Using electronic devices before bedtime impacts sleep quality and has become a major public health issue. This study aims to investigate the associations between electronic devices (EDs) use before bedtime and sleep quality in Vietnamese university students. A total of 369 university students from three departments were recruited. Participants completed self-report surveys, including demographic characteristics, lifestyle, ED-use behaviors, the Pittsburgh Sleep Quality Index, and the Center for Epidemiologic Studies Depression Scale. A total of 48.8% of the students experienced poor sleep quality, and 98.1% reported using at least one type of ED every day within two hours before bedtime. Smartphones are the most used devices (92.3%). ED usage within two hours before bedtime (p = 0.031), lack of exercise (p = 0.006), alcohol consumption (p = 0.025), and coffee intake after 4 pm (p = 0.018) were associated with poor sleep quality. ED use near bedtime for a duration longer than 30 min (p = 0.001) and depression (p < 0.001) were associated with poorer sleep quality among university students. ED use near bedtime more than 30 min was significantly associated with poorer sleep quality after adjusting depression status, exercise, and caffeine/alcohol intake in the latter part of the day. This study emphasizes the importance of adequate sleep and restriction of ED use near bedtime, which are necessary for better sleep in university students.

Objective: Diabetic foot ulcers are an invasive complication of diabetes and are increasing. This study investigates the relationship between health beliefs and foot self-care behaviors, among people with type II diabetes. Methods: A cross-sectional design was adopted, and 98 patients were recruited from outpatient clinics of the endocrine department. The questionnaires of Demographic, Diabetes Foot Ulcer Health Belief Scale (Health Beliefs, DFUHBS), and Diabetes Foot Self-Care Behavior Scale (Self Care, DFSBS) were used to collect data. Results: Among the subjects living alone or who had diabetes less than ten years, the score of DFSBS was significantly lower than among those living with families or who had diabetes for ten years or more. The frequency of performing diabetes foot self-care behavior, among males was lower than among females significantly. Although there was no significant difference in the Health Belief total score, there were differences in the benefit subscale. Those who had junior high school level or less or had diabetes less than ten years, their score was significantly lower than those with senior high school level or more or had diabetes ten years or more. In a multivariable regression model, living with family, diabetes duration, and health beliefs explained 42.9% of the variance of diabetic-foot self-care behaviors. Conclusions: Living alone, shorter duration of diabetes, male gender, and lower health belief scores predict less adequate diabetic foot self-care behavior. Health care providers should assess these factors when designing individual care plans.

To respond to patients’ increasing demands and strengthen nursing professionals’ capabilities, nursing students are expected to develop problem-solving skills before they enter the workforce. Problem-based learning (PBL) is expected to provide effective simulation scenarios and realistic clinical conditions to help students achieve those learning goals. This article aims to explore the effects of PBL strategies on nursing students’ self-evaluation of core competencies. This longitudinal cohort survey study evaluated 322 nursing students attending Chung Shan Medical University, Taiwan, in 2013 and 2014, where PBL teaching strategies are used in all four undergraduate years from freshman to senior. Based on their undergraduate academic levels, students were categorized into three groups- one-year PBL exposure, two-year PBL exposure, and three-year exposure. A core competency questionnaire was administered twice to ask participants to self-assess five professional competencies: learning attitude, problem identification, information analysis, execution, and life-long learning. The results showed that students with the longest exposure to PBL (Group 3) had higher self-evaluated scores for all core competencies than the other groups, except for the execution competency. The mean total competency score increased by 0.12 points between the pre-and-test. In addition, the mean score increased significantly more in Group 3 than in Groups 1 and 2. These trends were consistent for the information analysis, execution, and life-long learning competencies. In conclusion, the changes in the self-evaluated scores between groups indicate PBL strategies effectively improve nursing students’ core competencies. The longest exposure group reported higher self-evaluated core competency scores than the other groups, especially for the information analysis, execution, and life-long learning competencies.

Objective: Breast cancer is the most common cancer among women in Taiwan. However, the discomfort of receiving mammograms reduces the willingness to screen. Materials and methods This study using a quasi-experimental design and recruited 150 participants in a medical center, Taiwan. In the control group, only provided traditional health education sheets, the experimental group has joined the intervention of multimedia health education. State-Trait Anxiety Inventory and Visual Analogue Scale, respectively, were used to compare the differences in anxiety and pain between the two groups before and after receiving mammography. Results: After the intervention, the experimental group's state anxiety score was significantly lower than that of the control group (30.63 ± 8.43 vs. 33.77 ± 10.74, p < .05). However, there was no significant difference in pain scores (4.13 ± 2.37 vs. 4.57 ± 2.31; p = .25). Conclusions: Younger, prior experience with mammography, and high trait anxiety affect pain and state anxiety of women undergoing mammography. The multimedia health education intervention could reduce anxiety effectively, but it does not significantly relieve the pain undergoing mammography.
