RESUMEN
PURPOSE: Acting on modifiable risk factors can prevent approximately 40% of cancers. Knowing the factors that lead people to adopt healthy behaviors is crucial for designing effective primary prevention campaigns. Our study attempts to provide knowledge in this direction. METHODS: This cross-sectional study was conducted via the Seintinelles collaborative research platform in a community of women without a personal cancer history, and volunteering to take online questionnaires. We collected data on sociodemographic and health factors, knowledge of cancer risk factors, behaviors, and possible behavior changes (tobacco/alcohol use, diet, body weight, and physical activity) in the last 10 years. RESULTS: The study involved 1465 women aged between 18 and 84 years. Factors such as young age, living alone, and obesity were associated with some positive or negative behavior changes. Being professionally active and having comorbidities favored certain positive behavior changes, while having dependent children, living in a rural area, and being hospitalized were associated with negative or no change in behaviors. Lack of knowledge about modifiable risk factors for cancer was associated with the non-adoption of various healthy behaviors (consumptions of fruit and vegetables, processed and red meat; physical activity). Only 5.5% of participants currently reported to be compliant with seven public health recommendations (smoking; alcohol, fruit/vegetables, and red/processed meat intakes; body mass index; and physical activity). CONCLUSIONS: This study allowed to identify the need to increase the level of knowledge on modifiable risk factors for cancer among the general population and to better clarify the content of prevention messages.

BACKGROUND: Health-Related Quality of life (HRQoL) in cancer survivors can be significantly affected in the long-term by various consequences resulting from differing levels of severity of cancer and its treatments. Our objective was to identify factors associated with HRQoL in breast cancer survivors (BCSs) and cancer-free women (CFWs). METHODS: We conducted a cross-sectional study in Seintinelles volunteers who answered online questionnaires between September 15, 2020 and February 5, 2021. HRQoL was measured using the World Health Organization Quality of Life-BREF questionnaire. We collected data on sociodemographic and health-related factors, lifestyle habits, coping mechanisms, locus of control, and health literacy. SAS version 9.4 statistical software was used for analyses. We performed descriptive analyses of the characteristics of the participants in each group and compared these characteristics between the two groups using the Chi2 test or the Student t-test. The adjusted means of the scores of different psychometric scales were calculated and compared using the method of least squares to fit general linear models (GLM) while adjusting for various factors. Multiple linear or multiple logistic regression models were used to assess the factors associated with WHOQOL-BREF scores, separately, in the two groups of participants. RESULTS: The study involved 722 BCSs and 1359 CFWs aged 26-75 years. BCSs had significantly lower physical health scores and were less likely to be satisfied with their health compared to CFWs (59.5 vs. 63.2, p < 0.0001; and 56.5% vs. 75.2%, p = 0.002, respectively). In both groups, some common factors were positively associated with physical health (high financial level, being professionally active, normal BMI, good health status, alcohol consumption, higher values (> 22) of internal locus of control); or inversely associated (neurological and sleep problems, over two medical consultations/year). In BCSs, treatment by mastectomy or radiation therapy/brachytherapy, a short-time since diagnosis, current cancer therapy, and presence of sequalae were inversely associated with physical health. BCSs' health satisfaction was diminished with lower values of coping by positive thinking (≤ 14) and seeking social support (≤ 18). CONCLUSIONS: HRQoL can be improved by developing strategies that increase internal locus of control and coping (positive thinking, problem-solving and seeking social support), and through health literacy.

Health-related quality of life (HRQoL) is a multidimensional concept including physical, emotional, social, and cognitive functions, disease symptoms, and side effects of treatment. Differences in HRQoL due to gender, existence of comorbidities, and number of chemotherapy cycles are little explored in diffuse large B-cell lymphoma (DLBCL) survivors. Our objective was to investigate whether differences in HRQoL in function of these factors exist 1 year after the diagnosis of DLBCL. One hundred and one patients, enrolled in the RT3 (Real-Time Tailored Therapy) Study, answered self-administrated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), EORTC High-Grade Non-Hodgkin Lymphoma (NHL-HG29), Hospital Anxiety and Depression Scale (HADS), Post Traumatic Growth Inventory (PTGI), and Multidimensional Fatigue Inventory (MFI) questionnaires. Adjusted means of scores were calculated in multivariate linear regression models. Fifty-seven survivors (mean age of 58.5 years) answered all questionnaires. Women have significantly higher scores of posttraumatic growth and lower physical functioning than men (P < 0.04). Survivors with comorbidities have increased physical fatigue and symptom burden, increased emotional impact, mental fatigue and depression, and reduced physical functioning and global health status (all P < 0.05). A greater number of cycles of chemotherapy increase the level of symptoms (pain, neuropathy, and dyspnoea; P < 0.05). The various aspects related to HRQoL should be discussed with DLBCL patients and investigated, with the aim of developing strategies to ensure appropriate psychosocial and supportive care and to improve the HRQoL in these patients.

BACKGROUND: Aboriginal populations living in Canada's northern regions are exposed to a number of persistent organic pollutants through their traditional diet which includes substantial amounts of predator fish species. Exposure to dioxin-like compounds (DLCs) can cause a variety of toxic effects including adverse effects on bone tissue. This descriptive cross-sectional study was conducted to investigate the relationship between plasma concentrations of DLCs and bone quality parameters in Cree women of Eastern James Bay (Canada). METHODS: Two hundred and forty-nine Cree women from seven communities in Eastern James Bay (Canada), aged 35 to 74 years old, participated in the study. In order to determine the total DLC concentration in plasma samples of participants, we measured the aryl hydrocarbon receptor-mediated transcriptional activity elicited by plasma sample extracts using a luciferase reporter gene assay. Plasma concentrations of mono-ortho-substituted dioxin-like polychlorinated biphenyls (DL-PCBs) 105, 118 and 156 were measured by gas chromatography-mass spectrometry. Bone quality parameters (speed of sound, m/s; broadband ultrasound attenuation, dB/MHz; stiffness index, %) were assessed by quantitative ultrasound at the right calcaneus with the Achilles InSight system. Several factors known to be associated with osteoporosis were documented by questionnaire. Multiple linear regression models were constructed for the three ultrasound parameters. RESULTS: DL-PCBs 105 and 118 concentrations, but not the global DLC concentration, were inversely associated with the stiffness index, even after adjusting for several confounding factors. The stiffness index (log) decreased by -0.22% (p=0.0414) and -0.04% (p=0.0483) with an increase of one µg/L in plasma concentrations of DL-PCB 105 and DL-PCB 118, respectively. Other factors, including age, height, smoking status, menopausal status and the percentage of omega-6 polyunsaturated fatty acids (PUFAs) in erythrocyte membranes were negatively associated with one of the ultrasound parameters, while the percentage of omega-3 PUFAs in these membranes and levels of physical activity and education were positively associated with them. CONCLUSIONS: Our results show that an increase in plasma concentrations of DL-PCBs 105 and 118 was negatively associated with stiffness index, a measure of bone quality/strength, in women of this population. In addition to environmental contaminants, future studies should also consider PUFA intake as a factor influencing bone quality.

INTRODUCTION: The number of cancer survivors increases and their risks of recurrence, second cancer, morbidity and death is high; measures to prevent these risks are thus critical. Knowing the factors that lead cancer survivor to adopt or not healthy behaviours is crucial for designing effective prevention campaigns and better support them in after-cancer. Our study attempts to provide additional knowledge in this direction. METHODS: This retrospective study was conducted via the Seintinelles collaborative research platform in a community of women with cancer volunteering to take online questionnaires. We collected data on sociodemographic factors and health, knowledge of cancer risk factors, and possible behaviour changes (tobacco/alcohol use, diet, physical activity) after cancer diagnosis. RESULTS: The study involved 1180 women aged between 26 and 79 years. Several cancer-related factors (cancer other than breast cancer, longer time since diagnosis, taking drug treatment for cancer, sequelae, negative evolution of the cancer) favoured certain positive changes in behaviour. Sociodemographic factors (age, habitat environment, currently employed, living status, dependent children) or factors related to health (general condition, presence of comorbidities, neurological problems, hospitalizations, body mass index) favoured or not certain changes in behaviour. Lack of knowledge about modifiable risk factors for cancer was associated with not adopting healthy behaviours after cancer. DISCUSSION: This study made it possible to identify important elements to be addressed in order to improve cancer risk prevention messages.

Basal cell carcinoma (BCC) is considered to be the most common cancer in humans. It has a slow growth rhythm, and for this reason, metastases are rare. For our retrospective study, we selected 180 patients from those who underwent surgery for a variety of skin tumours between January 2019 and August 2022 and whose histopathological examination revealed basal cell carcinoma. All surgeries were performed by plastic surgeons at the "St. John" hospital in Bucharest. The aim of this article is to provide observational data regarding BCC-in terms of histopathology and diagnostic and therapeutic management and to integrate these data into the current knowledge of this pathology.
RESUMEN
INTRODUCTION: Taxi drivers could be at risk regarding their respiratory health due to their constant exposure to traffic related air pollutants (TRAP) inside their vehicles. Therefore, we aimed to review pollutants exposure inside taxi vehicles and its determinants as well as its acute adverse respiratory effects. METHODS: The literature search was done in Pubmed and in Embase. For additional resources we searched manually articles from the reference lists of the selected papers and from Google Scholar. We included only studies in French or in English language meeting the following eligibility criteria: design: observational and quasi-experimental; study population: taxi drivers or taxi commuters, outcome: pollutants levels in taxicabs and/or acute adverse respiratory effects. Data was extracted using tabulation according to the type of the study (exposure or epidemiological). RESULTS: Out of 1753 articles, 21 studies were included. Exposure studies underlined that TRAP concentrations inside taxicabs were higher than their urban background levels and even exceeded those recorded in buses, in trains and when commuting by active transport modes. Overall, their concentrations varied widely between studies depending on the characteristics of the urban environment and the vehicle fleet of each location. Meteorological parameters and ventilation settings appeared to influence pollutants concentrations inside each vehicle. Otherwise, deficiency in epidemiological studies and inconsistencies in their findings restrain our ability to determine the association between acute respiratory effects and exposure to TRAP inside taxicabs. CONCLUSION: Although studies are heterogeneous, results have shown a high but variable occupational exposure of taxi drivers to TRAP inside their vehicles. However, future researches are required to study short respiratory impact of taxi drivers' exposure to TRAP inside their vehicles.

BACKGROUND: Few studies have investigated the 24-hour respiratory health effects of personal black carbon (BC) and ultrafine particles (UFP) exposure in schoolchildren. The objective of this study was to investigate these associations with the lung function in children 10-years old with and without persistent respiratory symptoms. METHODS: We conducted a cross-sectional study in 305 children (147 and 158 with and without persistent respiratory symptoms, respectively) from three European birth-cohorts: PARIS (France) and INMA Sabadell and Valencia (Spain). Personal 24-hour measurements of exposure concentrations to BC and UFP were performed by portable devices, before lung function testing. Forced expiratory volume in 1â¯s (FEV1), forced vital capacity (FVC) and the fraction of exhaled nitric oxide (FeNO) were determined. RESULTS: There was no association of UFP with lung function parameters or FeNO whereas the increase in 24-hour BC exposure concentrations was related to a statistically significant decrease in lung function parameters only among children with persistent respiratory symptoms [-96.8â¯mL (95% Confidence Interval CI: -184.4 to -9.1â¯mL) in FVC, and -107.2â¯mL (95% CI: -177.5 to -36.9â¯mL) in FEV1 for an inter-quartile range of 1160â¯ng/m3 exposure increase]. A significant positive association between BC and FeNO was observed only in children with persistent respiratory symptoms with current wheezing and/or medication to improve breathing [FeNO increases with +6.9â¯ppb (95% CI: 0.7 to 13.1â¯ppb) with an inter-quartile range BC exposure increase]. CONCLUSION: Children suffering from persistent respiratory symptoms appear to be more vulnerable to BC exposure.

BACKGROUND: Bone strength in Inuit people appears lower than that of non-Aboriginals. Inuit are exposed to persistent organic pollutants including dioxin-like compounds (DLCs) through their traditional diet that comprises predatory fish and marine mammal fat. Results from experimental and population studies suggest that some DLCs can alter bone metabolism and increase bone fragility. OBJECTIVE: This cross-sectional descriptive study was conducted to examine the relationship between the stiffness index (SI) and plasma concentrations of total DLCs or specific dioxin-like polychlorinated biphenyls (DL-PCBs) in Inuit women of Nunavik (Northern Quebec, Canada). METHODS: SI was determined by ultrasonography at the right calcaneus of 194 Inuit women aged 35-72 years who participated to Qanuippitaa? How Are We? Nunavik Inuit Health Survey in 2004. Plasma total DLC levels were quantified by measuring the aryl hydrocarbon receptor-mediated transcriptional activity elicited by plasma sample extracts in a cell-based reporter gene assay. Plasma concentrations of DL-PCBs nos. 105, 118, 156, 157, 167 and 189 were measured by gas chromatography-mass spectrometry. We used multiple linear regression analyses to investigate relations between total DLCs or specific DL-PCBs and SI, taking into consideration several potential confounders. RESULTS: Neither total plasma DLCs nor specific DL-PCBs were associated with SI after adjustment for several confounders and covariates. CONCLUSION: Our results do not support a relation between exposure to DLCs and bone strength measured by ultrasonography in Inuit women of Nunavik.

BACKGROUND: The traditional diet of Inuit people comprises large amounts of fish and marine mammals that are rich in omega-3 polyunsaturated fatty acids (PUFAs). Results from in vitro studies, laboratory animal experiments and population studies suggest that omega-3 PUFA intake and a high omega-3/omega-6 ratio exert a positive effect on bone health. OBJECTIVE: This longitudinal study was conducted to examine the relationship between omega-3 and omega-6 PUFA status and quantitative ultrasound (QUS) parameters in Greenlandic Inuit women. METHODS: The study included 118 Inuit women from Nuuk (Greenland), aged 49-64 years, whose QUS parameters measured at baseline (year 2000), along with PUFA status and covariates, and follow-up QUS measurements 2 years later (year 2002). QUS parameters [speed of sound (SOS); broadband ultrasound attenuation (BUA)] were measured at the right calcaneus with a water-bath Lunar Achilles instrument. Omega-3 and omega-6 PUFA contents of erythrocyte membrane phospholipids were measured after transmethylation by gas chromatography coupled with a flame ionization detector. Relationships between QUS parameters and different PUFAs were studied in multiple linear regression models. RESULTS: Increasing values of EPA, DHA and the omega-3/omega-6 PUFA ratio were associated with increased BUA values measured at follow-up (year 2002). These associations were still present in models adjusted for several confounders and covariates. We found little evidence of associations between PUFAs and SOS values. CONCLUSION: The omega-3 PUFA intake from marine food consumption seems to have a positive effect on bone intrinsic quality and strength, as revealed by higher BUA values in this group of Greenlandic Inuit women.
