Comparison of Two Different Intervals of Misoprostol Administration in Second Trimester Abortions.

Objective: Comparison of two different intervals of misoprostol administration after mifepristone in second trimester abortions. Materials and methods: This 12-month prospective study was conducted at a tertiary care facility. Only pregnancies with congenital deformity or sterilisation failure were included in the study's recruitment of 100 women who visited the hospital for a second trimester abortion between 12 and 20 weeks; cases with scarred uteri were omitted. In a systematic random selection of 50 women in each group, the administration of 200 mg of mifepristone orally was followed by two distinct intervals of intravaginal misoprostol administration at 24- and 48-hour intervals. After 24 hours, group A women received intravaginal 400 mcg misoprostol three hourly, up to a maximum of five doses, while group B received the same doses after 48 hours. Induction abortion interval noted on various parameters and paired t test and chi square test applied. Results: The mean IAI following misoprostol administration was 8.14 2±.03 hours in group A and 7.71 ±2.56 hours in group B. This difference was statistically insignificant. Average misoprostol doses for group A were 1.68±0.71 and for the group, B were 1.68±0.84; both doses were found to be statistically insignificant when used to induce abortion. All women aborted successfully in each group. There was no significant difference in side effects in both groups. Conclusion: Based on the results it was observed that shorter interval between mifepristone and misoprostol i.e., 24 hours can be chosen to decrease the hospital stay as there was no significant difference was seen after intravaginal misoprostol in terms of induction abortion interval, number of doses and side effects.

You stay home, but we can't: Invisible 'dirty' work as calling amid COVID-19 pandemic.

Research on calling has largely focused on its benefits for employees. This study contends that experiencing work as a moral duty based calling in invisible-dirty occupations can yield both favorable and unfavorable employee outcomes. Whether employees feel burdened or supported in their work and family roles depends on the demands and resources provided by the workplace. In a sample of 175 janitors at a large government hospital designated for treating COVID-19 patients in the national capital region of India, hypothesis testing results support that work calling is positively associated with both positive (job performance, subjective career success), and negative (work-family and family-work conflicts, burnout) outcomes. Further, job demands strengthen the relationship of work calling with work-family and family-work conflicts, and burnout, whereas, job resources augment the relationship between work calling and job performance, and subjective career success.

Individual deals within teams: Investigating the role of relative i-deals for employee performance.

The authors extend i-deals theory to an individual-within-a-team context. Drawing upon social comparison theory, they contend that individuals will react to their own i-deals within the context of group members' i-deals. Therefore, they examine the role of relative i-deals (an individual's i-deals relative to the team's average) in relation to employee performance. Furthermore, integrating social comparison theory with social identity theory the authors assert that the behavioral outcomes of relative i-deals are influenced by the team's social and structural attributes of team orientation and task interdependence. Finally, they contend that the perceptions of one's relative standing with the leader, or leader-member exchange social comparison (LMXSC), mediate the i-deals-outcome relationship in groups with low team orientation and task interdependence. Results of multilevel modeling using time-lagged data from 321 employees nested in 46 teams demonstrated that the positive relationship between relative i-deals and employee performance was stronger in groups with low team orientation and task interdependence, and the mediation effect of LMXSC was stronger in teams with low rather than high team orientation.

Anesthesia and cancer recurrences: The current knowledge and evidence.

Surgical removal of solid tumors is of utmost importance as total resection can be curative. The surgical insult however itself may result in tumor micrometastasis coupled with depression of cell-mediated immunity culminating in tumor recurrence. Recent research suggests that few anesthetic agents or procedures can influence pathophysiology of metastasis in the postoperative period. Whereas opioids and volatile anesthetics have been implicated in angiogenesis and immunosuppression, evidences accumulated over the recent years have undoubtedly highlighted the attenuation of immunosuppression by regional anesthetic agents thereby making it superior over general anesthesia in preventing cancer recurrence. As anesthetic drugs are given at that time when patient is at the maximum risk of spread of metastasis, thus an understanding of the effect of anesthesia drugs and their impact on tumor metastasis is important so that appropriate anesthetic strategy can be made to improve long term survival in these patients. The purpose of the present review is therefore to emphasize the pivotal role of various anesthetic agents and anesthesia techniques in preventing tumor recurrence after surgery.

Perils of paediatric anaesthesia and novel molecular approaches: An evidence-based review.

Evolution of anaesthesia has been largely helped by progress of evidence-based medicine. In spite of many advancements in anaesthesia techniques and availability of newer and safer drugs, much more needs to be explored scientifically for the development of anaesthesia. Over the last few years, the notion that the actions of the anaesthesiologist have only immediate or short-term consequences has largely been challenged. Evidences accumulated in the recent years have shown that anaesthesia exposure may have long-term consequences particularly in the extremes of ages. However, most of the studies conducted so far are in vitro or animal studies, the results of which have been extrapolated to humans. There have been confounding evidences linking anaesthesia exposure in the developing brain with poor neurocognitive outcome. The results of animal studies and human retrospective studies have raised concern over the potential detrimental effects of general anaesthetics on the developing brain. The purpose of this review is to highlight the long-term perils of anaesthesia in the very young and the potential of improving anaesthesia delivery with the novel molecular approaches.

One member, two leaders: extending leader-member exchange theory to a dual leadership context.

In this study, we develop and test a model that extends leader-member exchange (LMX) theory to a dual leadership context. Drawing upon relative deprivation theory, we assert that when employees work for 2 leaders, each relationship exists within the context of the other relationship. Thus, the level of alignment or misalignment between the 2 relationships has implications for employees' job satisfaction and voluntary turnover. Employing polynomial regression on time-lagged data gathered from 159 information technology consultants nested in 26 client projects, we found that employee outcomes are affected by the quality of the relationship with both agency and client leaders, such that the degree of alignment between the 2 LMXs explained variance in outcomes beyond that explained by both LMXs. Results also revealed that a lack of alignment in the 2 LMXs led to asymmetric effects on outcomes, such that the relationship with agency leader mattered more than the relationship with one's client leader. Finally, frequency of communication with the agency leader determined the degree to which agency LMX affected job satisfaction in the low client LMX condition.

Where do I stand? Examining the effects of leader-member exchange social comparison on employee work behaviors.

Taking an approach integrating principles of leader-member exchange (LMX) differentiation with social comparison theory, we contend that subjective ratings by individuals of their LMX compared to the LMXs of coworkers (labeled LMX social comparison, or LMXSC) explain unique and meaningful variance in outcomes beyond LMX and the actual standing of those individuals in the LMX distribution, referred to as relative LMX, or RLMX. Our findings demonstrate that employees' perceptions of LMXSC are positively related beyond the effects of LMX and RLMX to job performance and citizenship behaviors. Further, we argue that LMXSC mediates the RLMX→outcomes relationships. Analyses showed that, in a sample of 254 employees nested in 50 work groups, a significant part of the effects of RLMX on job performance and citizenship behaviors was mediated through LMXSC after controlling for LMX.

Optical excitations in carbon architectures based on dodecadehydrotribenzo[18]annulene.

The origin of excitations in multi-chromophore carbon network substructures based on dodecadehydrotribenzo[18]annulene has been investigated by steady-state and photon echo spectroscopy, configuration interaction (CIS and CIS(D)), and time-dependent density functional theory (TD-DFT). 1,4-diphenylbutadiyne, the simplest structural subunit within the annulene, was used in modeling the spectroscopic studies to explain the origin of excitations in the macrocycles. The optical excitations in longer linear systems were found to be similar to its diphenylacetylene analogue. However, the results from dodecadehydrotribenzo[18]annulene and other multichromophore networks systems illustrate the possibility of strong intramolecular interactions and the formation of delocalized excited states. Calculations were carried out to explain the basic similarities and differences in excitations of the model compounds such as diphenylbutadiyne and the macrocycles. The fundamental excitation in these systems can be primarily described as a pi --> pi* transition. Two low-energy resonances were observed from experiment for the annulene systems, and possible explanations for these low-energy resonances in the macrocycles are explored. The significant difference found in the calculated oscillator strength of the two low-energy bands for the macrocycles as well as the dynamics of solvent interactions was further investigated by three-pulse photon echo measurements. A simple exciton model was developed to discuss the excitations in the larger macrocycles. The results from this model were found to be in good agreement with the TD-DFT calculations.

Dissociation of benzene dication [C6H6]2+: exploring the potential energy surface.

The singlet potential energy surface for the dissociation of benzene dication has been explored, and its three major dissociation channels have been studied: C6H6(2+) --> C3H3(+) + C3H3(+), C4H3(+) + C2H3(+), and C5H3(+) + CH3(+). The calculated energetics suggest that the products will be formed with considerable translational energy because of the Coulomb repulsion between the charged fragments. The calculated energy release in the three channels shows a qualitative agreement with the experimentally observed kinetic energy release. The formation of certain intermediates is found to be common to the three dissociation channels.
