“…An association between rotating night work and breast cancer and a positive trend between cancer risk and duration of night work and number of consecutive night shifts were found in American nurses [17,18] and in Norwegian nurses [19,20]. Exposure to light at night has been hypothesized to influence this cancer risk among persons with night work, as a result of a decrease in of the secretion hormone melatonin, and a subsequent increase in estrogens [21][22][23]. The International Agency for Research on Cancer decided that shift work involving circadian disruption is probably carcinogenic for human [24].…”

Introduction and objective. Working at night and in shifts, as well as an unhealthy lifestyle, may increase the risk of breast cancer in nurses who therefore should frequently perform breast self-examination (BSE). The aim of the study was to investigate the performance of BSE among Polish nurses, its accuracy, sources of knowledge and skills, self-assessment of own competences and preparation to educate women about BSE. Materials and method. A descriptive, cross-sectional study was conducted in a group of female nurses (N=1,242). An anonymous, self-administrated questionnaire was used for data collection. To properly assess the BSE a four-item scale was made of the type single best answer multiple choice question. Each item referred to one agreed principle of performing BSE. Results. Regularly BSE was performed by 56.1% nurses, 67.3% pre-menopause nurses 2-3 days after cessation of menstruation and 30.4% post-menopause women on a chosen day of the month. About 98% examined visually and by palpation; 58.9% did so in two positions. In the accuracy scale of BSE, the average number of points was 2.8 out of 4. All (4 points) or almost all (3 points) recommendations of accurate BSE were met by 61.4% of the nurses. Self-assessment of knowledge and BSE practical skills were considered as good or very good by 93.5% and 88.8% nurses, respectively. The self-evaluation of nurses' knowledge and BSE skills was significantly correlated with the result on the accuracy scale or this BSE. Conclusions. Many deficiencies concerning frequency, times and BSE techniques were revealed among Polish nurses. There is a discrepancy between the high self-assessment of competences and the accurate practice of BSE. Nurses' preparation in Poland in BSE is insufficient and requires improvement.

“…Six studies employed samples with only females (Chung et al., ; Futenma et al., ; Peplonska et al., ; Petrov et al., ; Yazdi et al., ; Yoshizaki et al., ). Some authors opted for this approach because the proportion of men was low (Futenma et al., ; Yoshizaki et al., ) or because their inclusion modified the results for a dependent variable (e.g., the food behaviour questionnaire) (Yoshizaki et al., ).…”

Aim To synthesize evidence about the effect of individual circadian preference (chronotype) and gender in the development of sleep and mood problems in nursing professionals. Background Shift workers are more prone to having unhealthy habits and unfavourable clinical conditions than nonshift workers. These associations are mediated by chronotype and gender differences have also been detected. Design A quantitative systematic review. Data sources Electronic searches were performed in MEDLINE, Scopus, ScienceDirect, and Web of Science from 1 July 2012 ‐ 1 July 2017. Review methods A systematic review was conducted using the Cochrane Collaboration guidelines and two quality assessment tools: the National Heart, Lung and Blood Institute and GRADE. Inclusion criteria were quantitative studies where the sample consists entirely of nurses, analysing circadian rhythms or individual chronotype or gender and sleep/mood disturbances in nursing activity. The review was reported using the PRISMA statement. Results A total of 23 studies were included in the review (five cohort studies and 18 cross‐sectional studies). Data on gender‐specific attention were scarce (two studies) and showed a higher incidence of sleep problems. Female nurses with eveningness‐oriented personality seem to be more prone to having sleep disorders, insomnia, fatigue, and anxiety than male and morningness ones. Conclusions Evidence seems to show that female nurses with an evening‐oriented preference suffer more problems of insomnia, sleepiness, fatigue, and anxiety. The impact of our results may affect nurses, patient safety and the quality of clinical practice.

“…The miR-92a targets and downregulates estrogen receptor beta (ERβ), and is controlled by estrogen [93]. Since higher levels of estrogen were found in shift workers [94][95][96][97], miR-92a may contribute to the deregulation of estrogen levels induced by shift work. Hence, it would be interesting to perform additional investigations regarding the possible role of miR-92a related to a higher risk of breast cancer in shift workers.…”

Exosomal miR-92a Concentration in the Serum of Shift Workers

Shift work is associated with alterations in the human biological clock and metabolism. Serum exosomal miR-92a concentration was inversely correlated with brown adipose tissue activity playing a pivotal role in energy balance. In this study, miR-92a was measured in serum exosomes of 30 workers engaged in shift and daytime work. No significant metabolic alterations were shown between daytime and shift workers while a difference in serum exosomal miR-92a levels was found between the two groups. The lower levels of miR-92a in shift workers were suggestive of a higher brown adipose tissue activity compared with daytime workers. However, the possibility that other physiological and pathological processes may influence miR-92a cannot be ruled out. Our results suggest further investigations on brown adipose tissue activity and on miR-92a regulatory mechanisms, such as those related to the estrogen pathway, in shift workers.
