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.

Maintaining good oral hygiene is essential for preventing and managing oral health problems. This systematic review aimed to identify and assess clinical practice guidelines on oral hygiene, focusing on quality and key areas. A comprehensive search was conducted in PubMed, CINAHL, Scopus, Cochrane, and organizational websites. Guidelines from health organizations that focused on oral health, hygiene education, and disease prevention were included. Guidelines based on expert opinions and those focusing on specific pathologies were excluded. The AGREE II tool was used to evaluate quality, and a narrative synthesis summarized recommendations across pediatric, adult, and senior age groups. Nine studies were reviewed. Results showed that electric toothbrushes do not significantly outperform manual ones in preventing cavities, though they may reduce plaque. Fluoride toothpaste is less effective if followed by rinsing with water. For adults, mouthwashes with chlorhexidine or sodium fluoride are recommended. Checkups every six months are advised for healthy children and adults. Proper denture care is also emphasized. Regular updates to oral care guidelines are necessary, as oral health affects essential functions and social well‐being.

Greater evaluations are needed to identify barriers or facilitators in nurses' guidelines adherence. The current review aims to explore extrinsic and intrinsic factors impacting nurses' compliance. Mixed-method systematic review with a convergent approach, following the PRISMA checklist and the JBI Mixed Methods Review Methodological Guidance was conducted. MEDLINE, Embase, CINAHL were systematically searched, to find studies published between 2010 and 2021, including qualitative, quantitative or mixed-methods articles. Sixty studies were included, and the major findings were analysed by aggregating them in two main themes: intrinsic and extrinsic factors. The intrinsic factors were: a) knowledge and skills; b) attitudes of health personnel; c) sense of belonging towards guidelines. The extrinsic factors were: a) organizational and environmental factors; b) workload; c) guidelines structure; d) patients and caregivers' attitude. The included studies report lack of resources, among environmental factors, as the main barrier perceived. Nurses, who are at the forefront in addressing the direct application of knowledge and skills to ensure patient safety, have a higher perception of this kind of barriers than other healthcare personnel. Potential facilitators emerged in the review are positive feedback and reinforcements at the workplace, either from the members of the team or from the leaders. Moreover, the level of active participation of the patient and caregiver could have a positive impact on nurses' guidelines adherence. Guidelines implementation remains a complex process, resulting in a strong recommendation to support health policymakers and nursing leaders in implementing continuing education programs.

Background: The Fundamentals of Care framework emphasizes a patient-centered approach that prioritizes the nurse–patient relationship and care environment to meet patients’ basic needs, including oral hygiene. Recognized as crucial for preventing systemic health problems, oral care neglect is a global concern. Studies identify missed oral care as a widespread issue, contributing to significant patient safety risks. This study aimed at measuring missed nursing care occurrence in a Northern Italian university hospital, exploring the association between missed oral care with nursing staff characteristics and oral care policies. Methods: A single-center cross-sectional study was conducted according to the STROBE guidelines. Data collection was performed in May 2022 using the MISSCARE survey, a self-administered questionnaire sent by email to 473 nurses from all inpatient units. The degree of implementation of oral care policies was obtained by accessing the Facility Score Sheet data at the department level. Descriptive statistics, chi-square tests, and Fisher tests were conducted using SAS 9.4 and R software. Results: Providing oral care was the third-most missed nursing care after rotating patients every two hours and walking them three times daily. The reasons for missed care included resource shortage and high patient turnover. The Facility Score Sheet data showed a low adoption of oral care policies. No significant associations were found between missed oral care and both nurses’ characteristics and oral care policy at the department level. Conclusions: The study confirms highly missed oral care in acute care settings, emphasizing the urgent need for systemic changes via an evidence-based oral care policy and practice implementation. This study was prospectively registered under protocol 293 CE 050/2022 (8 Aril 2022).
