Protocol for a systematic review and individual participant data meta-analysis for risk factors for lung cancer in individuals with lung nodules identified by low-dose CT screening.

BMJ Open

January 2025

Centre for Cancer Screening, Prevention and Early Diagnosis, Wolfson Institute of Population Health, Barts and The London School of Medicine and Dentistry, Queen Mary University of London, London, UK.

Background: Worldwide, lung cancer (LC) is the second most frequent cancer and the leading cause of cancer related mortality. Low-dose CT (LDCT) screening reduced LC mortality by 20-24% in randomised trials of high-risk populations. A significant proportion of those screened have nodules detected that are found to be benign.

Lung tissue from human patients and murine models of sickle cell disease pulmonary hypertension (SCD-PH) show perivascular regions with excessive iron accumulation. The iron accumulation arises from chronic hemolysis and extravasation of hemoglobin (Hb) into the lung adventitial spaces, where it is linked to nitric oxide depletion, oxidative stress, inflammation, and tissue hypoxia, which collectively drive SCD-PH. Here, we tested the hypothesis that intrapulmonary delivery of hemopexin (Hpx) to the deep lung is effective at scavenging heme-iron and attenuating the progression of SCD-PH.

January 2025

Division of Endocrinology, Department of Medicine, The Lundquist Institute at Harbor-UCLA Medical Center, Torrance, California; Clinical and Translational Science Institute, The Lundquist Institute at Harbor-UCLA Medical Center, Torrance, California.

While there are several easy-to-use reversible female contraceptives, little is available for men. Introduction of novel, cost-effective male contraceptives could have important downstream global health and economic benefits. Currently, nearly half of all pregnancies globally are unintended, with many resulting in unsafe abortions, a significant burden for women and families in many countries.

MetAssimulo 2.0: a web app for simulating realistic 1D & 2D Metabolomic 1H NMR spectra.

Bioinformatics

January 2025

Section of Bioinformatics, Division of Systems Medicine, Department of Metabolism, Digestion and Reproduction, Faculty of Medicine, Imperial College London, London, W12 0NN, United Kingdom.

Unlabelled: Metabolomics extensively utilizes Nuclear Magnetic Resonance (NMR) spectroscopy due to its excellent reproducibility and high throughput. Both one-dimensional (1D) and two-dimensional (2D) NMR spectra provide crucial information for metabolite annotation and quantification, yet present complex overlapping patterns which may require sophisticated machine learning algorithms to decipher. Unfortunately, the limited availability of labeled spectra can hamper application of machine learning, especially deep learning algorithms which require large amounts of labelled data.

The importance of fluorine and aluminum in all aspects of daily life has led to an enormous increase in human exposure to these elements in their various forms. It is therefore important to understand the routes of exposure and to investigate and understand the potential toxicity. Of particular concern are aluminum-fluoride complexes (AlF), which are able to mimic the natural isostructural phosphate group and influence the activity of numerous essential phosphoryl transferases.

Microorganisms

December 2024

Joint Institute for Food Safety and Applied Nutrition, University of Maryland, College Park, MD 20742, USA.

Accurate detection of viable O157:H7 in fresh produce wash water is critical for ensuring food safety and mitigating foodborne illnesses. This study evaluated an optimized on-filter propidium monoazide (PMA)-quantitative PCR (qPCR) method for detecting viable O157:H7 in romaine lettuce wash water, involving PMA pretreatment on a filter to block DNA amplification from dead cells. The method consistently detected viable cells across chemical oxygen demand (COD) levels of 1000 and 200 mg O/L, with no significant differences ( > 0.

Neoadjuvant (presurgical) anti-programmed cell death protein-1 (PD-1)-based immunotherapy as a new approach to cancer treatment has been developing on an accelerated trajectory since the seminal clinical trial results from studies in lung cancer and melanoma were published in 2018. Groundbreaking regulatory approvals in triple-negative breast cancer, non-small cell lung cancer and melanoma will certainly be followed by additional approvals in other disease indications, as clinical and basic research are burgeoning globally in hundreds of clinical trials across dozens of cancer types. As this field is evolving, it is addressing gaps in our understanding of biological mechanisms underlying PD-1 pathway blockade and their synergy with other antineoplastic drugs, probing mechanisms of response and resistance to neoadjuvant immunotherapy, optimizing efficacious clinical strategies, and analyzing commonalities and differences across cancer types.
