Humor in healthcare

Cancer patients are at risk for severe coronavirus disease 2019 (COVID-19) outcomes due to impaired immune responses. However, the immunogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is inadequately characterized in this population. We hypothesized that cancer vs non-cancer individuals would mount less robust humoral and/or cellular vaccine-induced immune SARS-CoV-2 responses. Receptor binding domain (RBD) and SARS-CoV-2 spike protein antibody levels and T-cell responses were assessed in immunocompetent individuals with no underlying disorders ( n = 479) and immunocompromised individuals ( n = 115)...

The convergence strategies of antigenic subunits and synthetic nanoparticle scaffold platform improve the vaccine production efficiency and enhance vaccine-induced immunogenicity. The selection of the appropriate nanoparticle scaffold is critical for the immunological control of the target antigens. Lumazine synthase (LS) is an attractive candidate for a vaccine display system due to its thermo-stability, modification tolerance, and morphological plasticity. Here, the first development of a multivalent thermostable scaffold, LS-SUMO, and a divalent nanovaccine covalently conjugated with CHIKV E2 and ZIKV EDIII antigens, was reported...

PURPOSE: Anti SARS-CoV-2 vaccination initially showed high effectiveness in preventing COVID-19. However, after the surge of variants of concern, the effectiveness dropped. Several studies investigated if this was related to the decrease of the humoral response over time; however, this issue is still unclear. The aim of this study was to understand whether SARS-CoV-2 anti-S IgG levels can be used to predict breakthrough infection risk and define the timing for further booster doses administration...

Cerebrospinal fluid (CSF) metagenomic next generation sequencing (mNGS) can detect diverse pathogens in patients with central nervous system infection. Due to its high cost and unclear clinical utility, it is typically reserved for patients with unrevealing routine workups. A multi-center retrospective analysis of real-world CSF mNGS was performed involving orders between 2017 and 2022 at a large New England healthcare system. CSF mNGS was performed 64 times with 17 positive results (27 %). In 11/17 positive samples (65 %), the infectious agent had not been previously detected using routine methods...

The effectiveness of COVID-19 vaccines developed against the original virus strain deteriorated noticeably in efficacy against the Omicron variant (B.1.1.529). Moreover, the immunity developed after vaccination or due to natural infection rapidly waned. In the present study, covering this period, we summarize the incidence of breakthrough infections among healthcare workers (HCWs) with respect to administration of the three vaccine doses. Additionally, we evaluate the long-term SARS-CoV-2-specific humoral and T cell responses at two different time points: six and twelve months after receipt of the third (booster) dose...

This narrative review critically examines the current research on the health implications of whey protein (WP) supplementation, with a focus on potential risks and adverse effects. WP, commonly consumed for muscle building and weight loss, has been associated with various health concerns. Our comprehensive analysis involved a thorough search of multiple databases, resulting in the inclusion of 21 preclinical and human studies that collectively offer a detailed overview of WP's health impacts. The review reveals significant findings, such as WP's potential link to liver and kidney damage, alterations in gut microbiota, increased acne incidence, impacts on bone mass, and emotional and behavioural changes...

Several countries have recommended a booster dose of Pfizer BNT162b2 vaccine for subjects under the age of 60, who have already received the first dose of ChAdOx1. This is due to several ChAdOx1 vaccine-associated adverse vascular events and thrombocytopenia. Neutralization assay and quantitative IgG anti-SARS-CoV-2 Spike antibody (anti-S-IgG) were conducted to investigate the long-term responses to vaccine treatment in a cohort of Sardinian participants, who have received heterologous Prime-Boost Vaccination via ChAdOx1 vector vaccine and a booster dose via BNT162b2...

Coxiella burnetti is an intracellular bacterium that causes Q fever, a disease of worldwide importance. Q-VAX® , the approved human Q fever vaccine, is a whole cell vaccine associated with safety concerns. Here we developed a safe particulate subunit vaccine candidate that is ambient-temperature stable and can be cost-effectively manufactured. We bioengineered endotoxin-free Escherichia coli to efficiently self-assemble biopolymer particles (BPs) that are densely coated with either strings of 18 T-cell epitopes (COX-BP) or two full-length immunodominant antigens (YbgF-BP-Com1) all derived from C...

Studies about the duration of the humoral and cellular response following the bivalent booster administration are still scarce. We aimed at assessing the humoral and cellular response in a cohort of healthcare workers that received this booster. Blood samples were collected before the administration of the bivalent booster from Pfizer-BioNTech and after 14, 28, 90, and 180 days. Neutralizing antibodies against either the D614G strain, the delta variant, the BA.5 variant, or the XBB.1.5 subvariant were measured...

Self-assembling protein nanoparticles are a promising class of materials for targeted drug delivery. Here we report the use of a computationally designed, two-component icosahedral protein nanoparticle to encapsulate multiple macromolecular cargoes via simple and controlled self-assembly in vitro. Single-stranded RNA molecules between 200 and 2500 nucleotides in length were encapsulated and protected from enzymatic degradation for up to a month with length-dependent decay rates. Immunogenicity studies of nanoparticles packaging synthetic polymers carrying a small-molecule TLR7/8 agonist showed that co-delivery of antigen and adjuvant resulted in a more than 20-fold increase in humoral immune responses while minimizing systemic cytokine secretion associated with free adjuvant...

BACKGROUND: Despite growing evidence of the potential of arts-based modalities to translate knowledge and spark discussion on complex issues, applications to health policy are rare. This study explored the potential of a research-based theatrical video to increase public capacity and motivation to engage with the complex issues that make Emergency Department wait times such an intractable problem. METHODS: Larry Saves the Canadian Healthcare System is a digital musical micro-series developed from extensive research examining system-level causes of Emergency crowding and the ineffectiveness of prevailing approaches...

RATIONALE: Magic, traditionally perceived as entertainment, has been increasingly employed in healthcare to enhance health and well-being. Despite its potential benefits across various dimensions of health, including biological, psychological, and social, a comprehensive review highlighting its broad applications in healthcare remains unexplored. OBJECTIVE: This study aims to explore the diverse uses of magic within healthcare, progressing from entertainment to integral medical care, termed "magicine...

OBJECTIVES: Although antibody measurements using lateral flow assay (LFA) kits are convenient, they usually require a specialized reader for quantification. However, a smartphone-based quantification application can be used as a reader for LFA kits. We investigated the quantification ability of the application for SARS-CoV-2-specific antibodies. METHODS: Eight hundred frozen serum samples from 100 healthcare professionals who received a COVID-19 vaccine were analyzed...

Liver transplantation is a critical procedure for patients with end-stage liver disease, but it is often hindered by ABO-incompatibility between the donor and recipient, which can lead to immediate humoral rejection. We present a unique case involving a 10-month-old patient who, by accident, received an ABO-incompatible partial liver transplant from a type A mother without undergoing desensitization. Remarkably, during a 21-year follow-up period, the patient exhibited no signs of humoral or graft rejection, despite nonadherence to medication...

Introduction: The impact of long-COVID-19 syndrome is rather variable, since it is influenced by several residual confounders. This study aimed to investigate the prevalence of long COVID-19 in healthcare workers (HCWs) from four university hospitals in north-eastern Italy: Trieste, Padua, Verona, and Modena-Reggio Emilia. Methods: During the period June 2022-August 2022, HCWs were surveyed for past COVID-19 infections, medical history, and any acute as well as post-COVID-19 symptoms. The prevalence of long COVID-19 was estimated at 30-60 days or 61+ days since first negative swab following first and second COVID-19 episode...

There is still a long way ahead regarding the COVID-19 pandemic, since emerging waves remain a daunting challenge to the healthcare system. For this reason, the development of new preventive tools and therapeutic strategies to deal with the disease have been necessary, among which serological assays have played a key role in the control of COVID-19 outbreaks and vaccine development. Here, we have developed and evaluated an immunoassay capable of simultaneously detecting multiple IgG antibodies against different SARS-CoV-2 antigens through the use of Bio-PlexTM technology...

Immunogenic biologics trigger an anti-drug antibody (ADA) response in patients that reduces efficacy and increases adverse reactions. Our laboratory has shown that targeting protein antigen to the liver microenvironment can reduce antigen-specific T cell responses; herein, we present a strategy to increase delivery of otherwise immunogenic biologics to the liver via conjugation to a synthetic mannose polymer, p(Man). This delivery leads to reduced antigen-specific T follicular helper cell and B cell responses resulting in diminished ADA production, which is maintained throughout subsequent administrations of the native biologic...

OBJECTIVES: To assess the immunity of healthcare and non-healthcare workers in the Alcoy health area (Spain) after completing three doses of the Pfizer-BioNTech vaccine and how it relates with individual factors. METHODS: We conducted a prospective, observational, longitudinal, analytical study to observe immunogenicity in healthcare and non-healthcare workers at Virgen de los Lirios Hospital following administration of three doses of the Pfizer-BioNTech vaccine...

OBJECTIVE: The effect of stress on vaccine-induced humoral immunity and therapeutic interventions to mitigate pandemic-related stress remain under-explored. METHODS: Participants in a longitudinal cohort study (n = 189) completed a validated measure, 7-instrument Generalized Anxiety Disorder (GAD-7), and 10-instrument stress measure (SM-10) to assess stress and anxiety following SARS-CoV-2 vaccination. Serum was collected to obtain SARS-CoV-2 antibody titer levels...

INTRODUCTION: Throughout the SARS-CoV-2 pandemic, Germany like other countries lacked adaptive population-based panels to monitor the spread of epidemic diseases. METHODS: To fill a gap of population-based estimates needed for winter 2022/23 we resampled in the German SARS-CoV-2 cohort study MuSPAD in mid-2022, including characterization of systemic cellular and humoral immune responses by interferon-γ-release assay (IGRA) and CLIA/IVN assay. We were able to confirm categorization of our study population into four groups with differing protection levels against severe COVID-19 course based on literature synthesis...
