AI Article Synopsis
- The study examines the incidence of fever after transcatheter aortic valve implantation (TAVI), highlighting its commonality due to inflammatory response, with significant outcomes.
- A cohort of 802 patients from 2008-2018 was analyzed, revealing that 23.7% developed fever post-procedure, with only 32.1% linked to infections.
- The incidence of fever decreased significantly over the years and was more common in patients with first-generation devices, vascular complications, and reduced kidney function.
Article Abstract
Objectives: Fever following transcatheter aortic valve implantation (TAVI) is a common phenomenon, attributed mostly to inflammatory response which may impact outcome. Systemic inflammatory response may be triggered by multiple factors, most associated with the TAVI procedure itself. However, there are no data regarding the incidence of fever following TAVI in contemporary era with newer generation devices. Our primary objective was to measure temporal trends in fever incidence and features following TAVI.
Methods: We analyzed a retrospective cohort of 802 consecutive patients who underwent TAVI at our institution between November 2008 and February 2018. We identified and characterized all patients who developed fever (>38.0°C from any cause) within the first 72 h following the procedure and analyzed incidence and characteristics stratified into 3 time frames: 2008-2014, 2014-2016, and 2016-2018.
Results: Following TAVI, 190 (23.7%) patients developed fever (mean age 82.3 ± 5.2 years, 64.2% female). An infectious etiology was evident in only 32.1% of cases. The frequency decreased gradually and significantly across timeframes (32.8, 23.6, and 14.5%, respectively, p < 0.001). In a multivariate regression analysis, 1st generation CoreValve (HR 1.91; CI 95% 1.2-3.04, p = 0.006) was found to be associated with higher incidence of fever in addition to female gender, vascular complications, transfemoral access, and reduced GFR.
Conclusions: Fever incidence post TAVI decreased significantly throughout the last decade. The higher rate of fever in the early years of TAVI was likely associated with first-generation devices, vascular complications, and reduced GFR.

Background: Platelet recovery was an important prognostic indicator in severe fever with thrombocytopenia syndrome (SFTS). This study focused on risk factors affecting platelet recovery in surviving SFTS patients, which can assist clinicians in the early screening of patients associated with a greater risk of mortality.
Method: We retrospectively analyzed the clinical data of SFTS patients admitted to Yantai Qishan Hospital throughout 2023.

Introduction: Visceral leishmaniasis (VL) also known as Kala-azar is one of the neglected tropical diseases (NTD) of public health importance. Despite being a disease of a long history, the condition remains poorly studied especially in East Africa. For instance, whereas, the geographical location of the disease is known, there is a stark paucity of data on the burden, risk factors and clinical outcomes of this contribution in Northeastern Uganda.

We describe a rare case of serositis complicating permanent pacemaker implantation presenting 4 weeks postinsertion. A high index of suspicion for this potentially fatal complication is warranted to enable prompt diagnosis and treatment. Serositis should be considered in the differential diagnosis of a patient presenting with chest pain, fever or fatigue following recent permanent pacemaker implantation, particularly if there are elevated inflammatory markers.

Previous work identified a sub-group of trauma patients at risk for bacteremia who presented with signs of infection, including fever. A majority were older adult falls who had early onset bacteremia. Fever in the trauma bay is associated with a greater risk of adverse outcomes and identifies patients who might benefit from early initiation of interventions for sepsis.

Introduction: Temporomandibular joint (TMJ) septic arthritis is a rare frequently misdiagnosed condition with non-specific symptoms. We present our experience of thirteen cases of TMJ septic arthritis and perform a systematic review of the literature to collate the multiple characteristics of this condition.
Material And Method: A total of 133 cases of TMJ septic arthritis in humans across 62 studies were analyzed by searching PubMed, Cochrane Library, DOAJ and ClinicalTrials.
