    Introduction: Tenecteplase (TNK) has demonstrated to be non-inferior to alteplase (ALT) for intravenous thrombolysis (IVT) in acute ischemic stroke (AIS). There are potential workflow benefits associated with TNK use, aiming to reduce patient length of stay in the emergency department. Our aim was to investigate whether the routine use of TNK during the COVID-19 pandemic influenced workflow times compared to historical use of ALT, while maintaining non-inferior clinical outcomes in a non-drip and ship scenario of a comprehensive stroke center. Methods: We included patients with AIS admitted from September 2019 to September 2022 and compared those treated with TNK during the COVID-19 pandemic to those treated with ALT in the period immediately before. We compared emergency department length of stay (EDLOS), door-to-needle time (DTN), door-to-groin puncture time (DTG), clinical and safety outcomes with adjusted general linear regression models. Results: 110 patients treated with TNK and 111 with ALT were included in this study. Mean EDLOS was 251 (SD = 164) min for TNK users versus 240 (SD = 148) min for ALT (p = 0.62). Mean DTN was 43 (SD = 25) min for TNK versus 46 (SD = 27) min for ALT users (p = 0.39). Mean DTN under 60 min was achieved in 86 (78.2%) patients and in 85 (76.5%) patients of the TNK and ALT groups, respectively (p = 1.0). DTN under 45 min was achieved in 65.4% and 58.6% (p = 0.65) of the TNK and ALT groups, respectively. DTG time was 114 (SD = 43) min for TNK versus 111 (58 = SD) min in the ALT group (p = 0.88). DTG under 90 min was achieved in 32% of the TNK group and 35% of the ALT group (p = 0.69). There were no differences in any of the clinical or safety outcomes between groups at 90 days. Conclusions: The adoption of TNK during COVID-19 pandemic did not result in a change in EDLOS, DTN, or DTG times when compared to ALT in this cohort. Safety and clinical outcomes were similar between groups. Probably a greater benefit could have been seen in a drip and ship thrombolysis setting. Further research is needed to assess the potential advantages of TNK in drip and ship scenarios of IVT.

    Clinical Profile of Stroke Chameleons Receiving Intravenous Thrombolysis: Insights from a Single-Center Experience
    <jats:p>Introduction: In emergency rooms (ERs), 5% of patients experiencing an acute ischemic stroke (AIS) receive an alternative diagnosis; these cases are known as stroke chameleons (SC). The percentage of SC treated with intravenous thrombolysis (IVT) and the characteristics have not been well described. We aimed at investigating the variables associated with the probability receiving IVT. Methods: In this prospective study, we included consecutive patients with SC admitted at the ER of Clínica Alemana between September 2014 and October 2023. Results: Among 1,193 stroke patients; sixty-three (5.2%) corresponded to SC. Ten of these cases (15.8%, 95% CI: 8.8–26.8) were treated with IVT, mean door-to-needle (DTN) time of 85.7 (SD 35) min, median of 73.5 (IQR 62–113) min. SCs who underwent IVT were younger (p = 0.01), with higher NIHSS (p = 0.05). They presented more frequently with altered level of consciousness in the NIHSS (p = 0.01), language abnormities (p = 0.001), and dysarthria (p = 0.01). In multivariate analysis, none of the variables were significantly associated with IVT. A secondary analysis showed that only time to brain imaging was significantly associated with IVT (OR: 0.99; 95% CI: 0.98–0.99; p = 0.01). Conclusions: Almost 1 out of every 7 SC could be treated with IVT but with a prolonged DTN time; the chance of being treated is associated with time to brain imaging. &lt;p&gt;Introduction: In emergency rooms (ERs), 5% of patients experiencing an acute ischemic stroke (AIS) receive an alternative diagnosis; these cases are known as stroke chameleons (SC).

    Photobiomodulation therapy to prevent oral mucositis and functional impairment in adult patients with haematological cancer undergoing haematopoietic stem cell transplantation: randomised trial protocol
    <jats:sec><jats:title>Introduction</jats:title><jats:p>Oral mucositis is a highly prevalent condition in individuals treated for haematological neoplasms, primarily during haematopoietic stem cell transplantation (HSCT). The condition is known to delay recovery processes, increasing the risk of infection, the number of interventions and the length of hospital stays. The proposed Photobiomodulation Therapy for Oral Mucositis and Functional Impairment Transplantation Trial aims to assess the effectiveness and acceptability of using photobiomodulation in the oral cavity to prevent oral mucositis and functional impairment in adult patients undergoing HSCT.</jats:p></jats:sec><jats:sec><jats:title>Methods and analysis</jats:title><jats:p>This is an assessor-blinded and statistician-blinded, parallel-group randomised controlled clinical trial (photobiomodulation vs control group). Participants and setting: 30 patients, aged 18–65 years, with haematological neoplasms undergoing HSCT at the Clínica Dávila Oncology and Bone Marrow Transplant Unit. Primary outcome measures: oral mucositis will be assessed daily using the WHO grading scale, beginning on the day of transplant through day 20 post-transplant. Researchers will assess functional capacity using a 2 min step test, handgrip strength with the Jamar digital dynamometer, lower limb strength using a 30’ sit-to-stand test and quality of life with the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation Questionnaire. Acceptability will be assessed by logging treatment adherence and using a Visual Analogue Scale. Assessments will occur at two time points (1): on admission to the transplant unit, before starting the conditioning regimen and (2) on the day of discharge. Intervention: three times per week photobiomodulation therapy using a diode laser device will begin the first day of conditioning and continue through day 3 post-transplant.</jats:p></jats:sec><jats:sec><jats:title>Ethics and dissemination</jats:title><jats:p>The Clínica Dávila and Universidad del Desarrollo Clinical Research Ethics Committees approved this study in accordance with the Helsinki Declaration.

    <jats:title>Abstract</jats:title> <jats:sec> <jats:title>Background</jats:title> <jats:p>The CDC reported a 35% increase in hospital-onset (HO) carbapenem-resistant Enterobacterales (CRE) infections during the COVID-19 pandemic. We evaluated patient outcomes following HO and community-onset (CO) CRE bloodstream infections (BSI).</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>Patients prospectively enrolled in CRACKLE-2 from 56 hospitals in 10 countries between 30 April 2016 and 30 November 2019 with a CRE BSI were eligible. Infections were defined as CO or HO by CDC guidelines, and clinical characteristics and outcomes were compared. The primary outcome was desirability of outcome ranking (DOOR) 30 days after index culture. Difference in 30-day mortality was calculated with 95% CI.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>Among 891 patients with CRE BSI, 65% were HO (582/891). Compared to those with CO CRE, patients with HO CRE were younger [median 60 (Q1 42, Q3 70) years versus 65 (52, 74); P &amp;lt; 0.001], had fewer comorbidities [median Charlson comorbidity index 2 (1, 4) versus 3 (1, 5); P = 0.002] and were more acutely ill (Pitt bacteraemia score ≥4: 47% versus 32%; P &amp;lt; 0.001). The probability of a better DOOR outcome in a randomly selected patient with CO BSI compared to a patient with HO BSI was 60.6% (95% CI: 56.8%–64.3%). Mortality at 30-days was 12% higher in HO BSI (192/582; 33%) than CO BSI [66/309 (21%); P &amp;lt; 0.001].</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusion</jats:title> <jats:p>We found a disproportionately greater impact on patient outcomes with HO compared to CO CRE BSIs; thus, the recently reported increases in HO CRE infections by CDC requires rigorous surveillance and infection prevention methods to prevent added mortality.</jats:p> </jats:sec>

    <jats:p>In 2006, the human papillomavirus (HPV) vaccine was approved for use as an effective intervention for reducing the risk of developing cervical cancer; however, its successful implementation is dependent on acceptability. This study aims to provide a comprehensive understanding of the reasons that favor or do not favor the acceptability of HPV vaccines. Methods: We conducted a systematic review and meta-summary of qualitative research on 16 databases. A total of 32 articles that considered the perspectives of vaccine users, their parents, and the professionals who care for them were reviewed. Synthesis was conducted as described by Sandelowski and Barroso. Results: We used inductive and deductive methods to obtain a total of 22 dimensions, out of which three issues stood out that should be considered to improve acceptability and are formed by three groups of study, namely, information about the vaccine, fears and side effects, and sexuality associated with the vaccine. Conclusions: Acceptability, as well as adherence to HPV vaccination, is a complex concept. This review highlights the perspectives of the three sets of actors involved in the process (i.e., users, parents, and professionals) and views these factors in relation to acceptability as a guide for new interventions.</jats:p>
