The storage of serum tumor markers (STM) at −18 °C for one year has been a legal requirement in France since 1999, but has been abolished in 2022. This raises the question of the relevance of maintaining these biobanks in terms of conditions of storage. These should only be implemented after validation; in order to maintain the integrity of the biological sample and must be controlled over time according to the laboratoryʼs procedures. The aim of the study was to assess the suitability of storing 10 STMs by evaluating their stability after one year of storage at −18 °C. A new immuno-enzymatic assay (A+1) was conducted on samples that had been stored at −18 °C for one year after an initial assay (A) of one of the following STMs: carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), carbohydrate antigen 125 (CA125), carbohydrate antigen 15-3 (CA15-3), carbohydrate antigen 19-9 (CA19-9), total (TPSA), and free (FPSA) prostate-specific antigen, calcitonin (CT), thyroglobulin (TG), and neuro-specific enolase (NSE). The results were confronted to four different permissible error sources. In total, 1148 A+1 assays were performed. A strong correlation between A+1 and A values was found for all analytes, but with a statistically significant reduction in the mean A+1 concentration compared to the mean A concentration in 7/10 STMs. The bias induced by conservation seems to be technically unsustainable if we rely on the repositories closest to the current analytical performances. These results support the discontinuation of mandatory STM biobank storage at −18 °C, which requires considerable technical time and organizational effort. [ABSTRACT FROM AUTHOR]

Two studies explored the conditions under which readers update their representation of news reports in the presence of alternative plausible explanations for a target event. To do so, this study asked readers to read news reports that mentioned 2 different causes to explain the occurrence of a single event. This study manipulated which of the 2 causes was emphasized at the end of the news report. Experiment 1, through an inference judgment task and a simulation using the Landscape Model, evaluated which of the 2 potential causes was represented in the readers' final situation model. Experiment 2 collected think-aloud protocols to investigate the content of readers' thoughts when they were faced with alternative plausible explanations in accounts of a single event. The findings indicate that readers update their representation as new causes appear in the text but that the nature of the updating is a function of the order of presentation of the causes: They either select 1 cause over another or draw causal inferences between the 2 causes to maintain the coherence of their situation models under construction. These findings are discussed within the theoretical framework of the Landscape Model. (Contains 2 figures and 1 table.)

Approximately 7% of breast cancers are diagnosed in women under 40. Question of subsequent fertility has become fundamental. We aimed to evaluate the rate of fertility preservation (FP) by oocyte retrieval (OR) after ovarian stimulation in patients of childbearing age, managed for breast cancer with adjuvant chemotherapy in France, reuse rate of frozen gametes and live births rate (LBR) after treatment. We included 15,774 women between 18 and 40 years old, managed by surgery and adjuvant chemotherapy for breast cancer, between January 2011 and December 2020 from a French health registry. Patients with OR after breast surgery and before chemotherapy were considered as FP group; those with no OR as no FP group. To compare LBR with French population independently of age, we calculated Standardized Incidence Rates (SIR) of live births using indirect standardization method. FP rate increased gradually since 2011, reaching 17% in 2019. A decrease in use was observed in 2020 (13,9%). Among patients with at least 2 years of follow-up, gamete reuse rate was 5,6%. Births after cancer were mostly from spontaneous pregnancies. Among patients with at least 3 years of follow-up, LBR was 19,6% in FP group, 3,9% in second group. SIR of live births was of 1,05 (95% CI = 0.91–1.19) and 0.33 (95% CI = 0.30–0.36) in FP and no FP group respectively. Oncofertility activity increased until 2019 in France, reaching 17%. Gamete reuse rate was low. Births resulted mainly from spontaneous pregnancies. SIR of live births was lower in no FP group. • Fertility preservation rate increased gradually since 2011, reaching 17% in 2019. • Among patients with at least 2 years of follow-up, gamete reuse rate was 5,6%. • Births after breast cancer were mostly from spontaneous pregnancies. • Life births rate was 19,6% in fertility preservation group, 3,9% in second group.

Aim The MCQ is a seven-factor scale that measures individual differences in the tendency to select particular strategies and to overcome perceived or real memory losses. Our aim was to establish a French version of the MCQ and to evaluate its psychometric properties in a lifespan perspective. We first tested the underlying factor structure of the MCQ in a large sample of 749 adults from aged from 18 to 92 years. Results The results showed that the factor structure of the French version corresponded well with the one obtained in English-, Dutch- and Spanish-speaking samples, supporting the cross-national robustness of the MCQ. We confirmed a seven-factor order model that supports the construct validity of the questionnaire. The reliabilities of the scales were good ( α > .70) to acceptable ( α = .66 and .62). Criterion validity was verified by means of significant correlations between health composites and MCQ subscales. Gender and Age affected most of the MCQ subscales but not the Level of Education (LE). Conclusion The MCQ revealed to be a heuristic tool for assessing daily compensatory behaviors that are developed in order to achieve successful aging. Thus, regression-based normative data and a user-friendly computer program were provided to facilitate scoring and norming by clinicians and researchers who need to assess daily compensatory behaviors.
