Adverse cardiovascular events and cardiac imaging findings in patients on immune checkpoint inhibitors.

Background: There is an urgent need to better understand the diverse presentations, risk factors, and outcomes of immune checkpoint inhibitor (ICI)-associated cardiovascular toxicity. There remains a lack of consensus surrounding cardiovascular screening, risk stratification, and clinical decision-making in patients receiving ICIs.

Methods: We conducted a single center retrospective cohort study including 2165 cancer patients treated with ICIs between 2013 and 2020.

A practice already in use: a snapshot survey on the use of doxycycline as a preventive strategy (Doxy-PEP and Doxy-PrEP) in the GBMSM population in Spain.

Purpose: . While doxycycline shows promise as a preventative measure against certain STIs (post-exposure prophylaxis or PEP, and pre-exposure prophylaxis or PrEP), very few medical and scientific associations favor its community use. Nevertheless, sexual health organizations for gay, bisexual and other men who have sex with men (GBMSM) community have noticed an increase in requests of its use.

Cryptococcal Meningitis in an Apparent Immunocompetent Host.

Cryptococcal meningitis is a severe fungal infection that primarily affects individuals with compromised immune systems, such as those with the human immunodeficiency virus (HIV) or those undergoing immunosuppressive therapies after organ transplantation. In rare cases, immunocompetent individuals may also be affected by this life-threatening condition. We present the case of a 64-year-old male patient with no known underlying immune deficiency diagnosed with cryptococcal meningitis, who presented with persistent headaches and subjective fevers.

Chemsex in Barcelona: A qualitative study of factors associated with the practice, the perception of the impact on health and prevention needs.

Chemsex is defined as use of psychoactive drugs with the aim of having sexual relations between gay men, bisexuals and men who have sex with men for a long period of time. To study this phenomenon, this qualitative descriptive study was proposed with the objective of describing the practice of chemsex from the perspective of users, to determine the main factors associated with its practice, the perception of the impact on their health and to establish prevention needs. Data were obtained using conversational techniques: 12 semi-structured interviews and 3 focus groups.

TAL Effector Repertoires of Strains of pv. in Commercial Cassava Crops Reveal High Diversity at the Country Scale.

Transcription activator-like effectors (TALEs) play a significant role for pathogenesis in several xanthomonad pathosystems. pv. (), the causal agent of Cassava Bacterial Blight (CBB), uses TALEs to manipulate host metabolism.

Removal of ligand-bound liposomes from cell surfaces by microbubbles exposed to ultrasound.

Gas-filled microbubbles attached to cell surfaces can interact with focused ultrasound to create microstreaming of nearby fluid. We directly observed the ultrasound/microbubble interaction and documented that under certain conditions fluorescent particles that were attached to the surface of live cells could be removed. Fluorescently labeled liposomes that were larger than 500 nm in diameter were attached to the surface of endothelial cells using cRGD targeting to αvβ3 integrin.

Spinal Cord Stimulator Related Infections: Findings From a Multicenter Retrospective Analysis of 2737 Implants.

Introduction: Surgical site infection is a potential complication of spinal cord stimulator (SCS) implantation. Current understanding of the epidemiology, diagnosis, and treatment of these infections is based largely on small clinical studies, many of which are outdated. Evidence-based guidelines for management of SCS-related infections thus rely instead on expert opinion, case reports, and case series.

Characterization and optimization of mTHPP nanoparticles for photodynamic therapy of head and neck cancer.

Objectives: To characterize the properties of polymeric micelles containing different loading percentages of mTHPP, a photosensitizer for photodynamic therapy (PDT), with respect to fluorescence, singlet oxygen ((1)O(2)) yield, and in vitro cytotoxicity in head and neck cancer cells.

Study Design: Laboratory study.

Setting: Polymer chemistry laboratory.
