Background: Immunotherapy has demonstrated limited activity in prostate cancer to date. This likely reflects an immune suppressive tumor microenvironment (TME), with previous studies suggesting low PD-L1 expression and a sparse immune cell infiltrate. We aimed to further characterise the immune TME in primary prostate cancer and correlate immune subset densities with clinical outcomes.

Article Synopsis
  • Intestinal dysbiosis in preterm babies is linked to conditions like necrotising enterocolitis and late-onset sepsis, and non-invasive positive pressure ventilation may negatively influence gut bacterial growth.
  • A study using high-throughput 16S rRNA gene sequencing found that transitioning from respiratory support to spontaneous breathing in preterm infants led to increased bacterial diversity and changes in specific gut bacteria.
  • The findings suggest that non-invasive positive pressure ventilation may suppress gut microbiome diversity and anaerobic bacteria, highlighting the need for strategies to promote a healthy gut microbiome in preterm infants.

Protein A (PA) is a bacterial cell wall component of Staphylococcus aureus whose function is to bind to Immunoglobulin G (IgG). Given its ability to bind IgG as well as its stability and resistance to harsh acidic and basic cleaning conditions, it is commonly used in the affinity chromotography purification of biotherapeutics. This use can result in levels of PA being present in a drug product and subsequent patient exposure.

Human coronavirus 229E (HCoV-229E) is associated with upper respiratory tract infections and generally causes mild respiratory symptoms. HCoV-229E infection can cause cell death, but the molecular pathways that lead to virus-induced cell death as well as the interplay between viral proteins and cellular cell death effectors remain poorly characterized for HCoV-229E. Studying how HCoV-229E and other common cold coronaviruses interact with and affect cell death pathways may help to understand its pathogenesis and compare it to that of highly pathogenic coronaviruses.

In order to become bioactive, proteins must be translated and protected from aggregation during biosynthesis. The ribosome and molecular chaperones play a key role in this process. Ribosome-bound nascent chains (RNCs) of intrinsically disordered proteins and RNCs bearing a signal/arrest sequence are known to interact with ribosomal proteins.

Multiple international guidelines exist that describe both quality and safety considerations for the control of the broad spectrum of impurities inherent to drug substance and product manufacturing processes. However, regarding non-mutagenic impurities (NMI) the most relevant ICH Q3A/B guidelines are not applicable during early phases of drug development leading to confusion about acceptable limits at this stage. Thus, there is need for more flexible approaches that ensure that patient safety remains paramount, while taking into consideration the limited duration of exposure.

Interactions between ribosome-bound nascent chains (RNCs) and ribosomal components are critical to elucidate the mechanism of cotranslational protein folding. Nascent protein-ribosome contacts within the ribosomal exit tunnel were previously assessed mostly in the presence of C-terminal stalling sequences, yet little is known about contacts taking place in the absence of these strongly interacting motifs. Further, there is nearly no information about ribosomal proteins (r-proteins) interacting with nascent chains within the outer surface of the ribosome.

Relational autonomy is a concept that describes the interdependent nature of decision making by individuals. Relational autonomy is distinct from the traditional concept of autonomy, which asserts the need for each individual to make choices based on their own values and without influence by others. We present a case in which a patient made decisions that appeared contrary to his own desires.

The International Union of Pure and Applied Chemistry (IUPAC) has a long tradition of supporting the compilation of chemical data and their evaluation through direct projects, nomenclature and terminology work, and partnerships with international scientific bodies, government agencies and other organizations. The IUPAC Interdivisional Subcommittee on Critical Evaluation of Data (ISCED) has been established to provide guidance on issues related to the evaluation of chemical data. In this first report we define the general principles of the evaluation of scientific data and describe best practices and approaches to data evaluation in chemistry.

Background: People who inject drugs (PWID) are at risk for severe bacterial and fungal infections including skin and soft tissue infections, endocarditis, and osteomyelitis. PWID have high rates of self-directed discharge and are often not offered outpatient antimicrobial therapies, despite studies showing their efficacy and safety in PWID. This study fills a gap in knowledge of patient and community partner perspectives on treatment and discharge decision making for injection drug use (IDU)-associated infections.

Low levels of N-nitrosamines (NAs) were detected in pharmaceuticals and, as a result, health authorities (HAs) have published acceptable intakes (AIs) in pharmaceuticals to limit potential carcinogenic risk. The rationales behind the AIs have not been provided to understand the process for selecting a TD or read-across analog. In this manuscript we evaluated the toxicity data for eleven common NAs in a comprehensive and transparent process consistent with ICH M7.

Article Synopsis
  • Proteins released from the ribosome are prone to aggregating, making chaperones like Hsp70 and trigger factor (TF) crucial for maintaining their solubility and structure early in their life.
  • Research showed that while Hsp70 can help with the solubility of newly synthesized proteins, its effectiveness is highly dependent on the specific protein sequence and may not prevent all types of aggregates.
  • The findings reveal limitations in Hsp70's ability to protect against protein aggregation, particularly for proteins that are highly prone to forming aggregates, indicating a need for improved strategies to manage these issues post-ribosome release.

Article Synopsis
  • Routine screening for DNA mismatch repair (MMR) deficiency in certain tumors often results in unresolved cases labeled as suspected Lynch syndrome (SLS), with a study involving 135 such cases across Australia and New Zealand.
  • Targeted sequencing of tumors and matched blood samples revealed that 86.9% of these SLS cases could be classified into specific subtypes, primarily through the detection of double somatic MMR mutations.
  • The research indicates that implementing tumor-focused testing and MLH1 methylation assays in clinical settings can effectively clarify SLS diagnoses, leading to better surveillance and screening for patients.

Objectives: Some patients with sickle cell disease (SCD) have features of nociplastic pain. While research suggests that many patients with nociplastic pain consume more opioids due to opioid nonresponsiveness, little is known about the impact of nociplastic pain and pain catastrophizing on opioid consumption and pain interference among adolescents and young adults (AYA) with SCD. The purpose of this study was to (1) characterize nociplastic pain and pain catastrophizing among AYA with SCD, and (2) determine whether these characterizations are associated with subsequent opioid consumption and pain interference 1 month after characterization.

Background: The prevalence of injection drug use (IDU)-associated infections and associated hospitalizations has been increasing for nearly two decades. Due to issues ranging from ongoing substance use to peripherally inserted central catheter safety, many clinicians find discharge decision-making challenging. Typically, clinicians advise patients to remain hospitalized for several weeks for intravenous antimicrobial treatment; however, some patients may desire other antimicrobial treatment options.

Purpose: The goal of this study was to compare the efficacy of intraarterial chemotherapy (IAC) for retinoblastoma delivered via the ophthalmic artery (OA) division of the internal carotid artery (ICA) versus alternative branches of the external carotid artery (ECA).

Methods: We performed a retrospective chart review of patients receiving IAC for retinoblastoma at a single institution. Subjects were divided into three groups: those that received IAC solely through the OA branch of the ICA, those that initially received IAC through the OA branch of the ICA but were later switched to the ECA, and those that only received IAC through the ECA.
