Effects of hypoxia and iron on ascorbic acid-mediated cytotoxicity in prostate cancer cell lines.

Ascorbic acid (ASC) has long been proposed as a potential cancer co-treatment due to its specific toxicity towards cancer cells, but discrepancies between in vitro and in vivo studies suggest that external factors may modulate its cytotoxicity. Here, we investigate the impact of hypoxia and iron on the therapeutic effectiveness of ASC on prostate cancer cell lines. Hypoxia-induced increases in the EC of ASC in the prostate cancer cell lines PC-3, DU 145, LNCaP, and CWR22Rv1 but not in the prostate non-cancer cell lines RWPE-1 and TERT-PrECs.

Key considerations for a prostate cancer mRNA vaccine.

Prostate cancer has the second highest cancer mortality rate in the UK in males. Early prostate cancer is typically asymptomatic, with diagnosis at a locally advanced or metastatic stage. In addition, the inherent heterogeneity of prostate cancer tumours differs significantly in terms of genetic, molecular, and histological features.

For Atrial Fibrillation, DOACs Outperform Warfarin in Patients with Reduced Kidney Function.

At standard doses, direct oral anticoagulants (DOACs) were associated with a reduced risk of systemic embolism and intracranial hemorrhage (ICH) when compared with warfarin, with a greater derived benefit at lower creatinine clearance (CrCl-down to 25 mL/min). Lower doses of DOACs were associated with increased overall mortality without a significant decrease in ICH and incident bleeding when compared with standard dose DOACs and warfarin, across all CrCl down to 25 mL/min..

Assisted Reproductive Technology, Pregnancy, and Recurrent Disease in Melanoma Patients: A 30-Year Single Institution Experience.

Objectives: The primary aim of this study was to assess differences in melanoma recurrence between patients conceiving spontaneously versus those undergoing assisted reproductive technology (ART) and to determine use of ART in post-melanoma patients. A secondary aim was to describe the use of immunotherapy as a novel treatment regimen for metastatic melanoma in a cohort of fertile patients.

Design: This study is a 30-year analysis including data from a single-center questionnaire and a retrospective cohort study.

Perspectives on Drug Product Design Among Patients with Lung Cancer in the United Kingdom.

Introduction: The use of oral anticancer medications has become more prevalent in cancer therapy. This is particularly the case in the management of advanced non-small cell lung cancer (NSCLC). However, when the treatment delivery interaction between the patient and the healthcare provider is removed, the risk of non-adherence increases.

A Discrete-Choice Experiment Assessing the Patient Preferences and Real-World Experiences of Patients with Migraine in Japan.

Introduction: Migraine is a debilitating headache disorder with a high prevalence in Japan that imposes significant societal burden. Although the Japanese Clinical Practice Guideline for Headache Disorders 2021 recommends both acute and preventive migraine treatments, the usage of preventive treatments is still limited. Therefore, it is crucial to understand the treatment preferences of patients with migraine pertaining to both acute and preventive treatments.

Evaluating the efficacy of Rose Bengal-PVA combinations within PCL/PLA implants for sustained cancer treatment.

The current investigation aims to address the limitations of conventional cancer therapy by developing an advanced, long-term drug delivery system using biocompatible Rose Bengal (RB)-loaded polyvinyl alcohol (PVA) matrices incorporated into 3D printed polycaprolactone (PCL) and polylactic acid (PLA) implants. The anticancer drug RB's high solubility and low lipophilicity require frequent and painful administration to the tumour site, limiting its clinical application. In this study, RB was encapsulated in a PVA (RB@PVA) matrix to overcome these challenges and achieve a localised and sustained drug release system within a biodegradable implant designed to be implanted near the tumour site.

3D-printed implants loaded with acriflavine for glioblastoma treatment.

Drug delivery routes play an essential role in determining the efficacy and safety of medications. This study focused on the development and optimization of 3D-printed reservoir type implants as a combinational therapy drug delivery system for Glioblastoma Multiforme (GBM) post-surgery, possessing also antibacterial properties. In this study, we used a multimodal agent, Acriflavine (ACF) as an alternative drug to treat GBM.

Proof-of-concept study: Remote capillary blood collection for hCG analysis in early pregnancy.

Introduction: Capillary blood collection, a technique traditionally used in diabetes care, shows promise for many applications including pregnancy monitoring. Serial measurement of serum human Chorionic Gonadotrophin (hCG) is frequently necessary for managing early pregnancy, including molar pregnancy, requiring multiple visits to a maternity hospital for blood collection by venepuncture. This proof-of-concept study aimed to assess the clinical performance and user acceptability of capillary blood samples collected remotely, as an alternative to venous blood for hCG measurement.

Immunotherapy for HPV negative head and neck squamous cell carcinoma.

Head and neck cancer (HNSCC) is the 8th most common cancer in the UK, with incidence increasing due to lifestyle factors such as tobacco and alcohol abuse. HNSCC is an immune-suppressive disease characterised by impaired cytokine secretion and dysregulation of immune infiltrate. As such, immunotherapy is a potential treatment option, with therapeutic cancer vaccination demonstrating the greatest potential.

Supporting health and wellbeing in health care employees: a documentary review of organizational policies, strategies and frameworks.

Background: Health care workers are crucial for a productive and thriving health care system, yet the health and lifestyle behaviour of key groups within this workforce (for example nurses and healthcare assistants/support workers) is typically poor. The extent of health and wellbeing documents that guide action towards improving their health and wellbeing is unknown. Using one health care system, NHS Scotland, as an example, the aim of this study was to assess the number of NHS health boards with workplace documents focused on health and wellbeing of employees, the quality of these documents and the extent to which they reference lifestyle behaviours, namely physical activity.

A latent class analysis of factors influencing preferences for infant respiratory syncytial virus (RSV) preventives among pregnant people in the United States.

A maternal vaccine and long-acting monoclonal antibody (mAb) were recently approved to protect infants against respiratory syncytial virus (RSV). We identified subgroups of pregnant people with different preferences for RSV preventives and respondent characteristics associated with subgroup membership. An online survey, including a discrete choice experiment (DCE), was conducted among US pregnant people.

Neoblast-like stem cells of Fasciola hepatica.

The common liver fluke (Fasciola hepatica) causes the disease fasciolosis, which results in considerable losses within the global agri-food industry. There is a shortfall in the drugs that are effective against both the adult and juvenile life stages within the mammalian host, such that new drug targets are needed. Over the last decade the stem cells of parasitic flatworms have emerged as reservoirs of putative novel targets due to their role in development and homeostasis, including at host-parasite interfaces.

Falls in Older Adults: Approach and Prevention.

Falls are a major public health problem, occurring in more than 27% of adults 65 years and older and costing the U.S. health care system tens of billions of dollars each year.

Healthcare Providers' and Pregnant People's Preferences for a Preventive to Protect Infants from Serious Illness Due to Respiratory Syncytial Virus.

We assessed the impact of respiratory syncytial virus (RSV) preventive characteristics on the intentions of pregnant people and healthcare providers (HCPs) to protect infants with a maternal vaccine or monoclonal antibodies (mAbs). Pregnant people and HCPs who treated pregnant people and/or infants were recruited via convenience sample from a general research panel to complete a cross-sectional, web-based survey, including a discrete choice experiment (DCE) wherein respondents chose between hypothetical RSV preventive profiles varying on five attributes (effectiveness, preventive type [maternal vaccine vs. mAb], injection recipient/timing, type of medical visit required to receive the injection, and duration of protection during RSV season) and a no-preventive option.

The value of knowing: preferences for genetic testing to diagnose rare muscle diseases.

Background: Genetic testing can offer early diagnosis and subsequent treatment of rare neuromuscular diseases. Options for these tests could be improved by understanding the preferences of patients for the features of different genetic tests, especially features that increase information available to patients.

Methods: We developed an online discrete-choice experiment using key attributes of currently available tests for Pompe disease with six test attributes: number of rare muscle diseases tested for with corresponding probability of diagnosis, treatment availability, time from testing to results, inclusion of secondary findings, necessity of a muscle biopsy, and average time until final diagnosis if the first test is negative.

Patient preferences in genetic newborn screening for rare diseases: study protocol.

Introduction: Rare diseases (RDs) collectively impact over 30 million people in Europe. Most individual conditions have a low prevalence which has resulted in a lack of research and expertise in this field, especially regarding genetic newborn screening (gNBS). There is increasing recognition of the importance of incorporating patients' needs and general public perspectives into the shared decision-making process regarding gNBS.

Morphology combined with D-DISH ploidy analysis to diagnose partial hydatidiform mole: an evaluation audit using molecular genotyping.

Aims: A hydatidiform mole (HM) is classified as complete (CHM) or partial (PHM) based on its morphology and genomic composition. Ancillary techniques are often required to confirm a morphologically suspected PHM diagnosis. This study sought to evaluate the clinical accuracy of PHM diagnosis using morphological assessment supported by dual-colour dual-hapten in situ hybridisation (D-DISH) ploidy determination.

Novel scoring system provides high separation of diploidy and triploidy to aid partial hydatidiform mole diagnosis: an adaption of D-DISH for ploidy analysis.

Aims: Diagnosis of hydatidiform mole or molar pregnancy based on morphology alone can be challenging, particularly in early gestation, necessitating the use of ancillary techniques for accurate diagnosis. We sought to adapt the VENTANA dual-colour dual-hapten in-situ hybridisation (D-DISH) assay by using the internal chromosome 17 enumeration probe to determine ploidy status.

Methods: We selected 25 products of conception, consisting of molar and non-molar cases, to validate the D-DISH assay.
