Response To Exercise

Background & Aims: Sleep is a restorative process for the immune system. There are many situations in which sleep is disturbed prior to an athletic event. However, the effect of sleep deprivation on immune indices in response to exercise remains unknown. The aim of this study was to investigate the effects of sleep deprivation on serum IgG responses to aerobic activity. Materials & Methods: In this quasi-experimental study, 10 male physical education students were voluntarily participated. Study was performed in two separate occasions; control and experimental within two weeks. In the control occasion, normal sleep and aerobic activity and in the experimental occasion, sleep deprivation and aerobic activity was applied. Aerobic activity was performed on bicycle ergometer for 30 minutes at intensity of 70 to 75 percent of maximum heart rate. Changes in serum IgG concentrations in pre-test, before and after aerobic activity in both occasions were analyzed by the two repeated measures ANOVA and dependent T-test using SPSS software. Results: The results showed that sleep deprivation not significantly effect on Serum IgG response to aerobic activity (p=0.130). Also, aerobic activity not significantly effect on Serum IgG concentration (p=0.357). But sleep deprivation caused a significantly increase in serum IgG concentration (p=0.035). Conclusion: No significant effect of sleep deprivation on serum IgG concentrations response to aerobic activity.

In this article, we reviewed results of research on near-death experiences (NDEs) over the past 3 decades and examined the effect of viewing the hour-long 2002 BBC documentary The Day I Died: The Mind, the Brain, and Near-Death Experiences on accurate knowledge about near-death experiences among advanced undergraduates at a southwestern university. In a quasi-experimental research design, the experimental group completed a 20-item questionnaire before and after viewing the documentary ( n = 66; 45 females, 21 males), and the waitlist control group completed the questionnaire as pre- and posttest before viewing the documentary ( n = 39; 36 female, 3 male). The two groups' scores at pretest were not significantly different ( p > .05). Group by occasion repeated measures ANOVA revealed the experimental group's posttest scores moved significantly in the direction of correctness with a large effect size ( p < .001; η2= .56), whereas waitlist control group posttest scores remained similar to pretest scores. We discuss two exceptions to the effectiveness of the documentary and recommendations for educators using it as well as for future research.

Background: Cortical macrostructure is influenced by circadian rhythm and sleep deprivation, yet the microstructural underpinnings of previous human brain MRI findings have remained unclear. The ratio between T1-weighted and T2-weighted magnetic resonance images (T1w/T2w ratio) has been linked to myelin levels and dendrite density, and may offer novel insight into the intracortical microstructure of the sleep deprived brain. Methods: We examined intracortical T1w/T2w ratio in 41 healthy young adults (26 women) before and after 32 hours of either sleep deprivation (n = 18) or a normal sleep-wake cycle (n = 23). Results: Linear models revealed significant group differences in T1w/T2w ratio change after 32 hours in four clusters, including bilateral effects in the insular, cingulate and superior temporal cortex, comprising regions involved in attentional, auditory and pain processing. Across clusters, the sleep deprived group showed an increased T1w/T2w ratio, while the normal sleep-wake group exhibited a reduced ratio. These changes were not explained by in-scanner head movement, and 95% of the effects across clusters remained significant after adjusting for cortical thickness and hydration. Conclusions: Compared with a normal sleep-wake cycle, 32 hours of sleep deprivation yields intracortical T1w/T2w ratio increases. While the intracortical changes detected by this study could reflect alterations in myelin or dendritic density, or both, histological analyses are needed to clarify the precise underlying cortical processes.

The objective of the study is to determine the effect of group counseling on academic stress of senior high school students. Academic stress is a student's response to academic demands that cannot be prevented, avoided or controlled. Respondents in this study were four senior high school students who had high academic stress scores. This study used a quasi-experimental one-group pretest-posttest design. Researchers measured respondents' academic scores before and after the group counseling was given. Researchers used the Educational Stress Scale for Adolescents (ESSA) to measure the academic stress of respondents. The treatment given, which was group counseling, was given in five sessions. Researchers used anava repeated measures to analyze the data. From the statistical analysis conducted, it can be concluded that group counseling has a significant effect on reducing the academic stress of the research respondents. From the results of this study, researchers suggest that group counseling is effective for reducing academic stress in senior high school students.

ABSTRACT Objective: to evaluate the effectiveness of auriculoacupuncture in improving the sleep quality of nursing professionals in the fight against the COVID-19 pandemic. Method: quasi-experimental before and after study, without a control or matching group performed from May to July 2020, in a referral hospital for infectious diseases in Ceará. The sample consisted of 26 nursing professionals, including nurses and technicians, who performed three sessions of auriculoacupuncture, once a week, for four weeks. Sleep quality was measured by the Pittsburg Sleep Quality Index. The effects of the intervention were analyzed by the student's “t” test to compare means between the first and last application, one-way ANOVA with repeated measures and post-hoc Sidak´s test. Results: regarding the components of the Pittsburg Sleep Quality Index, significant differences were observed between the individuals in the components: subjective sleep quality (p=0.001); sleep latency (p<0.001), sleep duration (p<0.001), habitual sleep efficiency (p=0.011), sleep disorders (p<0.001), sleeping medications (p=0.005) and excessive daytime sleep sleepiness (p<0.001). The overall sleep index also changed significantly (p<0.001). The intervention reduced the sleep quality index score by 52.35%. Conclusion: the changes that occurred were able to change the category in sleep classification through a detailed decrease in the Pittsburg Sleep Quality Index scores. Significant differences were observed between the first and final moments in the global index and in all components.

BACKGROUND: Although preoperative education decreases the anxiety of patients and family members, the usefulness of a preoperative tour of the ICU has not been studied. In this study, the effect of an ICU tour on the anxiety levels of patients (n = 92) and family members (n = 91) before and after cardiac surgery was examined. METHODS: Using a pretest-posttest quasi-experimental design, patients and family members were assigned to a control group, which received preoperative teaching only (patients, n = 48; family members, n = 48), or to an experimental group, which received preoperative teaching with an ICU tour (patients, n = 44; family members, n = 43). Patients and family members completed two measures of anxiety, the State Trait Anxiety Inventory and a visual analog scale, before and after the intervention. After their first postoperative visit, family members completed the measures again. Repeated measures analysis of variance was used to compare anxiety levels after the intervention. In addition, patients completed the Patient Perception of the ICU Tour Questionnaire after transfer from the ICU. RESULTS: Although patients and family members had a decrease in anxiety after cardia surgery teaching, the decrease was not due to an ICU tour. However, the majority of patients who toured the ICU perceived the tour as beneficial and recommended a tour for future patients. CONCLUSIONS: ICU tours are included in many cardiac surgery educational programs. The majority of patients in this study perceived a benefit or a future benefit from an ICU tour, even though the tour did not significantly reduce the anxiety of the patients or family members.

Staggered Entry

Effective communication between clinicians is a crucial component of safe care. High-quality communication may be especially critical during care transitions between clinicians (handoffs). In a two-year quasi-experimental Quality Improvement project, we are using simulation learning to evaluate and improve communication between anesthesia providers and nurses as care is transitioned from the operating room to the post-anesthesia care unit (PACU). Using a multiple baseline, staggered entry, prospective cohort design with repeated measures, we are introducing a training intervention and evaluating its effects on dyadic communication. The primary hypothesis is that simulation-based communication skills training of PACU personnel will significantly improve the quality of handoffs. Clinicians' performance is being compared before and after their training on four dimensions of handoff effectiveness: information transfer; use of best evidence handoff strategies; interpersonal skills; and team behaviors. Clinicians also rate their own handoffs. Lessons learned and results to date will be presented.

The Impact

Purpose. The present study aimed to investigate the impact of a 6-month multicomponent exercise program (MCEP) on physical function and cognitive parameters of normotensive (NTS) and hypertensive (HTS) older patients and verify if age can influence the adaptations in response to the exercise.Methods. A total of 218 subjects, 101 NTS and 117 HTS, were recruited and underwent functional and cognitive evaluations before and after six months of a MCEP. The program of exercise was performed twice a week, for 26 weeks. The physical exercises were thought to mimic the activities of daily living and, therefore, aggregated functional and walking exercises. Exercise sessions were performed at moderate intensity.Results. Data indicated that HTS and NST patients showed a similar increase in the performance of walking speed test and one-leg stand test after the MCEP. Regarding age, results did not show differences in the magnitude of adaptations between old and young HTS and NTS patients.Conclusions. Data of the present study indicated that a 6-month MCEP was able to increase equally balance and mobility in NTS and HTS patients. Moreover, data demonstrated that aging did not seem to impair the capacity to adapt in response to exercise in both groups.

Financial Crisis Of 2008

Most companies listed on the Standard & Poor’s 500 (S&P 500) index have smoothed reported earnings since the 1990s inspiring questions from regulators about the accuracy of financial statements. In 2002, the Sarbanes-Oxley Act (SOX) was issued to eradicate earnings management activities and improve transparency in financial reporting. Although many studies have been conducted to evaluate changes in reporting requirements, much less is known about the effectiveness of these regulations on earning smoothing with discretionary accruals (DA). Accordingly, this study was an investigation of DA from 2002 to 2011. In addition, this study included an evaluation of DA before and after the financial crisis of 2008. This study is a quasi-experimental research design where 330 observations from the U.S. financial industry segment were used for the analysis. The Modified Jones model was used to separate DA and repeated measures analyses of variance were used to assess differences in levels before and after the financial crisis of 2008. The findings suggest DA activities are decreasing but represent over 50% of total net accruals (TNA) for all years. Improved financial regulation is needed. The study contributes to positive social change by providing regulators and investors with new information about accruals for income conservative firms by segmenting DA within the financial industry segment.

Aggression is a behavior that intent to hurt others. Despite collective researches about aggression, there is a dearth in fully established psychosocial programs for the Children in Conflict with the Law (CICL) and evaluating program directed to aggressive behavior in the Philippines. Eight CICL housed in an institution under the supervision of the DSWD-Dasmariñas were the primary source of data. The study seeks to describe the pre-and-post mean scores of aggressions and determine the significant difference in aggression reduction before and after exposure to AMP. Employing the quasi-experimental design, the researchers administered the intervention and conducted repeated-measures to measure the effectiveness of AMP thru combined approaches of CBT-EFT in reducing their aggression level. Findings revealed that their aggression in the areas of physically aggressive responses, and verbally aggressive reactions were diminished after participating in the AMP, with the inclusion of counseling sessions in addressing problematic concerns related to aggressive behavior.
