BackgroundVideo feedback has been shown to be an effective teaching tool that can improve student learning when having them view their own performance. However, the literature on the effect of integrating smartphones with video feedback in fundamental nursing skills teaching is sparse. ObjectiveThis study aimed to explore the potential effects of video feedback through smartphone-based instant messaging on teaching undergraduate nursing students fundamental nursing skills. MethodsWe conducted a study on teaching fundamental nursing skills to 6 classes of second-year undergraduate nursing students. In 2 classes (the intervention group), the instructor elected to use smartphone-based video feedback to facilitate teaching; instructors in the other 4 classes (the control group) elected to use routine methods of teaching without video feedback. Scores from the final examination, in-class assignments, and the General Self-Efficacy Scale questionnaire were collected and compared between the two groups. Multiple linear regression analysis was performed to estimate the independent effect of video feedback after adjusting for gender, age, and prior experience in the use of WeChat/QQ in learning applications. An ad hoc questionnaire was used for student evaluation of the novel smartphone-based video feedback teaching method. ResultsA total of 195 nursing students (65 in the video feedback group and 130 in the control group) completed the study and were included in the final analysis. Mean and standard deviation of scores on the final examination, bed making, aseptic procedure, vital signs measurement, and oxygen therapy were 91.29 (SD 2.36), 90.52 (SD 3.18), 93.23 (SD 3.16), 91.65 (SD 4.21), and 92.06 (SD 3.58), respectively, in the video feedback group and 89.99 (SD 3.12), 81.71 (SD 8.63), 87.12 (SD 5.50), 87.45 (SD 8.00), and 90.37 (SD 6.36), respectively, in the control group (differences were statistically significant). The mean and standard deviation of scores for assignments in catheterization and enema and General Self-Efficacy Scale were 89.69 (SD 3.22), 91.14 (SD 3.15), and 24.52 (SD 5.35), respectively, in the video feedback group and 88.82 (SD 7.48), 90.79 (SD 6.08), and 24.50 (SD 6.16), respectively, in the control group (differences were not statistically significant). The majority (over 98%) of nursing students were satisfied with this smartphone-based video feedback teaching method. ConclusionsVideo feedback through smartphone-based instant messaging may be an effective way to improve nursing students’ academic performance and professional skills.

BackgroundIn recent years, attempts have been made to use mobile phone text messaging (short message service, SMS) to achieve positive results for a range of health issues. Reports on the impact of maternal education programs based on this widely available, inexpensive, and instant communication tool are sparse. ObjectiveThis study aimed to explore the impact of a maternal education program through text messaging. MethodsWe conducted a cluster randomized trial in a remote region in the Chinese province of Hunan between October 1, 2011, and December 31, 2012. We used county as the unit of randomization (a total of 10 counties), with half of the counties randomly allocated to the intervention arm (with maternal education material adapted from the World Health Organization being delivered by text messaging to village health workers and pregnant women alike) and the other half to the control arm (normal care without text messaging). Data on maternal and infant health outcomes and health behaviors were collected and compared between the 2 arms, with maternal and perinatal mortality as the primary outcomes. ResultsA total of 13,937 pregnant women completed the follow-up and were included in the final analysis. Among them, 6771 were allocated to the intervention arm and 6966 were allocated to the control arm. At the county level, the mean (SD) of maternal mortality and perinatal mortality rate were 0.0% (0.1) and 1.3% (0.6), respectively, in the intervention arm and 0.1% (0.2) and 1.5% (0.4), respectively, in the control arm. However, these differences were not statistically significant. At the individual level, there were 3 maternal deaths (0.04%) and 84 perinatal deaths (1.24%) in the intervention arm and 6 maternal deaths (0.09%) and 101 perinatal deaths (1.45%) in the control arm. However, the differences were again not statistically significant. ConclusionsAdequate resources should be secured to launch large-scale cluster randomized trials with smaller cluster units and more intensive implementation to confirm the benefits of the text messaging–based maternal education program suggested by this trial.

Vaginal lactobacilli are key regulators of host inflammation, yet the mechanisms remain understudied. In this issue of Cell Host & Microbe , Glick et al. identify a family of beta-carbolines as anti-inflammatory effectors produced by vaginal Lactobacillus species, highlighting their potential as therapeutics for vaginal inflammatory disorders.

The role of fatty acids in shaping vaginal microbiota remains unclear. In an issue of Cell , Zhu et al. use genomic and transcriptomic analyses to reveal that oleic acid (OA) selectively inhibits L. iners while promoting L. crispatus , suggesting new strategies for the treatment of bacterial vaginosis (BV).

Background and Aims: Research on the association between activity levels and sedentary behaviour with frailty in patients affected by hepatitis B cirrhosis is sparse. This study aimed to explore the association of frailty with activity levels and sedentary behaviours in patients with hepatitis B cirrhosis. Design: This cross‐sectional study followed the STROBE checklist. Methods: This study was conducted in Guangzhou, China, between August 2021 and October 2022. The frailty condition of patients with hepatitis B cirrhosis was assessed using the liver frailty index (LFI). Their physical activity levels and sedentary time were assessed using the International Questionnaire of Physical Activity. Pearson correlation and binary logistic regression were used to analyse the data. Results: Among the 503 patients with hepatitis B cirrhosis in the final analysis, 107 (21.3%) were identified as frail. Frailty was negatively correlated with walking time (r = −0.174, p < 0.001), moderate‐intensity activity time (r = −0.185, p < 0.001), high‐intensity activity time (r = −0.243, p < 0.001) and total activity time (r = −0.256, p < 0.001). Patients with insufficient activity (<150 min/week) and sedentary behaviour (≥420 min/day) were found to have 2.829 times higher risk of frailty than those with sufficient activity (≥150 min/week) and no sedentary behaviour (<420 min/day) (95% CI: 1.380, 5.799). Conclusion: Patients with hepatitis B cirrhosis who exhibited frailty demonstrated limited physical activity and engaged in sedentary behaviours. No patient or public contribution: Patients with hepatitis B cirrhosis contributed their data to the study. [ABSTRACT FROM AUTHOR]

Grade 4 peripheral intravenous infiltration with skin tears has seldom been reported. On 4 August 2020, a 35‐year‐old female patient was admitted to the emergency department of our hospital because of postprandial abdominal pain for 2 hours. She was diagnosed with a severe acute pancreatitis with type II diabetes mellitus. On 7 August, a vein detained needle was inserted into the dorsal vein of her right foot to infuse drugs. On 9 August, a grade 4 infiltration, discoloured and bruised skin with a swollen area of 11 cm × 9 cm around the infusion part of her right foot, was discovered. The infusion was stopped immediately and the residual drug was aspirated at the infusion site. When removing the vein detained needle, the skin surrounding the infusion site on the right foot was torn by the adhesive dressing. The size of the skin tears was 6 cm × 3 cm (type 3). The patient was provided with appropriate dressing, manual lymphatic drainage, and surgical intervention. Two months later, she was fully recovered with no functional impairment of the affected foot. Timely local wound interventions could lead to a satisfactory outcome for severe peripheral intravenous infiltration with skin tears. [ABSTRACT FROM AUTHOR]
