Venous thromboembolism (VTE) is the third most frequent acute cardiovascular syndrome; its annual incidence may reach 1200 cases per 100,000 population aged ≥80 years. Besides age-related increases in predisposing conditions, the ageing process itself shifts the balance between pro and anticoagulant pathways towards a propensity to thrombosis. Evaluation of symptoms and clinical signs of suspected VTE in older adults should take into account ‘physiologic’ age-related cardiopulmonary changes. Using age-adjusted (in patients older than 50 years) D-dimer cut-off levels in combination with low or intermediate clinical probability increases the number of patients in whom PE can reliably be excluded without imaging tests. Age is a key determinant of the bleeding risk under fibrinolytic and anticoagulation treatment. Overall, the new oral anticoagulants are effective and safe in older adults; however, age-related changes in renal and other organ function and drug pharmacokinetics mandate regular monitoring and possible dose adjustments.

Purpose The purpose of this review was to examine the research activity relating to the role of the general practitioner (GP) in managing age-related hearing loss in older adults. Method A literature search of peer-reviewed journal articles published in English was conducted in online bibliographic databases using multiple variations of the keywords “general practitioner” and “hearing.” Results The search strategy identified 3,255 articles. The abstracts of all articles were screened with 124 full-text records subsequently assessed for eligibility. Forty-nine articles met the inclusion criteria and were included in this review. Conclusions For people with hearing loss, the GP can play an instrumental role in guiding appropriate and timely choices for addressing hearing concerns. There are a range of quick, easy, and sensitive methods available to GPs to assist the objective evaluation of hearing. The evidence suggests that implementing hearing screening programs targeting older adults will increase rates of hearing loss detection and subsequently increase the number of patients receiving hearing loss intervention. Education and training appear key to improving GPs’ screening, management, and referral of patients with hearing loss in the primary health care setting.

Venous thromboembolism (VTE) is a multicausal disease which tends to recur. Recurrence can be prevented by anticoagulant treatment albeit at the cost of bleeding. Deciding on the optimal duration of anticoagulation is based on balancing the risk of recurrence and of bleeding in case anticoagulation is continued. Patients with VTE provoked by a transient risk factor have a low risk of recurrence and stopping anticoagulation after 3 months is recommended because the risk of bleeding likely outweighs the risk of recurrence. In patients with unprovoked VTE recurrence is high and indefinite anticoagulation should be considered. However, the majority of these patients will not suffer recurrence but thus far safe identification of low or high patients risk is not possible. Despite considerable advances in the identification of new risk factors for (recurrent) VTE, predicting the risk of recurrence in an individual patient remains a challenge. Measuring D-Dimer as a global coagulation markers and the use of prediction models that integrate clinical characteristics and laboratory markers are the most promising approaches to improve risk assessment and to optimize the duration of anticoagulation. New oral anticoagulants have been studied for treatment of patients with VTE. However, more data on the bleeding risk during extended thromboprophylaxis are needed to decide which patients may indeed benefit from these novel agents.

Indications of non-vitamin K antagonist oral anticoagulants (NOACs), consisting of two types: direct thrombin inhibitor (dabigatran) and direct factor Xa inhibitor (rivaroxaban, apixaban, and edoxaban), have expanded over the last few years. Accordingly, increasing number of patients presenting for surgery are being exposed to NOACs, despite the fact that NOACs are inevitably related to increased perioperative bleeding risk. This review article contains recent clinical evidence-based up-to-date recommendations to help set up a multidisciplinary management strategy to provide a safe perioperative milieu for patients receiving NOACs. In brief, despite the paucity of related clinical evidence, several key recommendations can be drawn based on the emerging clinical evidence, expert consensus, and predictable pharmacological properties of NOACs. In elective surgeries, it seems safe to perform high-bleeding risk surgeries 2 days after cessation of NOAC, regardless of the type of NOAC. Neuraxial anesthesia should be performed 3 days after cessation of NOACs. In both instances, dabigatran needs to be discontinued for an additional 1 or 2 days, depending on the decrease in renal function. NOACs do not require a preoperative heparin bridge therapy. Emergent or urgent surgeries should preferably be delayed for at least 12 h from the last NOAC intake (better if > 24 h). If surgery cannot be delayed, consider using specific reversal agents, which are idarucizumab for dabigatran and andexanet alfa for rivaroxaban, apixaban, and edoxaban. If these specific reversal agents are not available, consider using prothrombin complex concentrates.

SummaryThe aim of the proposed concept is to use anticoagulant therapy in prophylaxis and therapy of thromboembolic events only to an extent that the coagulation activation is just not any longer detectable. It results an individualized anticoagulation tailored to the coagulation activation of the patient (individualized “minimal invasive” anticoagulation). Intensity and control of efficiency are to be monitored by measurement of in vivo coagulation activation, e.g. by D-dimer-antigen measurement. Especially with the use of the new oral anticoagulants such a saver anticoagulant therapy – as far as possible from bleeding risk – could open up new indications, which so far are not used because of safety reasons. More patients at risk could be prevented from thromboembolic events. The proposed concept is based on pathophysiological considerations and own clinical experience. It should be evaluated for efficiency in clinical studies.

Abstract   During the initial phase of the response to COVID-19, concern was raised regarding a potential link with increased risk of stroke. We aimed to explore the incidence of stroke and thrombotic events within our local population with COVID-19 infection who required admission to the Intensive Care Unit (ICU). Methods Retrospective analysis of 57 consecutive patients with a diagnosis of COVID-19 infection admitted to Barnet General Hospital ICU between 6th March and 26th April 2020. Cases were reviewed to establish whether there had been imaging (CT or MRI) confirmed ischaemic stroke, intra-cerebral haemorrhage (ICH), venous sinus thrombosis (VST) or other thrombotic event, including pulmonary embolism (PE). Data was collected on baseline characteristics and blood tests including D-Dimer levels. Statistical analysis was performed using two-tailed t-test and Fischer’s exact test (FET). Findings: Nineteen patients (33%) were age 65 years or older (mean age 69, range 65 to 74 years) and of these 2 patients (10.5%) had imaging confirmed acute ischaemic stroke. In those under 65 (mean age 54, range 29–64 years) there was one confirmed ICH and one VST. The incidence of PE was 21% in both groups. Survival was significantly lower in the age 65 or older group (26.3% versus 63.2%, p = 0.0119 (FET)). Peak recorded D-Dimer levels also appeared to be significantly higher in the age 65 or older group (p = 0.0003, 95% CI 13068.89 to 39858.68). Conclusions and limitations These findings highlight the importance of awareness of risk of thrombotic events, including acute stroke, in older adults with severe Covid-19 infection. It is possible that the incidence of stroke was underestimated, including due to challenges identifying clinical signs of acute stroke and safely obtaining imaging in this population. Further, ideally prospective, studies are required to more clearly elucidate the degree of association between COVID-19 infection and stroke and VST.

Abstract Background Bleeding can be a serious adverse event of endoscopic sphincterotomy (EST). However, the risk of EST bleeding between direct oral anticoagulant (DOAC) users and those who received no antithrombotic agents has not been clarified. This study analyzed the risk factors for bleeding after EST in patients on DOAC and evaluated the Japan Gastroenterological Endoscopy Society (JGES) guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment. Methods We retrospectively analyzed 524 patients treated with EST who received DOAC or no antithrombotic drug from May 2016 to August 2019. We investigated the risk factors for bleeding. DOAC was typically discontinued for ≤ 1-day based on the JGES guideline. Although DOAC therapy recommenced the next morning after EST in principle, the duration of DOAC cessation and heparin replacement were determined by the attending physician based on each patient’s status. Results The number of patients on DOAC (DOAC group) and those not on antithrombotic drug (no-drug group) was 42 (8.0%) and 482 (92.0%), respectively. DOAC was discontinued for ≤ 1-day in 17 (40.0%) patients and for > 1-day in 25 (60.0%). Of the 524 patients, 21 (4.0%) had EST bleeding. The bleeding rate was higher in the DOAC group (14.0%) (p = 0.004). Multivariate analysis showed that bleeding occurred more frequently in patients on DOAC (odds ratio [OR] 3.95, 95% confidence interval [CI] 1.37–11.4, p = 0.011), patients with low platelet counts (< 100,000/µl) (OR 6.74, 95% CI 2.1–21.6, p = 0.001), and elderly patients (> 80 years old) (OR 3.36, 95%CI 1.17–9.65, p = 0.024). Conclusions DOAC treatment, low platelet count, and old age (> 80 years old) are risk factors for EST bleeding. Although the bleeding incidence increased in patients on DOAC who received antithrombotic therapy according to the JGES guidelines, successful hemostasis was achieved with endoscopy in all cases, and no thrombotic events occurred after cessation of DOAC. Thus, the JGES guidelines are acceptable.

The increase in the proportion of elderly people observed in the population is accompanied by an increase in the prevalence of age-related diseases, including atrial fibrillation. In the treatment of such patients it is necessary to discuss the feasibility of prescribing anticoagulants to prevent ischemic stroke and systemic thromboembolism. The article presents scales that are used to assess the risk of thromboembolic complications and the risk of bleeding. The parameters that should be taken into account when prescribing oral anticoagulants to elderly patients are determined, the principles of bleeding risk management are given. The listed risk factors for bleeding, which are modified, potentially modified and not modified. Attention is paid to the description of specific antidotes to oral anticoagulants, the use of which has expanded in recent years, so many health professionals should know the main pharmacological effects of these drugs, be able to assess their anticoagulant effect in critical conditions and optimally cancel if necessary.

Actuality The course of the novel coronavirus disease (COVID-19) is unpredictable. It manifests in some cases as increasing inflammation to even the onset of a cytokine storm and irreversible progression of acute respiratory syndrome, which is associated with the risk of death in patients. Thus, proactive anti-inflammatory therapy remains an open serious question in patients with COVID-19 and pneumonia, who still have signs of inflammation on days 7–9 of the disease: elevated C-reactive protein (CRP)>60 mg/dL and at least two of the four clinical signs: fever >37.5°C; persistent cough; dyspnea (RR >20 brpm) and/or reduced oxygen blood saturation <94% when breathing atmospheric air. We designed the randomized trial: COLchicine versus Ruxolitinib and Secukinumab in Open-label Prospective Randomized Trial in Patients with COVID-19 (COLORIT). We present here data comparing patients who received colchicine with those who did not receive specific anti-inflammatory therapy. Results of the comparison of colchicine, ruxolitinib, and secukinumab will be presented later.Objective Compare efficacy and safety of colchicine compared to the management of patients with COVID-19 without specific anti-inflammatory therapy.Material and Methods Initially, 20 people were expected to be randomized in the control group. However, enrollment to the control group was discontinued subsequently after the inclusion of 5 patients due to the risk of severe deterioration in the absence of anti-inflammatory treatment. Therefore, 17 patients, who had not received anti-inflammatory therapy when treated in the MSU Medical Research and Educational Center before the study, were also included in the control group. The effects were assessed on day 12 after the inclusion or at discharge if it occurred earlier than on day 12. The primary endpoint was the changes in the SHOCS-COVID score, which includes the assessment of the patient’s clinical condition, CT score of the lung tissue damage, the severity of systemic inflammation (CRP changes), and the risk of thrombotic complications (D-dimer) [1].Results The median SHOCS score decreased from 8 to 2 (p = 0.017), i.e., from moderate to mild degree, in the colchicine group. The change in the SHOCS-COVID score was minimal and statistically insignificant in the control group. In patients with COVID-19 treated with colchicine, the CRP levels decreased rapidly and normalized (from 99.4 to 4.2 mg/dL, p<0.001). In the control group, the CRP levels decreased moderately and statistically insignificantly and achieved 22.8 mg/dL by the end of the follow-up period, which was still more than four times higher than normal. The most informative criterion for inflammation lymphocyte-to-C-reactive protein ratio (LCR) increased in the colchicine group by 393 versus 54 in the control group (p = 0.003). After treatment, it was 60.8 in the control group, which was less than 100 considered safe in terms of systemic inflammation progression. The difference from 427 in the colchicine group was highly significant (p = 0.003).The marked and rapid decrease in the inflammation factors was accompanied in the colchicine group by the reduced need for oxygen support from 14 (66.7%) to 2 (9.5%). In the control group, the number of patients without anti-inflammatory therapy requiring oxygen support remained unchanged at 50%. There was a trend to shorter hospital stays in the group of specific anti-inflammatory therapy up to 13 days compared to 17.5 days in the control group (p = 0.079). Moreover, two patients died in the control group, and there were no fatal cases in the colchicine group. In the colchicine group, one patient had deep vein thrombosis with D-dimer elevated to 5.99 µg/mL, which resolved before discharge.Conclusions Colchicine 1 mg for 1-3 days followed by 0.5 mg/day for 14 days is effective as a proactive anti-inflammatory therapy in hospitalized patients with COVID-19 and viral pneumonia. The management of such patients without proactive anti-inflammatory therapy is likely to be unreasonable and may worsen the course of COVID-19. However, the findings should be treated with caution, given the small size of the trial.

Background: A substantial number of patients with non-valvular atrial fibrillation (NVAF) and a CHA₂DS₂-VASc score of 0 (i.e., low-risk group) use oral anticoagulants (OACs). Objective: To investigate the rate and reasons for OAC use in Thai patients with NVAF and having a CHA₂DS₂-VASc score of 0. Materials and Methods: A nationwide observational multicenter registry of patients with NVAF was set up in Thailand. The patients’ demographic and clinical data were recorded on a case record form and then entered into a web-based data collection and management system. Results: One hundred seventy-six patients with NVAF and a CHA₂DS₂-VASc score of 0 were included. The average age was 53.9±8.2 years old, and all patients were male. Forty-six (26.1%) of the patients received OACs. NVAF patients receiving OACs had a longer duration of AF, more persistent and permanent AF, and mild left ventricular dysfunction. NVAF patients not receiving OACs were significantly more likely to be taking antiplatelet drugs. The reasons for using OACs in patients with a CHA₂DS₂-VASc score of 0 included thrombus in the left atrial appendage, post-AF ablation, planned cardioversion, hypertrophic cardiomyopathy, hyperthyroidism, and endomyocardial fibrosis. Physicians or patients preferred OAC use despite having a CHA₂DS₂-VASc score of 0 in 24 patients (52.2%). The use of OACs did not decrease clinical events, but it increased the bleeding risk. Conclusion: Among Thai NVAF patients with CHA₂DS₂-VASc score of 0, OAC was used in 26.1%. Some stroke risk factors were identified but were not included in the current risk scoring tool.
