Background: It is currently unknown whether plant-based dietary patterns influence disease progression to multimorbidity after an initial non-communicable disease, and whether the associated risk of multimorbidity varies with age. This study aimed to investigate associations of plant-based diets with the risk of multimorbidity, defined as the co-occurrence of at least two chronic diseases in an individual (either cancer at any site, cardiovascular disease, or type 2 diabetes).

Methods: This prospective cohort study used data from EPIC and UK Biobank across six European countries, with participants aged 35-70 years at recruitment.

While previous literature suggests that plant-based diets may be associated with a lower risk of breast cancer, evidence remains inconsistent. In this study, we investigated the association between adherence to plant-based diets and breast cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Overall plant-based diet index (PDI), healthful (hPDI), and unhealthful PDI (uPDI) were calculated, and multivariable Cox models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of breast cancer for the three indices.

Objectives: Anxiety is strongly associated with chronic musculoskeletal pain, including painful temporomandibular disorders (p-TMD). Non-functional oral behaviors-such as wake-time tooth clenching or keeping the lower jaw in a tense position-are prevalent stress-related behaviors among individuals with elevated anxiety. These behaviors are thought to act as maladaptive coping strategies increasing strain on the masticatory muscles and the temporomandibular joint, thereby enhancing peripheral nociceptive input and contributing to the onset or persistence of p-TMD in individuals with high anxiety.

Background: Postoperative adjuvant epidermal growth factor receptor (EGFR) inhibitor osimertinib is the standard care for stage IB-IIIB non-small-cell lung cancer (NSCLC) with EGFR exon 19 deletions or exon 21 L858R mutation, following complete tumour resection, with or without prior platinum-based adjuvant chemotherapy. However, the role of EGFR tyrosine kinase inhibitors (TKIs) in this setting is debated, particularly concerning long-term curative effects versus recurrence delay. Uncertainties persist around treatment duration, harms, and effectiveness across disease stages, prior chemotherapy, or EGFR-sensitising mutation types.

Neutrophils can promote or suppress tumor growth. These different immunological functions mirror a great heterogenicity of neutrophil maturation and activation status: low-density granulocytes (LDGs) and normal-density neutrophils (NDNs). LDGs participate in immune dysregulation during autoimmune disorders with an activated phenotype, while NDNs might exert immunosuppressive activities.

Background And Aims: It is well known that being overweight or obese is a risk factor for coronary artery disease (CAD). At the same time, belonging to these categories indirectly influences other risk factors like hypertension, diabetes or dyslipidemia also through a chronic inflammation condition. The aim of this study was to establish to which extent the effect of body mass index (BMI) on CAD risk can be explained by the chronic inflammation degree, using a statistical mediation model.

Article Synopsis
  • Previous models for predicting weight gain haven't been very effective, leading researchers to explore both traditional environmental factors and genetic markers to enhance accuracy.* -
  • A study involving nearly 246,000 participants found that environmental factors provided good predictive ability for weight gain, while genetic models performed poorly, especially at mid-late adulthood.* -
  • The research suggests that environmental factors should be incorporated into prevention strategies, and that genetic factors may be more relevant in predicting weight gain earlier in life.*

Article Synopsis
  • In ovarian cancer, a comprehensive study examined various metabolism-related markers to understand their prognostic value, but results showed mixed outcomes in large patient groups.
  • The study used advanced techniques on tissue samples from over 300 patients to analyze markers tied to glycolysis, glutamine metabolism, and hypoxia, but found that only one marker (GLS) hinted at a connection to patient survival, which was not statistically significant after adjustments.
  • Ultimately, the research highlights the diversity of metabolism markers in ovarian cancer and suggests their expression patterns may still be relevant for future drug development, even if they don't currently correlate with treatment outcomes.

Article Synopsis
  • There are currently no specific biomarkers to identify patients with advanced ovarian carcinoma who are responsive to bevacizumab (BEV), a key treatment option.
  • A study analyzed TP53 mutations and p53 expression in advanced ovarian cancer patients undergoing BEV treatment, finding that unclassified missense TP53 mutations significantly improved overall survival.
  • The results suggest that unclassified TP53 mutations could serve as a favorable prognostic indicator in these patients, indicating the need for further research to explore their potential role in predicting treatment outcomes.

Alcohol withdrawal syndrome (AWS) is defined as the cessation or reduction in heavy and prolonged alcohol use within several hours to a few days of cessation. The recommended first-line therapy for AWS ranging from mild to severe or complicated remains benzodiazepines; in cases where benzodiazepines are not adequate in controlling persistent autonomic hyperactivity or anxiety, dexmedetomidine could be utilized. The possible advantage of dexmedetomidine compared to benzodiazepines is that it does not cause respiratory depression, thus reducing the risk of intubation and hospitalization in the ICUs, with the potential reduction in healthcare costs.
