  • Background: The abdominal drawing-in maneuver (ADIM), a method of lumbar stabilization training, is an effective neuromuscular intervention for lumbar instability associated with low back pain (LBP). Objects: The purpose of this study was to compare the effect of a 2-week period of the ADIM and tensor fasciae latae-iliotibial band (TFL-ITB) self-stretching on lumbopelvic rotation angle, lumbopelvic rotation movement onset, TFL-ITB length, and pain intensity during active prone hip lateral rotation. Methods: Twenty-two subjects with lumbar extension rotation syndrome accompanying shortened TFL-ITB (16 males and 6 females) were recruited for this study. The subjects were instructed how to perform ADIM training or ADIM training plus TFL-ITB self-stretching program at home for a 2-week period. A 3-dimensional ultrasonic motion analysis system was used to measure the lumbopelvic rotation angle and lumbopelvic rotation movement onset. An independent t-test was used to determine between-group differences for each outcome measure (lumbopelvic rotation angle, lumbopelvic rotation movement onset, TFL-ITB length, and pain intensity). Results: The results showed that ADIM training plus TFL-ITB self-stretching decreased the lumbopelvic rotation angle, delayed the lumbopelvic rotation movement onset, and elongated the TFL-ITB significantly more than did ADIM training alone. Pain intensity was lower in the ADIM training plus TFL-ITB self-stretching group than the ADIM training alone group; however, the difference was not significant. Conclusion: ADIM training plus TFL-ITB self-stretching performed for a 2-week period at home may be an effective treatment for modifying lumbopelvic motion and reducing LBP.

  • Purpose: Globally, 25 million children were either unvaccinated or under-vaccinated in year 2021. Among them, India had the highest number of children unvaccinated. Studies have shown impact of coronavirus disease 2019 (COVID-19) pandemic on routine health-care services. Present study aimed to estimate the impact of COVID-19 on utilization of routine immunization services during years 2020 and 2021 in tertiary-care facility. Materials and Methods: Record based descriptive analytic study was conducted at pediatric tertiary-care hospital, Jaipur. Data of children vaccinated as per the National Immunization Schedule for the period January 2019 to December 2021 were retrieved from the immunization records. Doses administered were assessed as a proxy measure of vaccine coverage. The vaccination trends of 2020 and 2021 were compared assuming base year 2019. Unpaired t-test of significance and Pearson correlation was used for correlation analysis. Results: There was significant drop in the vaccine counts after emergence of COVID-19 pandemic. In year 2020 and 2021, mean monthly vaccine count was 2,190±715.1 and 2,305±393.2, respectively, in which maximum drop was in April 2020 (-79.12%) and May 2021 (-57.16%) when it was compared with matched month of base year. There was negative correlation between percent change in vaccine count and COVID-19 cases in 2020 (r=-0.057, p=0.861) and 2021 (r=-0.827, p=0.001) as compared to year 2019. Conclusion: Study concludes that there was a significant gap in utilization of routine immunization services during the COVID-19 pandemic. This necessitates planning and management of routine immunization services in-case of future pandemics to avoid resurgence of vaccine-preventable diseases in the Rajasthan.

  • Objective: Little is known about the effects of using different expert-determined reference standards when evaluating the performance of deep learning-based automatic detection (DLAD) models and their added value to radiologists. We assessed the concordance of expert-determined standards with a clinical gold standard (herein, pathological confirmation) and the effects of different expert-determined reference standards on the estimates of radiologists' diagnostic performance to detect malignant pulmonary nodules on chest radiographs with and without the assistance of a DLAD model. Materials and Methods: This study included chest radiographs from 50 patients with pathologically proven lung cancer and 50 controls. Five expert-determined standards were constructed using the interpretations of 10 experts: individual judgment by the most experienced expert, majority vote, consensus judgments of two and three experts, and a latent class analysis (LCA) model. In separate reader tests, additional 10 radiologists independently interpreted the radiographs and then assisted with the DLAD model. Their diagnostic performance was estimated using the clinical gold standard and various expert-determined standards as the reference standard, and the results were compared using the t test with Bonferroni correction. Results: The LCA model (sensitivity, 72.6%; specificity, 100%) was most similar to the clinical gold standard. When expert-determined standards were used, the sensitivities of radiologists and DLAD model alone were overestimated, and their specificities were underestimated (all p-values < 0.05). DLAD assistance diminished the overestimation of sensitivity but exaggerated the underestimation of specificity (all p-values < 0.001). The DLAD model improved sensitivity and specificity to a greater extent when using the clinical gold standard than when using the expert-determined standards (all p-values < 0.001), except for sensitivity with the LCA model (p = 0.094). Conclusion: The LCA model was most similar to the clinical gold standard for malignant pulmonary nodule detection on chest radiographs. Expert-determined standards caused bias in measuring the diagnostic performance of the artificial intelligence model.

  • Purpose: Foot alignment affects the overall balance and alignment of the body. This study examined the relationship between the foot parameters and scoliosis in children and adolescents through simple radiographs. Materials and Methods: Two hundred and forty-one outpatients under 15 years old from 2013 to 2022 were evaluated. Patients with an abnormal leg length discrepancy or pelvic tilt were screened. The patients included were divided into four groups. Each group was tested to determine if they had scoliosis. The foot anterior-posterior/lateral X-rays were selected for the foot parameters, and the EOS system was used for the spline and pelvis parameters. Results: A t-test of all groups showed no statistically significant difference as the p-value exceeded 0.05. An analysis of variance (ANOVA) comparing the Cobb's angle and foot parameters did not show a significant correlation. On the other hand, female and older patients had a higher Cobb's angle. Conclusion: No direct relationship was noted between scoliosis and the foot parameters that could be measured radiographically among children and adolescents. In addition, no correction between the Cobb's angle and foot parameters was found.

  • Purpose: This study aimed to investigate the influence of public hospital nurses' psychological capital and nursing work environment on job embeddedness. Methods: A descriptive cross-sectional survey was conducted from October 21 to 31, 2022. A total of 200 participants working at a public hospital in Gyeonggi-do were recruited. Data collection was conducted using questionnaires. Data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical regression analysis. Results: The mean scores of psychological capital and nursing work environment were 3.32±0.60 out of 5 and 2.43±0.48 out of 4, respectively. The mean score for Job embeddedness was 3.14±0.72 out of 5. Psychological capital showed a significant positive correlation with nursing work environment and job embeddeness, and nursing work environment also showed a significant positive correlation with job embeddedness. The factors affecting job embeddeness of public hospital nurses were positive psychological capital, nursing work environment, and age. Conclusions: The results of this study suggest that in order to increase job embeddedness, it is necessary to develop education and programs that can strengthen positive psychological capital of public hospital nurses. In addition, the nursing work environment must be improved by providing appropriate manpower and resources.

  • Purpose: Nurses have been reported to be at an increased risk for miscarriage and preterm labor. However, there is limited knowledge regarding nurses' preconception health behaviors. Therefore, this study aimed to identify factors influencing these behaviors. Methods: One hundred sixty nurses, who were planning their first pregnancy within the upcoming year, participated in an online survey from August 11 to October 31, 2021. Data on preconception health behavior, perceived health status, pregnancy anxiety, nursing practice environment, and social support were analyzed using the t-test, Pearson correlation coefficients, and multiple regression analysis. Results: Age (p=.024), educational level (p=.010), marital status (p=.003), work experience (p=.003), satisfaction with the work department (p<.001), smoking status (p=. 039), and previous health problems related to pregnancy outcomes (p=.004) were significantly associated with nurses' preconception health behaviors. Furthermore, perceived health status (p<.001), pregnancy anxiety (p=.011), nursing practice environment (p=.003), and social support (p<.001) showed significant correlations with preconception health behaviors. Social support (β=. 28, p=.001), satisfaction with the work department (β=.23, p=.032), marital status (β=.22, p=.002), and perceived health status (β=.23, p=.002) were confirmed as factors associated with preconception health behaviors. These factors explained 40.9% of the variance in preconception health behaviors (F=6.64, p<.001). Conclusion: Clinical nurses' preconception health behaviors were influenced by social support, perceived health status, satisfaction with the work department, and marital status. Interventions to improve clinical nurses' preconception health behaviors should target social support and perceived health status. A preconception health behavior education program considering clinical nurses' marital status and satisfaction with the workplace can also be implemented.

  • Purpose: This descriptive survey study aimed to examine the effects of grit, social support, job crafting, and evidence-based practice competency on job satisfaction among nurses. Methods: The participants of this study were 211 clinical nurses with experience of more than six months. Data were collected using through an online survey from February 1 to February 17, 2023. The questionnaires was consisted of general characteristics, grit, social support, job crafting, evidence-based practice competency, and job satisfaction. Data were analyzed using descriptive statistics(frequency, percentage, mean, and standard deviation), t-test, ANOVA, Pearson correlation coefficient, and multiple regression analysis with the SPSS/WIN 28.0 program. Results: The average scores of the main variables were 3.08±0.44 out of four for grits, 3.67±0.52 out of five for social support, 4.20±0.64 out of five for job crafting, 4.84±0.71 out of seven for evidence-based practice competency, and 3.72±0.55 out of five for job satisfaction. In the regression model, the factors affecting the nurses' job satisfaction were grit (β=0.66, p<.001) and social support (β=0.11, p=.046), which explained 78.7% of the variance in job satisfaction. Job crafting and evidence-based practice competency were correlated with job satisfaction; however, there was no statistically significant effects of these variables on job satisfaction. Conclusion: Based on the findings of this study, grit and social support showed the most significant effects on the job satisfaction of nurses. Therefore, active support is needed to develop a strategy to improve nurses' grit and to create a supportive work environment, which would be helpful to increase their job satisfaction.

  • Purpose: This descriptive research study is intended to develop practical strategies for enhancing the quality of elderly care by evaluating the levels of ageism and compassion competence among clinical nurses and their impact on geriatric nursing performance. Methods: This study involved 162 nurses who provided direct care to elderly patients in a department with many such patients. Of the 161 returned questionnaires, 150 were analyzed, excluding 11 that had insincere or missing responses. To analyze the data, a comprehensive approach was employed using the IBM SPSS 27.0 program that included calculations of frequency and percentage, mean, and standard deviation, as well as more complex statistical tests such as the independent t-test, one-way ANOVA, Pearson's correlation coefficients, and hierarchical linear regression analysis. Results: Compassion competence was significantly positively correlated with elderly care and negatively correlated with ageism. This study conclusively demonstrates that compassion competence among nurses in geriatric nursing situations plays a crucial role in provision of quality nursing grounded in understanding and respect for the elderly. Consequently, it is imperative to develop educational strategies tailored to each career stage of nursing practice to further enhance effective elderly care. Conclusion: This study conclusively demonstrates that compassion competence in geriatric nursing situations plays a crucial role in provision of quality nursing grounded in understanding and respect for the elderly. Consequently, it is imperative to develop educational strategies tailored to each career stage of nursing practice to further enhance effective elderly care.
