Introduction: Epidermal growth factor receptor (EGFR) mutations are key oncogenic drivers in lung adenocarcinoma (LUAD), predominantly affecting Asian, non-smoking, and female populations. While common mutations, such as exon 19 deletions and L858R, respond well to tyrosine kinase inhibitors (TKIs), uncommon EGFR mutations and compound variants exhibit variable treatment responses. This study aims to compare clinical characteristics and molecular profiles of patients with common, uncommon, and compound EGFR mutations, assessing their implications for therapy outcomes.

Hemato-oncologic children form a heterogeneous group with a wide spectrum of ages, malignancy types, and immunosuppression grades during the different phases of their treatment. Immunosuppression is caused by multiple factors, including the malignancy itself, bone marrow suppression secondary to therapy, and wide use of steroids and antibiotics, among others. At the same time, the risk of infections in these patients remains high because of prolonged hospitalizations or the need for long-timing implanted devices between other features.

A spinal cord injury (SCI) disrupts the neuronal projections from the brain to the region of the spinal cord that produces walking, leading to various degrees of paralysis. Here, we aimed to identify brain regions that steer the recovery of walking after incomplete SCI and that could be targeted to augment this recovery. To uncover these regions, we constructed a space-time brain-wide atlas of transcriptionally active and spinal cord-projecting neurons underlying the recovery of walking after incomplete SCI.

Improved understanding of cancer immunology has gradually brought increasing attention towards cancer-preventive vaccines as an important tool in the fight against cancer. The aim of this approach is to reduce cancer occurrence by inducing a specific immune response targeting tumours at an early stage before they can fully develop. The great advantage of preventive cancer vaccines lies in the potential to harness a less-compromised immune system in vaccine recipients before their immune responses become affected by the advanced status of the disease itself or by aggressive treatments such as chemotherapy.

Multisubunit protein complexes are central to many cellular processes, and studying their activities and structures in vitro requires reconstitution via recombinant expression and purification. Obtaining targets at sufficient purity and scale typically involves screening several protein variants and expression hosts. Existing cloning strategies enable co-expression but are often time-consuming, labor-intensive, and host-specific, or involve error-prone steps.

Background: Thiamine and ascorbic acid have been proposed to mitigate the devastating consequences of sepsis and septic shock. To date, randomized controlled trials have failed to demonstrate a benefit of these therapies and heterogeneity of treatment effect is suspected. In this study, we aimed at assessing the heterogeneity of treatment effect of thiamine (B1) and the combination of B1 plus ascorbic acid (AA + B1) in critically ill patients with sepsis.

The tumour microenvironment is programmed by cancer cells and substantially influences anti-tumour immune responses. Within the tumour microenvironment, CD8 T cells undergo full effector differentiation and acquire cytotoxic anti-tumour functions in specialized niches. Although interactions with type 1 conventional dendritic cells have been implicated in this process, the underlying cellular players and molecular mechanisms remain incompletely understood.

The Albumin-to-Alkaline Phosphatase ratio (AAPR) is an easily applicable and cost-effective marker investigated as an outcome predictor in solid cancers. Preliminary evidence in breast cancer suggests that a low AAPR correlates with a poor response to neoadjuvant chemotherapy (NAC) in primary tumors. However, data regarding the axillary response are lacking.

This work proposes a new method to assess the performance of radiographic anti-scatter grids (ASGs) without the use of a narrow primary beam, which is difficult to achieve.Three general purpose ASGs were evaluated, two marketed ASGs and a low frequency and high ratio prototype ASG with molybdenum lamellae. A range of high scatter x-ray beams were used in a standardized geometry, with energies ranging from 60 kV to 121 kV, for five beam sizes between 10 × 10 and 30 × 30 cm.

Purpose: Revisional bariatric surgery (RBS) has flourished during the last decades in many countries, due to suboptimal weight loss or long-term complications of primary bariatric surgery. Restrictive procedures, and in particular sleeve gastrectomy (SG), although widely performed as primary bariatric surgery, seems particularly prone to need surgical revision for the above-mentioned reasons during long-term follow-up. The aim of this systematic review was to compare the long-term (5-year) safety and efficacy between Roux-en-Y gastric bypass (RYGB) and single anastomosis duodeno-ileal bypass (SADI) after 'failed' SG.

Poly-ADP-ribose polymerase inhibitors (PARPis) have revolutionized the management of BRCA-mutated (BRCA) and homologous recombination deficiency (HRD)-positive ovarian cancer (OC). While long-term analyses clearly support the use of PARPi as maintenance therapy after first-line chemotherapy, recent data have raised concerns on detrimental overall survival (OS) in non-BRCA OC, a greater incidence of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), and unfavorable outcomes following subsequent platinum-based chemotherapy in pretreated OC patients. In this report we discuss the long-term follow-up results from phase III trials in pretreated OC patients, which led to the Food and Drug Administration's withdrawal of PARPi indications in this setting.

Ex vivo activation is a prerequisite to reaching adequate levels of gene editing by homology-directed repair (HDR) for hematopoietic stem and progenitor cell (HSPC)-based clinical applications. Here, we show that shortening culture time mitigates the p53-mediated DNA damage response to CRISPR-Cas9-induced DNA double-strand breaks, enhancing the reconstitution capacity of edited HSPCs. However, this results in lower HDR efficiency, rendering ex vivo culture necessary yet detrimental.
