Infant sleep interventions with sleep measurements using actigraphy: A systematic review

AIM

This review investigated the outcomes and methodological quality of infant sleep intervention studies utilizing actigraphy.

BACKGROUND

Parents need appropriate support for infant sleep from nurses. There are few methodological reports of actigraphy in infant sleep intervention studies that objectively measure infant sleep in a natural setting.

DESIGN

This was a systematic review study.

DATA SOURCES

Ovid MEDLINE, Embase, Cochrane, CINAHL and PsycINFO were searched from database establishment to 30 December 2021.

REVIEW METHODS

This systematic review utilized the Cochrane Collaboration review guidelines.

RESULTS

Eleven sleep intervention studies were reviewed. Three used extinction-based behavioural interventions, and eight included parental education programs. The infant sleep interventions positively affected the sleep outcomes of both infants and parents. Fairly consistent effects were found on infants' number of awakenings and sleep onset latency. However, parental psychosocial outcomes were inconsistent. All studies reported device placement, the algorithm for analysis, the use of a sleep diary and number of days/nights, but external movements affecting infants' sleep records were insufficiently reported. Only two studies had a low risk of bias.

CONCLUSIONS

The infant sleep interventions had positive effects on both infants and their parents. Comprehensive methodological considerations are required for more standardized assessments using actigraphy for infant sleep evaluation.

Exploring the potential use of the metaverse in nurse education through a mock trial

BACKGROUND

The metaverse has been attracting attention as a space for the application of education, where integrating the real and virtual worlds offers immersive 3D experiences. Consequently, its potential for higher education, including nursing, is being explored as a dynamic alternative to traditional education.

OBJECTIVES

This study explores the applicability of metaverse in nurse education. It was conducted to implement a mock court on the metaverse platform and explore the learning experiences of nursing students through mock trials.

DESIGN

Qualitative study.

SETTINGS

A virtual mock court in VRChat (a virtual reality space).

PARTICIPANTS

Fourteen participants were divided into three groups.

METHODS

An orientation was conducted to explain the virtual space before the mock trial. On the day of the mock trial, a health survey of study participants was conducted in advance. After the mock trial, questionnaires and reflective diaries were written.

RESULTS

The experiences of nursing students were organized into eleven sub-themes and three themes: "core features of the metaverse platform," "participation in a mock trial in the VRChat virtual space," and "metaverse-based learning using a mock trial."

CONCLUSIONS

Nursing students participated and immersed themselves in learning while accepting the characteristics of the metaverse platform, which differs from face-to-face classes or existing educational methods. The metaverse enables reflective learning based on experiential learning and strengthens awareness of diverse viewpoints.

Effectiveness of a Strength-Based Intervention into Nursing Education in South Korea

Purpose

This study aimed to examine the effectiveness of strength-based interventions integrated into the nursing education.

Materials and Methods

The participants were 259 baccalaureate nursing students in South Korea. Over 15 weeks, strength-based intervention was integrated into the regular nursing curriculum. Stress, resilience, and well-being of the participants were measured before and after the intervention. The data were analyzed using a linear mixed model via the SPSS statistics 21.0. program.

Results

There was a negative weak association between stress and well-being and between stress and resilience (r = -0.164, p = 0.009 and r = -0.138, p = 0.029, respectively) and a positive moderate association between well-being and resilience (r = 0.561, p<0.001). After adjusting the covariates, the interaction of group*time for stress and resilience were significant after the intervention, reflecting a higher status of stress and improved resilience. (p= 0.046 and 0.030 respectively).

Conclusion

Integrating strength-based interventions into the nursing curriculum was effective in improving the mental health of Korean nursing students. Future research is needed to identify various ways of applying positive psychology to the nursing education.

Nursing students' self-directed learning experiences in web-based virtual simulation: A qualitative study

BACKGROUND

Since the start of the COVID-19 pandemic, virtual reality simulation, including web-based simulation, has increased in nursing education. This study explored nursing students' self-directed problem-solving in web-based virtual simulation experiences.

METHOD

Convenience sampling yielded 16 Korean senior nursing students who had experienced clinical practice in the last semester. Data were collected from August 2020 to January 2021 through in-depth Zoom video interviews and organized using NVivo version 12.0. Thematic analysis was applied to analyze the data.

RESULTS

The following four themes were identified from nursing students' learning experiences during the web-based virtual simulations: "self-awareness of a lack of nursing competency in virtual reality," "applying new learning strategies learned from failure," "voluntary learning behavior," and "cognitive shift toward a holistic understanding." Web-based virtual simulations activated various cognitive and metacognitive factors of self-directed learning, and the system's prompt feedback and students' reflections facilitated learning effects. Nursing students corrected their cognitive errors while learning from their failures and mistakes and gained a holistic view of nursing practice.

CONCLUSION

In this study, web-based self-directed learning activated the metacognition of nursing students in a virtuous cycle. The virtual environment with no actual harm to the patient has become a space for learners to experience a sense of confidence, achievement, and satisfaction. Web-based virtual simulation can be an effective teaching method to improve nursing students' self-directed learning abilities and nursing competency.

A qualitative study of the sleep ecology of infants under 2 years old and their mothers in South Korea

OBJECTIVES/DESIGN

Infancy is a crucial period for establishing an individual's sleep pattern, and it is a common period during which infants and mothers experience sleep problems. The aim of this qualitative study was to explore the sleep ecology of infants under 2 years of age and their mothers.

SETTING/PARTICIPANTS

The study participants were 20 mothers with infants aged 3-19 months living in South Korea.

METHODS

Data were collected through in-depth interviews and analyzed using the thematic analysis.

RESULTS

Five themes related to the sleep of infants and their mothers emerged from the data: (1) changes in sleep patterns, (2) room-sharing, (3) environmental factors affecting sleep, (4) efforts to improve sleep quality, and (5) infant sleep and the mother's health. The sleep patterns of infants and their mothers were mutually interrelated, and were strongly affected by various environmental factors, including infants' biological maturity (a microsystem) as well as cultural factors (a macrosystem). Culture had an especially profound effect on sleep patterns of infants, similar to the effects of microsystem-level factors.

CONCLUSIONS

To improve the sleep quality of infants and mothers, an ecological approach considering the biological characteristics and cultural contexts of infants is required based on an understanding of sleep as a phenomenon that evolves in a relationship of mutual influence between infants and mothers.

Effects of school-based "We Fit" weight control programme in adolescents

Aim

This study examined the effects of a 12‐week school‐based “We Fit” weight control programme.

Design

A nonequivalent control group was used, with a non‐synchronized pretest–posttest design.

Methods

In total, 109 Korean high school adolescents participated. The programme comprised exergaming, diet diary and counselling, health education, and social networking service‐based group discussions. Anthropometric factors, physiological factors and physical activity (daily steps and sitting time) were measured in the intervention and the control groups before and after the intervention. Programme satisfaction was assessed post‐intervention. Data were analysed using descriptive statistics; the chi‐square, Mann–Whitney U and t tests; and generalized estimating equations.

Results

The intervention group showed a significantly decreased waist circumference, increased skeletal muscle mass, increased high‐density lipoprotein cholesterol, decreased low‐density lipoprotein cholesterol and reduced weekend sitting time.

Conclusion

This study adds to the evidence for the applicability and effectiveness of healthy weight control programmes using exergames for adolescents in school settings.

Association of Weight Control Behaviors with Body Mass Index in Korean Adolescents: A Quantile Regression Approach

PURPOSE

Adolescents are interested in weight control but likely practice unhealthy weight control behaviors. This study aimed to examine weight control behaviors associated with body mass index (BMI) in Korean adolescents.

DESIGN AND METHODS

In this descriptive cross-sectional study of 16- to 19-year-old adolescents (97 girls and 90 boys), analyses were conducted of physical activity, sedentary behaviors, dietary behaviors, and self-efficacy for physical activity and diet. Daily steps were measured using pedometers. Height and weight were self-reported. We conducted descriptive statistics and quantile regression analysis using STATA 14.0.

RESULTS

About 10% were underweight, and 8.6% overweight and obese. Average weekday and weekend steps/day were <10,000. Only 4.3% reported performing moderate-to-vigorous physical activity (MVPA) daily. Less than half (42.5%) reported that they had three meals/day every day. Most (89.3%) had milk less than once/day. Quantile regression showed that, for the 5th BMI percentile group, (1) age (β = 0.941) and milk consumption (β = 2.148) were significantly positively associated with BMI, whereas (2) dietary self-efficacy (β = -0.083) was significantly negatively associated with BMI. For the 95th percentile group, having three meals/day (β = 2.558) was significantly positively associated with BMI, whereas MVPA (β = -5.440) and muscle-strengthening exercise (β = -3.392) were significantly negatively associated with BMI.

CONCLUSIONS

Milk consumption was positively associated with BMI of underweight adolescents, whereas physical activities were negatively associated with BMI of overweight and obese adolescents.

PRACTICE IMPLICATION

Weight control programs for adolescents may need to be tailored for differing BMI levels.

The anti-diabetic effects of ethanol extract from two variants of Artemisia princeps Pampanini in C57BL/KsJ-db/db mice

The anti-diabetic effects of two variants of Artemisia princeps Pampanini, sajabalssuk (SB) and sajuarissuk (SS), were investigated in type 2 diabetic animal using their ethanol extracts. Male C57BL/KsJ-db/db (db/db) mice were divided into control, SB ethanol extract (SBE), SS ethanol extract (SSE), or rosiglitazone (RG) groups and their age-matched littermates (db/+) were used. Supplementation of the SBE (0.171 g/100g diet), SSE (0.154 g/100g diet), and RG (0.005 g/100g diet) improved glucose and insulin tolerance and significantly lowered blood glycosylated hemoglobin levels, as compared to the control group. Plasma insulin, C-peptide and glucagon levels in db/db mice were higher in the db/+ mice, however these values were significantly lowered by SBE, SSE or RG-supplement. Hepatic GK activity was significantly lower in the db/db mice than in the db/+ mice, while hepatic G6Pase activity was vice versa. Supplementation of SBE, SSE and RG reversed these hepatic glucose-regulating enzyme activities. In addition, SBE and SSE markedly increased the hepatic glycogen content and muscle ratio as compared to the control group, but they did not alter the food intake, body weight and plasma leptin level. The RG group, however, showed a significant increase in the food intake, body weight and plasma leptin. These results suggest that SBE and SSE exert an anti-diabetic effect in type 2 diabetic mice.
