessed according to the VARC-2 (Valve Academic Research Consortium-2) criteria. Major adverse cardiac and cerebrovascular events (MACCE) was defined as a composite of all-cause death, myocardial infarction, stroke, and heart failure hospitalization within 1-year after TAVR. Ongoing primary haemostasis disorder was defined by post-procedure CT-ADP &gt;180sec. Primary endpoint was the occurrence of MLBCs during the first year and the second endpoint was 1-year MACCE. Results Patients with AF had a higher incidence of all-cause mortality (15% vs. 8%, p=0.002), MACCE (29% vs. 20%, p=0.002), and MLBCs (20% vs. 12%, p=0.001) within 1-year compared to non-AF patients. When the cohort was split into 4 subgroups according to AF and CT-ADP &gt;180sec, patients with AF and CT-ADP &gt;180sec had the highest risk of MLBCs (log-rank test; p&lt;0.001) (Figure). Multivariate Cox regression analysis confirmed that the patients with AF and CT-ADP &gt;180sec had 4.6-fold higher risk of MLBCs within 1 year compared to non-AF patients with CT-ADP ≤180sec (hazard ratio: 4.60; 95% confidence interval: 2.18 - 9.68; p&lt;0.001). Conclusion Among TAVR patients, AF with post-procedural CT-ADP &gt;180 sec was identified as a strong independent predictor of MLBCs at 1-year follow-up. Our study suggest that persistent primary haemostasis disorders contribute to a higher risk of bleeding events particularly in AF patients and may be considered for a tailored and risk-adjusted antithrombotic therapy after TAVR.
