Both ganglioside GD2-targeted immunotherapy and antibody-drug conjugates (ADCs) have demonstrated clinical success as solid tumor therapies in recent years, yet no research has been carried out to develop anti-GD2 ADCs against solid tumors. This is the first study to analyze cytotoxic activity of clinically relevant anti-GD2 ADCs in a wide panel of cell lines with varying GD2 expression and their effects in mouse models of GD2-positive solid cancer.

Anti-GD2 ADCs were generated based on the GD2-specific antibody ch14.18 approved for the treatment of neuroblastoma and commonly used drugs monomethyl auristatin E (MMAE) or F (MMAF), conjugated via a cleavable linker by thiol-maleimide chemistry. The antibody was produced in a mammalian expression system, and its specific binding to GD2 was analyzed. Antigen-binding properties and biodistribution of the ADCs in mice were studied in comparison with the parent antibody. Cytotoxic effects of the ADCs were evaluated in a wide panel of GD2-positive and GD2-negativ the control group. Antitumor effects of the anti-GD2 ADCs were also confirmed in the EL-4 lymphoma model.

These findings validate the potential of ADCs targeting ganglioside GD2 in treating multiple GD2-expressing solid tumors.

Neuroendocrine tumors (NETs) overexpress somatostatin receptors (SSTRs).

We developed a second-generation, ligand-based, anti-SSTR chimeric antigen receptor (CAR) incorporating the somatostatin analog octreotide in its extracellular moiety.

Anti-SSTR CAR T cells exerted antitumor activity against SSTR+NET cell linesin vitro. The killing activity was highly specific, as demonstrated by the lack of CAR T cell reactivity against NET cells engineered to express mutated variants of SSTR2/5 by CRISPR/Cas9. When adoptively transferred in NSG mice, anti-SSTR CAR T cells induced significant antitumor activity against human NET xenografts. Although anti-SSTR CAR T cells could recognize the murine SSTRs as shown by their killing ability against murine NET cells, no obvious deleterious effects on SSTR-expressing organs such as the brain or the pancreas were observed in mice.

Taken together, our results establish anti-SSTR CAR T cells as a potential candidate for early phase clinical investigations in patients with NETs. More broadly, the demonstration that a known peptide drug can direct CAR T cell targeting may streamline the potential utility of multiple peptide motifs and provide a blueprint for therapeutic applications in a variety of cancers.

Toll-like receptors (TLRs) are critical innate immune sensors that elicit antitumor immune responses in cancer immunotherapy. Although a few TLR agonists have been approved for the treatment of patients with early-stage superficial cancers, their therapeutic efficacy is limited in patient with advanced invasive cancers. Here, we identified the therapeutic role of a TLR2/3 agonist, L-pampo (LP), which promotes antitumor immunity and enhances the immune checkpoint blockade.

We generated LP by combining a TLR2 agonist, Pam3CSK4, with a TLR3 agonist, Poly (IC). Immune responses to stimulation with various TLR agonists were compared. Tumor-bearing mice were intratumorally treated with LP, and their tumor sizes were measured. The antitumor effects of LP treatment were determined using flow cytometry, multiplexed imaging, and NanoString nCounter immune profiling. The immunotherapeutic potential of LP in combination with α-programmed cell death protein-1 (PD-1) or α-cytotoxic T-lymphocytes-associated protein 4 (Clon cancer and melanoma.

Our study demonstrated that intratumoral LP treatment improves the innate and adaptive antitumor immunity within the TME and enhances the efficacy of αPD-1 and αCTLA-4 immune checkpoint blockade.

Immune checkpoint blockade (ICB) has achieved unprecedented success in treating multiple cancer types. NGI1 However, clinical benefit remains modest for most patients with solid malignancies due to primary or acquired resistance. Tumor-intrinsic loss of major histocompatibility complex class I (MHC-I) and aberrations in antigen processing machinery (APM) and interferon gamma (IFN-γ) pathways have been shown to play an important role in ICB resistance. While a plethora of combination treatments are being investigated to overcome ICB resistance, there are few identified preclinical models of solid tumors harboring these deficiencies to explore therapeutic interventions that can bypass ICB resistance. Here, we investigated the combination of the epigenetic modulator entinostat and the tumor-targeted immunocytokine NHS-IL12 in three different murine tumor models resistant to αPD-1/αPD-L1 (anti-programmed cell death protein 1/anti-programmed death ligand 1) and harboring MHC-I, APM, and IFN-γ response deficiencies an-γ signaling.
Early detection is critical for easing the rising burden of psychiatric disorders. However, the specificity of psychopathological measurements and genetic predictors is unclear among youth.

We measured associations between genetic risk for psychopathology (polygenic risk scores (PRS) and family history (FH) measures) and a wide range of behavioral measures in a large sample (n = 5,204) of early adolescent participants (9-11 years) from the Adolescent Brain and Cognitive Development Study
. Associations were measured both with and without accounting for shared variance across measures of genetic risk.

When controlling for genetic risk for other psychiatric disorders, polygenic risk for problematic opioid use (POU) is uniquely associated with lower behavioral inhibition. Attention deficit hyperactivity disorder (ADHD), depression (DEP), and attempted suicide (SUIC) PRS shared many significant associations with externalizing, internalizing, and psychosis-related behaviors. However, when accounting for alychopathology in development.
There is a paucity of data on the burden of the full spectrum of community-acquired pneumonia (CAP) and acute otitis media (AOM) from outpatient and inpatient settings across the age spectrum.

We conducted a population-based retrospective study in Ontario and British Columbia (BC), Canada, to estimate the incidence rate of CAP and AOM in children and adults over a 14-year period using health administrative databases. CAP and AOM cases were identified from outpatient physician consultation and hospitalisation data in both provinces, and from emergency department visit data in Ontario.

During 2005-2018, Ontario had 3 607 124 CAP, 172 290 bacterial CAP, 7814 pneumococcal pneumonia, and 8 026 971 AOM cases. The incidence rate of CAP declined from 3077/100 000 in 2005 to 2604/100 000 in 2010 before increasing to 2843/100 000 in 2018; bacterial CAP incidence rate also declined from 178/100 000 in 2005 to 112/100 000 in 2010 before increasing to 149/100 000 in 2018. The incidence rate of AOM decreased from 419cination and polysaccharide vaccination of older adults have not substantially decreased the burden of pneumococcal pneumonia in older adults.
There is a substantial burden of CAP and AOM in Ontario and BC. Indirect benefits from childhood PCV vaccination and polysaccharide vaccination of older adults have not substantially decreased the burden of pneumococcal pneumonia in older adults.
The quality of health services is determined on the basis of meeting customers' needs and expectations. Due to the COVID-19 pandemic, health systems have faced high degrees of uncertainty as well as a variety of challenges. Thus, this study aimed to investigate the relationship between patient safety friendly hospital standards and customer orientation among Iranian nurses during the COVID-19 pandemic.

This cross-sectional, descriptive-analytical study was conducted on 266 nurses working in Imam Khomeini Hospital, Tehran, Iran selected via stratified sampling in 2020. The study data were collected using a questionnaire including demographic information, patient safety friendly hospital initiatives, and Kim's customer orientation scale. Then, the data were entered into the SPSS V.16 software and were analysed using descriptive statistics, dispersion indices and correlation tests.

The mean age and mean duration of working as a nurse were 38.60+7.94 and 13.87+7.41 years, respectively. From the nurses' persn among nurses.
From the nurses' viewpoint, the patient safety friendly hospital standards and customer orientation were both at the moderate level during the COVID-19 pandemic. In addition, patient safety friendly hospital standards and all its dimensions were significantly associated with customer orientation. In other words, increase in the patient safety friendly hospital standards was accompanied by an increase in the nurses' customer orientation. These results can provide the organisations delivering health services with the opportunity for management on the basis of multicriteria decision making so as to adapt with the patient safety friendly hospital standards and to internalise customer orientation among nurses.
Delirium is a serious medical condition that is common in older adults in acute settings. Clinical practice guidelines recommend that all older patients in acute care settings should be screened for delirium using standardised outcome measures.

In our institution, an audit showed that only 16% of older adults presenting to the emergency department were screened for delirium. The goal of this project was to increase the number of patients being screened for delirium using Lean Six Sigma (LSS) methodology and tools and a multidisciplinary approach.

A multidisciplinary team in the emergency department used LSS tools and methodology over a 12-week period to first identify why patients were not being screened for delirium using root cause analysis and second to implement a multifaceted intervention including education, audits and feedback, documentation changes and team huddles. An audit was performed at the 11th week of the project to measure how many patients were being screened for delirium post project intervention.

Results at 5 weeks post intervention (11th week of project) showed that the percentage of patients being screened for delirium had increased from 16% to 82%. A follow-up audit at 17 weeks post intervention showed a further improvement in delirium screening to 92%.

Applying LSS tools and methodology resulted in a healthcare quality improvement. Delirium screening in an emergency department can be improved through multifaceted interventions including education, documentation changes and team huddle changes.
