Facilitating Factors and Barriers in the Return to Work of Working Women Survivors of Breast Cancer: A Qualitative Study.

Several studies have identified the main barriers and facilitators that breast cancer survivors experience in the return to work (RTW). The authors conducted a qualitative study using focus group discussions with a group of female non-metastatic breast cancer survivors (n = 6), a group of health professionals from different medical specialties (n = 8), and a third group of company managers mainly composed of human resources managers (n = 7). The study was carried out between March and December 2021 in Zaragoza (Spain). Transcripts were analyzed using inductive content analysis to identify work-related barriers and facilitators and coded by the research team. Barriers identified included physical and cognitive symptoms, psychosocial problems, lack of knowledge and coordination (health professional, patients, and managers), legal vacuum, physical change, time constraints, work characteristics (lower skilled jobs), unsupportive supervisors and coworkers, family problems and self-demand. Facilitators included family and work support, physical activity and rehabilitation, personalized attention, interdisciplinary collaboration, legal advice for workers, knowledge about breast cancer in companies, positive aspects of work, elaboration of protocols for RTW in women with breast cancer. RTW in working women with breast cancer requires a personalized and holistic view that includes the perspectives of patients, healthcare professionals and company managers.

Dietary squalene supplementation decreases triglyceride species and modifies phospholipid lipidomic profile in the liver of a porcine model of non-alcoholic steatohepatitis.

Squalene is a key minor component of virgin olive oil, the main source of fat in the Mediterranean diet, and had shown to improve the liver metabolism in rabbits and mice. The present research was carried out to find out whether this effect was conserved in a porcine model of hepatic steatohepatitis and to search for the lipidomic changes involved. The current study revealed that a 0.5% squalene supplementation to a steatotic diet for a month led to hepatic accumulation of squalene and decreased triglyceride content as well as area of hepatic lipid droplets without influencing cholesterol content or fiber areas. However, ballooning score was increased and associated with the hepatic squalene content. Of forty hepatic transcripts related to lipid metabolism and hepatic steatosis, only citrate synthase and a non-coding RNA showed decreased expressions. The hepatic lipidome, assessed by liquid chromatography-mass spectrometry in a platform able to analyze 467 lipids, revealed that squalene supplementation increased ceramide, Cer(36:2), and phosphatidylcholine (PC[32:0], PC[33:0] and PC[34:0]) species and decreased cardiolipin, CL(69:5), and triglyceride (TG[54:2], TG[55:0] and TG[55:2]) species. Plasma levels of interleukin 12p40 increased in pigs receiving the squalene diet. The latter also modified plasma lipidome by increasing TG(58:12) and decreasing non-esterified fatty acid (FA 14:0, FA 16:1 and FA 18:0) species without changes in total NEFA levels. Together this shows that squalene-induced changes in hepatic and plasma lipidomic profiles, non-coding RNA and anti-inflammatory interleukin are suggestive of an alleviation of the disease despite the increase in the ballooning score.
