Chronotype, nursing activity, and gender: A systematic review.

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.

Takotsubo syndrome and dialysis: an uncommon association?

This review was performed to investigate the association between treatment with dialysis and Takotsubo syndrome in patients with end-stage renal disease. We systematically explored the PubMed database using the search terms "Takotsubo cardiomyopathy" and/or "stress-induced cardiomyopathy" and/or "Takotsubo syndrome" in combination with "dialysis" and "uremia." Of 3630 articles found, 8 articles reporting 10 cases were selected for analysis. Most patients were women, and their age ranged from 51 to 84 years. Diabetes mellitus and hypertension were diagnosed in 40% of patients, and glomerular disease was diagnosed in 30%. One only patient was treated with peritoneal dialysis; all others were treated with hemodialysis. The outcome was unfavorable in only one patient. An association between Takotsubo syndrome and dialysis is uncommon, but not negligible, and comorbidities play a major role in determining the clinical outcome.

Reducing the risk of venous thromboembolism using apixaban - patient perspectives and considerations. Should more attention be given to females?

BACKGROUND: New oral anticoagulant agents, such as apixaban, rivaroxaban, dabigatran, or endoxaban, have recently become for patients an alternative option to conventional treatment in the therapy of venous thromboembolism (VTE). Thus, we aimed to review the available information on adverse events (AEs) of apixaban compared to conventional therapy (heparin or vitamin K antagonists) in randomized controlled trials (RCTs) on patients treated for VTE, with a particular attention to sex subgroups. METHODS: An electronic search in MEDLINE and Embase was performed by using the keywords "apixaban" and "venous thromboembolism". All RCTs focused on apixaban in the treatment and prevention of VTE were evaluated for the presence of AEs. AEs were classified as serious, bleeding, and cause of discontinuation. Moreover, we also searched by using the keywords "gender" and "venous thromboembolism" and "anticoagulants". RESULTS: Considering all subjects enrolled in the eleven RCTs as a whole to investigate the occurrence of AEs, we extrapolated an events/subjects rate of 57.8% for AEs (6,445/11,144), 7.7% for serious AEs (975/12,647), 9.1% for bleeding events (1,229/13,454), and 3.2% for discontinuation of apixaban (421/13,039). The percentage of AEs was lower in subjects treated with apixaban than in those treated with conventional VTE therapy (53% vs 56.3%, respectively). However, only one study provided data on separate analysis by sex of either efficacy or safety of apixaban. CONCLUSION: Under the patient's perspective, apixaban could represent a good choice in the treatment of VTE, due to its pharmacological, economical, and safety profile. These positive aspects are certainly present in both sexes, since the available studies include a correct percentage of women, but data with separate analyses by sex are extremely limited. Future clinical trials should include in their results on clinical impact and outcomes a stratification by sex, and studies aimed to evaluate possible sex-related differences for these drugs should be strongly encouraged.

Chronotype, gender and general health.

BACKGROUND: Light-dark alternation has always been the strongest external circadian "zeitgeber" for humans. Due to its growing technological preference, our society is quickly transforming toward a progressive "eveningness" (E), with consequences on personal circadian preference (chronotype), depending on gender as well. The aim of this study was to review the available evidence of possible relationships between chronotype and gender, with relevance on disturbances that could negatively impact general health, including daily life aspects. METHODS: Electronic searches of the published literature were performed in the databases MEDLINE and Web of Science, by using the Medical Subject Heading (MeSH), when available, or other specific keywords. RESULTS: Results were grouped into four general areas, i.e. (a) "General and Cardiovascular Issues", (b) "Psychological and Psychopathological Issues", (c) "Sleep and Sleep-Related Issues" and (d) "School and School-Related Issues". (a) E is associated with unhealthy and dietary habits, smoking and alcohol drinking (in younger subjects) and, in adults, with diabetes and metabolic syndrome; (b) E is associated with impulsivity and anger, depression, anxiety disorders and nightmares (especially in women), risk taking behavior, use of alcohol, coffee and stimulants, psychopathology and personality traits; (c) E has been associated, especially in young subjects, with later bedtime and wake-up time, irregular sleep-wake schedule, subjective poor sleep, school performance and motivation, health-related quality of life; (d) E was associated with lowest mood and lower overall grade point average (especially for women). CONCLUSIONS: Eveningness may impact general health, either physical or mental, sleep, school results and achievements, especially in younger age and in women. The role of family support is crucial, and parents should be deeply informed that abuse of technological devices during night hours may lead to the immature adjustment function of children's endogenous circadian pacemakers.
