Aims: To determine patterns of e-cigarette flavour use (sweet, tobacco, menthol/mint) in interventional studies of e-cigarettes for stopping smoking, and to estimate associations between flavours and smoking/vaping outcomes.

Methods: Update of secondary data analyses, including meta-analyses subgrouped by flavour provision and narrative syntheses, incorporating data from January 2004 to February 2024. Eligible studies were identified from a Cochrane review.

Objective: Most cancer patients undergoing hematopoietic stem cell transplant report elevated symptoms and reduced health-related quality of life during peritransplant. These concerns can become persistent. A prior randomized controlled trial showed that expressive helping-a low-burden, brief intervention combining expressive writing with a novel peer support writing exercise-reduced psychological distress and physical symptoms in long-term transplant survivors with moderate/high persistent symptoms.

Drug-resistant microbes typically carry mutations in genes involved in critical cellular functions and may therefore be less fit under drug-free conditions than susceptible strains. Candida glabrata is a prevalent opportunistic yeast pathogen with a high rate of fluconazole resistance (FLZR), echinocandin resistance (ECR), and multidrug resistance (MDR) relative to other Candida. However, the fitness of C.

Article Synopsis
  • * Resistance mutations in the β-glucan synthase genes (FKS1 and FKS2) are linked to treatment failures, but other unidentified factors influence echinocandin susceptibility.
  • * Research on C. glabrata in mice treated with caspofungin revealed rapid genetic changes, including mutations in the FEN1 gene that increase resistance by affecting phytosphingosine levels, which also occurs in clinical strains.

Objective: To quantify the effect of neighborhood socioeconomic vulnerability as it relates to racial disparity in uterine cancer treatment and survival.

Methods: Patients with a diagnosis of uterine cancer who underwent hysterectomy in New York State from 2004 to 2017 were included in this retrospective cohort study. Neighborhood socioeconomic vulnerability as quantified by the Area Deprivation Index was calculated.

  • Metastases, which are the spread of cancer cells to different organs, play a crucial role in the severity of renal cell carcinoma (RCC), with common sites being the lungs, bones, liver, and lymph nodes.
  • This study analyzed 657 tumor samples from both primary renal tumors and various metastatic sites to identify genomic and transcriptomic differences.
  • The findings reveal significant variations in tumor characteristics and the tumor microenvironment across different metastatic locations, highlighting the importance of these factors in creating targeted cancer treatments.

Pancreatic cancer is one of the most lethal malignancies, yet much remains to be learned regarding how its precursors develop. In a recent Nature publication, Braxton and Kiemen et al. found that the normal, adult pancreas harbors hundreds to thousands of pancreatic cancer precursors evolving by a variety of routes.

This manuscript describes the Advanced Breast Cancer (ABC) international consensus guidelines updated at the last two ABC international consensus conferences (ABC 6 in 2021, virtual, and ABC 7 in 2023, in Lisbon, Portugal), organized by the ABC Global Alliance. It provides the main recommendations on how to best manage patients with advanced breast cancer (inoperable locally advanced or metastatic), of all breast cancer subtypes, as well as palliative and supportive care. These guidelines are based on available evidence or on expert opinion when a higher level of evidence is lacking.

Background: We estimated the prevalence and mortality risks of preserved ratio impaired spirometry (PRISm) and chronic obstructive pulmonary disease (COPD) in the US adult population.

Methods: We linked three waves of pre-bronchodilator spirometry data from the US National Health and Nutritional Examination Survey (2007-2012) with the National Death Index. The analytic sample included adults ages 20 to 79 without missing data on age, sex, height, BMI, race/ethnicity, and smoking status.

Article Synopsis
  • The study aimed to analyze the outcomes of different mammography screening strategies for breast cancer, focusing on various start and stop ages as well as screening intervals.
  • Using six cancer modeling models, the research found that biennial digital breast tomosynthesis (DBT) screening starting at ages 40, 45, or 50 significantly reduced breast cancer deaths, with the most effective strategy a 30% reduction in mortality for those screened from age 40 to 74.
  • While annual screening offered higher benefits, it also led to increased false-positive recalls and overdiagnosis, showing a critical need to balance benefits against potential harms in screening recommendations.

Article Synopsis
  • - This study explored the gene expression differences between clear cell renal cell carcinoma (ccRCC) and non-clear cell variants (nccRCC) in a diverse patient group to improve treatment strategies.
  • - ccRCC tumors showed a stronger connection to angiogenesis, while different nccRCC subtypes had elevated scores in areas like cell cycle and fatty acid metabolism.
  • - Both tumor types displayed T effector scores linked to higher immune cell activity, suggesting potential benefits for immunotherapy, highlighting the need for tailored treatment plans based on tumor type.

Purpose: Cancer survivors commonly report cognitive declines after cancer therapy. Due to the complex etiology of cancer-related cognitive decline (CRCD), predicting who will be at risk of CRCD remains a clinical challenge. We developed a model to predict breast cancer survivors who would experience CRCD after systematic treatment.

Unlabelled: Recent epidemiological studies documented an alarming increase in the prevalence of echinocandin-resistant (ECR) blood isolates. ECR isolates are known to arise from a minor subpopulation of a clonal population, termed echinocandin persisters. Although it is believed that isolates with a higher echinocandin persistence (ECP) are more likely to develop ECR, the implication of ECP needs to be better understood.

is a major fungal pathogen, which is able to lose mitochondria and form small and slow-growing colonies, called "petite." This attenuated growth rate has created controversies and questioned the clinical importance of petiteness. Herein, we have employed multiple omics technologies and mouse models to critically assess the clinical importance of petite phenotype.

Radiotherapy is a curative cancer treatment modality that imparts damage to cellular DNA, induces immunogenic cell death, and activates antitumor immunity. Despite the radiotherapy-induced direct antitumor effect seen within the treated volume, accumulating evidence indicates activation of innate antitumor immunity. Acute proinflammatory responses mediated by anticancer M1 macrophages are observed in the immediate aftermath following radiotherapy.

Candida parapsilosis is one of the most commen causes of life-threatening candidaemia, particularly in premature neonates, individuals with cancer of the haematopoietic system, and recipients of organ transplants. Historically, drug-susceptible strains have been linked to clonal outbreaks. However, worldwide studies started since 2018 have reported severe outbreaks among adults caused by fluconazole-resistant strains.

Candida glabrata is a major fungal pathogen notable for causing recalcitrant infections, rapid emergence of drug-resistant strains, and its ability to survive and proliferate within macrophages. Resembling bacterial persisters, a subset of genetically drug-susceptible C. glabrata cells can survive lethal exposure to the fungicidal echinocandin drugs.

Multiple large-scale tumor genomic profiling efforts have been undertaken in osteosarcoma, however, little is known about the spatial and temporal intratumor heterogeneity and how it may drive treatment resistance. We performed whole-genome sequencing of 37 tumor samples from eight patients with relapsed or refractory osteosarcoma. Each patient had at least one sample from a primary site and a metastatic or relapse site.
