Purpose: Formal coercion in psychiatry is widely studied yet much less is known about pressures patients may experience, partly because of the very few measures available. The goal of this study was to validate the P-PSY35 (Pressures in Psychiatry Scale) and provide a paper-and-pencil and a computerised adaptive test (CAT) to measure pressures experienced by patients in psychiatry.

Methods: The P-PSY35 items were developed with users.

Background: Coercion perceived by psychiatric inpatients is not exclusively determined by formal measures such as involuntary admissions, seclusion or restraint, but is also associated with patients' characteristics and professionals' attitude.

Aims: This study examined how inpatients' involvement in the decision making process, the respect of their decision making preference, and their feeling of having been treated fairly mediate the relationship between involuntary hospitalisation and perceived coercion both at admission and during hospital stay.

Methods: Mediation analysis were performed in order to study the relationship between involuntary hospitalisation and perceived coercion among 230 patients, voluntarily and involuntarily admitted in six psychiatric hospitals.

Informal caregivers of people with severe mental illness are particularly at risk of experiencing high levels of burden and perceived stress, which can worsen their global health. In addition, the semi-confinement in 2020 represented a period of additional difficulties for informal caregivers in French-speaking of Switzerland. The burden represents all the negative consequences linked to the informal caregiver role.

Article Synopsis
  • Liquid biopsy, specifically plasma ctDNA analysis, has potential but its effectiveness in capturing detailed tumor characteristics for clinical use is still being explored.
  • In a study with 459 metastatic breast cancer patients, machine learning techniques were applied to ctDNA to uncover complex biological features similar to traditional tumor tissue analysis.
  • The research identified four DNA subtypes and a specific ctDNA genomic signature linked to poor treatment response and survival outcomes, highlighting the potential for ctDNA to serve as a valuable predictor in cancer treatment.

The patient recovery process of individual with mental health disorder is reinforced if they are connected with their community and supported by relatives. The literature has shown that caregivers are important, although their roles can lead to alterations in their own health; and women are the most involved in this role. The present review investigated women's involvement in the informal caregiver scientific field.

Coercion in psychiatry is associated with several detrimental effects, including in the long term. The effect of past experience of coercion on the perception of subsequent hospitalisations remains less studied. The present study aimed to assess the impact of past experience of coercion on the perception of coercion and satisfaction with subsequent voluntary hospitalisations.

Article Synopsis
  • * The study identified AXL overexpression as a crucial factor in resistance to trastuzumab, which activates specific pathways that reduce treatment effectiveness.
  • * Targeting AXL, either through genetic modifications or inhibitors, restored sensitivity to trastuzumab and could serve as a prognostic biomarker in HER2-positive breast cancer patients.

Article Synopsis
  • - The study introduces the HER2DX risk score and pCR score, which utilize a combination of 27 gene expressions and clinical features to predict survival and treatment responses in early-stage HER2-positive breast cancer.
  • - HER2DX analyzes factors like tumor size and immune response, using training data from a large cohort of HER2-positive tumors and validating its effectiveness with additional independent cohorts.
  • - Results show that the HER2DX risk score is significantly linked to disease-free survival, with low-risk patients having a high 5-year survival rate. Additionally, the pCR likelihood score predicts the likelihood of achieving complete response to treatment with high accuracy.

Objectives: Serum indices included in clinical chemistry instruments are widely used by laboratories to assess the quality of samples. Instruments that report quantitative results allow an evaluation of their diagnostic performance in a similar way to other biochemical tests. The Spanish Society of Laboratory Medicine (SEQC-ML) launched a monthly External Quality program of serum indices in 2018 using three lyophilized materials of simultaneous annual distribution.

Article Synopsis
  • Atezolizumab, an immune checkpoint inhibitor, is usually approved for PD-L1-positive triple-negative breast cancer (TNBC), but it hasn’t shown effectiveness in PD-L1-negative cases until now.
  • A case study revealed a woman with PD-L1-negative TNBC and low tumor infiltrating lymphocytes who responded remarkably well to atezolizumab alone, and an even better response when combined with nab-paclitaxel.
  • Comprehensive genomic analysis of her tumor indicated high tumor mutational burden and other specific genetic markers, suggesting these factors may help predict responses to immunotherapy in TNBC, pointing towards the need for further research on biomarkers beyond PD-L1 expression.

Purpose: The prognostic and predictive value of intrinsic subtypes in hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer treated with endocrine therapy and ribociclib (RIB) is currently unknown. We evaluated the association of intrinsic subtypes with progression-free survival (PFS) in the MONALEESA trials.

Methods: A retrospective and exploratory PAM50-based analysis of tumor samples from the phase III MONALEESA-2, MONALEESA-3, and MONALEESA-7 trials was undertaken.

Circulating tumor DNA (ctDNA) levels may predict response to anticancer drugs, including CDK4/6 inhibitors and endocrine therapy combinations (CDK4/6i+ET); however, critical questions remain unanswered such as which assay or statistical method to use. Here, we obtained paired plasma samples at baseline and week 4 in 45 consecutive patients with advanced breast cancer treated with CDK4/6i+ET. ctDNA was detected in 96% of cases using the 74-gene Guardant360 assay.

Immunotherapy has transformed advanced non-small cell lung cancer (NSCLC) treatment strategies and has led to unprecedented long-lasting responses in some patients. However, the molecular determinants driving these long-term responses remain elusive. To address this issue, we performed an integrative analysis of genomic and transcriptomic features of long-term immune checkpoint inhibitors (ICIs)-associated responders.

Trastuzumab emtansine (T-DM1) is approved for the treatment of human epidermal growth factor receptor 2 (HER2)-positive (HER2+) metastatic breast cancer (BC) and for residual disease after neoadjuvant therapy; however, not all patients benefit. Here, we hypothesized that the heterogeneity in the response seen in patients is partly explained by the levels of human epidermal growth factor receptor 2 gene mRNA. We analyzed expression using a clinically applicable assay in formalin-fixed paraffin-embedded (FFPE) tumors (primary or metastatic) from a retrospective series of 77 patients with advanced HER2+ BC treated with T-DM1.
