ABSTRACT

INTRODUCTION: Employees are placed in various job rotations between two or more tasks or vocations at regular intervals to ensure that they are exposed to all elements of the company. Job rotation is a methodical approach that permits employees to avoid boredom while also allowing them to develop and grow. Both management and personnel objectives are met with this strategy. It aids in the identification of employee potential and abilities. Through job rotation, employees are exposed to all aspects of the company. Employee abilities and competencies are evaluated ahead of time to ensure that the employee is deployed in the best possible position. However, it does permit the pursuit of personal interests while gaining practical knowledge in a variety of industries or processes. The present study was undertaken with an aim to assess the effect of job rotation on the nursing staff in a private hospital of Vadodara.

METHODOLOGY: The study was cross-sectional in nature where the perception of the nursing staff was gathered through a structured questionnaire. The questionnaire assessed the perception of the staff on a five point likert scale from strongly agree to strongly disagree. The sample size of the study was 126. Mann Whitney Test and Kruskal Wallis test was used to assess the effect of job rotation with respect to gender and age, years of experience respectively. The statistical analysis was undertaken at 95% confidence level with statistical significance at a p value of less than 0.05.

RESULTS: The results depicted that there was no difference in the perception towards effect of job rotation with respect to gender and age group. However, with respect to job rotation not interrupting the employees’ work life and no effect on personal life, there was statistical significant difference with respect to the years of experience of the nursing staff as the p value was less than 0.05.

CONCLUSION: Job rotation, in their opinion, causes frequent interruptions in both the job and personal life of those who participate in it. The nurses working in the hospital came up with appropriate job rotation ideas that took into consideration their age and years of experience. It appears that most of the criteria indicate that the nursing staff members were satisfied with their job rotation, which lends support to the findings of the study.

ABSTRACT

INTRODUCTION: Burnout is often misconstrued for stress, whereas it is one of the consequences of stress when not managed prosperously. Stress leads to apprehensiveness, loss of energy, and the primary damage is physical. Whereas, burnout is characterized by disengagement where emotions are blunted thus fostering helplessness and hopelessness leading to detachment and despondence, loss of motivation and ideals with the primary damage being emotional.

OBJECTIVES: To find out the prevalence and severity of stress and burnout among bank officers in Meerut District and to find the correlation between the two parameters.

METHODS: Banks were selected by simple random sampling through computer random table method for our study. Further, officer grade bank employees were approached for data collection. A prevalidated seven-point Likert scale Shriom-Melamed Burnout Questionnaire was used for the assessment of burnout. Data were analyzed using appropriate statistical tests by EPI Info and Microsoft Excel 2013.

RESULT: 19.7% bank officers have pathological burnout followed by 55.1% of bank officers who are at the brink of developing burnout. Severe stress was found only among 7.9% bank officers, whereas burnout was present in 19.4%. A positive correlation was found between stress and burnout.

CONCLUSION: It was found that stress and job burnout are linked but do not entirely overlap, with individuals having a high risk of job burnout experiencing only moderate stress. Therefore, perceived stress cannot be taken as the only indicator of risk of burnout.

ABSTRACT

BACKGROUND: Dyslipidemia, insulin resistance, hypertension, and abdominal obesity are important determinants of metabolic syndrome (MetS). Ample studies provide statistical data on the prevalence of MetS among the general public. Conversely, there is a paucity of data on the risk of MetS among different sedentary occupational groups.

OBJECTIVE: To assess the risk of MetS among female school teachers and to identify factors contributing to MetS.

METHODOLOGY: The study was conducted among 256 female school teachers residing in Chennai city. A questionnaire was used to elicit information on the socio-demographic profile, diet pattern, physical fitness, and genetic history of lifestyle diseases. Anthropometric, biochemical, and clinical parameters were measured using standard methods. MetS was diagnosed using the harmonizing definition. Data analysis was done using Statistical Package for Social Sciences software.

RESULTS: Results evince that 39.45% of female school teachers were diagnosed with MetS, of which 26.56% had three components, 9.77% had four components, and 3.12% had all components of MetS. Abdominal obesity (99%) and low levels of high-density lipoprotein cholesterol (HDL-C) (96.04%) were the most predominant components. The least common component was diastolic hypertension (32.67%). MetS components were high among school teachers aged 36-45 years and 46-55 years. Age, fasting hyperglycemia, paternal history of hypertension, physical inactivity, eating out, and consumption of refined cereals significantly contributed to MetS (P < 0.05).

CONCLUSION: Results highlight the need to identify high-risk individuals and promote a healthy lifestyle through various intervention programs.

ABSTRACT

Women in sea food processing units were involved in pre processing, grading, cleaning, freezing and packaging and they adopted static and awkward posture which results in low back pain. The aim of the present study is to analyze the factors that contribute to low back pain among women workers. A total of 244 women workers participated in the study. Socio economic background and frequency of musculoskeletal discomforts were studied. Descriptive statistics, chi square analysis and factor analysis were carried out to identify the factors contributing to low back pain. Women were involved in peeling (48.8%), setting (26.6%) and grading (24.6%) activity. Factor analysis indicated that work environment contributed to 33%, personal factors contributed to19%, work organization contributed to 16% and socio economic factors contributed to 11% for the low back pain. Worker education and periodical health surveillance will help to minimize the risk of low back pain among the women in industrial settings.

ABSTRACT

PURPOSE: Harsh parenting is positively correlated with adolescents’ smartphone addiction, according to a growing corpus of studies. The various mediating processes that could underlie this link, however, are not well understood. Based upon the experiential avoidance model, the current research aimed to identify the relation between harsh parenting and adolescents’ smartphone addiction and the mediating roles of adolescents’ depression and experiential avoidance.

METHODS: We recruited 456 adolescents (female = 52.6%; M_age = 13.19 years, SD = 0.85) at a public junior high school in China to complete the harsh discipline scale, 90-item Hopkins symptom checklist, acceptance and action questionnaire version II, and smartphone addiction scale short version. SPSS24.0 was used to conduct independent samples t-test, descriptive statistics, Pearson correlation analysis and common method bias test, PROCESS were used to conduct a significance test of the chain mediation effect on the data. Age, gender, and grade were used as con-founders that were controlled in order to make cautious predictions.

RESULTS: The results showed that (1) harsh parenting was positively correlated with adolescents’ depression, experiential avoidance, and smartphone addiction; (2) both depression and experiential avoidance fully mediated the link between harsh parenting and smartphone addiction; and (3) depression and experiential avoidance also sequentially mediated the link between harsh parenting and smartphone addiction. These findings have significant implications for the prevention and intervention of adolescents’ smartphone addiction.

CONCLUSION: These findings suggested that harsh parenting may have an indirect impact on smartphone addiction in both a simple way (parallel mediation) and a complicated way (serial mediation). In addition, these studies shed light on smartphone addiction prevention and intervention.

ABSTRACT

Current theories of attention differentiate exogenous from endogenous orienting of visuospatial attention. While both forms of attention orienting engage different functional systems, endogenous and exogenous attention are thought to share resources, as shown by empirical evidence of their functional interactions. The present study aims to uncover the neurobiological basis of how salient events that drive exogenous attention disrupts endogenous attention processes. We hypothesize that interference from exogenous attention over endogenous attention involves alpha-band activity, a neural marker of visuospatial attention. To test this hypothesis, we contrast the effects of endogenous attention across two experimental tasks while we recorded electroencephalography (n = 32, both sexes): a single cueing task where endogenous attention is engaged in isolation, and a double cueing task where endogenous attention is concurrently engaged with exogenous attention. Our results confirm that the concurrent engagement of exogenous attention interferes with endogenous attention processes. We also found that changes in alpha-band activity mediate the relationship between endogenous attention and its effect on task performance, and that the interference of exogenous attention on endogenous attention occurs via the moderation of this indirect effect. Altogether, our results substantiate a model of attention, whereby endogenous and exogenous attentional processes involve the same neurophysiological resources.

SIGNIFICANCE STATEMENT: Scientists differentiate top-down from bottom-up visuospatial attention processes. While bottom-up attention is rapidly engaged by emerging demands from the environment, top-down attention in contrast reflects slow voluntary shifts of spatial attention. Several lines of research substantiate the idea that top-down and bottom-up attentional processes involve distinct functional systems. An increasing number of studies, however, argue that both attention systems share brain processing resources. The current study examines how salient visual events that engage bottom-up processes interfere with top-down attentional processes. Using neurophysiological recordings and multivariate pattern classification techniques, the authors show that these patterns of interference occur within the alpha-band of neural activity (8-12 Hz), which implies that bottom-up and top-down attention processes share this narrow-band frequency brain resource. The results further demonstrate that patterns of alpha-band activity explains, in part, the interference between top-down and bottom-up attention at the behavioral level.

ABSTRACT

PURPOSE: The desirability of Orthodontic Residency remains high today relative to the past 30 years. This investigation seeks to re-assess factors influencing Orthodontic Residency program selection amidst contemporary challenges and changes, including increasing student debt, reduced residency stipends, and shifting practice models.

METHODS: This mixed-methods study consisted of interviews (qualitative) and surveys (quantitative). Fifteen final-year dental students and first-year orthodontic residents were interviewed one-on-one following a topic guide and then transcripts were analyzed using MAXQDA2022 to identify values, factors, and influences related to program selection and ranking. Qualitative findings and previous studies provided the basis for a survey distributed to residency applicants in 2020-22. Data were analyzed with bivariate and descriptive statistics with stratification by debt group.

RESULTS: Interviews (N = 15) elevated the importance of location, interview experience, program cost, and clinical education. Surveys (N = 239) identified the most desirable factors for program selection: satisfied residents, strong clinical training with multiple techniques, good interview impressions, low cost, high patient numbers, a strong reputation, and good clinical facilities with new technology. Less desirable factors include programs that are hospital-based, certificate-only, research-intensive, and require considerable after-hours work.

CONCLUSIONS: Clinical education and interview experiences are key for residency selection, consistent with prior studies, though program cost has grown in importance. Findings can help guide orthodontic programs in recruiting applicants and suggest a need to limit educational costs.

ABSTRACT

BACKGROUND: Gingival recession and post-operation discomfort are still a problem for patients receiving the periodontal regeneration surgery for intra-bony defects. To further reduce the trauma and the post-operation gingival recession, a novel periodontal endoscopy-aided non-incisional regeneration technique (NIT) was proposed in the treatment of intra-bony defects.

METHODS: Retrospective analysis of 21 subjects treated with NIT and 21 subjects with periodontal endoscopy-aided scaling and root planing (PSRP) at baseline and 1-year evaluation was conducted. After removing the subgingival calculus and granulation tissue, bone grafting materials were placed into intrabony defects with the assistance of a gingival retractor in the NIT group. Probing depth (PD), gingival recession (GR), clinical attachment level (CAL), as well as the distance between bone crest (BC) level and base of the defect (BD) (intrabony defect depth, IBD) were evaluated at baseline and 1 year after treatment.

RESULTS: At 1-year follow-up, the value of CAL, PD and IBD were statistically significant different compared with baseline in both two groups (p<0.001). CAL gain (p = 0.012) and PD reduction (p = 0.004) was greater in the NIT than PSRP. However, no difference in the IBD reduction was found between the NIT group and PSRP. Better CAL gain and PD reduction was achieved in the 1-year term in the NIT when compared with PSRP.

CONCLUSION: NIT have resulted in significant gains in both clinical and radiographic parameters. NIT might be utilized as an alternative of the surgical treatment for periodontal intrabony defects.

TRIAL REGISTRATION: This clinical trial registration was registered retrospectively (August 3, 2023) and the number is ChiCTR2300074317.

ABSTRACT

BACKGROUND: Abdominally based free flaps are commonly used in breast reconstruction. A frequent complication is venous congestion, which might contribute to around 40% of flap failures. One way to deal with it is venous supercharging. The primary aim of this study was to investigate the scientific evidence for the effects of venous supercharging.

METHODS: A systematic literature search was conducted in PubMed, CINAHL, Embase, and Cochrane library. The included articles were critically appraised, and certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach.

RESULTS: Thirty-six studies were included. Most studies had serious study limitations and problems with directness. Three studies report ‘routine’ use of venous supercharging and performed it prophylactically in patients who did not have clinical signs of venous congestion. Seventeen studies report on flap complications, of which one is a randomised controlled trial demonstrating statistically significant lower complication rates in the intervention group. The overall certainty of evidence for the effect of a venous supercharging on flap complications, length of hospital stay and operative time, in patients without clinical signs of venous congestion, is very low (GRADE ⊕ ⊕ ⊝ ⊝), and low on and surgical takebacks (GRADE ⊕ ⊕ ⊝ ⊝). Twenty-one studies presented data on strategies and overall certainty of evidence for using radiological findings, preoperative measurements, and clinical risk factors to make decisions on venous supercharging is very low (GRADE ⊕ ⊝ ⊝ ⊝).

CONCLUSION: There is little scientific evidence for how to predict in which cases, without clinical signs of venous congestion, venous supercharging should be performed. The complication rate might be lower in patients in which a prophylactic venous anastomosis has been performed.

ABSTRACT

BACKGROUND: Intraoperative 3D imaging using cone-beam CT (CBCT) provides improved assessment of implant position and reduction in spine surgery, is used for navigated surgical techniques, and therefore leads to improved quality of care. However, in some cases the image quality is not sufficient to correctly assess pedicle screw position and reduction, especially due to metal artifacts. The aim of this study was to investigate whether changing the acquisition trajectory of the CBCT in relation to the pedicle screw position during dorsal instrumentation of the spine can reduce metal artifacts and consequently improve image quality as well as clinical assessability on the artificial bone model.

METHODS: An artificial bone model was instrumented with pedicle screws in the thoracic and lumbar spine region (Th10 to L5). Then, the acquisition trajectory of the CBCT (Cios Spin, Siemens, Germany) to the pedicle screws was systematically changed in 5° steps in angulation (- 30° to + 30°) and swivel (- 30° to + 30°). Subsequently, radiological evaluation was performed by three blinded, qualified raters on image quality using 9 questions (including anatomical structures, implant position, appearance of artifacts) with a score (1-5 points). For statistical evaluation, the image quality of the different acquisition trajectories was compared to the standard acquisition trajectory and checked for significant differences.

RESULTS: The angulated acquisition trajectory increased the score for subjective image quality (p < 0.001) as well as the clinical assessability of pedicle screw position (p < 0.001) highly significant with particularly strong effects on subjective image quality in the vertebral pedicle region (d = 1.06). Swivel of the acquisition trajectory significantly improved all queried domains of subjective image quality (p < 0.001) as well as clinical assessability of pedicle screw position (p < 0.001). The data show that maximizing the angulation or swivel angle toward 30° provides the best tested subjective image quality. Angulation and swivel of the acquisition trajectory result in a clinically relevant improvement in image quality in intraoperative 3D imaging (CBCT) during dorsal instrumentation of the spine.
