Introduction: A large number of patients under oral anticoagulant (OAC) or antiplatelet (AP) therapy require dental implantation. We systematically reviewed evidence on the risk of bleeding after implant placement with continued OAC or AP therapy.
Methods: PubMed, Embase and CENTRAL were searched for studies comparing bleeding outcomes after implant placement between OAC/AP therapy . controls or OAC AP therapy.
Results: Seven studies were included. Pooled analysis showed no significant difference in the risk of bleeding with continued OAC therapy control (RR 1.81 95% confidence interval [CI] 0.70, 4.63 = 14% = .22). Subgroup analysis depending on the type of OAC showed there was a non-significant tendency of increased risk of bleeding with Vitamin K antagonists (VKAs) (RR 3.42 95% CI 1.00, 11.67 = 23% = .05) but not with direct oral anticoagulants (DOACs) (RR 1.67 95% CI 0.49, 5.70 = 0% = .41). Limited data suggest an increased risk of bleeding with OAC as compared to AP (RR 0.08 95% CI 0.01, 0.76 = 0% = .03).
Conclusions: Continuation of OAC therapy in patients undergoing implant surgery does not increase the risk of bleeding provided local haemostatic measures are used. The indirect comparison suggests bleeding tendency may be higher with VKAs as compared to DOAC.

Background: Congenital factor VII (FVII) deficiency is a genetic disorder characterized by decreased FVII activity, which sometimes leads to fatal bleeding. Numerous variants have been found in FVII deficiency, but mutations vary among patients. Each mutation deserves further exploration for each patient at risk of bleeding.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral hemorrhagic fever with a high fatality rate and notable public health impact, caused by a novel phlebovirus, primarily transmitted through infected tick bites. This study aimed to assess the prevalence of co-infections among hospitalized patients with SFTS, characterize isolated pathogens, and evaluate demographics, clinical features, and laboratory variations to identify potential risk factors for co-infections. In a cohort of 78 SFTS patients categorized into co-infection and non-co-infection groups, 44.

Background: Transport by mobile stroke units (MSUs), which provide access to computed tomography scanning and intravenous blood pressure medications and thrombolytics, reduces time to treatment and may improve short-term functional outcomes for patients with acute stroke. The longer-term clinical and financial impacts remain incompletely understood. The aim of the study was to determine whether MSU care is associated with better health, utilization, and spending outcomes for patients with suspected acute stroke.

The impact of the number of stroke episodes on the natural history of patients with AF is still unclear.
Methods And Results: Using data from the international, multicenter, and prospective GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation) Registry Phase III, we categorized patients with a recent diagnosis of non-valvular AF according to the number of previous strokes (either 0, 1, or ≥2 episodes).
